<4-1. Process flow>
(1) Medals Accepting Process When a medal is inserted into the medal insertion slot 10, the slot machine 1 accepts the inserted medal and takes it into the slot machine 1 or accepts the inserted medal in the medal tray 40. (Sa501).

  Specifically, when the bet number is 3 and the credit number is less than 50, when a medal is inserted into the medal slot 10, the CPU 101 takes the inserted medal into the slot machine 1 and inserts it. Add credits by the number of medals. When the bet number is 3 and the credit number is 50, when a medal is inserted into the medal insertion slot 10, the CPU 101 drives a solenoid provided in the medal detection device to insert the inserted medal into the medal tray 40. Return to

(2) Bet processing The slot machine 1 sets the number of bets necessary for starting the game in accordance with the insertion of medals into the medal insertion slot 10, the operation of the bet button 11, or the winning of the re-gamer (Sa502). .

  Specifically, when a bet is less than 3, when a medal is inserted into the medal slot 10, the CPU 101 adds the bet number by the number of inserted medals. When the bet button 11 is operated when the bet number is less than 3, the CPU 101 subtracts the credit number and adds the bet number. When the re-gamer wins, the CPU 101 executes an automatic bet process for betting again the bet number bet on the game without subtracting the credit amount.

(3) Lever Acceptance Processing The slot machine 1 starts the game when the operation of the start lever 12 is accepted with three medals bet (Sa503). Specifically, when the start lever 12 is operated with the bet number set to 3, the CPU 101 executes a game process after an internal lottery process described later. On the other hand, when the start lever 12 is operated with the bet number set to less than 3, the CPU 101 does not execute the game process after the internal lottery process.

(4) Internal lottery process With the start of the game, the slot machine 1 determines by lottery the winning of one or more roles from a plurality of predetermined roles or a loss that does not win any of the roles (Sa504). When the start lever 12 is operated with the bet number set to 3, the CPU 101 executes an internal lottery process. Details of the internal lottery process will be described later.

(5) Reel Rotation Process The slot machine 1 rotates each of the reels R1 to R3 in order to variably display the symbols arranged on the reel R along with the execution of the internal lottery process (Sa505). Specifically, the CPU 101 rotates each of the reels R1 to R3 by continuously supplying pulses to each of the stepping motors 54a to 54c. Details of the reel rotation processing will be described later.

(6) Reel Stop Processing When the stop button 13 is operated while the reel R is rotating, the slot machine 1 stops the rotation operation of the reel R (Sa506). When the stop button 13 is operated while the reel R is rotating, the CPU 101 supplies a predetermined pulse to the stepping motor 54 to which the reel R corresponding to the operated stop button 13 is fixed, so that the corresponding reel R Stop rotating operation. Details of the reel stop process will be described later.

(7) Symbol Determination Process The slot machine 1 determines the symbol combination that is stopped and displayed on the winning line L after all of the reels R1 to R3 are stopped (Sa507). After all of the reels R1 to R3 are stopped, the CPU 101 determines whether or not the symbol combination stopped and displayed on the winning line L is a predetermined symbol combination determined in advance. Details of the symbol determination process will be described later.

(8) Bonus granting process The slot machine 1 executes a process of granting a bonus corresponding to the winning combination when it is determined that the winning combination is won by the symbol determining process (Sa508). Details of the privilege grant processing will be described later.

<4-2. Detailed explanation of each processing>
Details of each process relating to the above-described one-time game will be described.

(1) Details of Internal Lottery Processing Details of the internal lottery processing in the slot machine 1 will be described. The internal lottery process is a process for determining, by lottery, a winning of one or a plurality of roles or a winning that does not win any of the roles from a plurality of predetermined roles, using the internal lottery table shown in FIG. Executed. In the internal lottery table, a correspondence relationship between one or a plurality of winning combinations and a lottery value indicating a lottery probability is defined.

  When the CPU 101 receives the operation of the start lever 12, the CPU 101 acquires one random value from a range of 0 to 65535 from a random number generator (not shown). Next, a corresponding lottery value is specified while sequentially comparing the acquired random value with a plurality of lottery values defined in the internal lottery table. More specifically, the CPU 101 compares the random value acquired from the random number generator with the first lottery value in the internal lottery table. As a result of the comparison, if the random value is less than the lottery value, the winning of the combination associated with the first lottery value is determined. If the random value is greater than or equal to the lottery value, the random value is compared with a value obtained by adding the second lottery value to the first lottery value. As a result of the comparison, if the random value is less than the sum of the first and second lottery values, the winning combination of the combination associated with the second lottery value is determined.

  In this way, the combination associated with the Nth lottery value when the random number value is repeated until the random value becomes less than the total value of the first to Nth lottery values is determined as the winning combination. For example, when the random number value acquired from the random number generator is 3077, the CPU 101 adds the second lottery value (2500) to this value because the random number value is not less than the first lottery value (300). Since the random value (3077) is equal to or greater than the total value (2800) of the first and second lottery values, the third lottery value (500) is added thereto. Since the random value (3077) is less than the total value (3300) of the first to third lottery values, the winning of the “watermelon 1” role associated with the third lottery value (500) is determined.

  As described above, in the internal lottery process, the lottery value corresponding to the random value acquired from the random number generator is specified using the internal lottery table, and the winning combination corresponding to the specified lottery value is determined. In the present specification, a group of roles to be drawn as a result of the internal lottery process (a group to which one or more roles that can be determined as a result of the internal lottery process belong) is defined in the plurality of internal lottery tables. It may be referred to as a lottery target N in association with each lottery value.

(2) Details of Reel Rotation Processing Details of the reel rotation processing in the slot machine 1 will be described. As described above, the slot machine 1 rotates the reel R by supplying pulses to the stepping motor 54.

(2-1) Waiting Process The slot machine 1 executes a waiting process for securing the minimum game time between the respective games prior to the reel R rotating operation. A flow of processing related to weight processing in the reel rotation processing will be described with reference to FIG.

  First, the slot machine 1 determines whether or not the value of the interval timer has passed the minimum game time (Sa701). Specifically, the CPU 101 determines whether or not the value of the interval timer stored in the RAM 105 exceeds the minimum game time. In the slot machine 1, the minimum game time is preset to 4.1 seconds. When the CPU 101 determines that the value of the interval timer exceeds the minimum game time, the CPU 101 proceeds the processing (Sa701: YES), and when it determines that the value of the interval timer does not exceed the minimum game time. The process waits until the value of the interval timer exceeds the minimum game time (Sa701: NO). This is weight processing for ensuring the minimum game time between games in the slot machine 1.

  When the CPU 101 determines that the value of the interval timer exceeds the minimum game time, the CPU 101 resets the value of the interval timer to 0 (Sa702) and starts counting the interval timer (Sa703). The CPU 101 executes the subsequent processing after resetting the interval timer to start timing.

  As described above, in the slot machine 1, the interval between the games is the minimum game time by the wait process executed after receiving the operation of the start lever 12 with three medals bet. It is controlled to be 1 second or longer.

  The reel R continues to rotate until the stop button 13 is operated after the reel R starts rotating. During this time, the interval timer is timed. Accordingly, the longer the period from when the reel R starts rotating until the stop button 13 is operated, the shorter the waiting time in the wait process in the next game, and after the reel R starts rotating. The shorter the period until the stop button 13 is operated, the longer the waiting time in the wait process in the next game. Thus, the waiting time in the weight process in the next game changes according to the period from when the reel R starts rotating until the stop button 13 is operated by the player.

(2-2) Basic Process The slot machine 1 rotates the reel R by supplying a pulse to the stepping motor 54 after the above-described wait process. The main control board 100A (CPU 101) holds the number of steps of the pulses supplied to each reel R in the RAM 105, and each time the pulse is supplied to each reel R, the number of steps is added and updated. When the reel position detection signal 155 output from the reel position detection sensor 55 is input, the CPU 101 resets the number of steps for the corresponding reel R to zero.

  As described above, the CPU 101 can determine that the reel rotation position is at the reference rotation position at the time when the reel position detection signal 155 is input. Therefore, by managing the number of steps supplied from the reference rotation position, The rotational position of the reel can always be grasped.

  With reference to FIG. 8, the flow of processing related to basic processing in the reel rotation processing of the slot machine 1 will be described. This process is a process executed in the interrupt program executed by the CPU 101 described above, and is executed every time an interrupt occurs periodically after the reel R rotation operation is started. This process is a process executed for one reel R. When a plurality of reels R is rotating, the process is executed for each reel R that rotates.

  In the reel rotation process, the CPU 101 supplies a pulse (stepping motor drive signal) to the stepping motor 54 corresponding to the reel R that is the target of the rotation operation (Sa801). As a result, the reel R rotates by one step. In response to supplying a pulse to the stepping motor 54, the CPU 101 adds 1 to the number of steps (Sa802). Thereby, the CPU 101 can grasp the cumulative number of pulses supplied to the stepping motor 54.

  Next, the CPU 101 determines whether or not the reel position detection signal 155 is input (Sa803). When the reel position detection signal 155 is not input (Sa803: NO), it is determined whether or not the current number of steps exceeds 504 (Sa804). If the current number of steps does not exceed 504, the process is terminated as it is (Sa804: NO).

  On the other hand, when the reel position detection signal 155 is input (Sa803: YES), it is determined whether the current number of steps is less than 504 (Sa805). If the current number of steps is not less than 504 (Sa805: NO), the number of steps is reset to 0 (Sa806). Thereby, the CPU 101 can grasp the cumulative number of pulses supplied to the stepping motor 54 from the time when the rotational position of the reel R reaches the reference rotational position.

  On the other hand, when the current number of steps is less than 504 (Sa805: YES), the CPU 101 determines that the rotation operation of the reel R is in an abnormal state, and executes predetermined error processing (Sa807). This is because the rotation position of the reel R is the reference rotation before supplying the stepping motor 54 with the 504 pulses necessary to rotate one revolution from the time when the rotation position of the reel R reaches the reference rotation position. It means that the position has been reached. That is, it means that the reel has stepped out for some reason, and there is a deviation between the rotational position of the reel R recognized by the CPU 101 and the actual rotational position of the reel R.

  Further, when it is determined whether or not the current number of steps exceeds 504 (Sa804), even when the current number of steps exceeds 504 (Sa804: YES), the CPU 101 performs the rotation operation of the reel R. It is determined that there is an abnormal condition, and predetermined error processing is executed (Sa807). This is because the reel R has supplied more pulses to the stepping motor 54 than the 504 pulses required to rotate one revolution from the time when the rotation position of the reel R reaches the reference rotation position. It means that the rotational position of R has not reached the reference rotational position. That is, as in the case described above, the reel has stepped out for some reason, and there is a deviation between the rotational position of the reel R that the CPU 101 knows and the actual rotational position of the reel R. means.

  Thus, in the reel rotation process of the slot machine 1, the CPU 101 controls the rotation operation of the reel R while always grasping the current rotation position of the reel. Further, it is possible to accurately grasp that the reel R has stepped out.

(3) Details of Reel Stop Processing Details of the reel stop processing in the slot machine 1 will be described.

  FIG. 9 shows the configuration of a stop table used in the reel stop process in the slot machine 1. This stop table indicates that when the winning of “watermelon 1” is determined by the internal lottery process, the push button is pushed forward (the stop button 13a corresponding to the left reel R1, the stop button 13b corresponding to the middle reel R2, the right reel R3 The stop table used in the case where the buttons are operated in the order of the stop buttons 13c corresponding to (1).

  The “symbol number PN” is the symbol number of the symbol located on the winning line L at the timing when the stop button 13 is operated, and the “slip frame number” is the reel R when the stop button 13 is operated at the above timing. The amount of movement by which the reel R is rotationally moved before stopping is indicated by the number of symbols. For example, if the left stop button 13a is operated when the “watermelon” symbol of symbol number PN = 17 is positioned on the winning line L while the left reel R1 is rotating, the CPU 101 corresponds to symbol number PN = 17. Since the number of sliding symbols to be performed is “0”, the left reel R1 is stopped at the timing when the “watermelon” symbol of symbol number PN = 17 is positioned on the winning line L.

  When the slot machine 1 receives an operation of the stop button 13 while the reel R is rotating, the slot machine 1 stops the rotation of the reel R. More specifically, when the CPU 101 receives an operation of any one of the stop buttons 13a to 13c while the reel R is rotating, the CPU 101 executes control to stop the reel R corresponding to the stop button 13 that has received the operation. This is repeated until all of the reels R1 to R3 are stopped. At this time, the CPU 101 stops the corresponding reel R within the range of the reel rotation amount for a maximum of four symbols from the time when the stop button 13 is operated. In addition, when the winning of any combination is determined by the internal lottery process, the CPU 101 stops the reel R so that the symbol related to the winning combination is drawn on the winning line L.

  For example, in a situation where the reels R1 to R3 are rotating and the winning of “watermelon 1” is determined by the internal lottery process, the “plum” symbol of symbol number PN = 15 in the left reel R1 is displayed. When the left stop button 13a is operated at a timing on the winning line L, the left reel R1 is rotated and moved by two symbols, and the “watermelon” symbol with the symbol number PN = 17 is positioned on the winning line L. Then, the left reel R1 is stopped.

  Next, when the middle stop button 13b is operated at the timing when the “cherry” symbol of symbol number PN = 7 on the middle reel R2 is positioned on the winning line L, the CPU 101 rotates the middle reel R2 by four symbols. The middle reel R2 is stopped at the timing when the “watermelon” symbol of symbol number PN = 11 is positioned on the winning line L.

  Next, when the right stop button 13c is operated at the timing when the “bell” symbol of symbol number PN = 7 on the right reel R3 is positioned on the winning line L, the CPU 101 rotates the right reel R3 by two symbols. The right reel R3 is stopped at the timing when the “cherry” symbol of symbol number PN = 9 is positioned on the winning line L. As a result of all the reels R1 to R3 being stopped, the “watermelon” symbol (left reel R1), the “watermelon” symbol (middle reel R2), and the “cherry” symbol (right reel R3) stop on the winning line L. .

  The reason why the “watermelon” symbol is not stopped on the winning line L in the right reel R3 even though the “watermelon 1” role is determined by the internal lottery process is that the right stop button 13c is operated in the right reel R3. This is because the “watermelon” symbol does not exist between the symbol number PN = 7, which is the timing of the symbol, and the symbol number PN = 11, which is four symbols ahead. When the stop button 13 is operated at such a timing, a predetermined symbol within the range from the symbol located on the winning line L to the 4 symbols ahead at the timing when the stop button 13 is operated, Stop on the winning line L.

  As described above, the CPU 101 executes the reel stop process by using the stop table in order to acquire an appropriate number of sliding symbols according to the operation timing of the stop button 13 in response to the operation of the specific stop button 13. The stop table shown in FIG. 9 is based on the result of the internal lottery process from a plurality of element data stored in advance in the ROM 104 for constituting the stop table each time the CPU 101 executes the reel stop process. A data structure as a result of appropriately combining the specified element data is shown.

  By executing the reel stop process using the stop table configured as described above, the number of bets, the result of the internal lottery process, the stopped state of the stopped reel R, and the operation timing of the stop button 13 are always maintained. Assuming that the same stop result can be obtained, within the allowed pull-in range, the symbol combination relating to the winning combination is established on the winning line L, and the symbol relating to the non-winning symbol The reel R can be stopped so that the combination is not established on the winning line L.

(4) Details of Symbol Determination Processing Details of symbol determination processing in the slot machine 1 will be described. The CPU 101 executes symbol determination processing after all of the reels R1 to R3 are stopped. FIG. 10 shows the structure of the winning combination table used in the symbol determination process in the slot machine 1. In the combination composition table, for each combination, a symbol combination corresponding to the combination and a payout to be awarded when the combination wins are defined. “ANY” indicates that any symbol may be used.

  The CPU 101 determines whether or not the symbol combination stopped on the winning line L matches any of the symbol combinations defined in the winning combination table. If the CPU 101 determines that it matches any of the symbol combinations defined in the symbol composition table, it determines that the symbol corresponding to the symbol combination has won and matches any symbol combination defined in the symbol composition table. If it is determined not to do so, it is determined that no winning combination has been won.

(5) Details of privilege grant processing Details of privilege grant processing in the slot machine 1 will be described. CPU101 performs privilege provision processing, after performing symbol determination processing. The privilege granting process is a process for granting a privilege according to the winning combination determined by the symbol determining process, and is realized using the winning combination table shown in FIG.

  When it is determined by the symbol determination process that the “replay” role, which is a re-playing role, has been won, the CPU 101 executes an automatic bet process by the privilege granting process (FIG. 5: Sa508 → Sa502). In the automatic bet process, a bet number equal to the bet number for starting the immediately preceding game is set in the bet counter stored in the RAM 105. If the CPU 101 determines that the “replay” role has not been won by the symbol determination process, and if it has been determined that the small role has been won by the symbol determination processing, the bonus grant process is used to deal with the winning small role The medal payment process is executed to pay out the number of medals indicated by the payout.

  The small role is a role associated with the payment of a medal as a dividend. In the slot machine 1, the “Cherry 1” role, the “Cherry 2” role, the “Watermelon 1” role, the “Watermelon 2” role, “Bell” role, “Control 1” role, “Control 2” role, “Control 3” role, “Control 4” role, “Control 5” role, “Control 6” role, and “Control 7” role , 2, 2, 3, 3, 9, 1, 1, 1, 1, 1, 1, and 1 are associated with each other. In the medal payment process, the CPU 101 adds a value corresponding to the payout corresponding to the winning combination determined to be won to the storage device. The CPU 101 pays out to the medal tray 40 game medals for which the number of credits in the storage device exceeds 50 by driving the medal payout device.

<5. AT Game> The slot machine 1 includes a normal game state that is a normal game state, and an AT state that is a game state that is more advantageous to the player than the normal game state. The slot machine 1 transitions the gaming state from the normal gaming state to the AT state when the predetermined start condition is satisfied, and changes the gaming state from the AT state to the normal game when the predetermined end condition is satisfied. Transition to the state. In this way, the slot machine 1 advances the game while switching the game state between the normal game state and the AT state.

The AT state in the slot machine 1 is to win a prize combination with the highest payout among a plurality of small figures with different payouts belonging to the lottery object when a specific lottery object is drawn as a result of the internal lottery process. This is a gaming state in which the player is notified of the pressing order of the stop buttons (operation order). At this time, when the stop button is operated in a pressing order other than the notified pressing order, the winning combination having the lowest payout is not awarded according to the timing of operating the stop button without winning the winning winning combination. Or win a small role. On the other hand, the normal gaming state is a state where the player is not notified of the push order for winning the above-mentioned small combination.

<5-1. Push Order Notification> A flow of processing related to the push order notification in the AT state of the slot machine 1 will be described with reference to FIG. When the internal lottery process is executed, the main control board 100A (CPU 101) determines whether or not the current gaming state is the AT state (Sa1101). When the CPU 101 determines that the gaming state is not the AT state, the CPU 101 ends the process as it is (Sa1101: NO). On the other hand, when the CPU 101 determines that the gaming state is the AT state (Sa1101: YES), the CPU 101 executes a process of specifying the notification content based on the result of the internal lottery process (Sa1102). Next, execution of notification according to the specified notification content is instructed to the display control board 100B via the data transmission circuit 106 (Sa1103). Although not shown, the display control board 100B (CPU 191) causes the liquid crystal display device 30 to output the specified notification content in accordance with an instruction relating to the execution of the notification received from the main control board 100A (CPU 101).

The process (Sa1102) for specifying the notification content is executed using the push order notification table shown in FIG. In the push order notification table, the correspondence between the lottery result by the internal lottery process and the notification content to be displayed on the liquid crystal display device 30 is defined. In the push order notification table, the lottery object 6, the notification content that prompts the user to operate the left stop button 13a as the first stop, the lottery subject 7, the notification content that prompts the user to operate the middle stop button 13b as the first stop, and the lottery subject 8 The notification content that prompts the user to operate the right stop button 13c as the first stop is associated with each other, and the other lottery objects are associated with not performing notification. In the process of specifying the notification content, the CPU 101 specifies the notification content to be output to the liquid crystal display device 30 based on the lottery result by the internal lottery process by referring to the push order notification table. As described above, when the gaming state is the AT state, the slot machine 1 notifies the player of the notification content corresponding to the result of the internal lottery process.

<5-2. Stop Control> The reel stop process in the slot machine 1 when the lottery target to be notified of the push order in the AT state is lottered as a result of the internal lottery process.

(1) Priority on the number of payouts The slot machine 1 executes a reel stop process so as to win as much as possible the winning combination determined by the internal lottery process. That is, when there is a symbol constituting the symbol combination related to the winning combination within the retractable range (within the range of the maximum amount of reel rotation for 4 symbols) from the time when the stop button 13 is operated. In this case, the symbol is drawn on the winning line L and stopped.

Hereinafter, the case where the lottery object 6 is lottery by the internal lottery process using the internal lottery table shown in FIG. 6 will be described as an example. In this state, the CPU 101 selects any one of the “Bell” role, the “Control 1” role, the “Control 2” role, the “Control 3” role, the “Control 4” role, and the “Control 5” role in which the winning is won. The reel stop process is executed so that the winning combination is won as much as possible.

[First Stop [Left] First Stop [Left] Operation at Correct Answer] When the left stop button 13a is operated as the first stop, the CPU 101 can be pulled in when the left stop button 13a is operated. Within the range, there is a “Bell” symbol that constitutes the “Bell” role that is the winning combination, and a “Watermelon” symbol that constitutes one of the “Control 1 to 4” roles that are other winning roles, or “Control” If there is no “plum” symbol that constitutes the “5” combination, a reel stop process for the left reel R1 is executed so that the “bell” symbol is stopped on the winning line L.

On the other hand, when the left stop button 13a is operated as the first stop, the CPU 101 has a “Bell” role (9 cards) that is a winning combination within a range that can be pulled in when the left stop button 13a is operated. “Bell” symbol that constitutes (dividend), and “watermelon” symbol or “control 5” symbol that constitutes one of the other “winning roles” (1-4 dividends) In the case where there is a “plum” symbol that constitutes a “single payout”, the left reel is set so that the “bell” symbol that constitutes the “bell” role with the highest dividend is stopped on the winning line L. The reel stop process for R1 is executed.

That is, when the left stop button 13a is operated in the first stop in the situation where the lottery object 6 is lottered by the internal lottery process, the CPU 101 must be “bell” regardless of the operation timing of the left stop button 13a. A reel stop process for the left reel R1 is executed so that the symbol is stopped on the winning line L.

When the “bell” symbol stops on the winning line L in the left reel R1, only the “bell” role is left as a possible winning combination. For this reason, the CPU 101 displays the “bell” symbol that constitutes the “bell” role in each of the middle reel R2 and the right reel R3, regardless of the order of operation and timing of the middle stop button 13b and the right stop button 13c. A reel stop process is performed on each of the middle reel R2 and the right reel R3 so as to stop on the winning line L.

In the slot machine 1, the “bell” symbols on each reel R are arranged at intervals of a maximum of four symbols. That is, when the left stop button 13a is operated as the first stop in the situation where the lottery object 6 is lottered by the internal lottery process, the stop button 13 can be operated regardless of the timing when the stop button 13 is operated. It is possible to execute a reel stop process for each reel R so as to stop the “bell” symbol existing within the retractable range at the time of operation. That is, when the left stop button 13a is operated as the first stop in the situation where the lottery object 6 is lottery by the internal lottery process, the “bell” role is won.

(2) Combination number priority [first stop [left] first stop [right] operation during correct answer] In the above-described situation, the CPU 101 operates the right stop button when the right stop button 13c is operated as the first stop. There is a “Plum” symbol that constitutes one of the “Control 3-5” roles as the winning combination within the range that can be pulled in when 13c is operated, and the “Bell” role as the other winning combination If there is no “Bell” symbol that constitutes the “Control 1” role, or “Cherry” symbol that constitutes the “Control 2” role, the “Plum” symbol is assigned to the winning line L A reel stop process for the right reel R3 is executed so as to stop the top.

On the other hand, when the right stop button 13c is operated as the first stop, the CPU 101 performs the “control 3-5” role that is the winning combination within the retractable range when the right stop button 13c is operated. There is a “Plum” symbol (contributing to the winning of three types of roles), and the “Bell” symbol that constitutes the “Bell” role that is another winning role (for winning one type of character) Contribution), “BAR” symbol (contributing to one type of winning) or “cherry” symbol (contributing to one type of winning) constituting “control 2” Even when it exists, the reel stop process for the right reel R3 is executed so that the “plum” symbols, which are the symbols constituting the most symbol combinations related to the winning combinations, are stopped on the winning line L.

That is, when the right stop button 13c is operated in the first stop in the situation where the lottery object 6 is lottered by the internal lottery process, the CPU 101 always sets “Plum” regardless of the operation timing of the right stop button 13c. The reel stop process for the right reel R3 is executed so that the symbols are stopped on the winning line L.

In the slot machine 1, the “plum” symbols on each reel R are arranged at intervals of a maximum of 4 symbols. That is, when the right stop button 13c is operated as the first stop in the situation where the lottery object 6 is lottered by the internal lottery process, the stop button 13 can be operated regardless of the timing when the stop button 13 is operated. It is possible to execute a reel stop process for each reel R so as to stop the “plum” symbols that exist within the retractable range at the time of operation.

When the “Plum” symbol is stopped on the winning line L on the right reel R3, only the “control 3-5” combination is left as a possible winning combination. For this reason, when the middle stop button 13b is operated in the second stop, the CPU 101 configures the “plum” that constitutes the “control 3” role within the retractable range at the time when the middle stop button 13b is operated. When there is a symbol, a “bell” symbol that constitutes a “control 4” role, or a “7” symbol that constitutes a “control 5” role, so that any symbol is stopped on the winning line L, A reel stop process is executed for the middle reel R2.

Next, even when the left stop button 13a is operated in the third stop, the CPU 101 determines that the right reel R3 and the middle of the symbols existing within the retractable range at the time when the left stop button 13a is operated. The reel stop process for the left reel R1 is executed so that the symbols constituting the winning combination that has the possibility of winning when the reel R2 stops are stopped on the winning line L.

In the slot machine 1, the “plum” symbols on each reel R are arranged at intervals of a maximum of 4 symbols. That is, when the right stop button 13c is operated as the first stop in the situation where the lottery object 6 is lottered by the internal lottery process, the right stop button is operated regardless of the timing when the right stop button 13c is operated. It is possible to execute the reel stop process for the right reel R3 so as to stop the “plum” symbol existing within the retractable range at the time point 13c is operated. That is, when the right stop button 13c is operated as the first stop in the situation where the lottery object 6 is drawn by the internal lottery process, the type of the stop button 13 in the second stop and the third stop and the operation timing are related. The “Bell” role is not won.

[First Stop [Left] First Stop [Middle] Operation During Correct Answer] Although detailed explanation is omitted, in the above-described situation, the CPU 101 operates the middle stop button 13b as the first stop. As in the case of the reel stop process when the right stop button 13c is operated as the first stop described above, the reel stop process is executed so as to win a winning combination other than the “bell” combination as much as possible. .

(3) Summary As described above, in the situation where the lottery object 6 is drawn by the internal lottery process, the slot machine 1 always wins the “Bell” role when the left stop button 13a is operated at the first stop. When the stop button 13 other than the left stop button 13a is operated in the first stop, the reel stop process is executed so that the “bell” combination is not always won. By the same mechanism, in the situation where the lottery object 7 is drawn by the internal lottery process, the middle stop button 13b is always operated when the middle stop button 13b is operated at the first stop, and the middle stop button at the first stop. When the stop button 13 other than 13b is operated, the reel stop process is executed so that the “bell” role is not always won, and in the situation where the lottery object 8 is drawn by the internal lottery process, the right at the first stop When the stop button 13c is operated, the “bell” role is always won, and when the stop button 13 other than the right stop button 13c is operated at the first stop, the “bell” role is not always won. The reel stop process is executed.

As described above, when the slot machine 1 obtains a specific result by the internal lottery process, the “bell” combination that cannot be reliably won in the normal gaming state is displayed in the push order notified in the AT state. By operating the stop button 13 as shown in FIG.

<5-3. Various state management during AT game> (1) Start of AT state The slot machine 1 starts the AT game by shifting the gaming state from the normal gaming state to the AT state when a predetermined condition is satisfied. Hereinafter, the flow of the process related to the AT lottery process as the process related to the start of the AT game in the slot machine 1 will be described with reference to FIG.

The CPU 101 determines whether or not a specific lottery object (hereinafter referred to as “specific lottery object”) has been drawn as a result of the internal lottery process (Sa1301). The specific lottery object in the slot machine 1 refers to the lottery objects 1 to 4, and the probability of being drawn by the internal lottery process compared to other lottery objects 5 to 9 (hereinafter referred to as “normal lottery object”). It is a relatively low lottery target. When the CPU 101 determines that the specific lottery object has not been drawn, the CPU 101 ends the process (Sa1301: NO).

On the other hand, when it is determined that the specific lottery object has been drawn (Sa1301: YES), the CPU 101 executes an AT lottery process (Sa1302). The AT lottery process is a process for determining whether an AT game is won or not by lottery.

FIG. 14 is an explanatory diagram for explaining an AT lottery table used for the AT lottery process. In the AT lottery table, a correspondence relationship between a lottery result obtained by the internal lottery process and a lottery value indicating a lottery probability related to the winning of the AT game is defined. More specifically, in the AT lottery process, the CPU 101 compares the random value acquired in the range of 0 to 65535 from a random number generator (not shown) with the lottery value corresponding to the lottery result in the internal lottery process, If the random value is smaller than the lottery value, it is determined that the AT game has been won.

After executing the AT lottery process, the CPU 101 determines whether or not the AT game is won by the AT lottery process (Sa1303). If the CPU 101 determines that the AT game is not won, the CPU 101 ends the process (Sa1303: NO). On the other hand, if the CPU 101 determines that the AT game is won (Sa1303: YES), the CPU 101 initializes the number of remaining AT games (Sa1304). Specifically, the CPU 101 sets 50 as an initial value in an AT game number counter indicating the number of remaining AT games stored in the RAM 105. Although illustration is omitted, at this time, the CPU 101 initializes the digest game number counter stored in the RAM 105 and indicating the number of games digested during the AT game to zero.

Next, the CPU 101 shifts the gaming state to the AT state (Sa1305). Specifically, the CPU 101 sets information indicating the AT state as the gaming state and stores it in the RAM 105. The slot machine 1 starts an AT game when the gaming state has shifted from the normal gaming state to the AT state.

Although illustration is omitted, at this time, the CPU 101 transmits a command for instructing to execute an effect indicating that the AT game has started to the display control board 100B via the data transmission circuit 106. . The display control board 100B (CPU 191) receives this command and causes the liquid crystal display device 30 to display an effect indicating that the AT game has started.

Further, the CPU 101 obtains the information related to the above-described AT game number counter indicating the number of remaining AT games and the digest game number counter indicating the number of games digested during the AT game, for each game in the AT game. At this timing, the data is transmitted to the display control board 100B via the data transmission circuit 106. Based on these pieces of information, the display control board 100B (CPU 191) causes the liquid crystal display device 30 to always display the number of remaining AT games and the number of games digested during the AT game during the AT game.

(2) Termination of AT State The slot machine 1 transitions the gaming state from the AT state to the normal gaming state upon completion of a predetermined condition, and terminates the AT game. Hereinafter, a flow of processing related to the end of the AT game in the slot machine 1 will be described with reference to FIG.

The process related to the end of the AT game in the slot machine 1 is a process executed after the process related to the notification of the pressing order in the AT state shown in FIG. The processes Sa1501 to Sa1503 are the same as the processes Sa1101 to Sa1103 in FIG.

The CPU 101 subtracts the number of remaining games of the AT game (Sa1504). Specifically, the CPU 101 subtracts 1 from the AT game number counter indicating the number of remaining AT games stored in the RAM 105. Although illustration is omitted, at this time, the CPU 101 increments the digest game number counter stored in the RAM 105 and indicating the number of games digested during the AT game by one.

Next, the CPU 101 determines whether or not the number of remaining AT games remains (Sa1505). Specifically, the CPU 101 determines whether or not the value of the AT game number counter is zero. If the CPU 101 determines that the number of remaining AT games remains (the value of the AT game number counter is not 0), the CPU 101 ends the processing (Sa1505: NO).

On the other hand, if the CPU 101 determines that the number of remaining AT games remains (Sa1505: YES), the CPU 101 shifts the gaming state from the AT state to the normal gaming state (Sa1506). The slot machine 1 ends the AT game when the gaming state shifts from the AT state to the normal gaming state.

As described above, in the slot machine 1, the AT game remaining game number is set at the start of the AT game, and the AT game remaining game number is subtracted every time one game is executed. When the number reaches 0, the AT game ends.

(3) Adding the number of games The slot machine 1 increases the number of remaining AT games when the predetermined condition is established during the AT game. Hereinafter, the flow of processing related to the addition of the number of remaining AT games in the slot machine 1 will be described with reference to FIG.

The CPU 101 determines whether a specific lottery object has been drawn as a result of the internal lottery process (Sa1601). As described above, the specific lottery object in the slot machine 1 refers to the lottery objects 1 to 4 and is compared with other lottery objects 5 to 9 (hereinafter referred to as “normal lottery object”) by an internal lottery process. It is a lottery object with a relatively low probability of being drawn. If the CPU 101 determines that the specific lottery object has not been drawn, the CPU 101 ends the processing as it is (Sa1601: NO).

On the other hand, if the CPU 101 determines that the specific lottery object has been drawn (Sa1601: YES), the CPU 101 executes an extra lottery process (Sa1602). The extra lottery process is a process of determining the number of remaining AT games to be increased by lottery.

FIG. 17 is an explanatory diagram for explaining the extra lottery table A used for the extra lottery process. In the extra lottery table A, the correspondence between the lottery result by the internal lottery process, the lottery value indicating the lottery probability of each extra game number, and the extra game number is defined. More specifically, in the extra lottery process, the CPU 101 compares the random value acquired in the range of 0 to 65535 from a random number generator (not shown) with the lottery value corresponding to the lottery result in the internal lottery process, Determine the number of extra games.

The lottery method for determining the number of additional games by comparing the random number value and the lottery value in the extra lottery process is the same as the lottery method in the internal lottery process described above, and will not be described. However, the extra lottery shown in FIG. When the lottery object 1 or 3 is drawn by the internal lottery process by the extra lottery process using the table A, 300 games, 200 games, 100 games, or 0 games are added to the number of remaining games of the AT game. If the lottery object 2 or 4 is selected by the internal lottery process, 50 games, 30 games, 20 games, 10 games, 5 games, or 0 games are determined as the number of additions to the number of remaining AT games. Is done.

The CPU 101 adds the number of games determined by the extra lottery process to the number of remaining games of the AT game (Sa1603). Specifically, the CPU 101 adds the number of games determined by the extra lottery process to the AT game number counter indicating the number of remaining AT games stored in the RAM 105.

As described above, the slot machine 1 adds the remaining number of games in the AT game when a predetermined condition is established during the AT game.

(4) Extra special zone The slot machine 1 compares the gaming state with the normal AT state when a predetermined condition is established in the AT game, and the remaining number of AT games in the extra lottery process described above. Is shifted to the specialization state, which is a gaming state in which is easily added.

FIG. 18 is an explanatory diagram for explaining a state transition lottery table used for a lottery process for determining whether or not to shift to a special state by adding a gaming state during an AT game.

In the state transition lottery table, a correspondence relationship between a lottery result obtained by the internal lottery process and a lottery value indicating a lottery probability related to the transition to the game state addition specialization state is defined. More specifically, in the lottery process, the CPU 101 compares the random value acquired from a random number generator (not shown) in the range of 0 to 65535 with the lottery value corresponding to the lottery result in the internal lottery process, When the random value is smaller than the lottery value, it is determined to add the gaming state and shift to the specialized state. When it is determined by the lottery process that the gaming state is added and the state is shifted to the specialized state, the CPU 101 sets information indicating the added special state as the gaming state and stores the information in the RAM 105. Since the flow of processing related to the addition of the number of remaining games of the AT game in the added special state in the slot machine 1 is the same as the content shown in FIG. 16, detailed description thereof is omitted.

FIG. 19 is an explanatory diagram for explaining the extra lottery table B used for the extra lottery process in the extra special state. In the extra lottery table B, as in the extra lottery table A shown in FIG. 17, the correspondence between the lottery result by the internal lottery process, the lottery value indicating the lottery probability of each extra game number, and the extra game number is defined. In the extra lottery process, the CPU 101 compares the random value acquired from a random number generator (not shown) in the range of 0 to 65535 with the lottery value corresponding to the lottery result in the internal lottery process, and adds the number of extra games. To decide.

The extra lottery table B is the same as the extra lottery table A for the lottery values 1 and 3 and the lottery subjects 2 and 4 and the number of extra games, but the lottery values corresponding to the lottery targets 5 to 9 And it is different from the extra lottery table A in that it includes the number of extra games. For this reason, in the extra lottery process using the extra lottery table B, even if the lottery objects 5 to 9 are lottery as a result of the internal lottery process, the number of extra games may be determined. Compared to the extra lottery process using the lottery table A, the number of remaining games of the AT game is easily added.

In the slot machine 1, the specialization state is completed in accordance with the consumption of the predetermined number of games. Specifically, the CPU 101 sets the specialization state in accordance with the addition special state counter that is set when the game state is added and shifted to the specialization state and is decremented by 1 for each game. And the gaming state is shifted to the AT state.

(5) Limit function The slot machine 1 is subject to whether or not the number of games remaining during the AT game has reached the condition that the number of games digested during the AT game has reached a predetermined 1500 games as the maximum number of AT games. A limit function for forcibly terminating the AT game is provided.

More specifically, the CPU 101 determines whether or not the digest game number counter has reached 1500 for each game in the AT game, and determines that the digest game number counter has reached 1500. Ends the AT game by resetting the AT game number counter to 0 and shifting the gaming state from the AT state to the normal gaming state.

Unlike the remaining number of AT games, the number of games consumed during the AT game is only subtracted. Therefore, due to the presence of the limit function, the total amount of medals to be paid out during a series of AT games is constant. It is guaranteed that the amount will not be exceeded.

(6) Special process for adding the number of games The slot machine 1 executes the above-described extra lottery process so as to avoid the activation of the above-described limit function. More specifically, when the slot machine 1 determines the number of additional games by the extra lottery process, the number of extra games determined by the extra lottery process is added to the remaining number of games of the current AT game. Even so, the number of additional games is determined so that the number of games digested during the AT game does not exceed the maximum number of digested AT games.

For example, in a situation where the number of remaining AT games is 163 and the number of games consumed during the AT game is 1278, the lottery target 3 that is the target for the specific lottery is drawn by internal lottery processing. As a result of executing the extra lottery process using the extra lottery table A, even if 200 is determined as the additional number of games, the additional number of games is re-determined as 58, and the remaining number of AT games is determined. to add.

This is because, if 200 as the number of added games determined first is added to the number of remaining games of the AT game as it is, the remaining games of the AT game will be executed even if the additional lottery process is not executed again during the AT game. The total of the number of games, the number of games digested during the AT game, and the number of additional games is 1641, and the number of games digested during the AT game will eventually reach 1500 games, the maximum number of digested AT games. This is to avoid reaching 1500 games, which is the maximum number of digested AT games in the future, by re-determining the number of additional games.

More specifically, the CPU 101 subtracts the AT game number counter and the digest game number counter from the maximum digest AT game number (1500) when the additional game number is determined by the extra lottery process. This is realized by redetermining the determined number of added games to a value smaller than the value.

As described above, the slot machine 1 has a limit function for limiting the total amount of medals to be paid out during a series of AT games so that the total amount does not exceed a certain amount. The lottery process is performed so as to avoid the end of the process. Thereby, it can be avoided in advance that the player feels disadvantageous because the AT game is forcibly ended.

<6. Modification> The above-described embodiment can be variously modified. Specific modifications are exemplified below. One or more aspects arbitrarily selected from the following examples can be appropriately combined as long as they do not contradict each other.

(1) Modification 1 In the above-described form, after determining the number of additional games through the additional lottery process, it is determined whether or not the number of games digested during the AT game reaches the maximum number of digested AT games. An aspect has been described in which, when it is determined that the maximum number of digested AT games has been reached, the determined additional number of games is redetermined. However, when determining the number of additional games through the extra lottery process, a range is set in advance so that the number of games digested during the AT game does not reach the maximum number of digested AT games. May be determined.

For example, as in the above-described example, in a situation where an AT game is in progress, the number of remaining AT games is 163, and the number of games consumed during the AT game is 1278, the lottery is subject to a specific lottery by internal lottery processing. When the lottery object 3 is selected, a value less than the value obtained by subtracting the AT game number counter and the digest game number counter from the maximum number of digested AT games (1500) is added, for example, in a range up to 50. You may make it perform addition lottery processing so that the number of games may be determined.

In order to achieve this, the lottery range for the number of extra games (in the above-described situation, the range of 0 to 300) determined by the extra lottery table is calculated from the maximum number of digested AT games when the extra lottery process is executed. Based on the value obtained by subtracting the game number counter and the digest game number counter, it may be set dynamically, or a plurality of types of addition lottery tables are prepared in advance, and the AT number is calculated from the maximum digest AT game number. Based on the value obtained by subtracting the game number counter and the digest game number counter, a lottery table having an appropriate range may be appropriately selected and used for the lottery process.

By executing the extra lottery process in this way, it is possible not only to determine the extra game number without executing wasteful processing, but also to determine the extra game number that has been determined, for example, in a normal situation Avoiding the determination of an unnatural number of additional games that are not determined (for example, the number of additional games of 58 as described above) can be realized with a simpler configuration.

(2) Modification 2 In each of the above-described forms, the number of games to be digested during an AT game is increased so as not to exceed the maximum number of digested AT games depending on whether the gaming state is an additional specialized state or not. The contents of the process for determining the number of games may be changed.

This is because, in the case where the additional special state is composed of a plurality of games (when the additional special state counter is set as a value of 2 or more when shifting to the additional special state), the additional special state This is to prevent the number of added games determined by each added lottery process from becoming unnatural because there is a high possibility that the added lottery process will be executed a plurality of times in a period during which is valid.

For example, as a result of the first extra lottery process in the extra special state, if the estimated number of games to be consumed during the AT game is changed from 1400 games to 1499 games, the second extra lottery process is executed. In such a case, it is impossible to determine the number of games to be added within the range where the number of games to be digested during the AT game is 1500 or less, so the first addition is made so as not to fall into such a situation. The lottery result is controlled from the lottery process.

More specifically, when the prospect of the number of games to be digested during the AT game is 1400, and when an additional special state is started in which the expected value of the number of times the extra lottery process is executed is four, Each extra lottery process is executed so that the expected value or the upper limit value of the number of extra games determined by each extra lottery process is 25. By controlling in this way, even when the extra lottery process is executed a plurality of times in the extra special state, the number of extra games determined by each extra lottery process is small, and a more natural extra game The number can be determined.

Further, the expected value or the upper limit value of the number of extra games determined by the extra lottery process based on the expected value at which the extra lottery process is executed as described above and the likelihood of the number of games to be digested during the AT game. Is not limited to the method of limiting the number, the number and timing of the extra lottery process executed in the extra special state at the start of the extra special state, a method of determining in advance at the time of transition to the extra special state, Furthermore, even by the method of predetermining the number of additional games determined by each additional lottery process, the number of additional games determined by each additional lottery process is small and more natural, as in the example described above. Can be determined.

(3) Modification 3 In each of the above-described forms, an additional lottery is performed so that the number of additional games equal to or greater than the maximum number of digested AT games (1500) minus the AT game number counter and the digested game number counter is not determined. The aspect which performs a process was demonstrated. Here, in addition to the above-described contents, a predetermined threshold value (for example, 1300) smaller than the maximum digested AT game number is set in advance, and the AT game number counter and the digested game number counter are set based on the predetermined threshold value (1300). An extra lottery process may be executed so that the number of extra games equal to or greater than the value obtained by subtracting is not determined.

As a result, the number of added games exceeds the value obtained by subtracting the AT game number counter and the digested game number counter from the maximum number of digested AT games (1500). The condition exceeding the value obtained by subtracting the game number counter and the digest game number counter is more easily established, so that the limitation of the number of additional games by the extra lottery process can be executed in stages. become. In other words, the number of extra games determined by the extra lottery process will not be suddenly restricted to a smaller number than usual, but will gradually be restricted, so that the change will be realized in a more natural manner. become.

Furthermore, when the predetermined threshold value (1300) is less than or equal to 0, which is obtained by subtracting the AT game number counter and the digest game number counter, the lottery process is added on the basis of the predetermined threshold value (1300). It may be possible to invalidate the determination.

(4) Modification 4 In each of the above embodiments, at least the AT game number counter is managed only by the main board 100A (CPU 101), but the main board 100A (CPU 101) and the display control board 100B are explained. You may comprise so that an AT game number counter may be managed with each (CPU191).

In this configuration, the CPU 101 adds the number of added games determined by the additional lottery process to the AT game number counter managed by the main board 100A (CPU 101), and information on the number of added games determined by the additional lottery process. Is transmitted to the display control board 100B via the data transmission circuit 106. The display control board 100B (CPU 191) adds an additional game number to the AT game number counter managed by the display control board 100B (CPU 191) based on the information received from the main board 100A (CPU 101). If the number exceeds the maximum digested AT game number (1500) or a value obtained by subtracting the AT game number counter and the digested game number counter from the predetermined threshold (1300), Change the number of added games to a different value (the number of added games does not exceed the maximum number of digested AT games or a value obtained by subtracting the AT game number counter and the digested game number counter from a predetermined threshold) The number of added games is added to the number counter.

Then, the display control board 100B displays the number of remaining AT games on the liquid crystal display device 30 based on the AT game number counter managed by the display control board 100B (CPU 191). In this case, the AT game number counter managed by the main board 100A (CPU 101) and the AT game number counter managed by the display control board 100B (CPU 191) are managed as different values. (CPU 101)
Since the value of the AT game number counter managed in the above is not displayed on the liquid crystal display device 30, the player cannot recognize the mismatch between the two values.

Accordingly, in the extra lottery process, the display control is performed not on the main board 100A (CPU 101) but on the main board 100A (CPU 101) to determine the extra game number so that the number of games to be digested during the AT game does not exceed the maximum digest game number or a predetermined threshold. Since the processing can be executed by the substrate 100B (CPU 191), the processing burden on the main substrate 100A (CPU 101) can be reduced.

(5) Modified Example 5 In each of the above-described embodiments, the aspect in which the maximum number of digested AT games, the predetermined threshold value, the AT game number counter, and the digested game number counter are set or managed in units of the number of games has been described. However, at least one of these may be set or managed by other units.

Specifically, for example, 3000 is set as the maximum payout number instead of the maximum number of AT games, and the payout is the cumulative number of medals paid out during the AT game instead of the digest game number counter. The medal counter may be managed so that the AT game is forcibly terminated when the payout medal counter reaches 3000 as the maximum payout number.

In addition to the above, the AT payout number is managed in place of the AT game number counter and the additional payout number is managed in place of the additional game number, and the additional payout number determined by the extra lottery process is added to the AT payout number. You may do it. In this case, the AT payout number is managed as the cumulative number of medals paid out during the AT game. As described above, the unit of each counter and each threshold may be the number of medals instead of the number of games, or may be configured to be set or managed by other units.
