[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a gaming machine that is installed and used in a game hall such as a pachinko parlor.
[0002]
[Prior art]
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. Furthermore, a state where the winning pattern is aligned on the winning line is a winning state, and a state where a winning combination is drawn by electronic lottery in a state before winning is determined as an internal winning.
[0003]
Slot machines that are installed and used in amusement halls such as pachinko parlors are called pachislot machines, and given a certain value to the medal that is the game medium, various medals earned by playing games Can be replaced. For this reason, the player generally aims to acquire a large number of medals, and generally selects a table that is easy to obtain the right to shift to the bonus game mode and plays a game. The bonus 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 the transition to the RB mode, Since the transition to the RB introduction mode in which the winning probability is high, a large amount of medals can be obtained in a short period of time.
[0004]
Providing the expectation that a large number of medals can be obtained in a short period is an important factor in attracting players to the slot machine. In addition to the bonus game mode, a special mode that can expect a large number of medals is provided. There is a tendency to provide a large number of models that have been devised in various ways in order to enlighten the players. As one of the special modes, there is known an assist time (AT) mode in which a reel stop operation mode is informed so as to increase a player's profit acquisition probability. In the AT mode, for example, the player is notified of the color of a picture to be stopped on the winning line, the operation order of the stop button, or the like by a sub-reel provided separately from the three reels, a liquid crystal panel, or voice. When the player operates the stop button in accordance with this notification, it becomes easier to win the small part that has won the internal prize, so the probability of gaining profits increases.
[0005]
In addition to the AT mode, the special mode includes other game modes such as a challenge time (CT) mode, a replay time (RT) mode, and an assist replay time (ART) mode. The CT mode is a game mode in which the reel stop control by the reel stop control means is suppressed, and the reel stop control is performed with priority given to the operation timing of the stop button operation. The RT mode is one of the winning roles, and the probability of replay that allows the next game to be played without inserting medals is higher than the normal mode in a predetermined number of games. It is a game mode that allows a game to be played while suppressing consumption of the game. In the game in the RT mode, the winning combination determination table used by the winning combination determining means is provided separately from the winning combination determination table for the normal mode, and is set so that the winning probability of replay is higher than in the normal mode. The winning combination is determined by switching to the winning combination determination table for the RT mode. The ART mode is a game mode in which the functions of the AT mode and the RT mode are combined. In the predetermined number of games, the winning probability of the replay is higher than that in the normal mode, and when a small role is won, This is a game mode in which the player is notified of the color of the winning picture to be stopped on the winning line and the operation order of the stop button.
[0006]
The models provided with the AT mode include those that shift to the AT mode after the end of the BB mode and those that shift to the AT mode when winning the transition lottery, and the triggers for starting the AT mode vary depending on the model. . In the case where the transfer lottery is performed, for example, a lottery of whether or not to grant the right to shift to the AT mode is first performed, and when the lottery is won, the number of times to shift to the AT mode is also determined simultaneously. When the right to shift to the AT mode is granted, a lottery to shift to the AT mode is performed in a game to be continued, and when the shift lottery is won, the mode is shifted to the AT mode. Further, when the right to shift to the AT mode is granted a plurality of times, the transfer lottery is performed again in the game after the end of the AT mode. The winning probability of the transfer lottery is set high so that the game can be transferred to the AT mode after only a few games. If the right to transfer to the AT mode is obtained multiple times, the game will repeatedly enter the AT mode in a short period of time. A lot of medals.
[0007]
[Problems to be solved by the invention]
However, in the above slot machine, the winning probability of the lottery for shifting to the AT mode is set to be constant, so if the winning probability is set high so that it is repeatedly shifted to the AT mode in a short period of time, the right is obtained. There has been a problem that when the game has been transferred to the AT mode for a certain number of times and the game has been played to some extent, the player has perceived that all rights to the AT mode have been consumed. This not only reduced the player's expectation for the game, but also caused the operation rate of the slot machine to decrease as the game ended. In order to prevent this, it is conceivable that the winning probability of the transition lottery is set low, but in this case, since the number of games played during the AT mode increases, the game may be delayed and lack of tension. There is.
[0008]
In order to solve the above-mentioned problems, the present invention provides a sense of tension in a game performed between special modes when it is decided to shift to a special mode in which a player's reel stop mode is notified a plurality of times. It is an object of the present invention to provide a gaming machine, a program, and a recording medium that can be provided.
[0009]
[Means for Solving the Problems]
  In order to achieve the above object, the gaming machine of the present invention includes a winning combination determining means for determining either a loser or a plurality of types of winning combinations by lottery, and a game in a normal mode and a special mode is performed. In the game of the special mode, in the gaming machine that makes it easy to obtain a privilege on the game for a predetermined number of game periods, the game is shifted to the special mode according to the type of the loser or the winning combination selected by the winning combination determining means. Whether or not to grant the right is determined by lottery, and when it is determined to grant the right to shift to the special mode, the special mode transition number lottery means for determining the number of transitions by lottery, and the number of the special mode transition times After the right to shift to special mode is granted by lottery means, shift from normal mode to special modeIs determined by lottery, and if this lottery is won, the mode is shifted to the special mode.Special mode transition means,When the number of times of transition to the special mode reaches a predetermined number, the special mode transition probability table used in the lottery by the special mode transition means is selected from among a plurality of special mode transition probability tables having different transition probability to the special mode. Special mode transition probability table determination means determined by lottery andIt is equipped with.
[0010]
As the special mode, it is effective to provide an AT mode, a CT mode, an RT mode, an ART mode, etc. in order to increase the interest of the game. The AT mode is a game mode in which, in a predetermined number of games, the player is notified of the color of the winning pattern to be stopped on the winning effective line and the operation sequence of the stop button when winning a small role.
[0011]
The CT mode is a game mode in which the reel stop control by the reel stop control means is suppressed, and the reel stop control is performed with priority given to the operation timing of the stop button operation.
[0012]
The RT mode is one of the winning roles, and the probability of replay that allows the next game to be played without inserting medals is higher than the normal mode in a predetermined number of games. It is a game mode that allows a game to be played while suppressing consumption of the game. In the game in the RT mode, the winning combination determination table used by the winning combination determining means is provided separately from the winning combination determination table for the normal mode, and is set so that the winning probability of replay is higher than in the normal mode. The winning combination is determined by switching to the winning combination determination table for the RT mode.
[0013]
The ART mode is a game mode in which the functions of the AT mode and the RT mode are combined. In the predetermined number of games, the winning probability of the replay is higher than that in the normal mode, and when a small role is won, This is a game mode in which the player is notified of the color of the winning picture to be stopped on the winning line and the operation order of the stop button.
[0014]
Further, when the number of times of transition to the special mode reaches a predetermined number, the special mode transition probability table used in the lottery by the special mode transition means is determined by lottery from a plurality of special mode transition probability tables. It is preferable to provide a special mode transition probability table determination means. As a result, for example, when a special mode transition probability table with a low transition probability is drawn, the player will not be able to detect even if the number of times of the game is shifted to the special mode. More tension can be given to the game.
[0015]
  Also,Used in the lottery in the special mode transition number lottery means, provided a transition number determination table assigned a plurality of discontinuous transition number,
If the right to transition to the special mode remains, in the game from the end of the special mode of the number of transitions assigned in the transition number determination table to the transition to the subsequent special mode, A special mode transition probability table with a low transition probability to the special mode is used to perform a lottery by the special mode transition means, and a special mode that follows after the special mode with the number of transitions not assigned to the transition number determination table ends. A special mode transition probability table switching means is provided in the game until transition to the mode, in which a lottery is performed by the special mode transition means using a special mode transition probability table having a relatively high probability of transition to the special mode.It is preferable. As a result, if the number of transitions to the special mode until the next special mode is one of a plurality of types of transitions set in advance, the transition to the special mode is made with a small number of games. It is possible to prevent the game from being delayed.
[0016]
Further, when a bonus game mode executing means for executing a bonus game mode in which a probability of giving a profit to a player is higher than that in the normal mode is provided, the special mode transition means is the game in the bonus game mode, It is preferable to provide special mode execution means for shifting to the special mode following the bonus game mode in response to the right to shift to the special mode being granted by the special mode shift frequency lottery means. As a result, it is possible to make a transition to the special mode and the bonus game mode continuously, and the player can have a sense of expectation for acquiring a large number of medals in a short period of time. You can increase your sense of anticipation for the game with a sense of happiness.
[0017]
Furthermore, a bonus game mode executing means for executing a bonus game mode in which the probability of giving a player a profit is higher than that in the normal mode is provided, and a game number count for counting the number of games played after the bonus game mode is ended. And when the number of games counted by the game number counting means reaches a predetermined number, the special mode transition number lottery means grants the right to shift to the special mode. The mode shift means preferably shifts from the next game to the special mode. As a result, after the bonus game mode ends, it is possible to play a small number of games and shift to the special mode, and the player has a sense of expecting to acquire a large number of medals in a short period of time. Therefore, it is possible to increase the sense of expectation for the game by encouraging the gambling feeling of the player.
[0018]
  In order to achieve the above object, the present inventionThe program is based on a winning combination determining means for determining one of a winning combination and a plurality of types of winning combinations by lottery, and a type of winning or winning combination selected by the winning combination determining means.It's easier to get in-game benefits than in normal modeWhether or not to grant the right to shift to the special mode is determined by lottery, and when it is determined to grant the right to shift to the special mode, the special mode transition number lottery means for determining the number of transitions by lottery, After the right to shift to the special mode is granted by the special mode shift frequency lottery means, the normal mode is shifted to the special mode.Is determined by lottery, and if this lottery is won, the mode is shifted to the special mode.Special mode transition means,When the number of times of transition to the special mode reaches a predetermined number, the special mode transition probability table used in the lottery by the special mode transition means is selected from among a plurality of special mode transition probability tables having different transition probability to the special mode. Special mode transition probability table determination means determined by lotteryIt is for functioning the computer of the gaming machine.
[0019]

[0020]
DETAILED DESCRIPTION OF THE INVENTION
The slot machine 10 shown in FIG. 1 is provided with a normal mode, a BB mode as a bonus game mode, and an AT mode as a special mode. The BB mode is terminated when the game is shifted to the RB mode three times or when the game in the RB introduction mode is performed 30 times. In the RB introduction mode, the game is played by inserting 1 to 3 medals, and the winning probability of the small role is increased. In a game in the RB introduction mode, the winning combination for shifting to the RB mode is won, and when the winning combination is won, the mode is switched to the RB mode. The RB mode ends when a predetermined winning combination is won eight times or when 12 games are played. In the AT mode, when the AT lottery is won, the right to shift to the AT mode is obtained, and the number of times to shift to the AT mode in the AT lottery is determined at the same time. The number of transitions to the AT mode is determined as 1, 3, or 5 times.
[0021]
The AT lottery is performed in a normal mode game when a loser or a specific winning combination (for example, cherry) is won, or in an RB introduction mode game when a lost or specific winning combination is won. When the AT lottery is won in the game in the normal mode, the AT transition lottery is performed from the next game, and when the lottery is won, the mode is shifted to the AT mode. If the AT lottery is won in the game in the RB introduction mode, the AT shift lottery is not performed and the AT mode is shifted to the BB mode. If the AT lottery is won within 100 games after the end of the BB mode, the AT transition lottery is not performed and the next game is shifted to the AT mode. One AT mode ends when the game is played 13 times.
[0022]
In the slot machine 10, four display windows 13 are provided in the front door 12 of the housing 11, and the first reel 14 a, the second reel 14 b, the third reel 14 c, and the sub reel 15 rotate behind each display window 13. Built in freely. As is well known, a plurality of types of winning 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, each of which has a pattern of each reel, are set, with three horizontal lines and two diagonal lines.
[0023]
Prior to the start of the game, when one medal is inserted from the medal slot 16, the winning line in the center is activated, 3 for 3 in the side, and 2 for the 3 in addition to the diagonal 5 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, four symbols per reel can be observed from the display window 13, and in addition to the four horizontal winning lines, another prize that is folded to combine one symbol for each reel. It is also possible to set an effective line.
[0024]
The rightmost sub-reel 15 functions as a notification means, and rotates together with the first to third reels 14a to 14c by operating the start lever 18 when a predetermined winning combination (for example, bell) is won in an AT mode game. Begin. On the outer periphery of the sub reel 15, a plurality of types of patterns indicating the order of performing the stop operation of the first to third reels 14a to 14c are drawn, and in addition to these, a blank portion where nothing is drawn is also provided. . It should be noted that the pattern drawn on the outer periphery of the sub reel 15 is preferably an appropriate pattern, and is not limited to the pattern, and may be a mark or a number, for example. In addition, on the sub-reel 15, an appropriate notification is drawn by appropriately drawing a picture such as a picture indicating that a specific winning combination has been won or a picture indicating an expectation level regarding whether or not a specific winning combination has been won. It's okay.
[0025]
The sub-reel 15 is normally stopped at a position where a blank portion is displayed, and a position where a reel stop operation sequence that enables winning of the winning bell when winning a bell in an AT mode game is displayed. Stopped at. The player can reliably win the bell by operating the stop buttons 19a to 19c according to the order displayed by the sub reels 15. The predetermined winning combination is not limited to the bell and is preferably set to an appropriate winning combination.
[0026]
By operating these stop buttons 19a to 19c, the first to third reels 14a to 14c corresponding to the buttons are individually stopped. The operation panel above the stop buttons 19a to 19c is provided with various operation buttons such as a 1-bet button, a MAX bet button, and a payout button that are operated when a game is played in a state where medals are credited. Since the functions of these operation buttons are well known, the details thereof are omitted.
[0027]
A medal tray 20 is provided at the lower portion of the housing 11, and a payout medal obtained when a winning is obtained in the game is paid out from the payout opening 21 to the medal tray 20.
[0028]
As shown in FIG. 2, the operation of the slot machine 10 is basically controlled by a microcomputer including a CPU 30 and a memory 31. In addition to the control unit 30a, the CPU 30 is provided with an electronic lottery unit 39, a winning combination determining unit 40, an AT control unit 41, and a game number counter 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 control unit 30a. A selector is incorporated in the back of the medal insertion slot 16 and an inappropriate medal is discharged to the medal tray 20. Further, when a selector inserts a medal at an inappropriate timing, for example, a medal inserted in the middle of a game or with various operation buttons pressed, without passing through the medal sensor 32. The medal tray 20 is discharged.
[0029]
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. In addition, when a game is performed and a winning with a medal payout is obtained, the payout medal is also credited, and the credited medal is paid out to the tray 20 when the payout button is operated.
[0030]
The control unit 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).
[0031]
The start signal sensor 33 inputs a game start signal to the control unit 30a when the start lever 18 is operated after 1 to 3 medals are inserted. Upon receiving the game start signal, the control unit 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. The game execution program includes execution programs for the BB mode and the AT mode, and the control unit 30a reads the execution programs to execute the game in each mode. In the AT mode game, the sub reel 15 is rotated simultaneously with the rotation of the first to third reels 14a to 14c. As a result, the control unit 30a functions as bonus game mode execution means.
[0032]
The reel drive controller 34 controls the drive and stop of each reel. Each reel is fixed to a drive shaft of an individual stepping motor 35a to 35d, and each reel is controlled by controlling the driving of each stepping motor 35a to 35d. 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.
[0033]
Since the stepping motors 35a to 35d rotate at a rotation angle corresponding to the number of supplied drive pulses, the control unit 30a controls the number of supplied drive pulses to control the first to third reels 14a to 14c and the sub reels 15. The rotation angle can be controlled, and the stop position of the reel can be determined by stopping the supply of the drive pulse. Each reel is integrally formed with reflection signal portions 36a to 36d at the reference position, and the photosensors 37a to 37d photoelectrically detect the passage of each reflection signal portion for each rotation. Detection signals from the photosensors 37a to 37d are input to the control unit 30a as a reset signal for each reel.
[0034]
A pulse counter is provided for each of the stepping motors 35a to 35d in the control unit 30a, and counts the number of drive pulses supplied to each of the stepping motors 35a to 35d. When the reset signal is input from the photosensors 37a to 37d, 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.
[0035]
A picture table is stored in the ROM area of the memory 31, and the picture table represents the number of drive pulses corresponding to the rotation angle from the reference position of each reel, and the picture representing each picture 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 pattern 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 pattern will move on the winning line.
[0036]
The stop button sensors 38a to 38c input a stop signal for each reel to the control unit 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. For the bell, stop control of the first to third reels 14a to 14c is performed so that a winning is made only when the stop buttons 19a to 19c are operated in a predetermined order.
[0037]
The stop control of the first to third reels 14a to 14c is performed within the range of four winning designs (retraction range). For example, when the stop buttons 19a to 19c are operated, the control is positioned on the winning line. If the winning symbols that make up the winning combination won in the lottery are included in the four winning symbols that are consecutive from the selected winning symbols, the process until the first to third reels 14a to 14c stop The time is delayed, and the winning designs that make up the winning combination are stopped on the winning line. In addition, if the bell pattern which comprises a bell is arranged so that the space | interval of bell patterns may be within four winning designs, and the operation sequence of stop button 19a-19c is correct, it will be a prize regardless of operation timing. Thus, stop control of the first to third reels 14a to 14c is performed. As described above, the control unit 30a and the reel drive controller 34 function as reel stop control means.
[0038]
The control unit 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 the game is started. The random value selected by lottery is input to the winning combination determining unit 40. The winning combination determining unit 40 determines what winning combination is to be given in the currently executed game according to the input value. Thus, the electronic lottery unit 39 and the winning combination determining unit 40 function as a winning combination determining unit.
[0039]
The winning combination determination unit 40 is provided with a plurality of winning combination determination tables in which random values are grouped according to their sizes. In the first winning combination determination table, a random number sampled in the game in the normal mode is a BB that gives the right to shift to the BB mode, a small combination corresponding to a small combination winning pattern that only pays out a predetermined number of medals, This is used to determine which picture belongs to, such as replay that gives the right to play the next game with the same number of bets without inserting medals, or lose that does not generate any hits, that is, winning determination. Note that there are a plurality of types of small role winning designs, and a payout medal is assigned to each. Then, the winning type and the design are determined depending on which winning design the sampled random number value belongs to.
[0040]
In addition to the first winning combination determination table, the winning combination determination unit 40 is provided with a winning combination determination table used in the BB mode and the RB mode. When the winning combination is determined by the winning combination determination unit 40, a winning combination determination signal indicating the determined loss or the type of winning combination is input to the control unit 30a.
[0041]
As shown in FIG. 3, the AT control unit 41 includes an AT lottery unit 50, an AT right grant determination table 51a, a transition number determination table 51b, an AT flag memory 52, an AT transition lottery unit 53, a table switching signal generation unit 54, a table. It comprises a selection lottery unit 55, an AT transition probability selection table 56, a first transition determination unit 57, and a second transition determination unit 58.
[0042]
The AT lottery unit 50, the AT right grant determination table 51a, and the transition number determination table 51b function as special mode transition number lottery means, and the AT lottery unit 50 when the winning combination determining unit 40 determines a lose or cherry. Is operated and an AT lottery is performed. The AT lottery unit 50 includes a random number generator and a random number sampling circuit, and samples random number values each time it is activated. The sampled random number is first checked against the AT right grant determination table 51a to determine whether or not to grant the right to shift to the AT mode. When it is determined to give the right to shift to the AT mode, the sampled random number value is checked against the shift count determination table 51b to determine the number of shifts to the AT mode. In the migration count determination table 51b, the random value groups are divided into groups for each migration count. The group for each number of times of transition is composed of three types of groups in which the number of times of transition to the AT mode is once, three times, and five times. When it is determined to give the right to shift to the AT mode, the determined number of AT flags are written in the AT flag memory 52. When one AT flag is read, the mode is shifted once to the AT mode.
[0043]
The AT transition lottery unit 53 is activated when the right to shift to the AT mode is determined by the lottery performed by the AT lottery unit 50 and is activated when the number of times of transition to the AT mode is determined. Is called. The random number value sampled by the AT transition lottery unit 53 is input to the first transition determination unit 57 or the second transition determination unit 58 according to the number of times of transition to the AT mode. The first transition determination unit 57 includes an AT low transition probability table 59 and an AT high transition probability table 60. The AT low transition probability table 59 and the AT high transition probability table 60 are grouped with random values so that the probability of transition to the AT mode is different from each other (for example, the AT low transition probability table 59 is 1/12, the AT high transition probability table 59). Whether the transition probability table 60 is 1/4), whether the random number value sampled by the AT transition lottery unit 53 is collated with any table according to the number of times of transition to the AT mode, and whether or not to transition to the AT mode. Is determined.
[0044]
The second transition determining unit 58 includes an AT low transition probability table 61, an AT transition probability table 62, and an AT high transition probability table 63. As with the first transition determining unit 57, the sampled random number value is any one. Whether or not to shift to the AT mode is determined by checking with the table. In the AT low transition probability table 61, the AT transition probability table 62, and the AT high transition probability table 63, random numbers are grouped so that the probability of transition to the AT mode is different from each other (for example, the AT low transition probability table 61 is 1). / 15, the AT transition probability table 62 is 1/5, and the AT high transition probability table 63 is 1/3). When it is determined to shift to the AT mode, an AT mode shift signal is input to the control unit 30a, and the next game is shifted to the AT mode. As a result, the control unit 30a and the AT transition lottery unit 53 function as special mode transition means.
[0045]
The table selection signal generation unit 54 inputs a table selection signal indicating the type of the transition probability table used in the lottery in the AT transition lottery unit 53 in the AT mode to the AT transition lottery unit 53. The table selection signal generator 54 receives a transition frequency signal indicating the number of transitions to the AT mode counted by the controller 30a or a lottery result signal from the table selection lottery unit 55 described later. The table selection signal generator 54 determines the type of table selection signal to be output according to the input signal. As a result, the controller 30a and the table selection signal generator 54 function as table switching means.
[0046]
The table selection lottery unit 55 is operated after the number of times of shifting to the AT mode reaches a predetermined number. The random value sampled by the table selection lottery unit 55 is checked against the AT transition probability selection table 56. In the AT transition probability selection table 56, three tables, an AT low transition probability table 61, an AT transition probability table 62, and an ATAT high transition probability table 63, are assigned to grouped random values, and sampled random values And which table is used to determine the AT transition lottery. As a result, the table selection lottery unit 55 and the AT transition probability selection table 56 function as special mode transition probability table determination means.
[0047]
The game number counter 42 functions as a game number counting means, and is operated after the BB mode ends. A game start signal is input to the game number counter 42 every time a game is played, and the number of times the game is played is counted. The count value of the game number counter 42 is monitored by the control unit 30a and cleared when the counted number of games reaches a predetermined number (for example, 100 times).
[0048]
The medal hopper 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. Note that a payout table in which the number of payout medals is determined for each type of winning combination is stored in the ROM area of the memory 31, and the control unit 30a reads this to drive the medal hopper 43.
[0049]
Next, the operation of the slot machine configured as described above will be described. As shown in FIGS. 4 and 4, when 1 to 3 medals are inserted prior to the start of the game in the normal mode, the number of inserted medals is counted by the control unit 30a. Thereafter, when a game start operation is performed by the start lever 18, a game start signal is input from the start signal sensor 33 to the control unit 30a, and rotation of the first to third reels 14a to 14c is started.
[0050]
At the same time, the electronic lottery unit 39 samples a random number, compares the value with the first winning combination determination table of the winning combination determining unit 40 to determine the type of the lost or winning combination, and the winning combination determination signal is sent to the control unit 30a. Feedback. When the type of winning combination is determined by the winning combination determining unit 40, the operation of the stop buttons 19a to 19c is validated. The control unit 30a monitors the operation timing of the stop buttons 19a to 19c while referring to the count value of the pulse counter provided for each reel, and the winning pattern determined by the winning combination determining unit 40 is on the winning active line. Stop control of the first to third reels 14a to 14c is performed so as to easily stop.
[0051]
When the winning combination determining unit 40 determines a loss or cherry, the control unit 30a activates the AT lottery unit 50. The AT lottery unit 50 samples one random value. The sampled random number value is checked against the AT right grant determination table 51a to determine whether or not to grant the right to shift to the AT mode, and when it is determined to grant the right to shift to the AT mode. The sampled random number value is collated with the transition number determination table 51b, and the transition number is also determined at the same time. The result of the AT lottery is input to the control unit 30a. When the AT lottery is won, AT flags corresponding to the determined number of times are written in the AT flag memory 52. Then, the AT transition lottery unit 53 is operated from the next game, and the AT transition lottery is performed.
[0052]
The control unit 30 a inputs a transition number signal indicating the first AT mode to the table selection signal generation unit 54. The table selection signal generator 54 inputs a table selection signal indicating the AT low transition probability table 59 to the AT transition lottery section 53. In response to this, the random value sampled by the AT transition lottery unit 53 is checked against the AT low transition probability table 59 of the first transition determining unit 57 to determine whether or not to shift to the AT mode. When it is determined to shift to the AT mode in the AT shift lottery, an AT mode shift signal is input to the control unit 30a. In response to the AT mode transition signal, the control unit 30a reads one AT flag written in the AT flag memory 52, subtracts "1", and reads the AT mode execution program from the ROM area of the memory 31. Transition to AT mode.
[0053]
In the AT mode game, when the bell is won, the sub reels 15 are simultaneously rotated together with the first to third reels 14a to 14c. The control unit 30a performs stop control of the sub reel 15 so that the sub reel 15 stops at a position where the operation order of the stop buttons 19a to 19c that can make the bell win. The player can reliably win the bell by operating the stop buttons 19a to 19c in accordance with the operation order displayed on the sub reel 15. Thereby, the AT mode game can increase medals. The AT mode ends when the game is played 13 times.
[0054]
When the AT mode is finished and the AT flag is written in the AT flag memory 52, that is, when it is decided to give the right to shift to the AT mode three or five times by the AT lottery, the control unit 30a The AT shift lottery unit 53 is operated again, and a shift number signal indicating that the next AT mode is the next time is input to the table selection signal generation unit 54. A table selection signal indicating the AT low transition probability table 59 is input from the table selection signal generator 54 to the AT transition lottery section 53. In response to this, the AT transition lottery unit 53 performs AT transition lottery by comparing the sampled random number value with the AT low transition probability table 59 of the first transition determination unit 57. When the AT transition lottery is won, the second AT mode is entered. In this case, since the AT transition lottery is performed using the AT low transition probability table 59, it is difficult to transition to the AT mode. This makes it difficult for the player to determine whether the determined number of transitions to the AT mode is one or more, and only by playing a small number of games. it can.
[0055]
When the second AT mode ends, the control unit 30a operates the AT shift lottery unit 53 and inputs a shift number signal indicating that the next AT mode is the next time to the table selection signal generation unit 54. A table selection signal indicating the AT high transition probability table 60 is input from the table selection signal generator 54. In response to this, the AT transition lottery unit 53 performs AT transition lottery by comparing the sampled random number value with the ATAT high transition probability table 60 of the first transition determination unit 57. The number of transitions to AT mode is one, three, or five, so when transitioning to the second AT mode, transition to AT mode is reliably performed three or five times. . For this reason, it is possible to prevent the game from being delayed by increasing the winning probability of the AT shift lottery after shifting to the second AT mode. When the AT shift lottery is won, the mode is shifted to the third AT mode.
[0056]
When the third AT mode is completed and the AT flag is written in the AT flag memory 52, that is, when it is determined that the number of times of shifting to the AT mode in the AT lottery is five, the control is performed. The unit 30a again causes the AT transition lottery unit 53 to perform the AT transition lottery using the AT low transition probability table 59. When the AT shift lottery is won, the mode is shifted to the fourth AT mode. In this case, since the AT transition lottery is performed using the AT low transition probability table 59, it is difficult to transition to the AT mode. This makes it difficult for the player to determine whether the determined number of transitions to the AT mode is 3 or 5 or only by playing a small number of games. it can.
[0057]
When the fourth AT mode is completed and the AT flag is written in the AT flag memory 52, the control unit 30a operates the AT shift lottery unit 53. Further, the table selection lottery unit 55 is operated to perform table selection lottery. The random number sampled by the table selection lottery unit 55 is checked against the AT transition probability selection table 56, and a transition probability table used in the AT transition lottery is determined. When the lottery is completed, a lottery result signal is input to the table selection signal generator 54. In response to this, the table selection signal generator 54 is activated, and a table selection signal indicating the determined type is input to the AT transition lottery unit 53.
[0058]
The AT transition lottery unit 53 is the transition determined by the lottery in the table selection lottery unit 55 among the AT low transition probability table 61, the AT transition probability table 62, and the AT high transition probability table 63 of the second transition determination unit 58. AT transfer lottery is performed using the probability table. Since the number of times of shifting to the AT mode is one time, three times, or five times, when the mode is shifted to the fourth AT mode, the mode is surely shifted to the AT mode five times. Since the combined probability (3/5) of each transition probability table of the second transition determination unit 58 is set to be higher than the winning probability of the AT low transition probability table 59, it is possible to prevent the game from being delayed. it can. In addition, since the winning probability of the AT transition lottery is selected by lottery from three types of probabilities, it is possible to prevent the game from becoming monotonous. When the AT transition lottery is won, the mode is shifted to the fifth AT mode, and when the AT mode ends, the mode is shifted to the normal mode.
[0059]
In addition, as a preliminary knowledge when playing a game that the number of times of transition to the AT mode is any one of 1, 3, and 5 times, for example, a sticker or the like is attached to the housing 11 or the game hall If the player is informed by a method such as distributing a strategy booklet describing the gaming method of the slot machine 10, when the present invention is implemented, the player may feel nervous in the game between the AT modes. It becomes more effective.
[0060]
In addition, when a BB is won in the game in the normal mode, when this is won, a payout medal is paid out and the mode is changed from the normal mode to the BB mode. When the mode is shifted to the BB mode, the winning combination determination table is switched, and the game in the RB mode and the RB introduction mode which is shifted before the RB mode is performed. In the RB introduction mode, the game is played with 1 to 3 medal bets. In a game in the RB introduction mode, the winning combination for shifting to the RB mode is won, and when the winning combination is won, the mode is switched to the RB mode. In the RB mode, when a predetermined winning combination is won or when 12 games are played, the game ends. The BB mode is ended when the game in the RB introduction mode is performed 30 times or when the game is shifted to the RB mode three times.
[0061]
Even when a game in the RB introduction mode is won by losing or cherry, the AT lottery unit 50 is operated to perform AT lottery. When the AT lottery is won during the RB introduction mode, the AT flag memory 52 is written with the determined number of AT flags. Then, the control unit 30a starts the first AT mode after the end of the BB mode. If it is decided to shift to AT mode 3 or 5 times, as described above, the number of transitions to AT mode will be the same as when the AT lottery was won during the normal mode except within 100 games after the end of BB. Accordingly, the transition probability table is selected and determined by lottery. In this case, since the mode is shifted to the AT mode following the BB mode, the player can acquire a large number of medals in a short period of time. For this reason, the player's interest in the BB mode can be enhanced.
[0062]
If the AT lottery in the game in the RB introduction mode is not won, the mode is shifted to the normal mode when the BB mode is finished. In this case, the control unit 30a activates the game number counter 42 to monitor the number of games played after the BB ends. When the AT lottery is won within 100 games after the BB is finished, the control unit 30a shifts to the first AT mode from the next game. If it is decided to enter the AT mode 3 or 5 times, the probability of transition depending on the number of transitions to the AT mode in the same way as when the AT lottery was won during the normal mode except within 100 games after the end of the BB Decisions are made by table selection and lottery. Also in this case, if the AT lottery is won, the player can acquire a large number of medals in a short period of time because the game is shifted to the AT mode after a few games after the BB mode is finished become. For this reason, the interest to the game after completion | finish of BB mode of a player can be heightened.
