JP 2004-350799 A

  However, in the conventional slot machine described above, the notification image is displayed on the image display means to notify the winning of a special role such as a big bonus, but many slot machines spread in the market use this means. Since it has been adopted, it has become a conventional means and lacks the freshness of the player, and there has been a problem that the effect of raising the expectation is being reduced.

  On the other hand, a slot machine has conventionally been provided with a plurality of bet switches to which bets (bets) of game media such as medals are assigned, and 1 to 3 game media are selected by operating each bet switch. I started to bet.

  However, in conventional slot machines, the number of bets set when each bet switch is operated is always constant, and these bet switches and lamps for displaying the number of bets are used for purposes other than betting game media. It was never done. For this reason, the betting action of the game medium in the conventional slot machine does not cause the player to expect or announce any special role such as a big bonus in a series of repeated games.

  The present invention has been made in view of the above problems, and provides a slot machine that can greatly aspire a player's expectation by notifying the winning of a special role by an unprecedented novel means. With the goal.

  In order to achieve the above-described object, the slot machine according to the present invention uses a process from inserting a game medium as a bet target and rotating and stopping a plurality of reels displaying a plurality of symbols as one unit. A slot machine capable of repeatedly performing a game, wherein a part lottery means for performing a part lottery for determining one part from a part including a special part, and a bet control means for detecting and setting the number of bets on the game medium; A bet number display means for displaying based on the bet number set by the bet control means, and the bet control means has a bet different from the detected bet number when the special combination is won in the previous game. An effect of setting the number is performed.

  In such a slot machine of the present invention, when a special role is won, for example, a bet number different from the number assigned to the bet switch operated by the player is set, and this different bet number is displayed (this) Is referred to as a bet number effect), the player is informed that a special role has been won. By adopting such a notification means that imitates the malfunction, the player can not be sure that the slot machine malfunctions or that the special role is elected, and this is won for the special role. This leads to a sense of expectation.

  Here, the “game medium” is a medium that is inserted into the slot machine in order to play a game, such as coins, medals, and chips. In addition, as long as this object can be achieved, it is not limited to an actual object, and for example, an electromagnetically acting one such as a magnetic card can be applied.

  “Inserting” a game medium includes that the player actually inserts a game medium such as a coin into a game medium slot provided in the slot machine. In addition, the use of a predetermined number of game media credited in advance as the storage medium of the slot machine is also included.

  As for “reel on which a symbol is displayed”, in addition to a real reel that is physically rotated and stopped by a motor or the like, a virtual reel using CG (computer graphic) displayed on a display device or the like. Is also included.

  The “bet number display means” includes a lamp such as a light bulb or LED that can display the bet number directly or indirectly, a segment number display, and a CRT (Cathode Ray Tube) or LCD (Liquid Crystal Display). A display device and the like are also included.

  “Position” includes, for example, a “general role” that pays out a predetermined number of game media when winning a prize, and a “special role” that can be transferred to a “special game” that advances the game in an advantageous manner for the player. In addition, “re-game” that can re-execute a game without inserting a game medium is included. Various other combinations can be added according to the game mode.

  The “general combination” is a combination in which a predetermined number of game media are paid out when a general combination is won by lottery and a symbol corresponding to the general combination is won.

  The “special role” includes a “first special role” that can be transferred to a “first special game” in which a game in which a predetermined role is selected with a high probability by lottery is performed a predetermined number of times under a certain condition, A “second special role” that can be transferred to a “second special game” in which at least one of a game and a game corresponding to the first special game can be played is included.

  Here, the first special combination is a combination transferred to the first special game which is one of the special games, and includes a combination called a regular bonus combination (hereinafter referred to as RB combination). In the first special game, a game in which a predetermined combination is won with a high probability can be performed a predetermined number of times under a certain condition. The second special combination is a combination that is transferred to the second special game, which is one of special games, and includes a combination called a big bonus combination (hereinafter referred to as a BB combination). The second special game is a game in which at least one of the general game and the game corresponding to the first special game can be played until a predetermined game medium payout number is reached.

  “Re-playing” means “re-playing” in which a re-playing role can be re-executed without throwing in game media when the re-playing role is won in the role lottery and the symbol corresponding to the re-playing role is stopped and won. (Also referred to as “replay”).

  In the “role drawing” for determining one combination, for example, it is desirable to generate a random number and determine one winning combination based on the value. Regarding the generation of random numbers, it may be generated on software such as a random number generator or a computer.

  Preferably, in the slot machine according to the present invention described above, whether or not the bet control means performs an effect of setting a bet number different from the detected bet number when the special combination is won in the previous game. You may make it draw lots.

  In such a slot machine of the present invention, even when a special role is won in the previous game, the fact that the special role has been won't necessarily be notified, even when a special role is won. Uncertainty is added that notification may not be made. The player's sense of expectation can be increased by the uncertainty of the presence or absence of such notification.

  Furthermore, preferably, when the special combination is not won in the previous game, the bet control means determines whether or not to perform an effect of setting a bet number different from the detected bet number. The winning probability of performing the effect in the lottery may be set lower than the winning probability of performing the effect in the lottery when the special combination is won.

  In such a slot machine of the present invention, even when the special game is not won in the previous game, there is an uncertainty that the same notification may be given as when the special game is won. The Due to such indefiniteness of notification, the player's sense of expectation can be further increased.

  According to the slot machine of the present invention described above, when a special role is won, for example, a bet number different from the number assigned to the bet switch operated by the player is set, and this different bet number is displayed. The player can be notified that the special role is won. By adopting such a notification means that imitates the malfunction, the player can not be sure that the slot machine malfunctions or that the special role is elected, and this is won for the special role. This is effective in increasing the player's expectation that the player is doing.

  Hereinafter, a slot machine according to an embodiment of the present invention will be described in detail with reference to the drawings.

The CPU 206 reads image data, character data, and the like stored in the ROM 208 in accordance with the control information supplied from the main control circuit 100 and supplies the data to the display driving device 220. Thereby, on the image display device 70, the image data is displayed as an effect screen, and the character data is displayed as a message.

  Also connected to the input / output bus 204 is a lamp driving circuit 218 for driving the respective lamps of the effective line display units 24a to 24e. The CPU 206 issues a drive command to the lamp drive circuit 218 in accordance with the control information supplied from the main control circuit 100, and drives each lamp of the effective line display units 24a to 24e to be lit in response to the drive command.

  The input / output bus 204 is also connected with a lamp driving circuit 223 for lighting the bet number display lamps 51a to 51c. The CPU 206 issues a drive command to the lamp drive circuit 223 according to the control information supplied from the main control circuit 100, and turns on the bet number display lamps 51a to 51c according to the drive command.

  Also connected to the input / output bus 204 is a display drive circuit 224 for driving the credit number display unit 53 to light. The CPU 206 issues a drive command to the display drive circuit 224 in accordance with the control information supplied from the main control circuit 100, and drives each LED constituting the credit amount display unit 53 to turn on and drive a predetermined number in accordance with the drive command. Display.

  Also connected to the input / output bus 204 is a display drive circuit 225 for driving the acquired number display section 54 to light.

Display.

  The input / output bus 204 is also connected with a speaker drive circuit 222 for driving the speaker 64. The CPU 206 reads out audio data stored in the ROM 208 in accordance with control information supplied from the main control circuit 100 and supplies the data to the speaker drive circuit 222. By doing so, a predetermined sound is emitted from the speaker 64.

[Description of control processing]
<Description of Control Processing of Slot Machine 10>
Hereinafter, various controls performed by the control unit of the slot machine 10 described above will be described in detail with reference to flowcharts.

  FIG. 5 shows a main routine of control processing performed in the main control circuit 100 of the slot machine 10. 6 to 13 show subroutines that are control processes performed in the main routine.

  FIG. 6 shows a bet number normal processing subroutine performed by the bet control means 400. FIG. 7 shows a part lottery processing subroutine for performing part lottery performed by the part lottery means 410 and flag-on processing performed following the part lottery. FIG. 8 shows a reel fluctuation / stop subroutine in which the reel controller 420 performs control for rotating and stopping the reel. FIG. 9 shows a flag-off process subroutine which is a control process after the symbol is stopped by the reel fluctuation / stop subroutine. FIG. 10 shows a winning combination process subroutine which is a part of the control process of the flag off process subroutine. FIGS. 11 to 13 show a bet number effect processing subroutine performed by the bet control means 400.

  In the control process described below, the slot machine 10 is activated in advance, and variables used in the main control circuit 100 and the sub control circuit 200 of the slot machine 10 described above are initialized to predetermined values and operate in a steady state. It shall be.

<Description of main routine>
The control process of the main routine will be described using the flowchart of FIG. The main routine shows a control process when a unit game is performed once until a process based on a result of rotating and stopping a plurality of reels displaying a plurality of symbols.

  First, it is determined whether or not the re-gaming state is set and the re-gaming state is set (step S11). Note that the processing for setting the re-gaming state is performed in step S79 of the winning combination processing subroutine shown in FIG. 10, for example, as will be described later.

  When it is determined that the replay state is not set (NO), it is determined whether or not the BB combination that is one of the special combinations is won (step S12). If it is determined in this step S12 that the BB combination is not won (NO), the process proceeds to a bet number normal processing subroutine by the bet control means 400 (step S13). In this bet number normal processing subroutine, the bet number is detected based on the number of game media inserted into the game medium insertion port 38 or the operation signal from each of the bet switches 32, 34, 36, and the bet number is set. Normal processing is performed. Details of this subroutine will be described later with reference to the flowchart of FIG.

  If it is determined in step S12 that the BB combination is won (YES), the process proceeds to a bet number effect processing subroutine by the bet control means 400 (step S20). In this bet number effect processing subroutine, effect processing for setting a bet number different from the actually detected bet number is performed in order to notify that the BB combination has been won. Details of this subroutine will be described later with reference to the flowcharts of FIGS.

  On the other hand, when it is determined in step S11 that the re-gaming state is set (YES), the re-gaming state setting is canceled (step S14), and a gaming medium is newly inserted or credited gaming medium The processing that can play the game again is performed without consuming. In such a re-gaming state, the bet number of the game when the re-game player is won is stored in the RAM 110, and the re-game is performed using the bet number at this time.

  Next, it is determined whether or not the start switch 50 has been turned on by the player (step S15). If it is determined that the start switch 50 is not turned on (NO), the process of step S15 is repeated. On the other hand, if it is determined that the start switch 50 has been turned on (YES), the routine proceeds to a winning lottery process subroutine (step S16).

  In the part lottery processing subroutine of step S16, the part lottery process by the part lottery means 410 is performed, and the flag on process for turning on the RB flag, the BB flag, the replay flag, and the corresponding general part flag is performed according to the winning part. . Details of this subroutine will be described later with reference to the flowchart of FIG.

  Subsequent to the winning lottery processing subroutine (step S16), based on the winning lottery result, a reel fluctuation / stop subroutine (step S17), which is a control process related to the movement of the reels to be stopped after rotating the reels 40L, 40C, 40R, is performed. . This reel fluctuation / stop subroutine is performed by the reel control means 420, and details of this subroutine will be described later with reference to the flowchart of FIG.

  Next, after the reels are stopped by the reel fluctuation / stop subroutine, a winning symbol determination is performed, and a flag-off processing subroutine (step S18) for performing a flag-off process based on the determination result is performed. Details of this subroutine will be described later with reference to the flowcharts of FIGS.

  Then, a payout process (step S19) for paying out a predetermined number of game media corresponding to the winning combination is performed based on the results of the winning combination lottery and winning symbol determination. In this payout process, it is possible to actually pay out game media from the game media payout outlet 62, but instead of paying out, it is also possible to credit a predetermined number of game media. The unit game is completed by the above control process. Then, by repeating the control process shown in this main routine, the player can play a plurality of unit games.

<Bet number normal processing subroutine>
The bet number normal processing subroutine will be described in detail with reference to FIG. First, it is determined whether or not a game medium has been inserted (step S21). If it is determined in this determination that a game medium has been inserted (YES), the process proceeds to step S24, and the inserted number counted by the game medium counter installed below the game medium insertion port 38 is detected as the bet number. . However, when the number of game media exceeding the specified number (three in this embodiment) is inserted, the game media exceeding the specified number is stored in the RAM 110 as the number of credits.

  If it is determined in step S21 that the game medium is not inserted (NO), the process proceeds to step S22 to determine whether there is a credited game medium. If it is determined in this determination that there is no credited game medium (NO), the process returns to step S21 again, and the determination process of step S21 and the next step S22 is repeated.

  If it is determined in step S22 that there is a credited game medium (YES), whether an operation signal (bet operation signal) for any of the bet switches 32, 34, 36 has been received next. It is determined whether or not (step S23). If it is determined in this determination that the bet operation signal has not been received (NO), the process returns to step S21 again, and the determination processing from step S21 to step S23 is repeated. If it is determined in step S23 that a bet operation signal has been received (YES), the process proceeds to step S24, and the number of bets is detected from the received bet operation signal. In either case of inserting a game medium or using a credited game medium, the detected bet number is stored in the RAM 110 as a new bet number, and when using a credited game medium, The number of detected bets is subtracted from the number of game medium credits (step S25). Thereafter, the bet number and credit number signals are transmitted to the sub-control circuit 200 (step S26).

<Role lottery processing subroutine>
The combination lottery process and the flag-on process will be described in detail with reference to FIG. First, it is determined whether or not the game mode is an RB game (step S31). When it is determined that the game mode is RB game (YES), the RB lottery table stored in the ROM 108 is read (step S32). Here, an example of the RB lottery table is shown in FIG.

  In the RB lottery table, a general combination with symbol numbers 1 to 3 and a deviation of symbol number 4 are set. For example, when general combination 2 is won, all three reels have bell symbols. It is set to win. In the combination lottery performed in step S36 described later, the probability that the general combination 2 wins is 1 / 1.03, which is set very high. Therefore, during the RB game, the possibility of winning the general combination 2 is very high. Conversely, the probability of loss is about 1 / 212.49, which is set very low.

  If it is determined in step S31 that the game mode is not RB game (NO), it is next determined whether or not the game mode is BB game (step S33). When it is determined that the game mode is BB game (YES), the lottery table for BB operation stored in the ROM 108 is read (step S34). Here, FIG. 17 shows an example of the BB operation lottery table.

  The BB operating lottery table is a lottery table used when the game mode is in the BB game and not in the RB game. In the BB operation lottery table, an RB combination of symbol number 1, a general combination of symbol numbers 2 to 4, and a deviation of symbol number 5 are set. Here, as compared with the general lottery table when BB is not activated (see FIG. 18), the lottery table when BB is activated is set to have no BB combination and re-playing combination.

  The RB combination with the symbol number 1 is set to win when the winning probability in the combination lottery is 1/4 and the symbols of the BAR are aligned on all three reels. In the general lottery table when the BB is not used in the normal gaming state, the winning probability of the RB role in the role lottery is 1/312. During the BB game, the probability of winning the RB role is very high compared to the normal time. Is set high.

Further, the general combination 1 with the symbol number 2 is set to win when the winning probability in the combination lottery is 1 / 81.9 and all three reels have the watermelon symbols. The general combination 2 with the symbol number 3 is set to win when the winning probability in the combination lottery is 1/20 and all three reels have the bell symbol. If the winning combination probability in the winning combination lottery is 1 / 81.9 and the symbol of the first reel is cherry, any of the symbols of the remaining reels is Is also set to win.

  If it is determined in step S33 that the BB game is not in progress (NO), the BB non-operating general lottery table stored in the ROM 108 is read (step S35). FIG. 18 shows an example of the general lottery table when BB is not operating.

  The BB non-operating general lottery table is a lottery table used in a normal game state that is not a special game (RB game, BB game), the BB role of symbol number 1, the RB role of symbol number 2, and symbol numbers 3 to 3 A general combination of 5, a re-playing combination of symbol number 6, and an off-set of symbol number 7 are set.

  In the BB non-operating general lottery table of FIG. 18, the winning probability and the symbol combination in the symbol lottery are set for the symbol BB symbol 1, and the maximum number of winnings is set to 451 as the end condition. It is. In addition, the probability in the extra lot drawing is set to about 1 / 1.28.

  As described above, after the lottery table corresponding to the state of the game is read out, the lottery for acquiring the random number and performing the lottery determination is performed (step S36).

  Then, as a determination result, it is determined whether or not the RB combination is won (step S37). When it is determined that the RB combination has been won (YES), the RB flag is set to ON (step S38), the process proceeds to step S48, and the selected symbol number and symbol data are stored in the RAM 110 (step S48).

  If it is determined in step S37 that the RB combination is not won (NO), it is next determined whether or not the BB combination is won (step S40). When it is determined that the BB combination is won by the combination lottery (YES), the BB flag is set to ON (step S41), the process proceeds to step S48, and the selected symbol number and symbol data are stored in the RAM 110 (step S48).

  If it is determined in step S40 that the BB role has not been won (NO), it is determined whether or not any of the general role 1, the general role 2, or the general role 3 is won (step S40). S42). When it is determined that one of the general roles 1 is won (YES), the corresponding general role flag is set to ON (step S43), the process proceeds to step S48, and is stored in the RAM 110 (step). S48).

  Next, when it is determined in step S42 that no general combination has been won (NO), it is determined whether or not a re-playing combination has been won (step S44). If it is determined that the re-game combination is won by the combination lottery (YES), the re-game flag is turned on (step S45), the process proceeds to step S48, and is stored in the RAM 110 (step S48).

  Furthermore, if it is determined in step S44 that the re-game is not won (NO), any of the general roles 1, 2, or 3 in the RB game is won. It is determined whether or not it has been done (step S46). When it is determined that one of the general roles in the RB game is won (YES), the corresponding general role flag in the RB game is turned on (step S47), the process proceeds to step S48, and is stored in the RAM 110 (step S48). .

  Here, if it is determined in step S46 that any of the general combination 1, general combination 2, or general combination 3 in the corresponding RB game is not won (NO), the flag-on process is not performed. Then, the process proceeds to step S48 as it is.

  As described above, after performing a series of processes related to flag-on, in step S48, the symbol number and control symbol data corresponding to the winning combination in the winning lottery are read from the ROM 108 and used in a reel fluctuation / stop subroutine described later. This data is stored in the RAM 110. The combination lottery processing subroutine is thus completed.

<Explanation of reel fluctuation / stop subroutine>
Next, in the main routine of FIG. 5, when the combination lottery processing subroutine (step S16) is completed, a reel fluctuation / stop subroutine (step S17) is then performed. The reel rotation and stop control will be described with reference to FIG.

  First, the symbol number and control symbol data stored in step S48 of FIG. 7 are read (step S51). Then, it is determined whether or not a predetermined shortest time has elapsed (step S52). When it is determined that the shortest time has not elapsed (NO), the determination process in step S52 is repeatedly executed. As a result, the rotation of the reel, which is the next process, cannot be started until the shortest time has elapsed. By this control, the number of games played in a certain time is controlled to be within a predetermined number.

  When it is determined that the shortest time has elapsed (YES), a reel rotation start signal is transmitted (step S53). Based on this signal, the motor drive circuit 114 operates to start the rotation of the motors 80L, 80C, 80R, and the reels 40L, 40C, 40R start to rotate.

  Next, it is determined whether or not the reel that has started rotating is rotating at a constant speed (step S54). When it is determined that the rotation of the reel has not yet reached a constant speed (NO), the determination process in step S54 is repeated. As a result, the reel stop control as the next step cannot be performed until the rotation of the reel reaches a constant speed.

  If it is determined that the reel is rotating at a constant speed (YES), it is next determined whether or not a reel stop signal has been received (steps S55 to S57).

  The reel stop signal is transmitted when the player pushes any one of the stop switches 52L, 52C, 52R. For example, when the stop switch 52L for the first reel is pushed, a first reel stop signal is transmitted, and stop control of the motor 80L that rotates the first reel 40L is performed. Similarly, when the stop switch 52C for the second reel is pushed, a second reel stop signal is transmitted to stop the motor 80C for rotating the second reel 40C, and the third reel When the stop switch 52R is pushed, a third reel stop signal is transmitted to stop the motor 80R that rotates the third reel 40R.

  When it is determined that none of the first reel stop signal, the second reel stop signal, or the third reel stop signal is received, the control relating to the stop is not performed, but the first reel stop signal, the second reel stop signal, or the third reel stop signal is not performed. When it is determined that any one of the reel stop signals has been received, the process proceeds to the next step S58.

  In step S58, it is determined whether or not there is a winning combination. If it is determined that there is a winning combination, if there is a symbol corresponding to the winning combination within the reel stop possible range, the symbol is stopped on the active line. Let

  Then, the process proceeds to step S59, where it is determined whether or not all the reels are stopped. When it is determined that all the reels are not stopped (NO), the process returns to step S55 and is repeated until all the reels are stopped. On the other hand, when it is determined that all the reels are stopped (YES), this subroutine is finished as it is.

<Description of flag off processing subroutine>
In the main routine of FIG. 5, when the reel fluctuation / stop subroutine (step S17) is completed, a flag-off process subroutine (step S18) is performed. The flag off process will be described with reference to FIG.

  First, it is determined whether or not the gaming state is RB gaming (step S61). When it is determined that the RB game is being played (YES), the RB game process (step S62) is performed, and then the flag-off process subroutine is terminated. Here, the RB game process is a process for a game using the RB lottery table (FIG. 16) until the number of winnings in the RB game or the number of RB games reaches a predetermined number. In this embodiment, since the probability of winning the general combination 2 is set to be very high as 1 / 1.03, the possibility of winning the general combination 2 is very high during the RB game. An advantageous game can be played.

  Next, when it is determined in step S61 that the gaming state is not RB gaming (NO), it is determined whether or not the gaming state is BB gaming (step S63). When it is determined that the BB game is being played (YES), the BB game process (step S64) is performed, and then the flag-off process subroutine is terminated. Here, the BB game process is a process for a game using the BB lottery table (FIG. 17) until the BB game end condition (maximum number of acquired game media) is reached. In this embodiment, since the probability of winning the RB role is set to a very high ¼, there is a very high possibility of winning the RB role that can be transferred to the RB game, and the RB role is won and won. By doing so, the player can play an advantageous game.

  Further, if it is determined in step S63 that the gaming state is not BB gaming (NO), it is determined whether or not there is a winning combination (step S65). When it is determined that there is a winning combination (YES), a winning combination process subroutine (step S66) described later is performed, and then the flag-off process subroutine ends.

  On the other hand, if it is determined in step S65 that there is no winning combination (NO), the flag-off process subroutine is terminated as it is.

<Explanation of the processing sub-routine at the time of winning>
The winning combination process will be described with reference to FIG. This winning combination process subroutine is a part of the control process of the flag-off process subroutine, and is executed only when the game is neither RB game nor BB game as shown in FIG.

  First, a winning symbol determination is made as to whether or not the reel symbol stopped by the reel fluctuation / stop subroutine is winning (step S71). Next, as a result of the winning symbol determination, it is determined whether or not the RB combination has been won (step S72).

  If it is determined that the RB combination has been won (YES), the RB flag is set to OFF to set the RB gaming state (step S73), and this subroutine is terminated. By setting the RB game state, the RB game is started from the next game, and it is determined that the RB game is in progress.

  If it is determined in step S72 that the RB combination has not been won (NO), it is determined whether or not the BB combination has been won (step S74). If the BB combination is won (YES), the BB combination flag is set to OFF and the BB gaming state is set (step S75). By setting the BB game state, the next game is determined to be a BB game.

  If it is determined in step S74 that the BB combination has not been won (NO), it is determined whether or not the general combination 1, the general combination 2 or the general combination 3 has been won (step S76). If any general combination such as general combination 1 is won (YES), the corresponding general combination flag is set to OFF (step S77), and this subroutine ends.

  If it is determined in step S76 that no general combination such as the general combination 1 has been won (NO), it is determined whether or not a re-game combination has been won (step S78). When it is determined that the re-game player has won (YES), the re-game flag is set to OFF and the re-game state is set (step S79). Then, this subroutine ends. By setting the replay state, the next game is determined to be a replay.

  If it is determined in step S78 that no re-game player has been won (NO), the winning combination processing subroutine is terminated.

<Description of main routine (continued)>
As described above, the flag-off process subroutine shown in FIGS. 9 and 10 ends. Here, returning to the main routine of FIG. 5, the winning determination and flag-off process subroutine in step S18 is terminated, the payout process in step S19 is terminated, and the main routine is terminated. Thereby, the control process for performing a game in which one process from when the symbol fluctuates until it stops is completed.

<Bet number production processing subroutine>
Next, the bet number effect processing subroutine will be described with reference to FIGS.

  As described above, in the combination lottery processing subroutine shown in FIG. 7, when the BB combination is won in the previous game (step S40), the BB flag is turned on (step S41). In order to perform the effect of notifying the winning of the BB role, it is determined whether or not the BB flag is turned on in the main routine shown in FIG. 5 (step S12), and it is determined that the BB flag is turned on (YES) ) Goes to the bet number effect processing subroutine (step S20) shown in FIGS.

  In FIG. 11, the bet number effect by this subroutine is not always executed when the BB combination is won in the previous game, but first, a lottery is performed to determine whether or not to execute the bet number effect (step S81). .

  If the result of the lottery is determined in step S82 and it is determined that the bet number effect is not executed (NO), the process proceeds to the bet number normal processing subroutine shown in FIG. 6 (step S83).

  On the other hand, if it is determined in step S82 that a bet number effect is to be executed (YES), it is determined whether or not a game medium has been inserted (step S84), as in the above-described bet number normal processing subroutine. If it is determined by this determination that a game medium has been inserted (YES), the process proceeds to the bet number normal processing subroutine shown in FIG. 6 (step S83), and the bet number is detected (see step S24 in FIG. 6). That is, in this embodiment, the bet number effect is performed only when the credited game medium is bet by the operation of each of the bet switches 32, 34, or 36.

  If it is determined in step S84 that no game medium is inserted (NO), the process proceeds to step S85 to determine whether there is a credited game medium. If there is a credited game medium (YES), it is determined whether a bet operation signal has been received (step S86). If a bet operation signal is received (YES), the number of bets is detected based on the bet operation signal (see step S87, step S93 in FIG. 12, and step S100 in FIG. 13).

  If there is no game medium credited in step S85 described above (NO), or if a bet operation signal is not received in step S86 (NO), the process returns to step S84 again, and steps S84 to S86 are performed. Repeat judgment.

  Next, in step S87, it is determined whether or not the detected number of bets is three. If it is determined that the detected number of bets is three (YES), the process proceeds to step S88, and the number of effect bets is set to two or one or lottery is performed. The result of the lottery is determined in step S89, and if it is determined that the number of effect bets is two as a result of the lottery (YES), this is stored in the RAM 110 as a new set bet number. Then, the number of effect bets is subtracted from the number of credits of the game medium (step S90). Thereafter, the bet number and credit number signals are transmitted to the sub-control circuit 200 (step S92). The control of the sub control circuit 200 that has received this signal will be described in detail later using the flowchart of FIG.

  If it is determined in step S89 that the number of effect bets is not two (1) as a result of the lottery (NO), this is stored in the RAM 110 as a new set bet number. Then, the number of effect bets is subtracted from the credit amount of the game medium (step S91). Thereafter, the bet number and credit number signals are transmitted to the sub-control circuit 200 (step S92).

  On the other hand, if it is determined in step S87 that the detected bet number is not three (NO), the process proceeds to step S93 in FIG. 12, and it is determined whether the detected bet number is two. If it is determined that the detected number of bets is two (YES), the process proceeds to step S94, and it is determined whether there are three or more credits. This is because at least three game media to be betted are required in order to perform an effect of setting the number of effect bets to three.

  If it is determined in step S94 that the number of credits is 3 or more (YES), the process proceeds to step S95, and the number of effect bets is 3 or 1 or lottery is performed. The result of the lottery is determined in step S96, and if it is determined that the number of effect bets is three as a result of the lottery (YES), this is stored in the RAM 110 as a new set bet number. Then, the number of effect bets is subtracted from the number of credits of the game medium (step S97). Thereafter, the bet number and credit number signals are transmitted to the sub-control circuit 200 (step S99).

  Further, when it is determined in step S94 that the number of credits is not three or more (NO), or when it is determined in step S96 that the number of effect bets is not three (one) as a result of the lottery. (NO) stores the effect bet number in the RAM 110 as one. Then, the number of effect bets is subtracted from the credit amount of the game medium (step S98). Thereafter, the bet number and credit number signals are transmitted to the sub-control circuit 200 (step S99).

  On the other hand, if it is determined in step S93 described above that the detected number of bets is not two (NO), the process proceeds to step S100 in FIG. 13 to determine that the detected number of bets is one. In step S101, it is determined whether there are three or more credits. This is because, in the same way as described above, in order to perform an effect in which the number of effect bets is set to three, at least three game media to be betted are required.

  If it is determined in step S101 that the total of the inserted number and the number of credits is 3 or more (YES), the process proceeds to step S102, and the effect bet number is set to 3 or 2 or a lottery is performed. The result of the lottery is determined in step S103, and when it is determined that the number of effect bets is three as a result of the lottery (YES), this is stored in the RAM 110 as a new set bet number. Then, the number of effect bets is subtracted from the number of credits of the game medium (step S104). Thereafter, the bet number and credit number signals are transmitted to the sub-control circuit 200 (step S108).

  If it is determined in step S103 that the number of effect bets is not three (two) as a result of the lottery (NO), this is stored in the RAM 110 as a new set bet number. Then, the number of effect bets is subtracted from the credit amount of the game medium (step S106). Thereafter, the bet number and credit number signals are transmitted to the sub-control circuit 200 (step S108).

  On the other hand, if it is determined in step S101 described above that the total number of inserted sheets and the number of credits is not three or more (NO), the process proceeds to step S105 to determine whether the number of credits is two or not. As a result, when it is determined that the number of credits is two (YES), the same processing as the above-described step S106 and step S108 is performed to set the number of effect bets to two.

  If it is determined in step S105 that the number of credits is not two (NO), only one of the detected bet numbers is set after all, and the production of the actual bet number effect is not performed. In this case, one detected bet number is stored as a new set bet number in the RAM 110, and one set bet number is subtracted from the credit amount of the game medium (step S107). Thereafter, the bet number and credit number signals are transmitted to the sub-control circuit 200 (step S108).

<Description of Sub Control Circuit Subroutine>
Next, the sub control circuit subroutine will be described with reference to FIG. FIG. 14 is a flowchart showing a sub-control circuit subroutine regarding the display of the bet number.

  The set bet number (including the effect bet number) transmitted in step S26 of the bet number normal process subroutine shown in FIG. 6 and steps S92, S99, and S108 of the bet number effect process subroutine shown in FIGS. When the signal is received by the sub control circuit 200, as shown in FIG. 14, it is first determined whether the set bet number is 1 to 3 (steps S110, S113, S116).

  If it is determined in step S110 that the set bet number is 1 (YES), the 1-bet number display lamp 51a shown in FIG. 1 is turned on (step S111), and the lamp of the active line display unit 24a is turned on. Is turned on (step S112), and the winning line L1 is validated.

  If it is determined in step S110 that the set bet number is not one (NO), the process proceeds to step S113 to determine whether the set bet number is two. When it is determined that the set bet number is 2 (YES), the 2-bet number display lamp 51b shown in FIG. 1 is turned on (step S114), and the lamps of the active line display units 24a, 24b and 24c are turned on. (Step S115), and the winning lines L1, L2A and L2B are validated.

  Further, if it is determined in step S113 that the set bet number is not two (NO), the process proceeds to step S116, and it is determined that the set bet number is three. Then, the 3-bet number display lamp 51c shown in FIG. 1 is turned on (step S117), and the lamps of the active line display sections 24a, 24b, 24c, 24d and 24e are turned on (step S118), and the winning lines L1, L2A are turned on. , L2B, L3A and L3B are enabled.

  According to the slot machine 10 according to the present embodiment, when the BB combination is won, a bet number different from the number assigned to the operated bet switch 32, 34 or 36 is set, and the different bet number is set. Accordingly, the player is elected to play the BB role by turning on the lamps of the bet number display lamps 51a, 51b or 51c and the active line display sections 24a, 24b, 24c, 24d and 24e. Can be notified (see FIGS. 11 to 14).

  By adopting such a notification means that imitates the malfunction, the player cannot be sure that the malfunction of the slot machine 10 or the notification that the BB role is won. It leads to a sense of expectation that you may have won.

  Further, in the slot machine 10 of the present embodiment, even when the BB role is won in the previous game, the fact that the BB role is won is not always notified (steps S81 to S81 in FIG. 11). (See S83), an uncertainty is added that there is a case where notification may not be made even if the BB combination is won. The player's sense of expectation can be increased by the uncertainty of the presence or absence of such notification.

  The slot machine of the present invention is not limited to the above-described embodiment. For example, in the above embodiment, the bet number effect is performed by lottery only when the BB combination is won, but the present invention is not limited to this. When the BB combination is not won in the previous game (see step S12 in FIG. 5), the bet control means 400 sets the bet number different from the bet number assigned to each bet switch 32, 34 or 36. Whether or not to perform may be selected by lottery. An example of this change is shown in FIG.

  FIG. 15 is a flowchart showing a modification of the bet number normal processing subroutine. In the modified example shown in the figure, processing (steps S201 to S203) for shifting to the bet number effect processing subroutine by lottery is added to the bet number normal processing subroutine shown in FIG. In FIG. 15, the same parts as those in FIG.

  If it is determined in step S12 of the main routine shown in FIG. 5 that the BB combination is not won (NO), the process proceeds to the bet number normal processing subroutine of FIG. In the figure, first, a lottery is performed to determine whether or not to execute the actual bet number effect (step S201). In the lottery of this step S201, the winning probability in the case of executing the actual bet number effect (YES) is set very low compared to the similar winning probability in the lottery of step S81 of the bet number effect processing subroutine shown in FIG. It is.

  The result of the lottery is determined in step S202, and if it is determined that the actual bet number effect is to be executed (YES), the process proceeds to the bet number effect processing subroutine shown in FIGS. On the other hand, if the bet number effect is not executed (NO), the same process as the bet number normal process subroutine shown in FIG. 6 is performed (S21 to S26).

  According to the slot machine 10 according to the modified example of the present embodiment, even when the BB role is not won in the previous game, the same bet number effect as when the BB role is won is performed. Uncertainty is added. As a result, even if the bet number effect is made, it is not always that the BB combination is won, and the player's expectation can be further increased when the bet number effect is made.

  In addition, the slot machine according to the present invention is not limited to the above-described embodiment, and various modifications can be made. For example, in the above-described embodiment, the bet number effect is performed only when a credited game medium is bet by operating the bet switches 32, 34, or 36 of 1 to 3, but the present invention is not limited thereto. Even when a game medium is inserted, a bet number different from the inserted number may be set.

  Further, not only the BB combination but also the RB combination is won, the bet number effect subroutine shown in FIGS. 11 to 13 may be executed. Further, in the above embodiment, the bet number display lamps 51a to 51c and the effective line display units 24a to 24e are employed as the bet number display means, but either one of them is omitted, a segment number display, a CRT or The number of bets may be displayed on a display device such as an LCD.
