Abstract

PROBLEM TO BE SOLVED: To provide a game machine preventing players from discriminating whether or not a setup is changed.

SOLUTION: The game machine employs a same scenario table 60 after setup change and after termination of a pseudo bonus mode. The scenario table 60 is regulated to progress a game in a high probability state where a probability of winning a pseudo bonus transfer lottery is high, until a prescribed-period game is executed after the termination of the pseudo bonus mode. Lottery means 64 executes a forced low-probability lottery when the setup is changed. When a player wins in the forced low-probability lottery, probability lowering means 66 forcibly changes the game state for a prescribed period after the setup change, to a low probability state where a probability of winning the pseudo bonus transfer lottery is low.

Description

  The present invention relates to a gaming machine such as a slot machine installed in a game hall such as a pachinko parlor.

  2. Description of the Related Art Slot machines that play (bet) game media are widely known (see Patent Documents 1 to 3 below). In the slot machine, the number of games is counted by the number-of-games counter, and according to the counted number of games, a high probability state with a high probability of being advantageous to the player and a low probability state with a low probability of being advantageous to the player are obtained. Switching.

  The relationship between the number of games and the high probability state or low probability state is defined by an LUT (Look Up Table) called a scenario table. In the scenario table, for example, a plurality of game sections are set based on the number of games since the game number counter is reset, such as 0 to 25 games as the first game section, and 26 to 50 games as the second game section, Each game section is associated with whether the game section is in a high probability state or a low probability state.

  In the slot machine, the game number counter is reset when the setting of the slot machine is changed and at the end of the advantageous mode that is more advantageous to the player than the normal mode. That is, the game number counter counts the number of games without distinguishing whether the number of games has been changed since the setting was changed or the number of games since the advantageous mode ended. As described above, the gaming state (high probability state or low probability state) is determined based on the number of games counted by the game number counter. For this reason, even if the setting is changed and the advantageous mode is ended, the subsequent gaming state follows a common process.

  In the slot machine, the scenario table is designed so that the first game section is in a high probability state. By doing so, a high probability state is obtained immediately after the end of the advantageous mode, and the interest regarding the game can be maintained even if the advantageous mode ends. In other words, since the player plays a game for the purpose of playing in the advantageous mode, the interest related to the game decreases when the advantageous mode ends. Can be prevented.

  However, the conventional slot machine has a problem that it can be inferred from the gaming state whether or not the setting has been changed. That is, even after the setting is changed, the high probability state is obtained just after the advantageous mode ends, so the high probability state even though the number of games after the previous advantageous mode ends does not correspond to the first game section. In such a case, it is assumed that there is a high possibility that the setting has been changed.

  In order to prevent such a problem, a scenario table used after the setting change may be provided separately from the scenario table used after the advantageous mode ends. However, in this case, the number of scenario tables increases, causing a problem that memory is insufficient.

  The present invention has been made in view of the above background, and a gaming machine in which it is impossible to infer whether or not a setting change has been made using a common scenario table after the setting change and after the advantageous mode ends. It is intended to provide.

  In order to achieve the above object, the gaming machine according to the present invention is a scenario table in which it is specified whether a game progresses in a high probability state where the probability that the player is advantageous is high or a low probability state where the probability is low. And determining whether the game proceeds in the high probability state or the low probability state using the scenario table when a predetermined condition is satisfied, and after changing the setting to change the setting of the gaming machine In the gaming machine that determines whether the game progresses in the high probability state or the low probability state using the same scenario table as the scenario table used when the predetermined condition is satisfied, the probability is lowered. Probability reduction means is provided, wherein the probability reduction means lowers the probability from when the setting change is made until a predetermined period elapses.

  The scenario table used when the predetermined condition is satisfied is preferably a scenario table used after the end of the advantageous mode that is more advantageous to the player than the normal mode.

  It is preferable that the probability reducing means performs a lottery when the setting is changed, and reduces the probability when the lottery is won.

  In the present invention, since the probability reducing means for reducing the probability that the player is advantageous is provided, and the probability reducing means reduces the probability until a predetermined period elapses after the setting is changed. Even when a common scenario table is used after the setting change and after the end of the advantageous mode, it is possible to prevent a problem that it is estimated whether or not the setting has been changed.

It is the flowchart which showed the process which sets the predetermined period after a setting change to a low probability state.

  As shown in FIG. 1, the slot machine (game machine) 10 includes a storage box 11 and a front door 12. The storage box 11 stores a reel unit in which first to third reels 20a to 20c, which will be described later, are unitized, and a hopper device that pays out medals to the medal tray 28 via a payout opening 27, which will be described later. Yes. The front door 12 is divided into an upper door 12a and a lower door 12b. The upper door 12a and the lower door 12b are pivotally attached to the storage box 11 and supported so as to be freely opened and closed.

  The upper door 12a is provided with a liquid crystal display 13, a speaker 14, and a display window 16. The liquid crystal display 13 displays various effect images. The speaker 14 outputs various effect sounds. The slot machine 10 produces a game by controlling the liquid crystal display 13 and the speaker 14.

  In the back of the display window 16, a rotatable first reel 20a, second reel 20b, and third reel 20c are provided. Plural kinds of symbols are arranged on the outer peripheral surfaces of the reels 20a to 20c, and three symbols per reel are displayed through the display window 16 when the reels 20a to 20c are stopped. Then, in the slot machine 10, it is notified whether or not the winning combination has been won by the combination of symbols displayed when the reels 20a to 20c are stopped.

  The winning combination determined in the winning combination lottery is roughly divided into three types: replay, small role, and bonus. When the replay wins, the next game can be performed without inserting a new medal, and when the small role wins, the hopper device Is activated and the number of medals corresponding to the type of the winning combination is paid out to the medal tray 28, and when the bonus is won, the game in the bonus state is executed from the next game. Note that if the small role cannot be won in the game of the time of winning the winning combination lottery, the right to win will be lost and so-called losing. The replay is designed not to be missed (the arrangement of symbols and the contents of stop control are determined), and can be won in the game of the time of winning the winning combination lottery. Unlike bonuses and replays, bonuses are carried over to the next and subsequent games even if the bonuses cannot be won in the game of the winning lottery.

  The slot machine 10 is provided with a batting order in which a correct answer and an illegal answer are simultaneously won as the winning mode of the small role. When the batting order is won, the operation order of the stop buttons 26a to 26c (batting order) When the stop buttons 26a to 26c are operated in the preset correct answer order, the reels 20a to 20c are controlled so that the correct combination is preferentially won, and the correct answer order is set in advance. When the stop buttons 26a to 26c are operated, stop control of the reels 20a to 20c is performed so that the illegal answering is preferentially won.

  Note that when the correct answerer or the incorrect answerer wins, the number of medals corresponding to the type of the winning combination is paid out, but in this embodiment, the number of medals paid out when the correct answerer wins is determined as an incorrect answer. It is set more than the number of medals to be paid out when the winning combination is won. Moreover, in this embodiment, the normal press which is a batting order generally performed by a normal player (the batting order in which the stop button 26a, the stop button 26b, and the stop button 26c are operated in this order, that is, the batting order in which the stop buttons are operated in order from the left) Is set as an incorrect answering order, and the ordering and the ordering push (the two hitting orders are collectively left 1st. Hitting order (left The batting order other than the first batting order) is set as the correct batting order. In this embodiment, as will be described later, in the pseudo general mode, even if the batting order combination is won, no notification effect (batting order notification) for notifying the correct batting order is performed, and in the pseudo bonus mode (advantage mode), the batting order combination is won. Then, the batting order notification is performed. Further, in the present embodiment, although the batting order notification is not performed, the left 1st. If a game is played in a batting order other than the batting order, a predetermined penalty is imposed on the player (for example, a pseudo bonus transfer lottery described later is not performed until a predetermined number of games are performed) The player is left 1st. The winning combination of the batting order due to the batting order other than the batting order is prevented.

  With this configuration, in the pseudo general mode in which the correct answer order is not notified, the left 1st. The game is played in the batting order, that is, the incorrect answering order, and only illegal answering can be won. On the other hand, in the pseudo bonus mode in which the correct batting order is notified, it is not necessary to avoid the penalty, and the correct combination can be won by playing the game in the correct batting order according to the notification. As a result, in the pseudo bonus mode, more medals can be obtained compared to the pseudo general mode in which only the illegal answering can be won (the pseudo bonus mode is more advantageous to the player than the pseudo general mode). Game mode).

  Below the display window 16, a 7-segment display 21 is provided. As will be described later, the display 21 displays a numerical value corresponding to the currently selected setting when changing the setting value or referring to the setting value.

  The lower door 12b has a medal slot 22 for inserting medals, a bet button 23 that is operated when betting credited medals, a start lever 24 that is operated when starting a game, and a rotating reel. Stop buttons 26a to 26c for stopping, a payout port 27 for paying out medals, and a medal tray 28 for receiving medals paid out from the payout port 27 are provided.

  In the slot machine 10, the operation of the start lever 24 is activated by inserting a medal into the medal insertion slot 22 or betting a credited medal by operating the bet button 23, and the activated start lever 24 is activated. When is operated, the game is started. When the game is started, the reels 20a to 20c start to rotate, and when the rotation speed of the reels 20a to 20c reaches a certain speed, the operation of the stop buttons 26a to 26c is activated, and the activated stop buttons 26a to 26c are activated. By operating 26c, the reels 20a to 20c corresponding to the operated stop buttons 26a to 26c can be stopped. Then, when all the reels 20a to 20c are stopped, if the symbol combination corresponding to the winning combination determined in the winning combination lottery is displayed, the winning combination is won.

  A cylinder 29 is provided on the front side of the lower door 12b. When a dedicated door key is inserted into the cylinder 29 and rotated, the locking of the lower door 12b is released. Thereby, the inside of the slot machine 10 can be opened by rotating the lower door 12b. Further, when the engagement between the slot machine 10 and the upper door 12a is released with the lower door 12b being rotated, the upper door 12a can be opened.

  As shown in FIG. 2, the inside of the slot machine 10 is partitioned into upper and lower parts, and a power supply box 30 is provided at the lower part thereof. The power supply box 30 is used not only for power supply of the slot machine 10 but also for setting change described later.

  As shown in FIG. 3, the power supply box 30 is formed in a box shape. On the front face of the power supply box 30, a setting key switch 30a for switching whether or not to change the setting, a power switch 30b for switching on / off the power supply, and any of settings 1 to 6 to be described later are selected. A setting change button 30c is provided.

  When changing the setting, the lower door 12b is opened and the setting change key 31 is inserted into the setting key switch 30a. Then, the setting change key 31 is turned to the ON position to turn on the setting key switch 30a. In this state, the power switch 30b is turned on. As a result, the slot machine 10 shifts from the state where the game is played to the state where the setting is changed. The slot machine 10 is provided with six stages of settings 1 to 6, and in the state of changing the setting, one of these six settings is selected by operating the setting change button 30c, and the start lever By operating 24, the setting can be changed to the setting selected at this time.

  In setting 1, the payout rate (ratio between the number of medals inserted into the game and the number of medals paid out as a result of the game) is the lowest, and payout in the order of setting 1 → setting 2 → setting 3 → setting 4 → setting 5 → setting 6 The rate is set to be high. That is, the game is played in a state (high setting) that is more advantageous to the player as it goes to the setting 6. In this way, in order to vary the payout rate for each setting, the slot machine 10 switches the winning combination lottery table used in the winning combination lottery described later according to the setting. Then, after changing the setting as described above, the setting key switch 30a is turned off to complete the change of the setting value, and the state returns from the state where the setting is changed to the state where the game is performed. These setting values are associated with scenarios (scenario A to scenario D) described later, and the probability of selecting a scenario that easily shifts to the pseudo bonus mode described later increases from setting 1 to setting 6. (See FIG. 6).

  In addition to the bonus state described above, the slot machine 10 plays in three game states: a normal state in which no bonus is won and a bonus internal state in which the bonus is won but not won. Is called. In the slot machine 10, by setting the bonus to be easy to win and difficult to win, almost all games are played in the bonus internal state.

  Specifically, for example, in the normal state, the bonus winning probability is set higher than that of replay or small role (making the bonus easier to win), and the bonus is always set to win simultaneously with replay or small role, Due to the winning priority, in the game where the bonus is won, it is difficult to win the bonus because the replay or small role wins preferentially. In addition, in the game after the time when the bonus is won, that is, in the bonus internal state, the winning probability of replay is set higher than the normal state (for example, replay is won in almost all games, etc.) In addition, it is difficult for the replay to win a bonus by preferentially winning.

  As described above, in the slot machine 10, almost all games are performed in the bonus internal state, so it is important to improve the gameability of the bonus internal state in order to increase the interest of the player. For this reason, in the slot machine 10, a plurality of game modes (in the present embodiment, the above-described pseudo general mode and pseudo bonus mode) are performed by switching the state of the effect by the sub control board 42 described later during the bonus internal state. It is expressed.

  As shown in FIG. 4, in the slot machine 10, by controlling each part of the slot machine 10, by controlling the main control board 40 that controls the execution and progress of the game, the liquid crystal display 13 and the speaker 14, A sub-control board 42 that controls the execution and progress of the performance is provided. The main control board 40 and the sub control board 42 are electrically connected, and various information such as information indicating a game state can be transmitted from the main control board 40 to the sub control board 42. Information cannot be transmitted from the board 42 to the main control board 40 (communication of information is one-way from the main control board 40 to the sub-control board 42).

  A reel drive controller 44 is connected to the main control board 40. The reel drive controller 44 controls the rotation of the reels 20a to 20c under the control of the main control board 40. The main control board 40 starts the rotation of the reels 20a to 20c when the activated start lever 24 is operated (that is, the game starts), and the activated stop buttons 26a to 26c are operated. Then, stop control of the reel corresponding to the operated stop button is performed. In the stop control, known pull-in control and kick-off control are performed.

  In addition, when the winning combination is won, the reel drive controller 44 performs stop control of the reels 20a to 20c so that the correct combination wins preferentially when each stop button 26a to 26c is operated in the correct answer order. When the stop buttons 26a to 26c are operated in the incorrect answering order, the reels 20a to 20c are controlled to stop so that the incorrect answering is preferentially won.

  The main control board 40 is provided with a winning combination determining unit 50 and a setting changing unit 52. The winning combination determining means 50 performs a winning combination lottery with the start of the game, and determines any of a plurality of types of winning combinations or a loss. In the winning combination lottery, a random number generated by a random number generator (not shown) is checked against the winning combination lottery table using a winning combination lottery table in which random numbers are assigned to each winning combination and loser. Which winning combination (or losing) is determined is determined. In the present embodiment, six types of winning combination lottery tables having different winning probabilities (number of random numbers assigned to each winning combination) are provided so as to correspond to the settings 1 to 6. It has been. Then, the winning combination determining means 50 executes the winning combination lottery using the winning combination lottery table corresponding to the current setting.

  The setting change unit 52 operates in accordance with the transition to a state where the setting is changed. The setting changing means 52 is provided with a memory (not shown) that stores the current setting. The setting changing means 52 displays a numerical value corresponding to the current setting on the display 21 along with the operation, and sets the setting. Each time the change button 30c is operated, the numerical value to be displayed is switched in the order of “... 1 → 2 → 3 → 4 → 5 → 6 → 1. Then, when the start lever 24 is operated, the setting change unit 52 stores the setting corresponding to the numerical value displayed at this time in the memory (rewrites the memory). The setting change means 52 notifies the sub control board 42 that the setting has been changed.

  The slot machine 10 is connected to an external device (not shown). For example, the external device is arranged above the slot machine 10 and displays a game history such as the number of times of transition to the pseudo bonus mode and the number of games since the previous pseudo bonus mode has ended. Thereby, the player can know the number of games since the end of the previous pseudo bonus mode, the number of occurrences of the pseudo bonus mode, and the like by confirming the display on the external device.

  Information displayed on the external device is transmitted from the main control board 40 to the external device. However, the information displayed on the external device is information related to the game mode expressed by the sub control board 42, and the sub control board 42 cannot transmit information to the main control board 40 as described above. For this reason, the main control board 40 presumes what game mode the sub-control board 42 expresses according to the hit order of the stop buttons 26a to 26c. That is, in the slot machine 10, the games are played in the correct hit order in the pseudo bonus mode (the correct hit order is notified in the pseudo bonus mode, and it is advantageous for the player to operate the correct hit order. Play games). In addition, in the slot machine 10, the game is played in the incorrect general batting order (left 1st. Batting order) in the pseudo general mode (the correct batting order is not notified in the pseudo general mode, and the left 1st. Batting order is not reported in the correct general batting order). Playing games in any other order will result in a penalty for the player, so the player will play in the wrong order.) For this reason, the main control board 40 estimates that the game is in the pseudo bonus mode while the game is played in the correct answer hit order, and estimates that the game is in the pseudo general mode while the game is played in the incorrect answer hit order.

  The sub-control board 42 is provided with effect data storage means 54, game number counter 56, effect control means 58, scenario table 60, scenario lottery table 62, lottery means 64 (probability reduction means), and probability reduction means 66. .

  The effect data storage means 54 stores image data for displaying the effect image from the liquid crystal display 13 and effect sound data for outputting the effect sound from the speaker 14. The sub-control board 42 reads out the image data and the effect sound data from the effect data storage means 54, thereby driving the liquid crystal display 13 to display the effect image and driving the speaker 14 to output the effect sound. To execute the game.

  The game number counter 56 is provided for counting the number of games and is controlled by the sub-control board 42. Each time the sub-control board 42 receives a notification from the main control board 40 that the game has started (the activated start lever 24 is operated), the sub-control board 42 increments the count value by “1” and changes the setting from the setting change means 52. The count value is reset when a notification that the operation has been performed is received and when a pseudo bonus mode to be described later is completed.

  The effect control means 58 expresses a plurality of game modes by switching the state of the effect. As described above, the game modes expressed by the effect control means 58 are roughly divided into a pseudo general mode and a pseudo bonus mode. The pseudo general mode is a game mode in which the batting order notification for notifying the correct batting order is not performed even if the batting order combination is won, and the left 1st. Since the game is played in the batting order, only illegal solvers can win. On the other hand, the pseudo bonus mode is a game mode in which a batting order notification is performed when the batting order combination is won, and the correct combination can be awarded when the stop buttons 26a to 26c are operated according to the notification. Is more advantageous for the player.

  From the pseudo general mode to the pseudo bonus mode, a transition is made when the pseudo bonus transition lottery is won during the pseudo general mode. In addition, when a predetermined end condition (for example, when a predetermined number of games are played or a predetermined number of medals are paid out) is satisfied during the pseudo bonus mode, the pseudo general mode is entered. Return.

  The pseudo bonus transition lottery is executed when a predetermined condition is satisfied (for example, when a predetermined winning combination is won in the winning combination lottery), and it is determined whether or not to shift to the pseudo bonus mode. In the pseudo bonus transition lottery, it is determined whether to shift to the pseudo bonus mode by using either a high-precision table with a high winning probability or a low-accuracy table with a low winning probability. The In the high accuracy table, the winning probability of the pseudo bonus transfer lottery is set to 70%, for example. In the low probability table, the winning probability of the pseudo bonus transfer lottery is set to 30%, for example. The production control means 58 differs in the production mode (production image displayed on the liquid crystal display 13 or production sound output from the speaker) depending on whether the high accuracy table is used or the low accuracy table is used. For example, when using a high-precision table, an effect mode is provided that increases the expectation for shifting to the pseudo bonus mode, and when using a low-accuracy table, an effect mode with a lower expectation than when using a high-precision table is used. For this reason, the player can know whether the high accuracy table is used or the low accuracy table is used depending on the mode of production.

  The production control means 58 determines with reference to the scenario table 60 whether to use the high-precision table or the low-precision table to perform the pseudo bonus transfer lottery.

  As shown in FIG. 5, the scenario table 60 includes the first to fourth game sections divided based on the count value of the game number counter 56 (that is, the number of games from the setting change or the end of the pseudo bonus mode). Is associated with either a high probability state (a state in which a pseudo-bonus transition lottery is performed using a high-accuracy table) or a low-probability state (a state in which a pseudo-bonus transition lottery is performed using a low-accuracy table). is there.

  In the first game section, the count value of the game number counter 56 is “0” to “25”, that is, a period from when the count value of the game number counter 56 is reset to 25 games (0 to 25 games Period). Similarly, in the second game section, the count value of the game number counter 56 is “26” to “50”, that is, a period from the end of the first game section to 25 games (26 to 50 games). Period). Further, the third game section has a count value of the game number counter 56 from “56” to “75”, that is, a period from the end of the second game section until 25 games have elapsed (a period of 51 to 75 games). ). Furthermore, in the fourth game section, the count value of the game number counter 56 is “76” to “100”, that is, a period from the end of the third game section to 25 games (period of 76 to 100 games). ).

  As a scenario in which a series of flows from the first to the fourth game section (transition between a high probability state and a low probability state) are grouped in this way, in this embodiment, four scenarios of scenario A to scenario D are I have prepared it.

  In scenario A, a high probability state is associated with the first game section. Similarly, a low probability state is associated with the second game section, a low probability state is associated with the third game section, and a low probability state is associated with the fourth game section. For this reason, in the scenario A, the game proceeds with a high probability of winning the pseudo bonus transition lottery in the first game section (that is, the period of 0 to 25 games), and the second game section to the fourth game section (that is, the game period) In the period of 26 to 100 games), the game proceeds with a low probability of winning the pseudo bonus transition lottery.

  Similarly, in the scenario B, a high probability state, a high probability state, a low probability state, and a low probability state are associated in order from the first game section. In this scenario B, since the high probability state is associated with the first game section and the second game section, the probability is higher than the scenario A in which the high probability state is defined only for the first game section. This is a scenario in which the number of games played in the state is large. For this reason, scenario B is a more advantageous scenario for the player than scenario A.

  In the scenario C, a high probability state, a low probability state, a high probability state, and a low probability state are associated in order from the first game section. In this scenario C, since the high probability state is associated with the first game section and the third game section, the scenario C is a more advantageous scenario for the player than the scenario A, like the scenario B. In addition, in scenario C, there are two sections in which high probability states are associated, as in scenario B. For this reason, scenario C and scenario B have the same number of games played in a high probability state, and there is no difference between advantages and disadvantages.

  In the scenario D, a high probability state, a high probability state, a low probability state, and a high probability state are associated in order from the first game section. As described above, in the scenario D, since the high probability state is associated with three sections of the first game section, the second game section, and the fourth game section, the high probability state is one section or two sections. This scenario is more advantageous than scenario A to scenario C.

  In addition, the effect control means 58 determines which scenario from the scenario A to the scenario D the game proceeds by the scenario lottery executed when the setting is changed and when the pseudo bonus mode is ended. To do. In the scenario lottery, any one of scenario A to scenario D is determined based on the scenario lottery table 62.

  As shown in FIG. 6, the scenario lottery table 62 is such that the selection rate of scenario A to scenario D (probability that any of scenario A to scenario D is selected by scenario lottery) becomes a value corresponding to the set value. It is stipulated in. In the scenario lottery table 62, the selection rate of the scenario A that is disadvantageous to the player in the order of setting 1 → setting 2 → setting 3 → setting 4 → setting 5 → setting 6 (that is, the setting that is advantageous to the player). On the other hand, the selection rate of scenario D advantageous to the player is increased.

  As described above, when the pseudo bonus mode is ended, the effect control means 58 executes the scenario lottery based on the scenario lottery table 62 and determines one of the scenarios, and based on the scenario table 60 (the scenario table 60 is changed to the scenario table 60). Use) to advance the game from the first game segment. As described above, in the scenario table 60, the first game section is set to a high probability state in all scenarios regardless of the type of scenario (see FIG. 5). Even if it is determined to be executed, after the pseudo bonus mode is ended (after the count value of the game number counter 56 is reset), the pseudo bonus transition lottery is always executed using the high-accuracy table (the game is always in a high probability state). Progress). In this way, even when the pseudo bonus mode is ended, the player can be expected to play the game again in the pseudo bonus mode, so that the player ends the game when the pseudo bonus mode ends. You can prevent problems.

  On the other hand, the effect control means 58 advances the game based on the same scenario table 60 (using the scenario table 60) as when the pseudo bonus mode is ended even when the setting is changed. For this reason, as after the end of the pseudo bonus mode, after the setting is changed (after the count value of the game number counter 56 is reset), the pseudo bonus transition lottery is always executed using the high accuracy table (always in the high probability state). It is determined whether or not the game proceeds to the pseudo bonus mode. As described above, even when the setting is changed, the same scenario table 60 as that when the pseudo bonus mode is ended is used, so that different scenarios are obtained when the setting is changed and when the pseudo bonus mode is ended. Compared with the case where the table 60 is used, it is possible to reduce the design effort of the scenario table 60 and also reduce the burden on the memory storing the scenario table 60.

  However, if the same scenario table 60 is used after the setting change and after the pseudo bonus mode ends, there is a problem that it is determined whether or not the setting change has been performed. Specifically, for example, in the case of a high probability state despite the 60th game since the end of the previous pseudo bonus mode, it is presumed that there is a high possibility that the setting has been changed. In other words, there are two cases, a case where the setting is changed and a case where scenario C is selected (see FIG. 5). There are cases, but the probability of being the latter case is 1/4 (one of four scenarios), so it is assumed that the former, that is, the probability that the setting has been changed is high. End up. In order to prevent such a problem, the sub-control board 42 is provided with a lottery means 64 and a probability reduction means 66 (see FIG. 4).

  The lottery means 64 executes the forced low probability lottery using the forced low probability lottery table 68 and determines whether or not to change the predetermined period to the low probability state forcibly. In the following, an example in which the predetermined period is a period from when the count value of the game number counter 56 is reset until the count value exceeds “25”, that is, the predetermined period and the first game period coincide with each other. An example will be described.

  As shown in FIG. 7, the forced low probability lottery table 68 defines the probability of determining whether or not to change to the low probability state. For example, the probability of determining to change to the low probability state is defined as 2/3, and the probability of determining not to change to the low probability state (that is, to remain in the high probability state) is 1/3. It is prescribed.

  The probability reducing means 66 is operated by the sub control board 42. The probability lowering means 66 drives the lottery means 64 in accordance with the operation to execute the forced low probability lottery. Then, when it is determined to enter the low probability state by the forced low probability lottery, the predetermined period (the first game section in the present embodiment) is forcibly set to the low probability state.

  Next, processing for setting the predetermined period after the setting change to the low probability state will be described with reference to the flowchart shown in FIG.

  When the setting change is made, the sub control board 42 writes a flag indicating that the setting change has been made in a memory (not shown). Then, the sub-control board 42 determines whether or not the setting has been changed by referring to the memory and confirming the presence or absence of the flag when performing the pseudo bonus transition lottery. In this determination, the sub control board 42 determines that the setting has been changed when the flag is written in the memory, and determines that the setting has not been changed when the flag is not written in the memory. Then, when it is determined that the setting has been changed (that is, when a flag is written in the memory), the sub control board 42 operates the probability reducing unit 66.

  The probability lowering unit 66 drives the lottery unit 64 to execute the forced low probability lottery when operated. After the forced low probability lottery is performed in this manner, the sub control board 42 can change the game in the first game section with a probability corresponding to the result of the forced low probability lottery (that is, the low probability state). If it is determined, a low probability table is used, and if it is determined not to change to a low probability state, a pseudo bonus transfer lottery is performed (using a high probability table). Further, when the forced low probability lottery is performed, the sub control board 42 erases the flag written in the memory regardless of the result of the forced low probability lottery. That is, in this embodiment, if the setting change is performed once, the forced low probability lottery is performed once, and if it is decided to change to the low probability state by the forced low probability lottery, all games in the first game section are low. Set to a probability state.

  As a specific method for forcibly setting the predetermined period to the low probability state, the effect control means 58 is set to a state in which the pseudo bonus transition lottery is performed using the low probability table regardless of the scenario table 60 for the predetermined period. The contents of the scenario table 60 may be rewritten for a predetermined period. When rewriting the contents of the scenario table 60, the contents regarding all scenarios may be rewritten, or the contents may be rewritten only for the currently selected scenario.

  As described above, according to the slot machine 10, the predetermined period after the setting change is in the low probability state, and the predetermined period after the setting change is not necessarily in the high probability state. It is possible to prevent the problem of whether or not it is estimated.

  In the above embodiment, a compulsory low probability lottery is performed once with one setting change, and when the compulsory low probability lottery is won, all the games in the first game section are set to a low probability state. However, the present invention is not limited to this example. For example, when the setting is changed, it is decided to perform a forced low probability lottery for each of all the games in the first game section, determine whether to set the low probability state, and set the low probability state. Only a single game may be played in a low probability state. That is, when 25 games are included in the first game section as in the above embodiment, 25 forced low probabilities are used to determine whether or not each of these 25 games is in a low probability state. A lottery may be performed and the game determined to be set to the low probability state may be performed in the low probability state. Of course, the first game section is further divided into a plurality of sections, and it is determined whether or not each section has a low probability state. When the low probability state is set, the game is played in the low probability state only for the determined section. You may go. Specifically, for example, the first game section is divided every five games (the first game section is divided into five sections), and five forced low-probability lotteries are performed, It may be determined whether or not to be in a low probability state, and the game may be performed in the low probability state only for the section determined to be set to the low probability state.

  In addition, as in the above-described example, when performing multiple forced low probability lotteries for one setting change, a flag corresponding to the number of times the forced low probability lottery is executed is stored in the memory along with the setting change, Each time the forced low probability lottery is executed, the flag is deleted one by one, and the forced low probability lottery may be executed until the flag disappears, or a value corresponding to the number of times the forced low probability lottery is executed is set in the counter. The counter value may be subtracted every time the forced low probability lottery is executed, and the forced low probability lottery may be executed until the counter value becomes zero.

  Of course, even when one forced low-probability lottery is performed for each setting change, the number corresponding to the number of games in the game section that is in the low-probability state when the forced low-probability lottery is won along with the setting change. These flags may be stored in the memory. In this case, it is only necessary to delete the flags one by one for each game and execute the forced low probability lottery only when the first flag is deleted. Similarly, in accordance with the setting change, when the forced low probability lottery is won, a value corresponding to the number of games in the game section to be in the low probability state is set in the counter, and the counter value is subtracted for each game and 1 The forced low probability lottery may be executed only at the time of the subtraction.

  Although the example in which the predetermined period is between 25 games after the setting change (end of the pseudo bonus mode) has been described, the predetermined period is not limited to this and can be freely set. In the above embodiment, an example in which the predetermined period is a period common to the first game section has been described, but the predetermined period may be an arbitrary section different from the first game section. For example, during a period of 5 games (0 to 5 game periods) after the setting change, or during a period of 30 games (0 to 30 game periods) after the setting change, the state is changed to a low probability state. May be. Thus, the period for changing to the low probability state may be at least a predetermined period (0 to X game period) after the setting is changed. Further, although the example in which the period for changing to the low probability state is only one period has been described, a plurality of periods may be changed to the low probability state. For example, the period of 0 to 5 games (part of the first game section) and the period of 60 to 70 games (part of the third game section) may be changed to a low probability state.

  In addition, although each game section has been described as being divided and set every time a game is played at a certain number of times, such as 25 times, each game section is divided every time a different number of games are played. You may do it. For example, the first game section is 25 times (0 to 25 game period), the second game section is 30 times (26 to 55 game period), the third game section is 10 times (56 to 65 game period), The fourth game section may be set such as 35 times (a period of 66 to 100 games). Moreover, although the total number of games of all the sections (the 1st game section-the 4th game section) was demonstrated in the example of 100 times, for example, this total number of games can be set freely, such as 50 times and 200 times. It's okay.

  Further, in the forced low probability lottery table 68, the probability that it is decided to change to the low probability state is set to 2/3, and the probability that it is decided not to change to the low probability state is set to 1/3. As described in the example, these probabilities may be set freely. For example, the probability of changing to the low probability state may be set to 1/3, the probability of not changing to the low probability state may be set to 2/3, You may set equally. Further, the probability of changing to the low probability state may be set to 1/1 (100%) so that the game is always started in the low probability state when the setting is changed. Of course, regardless of lottery (without providing a forced low probability lottery table or lottery means), a game may be started in a low probability state whenever a setting change is made.

  Further, the winning probability of the pseudo bonus transfer lottery in the high accuracy table is set to 70%, and the winning probability of the pseudo bonus transfer lottery in the low accuracy table is set to 30%. If the winning probability of the lottery is higher than the winning probability of the pseudo bonus transfer lottery in the low accuracy table, these winning probabilities may be set freely.

  In addition, the winning probability of the pseudo bonus transition lottery set in the high probability table and the low probability table may be different for each scenario. For example, in scenario A, the winning probability of the pseudo bonus transition lottery in the high accuracy table is set to 60%, the winning probability of the pseudo bonus transition lottery in the low accuracy table is set to 20%, and in scenario D, the winning probability in the high accuracy table is set. The winning probability of the pseudo bonus transition lottery may be set to 80%, and the winning probability of the pseudo bonus transition lottery in the low probability table may be set to 30%. In this case, for example, a high accuracy table A and a low accuracy table A used in the scenario A, a high accuracy table B and a low accuracy table B used in the scenario B, etc. are prepared. If you want to.

  Further, in the above embodiment, the example has been described in which the player can determine which state is the current state by changing the mode of production in the high probability state and the low probability state. The probability state of the winning combination (for example, a predetermined small combination) is configured to be different from the probability state, and the player checks the winning probability of the winning combination with a small combination counter or the like, so that the current state becomes a high probability state. It may be possible to determine which of the low probability states.

  In the present invention, since the scenario table used when the predetermined condition is satisfied and the scenario table used when the setting is changed are the same, the predetermined condition is simulated as in the above embodiment. The present invention is not limited to an example in which the bonus mode has ended, and the predetermined condition may be that an advantageous mode other than the pseudo bonus mode has ended. In other words, the scenario table used when the advantageous mode other than the pseudo bonus mode is ended may be the same as the scenario table used when the setting is changed. In addition, as an advantageous mode other than the pseudo bonus mode, there are a chance zone in which the probability of transition to the pseudo bonus mode is set to a high probability state, an AT mode in which the game content, production mode, and advantageous disadvantages are different from the pseudo bonus mode, Various game modes such as ART mode can be mentioned.

  Further, the predetermined condition is not limited to when the advantageous mode is ended, and the game mode other than the advantageous mode (for example, the above-described pseudo general mode, a game mode in which an increase in medals cannot be expected even if a game is performed, or a game) (Game mode in which medals decrease) may be completed.

  Moreover, since the predetermined condition is not limited to one and may be plural, for example, as the predetermined condition, two conditions of when the pseudo bonus mode ends and when the chance zone ends may be provided. Good. In this case, the same scenario table is used when the pseudo bonus mode ends, when the chance zone ends, and when the setting is changed. Of course, the predetermined condition may be three or more. That is, satisfying one or more of a plurality of preset conditions may be set as the predetermined condition.

  In the above embodiment, the example in which the probability that the player is advantageous is changed from the high probability state to the low probability state is described, but the present invention is not limited to this, and the probability that the player is advantageous is constant from the high probability state. May be reduced by a ratio (for example, 20%).
