Description

  The present invention relates to a slot machine that executes a lottery for determining an internal winning combination from a plurality of combinations including a small combination and a bonus combination in accordance with the start of a game and establishes an internal winning combination flag.

In the current slot machine, the internal winning flag for the small role is erased at the end of the game regardless of whether or not a prize has been won, and the internal winning flag for the bonus role is configured to carry over any number of games until winning. ing. Such a configuration is based on the idea that there is no need to carry over a small combination because the loss of the small combination is small compared to the bonus combination. However, in practice, if a small part is overwritten repeatedly, a loss of several tens to several hundreds per day (hundreds to several thousand yen when converted into monetary amounts) will occur, and the loss is not necessarily small. . Under such circumstances, a proposal has been made to compensate for missing small roles (see, for example, Patent Document 1).
JP 2004-8391 A

  However, in the configuration that compensates for missing the small role, there is a concern that the player's tension will be weakened and the interest will be reduced.

  The present invention has been made in view of the above-described circumstances, and its purpose is to moderately suppress a loss due to a small role being overlooked, and to create a situation in which an overthrow that should originally be a loss works favorably for a player. Thus, an object is to provide a slot machine that can enhance the interest of games.

According to the first aspect of the present invention, there is provided a symbol variation display means for variably displaying a plurality of types of symbols in a plurality of symbol display areas, and a game start operated by a player in order to start the game with a game medium inserted. Operating means, internal lottery means for establishing an internal winning combination flag by executing a lottery for determining an internal winning combination from a plurality of combinations including a small combination and a bonus combination in accordance with the start of the game; The stop operation means operated by the player to stop the display of the fluctuation of the symbol by the symbol fluctuation display means, and the symbol corresponding to the internal winning combination when the stop operation means is operated within a predetermined pull-in range. If the bonus is not won in the game in which the bonus control flag is established by the display control means that is drawn in and stopped in the symbol display area, and the internal lottery means If the bonus combination is not won in a game in which the bonus combination flag carry-over means to carry over the bonus combination flag until the prize is won and the internal lottery means establishes the small role flag, the small combination flag is set in advance. Carry-over flag carry-over means for erasing the small-combination flag carried over when the predetermined period has passed and a number corresponding to the type of the small-combination according to the winning of the small-combination comprising of a game medium providing means for providing to a player a game medium, and a privilege providing means for providing the advantageous benefits for the player in a state in which the small Win flag carryover means is carryover a small winning combination flag, the small In a game in which a combination flag is established and a game in which the small combination flag is carried over, the bonus granting hand is configured to notify the player that the small combination can be won. Is the number of game media provided by the game medium providing means when the small combination wins in a state where the small combination flag carry-over means carries over the small-combination flag from the number corresponding to the type of the small combination Is also characterized in that it is increased with a predetermined probability .

In the invention described in claim 2 , the internal lottery means can simultaneously determine a small combination and a bonus combination as an internal winning combination in one game, and can simultaneously establish a small combination flag and a bonus combination flag. The bonus granting means determines the number of game media to be given by the game medium granting means when the small bonus is won in a state where the small bonus flag carryover means carries over the small bonus flag. Is characterized in that it increases with a different probability depending on whether or not the bonus combination flag is carried over.

  According to the first aspect of the present invention, when a small role is missed without winning a prize in the game in which the internal lottery means establishes the small role flag, the small role flag is set for a predetermined period of time. It is configured to delete only the carry-over and the carry-over small role flag when the predetermined period elapses. It is possible to moderately reduce a loss due to missing a small role without losing a sense of tension to the player during a period in which the small role flag is carried over while winning a prize. In addition, when the predetermined condition is satisfied in the state where the small role flag carry-over means carry over the small role flag, it is configured to give a privilege that is advantageous to the player. By creating a working situation, you can enhance the fun of the game.

In addition , when the small role is won in the state where the small role flag carry-over means carries over the small role flag, the number of game media given by the game medium grant means is set at a predetermined probability than the number corresponding to the type of the small role. Since it is configured to increase, the player is motivated to intentionally miss the small role and carry the small role flag, so that a new game can be generated and the interest can be enhanced.

According to the invention described in claim 2 , the internal lottery means can simultaneously determine the small combination and bonus combination as the internal winning combination in one game and simultaneously establish the small combination flag and bonus combination flag. In this case, if the small role wins in the state where the small role flag carry-over means carries over the small role flag, the bonus combination flag carry-over means carries the bonus combination flag over the number of game media granted by the game medium grant means Because it is configured to increase with different probabilities depending on whether or not, by observing the number of game media given when the small role wins, you can indirectly estimate the degree of expectation of simultaneous winning, It can enhance interest.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 schematically shows the front appearance of the slot machine. A display window 2 is provided in front of the slot machine 1, and the player can visually recognize the symbols on the reel 3 (the symbol variation display means in the present invention) provided therein through the display window 2. In this case, as shown in FIG. 3, the symbols are drawn on the circumferential surfaces of the left reel 3a, the middle reel 3b, and the right reel 3c, and when the reels 3a to 3c are stopped, the upper stage of the display window 2 is displayed. The symbols are displayed corresponding to the middle and lower stages. The display window 2 is provided with a total of five winning lines (three horizontal lines corresponding to the upper, middle, and lower stages and two diagonally arranged) (shown by broken lines in FIG. 1). The active line display unit 4 for displaying the activated pay line is provided on the side of the, and a corresponding win is generated when the winning symbols are aligned on any of the pay lines. .

  Above the display window 2, a liquid crystal display device 5, a data display button 6 and a speaker 7 are provided for displaying various information such as the progress of payout of medals in bonus. Below the display window 2 are provided a MAXBET button 8 for placing a credit medal bet, a settlement button 9 for settlement of a credit medal, and a medal insertion slot 10 for placing a medal. (Game start operation means in the present invention), left stop button 12 (stop operation means in the present invention), middle stop button 13 (stop operation means in the present invention), and right stop button 14 (stop operation in the present invention) Means). On the right side of the display window 2, a payout number display unit 15 that displays the number of medals paid out and a credit number display unit 16 that displays the number of credits of medals are provided. Further, a tray 17 is provided at the lowermost front part of the slot machine 1, and a decorative lamp 18 is provided at the uppermost front part of the slot machine 1.

  When the slot machine 1 operates a series of game start operations, that is, when the player operates the start lever 11 with a medal inserted into the medal slot 10 or with a credit medal placed through the MAXBET button 8, an internal lottery is performed. Each reel 3a-3c is started (rotation operation is started).

  And after starting each reel 3a-3c, the slot machine 1 stops each reel 3a-3c according to operation of each stop button 12-14, and complete | finishes one game. If the result of the internal lottery is winning, the internal winning flag (big bonus hand flag, regular bonus hand flag, small part flag, replay flag) corresponding to the internal winning part won by the internal lottery is turned on (established) Based on the internal winning flag, stop control including so-called slip control (retraction control) (control to stop each reel 3a to 3c with a winning symbol or a lost symbol according to the type of the internal winning flag) The number of medals corresponding to the winning symbol is discharged to the tray 17. The pull-in control is a control capable of drawing and stopping up to four symbols on the winning line from when the operation of the stop buttons 12 to 14 is detected.

  As the winning symbols, as shown in FIG. 4, a big bonus symbol, a regular bonus symbol, a small role symbol, and a replay symbol are set. In this case, two types of big bonus symbols, one big bonus symbol and two big bonus symbols, are set, and one type is set as the regular bonus symbol. In addition, as a small role symbol, for example, five medals symbols (Sun symbol) in which the number of medals to be paid out is changed to any one of 1, 5 and 15 and 10 medals to be paid out are fixed at 10 There are three types of symbols: an orange symbol, and a double symbol (cherry only symbol) in which the number of medals paid out is fixed at two.

  In the slot machine 1, a specific employee operates the set value operation unit with the front door opened, and thus the winning probabilities for the above-mentioned big bonus and regular bonus are in a plurality of stages (for example, 6 stages of 1 to 6). The larger the numerical value (setting value), the larger the winning probability of the big bonus and the regular bonus. The winning probabilities for small bonuses and replays other than the big bonus and regular bonus are not different depending on the set values, and the winning probabilities common to all the set values are set. Note that the small role and the replay may be set in a plurality of stages, like the big bonus and the regular bonus.

  FIG. 5 shows a winning random number table used in the normal state (non-bonus state) when the set value is set to “6”. In the internal lottery performed when the game is started, one random number is extracted from random numbers generated in the range of 0 to 65535 in decimal numbers, and the extracted random number is collated with the above-described winning random number table to determine the internal winning combination. To decide. Therefore, the winning probability of each combination is a value obtained by dividing the number of winning random numbers by the total number of random numbers (65536). The winning random number table is set separately for each set value (1 to 6) and for each gaming state (normal state, big bonus state, regular bonus state).

  Now, of the above three types of small combinations, the five combinations are small combinations having the possibility of winning simultaneously with the big bonus. That is, as apparent from the winning random number table shown in FIG. 5, when the set value is “6”, “8980” to “9779” are set as the winning random numbers for the five-piece combination, and “ 8980 ”to“ 9079 ”are set, and“ 9089 ”to“ 9129 ”and“ 1982 ”to“ 19851 ”are set as the winning random numbers for Big Bonus 2. In the case of Big Bonus 2, five winning combinations and 50% chance are won at the same time, and 50% chance is not won at the same time (single winning). That is, the ratio of winning the big bonus at the same time when the winning combination is 5 ((100 + 50) / 800) = about 1 / 5.3.

  Further, the five winning combination is a small combination that can carry over the internal winning flag when the internal winning flag is not won in the game (when it is missed). The period during which the five-piece combination flag, which is an internal winning flag for five-piece combination, can be carried over is two games. In other words, the 5-player combination has a chance to win over 3 games including the game in which the 5-player combination flag is established. In a game carrying over the five-piece combination flag (two games after the game in which the five-piece combination flag is established), the payout number of the five-piece combination in the game is determined by lottery. When a 5 winning combination is won in a game in which a 5 winning combination flag is established, “5” medals are paid out. Note that in a game carrying over the five-piece combination flag, the five-piece combination flag is excluded from the internal lottery, so that two or more five-piece combination flags will not be established. FIG. 6 shows a payout number lottery table in the carry-over state of the five-piece combination flag. In the payout number lottery performed in a game carrying over the five-piece combination flag, one random number is extracted from random numbers generated in the range of 0 to 127 in decimal numbers, and the extracted random number is used as the payout number lottery table described above. The number of payouts is determined by collation.

  As described above, the five-piece combination is a small combination having the possibility of winning simultaneously with the big bonus, and the payout number lottery table is set differently depending on whether or not the big bonus is won simultaneously. FIG. 6A shows a payout number lottery table to be collated when winning simultaneously with the big bonus, and FIG. 6B shows a payout number lottery table to be collated when not winning simultaneously with the big bonus. Show. In this case, the expected value of the average payout number of medals when winning simultaneously with the big bonus is “9.30”, and the expected value of the average payout number of medals when not winning simultaneously with the big bonus is “9.30”. 5.77 ”, the former being higher than the latter, both being“ 5 ”or more. In other words, when a 5 winning combination is won in a game where the 5 winning combination flag is established, 5 medals are always paid out, whereas in a game where the 5 winning combination flag is established, the 5 winning combination is not won. In the case of a game in which the five-piece combination flag is carried over and the five-piece combination wins, the expected value of the payout number exceeds “5”. The winning random numbers shown in FIGS. 5 and 6 are examples, and the winning probability of each combination including replay can be arbitrarily set. The big bonus 1 and the big bonus 2 are ended when the number of medals to be paid out exceeds 465, which is predetermined as an upper limit, and the regular bonus is 250, where the number of medals to be paid out is predetermined as an upper limit. It ends when the number of sheets is exceeded.

  FIG. 2 is a functional block diagram showing the electrical configuration of the slot machine 1 described above. The control unit 19 (internal lottery means, display control means, bonus combination flag carryover means, small role flag carryover means, game medium grant means, privilege grant means in the present invention) includes a CPU, ROM, RAM, I / O, and the like. Each operation signal is input from the start lever 11, left stop button 12, middle stop button 13, right stop button 14, data display button 6, MAXBET button 8, and checkout button 9. .

  Further, the control unit 19 inputs an inserted medal detection signal from the inserted medal detection unit 20 that determines the authenticity and quantity of medals inserted into the medal insertion slot 10, and inputs each setting signal from the set value operation unit 21. . Further, the control unit 19 detects the passage of a reel driving unit 23 that drives the reel motors 22a to 22c corresponding to the reels 3a to 3c, and a reference position piece provided on each reel 3a to 3c. A reference position detection unit 25 that detects a reference position based on detection signals from the sensors 24a to 24c, an audio output unit 26 that drives the speaker 7 described above, a medal payout unit 27 that releases a medal to the tray 17, and the liquid crystal display described above The apparatus 5, the effective line display unit 4, the payout number display unit 15, the credit number display unit 16 and the decoration lamp 18 are connected.

  In this case, the control part 19 is based on each input signal and the control program memorize | stored in ROM, the reel drive part 23, the audio | voice output part 26, the medal payout part 27, the liquid crystal display device 5, the effective line display part 4, Controls the operations of the payout number display unit 15, the credit number display unit 16, and the decoration lamp 18, and outputs an out signal (one pulse output for each medal insertion or one credit medal bet) and a safe signal (one medal payout). 1 pulse output for each or every credit medal payout), game signal (1 pulse output for each game start), big bonus signal (level signal output during the big bonus period), and regular bonus signal (during the regular bonus period) Level signal output) is generated and output from a signal output terminal (not shown) to the outside. Various signals output from the signal output terminal are input to a management device installed in the game arcade, and are used to manage the operating status of each slot machine 1.

  Next, the operation of the above configuration will be described with reference to FIGS. The control unit 19 periodically performs an internal lottery process and a winning determination process. Hereinafter, the internal lottery process and the winning determination process will be sequentially described.

(1) Internal lottery process When the internal lottery process is started, the control unit 19 determines whether or not a medal has been inserted into the medal slot 10 (S1), and determines that a medal has been inserted into the medal slot 10 ( S1: YES), it is determined whether or not the start lever 11 has been operated (S2), and if it is determined that the start lever 11 has been operated (S2: YES), an internal winning combination occurring in the range of 0 to 65535 is determined. Any one of the random numbers is extracted (S3). Then, the control unit 19 checks the extracted random number against the winning random number table corresponding to the current state (S4), turns on the winning internal winning combination flag (S5), and shifts to the payout number lottery process (S6). ).

  When the control unit 19 shifts to the payout number lottery process, the control unit 19 determines whether or not the five-game handover flag is turned on at that time, that is, whether or not the game is a game that carries the five-game hand flag. If it is determined that the five-carrying carryover flag is not turned on at that time (S11: NO), the payout number lottery process is terminated without performing the subsequent processes, and the process returns. The 5-hand carryover flag is a flag that is turned on when a 5-game winning combination is not won in the game in which the 5-game winning flag is established (when it is missed).

  On the other hand, if the control unit 19 determines that the five-carrying carryover flag is turned on at that time (S11: YES), a random number for determining the number of medals to be paid out in the range of 0 to 127. Any one of them is extracted (S12), and it is determined whether or not the big bonus combination flag is turned on at that time, that is, whether or not the big bonus is simultaneously won (S13). Next, when it is determined that the big bonus combination flag is turned on at that time (S13: YES), the control unit 19 compares the extracted random number with the payout number lottery table when the big bonus is simultaneously won, The determined medal payout number is stored in the RAM (S16), the medal payout number is displayed on the liquid crystal display unit 5 (S17), the payout number lottery process is terminated, and the process returns. On the other hand, if the control unit 19 determines that the big bonus combination flag is not turned on at that time (S13: NO), the extracted random number is checked against the payout number lottery table when the big bonus is not won simultaneously, The determined medal payout number is stored in the RAM (S16), the medal payout number is displayed on the liquid crystal display unit 5 (S17), the payout number lottery process is terminated, and the process returns.

As shown in FIG. 10 (a), the control unit 19 displays a five-player symbol in a game in which a five-player combination is won internally (a game in which a 5-player combination flag is established) and a game that carries the 5-player combination flag. The information is displayed on the liquid crystal display device 5 and the player is notified that it is possible to win five winning combinations. At this time, the control unit 19 displays in the sun symbol that the number of medals to be paid out is 5 in the game in which the 5-piece combination flag is established, and the number of medals to be paid out in the game carrying the 5-piece combination flag. The payout number determined by the lottery is displayed in the sun symbol. In addition, the number of games that can be carried over by five players is displayed in the lower right corner of the display area when viewed from the player, and the number of games that can be carried over is notified to the player. In FIG. 10A, it is displayed that the number of payouts is “5” and the number of games that can be carried over is “2” in the game in which the 5-player combination flag is established. Further, the control unit 19 displays the characters “Congratulation !!” as shown in FIG. 10 (b) when the five-piece combination and the big bonus combination are won simultaneously and the five-piece combination wins. The player is informed that the five-piece combination and the big bonus combination are won simultaneously and that the five-piece combination has won.

(2) Winning determination processing When starting the winning determination processing, the control unit 19 determines whether or not the three reels 3a to 3c are stopped (S21), and determines that the three reels 3a to 3c are stopped ( S21: YES), it is determined whether or not the bonus has been won (S22). If the control unit 19 determines that the bonus has been won (S22: YES), the bonus game flag is turned on (S23), the bonus combination flag is turned off (S24), and the five-piece carryover flag is turned off ( S25), the small combination flag is turned off (S26), the winning determination process is terminated, and the process returns.

  In contrast, when the control unit 19 determines that the bonus has not been won (S22: NO), the control unit 19 determines whether or not the small role has been won (S27) and determines that the small role has been won (S27: YES), a predetermined number of medals are paid out according to the winning small combination (S28), and it is determined whether or not the five-piece carryover flag is turned on (S29).

  When the control unit 19 determines that the five-piece winning combination flag is turned on (S29: YES), the control unit 19 determines whether or not the winning small combination is a five-piece winning combination (S30). If it is determined that the combination is a double combination (S30: YES), the 5 double combination carryover flag is turned off (S25), the small combination flag is turned off (S26), the winning determination process is terminated, and the process returns. If the control unit 19 determines that the winning small combination is not a five-piece combination (S30: NO), the number of carryover games is incremented (S31), and it is determined whether or not the number of carryover games has reached “2”. If it is determined that the number of carryover games has not reached “2” (S32: NO), the small role flag is turned off (S26), the winning determination process is terminated, and the process returns. On the other hand, if the control unit 19 determines that the number of carryover games has reached “2” (S32: YES), it turns off the five-piece carryover flag (S25), turns off the small combination flag (S26), and wins a prize. The determination process ends and the process returns.

  As described above, according to the present embodiment, in the slot machine 1, if a five-piece combination is missed without winning a five-piece combination in a game in which the five-piece combination flag is established, the five-piece combination flag is displayed. Only the two games after the established game carry over the 5-player flag, and when the 2 games that carry the 5-player flag are digested, the 5-player flag is erased. Even so, the player will aim to win five roles in the game until the two games are digested, and moderately control the loss due to losing the five-player role without losing tension to the player. Can do. In addition, when the 5 winning combination is won with the 5 winning combination flag, the expected value of the payout number is set to exceed 5 so that the player intentionally drops the 5 winning combination. It becomes motivation to carry over the flag, can generate a new game, and can enhance the interest of the game.

  In addition, when the 5 winning combination is won in the state where the 5 winning combination flag is carried over, the number of medals to be paid out is increased with different probabilities depending on whether the big bonus winning flag is carried over or not. By observing the number of medals to be paid when the winning combination is won, it is possible to indirectly estimate the degree of expectation of simultaneous winning of the big bonus, and it is possible to enhance the interest.

The present invention is not limited to the above-described embodiment, and can be modified or expanded as follows.
You may apply to the slot machine using a game ball.
You may apply to what is called an enclosing type slot machine which does not use an actual medal.
Not only the configuration in which two types of big bonuses are set, but also a configuration in which one type or three or more types of big bonuses are set.

While the number of payouts for the 5 hand combination is changed in the state where the 5 hand combination flag is carried over, the number of payouts for other small roles may be changed in the state where the 5 hand combination flag is carried over. For example, when a two-piece combination is won internally in a state where a five-piece combination flag is carried over, a payout lottery may be performed to vary the number of payouts by 2 to 15 pieces.
You may make it improve the internal winning probability of a small part and a bonus in the state which carries over the 5 piece combination flag. In this case, a privilege advantageous to the player that the internal winning probability is improved is given to the player. In short, it is only necessary to create a situation that is more advantageous for the player in the case of carrying the five-piece combination flag than in the case of not carrying the five-piece combination flag.
Not only is it possible to carry over the five-piece combination flag, but all the small combination flags may be carried over.
The carry-over possible period may be the number of games other than the number of games.

The carryover period may be defined by time instead of the number of games.
The end condition of the big bonus and regular bonus is not limited to the number of medals paid out reaching the specified number, for example, the number of medals inserted reaches the specified number, the number of occurrences of winning reaches the specified number of times, Other conditions such as the number of games reaching the specified number may be used.
