  • As shown in FIG. 12 (a), in the winning combination lottery table for slot machine (red), the random number value range is 0 to 20 for the “red seven” outcome, and the object to which the points are provided is set to “player”; specifically, slot machine (red). For the “blue seven” outcome, the random number value range is 21 to 31, and the object to which the points are provided is set to “match opponent”; specifically, slot machine (blue).
  • Therefore, when a match-style game is performed in slot machine (red), when the value of the random number sampled by the random number sampling circuit 56 is in the range of 0 to 20, the “red seven” outcome is won, and 100 points are provided to the same slot machine 1. When the sampled random number value is 21 to 31, the “blue seven” outcome is won, but the object to which the points are provided is set to “match opponent” this time, so 100 points are provided to slot machine (blue), which is the match opponent.
  • As shown in FIG. 12 (b), when a match game is performed in slot machine (blue), when the value of the random number sampled by the random number sampling circuit 56 is in the range of 0 to 20, the “blue seven” outcome is won, and 100 points are provided to the same slot machine 1. When the sampled random number value is 21 to 31, the “red seven” outcome is won, but the points this time are provided to “match opponent,” meaning that 100 points are provided to slot machine (red).
  • As described above, in the gaming system according to the embodiment, points corresponding to the winning combination can be acquired by a player who obtains a seven outcome having the same color as the slot machine he or she is using. When a seven outcome having a different color from that of the player's own slot machine is won, points are provided to the slot machine that corresponds to that outcome regardless of the player's own winning. Therefore, variability occurs in the process until the winner of the match-style game is determined, and variability also occurs in the match results.
  • A seven outcome having a different color from that of the player's slot machine will be referred to hereinafter as a “special outcome.”
  • In the slot machine 1 according to the embodiment, the winning combination lottery table used during execution of the match-style game is described, but the slot machine 1 may also perform a normal game that is played independently.
  • In the case of a normal game played by a player independently, the winning combination lottery table shown in FIG. 16 is used. FIG. 16 is a diagram showing the winning combination lottery table when a normal game is performed using slot machine (red).
  • As shown in FIG. 16, in the normal game, the “blue seven” outcome in which the object to which the points are provided is set to “match opponent” in the match game is changed so that points are provided to “player.”
  • The object to which the points are provided is thus set to “player” for all outcomes, whereby the normal game can be smoothly executed.
  • The main routine program executed in the slot machine 1 will be described based on FIG. 6. FIG. 6 is a flowchart of the main routine program. A case will be described in which slot machine (red) is used, but the same procedure applies when slot machine (blue) is used.
  • First, in step (hereinafter abbreviated “S”) 1, the start receive routine of FIG. 8 described hereinafter is performed. In this start receive routine (S1), the coins that become the necessary credit for performing the game in the slot machine 1 are received, and selection of either the single-player normal game or the match game played by a plurality of players is performed for the game executed in the slot machine 1. The process proceeds to S2 after the start receive routine (S1) is completed.
  • In S2, it is determined in the player's own slot machine 1 (slot machine (red)) and in the match opponent's slot machine 1 (slot machine (blue)) whether a match flag is present in the RAM 52 that indicates the desire to execute a match game. At this time, whether a match flag is present in the RAM 52 of the match opponent's slot machine 1 is determined based on a signal transmitted from the match opponent's slot machine 1 by the communication routine program described hereinafter.
  • When a match flag is present in the player's own slot machine 1, and a match flag is also present in the match opponent's slot machine 1, since both players desire a match game, the process proceeds to the match routine (S3) for executing the match game.
  • In S3, the match game is performed, the match results between the slot machines 1 are determined, and the award is provided based on the match results. After these routines are completed, the main routine program is completed.
  • When one of the players has not selected the match game, or when one of the players has selected the match mode, but the opponent player has not selected the match mode (S2: NO), since a single-player normal game is executed, the process proceeds to S4. This normal game is a game in which players compete for the highest total number of points provided based on winning combinations.
  • In S4, a lottery of winning combinations in the single-player normal game is performed (S4). The reels R are stopped and displayed according to the lottery results, and adding of points and other game routines are performed (S5). After such routines (S4, S5) pertaining to this single-player normal game are completed, the main routine program is completed.
  • In the slot machine 1 according to the embodiment, mutual communication between the player's own slot machine 1 and the other slot machine 1 is performed via the communication device 90 during execution of the main routine program. The communication routine program according to communication control between these slot machines 1 will be described with reference to FIG. 7.
  • As previously described, execution of the communication routine program shown in FIG. 7 is initiated in the CPU 50 together with initiation of the main routine program, and is executed while interrupt processing with respect to the main routine program is performed at predetermined time intervals.
  • In the slot machine 1 according to the embodiment, signals from the other slot machine 1 are continually received via the communication device 90 and the received content is stored in the RAM 52 during execution of the communication routine program.
  • When the communication routine program is initiated, first, it is determined in S101 whether a match flag is present in the RAM 52. The match flag is a flag stored in the RAM 52 when a match game is desired in the start receive routine (S1); specifically, when the match button 10 is operated.
  • When a match flag is present in the RAM 52 of the slot machine 1 (S101: YES), the process proceeds to S102, and a match potential signal indicating that the slot machine 1 desires a match game is transmitted to the other slot machine 1 (S102).
  • Consequently, in the aforementioned S2, the presence of a match flag can be recognized on the match opponent side by receiving this match potential signal by means of the communication device 90.
  • When a match flag is not present in the RAM 52 of the slot machine 1 (S101: NO), execution of the communication routine program is completed without transmission of a match potential signal. And after a predetermined time interval elapses, the communication routine program is again executed.
  • In S103, a timer synchronization signal is transmitted with respect to all of the slot machines 1 constituting the gaming system 100. This timer synchronization signal is a signal for synchronizing the start of timing by the aforementioned timer 74. After the timer synchronization signal is transmitted to the other slot machine 1, the process proceeds to S104.
  • In S104, it is determined whether a match completion flag is present in the RAM 52 of the slot machine 1 executing the match game. The match completion flag is a flag stored in the RAM 52 so that the match game is ended when a predetermined condition is satisfied during the match game in this gaming system 100.
  • When a match completion flag is present in the RAM 52 (S104: YES), a match completion signal for generating a match completion flag is transmitted to the other slot machine 1 (S105). After the match completion signal is transmitted, the process proceeds to S106. When a match completion flag is not present (S104: NO), the process proceeds as it is to S106.
  • In S105, the match completion signal transmitted to the other slot machine 1 is received by the other slot machine 1 that is constantly in a signal receiving state. The CPU 50 of the slot machine 1 that receives the match completion signal generates a match completion flag based on the match completion signal and stores the flag in the RAM 52.
  • In S106, it is determined whether a special outcome has been won. As described above, the “special outcome” is a seven outcome having a different color from that of the player's slot machine, and is an outcome for which the object to which the points are provided is set to “match opponent.
  • When a “special outcome” is won, specifically, when a special outcome flag described hereinafter is stored in the RAM 52 (S106: YES), award content is transmitted based on the winning combination lottery table so that the points corresponding to the special outcome are provided to the object, which is “match opponent” (S107). After the award content is transmitted to the slot machine 1 of the match opponent, the process proceeds to S108. When the “special outcome” is not won (S106: NO), the process proceeds as it is to S108.
  • More specifically, in S106 according to the embodiment, a “special outcome” win is determined to have occurred when the “blue seven” outcome is won using slot machine (red), and award content for providing 100 points is transmitted to the match opponent slot machine (blue).
  • A “special outcome” win is determined to have occurred when the “red seven” outcome is won using slot machine (blue), and award content for providing 100 points is transmitted to the match opponent slot machine (red).
  • In S108, the point information according to total points obtained during the match game by the player's slot machine is transmitted to the other slot machine joining in the match game.
  • Based on that the above point information is transmitted and received among the slot machines 1 joining in the match game together, the player's point information and the match opponent's point information are displayed on the liquid crystal display 4 of the slot machine 1. And after the match game is completed, by referring the point information of the players joining the match game, the winner determination of the match game is performed. After the point information is transmitted to the slot machines 1 joining in the match game, the communication routine program is completed. After a predetermined time elapses from this completion, the communication routine program is again executed while interrupt processing with respect to the main routine program is performed.
  • In the slot machine 1 constituting the gaming system 100 of the embodiment thus configured, the communication routine program mentioned above is executed while interrupt processing with respect to the main routine program is performed at predetermined time intervals. By this arrangement, comfortable gaming can be provided without time discrepancies between players occurring in the initiation and progress of the match game.
  • Each routine constituting the main routine program will be described in sequence with reference to the drawings. The start receive routine (S1) of the main routine program will first be described with reference to FIG. 8.
  • When execution of the main routine program is initiated, and the process proceeds to the start receive routine (S1), clearing of the RAM 52 and other initialization routines (S11) are first performed.
  • After the initialization routine (S11) is completed, the credit addition routine (S12) is performed in S12. In the credit addition routine (S12), the coins inserted from the coin insertion slot 9 are detected by the coin detector 73, and the number of credits is increased according to the number of coins inserted. Credit is spent by making any bet on the active pay line L during a single-player normal game and a match-style game.
  • After the credit addition routine (S12) is completed, it is determined in S13 whether the current number of credits is 20 or higher. In the gaming system according to the embodiment, the number of credits must be 20 or higher in order to execute a match game. By setting a credit number of 20 or higher as a condition in this manner, a match game can be prevented from ending in a short time, and the match game can be enjoyed for a certain period of time.
  • When the current number of credits is 20 or higher (S13: YES), the input of the match button 10 is enabled, and the process proceeds to S14. At this time, it becomes possible for the player to select a single-player normal game or a match-style game.
  • When the number of credits is 20 or lower (S13: NO), the start receive routine (S1) is ended with the input of the match button 10 disabled. Consequently, in this case, use of the slot machine 1 is limited to the single-player normal game.
  • In S14, which occurs when the number of credits is 20 or higher, it is determined whether a match mode is selected. Specifically, this determination is made based on whether there is an input from the match button 10, and when there is an input from the match button 10 (S14: YES), the CPU 50 generates a match flag and stores it in the RAM 52 (S15). After the match flag is stored in the RAM 52, the start receive routine (S1) is completed, and the process proceeds to S2.
  • When there is no input from the match button 10 (S14: NO), it is determined that the player desires a single-player normal game, the start receive routine (S1) is completed without generation of a match flag, and the process proceeds to S2.
  • The match routine program will next be described with reference to FIG. 9. This match routine program is a program executed in the match routine (S3), performed when there is a plurality of players who desire a match game.
  • When the process proceeds to the match routine (S3), the timer 74 synchronization routine in S21 is first performed. In the timer synchronization routine (S21), a routine is performed for synchronizing the start of timing by the timer 74 between the slot machines 1 performing the match game based on the timer synchronization signal received in the aforementioned communication routine program. Specifically, the timer synchronization signal transmitted from the match opponent slot machine 1 is compared with the players own timer 74 data, and the time difference between the two machines is determined. The start of timing by both timers 74 is synchronized by causing processing to wait according to the time difference of whichever timer 74 is ahead.
  • In S22, processing is put on standby according to the time difference derived from the timer synchronization signal, as described previously. Therefore, in S22, processing is put on standby for a predetermined time according to the time difference only when the timer 74 is ahead.
  • When the predetermined time has elapsed, and the timers 74 of the slot machines 1 performing the match game are synchronized, measurement of the match game time limit (three minutes, for example) is initiated (S23).
  • In the present embodiment, the timer 74 is synchronized by causing processing to stand by according to the time difference, but the timer 74 may also be synchronized by simultaneously resetting both the timers 74.
  • In S24, it is determined whether a match completion flag is present. The match completion flag is a flag stored in the RAM 52 based on a match completion condition monitoring program described hereinafter. When a match completion flag is present (S24: YES), the process proceeds to the winning award provision routine (S27), and the match game is completed. When there is no match completion flag (S24: NO), the process proceeds to S25, and the match game is continued.
  • In S25, the lottery routine is performed. In the lottery routine (S25), the player determines the bet amount of one game constituting the match game, and a lottery of the outcome of that game is performed. This lottery routine will be described in detail hereinafter with reference to the drawings.
  • After the lottery routine (S25) is completed, the process proceeds to the match game routine (S26). The match game routine is a routine for initiating rotation of the reels R, controlling stoppage thereof based on the lottery results in S25, computing points based on a winning combination, and performing other tasks. This match game routine will be described hereinafter with reference to the drawings.
  • After the match game routine (S26) is completed, the process returns to S24, and the match game is continued.
  • As previously described, when a match completion flag is present (S24: YES), the process proceeds to the winning award provision routine (S27). This winning award provision routine (S27) is a routine for comparing the number of points between the slot machines 1 that performed the match game, and providing an award to the winner having the most points according to the number of points acquired. This winning award provision routine will be described in detail hereinafter with reference to the drawings.
  • After the winning award provision routine (S27) is completed, the match routine program ends, and the process returns to the main routine program.
  • In the slot machine 1 according to the embodiment thus configured, a plurality of programs are executed while interrupt processing with respect to the match routine program is performed at predetermined time intervals. The match completion condition monitoring program, which is one of the abovementioned plurality of programs and which relates to completion of the match routine program, will be described with reference to FIG. 10.
  • The match game according to the embodiment is forced to end when any one of two conditions is satisfied. The ending conditions for the match game are the following two conditions: “the number of credits in any one of the slot machines 1 participating in the match game becomes zero,” and “the time limit (three minutes) of the match game has elapsed.”
  • By this match completion condition monitoring program, the slot machine 1 is monitored whether any of the abovementioned two conditions is satisfied during a match game.
  • Therefore, the process proceeds to the match routine (S3), execution of the match completion condition monitoring program is initiated by the CPU 50, and processing is performed at predetermined time intervals. First, in S31, it is determined whether the number of credits of the slot machine 1 is zero. When the number of credits is not zero (S31: NO), the process proceeds to S32. In S32, it is determined whether the time period elapsed since the start of the match game has reached the time limit (three minutes in the embodiment). When the results of referencing the timer 74 show that the time limit has not elapsed (S32: NO), the process returns to S31 and the above processes are repeated till the match game is completed.
  • When the number of credits of the slot machine 1 has reached zero (S31: YES), or in the subsequent S33 to which the process proceeds when the predetermined time (three minutes) has elapsed (S32: YES), the CPU 50 generates a match completion flag based on the match completion condition being satisfied, and stores the match completion flag in the RAM 52.
  • After the match completion flag is stored in the RAM 52 (S33), the match game and the match completion condition monitoring program are both ended.
  • As described above, the match completion flag generated by the match completion condition monitoring program is used in S24 during the match routine, and leads the slot machine 1 towards the routine relating to completion of the match game.
  • The lottery routine program executed in the lottery routine (S25) in the match routine program (see FIG. 9) will first be described with reference to FIG. 11.
  • In the lottery routine program as shown in FIG. 11, first, in S41, it is determined whether the spin button 12 or the like has been operated. In other words, in S41, the player performs the operation for determining the number of credits bet with respect to the active pay line L using the 1-BET button 11, the MAX-BET button 13, and the like, and performs the operation for initiating rotation of the reels R by the input of the spin button 12.
  • When the spin button 12 or the like is not operated (S41: NO), processing stands by until the spin button 12 or the like is operated. When the spin button 12 or the like is operated, the bet amount with respect to the active pay line L is determined, and the operation for initiating rotation of the reels R is performed (S41: YES), the process proceeds to S42 and the lottery of winning combination in the present game is executed.
  • In the outcome lottery routine (S42), the lottery of outcomes is performed using the winning combination lottery table shown in FIGS. 12 (a), 12 (b) and the random number sampling circuit 56. Specifically, it is determined to which random number range corresponding to each outcome of the winning combination lottery table (see FIGS. 12 (a), 12 (b)) a random number sampled by the random number generator 55 and the random number sampling circuit 56 belongs, and the lottery results are determined based on this determination.
  • In S43, a symbol determination routine is performed for determining how the combination of symbols constituting the winning combination determined by the outcome lottery routine (S42) is formed from the symbols formed on the peripheral faces of the reels R. When a winning combination is won, all the same symbols are stopped and displayed. Therefore, when a “miss” is selected, at least one of the symbols stopped on the active pay line L in the reels R is different from the others.
  • At this time, there is no case in which the stopped and displayed symbols consist only of a mixture of “red seven 94” and “blue seven 97.” In other words, there is no stopped display such as “red seven 94,” “red seven 94,” and “blue seven 97” on the active pay line L, which appears as if a seven outcome is won. This is to prevent the player from confusing such an outcome with a winning combination of “sevens.”
  • After the symbol determination routine (S43) is completed, the lottery routine program is ended, and the process proceeds to S26 of the match routine program.
  • The match game routine program executed in S26 of the match routine program will be described with reference to FIG. 13.
  • When the transition to the match game routine program is made, first, in S51, the rotation routine for initiating rotation of the reels R is performed. After the reels R have been rotated for a certain period of time, a stopping control routine (S52) for stopping the symbol determined in the symbol determination routine (S43) on the active pay line is performed. After the stopping control routine (S52) is finished, the process proceeds to S53.
  • In S53, it is determined whether a “special outcome” has been won. Specifically, it is determined in the case of slot machine (red) whether the outcome “blue seven” has occurred, and in the case of slot machine (blue), whether the outcome “red seven” has occurred. In other words, such determination is performed based on whether or not the random number value sampled in the outcome lottery routine (S42) lies in a range of 21˜31.
  • When a “special outcome” has occurred (S53: YES), the process proceeds to S54, a special outcome award flag indicating the winning of a “special outcome” is generated, and the flag is stored in the RAM 52 (S54). Since this special outcome award flag is stored in the RAM 52, it is determined that a special outcome has been won in the routine of S106 in the aforementioned communication routine program, and award content corresponding to the special outcome is transmitted to the other slot machine 1 (S107). After the special outcome award flag is stored in the RAM 52, the process proceeds to S55.
  • When “special outcome” is not won (S53: NO), the process proceeds as such to S55.
  • In S55, the award content receiving routine is performed. In the award content receiving routine, the “special outcome” award “100 points” is added to the points that are to be added to the points of the slot machine 1 based on the reception results of the award content transmitted in S107 of the aforementioned communication routine program.
  • In S56, the point assessment routine (S56) is performed for adding the sum of the points relating to the “special outcome” added in S55 and the points added based on the lottery results in the player's own slot machine 1 to the current number of points obtained in the player's own slot machine 1. After the point assessment routine (S56) is completed, the match game routine (S26) is ended, and the process returns to the match routine program.
  • Concretely describing on the basis of an example, in a case that the slot machine 1 of the match opponent is the slot machine (blue) and the “red seven” outcome is won (S53: YES), as the award content, it is transmitted to the player's won slot machine (red) the award content to give 100 points thereto (S54). At that time, in the player's own slot machine 1 (red), if the winning combination of “3BAR” is won, the slot machine 1 (red) receives the award content (signal to give 100 points) from the slot machine (blue) (S55), and such 100 points given from the other slot machine 1 as the award content and 30 points of the winning combination of “3BAR” are added to the total points obtained at present (S56).
  • The winning award provision routine program executed in the winning award provision routine (S27) performed at the end of the match game in the match routine program will next be described with reference to FIG. 14.
  • When the transition to the winning award provision routine (S27) is made, first, in S61, the point information of the opponent is read, which is the information transmitted in S108 of the communication routine program and stored in the RAM 52 of the slot machine 1. The winner determination routine (S62) for determining the winner of the match game is then performed by comparing the point information of the player with the point information of the opponent read from the RAM 52, and computing the difference between the opponent's points and the player's points.
  • In S63, the content of the award paid out to the winner is determined based on the results of the winner determination routine (S62) and the winning award determination table (see FIG. 15).
  • The winning award determination table will be described. Credit is provided to the winner of the match game in the gaming system according to the embodiment. The credit thus provided also varies according to the point difference between the player and the match opponent.
  • As shown in FIG. 15, 100 is added to the number of credits of the winning slot machine 1 when the point difference between the participants in the match game is 1000 points or greater. Therefore, by operating the payout button 7 at the end of the game, coins are paid out according to the amount of credit remaining. When the point difference between the participants in the match game is 500 points or greater and less than 1000 points, 50 is added to the number of credits of the winning slot machine 1. When the point difference between players is 10 points or greater and less than 500 points, 20 is added to the number of credits of the winning slot machine 1.
  • After the content of the winning award provided to the winner is determined according to the point difference between the participants in the match game in this manner, the process proceeds to S64.
  • In S64, it is determined whether the slot machine 1 won the match. In other words, a determination is made based on the determination result of the winner determination routine (S62) for determining whether the player has more points compared with the match opponent's points.
  • When the slot machine 1 is defeated (S64: NO), a message indicating loss of the match is displayed on the liquid crystal display 4, and the loss is reported to the player (S66). When the slot machine 1 wins (S64: YES), a celebration message indicating a win is displayed on the liquid crystal display 4 (S65). After the winning screen is displayed on the liquid crystal display 4, the winning award determined in the winning award determination routine (S63) is added to the player's credit (S67).
  • After the winning award is provided (S67), both the winning award provision routine program and the match routine program are ended.
  • In the gaming system according to the embodiment, not only can the aforementioned match-style game be played, but a single-player normal game can also be played. The processing relating to the single-player normal game will be described herein with reference to the drawings.
  • As previously described, a single-player normal game is performed when the player of the slot machine 1 does not desire a match game in the slot machine 1 according to the embodiment, or when the player of the slot machine 1 desires a match game, but there is no other player present who desires to participate in a match game as the match opponent (S2: NO).
  • In this situation, the process first proceeds to the lottery routine (S4). Since this outcome lottery routine performs basically the same control as the previously described lottery routine (see FIG. 11) of S25 in the match routine program, detailed description thereof is omitted. This lottery routine (S4) differs from the lottery routine (S25) in the match routine program in the winning combination lottery table used in the outcome lottery routine. The winning combination lottery table used in the lottery routine (S4) is different form the table shown in FIGS. 12 (a), 12 (b) which is used in the match game, the winning combination lottery table used in the lottery routine (S4). In the winning combination lottery table, the object to be provided with points for all outcomes is set to “player” (see FIG. 16).
  • After the bet amount for the active pay line L, the outcome in the current game, and the symbol constituting the outcome are determined by the lottery routine (S4), the game routine is performed in S5. The game routine (S5) in the single-player normal game will be described with reference to FIG. 17.
  • When the transition is made to the game routine in the single-player normal game, first, in S71, the rotation routine for initiating rotation of the reels R is performed. After rotation of the reels R is initiated, and a predetermined period of time has elapsed, a stopping control routine (S72) is performed for stopping the outcome determined as a result of the lottery routine (S4), and the symbols constituting the outcome, on the active pay line L.
  • After the stopping control routine (S72) is finished, the points provided to the slot machine 1 are read based on the winning combination lottery table (see FIG. 16) and the outcome determined in the lottery routine (S4), and the point assessment routine (S73) is performed for adding the points thus read to the slot machine's current points. After the point assessment routine (S73) is completed, the game routine (S5) is completed, and the single-player normal game is ended.
  • As described above, in the gaming system 100 according to the embodiment, when a match game is executed using the slot machines 1 constituting gaming system 100, and the “special outcome” is won, points according to the special outcome are not given to the player's own slot machine 1 but are given to the match opponent. Concretely describing, in a case that the match is conducted using the slot machine 1 (red) and the “blue seven” outcome which is the special outcome is won, points are not given to the player's own slot machine (red) but are given to the slot machine (blue) which is the match opponent.
  • As described, based on that points obtained according to that the winning combination is won and the object to which such points are given are determined corresponding to the winning combination, it will occur variability that the game result becomes advantageous or disadvantageous. As a result, variability concerning with victory or defeat of the match will occur, therefore not only skillful player but also skill-less player can enjoy interest of the match.
  • The present invention is in no way limited by the embodiment described above, and may include various modifications in ranges that do not depart from the intended scope thereof.
  • For example, a case is described in the above embodiment in which the gaming system 100 is composed of two slot machines 1, but the gaming system 100 may be formed using numerous slot machines 1.
  • In this case, based on that “seven” outcome with color corresponding to each of the slot machines is added to the winning combination lottery table, the match game similar to the match game according to the embodiment can be conducted over plural slot machines. For example, in addition to the symbols of “red seven” and “blue seven”, symbols of “yellow seven” and “green seven” are added to each of the reels R, and further outcomes of “yellow seven” and “green seven” are added as the special outcome to the winning combination lottery table, thereby the match game can be conducted over four slot machines 1 of “red”, “blue”, “yellow” and “green”.
  • The match game described in the abovementioned embodiment is one in which a slot machine 1 and another slot machine 1 compete with each other one at a time, but teams of each color of slot machine 1 may also be formed, and a match game may be played between teams.
  • In the embodiment, the object to which points of “special outcome” is directed to a slot machine 1 such as the slot machine (red) or the slot machine (blue). However, points may be given to all of the other slot machines participating in the match game except for the player's own slot machine 1. Thereby, new interest can be given to the match game.
