Description

  The present invention relates to a slot machine that changes an advantageous degree on a player side by changing an internal winning probability.

  Conventionally, for example, a slot machine that generates a probability variation state in which the internal winning probability of a bonus combination is higher than a normal state is known (see, for example, Patent Document 1). In such a slot machine game, the conditions under which the probability variation state occurs or ends vary.

  In general, when a bonus game ends or when a specific small role wins, a probability fluctuation occurs, and when a predetermined number of games are consumed or a bonus is won internally, etc. The probability variation state ends at the timing. As described above, the probability variation state is generally set to end when a predetermined period elapses after the occurrence, and during that period, it can be a period in which the player has a high expectation.

  However, the conventional slot machine has the following problems. That is, the player cannot maintain a high expectation during a period in which the probability variation state has not occurred, which may cause a decrease in game motivation.

JP 2007-244559 A

  The present invention has been made in view of the above-mentioned conventional problems, and in a slot machine in which the internal winning probability varies, a slot machine having excellent characteristics that can maintain a high expectation of the player and improve the interest of the game. It is something to be offered.

The present invention includes a symbol variation display means for variably displaying a plurality of types of symbols according to a predetermined arrangement in a plurality of symbol display areas,
Game start operation means operated by the player to start the game with the game medium inserted;
An internal lottery means for executing an internal lottery for determining an internal winning combination from a plurality of types of combinations in accordance with the operation of the game start operation means;
A stop operation means operated by a player to stop the display of the variation of the symbol by the symbol variation display means;
Display control means for drawing a symbol corresponding to an internal winning combination in accordance with an operation of the stop operation means within a predetermined drawing range and stopping and displaying the symbol in the symbol display area;
Winning determination means for determining whether or not a winning has occurred based on a combination of symbols stopped and displayed in each symbol display area of the symbol variation display means;
In a slot machine comprising: a profit granting means for granting a player a profit corresponding to the winning when it is determined by the winning determining means that a winning has occurred,
The internal lottery means executes the internal lottery based on different internal winning probabilities according to the game start operation time point that is the operation time point of the game start operation means, for at least one of the plurality of types of roles. The slot machine is configured to be configured as described above (claim 1).

  The internal lottery means in the slot machine of the present invention varies the internal winning probability of any one of the combinations according to the game start operation time. In this slot machine game, the internal winning probability of any of the combinations may vary from game to game. Therefore, the player of this slot machine can maintain a high expectation for the fluctuation of the internal winning probability.

  Further, in this slot machine game, the game start operation affects not only whether the winning combination is a winning combination, but also the internal winning probability for determining whether or not it is a winning combination. Therefore, each game start operation can be a very important point in the game, and the interest is enhanced.

  As described above, the slot machine of the present invention is a slot machine that varies the internal winning probability, and is a slot machine having excellent characteristics that can maintain the player's expectation and improve the fun of the game.

The slot machine of the present invention may be a slot machine in a narrow sense using medals and coins as game media, or a parrot (R) using pachinko balls as game media.
In addition, if a role that is very advantageous to the player, such as a bonus role, is set as the target for changing the internal winning probability, the player's expectation for the fluctuation of the internal winning probability can be further increased. Further, a remarkable effect can be realized.

A first special state in which the internal winning probability of any one of the roles is set higher when the game start operation time belongs to the second period than when the game start operation time belongs to the first period;
And when the game start operation time belongs to the second period, a special state occurs that generates a second special state in which the internal winning probability of any of the roles is set higher than that of the first period. Means are preferably provided (claim 2).

  In this case, depending on whether the gaming state being generated is the first special state or the second special state, the variation tendency of the internal winning probability according to the game start operation time is completely opposite. It becomes like this. In the first special state, it is advantageous if the game start operation time belongs to the second period, but in the second special state, it is disadvantageous. In the second special state, it may be advantageous if the game start operation time point belongs to the first period. In the game of the slot machine, there is a pleasure of performing the game start operation while measuring the timing while predicting whether the game is in the first special state or the second special state.

In addition, game regulation means for regulating the start of the next game until a predetermined regulation time elapses after the game is started in response to the symbol fluctuation start by the symbol fluctuation display means,
The first period is a waiting period until the regulation time elapses after the game is finished in response to the end of the change of the symbol, and the second period is a non-waiting period after the regulation time elapses. (Claim 3).
In this case, the internal winning probability can be changed depending on whether the game start operation is performed within the standby period or the game start operation is performed within the non-standby period. By changing the internal winning probability depending on whether it is the waiting time or the non-standby time, the player can be made aware of whether or not the internal winning probability has changed at the moment the game start operation is performed.

In addition, it is preferable that operation timing notifying means for notifying the second period in the first special state and notifying the first period in the second special state is provided.
In this case, by performing the game start operation based on the notification by the operation timing notification means, it is possible to generate fluctuations in the internal winning probability that is advantageous to the player side. Here, for example, informing the second period in the first special state directly informs that the second period is in the first special state, as well as an internal winning probability that is advantageous by the game start operation. It means that the fact that it is the second period is indirectly notified by the notice that it is the period in which the fluctuation occurs.

  In addition, as the plurality of types of combinations, the first specific small combination that triggers the transition from the normal state where the internal winning probability does not change according to the game start operation time to the first special state, the normal A second specific small role that triggers a transition from a state to the second special state, a third specific small role that triggers a transition from the first special state to the normal state, and the second special state from the second special state It is preferable that a fourth specific small combination serving as a trigger for transition to the normal state is set (claim 5).

  Here, the fact that a specific small role is a trigger for the transition means that a transition can occur according to the internal winning of the specific small role, or that a shift can occur according to the winning of the specific small role. Moreover, as said 1st-4th specific small combination, all the same combination may be set, all different combinations may be set, and the same combination may be set about some specific small combinations. . When configured as described above, it is possible to increase the player's sense of expectation or give a sense of tension in accordance with the internal winning or winning of the specific small role, thereby further enhancing the interest of the game. It should be noted that it is also possible to determine whether or not to cause a state transition by lottery according to the internal winning etc. of the specific small role.

The embodiment of the present invention will be specifically described with reference to the following examples.
Example 1
This example is an example related to the slot machine 1 having a function of changing the internal winning probability. The contents will be described with reference to FIGS.

  First, the external configuration of the slot machine 1 of this example will be described with reference to FIG. In the slot machine 1, the front portion facing the player is formed by a front frame body 10 having a substantially rectangular symbol display window 11 provided substantially at the center. The front frame 10 is configured by arranging a liquid crystal display unit 53, a pair of left and right speakers 520, and a decorative lamp unit 56 on the upper side of the symbol display window 11. A base 100 that forms the base of the slot machine 1 is formed below the symbol display window 11. On the right side of the symbol display window 11, a payout number display unit 551 for displaying the number of medal payouts and a credit number display unit 552 for displaying the number of credits are arranged.

  The base portion 100 is formed so as to protrude relative to the symbol display window 11 located behind the player. The base unit 100 has a table-like operation surface 14 at the upper end adjacent to the symbol display window 11, a medal tray 15 for paying out medals (game media) at the lower end, and the operation surface 14 and the medal tray 15. And an operation panel 13.

  On the operation surface 14, a bet button 64 for inserting a medal credited (stored) by a credit function, a settlement button 65 for paying out a credited medal, and a medal insertion for directly inserting a medal A mouth 630 is arranged. The operation panel 13 is provided with a start lever 62 (game start operation means) for starting the symbol fluctuation of the reel 21 and a stop button 61 (stop operation means) for stopping the symbol fluctuation.

  The bet button 64 is a button for inserting three medals out of the credited medals. The bet button 64 generates a 3-bet signal indicating the insertion number 3. However, when the remaining credit is 2 or 1, a 2-bet signal or 1-bet signal is generated, and when the credit is zero, a bet signal is not generated.

  The start lever 62 is an operation lever that generates a game start signal that is a control signal for the reel 21 in accordance with the player's operation. In the slot machine 1, the start lever 62 is set to the valid state on the premise that a medal is inserted directly or a medal is inserted by operating the bet button 64. When a replay is won, a state where a medal is directly inserted or a medal is automatically inserted even if no betting operation is performed, that is, a state where the next game can be started can be set. Further, in the slot machine 1 of this example, the game start operation is performed within the wait period (waiting period) until the regulation time of 4.1 seconds elapses after the start of the previous game, that is, the reel 21 is started. In such a case, the reel 21 is started after the end of the wait period.

  The stop button 61 is an operation button that generates a variable stop signal that is a control signal for the reel 21 in accordance with the player's operation. The stop button 61 of this example is a combination of a left stop button 61L corresponding to the left reel 21L, a middle stop button 61C corresponding to the middle reel 21C, and a right stop button 61R corresponding to the right reel 21R.

  As shown in FIG. 1, the symbol display window 11 is a display window including symbol display areas 110L, C, and R. Each of the symbol display areas 110L, C, and R is a symbol display area for three symbols. In the entire symbol display window 11, symbol display regions for nine symbols arranged in a two-dimensional matrix composed of three rows and three columns are formed. The symbol display window 11 is formed of a transparent resin plate so that the symbol 20 can be seen from the player side.

  In the symbol display area in which nine symbols 20 are arranged in a two-dimensional matrix, winning lines 211 to 215 that are the arrangement direction of winning symbols to be awarded are set. The winning line of this example is composed of horizontal winning lines 211 to 213 and diagonal winning lines 214 and 215.

  Reels 21L, C, and R constituting the symbol variation display means 2 are arranged on the back side of the symbol display areas 110L, C, and R, respectively. As shown in FIG. 2, the reels 21 </ b> L, C, and R are rotary reels having a cylindrical shape and 21 symbols 20 arranged on the outer peripheral surface thereof at substantially constant intervals. The reel 21 may be an image-type reel that displays the symbols on the liquid crystal display in place of the rotary reel of this example.

As shown in FIG. 1, the speaker 520 and the decorative lamp unit 56 are rendering means for rendering a game with sound or light.
The payout number display unit 551 is a display unit that displays the number of medals paid out at the time of winning a prize.
The credit number display unit 552 is a display unit that displays the number of medals credited (stored) by the credit function.

  The liquid crystal display unit 53 includes a liquid crystal display. The liquid crystal display unit 53 can display various effect screens for directing the game, such as an operation timing notification screen 490 (FIG. 9) for notifying the operation timing of the start lever 62 which is advantageous to the player side. The contents of the operation timing notification screen 490 will be described later.

Next, the role, game play, and symbol arrangement of the slot machine 1 of this example will be described.
In the slot machine 1, as shown in FIG. 3, a combination, an internal winning combination, and a winning combination are set. In addition to three types of bonus combinations (BIG1, BIG2, REG), small combinations such as a 10-sheet combination and a 2-sheet combination, and replay are set as combinations. In the figure, the name of each combination is shown in the left column, a winning symbol that is a combination of symbols 20 corresponding to each symbol is shown in the middle column, and profits given to the player in accordance with winning are shown in the right column.

  In the slot machine 1, the winning combination internally by the internal lottery means 41 becomes the internal winning combination. When the winning symbol corresponding to the internal winning combination is established along the winning line, the winning combination becomes the winning combination. In the game of the slot machine 1, a bonus state can occur in accordance with the winning of the bonus combination. The BIG bonus state triggered by BIG1 and BIG2 is the most advantageous bonus state that ends when the number of medals paid out exceeds 365. The REG bonus state triggered by REG is a bonus state that ends when the number of medals paid out exceeds 120.

  In the game of the slot machine 1, a normal state, a first special state, and a second special state can occur as non-bonus states. The first special state and the second special state are states in which a probability variation game in which the internal winning probability increases according to the game start operation time point that is the operation time point of the start lever 62 can occur. Furthermore, as the first special state and the second special state, there are a state where a game start operation timing capable of generating a probability variation game is notified and a state where the game start operation timing is not notified. The state transition from the normal state to the first special state and the second special state may occur according to the internal winning of the two-piece combination (first and second specific small combinations) in the normal state. The transition from the first special state and the second special state to the normal state occurs in response to the internal winning of the 10-sheet combination (the third and fourth specific small combinations) in the first special state and the second special state. there is a possibility.

  In the slot machine 1 of this example, the special 1 flag corresponding to the first special state and the special 2 flag corresponding to the second special state are set as the gaming state flag, and the bonus state flag corresponding to the bonus state is the gaming state. It is set as a flag. Furthermore, a state notification flag corresponding to the presence of notification of the game start operation timing is set.

  Next, the electrical configuration of the slot machine 1 of this example will be described with reference to FIG. For the control unit 3 that controls the overall operation of the slot machine 1, in addition to the above-described configuration, the inserted medal detection unit 63 that detects medals inserted directly through the medal insertion slot 630 and the reel 21 together with the symbol variation display Various display units including a reel driving unit 22 constituting the means 2, a reference position detecting unit 66 for detecting the rotational position of the reel 21, a medal paying unit 54 for paying out medals, the payout number display unit 551 and the credit number display unit 552. 55, a set value operation unit 68 for setting a set value representing the player's degree of advantage, an audio output unit 52 for controlling the speaker 520, and the like are electrically connected.

  The inserted medal detection unit 63 is a detection unit for a medal inserted directly from the medal insertion port 630. The inserted medal detection unit 63 outputs an insert signal every time a medal is inserted from the medal insertion slot 630. In the slot machine 1 of this example, when three medals are inserted in response to direct insertion of medals, operation of the bet button 64, or replay winning, the start lever 62 is set to an effective state, and a new one is set. It becomes a state that can start a simple game.

The reel driving unit 22 includes a stepping motor (not shown) that can be controlled in units of steps, and is means for rotating the reel 21 by the rotational driving force of the stepping motor.
The reference position detection unit 66 is a detection unit that detects the passage of the reference position piece for each of the reels 21L, 21C, and R and outputs a detection signal.

The medal payout unit 54 is a payout unit that pays out a predetermined number (see FIG. 3) of medals to the medal tray 15 in accordance with winning.
The set value operation unit 68 is an operation unit for changing set values of 6 stages having different winning probabilities such as bonus combinations using the setting key 680.

  As shown in FIG. 4, the control unit 3 includes a CPU 31, a ROM 33 and a RAM 34 as memory means, an I / O unit 32 as an input / output interface, a random number generator 350 for generating random numbers, and a random number for internal lottery. And a random number extraction unit 35 for extracting. The CPU 31 executes a software program read from the ROM 33 to thereby determine a winning determination unit 44 for determining a winning symbol, a display control unit 43 for controlling the reel 21, an internal lottery unit 41 for lottering an internal winning combination, and an internal winning combination. Flag control means 42 for controlling the corresponding internal winning flag, profit granting means 45 for giving a profit according to winning, special state generating means 46 for generating the first special state and the second special state, and game start within a predetermined period Each function is realized as a game restricting means 47 for restricting the state and a state transition lottery means 48 for executing a state transition lottery from the normal state to the special state.

  The ROM 33 which is a memory means includes an internal lottery table used for lottery of an internal winning combination, a state transition lottery table used for state transition lottery, and a reel control table (not shown) used by the display control means 43 for stop control of the reel 21. Is remembered.

  As shown in FIG. 5, the internal lottery table includes two types of tables that are applied to a game in a non-bonus state and one type of table that is applied to a bonus state. The internal lottery table for the non-bonus state is applied to the low probability table applied to the low probability game with the normal internal winning probability including the normal state and the high probability game which is a probability variation game in which the internal winning probability is increased. And a high probability table. As an internal lottery table for the bonus state, there is a bonus table. The internal lottery table is set for each set value of 1 to 6.

  Each internal lottery table is a data table in which a range of winning random numbers for each combination is defined from 0 to 65535 lottery random numbers. The number of winning random numbers and the internal winning probability of each combination in each internal lottery table are as shown in FIG. In the probability column in the figure, the denominator (for example, x in 1 / x) of each internal winning probability is shown. As can be seen from the figure, the internal winning probability of bonus combination by the high probability table is 5 times that of the low probability game, and the internal winning probability of replay by the high probability table is 1.5 times that of the low probability game. . In addition, regarding the two-piece combination and the ten-piece combination, which are specific small combinations that trigger the state transition between the normal state and the special state, there is no difference between the high probability table and the low probability table.

  The state transition lottery table includes a first state transition lottery table (FIG. 6) from the normal state to the special state and a second state transition lottery table (FIG. 7) from the special state to the normal state. The first state transition lottery table is a lottery table for further collation with the random numbers for lottery that can be collated with the winning random numbers of the double winning combination in the internal lottery table and have generated the internal winning of the double winning combination. The second state transition lottery table is a lottery table for further collation with the random numbers for lottery that can be collated with the winning random numbers of the 10-piece combination in the internal lottery table.

  In the first state transition lottery table, as shown in FIG. 6, a special random number that causes a state transition from the normal state (“communication” in the figure) to the first special state (“special 1” in the figure). , A range of special 2 random numbers that cause state transition to the second special state (“special 2” in the figure) and other random numbers that do not cause state transition are defined. As the special 1 random number and the special 2 random number, there are a random number corresponding to the state with the notification of the game start operation timing (subscript “A” in the figure) and the state without the notification (subscript “B” in the figure). Corresponding random numbers are set. In the slot machine 1 of this example, the 1000 winning random numbers of two special roles, which are specific small roles, are classified into the following five types of random numbers.

The type of random number defined in the first state transition lottery table (1) The winning random number for transition from the normal state to the first special state (with notification of the game start operation timing). The number of special 1 random numbers with notification is 125.
(2) Winning random number for transition from the normal state to the first special state (no notification of the game start operation timing). The number of special 1 random numbers without notification is 125.
(3) Winning random number for transition from the normal state to the second special state (with notification of the game start operation timing). The number of special 2 random numbers with notification is 125.
(4) Winning random number for transition from the normal state to the second special state (no notification of the game start operation timing). The number of special 2 random numbers without notification is 125.
(5) Loss random numbers without a transition from the normal state to the special state. The number of lost random numbers is 500.

  As shown in FIG. 7, the second state transition lottery table defines a range of normal random numbers that cause a state transition from a special state to a normal state and other random numbers that do not cause a state transition. In the slot machine 1 of the present example, the 8500 winning random numbers for the 10 small roles that are specific small roles are classified into the following two types of random numbers. In the figure, the normal state is represented by “communication”, the first special state is represented by “special 1”, and the second special state is represented by “special 2”.

-Types of random numbers defined in the second state transition lottery table (1) Winning random numbers for transition from the first special state and the second special state to the normal state. The number of normal random numbers is 1500.
(2) Loss random numbers without a transition from the special state to the normal state. The number of lost random numbers is 7000.

As shown in FIG. 4, the random number generator 350 is a part that generates random numbers belonging to a predetermined integer range. The random number generated by the random number generator 350 includes a random number in the integer range of 0 to 65535 for drawing the internal winning combination.
The random number extraction unit 35 is a part for extracting lottery random numbers. The random number extraction unit 35 extracts lottery random numbers from the random numbers generated by the random number generation unit 350. The random numbers for lottery extracted by the random number extraction unit 35 include random numbers ranging from 0 to 65535 for the internal winning combination lottery or the state transition lottery. The random number extraction unit 35 extracts a random number for lottery used for lottery or the like of an internal winning combination triggered by a game start signal corresponding to the operation of the start lever 62.

  The internal lottery means 41 is a means for determining an internal winning combination by internal lottery. The internal lottery means 41 collates the lottery random numbers with respect to the winning random numbers of each combination specified in the internal lottery table (FIG. 5) to determine the internal winning combination. The internal lottery means 41 uses a bonus table in the bonus state, and uses a high probability table (probability game) or a low probability table in the non-bonus state.

  The flag control means 42 is a means for controlling an internal winning flag corresponding to the internal winning combination. The flag control means 42 sets the internal winning flag corresponding to the internal winning combination determined by the internal lottery means 41 to the ON state. The internal winning flags of other combinations other than the bonus winning combination are reset to the off state (zero) before starting the next game, regardless of whether or not the game in which the internal winning flag is established is won for the first time. Therefore, if each combination other than the bonus combination is not won in the internal winning game, all will be missed. On the other hand, regarding the bonus flag which is the internal winning flag of the bonus combination, the established state of the internal winning flag is sequentially carried over to the next game until winning, and is reset to the off state according to winning.

  The state transition lottery means 48 is a means for executing a lottery to determine whether or not to cause a state transition between a normal state and a special state when a two-piece combination or a ten-piece combination which is a specific small combination is won internally. . When the lottery random number extracted in the normal state can be compared with the winning random number of the double winning combination (that is, when the double winning combination is won internally), the state transition lottery means 48 uses the lottery random number for the first lottery. The lottery table for transition to the special state is executed in comparison with the state transition lottery table (see FIG. 6). Further, the state transition lottery means 48, when the random number for lottery extracted under the special state can be compared with the winning random number for 10 winning combinations (that is, when the 10 winning combination is won internally) The lottery to shift to the normal state is executed in comparison with the second state shift lottery table (see FIG. 7).

  The state transition lottery means 48 sets the special 1 flag (special 2 flag) to the ON state when the random number for lottery can be compared with the special 1 random number (special 2 random number) in the first state transition lottery table. Further, when the lottery random number can be compared with the special 1 random number (special 2 random number) with notification, the state notification flag is set to the on state. When the random number for lottery can be compared with the normal random number in the second state transition lottery table, all the special 1 flag, special 2 flag and state notification flag are reset.

  The display control means 43 is means for starting the symbol variation of the reel 21 in response to the game start signal and stopping the symbol variation of the reel 21 in response to the variation stop signal. The display control means 43 inputs a control pulse to the stepping motor constituting the reel driving unit 22 and rotates the stepping motor by one step for each pulse. The display control means 43 counts the number of control pulses input to the reel drive unit 22, that is, the number of steps rotated by the stepping motor. In particular, the display control means 43 of this example counts the number of steps generated after the most recent detection signal by resetting the number of steps to zero each time the detection signal of the reference position piece of each reel 21 is fetched.

  The display control means 43 is a means for executing so-called pull-in control in which symbols within a predetermined pull-in range determined by rules (rules for game machine authorization and type verification, etc.) are stopped on the winning line. In this example, as described above, a range corresponding to four symbols is set as the pull-in range. The display control means 43 determines the stop position by comparing the number of steps when the change stop signal is taken in with the reel control table. The display control means 43 pulls the symbol corresponding to the determined stop position and stops the reel 21.

  The winning determination unit 44 is a unit that determines whether or not a winning has occurred based on a combination of symbols that the three reels 21L, 21C, 21R stop display. Specifically, the winning determination means 44 determines the winning combination according to the combination of symbols stopped on the winning lines 211 to 215 set so as to cross the three reels 21L, 21C, 21R. The winning determination means 44 takes in the number of steps of each stepping motor (reel driving unit 22) corresponding to each reel 21L, C, R after each reel 21L, C, R stops. The winning determination means 44 obtains the type of the symbol 20 stopped on the winning lines 211 to 215 based on the number of steps, and determines whether or not a winning combination is established for the combination of the symbols 20.

  The profit giving means 45 is a means for giving a profit corresponding to the winning combination determined by the winning determination means 44. For example, when BIG1 and BIG2 which are bonus combinations are winning combinations, the profit granting means 45 gives a profit that the BIG bonus state occurs. When the 10 winning combination is a winning combination, a benefit of paying out 10 medals is given. When the replay is a winning combination, a benefit of generating a replay game is given.

  The game restricting means 47 is means for restricting the start of the game within a predetermined period. In the slot machine 1 of this example, as shown in FIG. 8, after the game is started by the start of symbol change in response to the start of the reel 21, a regulation time of 4.1 seconds is set. The game regulation means 47 does not start the reel 21 immediately even if the start lever 62 is operated within the wait period (first period, standby period) until the regulation time elapses, and waits for the expiration of the wait period. 21 start is permitted. For example, when the start lever 62 is operated at the game start operation time point A within the wait period, the reel 21 is started and the game is started when the wait period expires.

  On the other hand, when the start lever 62 is operated at the game start operation time point B within the non-wait period (second period, non-standby period), the reel 21 is immediately started and the game is started. The wait period is a period that can occur when all the reels 21 are stopped and the game is finished before the regulation time has elapsed after the game is started. In the slot machine 1 of this example, a wait flag corresponding to the wait period is set.

  The special state generating means 46 is a means for generating a first special state and a second special state. The special state generating means 46, for example, generates a first special state with notification of the game start operation timing when two winning combinations are won internally by the special one random number with notification in the normal state. Further, for example, when the 10 winning combination is won internally by the normal random number in the first special state and the second special state, the special state is ended and the normal state is restored.

  In the first special state, the low probability table is applied to the game when the game start operation time point belongs to the wait period, and the high probability table is applied to the game when the game start operation time belongs to the non-wait period, and a probability variation game is generated. . On the other hand, in the second special state, when the game start operation time belongs to the wait period, the high probability table is applied to the game, and the probability variation game is generated, and when the game start operation time belongs to the non-wait period, the low probability table is the game. Applies to That is, in the first special state, the operation of the start lever 62 within the non-wait period is advantageous, while in the second special state, the operation of the start lever 62 within the wait period is advantageous. If the start lever 62 is operated during the wait period, the reel 21 is started after the end of the wait period and the game is started.

  Next, the operation timing notification screen 490 displayed by the liquid crystal display unit 53 will be described with reference to FIG. The operation timing notification screen 490 is a screen displayed by the operation timing notification means 49 when the special 1 flag or the special 2 flag is on and the state notification flag is on.

  The operation timing notification screen 490 includes a state display column 490A indicating that it is a special state and a chance that a probability variation game (high probability game with a high internal winning probability) will occur, and a game start operation timing for generating the probability variation game. It is the screen which has arrange | positioned the timing alerting | reporting column 490B which alert | reports. The timing notification column 490B of the operation timing notification screen 490 illustrated in FIG. 9A notifies the fact that there is no probability change even if the start lever 62 is operated by a character string “STOP!”. The timing notification column 490B of the operation timing notification screen 490 illustrated in FIG. 5B notifies that a change in probability can occur if the start lever 62 is operated by a character string “START!”.

  The operation timing notification screen 490 of FIG. 9A is a screen displayed during the wait period in the first special state. The operation timing notification screen 490 in FIG. 5B is a screen displayed in the non-wait period in the first special state and the wait period in the second special state.

  Next, the operation of the slot machine 1 of this example configured as described above will be described with reference to the flowcharts of FIGS. FIG. 10 is a flowchart showing the flow of the internal lottery process. FIG. 11 is a flowchart showing the flow of the state transition lottery process.

  In the internal lottery process shown in FIG. 10, first, the start of the game is determined (S101). When the game is started (S101: YES), lottery random numbers are extracted (S102). Then, an internal lottery table to be applied is selected according to the flag state of the game state flag and the wait flag (S103), and the extracted lottery random numbers are collated (S104).

  For example, if the special 1 flag is on and the wait flag is on, that is, if the game start operation is within the wait period under the first special state, the low probability table is selected. The When the special 2 flag is in the on state and the wait flag is in the on state, that is, when the game start operation is in the wait period under the second special state, the high probability table is selected and the probability variation game is selected. Will occur. When the bonus state flag is on, the bonus table is selected regardless of the flag state of the wait flag. Thereafter, after the internal winning flag corresponding to the internal winning combination is set to the on state (S105), the state transition lottery P1 is executed.

  In the state transition lottery process P1 shown in FIG. 11, it is first determined whether or not the normal state is set (S201). If it is the normal state (S201: YES), the flag state of the double winning flag, which is the internal winning flag of double winning, is determined (S202). If the double winning flag is on (S202: YES), the random number for lottery extracted in step S102 is collated with the twelfth state transition lottery table (FIG. 6) (S203). If the special 1 random number can be verified (S204: YES), the special 1 flag corresponding to the first special state is set to the on state (S205). On the other hand, when the special 2 random number can be collated (S211: YES), the special 2 flag corresponding to the second special state is set to the on state (S212). Further, when the lottery random number is collated with the special 1 random number or special 2 random number with notification (S206), the state notification flag is set to the on state (S207).

  On the other hand, when it is not the normal state (S201: NO) and is in the first special state or the second special state (S221: YES), the flag state of the 10-sheet combination flag which is the internal winning flag of 10-sheet combination is determined. (S222). When the 10-piece winning flag is on (S222: YES), the random number for lottery extracted in step S102 is collated with the second state transition lottery table (FIG. 7) (S223). When the lottery random number can be compared with the normal random number (S224: YES), the special 1 flag and the special 2 flag are reset (S225). Further, when the state notification flag is in the on state (S226: YES), it is reset to the off state (S227).

  As described above, in the special state in which the slot machine 1 of the present example is generated, there is a chance that the probability variation game in which the internal winning probability is increased is generated each time. In the first special state, a probability variation game can occur in response to a game start operation within a non-wait period, so that the player's advantage can be improved by repeating the game at a relatively slow pace. On the other hand, in the second special state, a probability variation game may occur in response to a game start operation within the wait period, so that the player's advantage can be improved by digesting the game at a fast pace.

  As described above, in the slot machine 1 of this example, the probability variation game can be generated according to the operation timing of the start lever 62. Therefore, the player can be actively involved in the occurrence of the probability variation game and can play a game strategically. Furthermore, there are cases where the game start operation timing at which a probability variation game may occur is notified or not notified, and there is a pleasure of predicting the type of special state when not notified.

In general slot machine games, the game progress pace tends to be constant, while in the slot machine 1 game of this example, the motivation to intentionally increase or decrease the progress pace is made. The monotony of the game is suppressed.
In the slot machine 1, since the internal winning probability of replay is set to be different between the low probability table and the high probability table, when the game start operation timing is not notified, the high probability table is referred according to the winning situation of the replay. It is possible to guess the game start operation timing to be played. The combination that is set so that the internal winning probability is different between the low probability table and the high probability table is not limited to replay, and any small combination may be used.
If the game start operation timing is not notified in the first special state and the second special state, only the fact that any special state has occurred is notified, and the player himself determines which special state is in effect. It is desirable to direct as you guess.

  As described above, the slot machine 1 of the present example is a slot machine that varies the internal winning probability, and can maintain a high level of player's expectation of the probability change over the entire period of occurrence of the special state. It is a slot machine with excellent characteristics that can improve.

  In this example, the non-wait period is set as a second period that is an advantageous game start operation period in the first special state, and the wait is set as the first period that is an advantageous game start operation period in the second special state. It is an example in which a period is set. Alternatively, the first period and the second period may be alternately generated according to the elapsed time after the start of the previous game. For example, the elapsed time from the start of the previous game is 3 to 4 seconds, 5 to 6 seconds, and 7 to 8 seconds are set as the first period, and the remaining period is set as the second period. Can do.

In this example, the state transition lottery was performed using a random number for lottery in which the two-piece combination and the ten-piece combination, which are specific small roles, were won internally. Accordingly, a random number for state transition lottery may be separately extracted.
Further, in this example, the state transition lottery is performed according to the internal winning of the specific small role, but it is also possible to execute the state transition lottery according to the winning of the specific small role. Furthermore, it is also possible to execute the state transition lottery regardless of the internal winning of the specific small combination.

  In this example, two types of low probability table and high probability table are set as the internal lottery table to be applied to the special state. Instead, three or more types of internal lottery tables are set. Also good.
