Description

  The present invention relates to a slot machine that rotates a plurality of reels on which a plurality of symbols are displayed, then stops the reels rotated according to the result of the winning lottery, and determines a game result by a combination of symbols at the time of stoppage. In particular, the present invention relates to a role lottery performed for each game.

A slot machine in which a player inserts a game medium, rotates a plurality of reels on which a plurality of symbols are displayed based on the player's operation, stops, and determines a game result by a combination of symbols at the time of stop, Widely used as one of gaming machines. In this slot machine, a winning lottery is performed for each game, and when a symbol corresponding to the winning combination in the winning lottery stops and a winning is won, a winning process corresponding to the winning winning combination is performed. This winning process includes, for example, payout of game media, transition to a winning game where the game proceeds in a state advantageous to the player, and the result of the role lottery is a matter that shows the player's highest interest It is.
Therefore, there is a risk that an act that intentionally causes a bias in the result of the lottery, that is, causes a specific role to be biased and won.

As such an artificial action, for example, when performing a role lottery using a random number generated by adding every clock pulse, this generation cycle is calculated by utilizing the fact that the same random number value is periodically generated. For example, there is an act of taking out a specific random number by recognizing by some means and winning a certain combination in a combination lottery.
In order to prevent such an action of taking out a specific random number, a slot machine has been proposed in which a random number generated by software is further added to a random number generated by a random number generator. (For example, refer to Patent Document 1.)
JP 2003-126333 A

  In the slot machine proposed in Patent Document 1, an attempt is made to eliminate the periodicity of the random number generated by the random number generator by adding the random number generated by the software to the random number generated by the random number generator. Yes. However, the update speed of random numbers when using software is slower than the update speed of a random number generator, and is not sufficient to eliminate the periodicity of random number generation. It is not enough to prevent the act.

  Therefore, the object of the present invention is to solve the above-mentioned problems and to prevent an artificial act that intentionally causes a bias in the result of the role lottery. Even so, an object of the present invention is to provide a slot machine that can effectively prevent the result of the role lottery from being biased.

  In order to achieve the above object, as a slot machine according to the present invention, a slot machine capable of performing a game in which a process for rotating and stopping a plurality of reels displaying a plurality of symbols is performed once. And after rotating a plurality of reels on which a plurality of symbols are displayed, and a lottery means for performing a combination lottery for performing at least one winning combination from among a plurality of combinations by lottery processing, According to the result of the lottery, the reel control means for controlling the rotation of the rotated reels, and a flag is set when a predetermined role is won in the role lottery. Winning combination control means for performing a winning process corresponding to the winning combination when it is determined that the combination of symbols corresponding to the winning combination has been stopped, and the winning lottery means includes n1 to n2 Random number acquisition means for generating N random numbers (N = (n2−n1) / K + 1) increasing in increments of new value K and taking out one random number, and the order in which lottery determination is performed for each role and disparity (hereinafter, “Determination order”) is determined according to the determination order determining means for each game based on predetermined requirements, and the winning data is determined according to the winning probability for each combination and out of game, and the total value of the probability data matches the N Using the random number extracted by the random number acquisition means in the determination order determined by the determination order determination means, and a value obtained by multiplying the probability data corresponding to each role and deviation by the update value K. When it is determined that the addition value is larger than n2 or when the subtraction value is smaller than n1, the role corresponding to the probability data added or subtracted last is added or subtracted in order. A lottery determining means performs the lottery determination defining the winning disengagement, it is conceivable that with a.

In the slot machine of the present embodiment, usually, a game medium is inserted, a plurality of reels on which a plurality of symbols are displayed are rotated and stopped, and a winning process corresponding to a stop symbol including a payout of the game medium is performed. A game can be repeated once. Here, the game medium is a medium inserted into the slot machine for playing a game, and for example, a coin, a medal, or a chip can be considered. Moreover, as long as this object can be achieved, the product is not limited to an article, and for example, an electromagnetically acting material such as a magnetic card can be applied.
In addition, the introduction of the game medium includes a case where the player actually inserts a game medium from a game medium insertion port provided in the slot machine or the like. Using a predetermined number of credited game media is also included.

  Here, the “combination” generally includes a “winning role” for performing a “winning game” that makes the game proceed in an advantageous manner for the player, and a “replaying game” in which the game can be re-executed without inserting a game medium. "Re-game combination" for "and a" general combination "for paying out a predetermined number of game media when winning.

“Winning” refers to performing “winning game” in which a game progresses in an advantageous manner for a player when a winning combination is won by lottery and a symbol corresponding to the winning role stops and wins a prize. It is a possible role. The winning combinations include a regular bonus combination (hereinafter referred to as RB combination) and a big bonus combination (hereinafter referred to as BB combination).
The RB combination is a combination that shifts to an RB game that is one of the winning games. In this RB game, a game in which a predetermined combination is won with a high probability can be performed a predetermined number of times under a certain condition. In addition, the BB role is a role for shifting to a BB game that is one of the winning games. This BB game can be used for general games and can be transferred to RB games under certain conditions during the general games. This is a game in which a general game and an RB game can be repeated until a predetermined number of game media payouts is reached.

“Re-game” is a “re-game” that can be re-executed without throwing in game media when a symbol corresponding to the re-game player stops and wins a prize. It is also a role that can be carried out. Further, when the re-gamer wins and wins, the re-game can be performed with the same specified number as the re-gamer won, or can be re-played with a different specified number. An arbitrary number can be used as the specified number. It is also possible to set a plurality of types of re-game players.
The “general combination” is a combination in which a predetermined number of game media are paid out when a general combination is won by lottery and a symbol corresponding to the general combination is won. A case where a plurality of winning combinations (for example, winning combinations and general winning combinations) are simultaneously won in one winning lottery can be considered as one of the winning combinations.

  In the “role lottery” for determining at least one combination, for example, it is desirable to generate a random number and determine one winning combination based on the value. For the generation of random numbers, a hard random number generator may be used, or a soft random number generator generated on software may be used.

In the present embodiment, N random numbers (N = (n2−n1) / K + 1), which are incremented by the update value K from n1 to n2, are generated, and a role lottery is performed using the one random number extracted. Here, when the update value K = 1, the random number is an integer that increases by one, and when the update value K is 2 or more, the random number is a continuous integer at a constant interval. As the value of K, an integer having an arbitrary value can be used. Therefore, more various random number generation modes can be used, which is effective in preventing a situation in which a certain random number value is biased and extracted by human action. Moreover, arbitrary values can be used for the values of n1 and n2.
Probability data is determined in accordance with the winning probability for each combination and outlier, and the total value of the probability data matches the total number N of random numbers. That is, the value obtained by dividing the probability data set for each combination and out of the game by the total number N of random numbers is the winning probability for each combination and out of game.

  In addition, the determination order, which is the order in which the lottery determination is performed using the probability data set for each combination and out of play, is determined based on predetermined requirements for each game by the determination order determination means. Here, as the predetermined requirement, for example, as will be described later, it can be determined by selecting one determination order table from a plurality of determination order tables in which the determination order is determined in advance. It can also be determined by using. Further, it may be determined based on an event that has occurred in one or a plurality of completed games. For example, it may be determined using a gaming state, the number of rotation steps of a reel, a signal transmission state, and the like. Furthermore, the determination order can be determined based on all other requirements. In any case, it is desirable to determine the determination order in a manner that is difficult for a person who performs an artificial act to determine.

  The lottery determination process is performed in the order determined by the determination order determination unit, and the random number extracted by the random number acquisition unit is multiplied by the probability data corresponding to each combination and outlier by the update value K in order. When it is determined that the added value is larger than n2, the addition type lottery determination that determines that the winning combination or disparity corresponding to the probability data added at the end is the winning, and the determination order determined by the determination order determining means, The random number extracted by the random number acquisition means is sequentially subtracted by the value obtained by multiplying the probability data corresponding to each role and outlier by the update value K. When it is determined that the subtraction value is smaller than n1, the value is finally subtracted. There is a subtractive lottery determination in which a winning combination or a gap corresponding to the probability data is determined as winning.

  Therefore, even if the same random number is taken out by the random number acquisition means, if a different determination order is determined by the determination order determination means, a different combination and out of play is determined as winning. Further, even when the same random number is taken out and in the same determination order, different roles and deviations occur when the lottery determination process is performed using the addition type lottery determination and when the lottery determination process is performed using the subtraction type lottery determination. Is determined to be a winner. Whether to use addition-type lottery determination or subtraction-type lottery determination is determined based on various requirements such as using random numbers for each game, as in the case of determining the determination order. Can do. In this case, as in the case of determining the determination order, it is desirable that the determination be made by a method that is difficult for a person who performs an artificial action to determine.

The “reel on which the symbol is displayed” includes a reel that is physically rotated and stopped by a motor or the like, and a reel on the image that is displayed on the display device and is rotated and stopped on the image. It is. The “reel control means” starts rotation of the reel when receiving a signal transmitted based on the start operation of the player, and rotates when receiving a stop signal transmitted based on the stop operation of the player. The stop control of the reel being performed is performed.
In this case, it is possible to set the rotation of all the reels to be started by one start operation, and based on the operation corresponding to each reel, the rotation is set to start only the reel that has been started. It is also possible. Similarly, it is possible to set the rotation of all reels to be stopped by one stop operation, or to set only the reels that have been stopped based on the operation corresponding to each reel. Is possible.

“Corresponding symbol combinations stop” means, for example, that symbols determined corresponding to roles for each reel stop on a predetermined effective line, and predetermined symbols are aligned. . In this case, a case where a symbol to be stopped is defined for all reels is included, and a case where a symbol to be stopped for some reels is also included. The symbols to be stopped can be set to the same symbol for all reels, or different symbols can be set for each reel.
Conversely, “the corresponding symbol combination does not stop” means that the requirement for corresponding to the above “corresponding symbol combination stops” is not satisfied. Therefore, for example, even when the symbols to be stopped on some of the required reels do not stop, “does not stop”. Of course, even when the symbols to be stopped on all the required reels do not stop, it does not stop.

  “Set a flag” means to set a gaming state in which a predetermined winning process can be performed if a combination of corresponding symbols stops and a winning is made when a predetermined winning combination is won in the winning lottery. Meaning and control, the flag is stored in the storage device (RAM) of the control means.

As described above, in this embodiment, since the determination order is determined for each game based on predetermined requirements, if the determination order is changed for each game, the same random number is continuously extracted. However, it is possible to prevent the same combination from being won continuously. Therefore, even if a situation occurs in which a certain random number value is biased due to human behavior, the result of a role lottery is biased, that is, a situation where a certain role is biased in a role lottery is prevented. can do. In particular, with respect to the predetermined requirement for determining the order of determination, it is possible to more effectively prevent the result of the role lottery from being biased by setting an event that cannot be determined by a person who performs an artificial act.
In addition, even if the order of determination is the same, the winning lottery and the disparity differ depending on whether the addition-type lottery determination is used or the subtraction-type lottery determination. Can be prevented.
In the above-described embodiment, the determination order of each combination and out of play is determined for each game. However, the slot machine according to the present invention is not limited to this, for example, every time a plurality of games are digested. The determination order can also be determined, the determination order can be determined a plurality of times in one game, and the determination order can be determined at any other timing.

  Further, as the slot machine according to the present invention, when the same determination order is continuously determined for a certain number of games or more based on the determination order and the winning lottery history, or the same winning combination is fixed in the winning lottery. It may be possible to further include a role lottery monitoring means for performing a control process in order to carry out an abnormality notification when the player has won more than the number of games.

Here, for the “fixed number of games” in which the same determination order is continuously determined and the “fixed number of games” for winning the same combination in the lottery, any number can be set. Can be set, or the same number of times can be set. In addition, the “control processing to perform abnormality notification” includes, for example, control processing for sounding an alarm and control processing for notifying that an abnormal situation has occurred using a display device or a lamp. Any control process for notifying an abnormal situation is included. In addition, it is also conceivable to perform a control process so as not to accept a game medium input or start operation.
As described above, by setting the determination order for each game, it is possible to effectively prevent the result of the role lottery result due to an artificial action. However, according to this embodiment, the same determination order is continuous. Even if the same role is won continuously, the role lottery monitoring means performs control processing to carry out abnormality notification, thereby minimizing the occurrence of disadvantage caused by human acts To the limit.

  As the slot machine according to the present invention, the determination order determining means further includes a plurality of determination order tables that determine the determination orders of the respective roles and deviations, and the plurality of determination order tables based on a predetermined condition. It is conceivable that one determination order table is selected from among the two, and the determination order of each combination and outage is determined based on the selected determination order table.

  Here, in each determination order table, it is set so that at least a part of the determination order of each combination and outlier is different, and theoretically, the number of determination order tables is the number of combinations and outliers. If the number is m, a maximum of m permutations can be provided. However, it is not always necessary to provide the maximum number of judgment order tables. It is an artificial act to provide a plurality of judgment order tables with different judgment orders for a role that has a large benefit to the player as represented by a winning combination. This is effective in preventing the result of the role lottery from being biased.

  As a “predetermined condition” for selecting one determination order table from among a plurality of determination order tables, for example, one determination order table can be selected from a plurality of determination order tables by lottery using random numbers. Conceivable. In this case, a random number in the role lottery can be used, or a random number generated by another random number generator can be used. Also, a so-called hard random number using a hard random number generator can be used, or a so-called soft random number generated on software can be used.

In addition, it may be determined based on an event that has occurred in one or a plurality of completed games. For example, one determination order table is selected using a game state, the number of rotation steps of a reel, a signal transmission state, and the like. You can also Furthermore, one determination order table can be selected using any other conditions.
According to this embodiment, it is very difficult for a person who performs an artificial action to determine the determination order determined by the determination order determination means, and a situation in which the result of the role lottery is biased by the human action. It can be effectively prevented.

  Further, as the slot machine according to the present invention, the determination order determining means generates a random number for each combination and outage, and based on the value of the random number acquired for each combination and outage, each combination and outage It is conceivable to determine the determination order.

  As a random number used in the present embodiment, a random number in a role lottery can be used, or a random number generated by another random number generator can be used. In that case, a so-called hard random number using a hard random number generator can be used, or a so-called soft random number generated on software can be generated. Further, a combination of a plurality of acquired random values, for example, an operation value obtained by performing a predetermined operation including four arithmetic operations using a plurality of random values can be used.

Here, “determining the order of determination based on the value of the random number acquired for each combination and outage” means that, for example, a random number is generated for each combination and outage, and a random number of 1 is extracted and acquired. It may be possible to determine the order of determination in ascending order of values, or conversely, it may be possible to determine the order of determination in descending order of the acquired random number value. It is conceivable to determine the order, it is conceivable to determine the order of determination by giving priority to odd-numbered winnings and deviations, and it is also possible to determine by combining these rules. Furthermore, the determination order can be determined using any other method.
According to this embodiment, it is very difficult for a person who performs an artificial action to determine the determination order determined by the determination order determination means, and a situation in which the result of the role lottery is biased by the human action. It can be effectively prevented.

  Further, as the slot machine according to the present invention, it is conceivable that the update value of the random number generated by the determination order determining means for each combination and outlier is a prime number having a different value.

  In this embodiment, since the update value of the random number generated for each winning combination and outlier is a prime number having a different value, the same random number is not generated in each winning combination. It is possible to reliably determine the determination order corresponding to the combination and out of correspondence, and to quickly set the determination order.

  Further, as the slot machine according to the present invention, the determination order determining means generates a random number, and the determination order of each combination and out of order based on information contained in all or some bits of the acquired random number. It is conceivable that

Here, “determining the determination order based on information of all or some of the bits of the acquired random number” means that all the digits of the acquired random number or some of the digits (for example, the higher order bits) Based on the information of 4 bits, lower 4 digits, etc.), for example, using bit information (for example, whether the bit is set (whether the value is 1 or 0)) It is conceivable to determine the judgment order. More specifically, for example, each digit of the random number is associated with each combination and out of priority, and the determination order of the combination and out of correspondence with the digit having a bit (value is 1) is given priority. Alternatively, it may be possible to preferentially determine the order of determination of the combination and the deviation corresponding to the digit where the bit is not set (the value is 0). Further, the total number of digits in which the bits are set out of all or some of the bits of the obtained random number (for example, the upper 4 digits, the lower 4 digits, etc.) is odd or even. It is also possible to determine the order of determination depending on whether there are, for example, for the roles and deviations arranged in a predetermined order, depending on whether it is odd or even, the direction in which the order of determination is determined (for example, if they are arranged on the left and right , A right-to-left direction, or a left-to-right direction). It is also conceivable to determine the determination order by combining these conditions.
According to this embodiment, it is very difficult for a person who performs an artificial action to determine the determination order determined by the determination order determination means, and a situation in which the result of the role lottery is biased by the human action. It can be effectively prevented.

According to the above-described invention, it is possible to change the determination order for each game, and even if the same random number is continuously taken out, it is possible to prevent the same combination from being won continuously. Therefore, even if a situation occurs in which a certain random number value is biased and extracted due to human acts, the result of the role lottery is biased, that is, the situation where a certain role is biased in the role lottery is effective. Can be prevented.
In addition, with regard to the requirements for determining the determination order, by using an event that is difficult for a person who performs an artificial action to discriminate, such as when using a plurality of determination order tables or using a random number value, The bias in the result can be more effectively prevented.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

When the player pushes the stop switch 52L, the left reel 40L stops. When the player pushes the stop switch 52C, the middle reel 40C stops. When the player pushes the stop switch 52R, the right reel 40R stops.
When the reels 40L, 40C, or 40R are stopped, the three reels 40L, so that the symbols drawn on the outer peripheral surfaces of the reels are positioned on the winning lines L1, L2A, L2B, L3A, and L3B described above. Each of 40C or 40R is controlled to stop.

On the lower right side of the casing of the slot machine 10, sound is emitted from a speaker (not shown, corresponding to a speaker 64 shown in FIG. 3 described later) housed in the casing. A sound transmission hole 60 is provided for exiting to the outside. A game medium payout port 62 is provided at a central portion below the casing of the slot machine 10. When the reels 40L, 40C, or 40R are stopped and the symbols that are stopped and displayed on the active line become a predetermined combination, that is, a symbol that constitutes a winning combination. A predetermined number of game media are paid out from the game media payout port 62.
As described above, the game in the slot machine 10 is a game in which a game result is determined by a combination of symbols determined by the stopped positions of the stopped reels 40L, 40C, or 40R. This game is performed every time the player tilts the start switch 50, and the process from the start of rotation of the reels 40L, 40C, or 40R to the stop of rotation can be repeated as one game. is there.

Examples of the types of combinations described above include types such as winning combinations, general combinations, and re-playing combinations. The winning combination is a combination in which when a winning combination is won by lottery and when a winning combination is awarded according to the winning combination, a winning game that allows the player to advance the game advantageously can be performed. In addition, the general combination is a combination in which a predetermined number of game media are paid out when a general combination is won by lottery and a symbol corresponding to the general combination is won. In addition, when the re-gamer is selected as a re-gamer in a lottery and the symbols corresponding to the re-gamer are all won, a re-game (also referred to as replay) is performed without newly inserting a game medium. It is a role that can be performed.
The winning combination includes a big bonus combination (hereinafter referred to as BB combination), a regular bonus combination (hereinafter referred to as RB combination), and the like. Note that a case where a plurality of winning combinations (for example, winning combinations and general winning combinations) are simultaneously won in one winning lottery can be considered as one of the winning combinations.

  The RB combination is a combination to shift to an RB game that is one of the winning games. This RB game is a game in which a game in which a predetermined combination is won with a high probability is performed a predetermined number of times under a certain condition. Further, the BB combination is a combination that shifts to a BB game that is one of the winning games. This BB game is a game in which a general game and a transition to an RB game can be made under certain conditions during the general game, and the general game and the RB game are reached until a predetermined number of game media payouts is reached. It is a game that can be repeated.

In the control process described below, the slot machine 10 is activated in advance, and variables used in the main control circuit 100 and the sub control circuit 200 described above are initialized to predetermined values and are in steady operation. Shall.

<Description of main routine>
First, the control process of the main routine will be described with reference to the flowchart of FIG. In this main routine, a control process when a game is performed once, in which one step from when a player inserts a game medium until a plurality of reels displaying a plurality of symbols is rotated and stopped is performed once. Indicates.
First, it is determined whether or not the value of the parameter NRP is greater than 0 (step S11). Here, NRP is a parameter that determines whether or not to replay, and is set so that replay is performed when it is greater than 0, and replay is not performed when it is 0 or less. Further, as shown in step S167 of FIG. 12, when the re-gamer is won and won, 1 is input as the value of NRP.

  If it is determined in step 11 that the value of NRP is 0 or less (NO), it is determined that no re-game is performed, and then it is determined whether or not a game medium has been inserted (step). S12). If it is determined in this determination that a game medium has been inserted (YES), the process proceeds to step S15, and the inserted number counted by the game medium counter installed below the game medium insertion port 38 is detected as the number of bets. (Step S15). However, when the number of game media exceeding the specified number (three in this embodiment) is inserted, the game media exceeding the specified number is stored in the RAM 110 as the number of credits.

  If it is determined in step S12 that no game medium is inserted (NO), the process proceeds to step S13 to determine whether there is a credited game medium (step S13). If it is determined in this determination that there is no credited game medium (NO), the process returns to step S12 again, and the determination processes in steps S12 and S13 are repeated.

  If it is determined in step S13 that there is a credited game medium (YES), it is next determined whether or not a bet operation signal has been received (step S14). This bet operation signal is transmitted when the player operates any one of the bet switches 32, 34 and 36. When it is determined that the bet operation signal has not been received (NO), the process returns to step S12 again, and the determination process from step S12 to step S14 is repeatedly executed. If it is determined in step S14 that a bet signal has been received (YES), the number of bets is detected from the received bet operation signal (step S15). In either case of inserting a game medium or using a credited game medium, the detected bet number is stored in the RAM 110 as a new bet number, and when using a credited game medium, A process of subtracting the number of credits of the game medium by the number of detected bets is performed (step S16), and the process proceeds to step S18.

  If it is determined in step S11 that the value of NRP is greater than 0 and the game is in the replaying state (YES), 0 is input to the value of NRP to cancel the replaying state (step S17), and step S12. Without performing the process of step S16, the same bet number as the bet number in the previous game is set, and the process proceeds to step S18. That is, when it is determined that the game is in the re-gaming state, the game can be performed without newly inserting a game medium or consuming the credited game medium. In this embodiment, the bet number in the replay is set to the same bet number as in the previous game, but it is also possible to set a bet number different from the bet number in the previous game. .

Thus, the game start state is set, and in step S18, a role lottery processing subroutine is performed (step S18). In this combination lottery processing subroutine, combination lottery processing by the combination lottery means 410 is performed, and flag-on processing for turning on the RB flag, the BB flag, the replay flag, and the general combination flag is performed according to the winning combination. Details of this subroutine will be described later with reference to the flowcharts of FIGS. 6, 7, and 13 to 17.
Subsequent to the role lottery processing subroutine (step S18), on the basis of the result of the role lottery, the reel variation and stop subroutine (step S19) for performing control processing relating to the movement of the reels that are stopped after the reels 40L, 40C, 40R are rotated. ) Is performed. This reel fluctuation / stop subroutine is performed by the reel control means 440, and details of this subroutine will be described later with reference to the flowchart of FIG.

Next, after the reels are stopped by the reel fluctuation / stop subroutine, a winning symbol determination is performed, and based on the determination result, a winning determination and flag off processing subroutine (step S20) for performing flag-off processing is performed. Details of this subroutine will be described later with reference to the flowcharts of FIGS.
Then, a payout process (step S21) for paying out a predetermined number of game media corresponding to the winning game based on the winning lottery and winning symbol determination is performed. In the payout process, it is possible to actually pay out the game media from the game media payout outlet 62, or to credit a predetermined number of game media instead of paying out.

  One game is completed by the control process as described above. By repeating the control process shown in this main routine, the player can play a plurality of times.

<Description of role lottery processing subroutine>
Next, the role lottery processing subroutine performed in step S18 of the main routine will be described in detail with reference to the flowcharts shown in FIG. 6, FIG. 7, and FIGS.
In FIG. 6, first, it is determined whether or not a start switch ON signal has been received (step S31). The start switch ON signal is a signal transmitted by the operation means 300 when the player operates the start switch 50. Based on this signal, the reel control means 440 performs control for starting the rotation of the reel. This is performed (see step S63 in FIG. 8).
If it is determined that the start switch ON signal is not received (NO), the determination process in step S31 is repeated. In other words, the player waits for the game to start until the player operates the start switch 50.

  If it is determined in step S31 that the start switch ON signal has been received (YES), it is next determined whether or not the value of the parameter NRB is greater than 0 (step S32). Here, the NRB is a parameter that determines whether or not to play an RB game, and is set so as to play an RB game when it is larger than 0, and not play an RB game when it is less than 0. Further, as shown in step S125 of FIG. 11 and step S164 of FIG. 12, when the RB combination is won and won, 1 is input as the NRB value.

If it is determined in step S32 that the NRB value is greater than 0 (YES), the RB lottery table stored in the ROM 108 is read (step S33), and the process proceeds to step S37. Here, FIG. 19 shows an example of the RB lottery table.
Here, in the lottery table, probability data DATA (J) determined according to the winning probability is set for each combination and out of play. J indicates the determination order. In addition, when all the probability data set for each combination and out of combination are added, the total number N of random numbers generated by the random number generator 112 is matched. Therefore, the value obtained by dividing the probability data set for each combination and out of the game by the total number N of random numbers is the winning probability in the combination lottery (see the right column in FIG. 19). In the present embodiment, the random number generator 112 generates integers increasing by 1 from 0 to 65,535 as random numbers, and the total number N of random numbers is 65,536.
The determination of the determination order J, which is the order in which the probability data is used in the lottery determination, will be described later with reference to FIGS. The detailed description of the lottery determination process performed using the probability data DATA (J) corresponding to the determined determination order J will be described later with reference to FIGS.

  In the RB lottery table, three types of general combinations of symbol numbers 1 to 3 and a deviation of symbol number 4 are set. For the general combination 1 with the symbol number 1, 819 is set as the value of the probability data DATA (J). In other words, the winning probability in the role lottery is about 1/80 (819 / 65,536), and if the symbol of the left reel is cherry, the symbol of the remaining two reels can be any symbol. It is set to win. For the general combination 2 with the symbol number 2, 63 and 627 are set as the values of the probability data DATA (J). In other words, the winning probability in the role lottery is about 1 / 1.03 (63, 627/65, 536), and is set to win when the three reels have the same bell symbol. Therefore, during the RB game, the possibility of winning the general combination 2 in the combination lottery is very high. Moreover, 655 is set as the value of the probability data DATA (J) for the general combination 3 of the symbol number 3. In other words, the winning probability in the role lottery is about 1/100 (655/65, 536), and is set to win when the three reels have the same watermelon symbol. For the deviation of symbol number 4, 435 is set as the value of the probability data DATA (J). In other words, the winning probability in the role lottery is about 1/150 (435/65, 536) and is set to a considerably low value.

If it is determined in step S32 that the NRB value is 0 or less (NO), it is next determined whether or not the parameter NBB value is greater than 0 (step S34). Here, the NBB is a parameter that determines whether or not to play a BB game. When the NBB is larger than 0, the BB game is set and the BB game is not set. Also, as shown in step S164 of FIG. 12, when the BB combination is won and won, 1 is input as the value of NBB.
If it is determined in step S34 that NBB is greater than 0 (YES), the BB operation general lottery table stored in the ROM 108 is read (step S35), and the process proceeds to step S37. Here, an example of the general lottery table during BB operation is shown in FIG.

The general lottery table during BB operation is a lottery table used when the BB game is in progress and not in the RB game. If the BB game is being played and the RB game is being played, the RB lottery table shown in FIG. 19 is used. In the general lottery table at the time of BB operation, three types of general combinations of symbol numbers 1 to 3, an RB combination of symbol number 4 and a deviation of symbol number 5 are set. Here, in comparison with a general lottery table when the BB is not operated (see FIG. 21), which will be described later, the general lottery table when the BB is operated is set to have no re-game combination and BB combination.
The general combination 1 with symbol number 1 has probability data DATA (J) = 819, that is, if the winning probability in the combination lottery is about 1/80 (819 / 65,536) and the symbol on the right reel is cherry, The symbols of the remaining two reels are set so as to win any symbol. The general combination 2 with symbol number 2 has probability data DATA (J) = 13,107, that is, the winning probability in the combination lottery is about 1/5 (13,107 / 65,536). It is set to win when the symbols are aligned.

The general combination 3 with symbol number 3 has probability data DATA (J) = 655, that is, the winning probability in the combination lottery is about 1/100 (655 / 65,536), and the three reels have the same watermelon design. Is set to win. Also, the RB combination of symbol number 4 has probability data DATA (J) = 16,384, that is, the winning probability in the combination lottery is 1/4 (16,384 / 65,536), and replay is performed on the left and middle reels. Are set so that a prize is awarded when the right reel has the same bell design. In the general lottery table (see FIG. 21) when the BB is not operating, which will be described later, the winning probability of the RB role in the role lottery is about 1/600, and during the BB game, the probability of winning the RB role is higher than that in the normal game. It is set high. Further, the deviation of the symbol number 5 is set to probability data DATA (J) = 34,571, that is, the winning probability in the role lottery is set to about 1 / 1.90 (34,571 / 65,536).
Next, if it is determined in step S34 that the value of NBB is 0 or less (NO), then the BB non-operating general lottery table stored in the ROM 108 is read (step S36), and step S37. Proceed to Here, an example of the general lottery table when the BB is not operated is shown in FIG.

  As already explained, the BB non-operating general lottery table is a lottery table used in the normal gaming state, and includes three general roles of symbol numbers 1 to 3, a re-playing role of symbol number 4, and symbol number 5 RB combination, symbol number 6 BB combination, and symbol number 7 are set off. The three general roles of symbol numbers 1 to 3 are the same in the above-described general lottery table during BB operation (see FIG. 20), order J using probability data, probability data DATA (J), and symbol settings. Settings are made. The re-playing role of symbol number 4 has probability data DATA (J) = 8,978, that is, the winning probability in the winning lottery is about 1 / 7.3 (8,978 / 65,536). It is set to win when the replay symbols are complete.

  The RB combination with symbol number 5 has probability data DATA (J) = 109, that is, the winning probability in the combination lottery is about 1/600 (109 / 65,536), and the three reels have the blue 7 symbol. It is set to win a prize, and the possibility of winning the RB combination is lower than that during BB game. For the BB combination of symbol number 6, probability data DATA (J) = 218, that is, the winning probability in the combination lottery is about 1/300 (218 / 65,536), and the three reels have the red 7 symbol. The case is set to win. Further, the deviation of symbol number 7 is set to probability data DATA (J) = 41,650, that is, the winning probability in the role lottery is set to about 1 / 1.57 (41,650 / 65,536).

  As described above, after reading the lottery table corresponding to the gaming state, a random number is acquired and input as the value of the parameter RANSU (step S37). Specifically, one random number is extracted by the random number acquisition means 420 from the random numbers generated by the random number generator 112, and the extracted random value is input as the value of the parameter RANSU. Subsequently, the determination order determination means 430 performs a determination order determination subroutine (step S38) for determining the determination order J, which is the order in which the lottery determination is performed using the probability data, and then the determination order determination is performed by the lottery determination means 430. A lottery determination processing subroutine (step S39) is performed in which the lottery determination is performed using the RANSU value and the probability data in the determination order J determined by the subroutine.

<Description of Determination Order Determination Subroutine>
Next, the determination order determination subroutine shown in step S38 will be described in detail with reference to the flowcharts shown in FIGS.
<Description of First Embodiment of Determination Order Determination Subroutine>
First, the first embodiment of the determination order determination subroutine will be described with reference to FIG. In the present embodiment, a control process for determining one determination order table by lottery from a plurality of determination order tables is performed.
In FIG. 13, first, the determination order table lottery table stored in the ROM 108 is read (step S210). Here, FIG. 22 shows an example of the determination order table lottery table. In FIG. 22, the determination order table lottery table corresponding to the general lottery table when BB is not operated is shown as an example. The determination order table lottery table corresponding to the RB lottery table and the BB operation general lottery table is also set in the same manner.

In the determination order table lottery table of FIG. 22, a determination order table in which a determination order J of 1 to 7 is set for each of the combination of symbol numbers 1 to 7 and deviation is set from Table 1 to Table 9. In addition, the winning probability in the lottery of each table is set to 1/9.
Next, a random number is generated by a desired means, one random number is extracted, and one determination order table is selected from Table 1 to Table 9 by lottery determination based on the acquired random number (Step S212). Here, the random numbers used in the lottery can be random numbers used in the role lottery, hard random numbers using other random number generators, or soft random numbers using software. it can.
Then, based on the selected determination order table, the determination order J is stored in the RAM 110 together with the corresponding combination and deviation (step S214), and this subroutine is terminated.

<Description of Second Embodiment of Determination Order Determination Subroutine>
Next, a second embodiment of the determination order determination subroutine will be described with reference to FIG. In the present embodiment, a random number is generated for each combination and miss, and a control process for determining the order of determination of each combination and miss is performed based on the acquired random number value.
In this subroutine, first, a random number is generated for each combination and deviation, and one random number is extracted (step S220). Next, the determination order J of each combination and out of order is determined in ascending order of the obtained random number value, and stored in the RAM 110 (step S222), and this subroutine is finished. The random number used here may be a hard random number using a random number generator or a soft random number using software.

Next, the contents of the control processing of this subroutine will be described in more detail with reference to FIGS. Here, in order to explain the control processing of this subroutine in an easy-to-understand manner, a simple lottery table shown in FIG. 23 will be used. In FIG. 23, four combinations and outliers of combinations A to C and outage are set, and for each game, random numbers are generated for each of the combinations A through C and out of 1 to obtain and acquire The order of the combination A to the combination C and the judgment order J is determined in ascending order of the random numbers. FIG. 24 shows three cases (case 1 to case 3) in which different determination orders J are determined for the combinations A to C and the outliers according to the acquired random numbers. Note that the random number region to be won in the winning combination lottery when the determination order J shown in case 1 to case 3 is determined will be described later with reference to FIG.
In addition, the determination order J is not limited to the order in which the acquired random number value is small, and the determination order J can be determined in the order of the acquired random number value, or the acquired random number value is an even number. The determination order J can also be determined with priority over the above, or the determination order J can be determined with priority over when the acquired random number value is an odd number. Also, the determination order J can be determined by combining them or performing other operations using the acquired random numbers.

<Description of Third Embodiment of Determination Order Determination Subroutine>
Next, a third embodiment of the determination order determination subroutine will be described with reference to FIG. In the present embodiment, a soft random number is generated, and a control process for determining the order of determination of each combination and outage is performed based on the information of the upper 4 digits of the acquired random number.
In this subroutine, first, a random number is generated using software and a random number of 1 is extracted (step S230). Next, it is determined whether or not the total number of digits that are set (value is 1) among the upper 4 digits of the acquired random number is an even number (step S232). If it is determined in this determination that the total number of digits with bits is an even number (YES), as shown in the order A of the determination order selection table in FIG. The determination order is determined in the direction from the top to the bottom with respect to the combination C and the deviation, and the determined determination order J is stored in the RAM 110 together with the corresponding combination A to the combination C and the deviation (step S234). finish.

If it is determined in step S232 that the total number of digits with bits is not an even number (NO), that is, it is an odd number, as shown in order B of the determination order selection table in FIG. Are determined in order from bottom to top, and the determined determination order J is stored in the RAM 110 together with the corresponding combination A to combination C and out of order (step S1). (S236) This subroutine is terminated. Note that the random number area to be won in the winning combination lottery when the determination order J is determined in the order A or the order B will be described later with reference to FIG.
In contrast to the above-described embodiment, when it is determined that the total number of digits with bits set is an even number, the order B in the determination order selection table of FIG. 26 is selected, and the total number of digits with bits set is It can be set to select the order A of the determination order selection table in FIG.
Further, as in the present embodiment, the present invention is not limited to the case where the upper 4 digits of the acquired random number are used. Other arbitrary digits can be used, and all digits can be used. You can also. In addition, for example, it may be possible to associate each digit of a random number with each role and deviation, and to preferentially determine the determination order of the role and deviation corresponding to the digit where the bit stands, or conversely, the bit It is also conceivable to preferentially determine the combination order and the judgment order of the deviation corresponding to the digit where no is standing. Further, for example, it is possible to generate a random number for each combination and out of order to obtain one random number, and to determine the determination order J based on information on the bits of the random number corresponding to each combination and out of combination.

<Description of lottery determination processing subroutine>
Next, using the flowcharts shown in FIGS. 16 and 17, the lottery determination processing subroutine performed in step S39 will be described in detail following the determination order determination subroutine in step 38.

<Description of the first embodiment of the lottery determination subroutine (in the case of the addition method)>
First, the first embodiment of the lottery determination subroutine for performing lottery determination by the addition method will be described in detail with reference to FIG. In addition, in order to explain the control processing of this subroutine in an easy-to-understand manner, an example in which an addition-type lottery determination is performed in the determination order J shown in Case 1 to Case 3 of FIG. 24 using the lottery table shown in FIG. I will explain.
In the lottery table shown in FIG. 23, the four combinations of the combination A, combination B, combination C and disparity are set. The combination A is set as 3 as the value of the probability data DATA (J), and the combination B is the probability data. 4 is set as the value of DATA (J), 2 is set as the value of the probability data DATA (J) for the combination C, and 5 is set as the probability data DATA (J) for the outage.
In the lottery table as described above, when N = 14 (N = m2−n1 + 1) increasing integers from the numerical value n1 = 10 to the numerical value n2 = 23 are used as random numbers (that is, the random number update number K) = 1) will be described. In this case, the value of MAXRANSU, which is the maximum random number, is 23.

First, the case of determination order J in case 1 in FIG. 24 will be described as an example. Specifically, in the case 1, the combination order J for the combination B = 1, the determination order J for the disparity J = 2, the determination order J for the combination A = 3, and the determination order J for the combination C = 4. is there.
In the case of using the probability data and the determination order J (Case 1) as described above, FIG. 25 schematically shows a random number area determined as winning by the addition-type lottery determination with respect to each combination and deviation. Shown in (a).

  In the flowchart of FIG. 16, first, 1 is input as the value of the determination order J (step S300). That is, in case 1, the lottery determination process is performed from the combination B with the determination order J = 1. Then, the value of RANSU (see step S37 in FIG. 6) stored in the RAM 110 is read and input as an initial value of the parameter KASANCHI (step S302). Next, an operation is performed to add a value obtained by multiplying the value of KASANCHI by the role of the judgment order J or the probability data DATA (J) out of place and the update value K of the random number, and the operation value (added value) is added to the new KASANCHI. Is input as a value (step S304).

  In this case, for example, in the combination B (DATA (1) = 4) in the determination order J = 1, if the extracted random number value is any one of 20, 21, 22, or 23, it is calculated in step S304. The new KASANCHI value is 20 + 4 (= DATA (1)) × 1 (= K) = 24, or 21 + 4 (= DATA (1)) × 1 (= K) = 25, or 22 + 4 (= DATA (1 )) × 1 (= K) = 26, or 23 + 4 (= DATA (1)) × 1 (= K) = 27. On the other hand, if the extracted random number value is 19 or less, the new KASANCHI value calculated in step S304 is 19 + 4 (= DATA (1)) × 1 (= K) = 23 or less.

Next, it is determined whether or not the value of KASANCHI calculated in step S304 is larger than the value of MAXRANSU (step S306). In this determination, if the extracted random number value is 20, 21, 22, or 23, the KASANCHI value (24, 25, 26, or 27) calculated in step S304 is in any case. It is determined that the value is larger than the value of MAXRANSU (= 23) (YES), it is determined that the combination B with the determination order J = 1 has been won (step S310), and this subroutine is terminated. That is, according to the addition-type lottery determination, when the extracted random number value is 20, 21, 22, or 23, it is determined that the winning combination B having the determination order J = 1 is won. Such a random number area in which the combination B with the determination order J = 1 is won is schematically shown in FIG.
On the other hand, if it is determined in step S306 that the extracted random number value is 19 or less, it is determined that the value of KASANCHI (23, 22...) Is equal to or less than the value of MAXRANSU (= 23) (NO). Then, a control process for adding 1 to the value of the determination order J using the probability data is performed (step S308), and the process returns to the control process of step S304.

Next, a value obtained by multiplying the probability data DATA (J) and the random number update value K by KASANCHI is input as a new KASANCHI value for the deviation of the determination order J = 2 (step S304).
In this case, if the extracted random number value is any one of 15, 16, 17, 18 or 19 in the judgment order J = 2 deviation (DATA (2) = 5), the calculation is performed in step S304. The previous value of KASANCHI is 15 + 4 (= DATA (1)) × 1 (= K) = 19, or 16 + 4 (= DATA (1)) × 1 (= K) = 20, or 17 + 4 (= DATA (1) ) × 1 (= K) = 21, or 18 + 4 (= DATA (1)) × 1 (= K) = 22, or 19 + 4 (= DATA (1)) × 1 (= K) = 23. Therefore, the value of KASANCHI newly calculated in step S304 is 19 + 5 (= DATA (2)) × 1 (= K) = 24, or 20 + 5 (= DATA (2)) × 1 (= K) = 25, Or 21 + 5 (= DATA (2)) × 1 (= K) = 26, or 22 + 5 (= DATA (2)) × 1 (= K) = 27, or 23 + 5 (= DATA (2)) × 1 (= K ) = 28.
On the other hand, if the value of the extracted random number is 14 or less, the value of KASANCHI before calculation in step S304 is 14 + 4 (= DATA (1)) × 1 (= K) = 18 or less, and in step S304. The calculated new value of KASANCHI is 18 + 5 (= DATA (2)) × 1 (= K) = 23 or less.

Accordingly, in the next determination processing in step S304, if the extracted random number value is 15, 16, 17, 18 or 19, the KASANCHI value (24, 25, 26) is used in any case. 27, 28) is determined to be greater than the value of MAXRANSU (= 23) (YES), it is determined that the order is J = 2 (step S310), and this subroutine is terminated. That is, according to the addition-type lottery determination, when the extracted random number value is 15, 16, 17, 18 or 19, it is determined that the determination order is J = 2. Such a random number region that is out of the judgment order J = 2 is schematically shown in FIG.
If the extracted random number value is 14 or less, the same control process is repeated, and if the extracted random number is 12, 13 or 14, it is determined that the combination A with the determination order J = 3 is won. When the extracted random number is 11 or less (that is, 10 or 11), it is determined that the winning combination C having the determination order J = 4 is won. FIG. 25 (a) schematically shows a random number area in which each winning combination and disparity in the case 1 is won by the above-described addition-type lottery determination.

Similarly, in the case of the determination order J of case 2, specifically, the determination order J of the combination A = 1, the determination order J of the combination C = 2, the determination order J of the deviation J = 3, In the case of B determination order J = 4 (see FIG. 24), by performing addition-type lottery determination similar to that described above, random number areas in which each winning combination and out of winning are determined are determined. This is schematically shown in FIG.
Similarly, in the case of the judgment order J of case 3, specifically, the judgment order J of the combination C = 1, the judgment order J of the combination A = 2, and the judgment order J of the combination B = 3, In the case where the judgment order J is 4 (see FIG. 24), by performing the same addition-type lottery judgment as described above, the random number areas in which the winning combination and the misplacement are won are determined. This is schematically shown in FIG.
Note that the lottery determination process based on the addition-type lottery determination as described above is not limited to the case where an integer with an update value K = 1 is used as a random number, and an integer in which the update value K increases at a constant interval of 2 or more is used as a random number. The same applies when used.

<Comparison of Case 1 to Case 3>
As is clear from FIGS. 25 (a) to 25 (c), when performing addition-type lottery determination, the random number area in which each winning combination and winning is selected is determined in the direction from the maximum value to the minimum value of the random number. They are arranged in the order of order J (= 1 to 4). Therefore, as in the case 1 to case 3, when the judgment order of the winning combination and the deviation is changed in each case, the random number area in which each winning combination and the winning decision is won is also changed. Even if the is taken out, the winning combination or losing will be different. Therefore, even if a situation occurs in which specific random numbers are biased and taken out due to human activities, the determination order of each combination and out of play for each game can be made by using the determination order determination subroutine shown in FIG. It can be changed, and it can be effectively prevented that a specific role is biased. In the above-described embodiment, the determination order of each combination and disparity is determined for each game. However, the slot machine according to the present invention is not limited to this, for example, each time a plurality of games are digested. The determination order can also be determined, the determination order can be determined a plurality of times in one game, and the determination order can be determined at any other timing.
In addition, even if the determination order of each combination and loss is the same, even if the same random number is taken out by using the subtractive lottery determination described later, the winning combination or loss will be different. You can also

<Description of the second embodiment of the lottery determination subroutine (in the case of the subtraction method)>
Next, a detailed description will be given of a second embodiment of a lottery determination subroutine for performing lottery determination by a subtraction method. In the lottery determination subroutine in step S39 in FIG. 6, whether to use the first embodiment that is addition-type lottery determination or the second embodiment that is subtraction-type lottery determination is arbitrary for each game. You can choose by method. For example, it is desirable to use a method in which it is difficult for a person who performs an artificial action to recognize, such as using a random number.

In order to explain the control processing of this subroutine in an easy-to-understand manner, here, a case where subtraction-type lottery determination is performed in the order of judgment A of order A or order B of FIG. 26 using the lottery table shown in FIG. Take and explain.
Similarly to the description of the addition method lottery determination subroutine described above, in the lottery table shown in FIG. 23, N = 14 (N = m2−n1 + 1) integers increasing by 1 from the numerical value n1 = 10 to the numerical value n2 = 23. A case where the random number is used as a random number (that is, a case where the random number update number K = 1) will be described. In this case, the value of MINRANSU, which is the minimum random number, is 10.

First, the case of order A in FIG. 26 will be described as an example. Specifically, in the order A, the judgment order J is determined in order from the top to the bottom for the hands A to C and the disparity arranged vertically, and the judgment order J of the hand A is J = 1. The judgment order J = 2, the judgment order J for the combination C = 3, and the judgment order J for loss is 4.
In the case of using the probability data and the determination order J (order A) as described above, FIG. 27 schematically shows a random number area determined to be a win by subtraction-type lottery determination for each combination and outage. Shown in (a).

  In the flowchart of FIG. 17, first, 1 is input as the value of the determination order J (step S320). That is, the lottery determination process is performed from the combination A having the determination order J = 1 in the order A in FIG. Then, the value of RANSU (see step S37 in FIG. 6) stored in the RAM 110 is read and input as the initial value of the parameter GENSANCHI (step S322). Then, an operation of subtracting a value obtained by multiplying the GENSANCHI value by the probability data DATA (J) and the update value K of the random number is performed, and the operation value (subtraction value) is input as a new GENSANCHI value (step S324). .

  In this case, for example, in the combination A (DATA (1) = 3) with the determination order J = 1, if the extracted random number value is any one of 10, 11, or 12, it is calculated in step S324. The new GENSANCHI value is 10-3 (= DATA (1)) × 1 (= K) = 7, or 11-3 (= DATA (1)) × 1 (= K) = 8, or 12−. 3 (= DATA (1)) × 1 (= K) = 9. On the other hand, if the extracted random number value is 13 or more, the new GENSANCHI value calculated in step S324 is 13-3 (= DATA (1)) × 1 (= K) = 10 or more. .

Next, it is determined whether or not the value of GENSANCHI calculated in step S324 is smaller than the value of MINRANSU (step S326). In this determination, if the extracted random number value is 10, 11 or 12, the GENSANCHI value (7, 8 or 9) calculated in step S324 is MINRANSU (= 10) in any case. ) Is smaller than (YES), it is determined that the combination A with the determination order J = 1 has been won (step S330), and this subroutine is terminated. That is, according to the subtraction type lottery determination, when the extracted random number value is 10, 11 or 12, it is determined that the winning combination A with the determination order J = 1 is won. Such a random number area in which the combination A with the determination order J = 1 is won is schematically shown in FIG.
On the other hand, if it is determined in step S326 that the extracted random number value is 13 or more, it is determined that the GENSANCHI value (10, 11,...) Is MINRANSU value (= 10) or more (NO). Then, a control process for adding 1 to the value of the order J is performed (step S328), and the process returns to the control process of step S324.

Next, a value obtained by subtracting the value obtained by multiplying DATA (J) and the random number update value K from the GENSANCHI value for the combination B having the determination order J = 2 is input as a new GENSANCHI value (step S324). .
In this case, if the extracted random number value is any one of 13, 14, 15 or 16 in the combination B (DATA (2) = 4) in the determination order J = 2, it is calculated in step S324. The value of GENSANCHI before the operation is 13-3 (= DATA (1)) × 1 (= K) = 10, or 14-3 (= DATA (1)) × 1 (= K) = 11, or 15− 3 (= DATA (1)) × 1 (= K) = 12, or 16-3 (= DATA (1)) × 1 (= K) = 13. Therefore, the value of GENSANCHI newly calculated in step S324 is 10-4 (= DATA (2)) × 1 (= K) = 6, or 11-4 (= DATA (2)) × 1 (= K. ) = 7, or 12-4 (= DATA (2)) × 1 (= K) = 8, or 13-4 (= DATA (2)) × 1 (= K) = 9.
On the other hand, if the extracted random number value is 17 or more, the GENSANCHI value before calculation in step S324 is 17-3 (= DATA (1)) × 1 (= K) = 14 or more. The new GENSANCHI value calculated in step S324 is 14−4 (= DATA (2)) × 1 (= K) = 10 or more.

Therefore, in the next determination process in step S326, if the extracted random number value is 13, 14, 15 or 16, the GENSANCHI value (6, 7, 8, 9) is used in any case. ) Is smaller than the MINRANSU value (= 10) (YES), it is determined that the combination B with the determination order J = 2 has been won (step S330), and this subroutine is terminated. That is, according to the subtraction type lottery determination, when the extracted random number value is 13, 14, 15 or 16, it is determined that the combination B with the determination order J = 2 has been won. FIG. 27A schematically shows a random number area in which the combination B having the determination order J = 2 is won.
If the extracted random number value is 17 or more, the same control process is repeated, and if the extracted random number is 17 or 18, it is determined that the combination C with the determination order J = 3 is won. However, when the extracted random number is 19 or more (that is, 19, 20, 21, 22 or 23), it is determined that there is a deviation. FIG. 27 (a) schematically shows a random number area in which each winning combination and disparity is won by the subtraction type lottery determination as described above.

On the other hand, in the order B (see FIG. 26), the judgment order J is determined in order from the bottom to the top with respect to the hands A to C and the outliers arranged vertically, and the judgment order J is J = 1. The determination order J of C = 2, the determination order J of the combination B = 3, and the determination order J of the combination A = 4. Even in the case of this order B, by performing the same subtraction type lottery determination as described above, random number areas in which each winning combination and out of winning are determined are determined, and these areas are schematically shown in FIG. Indicated.
Note that the lottery determination process based on the subtraction type lottery determination as described above is not limited to the case where the integer of the update value K = 1 is used as a random number, and the update value K is 2 or more as in the above-described addition type lottery determination subroutine. The present invention can also be applied to the case where integers increasing at regular intervals are used for random numbers.

<Comparison between order A and order B>
As is clear from FIG. 27, when subtractive lottery determination is performed, the random number area in which each winning combination and out of winning is determined, the determination order J (= 1 to 4) in the direction from the minimum value to the maximum value of the random number. Line up in the order. Therefore, in the case of order A, the value of the random number that is won is increased in the order of combination A, combination B, combination C, out of order, and in the case of order B, out of combination, combination C, combination B, combination A The value of the random number won in the order of.
As described above, when the judgment order of the combination and out of game changes for each game, the random number area where each combination and out of winning is also changed, and the same random number is temporarily extracted in the lottery process. Even in this case, the winning combination or disparity will be different. Therefore, even if a situation occurs in which specific random numbers are biased and taken out by human action, for example, using the determination order determination subroutine shown in FIG. J can be changed, and it is possible to effectively prevent a specific role from being won in a biased manner. In the above-described embodiment, the determination order of each combination and disparity is determined for each game. However, the slot machine according to the present invention is not limited to this, for example, each time a plurality of games are digested. The determination order can also be determined, the determination order can be determined a plurality of times in one game, and the determination order can be determined at any other timing.
In addition, even if the order of determination of each hand and outlier is the same, when using the above-described addition type lottery determination, the order in which the random numbers are arranged from the minimum value to the maximum value is reversed. Even if it is taken out, it is possible to make the winning combination or disparity different.

  As described above, the lottery determination subroutine has been described using the lottery table in FIG. 23 and the determination order J shown in FIGS. 24 and 26. In the lottery determination subroutine in step S39 in FIG. To 65,535 and 65,536 random numbers and the lottery table shown in FIGS.

<Description of role lottery monitoring subroutine>
In the slot machine according to the present invention, separately from the main routine of FIG. 5, the role lottery monitoring unit 460 activates a role lottery monitoring subroutine for each game, and performs a control process for monitoring the status of the role lottery. Yes. Here, a detailed description of the role lottery monitoring subroutine will be given using the flowchart of FIG.
In the slot machine according to the present invention, for a predetermined number of finished games, the determination order J determined by the determination order determination subroutine and the result of the lottery determination determined by the lottery determination subroutine can be stored and their history can be referred to. It is like that.

  First, when the winning lottery monitoring means 460 receives the determination order J determined in the game being executed and the information signal of the result of the winning lottery, the status of the winning lottery is determined based on the received information and past history data. A control process for monitoring is performed. It is determined whether or not the same determination order J has been determined continuously in M games including the current game (step S400). In this determination, if it is determined that the same determination order J has been determined continuously in M games (YES), the process proceeds to step S420, an alarm signal is transmitted (step S420), and this subroutine is terminated. To do.

If it is determined in step S400 that the same determination order J has not been determined continuously for M games (NO), the next game is continued for N games including the current game. It is then determined whether or not the same combination is won (step S410). In this determination, if it is determined that the same combination has been won continuously in N games (YES), the process proceeds to step S420, an alarm signal is transmitted (step S420), and this subroutine is terminated. If it is determined in step S410 that the same combination has not been won consecutively in N games (NO), this subroutine is terminated as it is.
Here, an arbitrary value can be set for each of the M times and N times of games, which is a criterion for whether or not to send an alarm signal. In the above-described embodiment, 4 is set as the value of M, and 6 is set as the value of N.

Here, the transmission of the alarm signal in step S420 will be described in more detail. The role lottery monitoring means 460 transmits an alarm signal to the sub control circuit 200, and the sub control circuit 200 generates a voice based on the received alarm signal. Alarm sound data is transmitted from the control means 530 to the speaker drive circuit 222, and an alarm sound is generated from the speaker 64. As this alarm sound, for example, a buzzer sound, a siren sound, or the like can be considered.
Further, the sub-control circuit 200 transmits predetermined image data from the image control means 510 to the display drive circuit 220 based on the alarm signal, and displays an image notifying that an abnormal situation has occurred on the display device 70. To do. As an image for notifying such an abnormal situation, it is conceivable that the entire screen is made a red color image or the entire screen is blinked. In addition to notifying the occurrence of an abnormal situation by sound or image, it is also conceivable to perform control processing related to game stoppage such as insertion of a game medium or not accepting a start operation. In the above-described embodiment, the control process for notifying the abnormal situation is performed by the sub-control circuit 200. However, the present invention is not limited to this, and can be performed by the main control circuit 100. Control processing for notifying an abnormal situation by the monitoring means 460 can also be performed.

<Description of lottery determination processing subroutine (continued)>
Returning to the description of the lottery determination process subroutine again, after the lottery determination process subroutine in step S39 is completed, the process proceeds to FIG. 7 to determine whether or not the RB combination is won as a result of the combination lottery determination (step S40). ). If it is determined that the RB combination is won (YES), the RB combination flag is turned on and stored in the RAM 110 (step S41), and the process proceeds to step S49.

  If it is determined in step S40 that the RB combination has not been won (NO), it is next determined whether or not the BB combination has been won (step S42). If it is determined in this determination that the winning combination BB has been won (YES), the winning combination flag is turned on and stored in the RAM 110 (step S43), and the process proceeds to step S49.

If it is determined in step S42 that the BB combination is not won (NO), it is next determined whether or not the re-game combination is won (step S44). In this determination, if it is determined that the re-gamer is won by the role lottery (YES), the re-game flag is turned on and stored in the RAM 110 (step S45), and the process proceeds to step S49.
If it is determined in step S44 that the re-playing combination is not won (NO), it is next determined whether or not the general combination is won (step S46). In this determination, if it is determined that the general combination is won by the combination lottery (YES), the general combination flag is turned on and stored in the RAM 110 (step S47), and the process proceeds to step S49.

If it is determined in step S46 that the general combination is not won (NO), it is determined that the result of the combination lottery determination is out of order, and predetermined control processing at the time of out is performed (step S48). ), Go to step S49.
After performing a series of processes related to flag-on as described above, in step 49, the symbol number and control symbol data corresponding to the winning combination in the winning lottery are read from the ROM 108 and used for the reel fluctuation and stop subroutine described later. This data is stored in the RAM 110. The combination lottery processing subroutine is thus completed.

<Explanation of reel fluctuation / stop subroutine>
Next, in the main routine of FIG. 5, when the above-described combination lottery processing subroutine (step S18) is completed, a reel fluctuation and stop subroutine (step S19) is then performed. Next, the reel fluctuation / stop subroutine will be described in detail with reference to the flowchart shown in FIG.
First, the symbol number and control symbol data stored in step S49 of FIG. 7 are read (step S61). Then, it is determined whether or not a predetermined shortest time has elapsed (step S62). If it is determined in this determination that the shortest time has not elapsed (NO), the determination process in step S62 is repeatedly executed. That is, the rotation of the reel, which is the next process, cannot be started until the shortest time has elapsed. By this control, the number of games played in a certain time is controlled to be within a predetermined number.

If it is determined in step S62 that the shortest time has elapsed (YES), the start switch ON signal has already been received (see step S32 in FIG. 6). Transmission to the drive circuit 114 starts rotation of the motors 80L, 80C, 80R, and rotates the reels 40L, 40C, 40R (step S63).
Next, it is determined whether or not the reel that has started rotating is rotating at a constant speed (step S64). If it is determined in this determination that the reel has not yet rotated at a constant speed (NO), the determination process in step S64 is repeated. That is, the reel stop control, which is the next step, cannot be performed until the rotation of the reel reaches a constant speed.

If it is determined in step S64 that the reel has been rotated at a constant speed (YES), it is next determined whether a reel stop signal has been received (step S65). Here, the reel stop signal is a signal transmitted by the operation means 300 when the player pushes any one of the stop switches 52L, 52C, 52R.
If it is determined in step S65 that the reel stop operation detection signal has been received (YES), the reel control means 440 controls the reel symbol combination control (stop control) corresponding to the stop switch that has transmitted the operation detection signal. ) (Step S66), the process proceeds to step S67.

  More specifically, when the stop switch 52L for the left reel is pushed, the reel control means 440 performs stop control in step S66 for the motor 80L that rotates the left reel 40L. Similarly, when the stop switch 52C for the middle reel is pushed, the stop control in step S66 is performed for the motor 80C that rotates the middle reel 40C, and the stop switch 52R for the right reel is pushed. In this case, the stop control in step S66 is performed for the motor 80R that rotates the right reel 40R.

  The symbol combination control (stop control) is based on the symbol number and control symbol data read out in step S61, with the frame when the reel stop signal is received as the first frame, sliding the reel up to the fifth frame, Within the range, stop control of the motor is performed so as to stop or not stop the predetermined symbol.

If it is determined in step S65 that the reel stop signal has not been received (NO), the control proceeds to step S67 without performing control related to the stop. In step S67, it is determined whether or not all reels are stopped (step S67).
If it is determined in this determination that all the reels are not stopped (NO), it is next determined whether or not the time limit has elapsed (step S68). If it is determined in this determination that the time limit has not been reached (NO), the process returns to step S65 again, and the processing from step S65 to step S68 is repeated. As described above, until all the reels stop or until the time limit elapses, the process of performing symbol combination control (stop control) of the corresponding reels is repeated every time the reel stop signal is received.

If it is determined in step S68 that the time limit has elapsed (YES), automatic symbol stop control is performed for reels that are still rotating to stop all reels (step S69), and this subroutine is executed. finish. In this automatic symbol stop control, it is possible to shift the stop position of a maximum of five symbols (five frames) with the frame at the time limit elapse as the first frame, and the winning symbol is always within that range. Stop control is performed so that they are not aligned.
Next, returning to the determination of step S67, if it is determined that all the reels are stopped (YES), this subroutine is terminated as it is.

<Explanation of Winning Determination and Flag Off Processing Subroutine>
Next, in the main routine of FIG. 5, when the reel fluctuation / stop subroutine (step S19) is completed, a winning determination and flag-off process subroutine (step S20) is performed. The winning determination and flag off processing subroutine will be described in detail with reference to the flowchart shown in FIG.
First, it is determined whether or not the game state is that the value of NRB is greater than 0 (whether or not an RB game is being played) (step S91). If it is determined in this determination that the value of NRB is greater than 0 (YES), an RB game processing subroutine (step S92) is performed, and this subroutine is terminated. A detailed description of the RB game processing subroutine will be described later with reference to FIG.

If it is determined in step S91 that the NRB value is 0 or less (NO), it is next determined whether or not the NBB value is greater than 0 (whether or not a BB game is being played). (Step S93). If it is determined in this determination that the NBB is (YES), a BB gaming process subroutine (step S94) is performed, and this subroutine is terminated. A detailed description of the BB game processing subroutine will be described later with reference to FIG.
If it is determined in step S93 that the NBB value is 0 or less (NO), it is next determined whether or not there is a winning combination (step S95). If it is determined that there is a winning combination (YES), a winning combination processing subroutine (step S96) is performed, and this subroutine is terminated. A detailed description of the winning combination processing subroutine will be described later with reference to FIG.

If it is determined in step S95 that there is no winning combination (NO), this subroutine is terminated as it is. Hereinafter, a detailed description of the subroutine shown in steps S92, S94, and S96 will be given.
<Description of processing subroutine during RB game>
First, a detailed description of the RB game processing subroutine (step S92) executed when it is determined in step 91 that the RB game is being performed will be described with reference to the flowchart shown in FIG.
First, a winning symbol determination is made as to whether or not the reel symbol stopped by the reel fluctuation and stop subroutine described above has won a prize (step S101). Next, the game count and the winning count are counted, the game count and winning count data are updated, and the updated data is stored in the RAM 110 (step S102). These data are used as the RB game end condition. When the number of games or the number of winnings reaches a predetermined number, the RB game is ended.

Next, it is determined whether or not a BB game is being played (step S103). If it is determined in this determination that the BB game is being played (YES), that is, the BB game is being played in the RB game, the payout number is counted to update the payout number data, and the updated data is stored in the RAM 110. (Step S104). This data is used as a BB game end condition. When the payout number reaches a predetermined number, the BB game is ended.
Next, it is determined whether or not the BB game end condition is achieved (step S105). In this determination, if it is determined that the BB game end condition is achieved (YES), 0 is input to the NBB value and the NRB value, that is, the BB gaming state and the RB gaming state are canceled. (Step S106), this subroutine is finished.

  If it is determined in step S105 that the BB end condition is not achieved (NO), it is next determined whether or not the RB end condition is achieved (step S107). In this determination, if it is determined that the RB end condition is achieved (YES), 0 is input as the NRB value to release the RB gaming state (step S108), and this subroutine is ended. However, in this case, since the BB game continues, the process of inputting 0 to the value of NBB is not performed. If it is determined in step 107 that the RB end condition has not been achieved (NO), this subroutine is ended without releasing the RB gaming state.

  Next, returning to the determination in step S103, when it is determined that the BB game is not being played (NO), that is, the RB game is being played in the normal game, it is next determined whether or not the RB end condition is achieved. (Step S109). If it is determined in this determination that the RB end condition is achieved (YES), 0 is input to the value of NRB to release the RB gaming state (step S110), and this subroutine is ended. If it is determined in step S109 that the RB termination condition has not been achieved (NO), this subroutine is terminated without releasing the RB gaming state.

<Description of processing subroutine during BB game>
Next, FIG. 11 shows a detailed explanation of the BB game processing subroutine (see step S94) executed when it is determined in step S93 that the BB game is being played in the winning determination and flag off processing subroutine (see FIG. 9). This will be described with reference to the flowchart shown.
First, a winning symbol determination is made as to whether or not the reel symbol stopped by the reel fluctuation and stop subroutine described above has won a prize (step S121). Next, as a result of the winning symbol determination, it is determined whether or not any winning combination has been won (step S122). If it is determined in this determination that no winning is made (NO), if any flag is on, this flag is turned off (step S123), and the process proceeds to step S128.

If it is determined in step S122 that there is a prize (YES), it is next determined whether or not the RB combination has won (step S124). If it is determined in this determination that the RB combination has won (YES), 1 is input to the NRB value to set the RB gaming state (step S125), and the RB flag is turned off (step S126). The process proceeds to step S128. By inputting 1 to the value of NRB, the RB game is played from the next game. For example, in the determination of step S33 in FIG. 6, it is determined that the RB game is in progress.
If it is determined in step S124 that the RB combination has not won (NO), the general combination flag is turned off (step S127), and the process proceeds to step S128.

Next, in step S128, the payout number is counted, the payout number data is updated, and the updated data is stored in the RAM 110 (step S128). This data is used as a BB game end condition, and when the payout number reaches a predetermined number, the BB game is ended.
Next, it is determined whether or not the BB game end condition has been achieved (step S129). If it is determined in this determination that the BB game end condition has been achieved (YES), 0 is input to the NBB value to release the BB game state (step S130), and this subroutine is ended. If it is determined in step S129 that the BB termination condition is not achieved (NO), the BB gaming state is not canceled and the present subroutine is terminated.

<Explanation of the processing sub-routine at the time of winning>
Next, in the determination and flag-off processing subroutine (see FIG. 9), the detailed explanation of the winning combination processing subroutine (see step S96) executed when it is determined in step S95 that there is a winning combination is shown in the flowchart shown in FIG. To do.
First, a winning symbol determination is made as to whether or not the reel symbol stopped by the reel fluctuation and stop subroutine described above has won a prize (step S161). Next, as a result of the winning symbol determination, it is determined whether or not any winning combination has been won (step S162).

  If it is determined in this determination that a prize has been won (YES), it is next determined whether or not the BB combination or the RB combination has won (step S163). In this determination, if it is determined that the BB combination or RB combination has won (YES), 1 is input to the value of NBB or NRB in accordance with the winning combination, and the winning gaming state (BB or RB) is set. (Step S164). Then, the winning BB or RB flag is turned off (step S165), and this subroutine is terminated. By inputting 1 to the value of NBB or NRB, BB and RB games are performed from the next game. For example, in the determination of step S33 or step 35 in FIG. 6, it is determined that the game is BB or RB game.

  If it is determined in step S163 that neither the BB combination nor the RB combination has been won (NO), it is next determined whether or not the re-game combination has won (step S166). If it is determined in this determination that the re-gamer has won (YES), 1 is input to the value of NRP (step S167). By this process, a re-game is performed in the next game (see step S11 in FIG. 5). Then, the re-game flag is turned off. If the BB and RB flags are on, a flag carry-over process is performed (step S168), and this subroutine is terminated.

If it is determined in step S166 that the re-gamer has not won (NO), the general combination flag is turned off. If the BB and RB flags are on, Carry over processing is performed (step S169), and this subroutine is terminated.
Returning to the determination in step S162, if it is determined that there is no winning (NO), it is next determined whether or not the BB and RB flags are on (step S170). In this determination, if it is determined that the BB and RB flags are turned on (YES), carry-over processing of the BB and RB flags is performed, and the other flags (general combination, replay combination) are turned on. If so, the flag is turned off (step S171), and this subroutine is terminated.

If it is determined in step S170 that the BB and RB flags are not turned on (NO), the flag-on flag (general combination, re-playing combination) is turned off (step S172). Exit the subroutine.
<Description of main routine (continued)>
As described above, the subroutine shown in steps S92, S94, and S96 ends, and the winning determination and flag off processing subroutine shown in FIG. 9 ends. Here, returning to the main routine of FIG. 5, the winning determination and flag-off process subroutine in step S20 is terminated, the payout process is performed in step S21, and this main routine is terminated. Thereby, the control process for performing a game in which one process from the time the symbol fluctuates until it stops is completed.
