Description

  The present invention relates to a gaming machine that is installed and used in a game hall such as a pachinko parlor.

  In the present specification, a pachislot machine is described as an example, so that medals are used as game media. However, game media include other media such as coins and pachinko balls. Further, “inserting medals (game media)” includes betting a credited medal with a bet button or the like in addition to actually inserting a medal into the medal slot. In addition, the internal winning is a state in which the winning combination is determined based on the lottery for determining the winning combination (hereinafter referred to as the winning winning lottery), and the symbols constituting the winning winning combination can be aligned on the winning line. A state in which the symbols constituting the winning combination that won an internal prize are aligned on the winning effective line is defined as a winning.

  Slot machines that are installed and used in amusement halls such as pachinko parlors are called pachislot machines, and medals that are used as gaming media are given a certain value, and medals earned by playing games are various prizes. Can be replaced. For this reason, one of the purposes is that the player wins a large number of medals, and a game is selected by selecting a stand that is easy to obtain the right to shift to the special mode, which is advantageous in acquiring game media than the normal mode. It is common to try to do this. Such a game mode includes, for example, a big bonus (hereinafter referred to as BB) mode and a regular bonus (RB) mode. In particular, the BB mode is shifted to the RB mode a predetermined number of times, and before being shifted to the RB mode, Since the transition to the RB introduction mode in which the winning probability of the winning combination that is accompanied by the payout of medals is increased, a large amount of medals can be obtained in a short period of time. Thus, raising expectations for winning a large number of medals in a short period is one of the important factors in attracting players to slot machines.

  However, having the possibility of winning a large number of medals in a short period of time as described above makes the player have great interests, but on the other hand, it makes the player's gambling mischief mischievous. It may also damage the health of the. For this reason, the player sets an upper limit on the number of medals that can be acquired in a single transition to a special mode, such as the BB mode or the RB mode, which is advantageous for acquiring medals over the normal mode. It is considered that the special mode is terminated when the number of acquired medals reaches the upper limit. (For example, see Patent Document 1)

JP 2003-199881 A

  However, if there is an upper limit on the number of medals that can be acquired in the special mode, the special mode may end because the number of medals acquired by the player reaches the upper limit while the medals are being paid out. . If the special mode ends before the medal payout is completed and an unpaid medal is generated, the player may be dissatisfied with the game and lose interest in the slot machine.

  The present invention has been made to solve the above-described problems, and when an upper limit is set on the number of game media that can be acquired in a special mode that is advantageous in acquiring game media such as medals over the normal mode. Even if unpaid medals are generated due to reaching the upper limit, or even if there is no shortage of acquired game media when the special mode ends before reaching the upper limit, An object of the present invention is to provide a gaming machine, a program, and a recording medium that prevent the dissatisfaction from being raised and can reach the upper limit according to the skill.

  The gaming machine of the present invention includes a reel in which a plurality of types of symbols are arranged and rotates in response to a game start operation, and a winning combination determining means for determining either a lose or a plurality of types of winning combinations by lottery. In the gaming machine in which the plurality of types of winning combinations include a small role with payout of game media and a plurality of types of small roles are set so that the number of payout of game media is different from each other, the normal mode and the normal mode The special mode that is more advantageous for acquiring game media than the game mode is set, and the number of game media acquired by the player in the special mode game is the predetermined number set in advance and the number of game media paid out is the largest. Special mode ending means for ending the special mode when the number is equal to or more than the number of differences from the number of game media to be paid out when the small role is won, and the winning combination In the game during the predetermined period of the normal mode that is transferred after the special mode is completed, and a plurality of types of winning combination lottery tables that are used in the lottery with the fixed means and have different winning probabilities for the small roles, the normal mode Table selection means for causing the winning combination determining means to perform lottery using the winning combination lottery table having a winning probability of a small combination higher than a game outside a predetermined period is provided. Note that the number of game media acquired by the player includes a difference between the number of inserted medals and the number of acquired medals, that is, a so-called net increase. Moreover, it is preferable that the special mode is set to a state in which a transition can be made when a predetermined winning combination is determined by lottery by the winning combination determining means.

  The predetermined period is preferably terminated when the winning combination is determined by the winning combination determining means. In this case, it includes the case where the player wins the winning combination as the opportunity.

  In addition, an acquisition number calculation means for calculating the number of game media acquired by the player during the predetermined period is provided, and the number of game media calculated by the acquisition number calculation means is the small role with the largest number of game media payouts. It is preferable that the predetermined period ends when the number of game media to be paid out at the time of winning is exceeded.

  The predetermined period is preferably a period until the number of games played reaches a predetermined number.

  Further, an acquisition number calculating means for calculating the number of game media acquired by the player during the predetermined period is provided, and the number of games played during the predetermined period and the game medium acquired by the player during the predetermined period The table selection means preferably selects the winning combination lottery table according to the number of the winning combinations.

  Note that the program of the present invention is a player in a special mode game that is advantageous in obtaining game media than in the normal mode, and a winning combination determining means for determining either a loser or a plurality of types of winning combinations by lottery. The number of game media acquired by the player is equal to or greater than the number of differences between the predetermined number set in advance and the number of game media paid out when the small role with the largest number of game media paid out wins, and is less than the predetermined number. The special mode ending means for ending the special mode in the case of a game, and the game during the predetermined period of the normal mode transferred after the special mode is ended, are smaller than the game other than the predetermined period of the normal mode. It is for causing a computer of a gaming machine to function as a table selection means for causing the winning combination determination means to perform a lottery using the winning combination lottery table with a high winning probability. .

  In addition, the recording medium of the present invention has a winning combination determining means for determining any one of the winning combination and a plurality of types of winning combinations by lottery, and a special mode game that is advantageous in obtaining a game medium than the normal mode. The number of game media acquired by the player is equal to or greater than the number of differences between a predetermined number set in advance and the number of game media paid out when a small role with the largest number of game media paid out wins, and less than the predetermined number Special mode ending means for ending the special mode in the case of the game, and in the game during the predetermined period of the normal mode transferred after the special mode ends, the small role than the game outside the predetermined period of the normal mode Program for causing a computer of a gaming machine to function as table selection means for causing the winning combination determination means to perform lottery using the winning combination lottery table with a high winning probability It is recorded as computer-read, possible.

  It is preferable to provide a table lottery means for determining the type of the winning combination lottery table used in the predetermined period by lottery. In this case, since it becomes impossible to predict which of the multiple types of small roles will be won, the player's expectation to win a small role with a large number of game media payouts is increased. Can give a sense of tension to the game.

  Moreover, it is preferable to change the length of the predetermined period according to the number of the differences at the end of the special mode. In this case, it is possible to give the player a sense of expectation that the length of the predetermined period will be long, and to increase the interest in the game.

  In addition, it is preferable that the winning combination lottery table is selected so that the winning probability of a specific small combination out of a plurality of types of small combinations is increased according to the number of differences at the end of the special mode. In this case, it becomes possible to increase the winning probability of a small role accompanied by paying out medals equal to or substantially equal to the number of the differences, and the payout rate of the gaming machine varies extremely. Can be prevented.

  The gaming machine according to the present invention is a game medium to be paid out when a small role winning the number of game media acquired by a player in a special mode game and having the largest number of game media paid out is won. In the game during the predetermined period of the normal mode which is shifted after the special mode is ended when the special mode is ended when the difference is not less than the predetermined number and not more than the predetermined number, the predetermined period of the normal mode The winning lottery table, which has a higher chance of winning a small role than other games, is used for lottery, so the number of game media that the player can acquire in the special mode is prevented from exceeding the predetermined number. Furthermore, it becomes possible for the player to acquire a number of game media substantially equal to the upper limit. As a result, when an upper limit is set for the number of game media that can be acquired in the special mode, which is advantageous for acquiring game media such as medals over the normal mode, an unpaid medal is generated because the upper limit is reached. Or, even if the lack of the number of game media acquired when the special mode is terminated before the upper limit is reached, it is possible to prevent the player from being dissatisfied with the game, and the upper limit depending on the skill. Can be reached.

  In addition, since the predetermined period ends when the winning combination is determined by the winning combination determining means, it is possible to reliably give the player an opportunity to acquire the winning combination. In addition, if the winning combination is elected, if the small role is not won, the player loses the number of game media obtained, and if the winning combination wins, If you do not win a small role until you win a winning combination with more payouts, you will be able to increase the number of game media acquired, so highly skilled experts who win the winning role will have an advantage over beginners Become. For this reason, a player's skill can be reflected in a game.

  In addition, an acquisition number calculation means for calculating the number of game media acquired by the player during the predetermined period is provided, and the number of game media calculated by the acquisition number calculation means is the small role with the largest number of game media payouts. The predetermined period ends when the number of game media to be paid out at the time of winning is exceeded, so if the total number of game media acquired in the special mode and the predetermined period is added up, the game acquired by the player Since the number of media is equal to or greater than the above upper limit, it is possible to prevent the player from being dissatisfied with the game. In this case, when the number of game media acquired by the player is calculated as a net increase, the length of the predetermined period can be adjusted according to the skill of the player.

  Further, since the predetermined period is a period until the number of games played reaches a predetermined number, a skilled person who wins a winning combination can acquire more game media than a beginner. The difference in the skill of the player can be reflected in the game.

  Further, an acquisition number calculating means for calculating the number of game media acquired by the player during the predetermined period is provided, and the number of games played during the predetermined period and the game medium acquired by the player during the predetermined period The table selection means selects the winning combination lottery table in accordance with the number of games, so that, for example, when the number of game media acquired by the player just before the end of the predetermined period, The player wins in a predetermined period, such as increasing the winning probability of a role and increasing the winning probability of a small role with a small number of payouts when the player has a large number of game media just before the end of the predetermined period. The number of possible game media can be adjusted.

  FIG. 1 shows an appearance of the slot machine 10, and first, an outline of a game flow of the slot machine 10 will be described. As shown in FIG. 1, the slot machine 10 is provided with a normal mode and a BB mode (special mode). BB wins an internal prize when BB is won in the winning combination lottery in the game in the normal mode, and shifts to the BB mode when BB wins. In the BB mode, the number of medals acquired by the player (the difference between the number of inserted medals and the number of acquired medals) is a predetermined number (for example, 480) set in advance and the number of medals paid out is the largest. The process ends when the number of medals to be paid out when the winning combination wins is equal to or more than the number of medals (for example, 10) and is equal to or less than 480. It is preferable that the number of medals to be paid out when the small role having the largest number and the number of medals to be paid out wins an appropriate number.

  The slot machine 10 is provided with a housing 10 a including a storage box 11 and a front door 12. Three display windows 13 are provided on the front door 12, and a first reel 14 a, a second reel 14 b, and a third reel 14 c are rotatably incorporated in the back of each display window 13. As is well known, a plurality of types of symbols are arranged at a constant pitch on the outer periphery of the first to third reels 14a to 14c, and three symbols per reel can be observed through the display window 13 when the reels are stopped. Become. As a result, a total of five straight winning winning lines in which the symbols of the reels are combined one by one and three in the horizontal direction are set.

  Prior to the start of the game, when one medal is inserted from the medal insertion slot 16, the winning line in the center horizontal is activated. The book winning line is activated. Further, it is possible to credit (store) up to 50 medals, and the number of credited medals is displayed on the credit number display unit 17. For example, 4 symbols per reel can be observed from the display window 13, and in addition to the horizontal 4 winning lines, another prize that is folded to combine one symbol for each reel. It is also possible to set an effective line.

  When the start lever 18 is operated, the first to third reels 14a to 14c are rotated all at once. By operating these stop buttons 19a to 19c, the first to third reels 14a to 14c corresponding to the buttons are individually stopped. Various operation buttons such as a bet button and a payout button are provided on the operation panel above the stop buttons 19a to 19c. Since the functions of these operation buttons are well known, the details thereof are omitted.

  A medal tray 20 is provided at the lower part of the housing 11, and a payout medal obtained when a prize is obtained in the game is paid out to the medal tray 20 from the payout opening 21.

  As shown in FIG. 2, the operation of the slot machine 10 is basically controlled by a control unit 30 including a CPU (special mode ending means and table selection means) 30 a and a memory 31. In addition to the CPU 30a and the memory 31, the control unit 30 is provided with an electronic lottery unit 39, a winning combination determining unit 40, a net increase number calculating unit 41, and a BB end determining unit 42 which will be described later.

  The medal sensor 32 detects an appropriate medal inserted from the medal slot 16 and inputs it to the CPU 30a. A selector is incorporated in the back of the medal slot 16 and an inappropriate medal is discharged to the medal tray 20. In addition, when a medal is inserted at an inappropriate timing, for example, a medal that is inserted in the middle of a game or while various operation buttons are pressed is not passed through the medal sensor 32. The medal tray 20 is discharged.

  Since the number of medals to be inserted prior to the start of the game is limited to 1 to 3, the medal sensor 32 also detects medals inserted after the fourth one when the credit function is not used. Without being discharged to the medal tray 20. The credit function is turned on / off every time the payout button is pushed. When the credit function is on, medals inserted after the fourth sheet are also detected by the medal sensor 32 and credited into the slot machine up to 50 sheets. The number of credited medals is digitally displayed on the credit number display unit 17. When the credit function is used, a medal insertion operation is performed by the operation of the 1 bet button or the MAX bet button described above, and the bet number is sequentially subtracted from the credit number. Further, when a game is performed and a winning combination with a medal payout is won, a payout medal is also credited, and a credited medal is paid out to the medal tray 20 when a payout button is operated.

  The CPU 30a counts the number of 1 to 3 medals inserted prior to the start of the game based on the detection signal from the medal sensor 32, and thereby determines the number of valid activated pay lines. The number of credits is counted by another credit medal counter (not shown).

  The start signal sensor 33 inputs a game start signal to the CPU 30a when the start lever 18 is operated after 1 to 3 medals are inserted. In response to the game start signal, the CPU 30a rotates the first to third reels 14a to 14c based on the game execution program stored in the ROM area of the memory 31 and starts the game process. In addition to the normal mode, the game execution program includes a program that shifts to the BB mode and executes game processing.

  The drive and stop control of the first to third reels 14a to 14c are performed by the CPU 30a and the reel drive controller 34. The first to third reels 14a to 14c are respectively fixed to the drive shafts of the individual stepping motors 35a to 35c, and each reel is controlled by controlling the driving of the stepping motors 35a to 35c. Note that the RAM area of the memory 31 is a working area, and is used for temporary storage or rewriting of flags and data used for each game.

  Since the stepping motors 35a to 35c rotate at a rotation angle corresponding to the number of supplied drive pulses, the CPU 30a controls the rotation angle of the first to third reels 14a to 14c by controlling the number of drive pulses supplied. The stop position of the reel can be determined by stopping the supply of the drive pulse. In each reel, reflection signal portions 36a to 36c are integrally formed at the reference position, and the photosensors 37a to 37c photoelectrically detect the passage of each reflection signal portion for each rotation. Detection signals from the photosensors 37a to 37c are input to the CPU 30a as a reset signal for each reel.

  The CPU 30a is provided with a pulse counter for each of the stepping motors 35a to 35c, and counts the number of drive pulses supplied to each of the stepping motors 35a to 35c. When the reset signal is input from the photosensors 37a to 37c, the count value of the corresponding pulse counter is cleared. Therefore, the number of drive pulses corresponding to the rotation angle within one rotation of each reel is stored in each pulse counter while being sequentially updated.

  A symbol table is stored in the ROM area of the memory 31, and the symbol table represents the number of drive pulses corresponding to the rotation angle from the reference position of each reel and the symbols arranged on the reel at a constant pitch. A code is associated. Therefore, by monitoring the count value of the pulse counter for each reel, for example, it is possible to identify which symbol has moved on the center winning effective line, and how much more the reel should be rotated. It is possible to predict whether the target symbol will move on the winning line.

  The stop button sensors 38a to 38c input a stop signal for each reel to the CPU 30a when the stop buttons 19a to 19c are operated. The start lever 18 is operated to start the rotation of all reels. When these rotations reach a steady speed, the operation of the stop buttons 19a to 19c is validated. Thereafter, by operating these, stop control of the corresponding first to third reels 14a to 14c is started.

  The outer peripheral surfaces of the first to third reels 14a to 14c are partitioned into a predetermined number of frames for each predetermined range, and one symbol is assigned to each frame. The stop control of the first to third reels 14a to 14c is performed within a range of five symbols (retraction range). For example, when the stop buttons 19a to 19c are operated, the control is performed on the winning line. If the symbols that make up the winning combination determined in the winning combination lottery are included in the four consecutive symbols from the symbol being played, the first to third reels 14a to 14c are stopped. The stop control of the first to third reels 14a to 14c is performed so that the time is delayed and the symbols constituting the winning combination are stopped on the winning winning line (hereinafter referred to as pull-in control).

  Further, when the stop buttons 19a to 19c are operated so that a winning combination not determined by the winning combination determining unit 40 is won, the first to third reels 14a to 14c are stopped so that the winning combination is not won. Control is performed (hereinafter referred to as kick control).

  When a plurality of stop buttons are operated almost simultaneously, only the reel corresponding to the stop button with the earlier operation timing stops, and when fully operated simultaneously, none of the reels stop. In addition, the reel stop control is not limited to the symbols that make up the winning combination, so-called reach that informs the player of the winning combination that is winning internally by the type or combination of symbols stopped on the winning line. You may make it display eyes.

  The electronic lottery unit 39 and the winning combination determining unit 40 constitute a winning combination determining means. The CPU 30a operates the electronic lottery unit 39 in response to the game start signal. The electronic lottery unit 39 includes a random number generator and a random number sampling circuit, and draws one random value every time a game is started. The random value selected by lottery is input to the winning combination determining unit 40. The winning combination determination unit 40 determines what type of winning combination is awarded in the currently executed game according to the input value.

  The winning combination determination unit 40 is provided with a plurality of winning combination lottery tables in which all random numbers generated by the random number generator of the electronic lottery unit 39 are grouped into a plurality of numerical ranges, and the winning combination is assigned to each group. It has been. In the winning combination lottery table, the first winning combination lottery table 40a and the second winning combination lottery table 40b used in the normal mode, the winning combination lottery table used in the BB mode, and the winning combination lottery used in a state where the BB has won an internal prize. There are tables.

  The groups of the first winning combination lottery table 40a and the second winning combination lottery table 40b include a BB that gives the right to shift to the BB mode, a small role that involves paying out a predetermined number of medals, and the same bet number without inserting medals. The winning role, such as replay that gives the right to play the next game, and the loss that does not cause any hits are assigned. The type of winning combination to be won is determined depending on which group the sampled random number value belongs to. There are a plurality of small roles, and a payout medal is assigned to each. In the second winning combination lottery table 41b, random value grouping is performed so that the numerical range of the group to which the small combination is assigned is larger than that of the first winning combination lottery table 41a. For this reason, when the lottery is performed using the second winning combination lottery table 42b, the winning probability of the small combination is higher than when the lottery is performed using the first winning combination lottery table 42a.

  The net increase number calculation unit 41 is the number of medals that the player acquires in the game when the operation of the stop buttons 19a to 19c is performed so that the winning combination with the payout of medals is won in the BB mode game. Is calculated. The CPU 30 a counts the number of medals inserted from the medal slot 16 based on the detection signal from the medal sensor 32 in the BB mode game, and inputs the counted number of medals to the net increase calculation unit 41. Further, in the game of the BB mode, when the stop buttons 19a to 19c are operated so that the winning combination with payout of medals wins, the CPU 30a determines the number of payout medals for each type of winning combination. With reference to the table, the number of medals to be paid out is input to the net increase number calculation unit 41. The payout table is stored in the ROM area of the memory 31. The net increase number calculation unit 41 calculates the number of difference between the number of inserted medals and the number of medals to be paid out, and inputs the calculated number to the CPU 30a. The CPU 30 a writes the number of medals calculated by the net increase number calculation unit 41 while accumulating in the RAM area of the memory 31. That is, in the BB mode, the number of medals acquired by the player in the BB mode is written in the RAM area of the memory 31.

  The BB end determination unit 42 determines whether or not the number of medals acquired by the player in the BB mode is 470 or more and 480 or less. The CPU 30a refers to the number of medals acquired by the player from the RAM area of the memory 31 every time a game in the BB mode is performed, and inputs it to the BB end determination unit 42. The BB end determination unit 42 determines whether the number of sheets input from the CPU 30a is 470 or more and 480 or less, and inputs the determination result to the CPU 30a.

  The hopper device 43 pays out a prescribed number of payout medals to the medal tray 20 according to the type of winning combination, or adds the prescribed number to the credit counter. The CPU 30a controls the driving of the hopper device 43 with reference to the payout table in the memory 31.

  Next, the operation of the slot machine configured as described above will be described. As shown in FIG. 3, in the slot machine 10, a game in the normal mode is first performed. When 1 to 3 medals are inserted, the number of inserted medals is counted by the CPU 30a. When the start lever 18 is operated, a game start signal is input from the start signal sensor 33 to the CPU 30a, and rotation of the first to third reels 14a to 14c is started.

  When the start lever 18 is operated, the electronic lottery unit 39 samples the random number value and compares the sampled random number value with the first winning combination lottery table 40 a of the winning combination determining unit 40. Thereby, the winning combination lottery is performed, and the type of the lost or winning combination is determined. When the winning combination lottery is completed, a winning combination determination signal is fed back to the CPU 30a. In response to this, the CPU 30a validates the operation of the stop buttons 19a to 19c. The CPU 30a monitors the operation timing of the stop buttons 19a to 19c while referring to the count value of the aforementioned pulse counter provided for each reel, and the winning design determined by the winning combination determining unit 40 is stopped on the winning effective line. Stop control of the 1st-3rd reels 14a-14c is performed so that it may be easy.

  When BB is determined by the winning combination determining unit 40, the CPU 30a and the reel drive controller 34 allow the first to third reels 14a so that BB can be won when the stop buttons 19a to 19c are operated. The BB has won an internal prize by performing stop control of .about.14c.

  When the player wins BB, the CPU 30a first reads the execution program for the RB introduction mode from the ROM area of the memory 31, and shifts from the normal mode to the RB introduction mode. In the RB introduction mode, a game is played with 1 to 3 medal bets, and replay is performed in the RB introduction mode (in the slot machine of this embodiment, replay is substituted as a winning combination for shifting to the RB mode). When winning and winning, the RB introduction mode is switched to the RB mode. The RB mode ends when a predetermined winning combination is won 8 times or 12 games are played. Thereafter, in the BB mode, the game in the RB introduction mode and the RB mode is repeated.

  In the game in the BB mode, the CPU 30 a accumulates and writes the number of medals calculated by the net increase number calculation unit 41 in the RAM area of the memory 31. Then, the number of sheets written in the memory 31 is referred to and input to the BB end determination unit 42. The BB end determination unit 42 determines whether the number of sheets input from the CPU 30a is 470 or more and 480 or less, and inputs the determination result to the CPU 30a.

  If the BB end determination unit 42 does not determine that the number of medals acquired by the player is 470 or more and 480 or less, the CPU 30a continues to execute the game in the BB mode. If the BB end determination unit 42 determines that the number of medals acquired by the player is 470 or more and 480 or less, the CPU 30a ends the BB mode and shifts to the normal mode.

  In the game in the normal mode after the end of the BB mode, the CPU 30a inputs a signal for performing lottery using the second winning combination lottery table 42b to the electronic lottery unit 39 until the first winning of a small combination occurs, and the electronic lottery The part 39 is caused to perform the winning combination lottery using the second winning combination lottery table 42b. If the winning combination lottery is performed using the second winning combination lottery table 42b, the winning probability of the small combination is higher than the case where the winning combination lottery is performed using the first winning combination lottery table 41a. The period (predetermined period) until the winning of the first small role in the normal mode that has been shifted to after completion is higher than the other periods. The “small role normal probability” in the figure indicates a state in which a lottery is performed using the first winning combination lottery table 40a, and the “small role high probability” uses the second winning combination lottery table 40b. The state where the lottery is performed.

  As described above, while the number of medals that can be acquired in the BB mode in the normal mode after the end of the BB mode is surely suppressed to 480 or less, the occurrence of unpaid medals can be prevented. Even if the number of acquired medals does not reach 480, the winning probability of the small role is increased until the small role is won in the game in the normal mode, so that it is possible to prevent the player from being dissatisfied with the game.

  In the present embodiment, it is preferable to reflect the difference in the skill of the player in the game. In this case, a notification means for notifying that the small role has been won is provided, and the small role symbols constituting the small role are different between the small role symbols, or different types of small role symbols or other winning roles. It is good to arrange so that five or more symbols which comprise may be arrange | positioned.

  As a result, when the selected small role symbol is positioned within the pull-in range while observing the first to third reels 14a to 14c rotating at the timing, the stop buttons 19a to 19c are operated. Otherwise, the player cannot be drawn onto the winning effective line, so that the player's skill at the time of operating the stop buttons 19a to 19c when the small role is won internally can be reflected in the game. In this case, the player has a small role with a small number of payouts (for example, when the small role is set to two types, ie, a five-valued role in which five medals are paid out and a ten-timed character in which ten medals are paid out) ) Is won, if the stop buttons 19a to 19c are operated so that the five-piece combination does not win, that is, the five-piece combination symbol constituting the five-piece combination is out of the drawing range, In this case, when the winning combination is 10 and a prize is won, the number of medals can be increased. For this reason, a skilled worker who has a high skill to stop the reel at a desired position while observing the rotating reel is more advantageous than a beginner, and can increase the interest of the skilled player in the game. Can be urged.

  FIG. 4 shows an example in which a recording medium (CD, flexible disk, IC memory, MO, etc.) 60 is installed in the slot machine 10, and the means shown in the flowchart of FIG. The program for implement | achieving by the computer 61 containing 31 is stored. In this case, for example, a winning combination deciding means for determining one of a winning combination and a plurality of types of winning combinations by lottery, and a game acquired by the player in a special mode game that is advantageous for acquiring a game medium than the normal mode. When the number of media is equal to or greater than the number of differences between a predetermined number set in advance and the number of game media to be paid out when the winning combination with the largest number of paid out game media is won, and less than the predetermined number The special mode ending means for ending the special mode and the game during the predetermined period of the normal mode transferred after the special mode is ended have a higher probability of winning the small role than the game outside the predetermined period of the normal mode. A recording medium 60 stores a program for causing the computer 61 to function as table selection means for causing the winning combination determination means to perform lottery using the winning combination lottery table. Record. Then, the recording medium 60 is loaded into the reading device 62 and the program is installed in the slot machine 10.

  The program can be distributed to the slot machine 10 using the Internet instead of being installed via the recording medium 60. It is also possible to install the distributed program of the present invention or the program of the present invention read from the recording medium 60 in a personal computer and play a slot machine game on a monitor.

  In the above embodiment, the predetermined period during which the winning combination of the small role is increased until the first small role winning in the normal mode after the end of the BB mode is set. However, for example, a predetermined number of games are performed during the predetermined period. Will end when a small role is won a predetermined number of times, will end when a small role is won a predetermined number of times, or a small role with the largest number of medals won by a player during a predetermined period will win The end condition may be set as appropriate, for example, the process ends when the number of medals to be paid out is equal to or more, or is determined according to the difference between the number of medals acquired by the player in the BB mode and 480.

  When the predetermined period ends when the number of medals acquired by the player during the predetermined period exceeds the number of medals to be paid out when the winning combination with the largest payout number wins, for example, as shown in FIG. As described above, when the BB end determination unit 42 determines that the number of medals acquired by the player is 470 or more and 480 or less, the CPU 30a ends the BB mode and shifts to the normal mode. For example, in a game in a predetermined period in the normal mode, when the stop buttons 19a to 19c are operated so that a small role wins, the CPU 30a operates the net increase number calculation unit (acquired number calculation means) 41. Then, the number of medals acquired by the player in the game is calculated. Thereafter, the CPU 30 a accumulates and writes the number of medals calculated by the net increase number calculation unit 41 in the RAM area of the memory 31. Then, the CPU 30a determines whether or not the number of medals acquired by the player in the game for a predetermined period is equal to or more than the number of medals to be paid out when the small role with the largest payout number wins. When it is determined that the number of medals earned by a player in a game for a predetermined period is equal to or more than the number of medals to be paid out when the small combination with the largest number of payouts wins (for example, 15 The CPU 30a switches the winning combination lottery table and wins the winning combination lottery, for example, when two types of 8 winning combinations are set, and a game is played with all 3 medals inserted and the 8 winning combination is won for the third time) The winning combination lottery is performed using the table 40a, and the small combination is set to the normal winning probability. Thereby, the game of a predetermined period is complete | finished.

  When the predetermined period is ended when a predetermined number of games are performed, for example, as shown in FIG. 6, the number of medals acquired by the player at the BB end determination unit 42 is 470 or more and 480 or less. If it is determined that it has been, the CPU 30a ends the BB mode and shifts to the normal mode. For example, in a game for a predetermined period, the CPU 30a accumulates and writes the number of times the game has been performed in the RAM area of the memory 31 every time the game is performed. When the number of games written in the memory 31 reaches a preset number of games, the CPU 30a switches the winning combination lottery table and performs the winning combination lottery using the winning combination lottery table 40a. And make the small role a normal winning probability. As a result, the predetermined period ends. Note that the number of games that can be played until the predetermined period ends may be determined by lottery.

  When the predetermined period is determined according to the difference between the number of medals acquired by the player in the BB mode and the number of 480, for example, as shown in FIG. When it is determined that the number is 470 or more and 480 or less, the CPU 30a calculates a difference number M between the number of medals acquired by the player in the BB mode and 480. Thereafter, the CPU 30a ends the BB mode and shifts to the normal mode. For example, in the case of 0 ≦ M ≦ 5, the CPU 30a performs the winning combination lottery using the second winning combination lottery table 40b until the game is performed 10 times, and in the case of 5 ≦ M, the game is 5 The winning combination lottery is performed using the second winning combination lottery table 40b until it is performed twice. After the respective number of games have been performed, the CPU 30a switches the winning combination lottery table to perform the winning combination lottery using the winning combination lottery table 40a, and sets the small combination to the normal winning probability.

  As described above, when the difference number M calculated by the CPU 30a is large, the period in which the winning combination of the small role is increased is lengthened, and when the difference number M is small, the period in which the winning role of the small role is increased is shortened. Although it is preferable, the period during which the winning probability of the small combination is high may be set as appropriate. In addition, the period during which the winning probability of the small role is high may be set in consideration of the winning probability of the small role, for example, until 10 games are played when the winning probability of the 10-piece role is 1/10. preferable.

  In the above embodiment, the winning probabilities of all of the plurality of small roles are increased until the first small role winning is generated during the predetermined period of the normal mode after the end of the BB mode. You may make it the winning probability of the specific small combination of a combination increase. In addition, the winning probability of the small role may be selected according to the number of games played during the predetermined period and the number of medals acquired by the player during the predetermined period.

  When the winning probability of a specific small role among a plurality of types of small roles is increased, for example, as shown in FIG. 8, the number of medals acquired by the player in the BB end determination unit 42 is 470 or more and 480. When it is determined that the number is less than or equal to the number, the CPU 30a calculates a difference number M between the number of medals acquired by the player in the BB mode and 480. Thereafter, the CPU 30a ends the BB mode and shifts to the normal mode. The CPU 30a sets three kinds of small roles with a payout number of M or less (for example, three types of small roles, such as five, eight, and fifteen), and when the difference number M is 10, The winning combination lottery table that increases the winning probability of the winning combination is selected and the winning combination lottery is performed. Then, when the number of medals acquired by the player after the BB mode is over the difference number M or more, the CPU 30a switches the winning combination lottery table and performs the winning combination lottery table 40a. And make the small role a normal winning probability.

  FIG. 9 shows an example in which the winning probability of a small role is selected according to the number of games played during the predetermined period and the number of medals acquired by the player during the predetermined period. As described above, when the BB end determination unit 42 determines that the number of medals acquired by the player is 470 or more and 480 or less, the CPU 30a ends the BB mode and shifts to the normal mode. In a game during a predetermined period in the normal mode, the CPU 30a wins a winning combination with a high winning probability of a small role with a small number of payouts (for example, when 5 types of small roles are set and 5 types are played) The lottery table is selected and the winning combination lottery is performed. In addition, the CPU 30a accumulates and writes the number of times the game has been performed in the RAM area of the memory 31 every time the game is performed in the game for a predetermined period. Further, when the small combination is won and the stop buttons 19a to 19c are operated so that the small combination wins, the CPU 30a operates the net increase number calculating section 41, and the medal that the player acquires by the game The number of sheets is calculated. Thereafter, the CPU 30 a accumulates and writes the number of medals calculated by the net increase number calculation unit 41 in the RAM area of the memory 31. Then, the CPU 30a refers to the number of times that the game has been played from the memory 31 and the number of medals acquired by the player, for example, the number of medals that the player has acquired when the number of times that the game has been reached reaches ten times. It is determined whether or not is less than 20 sheets. In this determination, when the number of medals acquired by the player is 20 or less, the CPU 30a wins the winning combination lottery table in which the winning probability of the 15-sheet combination in which the number of medals to be paid out is larger than the 5-piece combination. Select to make a winning draw. When the number of games written in the memory 31 reaches a preset number of games, the CPU 30a switches the winning combination lottery table and performs the winning combination lottery using the winning combination lottery table 40a. And make the small role a normal winning probability. In this example, it is assumed that the period until the winning combination lottery table is switched, that is, the number of games that can be played before the end of the predetermined period exceeds 10.

  In the above embodiment, the winning combination lottery table 40b is used to perform the winning combination lottery table in the normal mode after the end of the BB mode, but the winning combination lottery table used in the normal mode after the end of the BB mode is determined by lottery. It's okay. An example in this case will be described with reference to FIG. 10, but the same reference numerals are used for portions having functions similar to those of the above-described embodiment, and description thereof is omitted.

  For example, as shown in FIG. 10, the winning combination determination unit 40 has a winning combination lottery table 40c having a higher winning probability of 10 winning combinations than the winning combination determining table 40a, and a winning probability of 5 winning combinations than the winning combination determining table 40a. A high winning combination lottery table 40d is provided. Further, a table lottery unit (table lottery means) 70 is provided in the control unit 30. The table lottery unit 70 determines by lottery which of the winning combination lottery table 40c and the winning combination lottery table 40d is to be performed in the normal mode after the end of the BB mode. The result of the lottery is input to the CPU 30a.

  As shown in FIG. 11, when the BB end determination unit 42 determines that the number of medals acquired by the player is 470 or more and 480 or less, the CPU 30a operates the table lottery unit 70 to win the winning combination. It is determined by lottery which of the lottery table 40c and the winning combination lottery table 40d is used to perform the winning combination lottery. Thereafter, the CPU 30a ends the BB mode and shifts to the normal mode. Then, the CPU 30a causes the winning combination lottery using either the winning combination lottery table 40c or the winning combination lottery table 40d in accordance with the lottery result in the table lottery unit 70. As a result, in the normal mode after the end of the BB mode, the winning probability of either the five-piece combination or the ten-piece combination increases. When the winning combination of 5 or 10 wins, the CPU 30a causes the winning combination lottery table 40a to be selected.

  In the above embodiment, the BB mode is set as the special mode. However, the special mode is, for example, the RB mode, when the reel stop operation is performed, the symbols positioned on the winning line are stopped, and the predetermined winning combination It is more advantageous to acquire game media than the normal mode, such as challenge time (CT) mode that controls the stop of the reel so that the player can not win, and the number of game media acquired by the player reaches the predetermined number In such a case, the content may be appropriately changed.

  The present invention can be applied not only to a reel drive type slot machine but also to a slot machine using a liquid crystal panel, a pachinko machine, a game machine, and the like.
