Description

  The present invention relates to a gaming machine, a winning determination method for a gaming machine, and a program.

  A gaming machine such as a slot machine is provided with a medal slot so that a player can enjoy a game by inserting a predetermined number of medals. The medals necessary for the game can be borrowed with a medal lending machine provided in the game hall, and the game can be started by inserting it into the medal slot of a desired gaming machine.

The operation of the conventional gaming machine was as follows.
First, when the start switch is operated, the start switch is turned on. In response to this, a lottery process is performed by a winning lottery means inside the gaming machine. Here, when a predetermined combination is won, a winning flag is set. The rotating reel starts to rotate. When the stop switch is operated, the stop switch is turned on. Then, the rotation of the corresponding rotating reel is stopped. After the stop switches corresponding to all the rotating reels are operated, whether or not the winning symbols corresponding to the winning flag are aligned on the effective winning line while the winning flag is established, that is, whether or not the winning is confirmed. Is determined. When it is determined that the winning is confirmed, a medal corresponding to the winning symbol is paid out.

  For example, when the evaluation of the lottery process is out of place, it is set so that the predetermined symbols are not aligned (so-called kicking), and when winning, the predetermined symbols are aligned on the condition that the stop switch is pressed at a predetermined timing. (So-called pull-in). In other words, only when winning in the lottery process, medals are paid out by winning a winning pattern under a predetermined condition, but when not winning, medals are paid out regardless of how the stop switch is operated. There is no. This is to keep the medal payout at a certain probability. In order to realize this, a random number generator is used in the lottery process.

  A random number generator of a gaming machine generates a random number using a counter, for example. The random numbers generated in this case have a certain degree of regularity, and therefore have a predictable aspect. The possibility that the player could make the lottery probability over a predetermined value by skillfully operating the start switch could not be denied. For example, it has been considered that the same random number is repeatedly obtained by adjusting the timing of pressing the start switch.

  In order to avoid such a situation, it may be considered that the time from when the start switch is turned on to when the lottery process is performed by the winning lottery means inside the gaming machine is given fluctuation. When a random number is actually acquired, a latch timing signal is used. If the generation time of this signal is irregular, it becomes difficult to predict what random number will be generated.

  Therefore, according to the present invention, by generating the fluctuation, a specific random number cannot be obtained even by operating a start switch, and a prize determination of a gaming machine and a gaming machine in which a specific player is not advantageous in terms of a lottery probability An object is to provide a method and a program.

Embodiment 1 of the Invention
A gaming machine according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of a gaming machine (slot machine) according to an embodiment of the invention.
A player who wants to enjoy a game with the slot machine 10 first borrows a medal as a game medium from a medal lending machine (not shown) or the like, and inserts a medal directly into the medal insertion slot 100 of the medal insertion device. The medal slot 100 is provided at a substantially central position in front of the slot machine 10.

  The slot machine 10 has a square box-shaped housing 11. A square window-like display window 12 facing the player side is formed at the center and upper part of the casing 11. A symbol display window 13 through which the symbols 61 of the three rotary reels 40 can be seen is formed at the center of the display window 12 at the center. The bet switch 16 is a switch located below the rotary reel 40 and reduces the number of stored medals to replace medal insertion. The settlement switch 17 is a switch located obliquely below the rotating reel, and pays out the stored inserted medal. The start switch 30 is a lever positioned obliquely below the rotary reel 40 and starts driving the reel unit 60 on condition that a game medal is inserted or the bet switch 16 is inserted. The stop switch 50 is for stopping the driving of the reel unit 60. The reel unit 60 is composed of three rotating reels 40. Each rotating reel 40 includes a rotating drum made of a synthetic resin and a tape-like reel tape 42 attached around the rotating drum. On the outer peripheral surface of the reel tape 42, a plurality of (for example, 21) symbols 61 are displayed. Reference numeral 62 denotes a liquid crystal display unit for performing various effects.

  Inside the slot machine 10, although not shown, a control device for controlling the entire operation of the slot machine 10 is incorporated. Although not shown, the control device is configured around a CPU and includes a ROM, a RAM, an I / O, and the like. Then, the CPU operates by reading a program stored in the ROM, and controls the rotation and stop of the rotary reel 40 based on the operation of the start switch 30 and the stop switch 50, and also controls the display of lamps, speakers, and the like.

  As described above, the start switch 30 is a lever that is positioned obliquely below the rotary reel 40. The start switch 30 is subject to the insertion of a game medal or the bet switch 16, or from the previous game at the time of “Replay”. This is for starting the driving of the reel unit 60 on condition that the predetermined time elapses.

  The stop switch 50 is for stopping the driving of the reel unit 60 as described above. Specifically, the stop switch 50 includes three switches corresponding to each rotary reel 40, and one stop switch 50 is disposed below each rotary reel 40. The operation of the stop switch 50 corresponding to the rotating reel 40 is set to stop the rotation of the corresponding rotating reel 40.

  When the start switch 30 is operated on the condition that the medal is inserted or the bet switch 16 is inserted, or on the condition that a predetermined time has elapsed from the previous game at the time of “replay”, the reel unit 60 is driven, and the three units The rotating reel 40 starts to rotate. Thereafter, when one of the stop switches 50 is operated, the rotation of the corresponding rotary reel 40 is stopped. When all three stop switches 50 are operated, the rotation of the three rotary reels 40 is stopped. At this time, when a preset symbol 61 is stopped on the effective pay line of the display window 12, a predetermined number of medals are paid out via the hobber unit 65. In addition, you may credit instead of paying out medals.

  When the control device controls the rotation and stop of the rotary reel 40 based on the operation of the start switch 30 and the stop switch 50, the lottery for determining whether or not the winning qualification is obtained based on a predetermined lottery probability. Including a winning lottery means. When the lottery result by the winning lottery means is a win, a winning flag is established, and the winning combination is established on the condition that the combination of the stopped symbols of the rotating reel 40 matches a predetermined winning symbol while the winning flag is established. It is determined so that the player is given a medal or a special game.

  FIG. 2 is a block diagram of the winning lottery means. The winning lottery means is included in the control device, and specifically, the device is realized by the above CPU executing a program stored in the ROM of the main board and / or by hardware. As shown in FIG. 2, the winning lottery means includes a fluctuation generator 1, a random number generator 2, a random number extractor 3, a determination unit 4, and a winning determination table 5. The configuration of the winning lottery means is not limited to that shown in FIG.

  The fluctuation generator 1 receives a signal from the start switch 30, adds fluctuation to the signal, and outputs it. Details of this will be described later.

  The random number generator 2 generates a random number for winning lottery within a predetermined area. For example, an arbitrary numerical value is generated with a predetermined probability in a range of 0 to a certain number.

  The random number extractor 3 extracts the random number generated by the random number generator 2 based on the output signal of the fluctuation generator 1. The random number generator 2 continuously generates random numbers at a predetermined interval, and a part of them is extracted by the random number extractor 3. This extracted random number is used as extracted random number data.

  The winning determination table 5 has an area divided for each winning mode corresponding to the entire area of random numbers taken by the random number generator 2. For example, a range of 0 to a certain number is divided into a plurality, one division (area) is excluded, and the other division (area) is set as winning 1 (BB), winning 2 (RB), and so on. To do.

  The determination unit 4 refers to the extracted random number data extracted by the random number extractor 3 with the lottery probability data in the winning determination table 5. That is, the extracted random number data is collated with each winning determination area data segmented for each winning mode in the entire random number area taken by the random number generator 2, and the winning corresponding to the winning mode to which the extracted random number data belongs is determined. To decide. For example, it is determined which category (area) of the winning determination table 5 the extracted random number value belongs to, and if the category is, for example, a category of winning 1 (BB), it is determined as “winning 1 (BB)”. . Similarly, if the extracted random number value belongs to an out-of-range category (region) in the winning determination table 5, it is determined as “out”.

  For example, when the evaluation of the lottery process is out of place, it is set so that the predetermined symbols are not aligned (so-called kicking), and when winning, the predetermined symbols are aligned on the condition that the stop switch is pressed at a predetermined timing. (So-called pull-in). And if predetermined symbols are prepared, medals corresponding to winning symbols are paid out.

  The winning lottery is performed based on the pressing signal of the start switch 30, but in the embodiment of the present invention, the pressing signal is not used as it is, but the signal after the fluctuation signal is given to the pressing signal by the fluctuation generator 1. It is characterized by using. This will be described with reference to FIG.

  FIG. 3A is a timing chart showing the relationship between the pressing signal of the start switch 30 and the random number extraction command output from the fluctuation generator 1. The fluctuation generator 1 outputs a signal delayed by a delay T from the pressing signal of the start switch 30. A random number is extracted by this random number extraction command. If the extraction timing is different, the random number extracted by the random number extractor 3 is also different. Since the delay T is not a constant value and takes a different value every time the start lever 30 is pressed, it is more difficult to predict the extracted random number value. By providing the fluctuation generator 1 in this way, the random number used in the lottery is predicted even if the random number generated by the random number generator 2 is not uniform and has a certain regularity and can be predicted. I can't do that. When the player operates the start switch 30 at a certain timing, the lottery probability cannot be set to a predetermined value or more.

  On the other hand, as shown in FIG. 3B, since the random number is conventionally extracted using the start lever pressing signal as it is, the random number generated by the random number generator 2 is not uniform and has a certain regularity. In some cases, the possibility of predicting random numbers used in the lottery could not be denied.

  According to the winning lottery means of FIG. 2, the start lever pressing signal is used in the meaning that the player himself performs a lottery in the lottery process, but when the random number is acquired by the fluctuation generator 1, the signal is further fluctuated. The timing cannot be taken from outside the gaming machine. Therefore, fraud etc. become difficult.

  Next, the nature of the delay T generated in the fluctuation generator 1 will be described. The delay T takes a different value irregularly, that is, fluctuates. The fluctuation here means that the time from the reception of the pressing signal of the start switch 30 to the generation of a random number extraction command for the random number extractor 3 changes irregularly (difficult to predict) every time. Although it is desirable that the delays T be completely random and have a uniform distribution, in practice, the delays T may be generated at a constant rate. It doesn't have to be regular. Examples of the distribution of the delay T are shown in FIGS. These figures schematically show the delay time and its occurrence frequency.

  In the example of FIGS. 4A and 4A ', the delay time has a uniform distribution in a certain range, and any delay time occurs within the predetermined range. Note that the range need not be limited as indicated by the dotted line. FIG. 4A shows a case where the delay time is 0 or more, and FIG. 4B shows a case where the delay time is distributed around a certain value (hereinafter the same).

  In the examples of FIGS. 4B and 4B, the delay time occurs within a certain range, but the frequency of occurrence decreases linearly as the delay time increases.

  In the example of FIGS. 4C and 4C, there is a distribution peak at a predetermined delay time, and the frequency of occurrence gradually decreases around this. FIG. 5C 'shows a distribution similar to a so-called normal distribution.

  As a specific method for generating the delay T, a known algorithm (Monte Carlo method or the like) can be used, or a physical random number using thermal noise can be used. Although it is desirable that the delays T be completely random and have a uniform distribution, in practice, the delays T may be generated at a predetermined rate.

  Next, the operation of the fluctuation generator 1 according to the embodiment of the present invention will be described with reference to the flowchart of FIG. 5 and the timing chart of FIG. In the present embodiment, the fluctuation generator 1 is realized by software (specifically, a microprocessor that operates according to a program).

  In step S20 of FIG. 5, a CPU (not shown) goes to see the state of a predetermined switch, for example, the start switch 30. The stop switch 50 can also be used as the predetermined switch. Alternatively, instead of the switch, an output signal of an index sensor for detecting the position of the reel (which may be caused by the stop of the reel) is used, or an IN signal (not shown) of a concentration terminal board (not shown) Number of signals) can be used. The IN signal is a signal sent to a hall computer (not shown), and is a signal indicating the number of medals per game inserted when the game is started. It is output after the start lever is pressed, and a pulse signal corresponding to the number of sheets is output.

  In step S21, it is determined whether a predetermined factor has been generated, for example, whether the start switch 30 is pressed and a signal is output. If not (NO), the process proceeds to step S25, waits for the process for a predetermined time, and then repeats the process again. Through the processing of S20, S21, and S25, the CPU monitors a random number latching factor (for example, pressing of the start lever switch 30) every predetermined time (for example, 1.5 ms). This situation is shown in FIGS. The interval t1 of the monitoring timing B is adjusted by step S25.

  When a predetermined factor has occurred in step S21 (YES), the process proceeds to step S22. In FIG. 6, the random number latch factor C becomes active.

  In step S22, a lottery is performed to obtain a random time (irregular time). Here, as a method for obtaining the random time, (1) a method of using a CPU refresh register, (2) a method of configuring a counter by software and using the count value, and (3) hardware for generating random numbers There is a way to prepare (counter etc.).

  The refresh register (1) is a register used for periodically charging (refreshing) a dynamic memory (DRAM) used as a CPU memory. Specifically, the refresh register holds an address for refreshing the DRAM. Since the content of the refresh register changes with time, it can be used for random number generation. Specifically, the value of the refresh register at that time is read at a predetermined timing, and this is applied to a predetermined expression to obtain a random value.

  The method using the counter (2) is basically the same as the method using the hardware counter. Specifically, a predetermined value is stored in a memory or a register, and this is counted up at regular intervals. This value is applied to a predetermined formula to obtain a random value.

  (3) uses a physical random number generator using a counter or thermal noise.

  In addition to the above, a known algorithm (such as Monte Carlo method) may be used.

  In step S23, the generated random time is received, and a wait process is performed for a time corresponding to the random time. Since the random time is a random number, the wait time is irregular.

  In step S24, a random number latch signal is output to the random number extractor 3. The random number extractor 3 takes in the random number of the random number generator 2 based on the latch signal.

  The time from when the random number latch factor C is activated until the random number latch signal is output is the sum of the random time lottery processing time t2 of S22 and the random time weight processing time t3 of S23. As described above, since t3 is irregular, the time from when the predetermined switch A is turned on to the output of the random number latch signal is irregular.

  Next, an outline of the operation of the slot machine having the above configuration will be described with reference to the flowcharts shown in FIGS.

  First, in step S1 shown in FIG. 7, when the start switch 30 is operated, the start switch 30 is turned on. Then, the process proceeds to the next step S2.

  In step S2, lottery processing is performed by the winning lottery means shown in FIG. Then, the process proceeds to the next step S3.

In step S3, the rotation of the rotary reel 40 is started. Then, the process proceeds to the next step S4.
In step S4, when the stop switch 50 is operated, the stop switch 50 is turned on. Then, the process proceeds to the next step S5.
In step S5, rotation stop processing for the rotary reel 40 is performed. Then, the process proceeds to the next step S6.

In step S6, it is determined whether or not the operation of the stop switch 50 corresponding to the three rotary reels 40 has been performed. When it is determined that the operation of the stop switch 50 corresponding to the three rotary reels 40 has been performed, the process proceeds to the next step S7.
In step S7, it is determined whether or not the winning symbols corresponding to the winning flag are aligned on the effective winning line while the winning flag is established, that is, whether or not the winning is confirmed. If it is determined that the winning is confirmed, the process proceeds to the next step S8.

In step S8, medals corresponding to winning symbols are paid out. Then, the process proceeds to next Step S9.
In step S9, when a winning decision is made for a special game of the BB game or RB game, the number of winning decisions for the special game is incremented by one.

The lottery process in step S2 described above will be described using the flow of FIG.
In step S10, fluctuation is added to the start switch pressing signal according to the flowchart of FIG. Then, the process proceeds to the next step S11.
In step S <b> 11, random numbers are extracted by the random number extractor 3 based on a signal to which fluctuation has been added from among the random numbers generated by the random number generator 2. Then, the process proceeds to next Step S12.

In step S12, the extracted random number is stored in the random number extractor 3. Then, the process proceeds to the next step S13.
In step S <b> 13, the determiner 4 compares the extracted random number with the winning determination area data in the winning determination table 5. Then, the process proceeds to the next step S14.

In step S <b> 14, the determiner 4 determines which winning mode of the winning determination table 5 includes the extracted random number, and determines the evaluation of the lottery process. Then, the process proceeds to next Step S15.
In step S15, if the evaluation of the lottery process is out of place, for example, the predetermined symbols are set so as not to be aligned (so-called kicking), and if the win is determined, the stop switch is pressed at a predetermined timing. It is set so that the symbols are aligned (so-called pull-in). Then, the lottery process ends.

  According to the embodiment of the invention, the start lever pressing signal is used in the sense that the player himself / herself performs a lottery. However, when the random number is acquired, the signal is further fluctuated so that the timing can be taken from outside the gaming machine. Absent. Therefore, it is difficult to deliberately aim for winning or cheating.

  In the above description, the fluctuation is generated based on the start switch 30, but the trigger factor is not limited to this. An example is shown below. This factor may be a switch or signal that is operated or activated only once for each game.

(1) Factors that can be easily operated from the outside-Start switch 30
Stop button 50: Since it is harder to predict than the start button, it is preferable in terms of preventing fraud.

(2) Factors that cannot be easily operated from the outside: Index sensor: A sensor for detecting the position of the reel. By relating this output, it is possible to detect that the reel has stopped.
・ IN signal: Signal of centralized terminal board. Sent to the hall computer. An output signal of the number of medals inserted in one game when one game is started. Output after the start lever is pressed. A pulse signal corresponding to the number is output.

  (1) Part or all of the factors of (2) may be adopted, and the latch signal may be output after a lapse of random time after the factors are detected.

  In the embodiment of the present invention, a signal for latching the output of the random number generator 2 is generated by software. Therefore, it is possible to easily change the trigger factor for each model and for each game. This is preferable in terms of prevention of fraud because analysis becomes difficult.

  When implemented by software, it is difficult to use multiple clocks as in the case of hardware, and the clocks are common, so the possibility of analysis / prediction remains, but analysis can be performed by appropriately changing the factors as described above. It can be difficult. According to the software, there is an advantage that it is low-cost, can be easily changed, and is flexible.

  By the way, the factors for starting the random time lottery process are broadly divided into (a) factors related to the start of the game such as a start switch (its signal) and an IN signal, and (b) a stop switch and an index sensor (related to these). There is a factor related to the game stop, such as a forced stop control (a control signal or a reel stop signal) that is performed when the stop switch is not pressed even after a predetermined time has elapsed from the reel rotation (timeout). The output timing of the random number latch signal may be changed depending on which of these is used. This will be described with reference to the timing chart of FIG.

  Reference numerals 100a and 101a in FIG. 9 indicate a case where a random time lottery process is performed due to factors relating to the start of the game. When the start lever is pressed, a random time lottery process 100a is performed, and in response thereto, a random time weight process 101a is performed. When this is completed, a random number latch signal is output. Thereby, S2: lottery process of FIG. 7 is performed. In this example, a lottery is performed at the start of the game, and the control of the rotating reel in the game is performed based on the lottery result.

  Reference numerals 100b and 101b in the figure indicate a case where a random time lottery process is performed due to a factor related to the game stop. When the stop switch is pressed, a random time lottery process 100b is performed, and in response thereto, a random time wait process 101b is performed. When this is completed, a random number latch signal is output. Thereby, S2: lottery process of FIG. 7 is performed. In this example, since the lottery result is obtained after the control of the rotating reel is finished, this is reflected in the next game, and the lottery result is not reflected in the game of the time. This makes analysis more difficult.

  100c, 102, and 101c in the figure perform random time lottery processing due to factors related to game stoppage, but the lottery processing is performed when the start lever is pressed next time. When the stop switch is pressed, a random time lottery process 100c is performed. This result is stored in the register / memory and used in the next game. When the start lever is pressed, the random time is read, and in response to this, the random time wait processing 101b is performed. When this is completed, a random number latch signal is output. Thereby, S2: lottery process of FIG. 7 is performed. Since the random time factor and the lottery factor are separated, the analysis becomes more difficult. Since the lottery itself is based on the start lever, it is considered easy for players to accept.

Embodiment 2 of the Invention
In the fluctuation processing flowchart of FIG. 5, a plurality of factors (switches / signals) may be switched each time. A flowchart of this process is shown in FIG. In FIG. 10, first, S26: a process of setting a plurality of switches / signals, S27: a process of arbitrarily selecting one of the set switches / signals, and S28: other processes after the fluctuation process are performed. A process of arbitrarily selecting a switch / signal is performed. As the factors, the above-mentioned (a) factors related to game start and / or (b) factors related to game stop, specifically, start switch, stop switch, index sensor, IN signal, forced stop of reel due to timeout, etc. are used. .

In step S26, a switch / signal used as a factor is set. Since this setting can be stored as a memory table, it can be easily changed for each model, making analysis more difficult.
In step S27, one of a plurality of factors is selected. The selection may be made randomly, or a plurality of factors may be selected and the logical product or logical sum of them may be used.
In step S28, a factor to be used in the next game is selected. The factors may be switched for each game based on a start switch or the like, or may be switched at predetermined time intervals by a timer.
Since the processing of other steps is as described above, the description thereof is omitted.

  FIG. 11 shows an example of switching factors for each game. In the figure, the horizontal axis is a time axis, and the unit is one game (for example, from when the start lever is pressed until the next start lever is pressed). The factor A related to the game start corresponds to, for example, 100a and 101a in FIG. 9, and the factor B related to the game stop corresponds to, for example, 100b and 101b or 100c, 102, and 101c in FIG. FIG. 11A shows a case where the factor is switched while one game is over and the next game is started. In this example, the factor A related to the game start and the factor B related to the game stop are alternately repeated. FIG. 4B shows a case where the factors are switched after a certain time has elapsed. When selecting the next factor, either simple switching or selection of a factor by lottery may be used. FIG. 3C shows a case where the next factor is selected by lottery when one game ends and the next game starts.

  According to the embodiment of the present invention, the factor that triggers the random time lottery can be switched, so that the analysis can be made more difficult.

Embodiment 3 of the Invention
A lottery was performed in step S22 of FIG. 5 to obtain a random time (irregular time). Here, as a method for obtaining the random time, one or a plurality of values are extracted (including calculation based on a predetermined expression), bit replacement is performed on this value, and the timer wait of S23 is performed based on the bit replacement value. Processing may be performed. As a method of extracting one or a plurality of values, the above-mentioned (1) a method using a CPU refresh register, (2) a method in which a counter is configured by software, and the count value is extracted by the above-described factors, etc. is there. By performing the bit replacement, the random time drawn even when the counter is used becomes sufficiently irregular.

  The refresh register (1) is a register used for periodically charging (refreshing) a dynamic memory (DRAM) used as a CPU memory. Specifically, the refresh register holds an address for refreshing the DRAM. Since the content of the refresh register changes with time, it can be used for random number generation. Specifically, the value of the refresh register at that time is read at a predetermined timing, and this is applied to a predetermined expression to obtain a random value.

  The method using the counter (2) is basically the same as the method using the hardware counter. Specifically, a predetermined value is stored in a memory or a register, and this is counted up at regular intervals. This value is applied to a predetermined formula to obtain a random value.

  How the extracted values are converted in the case of the connection as described above will be described with reference to FIGS. When the counter is used as in (2) above, the random number generator 2 sequentially outputs 0, 1, 2, 3, 4,. However, if the bits are exchanged as shown in FIGS. 12 and 13, the data received by the CPU is 0, 8, 1, 9, 2,. In this way, the numerical value changes greatly even by simple bit replacement (shift of 1 bit). Prediction of the lottery result is difficult just by exchanging bits as described above, which is effective in preventing fraud.

  In the above example of bit replacement, the entire bit is shifted by 1 bit (of course, it may be shifted by 2 bits or more). Another bit replacement technique is bit replacement. Hereinafter, the replacement of bits will be described.

  Bit exchange is to exchange one or more sets of bits. The replacement of some of the plurality of bits constituting the random number will be specifically described based on the simulation result. The following example is for 8 bits. In the following description, the “change period” is the data change period received by the CPU when bits are exchanged, and the “change amplitude” is the data change width (change change). If the width is not constant, its maximum value). Specifically, please refer to FIG.

(1) Replacing one set of bits The simulation results are shown in FIG. By appropriately selecting the combination of bits, the change amplitude can be set to 2 to 128, and the change period can be set to 2 to 32. Although not shown, the graph when one set of bits is exchanged is considered to be not very effective because it is linear to the right even when the amplitude is large. As will be described later, it is preferable that the change period is short and the change amplitude is large. From this point of view, when evaluating one set of bit replacement, it is optimal to replace bit0 with bit7. It is better to swap the upper and lower bits. However, the bit replacement in FIG. 15 includes bit replacement that is not preferable (such as replacement of bit0 and bit1).

(2) Replacing two or more sets of bits The simulation result is shown in FIG. In this case, the change amplitude can be 32 or 128, and the change period can be 2. The graph when two or more sets of bits are exchanged has a large amplitude, and since the graph is quite different from the linear shape rising to the right before the bit exchange, an effect can be expected. From the viewpoint that it is preferable that the change period is short and the change amplitude is large, all the bit exchanges shown in FIG. 16 are preferable. Therefore, it is preferable to exchange at least two sets of bits.

Embodiment 4 of the Invention
With respect to the counter used for the random time lottery in S22 of FIG. 5, the counter value is not synchronized with the passage of time by stopping or restarting the update at a predetermined opportunity. Therefore, even if the start switch is pressed at a certain timing, a random number that is not the intended value can be acquired, thereby preventing fraud. The effect is further enhanced by providing such random number update stop / restart events at a plurality of locations.

For example, there are the following triggers for selecting an irregular time (hereinafter expressed as stopping or restarting the update of random numbers).
(1) The random number update is stopped based on a signal from an arbitrary stop switch (stop button) 50, and the update is restarted based on a reel stop signal from the reel drive unit 70 or the reel position detection circuit 71. This utilizes the sliding of the rotating reel (rotating drum) 40 until it stops. The degree of this slip changes irregularly every time the stop button is pressed or the lottery result.
(2) The random number update is stopped based on a medal insertion detection signal from a medal selector (not shown), and the update is restarted based on a signal from the start switch 30.
(3) The random number update is stopped based on the signal from the start switch 30, and the update is restarted based on the reel index detection signal from the reel position detection circuit. Depending on the reel stop state, the time until the first index detection (or up to a specific number of times) varies irregularly every time. Specifically, a certain reel is determined in advance, and the time when the index is first detected (or a specific number of times) after the rotation of the reel is started is used. Alternatively, a plurality of index detection signals of three or four reels are selected and combined (for example, a logical sum is obtained), and the first (or a specific number of times) index detection signal is used. Good.
(4) The random number update is stopped based on a signal from an arbitrary stop switch (for example, the first stop switch) 50, and the update is restarted based on a signal from another arbitrary stop switch (second stop switch) 50.
(5) The random number update is stopped based on the subcommand transmission request, and the update is restarted when the subcommand transmission is started. The time from when a subcommand transmission request is received until when the subcommand is actually transmitted varies depending on the processing status of the CPU. For example, it varies between 0 and 36 ms.

  The examples (1) to (5) will be described in detail.

  The update is stopped based on a signal from an arbitrary one of the stop switches (stop buttons) 50, and the update is restarted based on a reel stop signal from a reel drive unit or a reel position detection circuit. This utilizes the sliding of the rotating reel (rotating drum) 40 until it stops. The degree of slipping varies irregularly each time.

  FIG. 17 is a block diagram showing an electrical schematic structure of the slot machine 10. In this figure, the display about the power supply system is omitted. The slot machine 10 includes a main substrate 1 (first processing unit) and a sub substrate 2 (second processing unit) that operates in response to a command from the main substrate 1 (first processing unit). At least the main substrate 1 is accommodated inside the case so that it cannot be contacted from the outside, and a sealing process is performed so that traces remain when the substrates are removed.

  The main board 1 is for performing an internal lottery in response to a player's operation, and processing such as reel rotation / stop and medal payout. The main board 1 includes a CPU that performs a control operation according to a preset program, a ROM that is a storage unit that stores the program, and a RAM that temporarily stores processing results and the like. The main board 1 includes an update stop signal generator 1a that generates a signal for instructing a random number generator 20 (described later) to stop random number update under a predetermined condition. This is realized by software, for example, and in this case, this processing is executed by the CPU of the main board 1. A program for performing this processing is written in the ROM of the main board 1 in advance.

  The sub-board 2 is for receiving a command signal from the main board 1 and notifying the result of the internal lottery and performing various effects. The sub-board 2 includes a CPU that performs a control operation according to a preset program corresponding to the command signal, a ROM that is a storage unit that stores the program, and a RAM that temporarily stores processing results and the like.

  The sub-board 2 receives a command from the main board 1 and performs processing such as rendering according to the command. The flow of commands is only one from the main board 1 to the sub board 2, and conversely, no command or the like is issued from the sub board 2 to the main board 1.

  To count the number of medals paid out from the random number generator 20, start switch 30, stop switch 50, reel drive unit 70, reel position detection circuit 71, hopper drive unit 80, hopper 81 and hopper 81 on the main board 1. Are connected to the medal detection unit 82. A peripheral board (local board) such as a control board 200 of the liquid crystal display device 62, a speaker 201, and an LED board 202 is connected to the sub board 2. Hereinafter, these peripheral substrates / devices except for the start switch 30 and the stop switch 50 will be described.

  The random number generation unit 20 has a random number generation function for generating a pseudo random number by updating the numerical values in a certain range at high speed, and a sampling function for extracting an arbitrary random number from the generated random numbers in response to the player's operation. It is to be prepared. As a specific example, it is composed of a counter and a latch.

  The reel driving unit 70 is a circuit that drives a stepping motor (not shown) that rotationally drives the three reels 40. Each stepping motor is subjected to 1-2 phase excitation by the reel drive circuit 70 and rotates once when a drive signal having a predetermined number of pulses is supplied.

  The reel position detection circuit 71 is provided in the vicinity of the reel 40, receives an output pulse signal from a photo interrupter (not shown) for detecting the rotation position of the reel 40, detects the rotation position of each of the three reels 40, and detects it. A signal is output. A photo interrupter (not shown) detects a shielding plate provided on each reel 40 and generates a reset pulse every time each reel 40 rotates once. This reset pulse is given to the CPU of the main board 1 via the reel position detection circuit 71. In the RAM of the main board 1, a count value corresponding to the rotation position within one rotation range is stored for each reel 40, and when the CPU receives the reset pulse, the count value formed in the RAM is stored. Clear to “0”. By this clearing process, the deviation generated between the movement display of each symbol and the rotation of each stepping motor is eliminated every rotation.

  The hopper driving unit 80 is a circuit that drives a motor of a hopper 81 that stores medals and pays out the number of medals corresponding to the designated winning.

  The medal detection unit 82 is for counting the number of medals paid out from the hopper 81. The CPU of the main board 1 stops driving by the hopper driving unit 80 when the actually paid out medal count value received from the medal detection unit 82 reaches the predetermined payout number data corresponding to the winning. Finish paying out. A predetermined number of medals are paid out to the player by the hopper driving circuit 80 and the medal detection unit 82 based on a winning obtained as a result of the game.

The liquid crystal control board 200 is a circuit for driving the liquid crystal display unit 62.
The speaker 201 is for generating sound such as voice and sound effects.
The LED substrate 202 is a circuit for driving a display lamp and a back lamp (not shown).

  The liquid crystal display device 62 controlled by the liquid crystal control substrate 200 and the LED substrate 202 including the speaker 201 and the display lamp constitute an effect display device. This effect display device is for notifying a player of a prize or the like, or for teaching a user a specific small role during a certain game with some action during a so-called assist time (AT).

  FIG. 18 shows a flowchart of processing according to the first embodiment.

S1: When a medal is inserted or the bet switch 16 is pressed, a game is possible.

S2: When the start lever 30 is pushed in this state, the game is started. That is, the rotary reel 40 rotates and the process of S3 is performed.

S3: A hardware random number is latched. This corresponds to S11 in FIG. This is a random value in the game.

S4: A symbol lottery process is performed based on the random number. This is a known process and will not be described in detail.

S5: It is determined whether or not the stop button 50 is depressed. When pressed down (YES), the process of S6 is performed. Since there are three stop buttons 50, there are several patterns depending on which button the signal is used from. That is, (1) a specific button among the three buttons is determined in advance and the signal of the specific button is used, and (2) two buttons are determined in advance from the three buttons, and the logical sum of these signals is determined. (3) Use logical OR of all three signals. The first embodiment includes cases (1) to (3) or cases equivalent to these.

S6: When the stop button 50 is depressed, the hardware random number update is stopped.

S7: When the stop button 50 is depressed, the stop position determination process of the rotary reel (rotating drum) 40 is performed. This is a known process and will not be described in detail.

S8: It is determined whether or not the rotating reel (rotating drum) 40 has stopped. When stopped (YES), the process of S9 is performed. Since there are three rotary reels 40, there are several patterns for which rotary reel 40 stop signal is used. Since it is the same as that of the stop switch 50, detailed description is abbreviate | omitted.

S9: Restart the hardware random number update. The time from S6 to S9 becomes irregular time.

S10: It is determined whether or not all the rotation reels (rotating drums) 40 are stopped. When stopped (YES), the process of S10 is performed.

S11: A winning determination process is performed. This is a known process and will not be described in detail.

S12: A payout process is performed. This is a known process and will not be described in detail.
By the way, whether or not the corresponding winning symbol can be aligned on the effective winning line while any one of the winning flags is established depends on the timing of the stop switch 50 when the rotation speed of the rotary reel 40 is constant. is there. Specifically, since the rotary reel 40 is set to stop within 190 ms after operating the stop switch 50, it can be stopped as it is after operating the stop switch 50, or can be stopped within 190 ms. When the corresponding winning symbol 61 is included in the retractable symbols 61 on the circumference of the rotating reel 40, for example, four consecutive retractable symbols 61, the time until stopping is delayed. The rotary reel 40 draws the winning symbol on the effective winning line and stops. On the other hand, when the corresponding winning symbol 61 is not included in the four retractable symbols 61, the winning symbol cannot be drawn on the effective winning line and stopped.

  As described above, the time from S6: stop of updating the hardware random number to S9: restart of update of the hardware random number corresponds to the stop time of the rotating reel (rotor) 40 to be processed in S8. To do. The stop time of one rotary reel 40 is about 7.5 ms to 190 ms, but this is different each time depending on the timing of pressing the stop button, the result of the internal lottery, and the like. In other words, since the stop time of the rotary reel 40 always fluctuates, this can be used as a fluctuation signal. The width of fluctuation by one rotating reel 40 is about 183 ms. In terms of the entire three rotating reels 40, the stop time is about 22.5 ms to 570 ms, and the fluctuation width is about 548 ms. Since the fluctuation width of the rotating reel 40 is larger than the update cycle of the hardware random number, the update cycle can be irregularly changed.

  In order to facilitate understanding of the first embodiment, a specific configuration of the rotating reel (rotating drum) will be described.

  As shown in FIG. 19, each of the reels 40 a to 40 c is configured as a rotary reel unit, and is attached to the frame 151 via a bracket 152. Each of the reels 40a to 40c has a reel band 154 attached to the outer periphery of a reel drum 153. The symbol row (design 61) is drawn on the outer peripheral surface of the reel band 154. Each bracket 152 is provided with a stepping motor 155, and the reels 40a to 40c are driven by the motor 155 to rotate.

  The structure of each reel 40a-40c is shown in FIG. A lamp case 156 is provided inside the reel drum 153 behind the reel band 154, and back lamps 157a, 157b, and 157c are attached to the three rooms of the lamp case 156, respectively. These back lamps 157 a to 157 c are mounted on a substrate 158 as shown in FIG. 20B, and this substrate 158 is attached to the back of the lamp case 156. A photo interrupter 159 is attached to the bracket 152. A photointerrupter is a case in which a light emitting element (such as a light emitting diode) and a light receiving element (such as a phototransistor or a photodiode) are arranged to face each other, and a detection groove is provided between them. The passage is detected without contact. The photo interrupter 159 detects that the shielding plate 160 provided on the reel drum 153 passes through the photo interrupter 159 as the reel drum 153 rotates. The signal from the photo interrupter 159 is input to the reel position detection circuit 71 in FIG.

  The back lamps 157a to 157c are individually controlled to be turned on by a lamp driving circuit (not shown). By turning on each of the back lamps 157a to 157c, among the symbols drawn on the reel band 154, three symbols located at the front of each of the back lamps 157 are individually illuminated from behind, and are respectively displayed on the symbol display window 13. Three symbols are displayed.

  By operating the start lever 30, the reels 40a to 40c rotate all at once. The three stop buttons 50-50 are arrange | positioned corresponding to each reel 40a-40c. When the rotational speed of each reel 40a-40c reaches a certain speed, the operation of each stop button 50-50 is validated, and each stop button 50-50 is activated according to the player's push button operation. Stop rotating.

  The reel position detection circuit 71 receives the output pulse signal from the photo interrupter 159 and detects the rotational position of each reel 40. The photo interrupter 159 detects the shielding plate 60 and generates a reset pulse every time each reel 40 makes one rotation. This reset pulse is applied to the main board 1 via the reel position detection circuit 71. In the RAM of the main board 1, a count value corresponding to the rotation position within one rotation range is stored for each reel 40. When the CPU of the main board 1 receives a reset pulse, it is formed in the RAM. The counted value is cleared to “0”. By this clearing process, the deviation generated between the movement display of each symbol and the rotation of each stepping motor 155 is eliminated every rotation. When the stop switch 50 is pressed, a signal for stopping the corresponding reel 40 is sent to the main board 1.

  In the second embodiment, the random number update is stopped based on a medal insertion detection signal from a medal selector (not shown), and the update is restarted based on a signal from the start switch 30. The flowchart of Example 2 is shown in FIG. S20 and S21 are steps for determining the insertion of the first medal. According to the second embodiment, the update of the random number is stopped between the insertion of the first medal and the pressing of the start switch 30. Except for this point, the operation is the same as that of a conventional gaming machine, and thus detailed description is omitted.

  In the third embodiment, the random number update is stopped based on the signal from the start switch 30, and the update is restarted based on the reel index detection signal from the reel position detection circuit 71. When the reel rotation is started, the shielding plate 160 provided on the reel drum 153 blocks the light from the photo interrupter 159 until it rotates 360 degrees at the latest. This output is input to the main board 1 as an index detection signal. In the third embodiment, the update of random numbers is stopped between the start and the first index detection. Since the stop state of the reels after the game varies every time, the time until the first index detection changes irregularly every time. The flowchart of Example 3 is shown in FIG. S30 is a step for detecting the first index of the drum. Except for this point, the operation is the same as that of the gaming machine of the first embodiment, and the detailed description thereof is omitted.

  In the fourth embodiment, random number updating is stopped based on a signal from an arbitrary stop switch (for example, a first stop switch) 50, and updating is restarted based on a signal from another arbitrary stop switch (second stop switch) 50. That's it. The flowchart of Example 4 is shown in FIG. This figure shows only the processing related to the stop button. While the stop button press and the stop position determination process of the rotating reel (rotating cylinder) are repeated three times, the update of the random number is stopped by the first stop button, and the update of the random number is restarted by the second stop button. Restart may be the third stop button. The random number update may be stopped by the second stop button, and the random number update may be restarted by the third stop button. Except for the above points, the operation is the same as that of a conventional gaming machine, and a detailed description thereof will be omitted.

  In the fifth embodiment, the random number update is stopped based on the subcommand transmission request in the main board 1, and the update is restarted in response to the start of the subcommand transmission. Examples 1 to 4 are all related to the player's operation, but Example 5 is triggered only by the internal processing of the apparatus. The present invention includes those triggered by internal processing of the apparatus. The time from when the subcommand transmission request is received until the subcommand is actually transmitted varies depending on the processing status of the CPU. For example, it varies between 0 and 36 ms. This time can be used as fluctuation. FIG. 24 shows a timing chart according to the fifth embodiment. When a subcommand transmission request is generated at t10 and the transmission start of the subcommand is t11, the time from t10 to t11: delay T fluctuates, and the repetition period of the timing counter at this time is delayed to the standard repetition period T Will be added.

Embodiment 5 of the Invention
In S22 of FIG. 5, the output of the counter may be used as a seed of random numbers, and a random number may be generated using a known algorithm (for example, linear congruential method, MT method, average sampling method, exponential random number sequence, etc.).

  The software timer counter continues to count up (count down) at a predetermined timing. A random number is generated using a known algorithm with the output of the counter timer extracted as a seed of random numbers, and the random numbers are associated with random times. A lottery is performed based on this output. Since the seeds of random numbers take various values, the generated random number sequences are preferable because they are not the same.

  When generating a random number in the sub-board 2, it is preferable to latch the output of the timer counter 2a at the reception timing of the command sent from the main board 1. Since a random time delay occurs in the reception timing of the command (see the description of (5) of the fourth embodiment of the invention), the possibility that the seeds of random numbers take the same value or a regular value is reduced. .

  The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.

  In the present specification, the term “unit / means” does not necessarily mean a physical means, but includes cases where the functions of the respective units / means are realized by software. Further, the function of one part / means may be realized by two or more physical means, or the function of two or more parts / means may be realized by one physical means.
