Description

  The present invention includes a variable display unit capable of variably displaying a plurality of types of identification information each identifiable. After the variable display unit is variably displayed, the display result is obtained by stopping the variable display of the variable display unit. The present invention relates to a slot machine that can derive and win according to the display result.

  A slot machine generally includes a variable display device having a plurality of (usually three) reels having a plurality of types of symbols as identification information drawn on the outer periphery, and each reel has a start lever by a player. Rotation is started by operating, and when the player operates a stop button provided corresponding to each reel, the rotation is stopped within a range of a predetermined maximum delay time from the operation timing. . A winning is generated according to the display result derived when the rotation of all reels is stopped.

  The types of winning combinations include small roles, special roles, and re-playing roles. Here, in the winning of a small role, the player can obtain a profit that a predetermined number of medals are paid out for each type of small role. In the special role winning, the player can obtain a profit that the next game is shifted to a gaming state advantageous to the player, such as a regular bonus or a big bonus. In the winning of the re-gamer, it is possible to obtain a profit that the next game can be performed without consuming new medals for setting the number of bets.

  In order for winning of each combination to occur, generally, it is a condition that a winning is made by an internal lottery performed in advance (usually when the start lever is operated). In addition, the combination of symbols constituting the winning combination in the internal lottery is aligned with the effective line, and the combination of symbols configuring the winning combination not selected in the internal lottery is not aligned with the effective line. Reel control is performed.

  In such a slot machine, when a specific winning combination is won in the internal lottery, the operation procedure for winning the specific winning combination is controlled to an advantageous state of so-called AT so as to notify information that can be specified. In some cases, a lottery to determine whether or not to control by the AT is performed based on the total points acquired by the player during a predetermined period (for example, Patent Document 1).

JP 2010-238881 A

  However, in the slot machine of Patent Document 1, the period during which the right relating to the transition of the advantageous state such as points is fixed, and by changing the length of the period during which the right is granted, the advantage for the player It was not considered to change.

  The present invention has been conceived in view of such circumstances, and its purpose is to provide a slot machine that can change the advantage for a player by changing the length of a period during which a right related to a transfer lottery is granted. Is an offer.

(1) Provided with a variable display unit capable of variably displaying a plurality of types of identification information each capable of being identified,
In the slot machine (for example, slot machine 1) in which a winning result can be generated according to the display result after the variable display portion is variably displayed, the display result is derived by stopping the variable display of the variable display portion.
Lottery means (for example, main control unit 41) for performing lottery regarding the transition to an advantageous state (for example, AT) advantageous to the player;
Granting means (for example, the main control unit 41) for granting the right relating to the lottery (for example, the CZ game of the first embodiment, the point of the third embodiment) during the accumulation period (for example, the stock period);
Storage means for storing and storing the rights granted during the accumulation period (for example, the main control unit 41);
A first state (for example, the first state having a low replay probability in the first embodiment) and a second state in which the right is more easily given during the accumulation period than the first state (for example, the replay in the first embodiment) State control means (for example, main control unit 41) for controlling to any one of a plurality of types of states including a second state in which the number of CZ games is likely to be given because the probability is higher than in the first state. ,
The lottery means performs the lottery according to the right stored in the storage means when the accumulation period ends (for example, when the stock period ends, the lottery means shifts to the CZ state where the AT lottery probability is high and grants According to the number of CZ games played)
The second state has a higher probability of the accumulation period being longer than the first state (for example, the stock period is longer in the second state than in the first state as shown in FIG. 17B). To be set).

  According to such a configuration, when being controlled to the second state, it is easier to grant the right for lottery than when being controlled to the first state, and the accumulation period during which the right is granted is the first. It tends to be longer than when it is controlled to one state. Therefore, the player is more advantageous when controlled to the second state than when controlled to the first state.

(2) In the slot machine according to (1) above,
It further includes a pre-determining means (for example, an internal lottery process) for determining whether or not to allow the winning
The granting means grants an advantageous game (for example, a CZ game) to win the lottery with a higher probability than usual as a right related to the lottery,
The accumulation period is continued until the game in which the lottery unit executes the lottery (for example, the stock period is until the transition to the CZ state)
The lottery means performs the lottery according to the number of advantageous games stored in the storage means (controls to the CZ state according to the CZ game given during the stock period, and performs AT lottery),
The pre-determining means includes
During the first state (for example, RT1), a re-game winning that allows the variable display unit to be variably displayed without using a gaming value with a first probability (for example, a probability of 1/7) is allowed. ,
During the second state (for example, RT0, 2), the replay winning is allowed with a second probability (for example, a probability of 1/3) higher than the first probability.

  According to such a configuration, when being controlled to the second state, it is easier to grant the right for lottery than when being controlled to the first state, and the accumulation period during which the right is granted is the first. It tends to be longer than when it is controlled to one state. Therefore, the player is more advantageous when controlled to the second state than when controlled to the first state.

(3) In the slot machine according to (2) above,
The state control means includes
Control to a third state (eg, RT2),
Performing control to shift from the first state (for example, RT1) to the second state (for example, RT0),
Performing control to shift from the second state to the third state;
In the case of controlling to the second state, based on the fact that the pre-determining means has allowed the generation of the transition re-game prize among the re-game prizes (for example, when winning the fall replay) Control to shift to 1 state,
Control that shifts to the first state based on the fact that the pre-determining means allows the generation of the transition replay winning when the third state is controlled (for example, when winning the fall replay) And
In the third state, the pre-determining means allows the replay prize to be generated with the second probability that the second game is allowed to occur during the second state, and the second state The transition re-game winning is allowed with a probability lower than the probability that the transition re-game winning is permitted (for example, as shown in FIG. 21, the probability of winning the Lip GR 11-13 is set to RT0). Set to be higher when controlled than when controlled by RT2),
The period controlled to the second state and the period controlled to the third state are both the accumulation period (for example, while being controlled to RT0 or RT2 as in the second embodiment). Is always controlled as a stock period)
The advantageous game is awarded when the first state is shifted to the second state or when the second state is shifted to the third state (for example, from RT1, as in the second embodiment). A privilege granting means (for example, the main control unit 41) is further provided when a transition is made to RT0 and when a transition is made from RT0 to RT2.

  According to such a configuration, since the occurrence of the transition replay winning, which is an opportunity to shift from the second state or the third state to the first state, is less likely to be permitted during the third state, the control is switched to the second state. The period controlled to the third state is likely to be longer than the period to be performed. The period controlled to the second state and the period controlled to the third state are both accumulation periods. Therefore, when controlled to the third state, the accumulation period during which the right related to the lottery is granted tends to be longer than when the storage period is controlled to the first state or the second state. Therefore, when being controlled to the third state, it becomes more advantageous for the player than when being controlled to the first state or the second state.

(4) In the slot machine according to (1) above,
It further comprises a pre-determining means for determining whether or not to allow a prize to be generated,
The state control means includes
Compared to the first state and the second state, it is controllable to a special state (for example, BB1, BB2) that has a higher probability of allowing a prize to be awarded (for example, a small role) accompanied by a game value. And
Perform control to shift from the special state to the first state or the second state (for example, shift to RT3 after BB1 ends, shift to RT4 after BB2 ends),
Based on the fact that the transition re-game prize is allowed to be generated out of the re-game prizes that the variable display unit can variably display without using the game value when controlling to the first state ( (For example, when you win a fall replay)
In the case of controlling to the second state, transition to another gaming state is made based on the fact that the advance determination means allows the occurrence of the transition re-game winning (for example, when winning the fall replay). Control
The pre-determining means allows the occurrence of the replay prize with the same probability (for example, 1/7 probability) in the first state and the second state,
In the second state, the probability that the transition re-game winning is permitted is lower than in the first state (for example, as shown in FIG. 23 (A), the probability of winning the lip GR11-13). Is set to be higher when RT3 is controlled by RT3 than when RT4 is controlled)
The granting means grants points (points are awarded as shown in FIG. 23 (B)) as the right based on the fact that the predetermining means allows the occurrence of the winning prize,
The lottery means executes the lottery so that the larger the total number of points stored and stored by the storage means, the higher the probability of winning the lottery (for example, as shown in FIG. The higher the chance of winning the AT lottery)
In the second state, the expected value of the point given during the accumulation period is higher than the expected value of the point given during the first state (for example, as shown in FIG. 23B). In addition, points are more easily awarded when controlled by RT4 than when controlled by RT3).

  According to such a configuration, the right relating to the lottery regarding the transition to the advantageous state can be granted in the first state and the second state after the control of the special state having a high probability that the generation of the winning prize is permitted is completed. Therefore, since the game after the special state is finished can be expected, the interest of the game after being controlled to the special state is improved.

(5) In the slot machine according to (1) above,
It further comprises a pre-determining means for determining whether or not to allow a prize to be generated,
The granting means is based on the fact that the pre-decision means allows the occurrence of a special prize (for example, the middle cherries in the fourth embodiment, the normal replay in the [Modified example of the fourth embodiment] column of the modified example). Granting the right,
The accumulation period is a period controlled in the first state (for example, BB1, a precursor period in RT1 in the column of [Modification of Fourth Embodiment] of the modification), or the second state (for example, BB2, a precursor period during RT2 or RT3 in the column of [Modification of Fourth Embodiment] of the modification,
The pre-determining means includes
During the first state, the special prize is allowed to occur with a first probability (for example, a probability of 1/3),
During the second state, the special prize is allowed to occur with a second probability (for example, a probability of 1/2) higher than the first probability,
The period controlled to the first state is a first game number (for example, 3 games),
The period controlled to the first state is a second game number (for example, five games) larger than the first game number.

  According to such a configuration, since the accumulation period is a fixed game number such as the first game number or the second game number, the accumulation period is shorter than that in the first state although the accumulation period is in the second state. There is no. Therefore, the dissatisfaction of the player who feels when the accumulation period becomes shorter than in the first state in spite of being in the second state does not occur.

(6) In the slot machine according to (1) above,
It further comprises a pre-determining means for determining whether or not to allow a prize to be generated,
The accumulation period is a period controlled in the first state (stock period set in RT1, 3-5) or a period controlled in the second state (stock set in RT0, 2). Period)
The granting means grants points as the right based on the fact that the predetermining means has allowed the generation of a prize-winning with the provision of game value,
The lottery means executes the lottery so that the greater the total amount of points accumulated and stored by the storage means, the higher the probability of winning the lottery,
The pre-determining means allows the occurrence of the prize winning with the same probability in the first state and the second state (for example, in RT0 to RT4, the probability of winning a bell, cherry, or watermelon is The same),
During the second state, compared to the first state, the number of points awarded when the generation of the prize is permitted is larger (as shown in FIG. 30B, control is made to RT0 or RT2. Points are more easily awarded when compared to when RT1 or 3-5 is controlled)
The state control means includes
During the first state, it is determined whether to continue the control of the first state with a first probability (for example, 70% or 50% as shown in FIG. 30C) for each game.
Whether the control of the second state is continued with a second probability higher than the first probability for each game (for example, 90% or 80% as shown in FIG. 30C) during the second state. Decide whether or not.

  According to such a configuration, since the period controlled to the first state or the second state, which is the accumulation period, is determined by continuous lottery for each game, the accumulation period may be longer than expected. is there. Therefore, the interest of the game during the accumulation period is improved.

(7) In the slot machine according to any one of (1) to (6) above,
A period suggesting effect (for example, the numeral 5 shown in FIG. 18B, a character image “sound chance” in the column of “period suggesting effect” in the modification example, voice) indicating that the accumulation period is in progress. It further includes a period suggesting effect executing means (for example, sub-control unit 91) to be executed,
The period suggesting effect executing means is:
When it is controlled to the first state and suggests that it is during the accumulation period, the period suggesting effect is the first effect (for example, the number 5 in the first state column of FIG. 18B). Is displayed in a black square frame)
When suggesting that it is during the accumulation period when controlled to the second state, the period suggesting effect is an effect that emphasizes that the accumulation period is in effect rather than the first effect. Two effects (for example, a display in which the number 5 in the second state column in FIG. 18B is surrounded by a red square frame) are executed.

  According to such a structure, since the period suggestion effect differs between the first state and the second state, the interest of the game is improved. Further, in the second state that is more advantageous than the first state with respect to the accumulation period, the player performs the second effect because the second effect that emphasizes the accumulation period is performed rather than the first effect. Can be expected, and the interest of the game is improved.

(8) In the slot machine according to any one of (1) to (7),
Rights suggestion effect execution means (for example, a star displayed under the characters “Stock” shown in FIG. 18A) indicating the number of rights stored and stored in the storage means (for example, a star displayed under the characters “Stock” shown in FIG. 18A) And a sub-control unit 91),
The right suggestion effect execution means changes the effect mode of the right suggestion effect so that the more the number of rights is, the more the effect mode is emphasized (the number of CZ games accumulated during the stock period is changed to a star). Display in number).

  According to such a configuration, the player can check the number of rights accumulated by the storage unit based on the effect mode of the right suggestion effect.

(9) In the slot machine according to (7) or (8) above,
The period suggesting effect executing means executes the period suggesting effect by a specific operation by the player (for example, an operation to the effect switch 56),
The right suggestion effect executing means executes the right suggestion effect by the specific operation.

  According to such a configuration, the period suggestion effect and the right suggestion effect are executed when the player performs the specific operation, so that the interest of the game for performing the specific operation is improved.

  An embodiment for implementing a slot machine according to the present invention will be described below. In the following embodiments, an example in which the present invention is applied to a slot machine will be described.

[First Embodiment]
[Configuration of slot machine]
FIG. 1 is a front view showing the overall structure of the slot machine 1 according to the present embodiment. The slot machine 1 includes a housing 1a having an open front surface and a front door 1b pivotally supported on a side end of the housing 1a. A liquid crystal display 51 is provided at the upper center of the front door 1b. The liquid crystal display 51 has a display area 51a, and the transmission area 51b corresponding to the see-through window 3 can be transmitted. Accordingly, a predetermined effect can be executed in the display area 51a, and the reels 2L and 2C arranged in parallel inside the housing 1a through the transparent window 3 through the transmission area 51b of the display area 51a. 2R (hereinafter also referred to as a left reel, a middle reel, and a right reel) becomes visible. FIG. 2 is a diagram showing a symbol arrangement of each reel. On the reels 2L to 2R, a plurality of types of symbols that can be identified are arranged in a predetermined order. The number of reels is not limited to three, and may be one or two or more. Moreover, although the variable display part has shown the example comprised by the physical reel, you may be comprised by image display apparatuses, such as a liquid crystal display.

  At the lower right of the liquid crystal display 51, a medal insertion portion 4 into which medals can be inserted is provided, and at the lower part of the front door 1b, a medal payout opening 9 through which medals are paid out and speakers 53, 54 are provided.

  Further, as an example of the operation means, the front door 1b is set with a specified number of bets determined according to the gaming state within the credit range stored as the gaming value (the number of medals) owned by the player. The MAXBET switch 6 that is operated when the game is performed, the settlement switch 10 that is operated when the credit and the set bet number are settled and returned, the start switch 7 that is operated when the game is started, and the reels 2L to 2R Stop switches 8L, 8C, and 8R that are operated when the rotations are stopped are provided, an effect switch 56 for use in effects, and the like.

  The front door 1b is provided with a game display unit 13 for notifying information related to a game as an example of a notification unit. The game display unit 13 includes a credit display 11 that displays the number of medals stored as credits, a game auxiliary display 12 that displays a medal payout number and an error code when an error occurs, and a set bet. 1BETLED14 for informing the number, 2BETLED15, 3BETLED16, insertion request LED17 for informing that the medal can be inserted, start valid LED18 for informing that the game can be started by operating the start switch 7, start switch Waiting LED 19 for notifying that the weight is in a state of waiting for the start of rotation of the reels 2L, 2C, 2R since a certain period of time has not elapsed since the start of the previous game, after the replay winning Replay to inform you that you are in a replay game LED20 is provided in.

  When playing a game in the slot machine 1, first, a predetermined number of bets (for example, 3) are set by inserting medals into the medal insertion unit 4 or operating the MAXBET switch 6. As a result, the winning line LN becomes valid, the operation to the start switch 7 becomes valid, and the game can be started. If medals are inserted with the bet number set, the amount is added to the credit.

  The winning line is a line for determining whether a combination of symbols displayed on the see-through windows 3 of the reels 2L to 2R is a winning symbol combination. In the present embodiment, an example in which only one winning line LN is provided will be described. However, a plurality of winning lines may be provided. In addition, invalid lines LM1 to LM4 are provided to make it easy to recognize that the combination of symbols constituting the winning line is aligned with the winning line LN. The invalid lines LM1 to LM4 are not determined as winning lines, but when a combination of specific winning symbols (so-called disparity) is aligned on the winning line LN, any of the invalid lines LM1 to LM4 has a predetermined symbol. By aligning the combinations (for example, bell-bell-bell), it is easy to recognize that a combination of symbols constituting a specific prize is arranged on the winning line LN.

  When the start switch 7 is operated in a state where the game can be started, the reels 2L to 2R are rotated to display the symbols variably, and when the stop switches 8L to 8R are operated, the rotation of the corresponding reel is stopped. The three symbols are derived and displayed as display results on the upper, middle, and lower stages of the fluoroscopic window 3. When a combination of winning symbols stops on the winning line LN and a winning occurs, a predetermined number of medals are given to the player according to the winning and the credit is added or the credit reaches the upper limit (50). In this case, medals are paid out from the medal payout exit 9.

  FIG. 3 is a view showing the internal structure of the slot machine 1. FIG. 4 is a diagram illustrating a functional configuration example of the slot machine 1. In the example of FIG. 4, a game control board 40 that controls the progress of the game and outputs various commands according to the progress of the game, an effect control board 90 that controls a predetermined effect according to the command, and a drive power source for the electrical components A power supply board 101 for generating a signal and an external output board 1000 for outputting a signal according to the progress of the game to the outside are provided.

  The game control board 40 advances the game based on detection signals from switches such as various operation means and detection means (illustrated on the left side of the game control board 40 in FIG. 4), and notifies means (game control in FIG. 4). Display devices such as the example on the left side of the substrate 40 are driven and controlled. Further, the game control board 40 drives and controls the reel motors 32L to 32R based on signals from the reel sensors 33L to 33R.

  A circuit configuration (illustrated in the game control board 40 in FIG. 4) such as the main control unit 41 is mounted on the game control board 40. The main control unit 41 performs processing related to the progress of the game, and directly or indirectly controls the configuration mounted on or connected to the game control board 40. The main control unit 41 is a one-chip microcomputer and includes a CPU, a ROM, a RAM, an I / O port, and the like.

  The effect control board 90 is connected to an effect switch 56 and drives and controls an effect device such as the liquid crystal display 51 (illustrated on the left side of the effect control board 90 in FIG. 4). The effect control board 90 is mounted with a circuit configuration such as the sub-control unit 91 (illustrated in the effect control board 90 of FIG. 4). The sub-control unit 91 receives a command transmitted from the game control board 40, performs a process of performing an effect, and directly or indirectly controls a configuration mounted on or connected to the effect control board 90. The sub-control unit 91 is a one-chip microcomputer and includes a CPU, a ROM, a RAM, an I / O port, and the like. The circuit configuration of the sub-control unit 91 includes, for example, a clock device 97 (hereinafter also referred to as RTC) for measuring at least one of date and time. The sub-control unit 91 can execute effect control according to, for example, at least one of the date and time counted by the RTC 97, a detection signal from the effect switch 56, and the like. A hopper motor 34b, various operation means and detection means (illustrated on the right side of the power supply board 101 in FIG. 4) and the like are connected to the power supply board 101.

  FIG. 5 and FIG. 6 are diagrams for explaining the types of winning combinations, symbol combinations of winning combinations, and technical matters related to winning combinations. The name column indicates the name of the winning combination, and the symbol combination column indicates the combination of symbols in which the winning combination becomes a winning. In addition, in the symbol combination column that is aligned with the invalid line, a symbol combination that is easy to be recognized by the player and is a combination of symbols that stop on the invalid line when the winning symbol combination stops on the winning line. Yes. In the payout number column, values (medal payout, replay grant) given at the time of winning are shown. BB1 and BB2 are winning combinations with a transition to an advantageous state of bonus. In the BB1 and BB2 payout number columns, bonus termination conditions to be transferred by winning are shown. Each bonus is terminated when a predetermined termination condition is satisfied. For example, the end condition may be that a predetermined number of medals have been paid out, or the end condition may be that a predetermined game has been consumed.

  In addition, the gaming state column in FIG. 6 shows the gaming state to be transferred when winning. “/” Indicates “or”. For example, for the fall replay of FIG. 6, the symbol combination is “Bell-Replay-Bell”, which is controlled by RT1 at the time of winning, and the value given is a replay grant. In addition, when the symbol combination of the fall replay stops on the winning line, “Replay / Plum-Replay-Replay / Plum” stops on the invalid line. When the special replay symbol combination stops on the winning line, “black BAR / white BAR−black BAR / white BAR−black BAR / white BAR” stops on the invalid line. "Black BAR / White BAR-Black BAR / White BAR-Black BAR / White BAR" can be stopped on the invalid line only when the special replay is won, and when the special replay is not won It is a combination of symbols that is not stopped on the line.

  In addition, the re-playing role (replay) is a role for giving replaying. Here, the re-game refers to a game in which the next game can be performed without using a game value (for example, credit) owned by the player. In other words, the re-game means a game in which the variable display unit can be variably displayed without using the game value owned by the player. In the present embodiment, when a re-game player is won, a prize is won regardless of the operation procedure (at least one of the operation order and operation timing) of the derivation operation means. As a modified example, even if a re-playing winning combination is won, depending on the operating procedure of the derivation operating means, it may be a winning combination (that is, a winning combination).

  FIG. 7 is a diagram showing a symbol combination of the transition outcome. In the transition, the left bells 1 to 4, the middle bells 1 to 4, and the right bells 1 to 4 shown in FIG. If you miss the winning top bell, it will be the same as the winning line LN. When the transition outcome stops on the winning line LN during RT0, 2, 3, and 4, the routine proceeds to RT1.

  FIG. 8 is a diagram for explaining the transition of the gaming state controlled by the main control unit 41, and FIG. 9 is a diagram showing an outline of the gaming state and RT. In the slot machine 1 according to the present embodiment, RT0 to RT5 in which replay is won with a predetermined winning probability (see the numerical value in the replay synthesis probability column in the upper diagram of FIG. 9), and the winning probability of a small role is in RT0 to RT5. Among a plurality of types of gaming states including a bonus that is improved compared to when a game is in progress, the game state is controlled to one of the corresponding game states from when the start condition is satisfied until the end condition is satisfied (along the arrow in FIG. 8). Refer to the winning combination or outcome shown above, see the start condition / end condition column in the upper diagram of FIG. 9).

  When either BB1 or BB2 is won, RT5 control is performed. The winning flag that is set when either BB1 or BB2 wins is carried over until winning of the winning BB occurs. RT5 is also controlled continuously from BB winning to BB winning. During RT5, it is lower than RT0 and RT2, and wins the replay with the same probability as in RT1, RT3 and RT4 (see the numerical value in the replay synthesis probability column in the upper diagram of FIG. 9). Note that the replay probability in RT5 is set to a probability that the payout rate does not exceed 1 even if the winning combination can be won without being missed. In other words, the replay probability in RT5 is the total number of medals to be paid out when a winning combination is not missed during RT5. The total number of medals is not exceeded and the probability that the medals will not increase is set. After winning BB1 and controlling to RT5, when a BB1 winning occurs, the control is controlled to BB1, and a predetermined termination condition is satisfied, so that BB1 ends and RT3 is controlled. Further, after winning BB2 and controlling to RT5, when a BB2 winning occurs, the control is controlled to BB2, and BB2 is terminated when a predetermined termination condition is satisfied, and control is performed to RT4. The types of replays to be internally drawn are determined for each RT type (circles in the lower diagram of FIG. 9 indicate replays to be drawn).

  FIG. 10 and FIG. 11 are diagrams showing combinations of lottery object combinations that are read as lottery object combinations (hereinafter also referred to as winning combinations) for each gaming state. The lottery target role column indicates the name, and the game state column indicates that the lottery target role is a lottery target with a circle for each RT type. For example, the bell is a lottery target combination that is won in any state of RT0 to RT3. The winning probabilities of each lottery target in each state may be set freely in RT0 to RT5 as long as the winning probabilities of the small combination (lottery target other than bonus in FIG. 10) are equal.

  As shown in FIG. 11, the special replay is determined to be a lottery target only when controlled by RT2. Further, in BB1 and BB2, for example, the middle bell is set as a lottery object combination, and it is determined to win with an extremely high probability (for example, 64000/65536). The middle bell is a role that can generate a prize regardless of the operation timing. For this reason, during the bonus, regardless of the operation timing and operation procedure, the middle bell prize can be generated with a very high probability, and the number of medals can be increased efficiently. For this reason, the bonus is an advantageous state for the player.

  FIG. 12 is a diagram illustrating combinations of winning combinations included in a lottery target combination. For example, the weak cherry is the lower cherry. The weak watermelon includes a right-down watermelon, an upper watermelon, and a middle watermelon. Therefore, when the weak watermelon is won in the internal lottery, it means that the right-down watermelon, the upper watermelon, and the middle watermelon are won.

  Among the lottery target combinations, bonus 1 to bonus 12 are combinations that can be won by simultaneously reading out a predetermined winning combination such as BB1 or BB2 and weak cherry or bell. For bonus 1 to bonus 12, different values are determined as the number of determination values, which is a numerical value related to the winning probability. For this reason, the bonus 6 or 12 is the advantage for the player, that is, the ratio of BB1 or BB2 actually winning simultaneously when winning the simultaneous winning combination (hereinafter also referred to as reliability). The number of determination values is determined so that the middle cherries are the highest, followed by strong cherries, strong watermelons, weak cherries, and weak watermelons in this order, and the bell (hereinafter also referred to as the middle tier bell) is the lowest.

  13 and 14 are diagrams for explaining reel control when a plurality of winning combinations are simultaneously won. When a winning operation is performed in the pressing order shown in the pressing order column for each selected lottery target, the reel control is performed to stop the winning combination symbol combination shown in the symbol combination to be stopped to the winning line LN. For example, when the replay GR1 is won, the promotion replay 1 is derived when the pressing order is left middle right, and the normal replay is derived when the pressing order is other than left middle right. Also, for example, when the left bell is elected, if the pushing order is the first left stop, the lower right bell is derived, and if the pushing order is other than the first left stop, the upper bell or the transition start Is derived.

  Further, when winning the simultaneous winning combination, reel control different from that when not winning the simultaneous winning combination can be performed. For example, when a weak watermelon is won, reel control is performed so that a watermelon that falls to the right or an upper watermelon is prioritized over a middle watermelon, but is pulled to the winning line, while a right watermelon is lowered when a strong watermelon is won. Reel control is performed in which the middle-stage watermelon is given priority over both the watermelon and the upper-stage watermelon to be drawn onto the winning line. When a weak cherry or a strong cherry is won, reel control is performed to draw the lower cherries onto the winning line, and when a middle cherry is selected, reel control is performed to pull the middle cherries onto the winning line. . As a result, it is possible to estimate whether it is cherry or watermelon, weak or strong, or mid-stage cherry from the combination of symbols when the reels 2L to 2R are stopped, and the expectation for bonus winning or AT winning is different. Can be made.

  In the narrow sense, “game” in the slot machine 1 refers to a period from when the start switch 7 is operated to when the reels 2L to 2R are stopped. Since the medals are paid out and the game state is shifted after the reels 2L to 2R are stopped, these incidental processes are also included in the “game” in a broad sense.

  In the slot machine 1 according to the present embodiment, the medal payout rate changes according to the set value. Specifically, the medal payout rate is changed by determining a winning probability used in an internal lottery described later according to the set value. The fact that the winning probability changes according to the set value is referred to as a setting difference, and the fact that the winning probability does not change according to the set value is also referred to as no set difference. The set value is composed of 6 levels of 1 to 6, with 6 being the highest payout rate and the payout rate being lower as the value is decreased in the order of 5, 4, 3, 2, 1. That is, when 6 is set as the set value, the advantage is highest for the player, and as the value decreases in order of 5, 4, 3, 2, 1, the advantage decreases stepwise. However, out of a plurality of types of lottery target roles, a section having a high degree of advantage for the player (a high probability state of AT lottery called CZ and a state where a net increase in the number of ATs to be described later increases), etc. There is no setting difference in the lottery target combination that is the target of the advantageous section operation lottery that determines whether or not to shift. On the other hand, among a plurality of types of lottery object combinations, lottery object combinations that are not eligible for advantageous section operation lottery may have a setting difference. In order to change the setting value, an administrator may operate an operation unit (not shown) provided in the slot machine 1 to shift to a setting change state in which the setting value can be changed. In order to confirm the set value, the administrator may perform a predetermined operation to shift to a setting confirmation state in which the set value can be confirmed.

  In addition, the winning probability of the internal lottery is changed according to the setting value setting, the winning probability of the advantageous section operation lottery is changed according to the setting value setting, and the internal lottery winning is determined according to the setting value setting. Any one of changing the probability and changing the winning probability of the advantageous section operation lottery may be performed.

[Game processing]
The main control unit 41 performs a game control process to control one game. In the game control process, first, a BET process for setting a bet amount and performing a credit settlement / a bet settlement is performed.

  When the start switch 7 is operated after setting the betting amount, a random number value is extracted from a predetermined random number circuit, and it is determined (internal lottery) whether or not a winning is allowed based on the extracted random number value. The internal lottery process (see FIGS. 10 to 12 and the like) is performed. The random number circuit updates a numerical value within a predetermined numerical value range (0 to 65535) according to a predetermined update rule. The main control unit 41 extracts a numerical value updated by the random number circuit when the start switch 7 is operated as a random value. When a lottery target combination is won in the internal lottery, a winning combination winning flag included in the lottery target combination is set in a predetermined area of the RAM. For example, when BB1 is won, a BB1 winning flag is set, and when a strong cherry is won, a winning flag for the lower cherries and a winning flag for a single piece are set. The winning flags of BB1 and BB2 are carried over until the winning BB is won, while the winning flags corresponding to winning combinations other than BB1 and BB2 are determined when the winning game ends regardless of whether or not a winning has occurred. Will be erased.

  When the internal lottery process ends, a reel rotation process is performed. In the reel rotation process, after a predetermined time (for example, 4.1 seconds) has elapsed from the start of reel rotation in the previous game, after the reels 2L to 2R start to rotate, the stop switches 8L to 8R are activated. And the rotation of the reel is stopped according to the stop operation (see FIGS. 13 and 14). In the reel rotation process, in order to execute a freeze effect that delays the progress of the game for a predetermined period (delays the activation of the stop operation of each of the stop switches 8L to 8R) when a predetermined freeze condition is satisfied. After executing the freeze effect processing, the stop switches 8L to 8R are validated to shift to the normal game.

  When the reels 2L to 2R are stopped and the reel rotation process is completed, a winning determination process (see FIGS. 5 to 7 and the like) is performed for determining whether or not a winning has occurred based on the symbol combination on the winning line. . Further, the state shown in FIG. 8 is controlled according to the symbol combination on the winning line.

  When the winning determination process ends, a payout process is performed. In the payout process, medals are paid out or credits are added according to the occurrence of a prize, various processes not related to the prize (for example, the process related to the bonus end control by counting the number of medals paid out in the bonus, and the winning without carryover) Flags (deletion of a winning combination such as a small combination / replaying combination) are performed. Further, when it is determined that either BB1 or BB2 has been won, the winning flag of the winning BB is erased. In the game end process, a process for setting a gaming state in preparation for the next game (see FIG. 8, FIG. 9, etc.) is executed. Thereby, the game control process for one game is completed, and the game control process for the next one game is started.

[About AT]
The main control unit 41 can be controlled to AT (assist time) in addition to advantageous states such as bonus and RT2. The main control unit 41 executes an AT lottery to determine whether or not to control by the AT. Further, the main control unit 41 can specify an operation procedure (push order) for stopping the symbol combination advantageous to the player on the winning line LN when it is determined that the AT is controlled by the AT lottery. A process for executing a navigating effect is executed.

  During non-AT, the main control unit 41 performs AT lottery processing for determining whether or not to control to AT when a predetermined AT lottery condition is satisfied. The main control unit 41 controls the AT by performing AT control processing when the AT lottery is won in the AT lottery. The main control unit 41, when it is determined to be controlled by the AT, when the predetermined AT addition lottery opportunity is established, the AT addition lottery for lottering whether or not to extend the control period to the AT Execute. The main control unit 41 determines whether or not to extend the period controlled by the AT in the AT extra lottery process, and the period to extend.

  When executing the AT lottery process, the main control unit 41 transmits an AT lottery command that can specify the information determined during the AT lottery process to the sub-control unit 91. The sub-control unit 91 performs a winning suggestion effect that suggests that the AT has been won based on the AT lottery command. In the AT control process, the main control unit 41 transmits, to the sub-control unit 91, a push order command that can specify an operation procedure (also referred to as a correct procedure) for stopping a symbol combination that is advantageous to the player. During the AT, the sub-control unit 91 executes a navigation effect that can specify a pressing order for stopping a symbol combination advantageous to the player on the winning line LN when receiving a pressing order command. For this reason, a player becomes advantageous by being controlled by AT. Advantageous symbol combinations include the so-called left-down bell or middle bell at the time of winning the so-called push order bell, such as the left bell 1-4, middle bell 1-4, and right bell 1-4 in FIG. 14, the replay in FIG. Promotion replay at the time of winning GR1 to replay GR6, normal replay at the time of winning replay GR11 to replay GR13, and special replay at the time of winning replay GR21 to replay GR23 are included.

[Processing related to AT of sub-control unit 91]
When the sub-control unit 91 receives the AT lottery command, the sub-control unit 91 performs the winning suggestion effect lottery to determine that the winning suggestion effect is to be executed and its type. As the winning suggestion effect, for example, an effect of displaying a predetermined image on the liquid crystal display 51 is provided. The effects for displaying the predetermined image include, for example, a character A effect, a character B effect, a button effect, a continuous hit effect, and the like. Such an effect of displaying a predetermined image is performed together with a control for outputting a predetermined sound effect from the speakers 53 and 54 and a control for lighting the effect effect LED 52 and the reel LED 55. Note that any one of the controls may be performed alone, or may be performed in a combination of two or more (for example, a predetermined image and sound are executed and the LED is not turned on). .

  The character A effect is an effect of displaying the character A. The character B effect is an effect for displaying the character B. The button effect is an effect of displaying a button image to prompt an operation to the effect switch 56 and displaying a predetermined image that suggests the reliability of BB winning or AT winning according to the operation to the effect switch 56. . The struck-up effect is BB winning by urging repeated operation to the effect switch 56, increasing a predetermined meter image according to the repeated operation to the effect switch 56 within a predetermined operation period, and reaching MAX. Or it is an effect that suggests that you have won the AT.

  The sub-control unit 91 has a winning suggestion effect at different ratios depending on whether BB winning and AT winning, only BB winning or AT winning, or whether BB winning or AT winning is done. The winning suggestion effect lottery process for determining whether or not to execute and the type of the winning suggestion effect to be executed is executed.

  In the winning suggestion effect lottery process, it is determined that at least BB winning or AT winning is determined to execute the winning suggesting effect, and even if BB winning or AT winning is not performed, the winning suggestion effect is executed at a predetermined rate. decide. The predetermined ratio is set to a higher ratio, for example, in the case of a small winning combination with high BB winning reliability. Thereby, the winning suggestion effect is executed not only when the BB winning or the AT winning is performed but also when the BB winning or the AT winning is not performed.

  Also, in the winning suggestion effect lottery process, when it is determined that the winning suggestion effect is to be executed, the type of the winning suggestion effect is determined at a different ratio depending on at least whether the BB winning or AT winning is won. Specifically, it is an advantage for the player, and when it is executed, the reliability of BB winning or AT winning is in the order of consecutive hit effect, button effect, and character B effect, and the character A effect is the lowest. Thus, the ratio is determined so that the type of winning suggestion effect is determined. The effect to be executed is not limited to one in which one winning suggestion effect is determined, and a plurality of winning suggestion effects may be determined.

  The sub-control unit 91 specifies that a lottery subject belonging to a specific group has been won, that an AT has been won, whether or not an AT has been won or not, the number of AT games, and AT start timing, using an internal winning command and AT lottery command To do. The predetermined timing for executing the winning suggestion effect is a game before the AT start timing determined by a lottery of the timing for starting AT (a lottery for starting AT after 0 to 32 games have elapsed since the AT winning game). For example, if it is determined that the AT start timing is after 0 games, a winning suggestion effect is executed for the game (AT winning is notified in the AT winning game). Further, if it is determined that the AT start timing is after 32 games have elapsed, a sign effect (effect that wins AT win) is executed for 31 games, a win suggestion effect is executed on the 32nd game, and AT win is notified.

  Here, even when the sub-control unit 91 specifies that the AT has not been won by an AT lottery command, the sub-control unit 91 executes a winning suggestion effect (an effect for notifying that the AT is not winning) as a gaze effect. For example, the sub-control unit 91 can win a lottery target belonging to a specific group by an internal winning command, and can specify that the AT is not won by an AT lottery command. The main control unit 41 has not yet decided. In such a case, the sub-control unit 91 performs a lottery of the number of games for executing the winning selection suggestion effect from 0 to 32 games, and determines the number of games for the winning selection suggestion effect.

  When the sub-control unit 91 wins the winning suggestion effect lottery, it executes a winning suggestion effect according to the results of the BB lottery / AT lottery at the start of the next game, and then notifies the results of the BB lottery and the AT lottery.

  As a result of the BB lottery and AT lottery, when both are not won, an effect of displaying a message such as “Sorry!” On the liquid crystal display 51 is executed, and when BB is won, a message such as “BB confirmed!” Is displayed on the liquid crystal display 51, and when the AT is won, a message that can specify the number of AT games acquired such as “100 games acquired!” Is displayed along with the message “AT confirmed!” The number of AT games acquired such as “AT over 100 games after the end of BB!” Can be specified together with the message “BB / AT confirmed!” An effect of displaying a message on the liquid crystal display 51 is executed. Note that, when a BB win is made in a game in which BB is won, the sub-control unit 91 does not execute a winning suggestion effect for informing the BB winning.

  Further, the sub-control unit 91 calculates the number of AT games acquired by AT winning or extra winning by calculating not only the number of AT games but also the number of AT games at the previous reception based on the AT game number command. Identifies and executes the suggestion effect.

[About various commands]
The main control unit 41 transmits to the sub-control unit 91 a command that can specify the progress of the game and the processing result according to the execution of the processing exemplified above. The sub control unit 91 performs various processes based on commands from the main control unit 41.

  In this embodiment, the main control unit 41 sends an internal winning command, a push order command, a stop switch or start switch operation command, a gaming state command, an AT lottery command, an AT command, an AT period to the sub control unit 91. A plurality of types of commands including a command, a CZ lottery command, a stock command, a CZ in-progress command, and a freeze command are transmitted.

  The internal winning command is a command that can specify the group to which the lottery object combination that has been won according to the result of the internal lottery belongs. The internal winning command is transmitted when the start switch 7 is operated and the game is started. By receiving the internal winning command, the sub-control unit 91 can specify the operation of the start switch 7 and the group to which the winning lottery combination belongs.

  The push order command is a command that can specify an operation procedure (also referred to as a correct answer procedure) for stopping a symbol combination that is advantageous to the player in accordance with the lottery object winning combination in the internal lottery. The push order command is transmitted when the start switch 7 is operated and the game is started. In the present embodiment, a push order command that can specify the correct procedure is transmitted during AT, whereas no push order command is transmitted during non-AT. For this reason, the sub-control unit 91 can identify the correct procedure by receiving the push order command during AT, but cannot identify the correct procedure during non-AT. The main control unit 41 does not transmit a push order command that can specify the correct procedure during non-AT, and specifies a push order command that cannot specify the correct procedure (for example, a common procedure regardless of the winning combination). Possible push order commands) may be sent.

  The operation command for the stop switch or start switch is a command indicating that the stop switch or start switch has been operated, and is transmitted at each operation. The gaming state command is transmitted when the gaming state transitions. Specifically, it is transmitted when RT shifts or is controlled by a bonus.

  The AT lottery command is a command that is transmitted when the AT lottery is performed, and can specify whether or not the AT lottery has been won, the period for which the AT is controlled, the AT start timing, and the like.

  The AT command is a command that is transmitted when the game is started, and can specify whether or not the game is an AT game. For example, if control to the AT by the AT control process is not executed even if it is determined to be controlled by the AT, a command capable of specifying a non-AT is transmitted, and it is determined to control to the AT and When the AT is controlled by the AT control process, a command capable of specifying the AT is transmitted.

  The AT period command is a command that can specify an AT period that is a period controlled by the AT managed by the main control unit 41, and is transmitted when the game starts. For example, when the AT is controlled over a period of 100 games, a command capable of specifying 100 is transmitted.

  The CZ lottery command is a command that is transmitted when a lottery is performed to determine whether or not to control to the CZ that wins the AT lottery with a high probability. This command can specify the start timing. In the present embodiment, a period from winning a CZ to starting CZ is defined as a stock period, and a CZ game, which is a right related to AT lottery, is granted during the stock period. The stock command is information that can specify the stock period and the number of CZ games accumulated during the stock period, and is transmitted every game during the stock period.

  The command during CZ is a command transmitted every game while being controlled by CZ, and is information that can specify that the number of CZ games and CZ is controlled. The freeze command is a command transmitted when executing the freeze effect, and is information that can specify the period during which the game progress is delayed and the type of the freeze effect to be executed.

[Game flow]
Here, referring to FIGS. 8 and 9 again, the flow of the game will be described together. First, the flow of the game in RT0 to RT4 other than RT5 and bonus will be described. In RT0 to RT4, the game flows as described below depending on whether or not AT is in progress. First, the flow of a game during non-AT will be described.

  After the setting change state is finished or after BB1 is finished, it is controlled by RT3. It becomes non-AT by being controlled to the setting change state, and also becomes non-AT even when the AT lottery is not won at the end of BB1. In such a case, the RT 3 is not controlled by the AT and the navigation effect is not executed. As described above, since the navigation effect is not executed in RT3, if one of the bells such as the left bells 1 to 4 is won in RT3, the transition start may occur depending on the timing of the second stop and the third stop. Is derived (see FIG. 14). In addition, when the replays GR11 to 13 are selected, depending on the pressing order, a fall replay is won (see FIG. 14). Transition to RT1 is made by deriving the transition outcome or winning the fall replay.

  Also, after BB2 is finished, it is controlled to RT4. If the AT lottery is not won at the end of BB2, it will be non-AT and will not be controlled by AT in RT4, and no navigation effect will be executed, so any of the bells such as left bells 1-4 in RT4 When winning is made, the transition outcome is derived depending on the timing of the second stop and the third stop (see FIG. 14). In addition, when the replays GR11 to GR13 are won, depending on the pressing order, a fall replay is won (see FIG. 14). Transition to RT1 is made by deriving the transition outcome or winning the fall replay.

  In RT1, the game proceeds to RT0 by winning the promotion replay. In order to win the promotion replay, as shown in FIG. 13, it is necessary to stop the operation procedure for winning one of the replays GR1 to GR6 and making the promotion lip winning.

  Even when controlled to RT0, it is set so that it is difficult to maintain control to RT0. That is, as shown in FIG. 11 and FIG. 13, there is a possibility that the replays GR11 to 13 will be won at RT0. At this time, the fall replay wins with a probability of 2/3 and falls to RT1.

  Furthermore, when one of the bells such as the left bells 1 to 4 is won at RT0, all but the predetermined reel (the right-down bell shown in FIG. 14 or the reel for winning the middle bell) is stopped for the first time. Sometimes, the transition outcome is derived depending on the timing of the second stop and the third stop. In addition, when the replays GR11 to GR13 are won, depending on the pressing order, a fall replay is won (see FIG. 13). The transition is made to RT1 by deriving the transition outcome or winning the fall replay. Further, as shown in FIGS. 11 and 13, in RT0, there is a possibility that the replays GR21 to 23 will be won. At this time, a predetermined reel (reel for winning the special replay shown in FIG. 13) is selected. When it stops for the first time, there is a possibility that the special replay wins and is controlled by RT2. However, even when controlled by RT2, when one of the bells such as the left bell 1 to 4 is won, the reels other than the predetermined reel (reel for lowering the right lowering bell or middle bell shown in FIG. 14) are selected. When the first stop is performed, the transition outcome is derived depending on the timing of the second stop and the third stop. Further, when controlled by RT2, if the replays GR11 to GR13 are won, depending on the pressing order, a fall replay is won (see FIG. 13). The transition is made to RT1 by deriving the transition outcome or winning the fall replay. As a result, most of the games during non-AT are digested at RT1.

  Next, the flow of the game during the AT will be described. In RT1, when one of the replays GR1 to GR6 is won, a navigation effect for specifying an operation procedure for winning a promotion replay can be executed. Therefore, by performing a stop operation according to the navigation effect, it is possible to shift to RT0 by winning the promotion replay. In RT0, when any one of the replays GR11 to 13 is won, a navigation effect for specifying an operation procedure for winning a normal replay can be executed. For this reason, RT0 can be maintained by normal replay winning by performing stop operation according to a navigation effect. In addition, in RT0, when one of the left bell 1 to 4, the middle bell 1 to 4, and the right bell 1 to 4 is won, the operation procedure for winning the right falling bell or the middle bell is specified. The navigation effect is executed. Therefore, by performing the stop operation according to the navigation effect, it is possible to avoid derivation of the transition outcome and maintain RT0. Furthermore, in RT0, when any of the replays GR21 to GR23 is won, a navigation effect for specifying an operation procedure for winning a special replay can be executed. For this reason, by performing a stop operation according to the navigation effect, it is possible to shift to RT2 by special replay winning.

  In RT2, when one of the left bell 1 to 4, the middle bell 1 to 4, and the right bell 1 to 4 is won, the navigation for specifying the operation procedure for winning the right falling bell or the middle bell Production is performed. For this reason, by performing the stop operation according to the navigation effect, it is possible to avoid the derivation of the transition outcome and maintain RT2. In RT2, when any of the replays GR11 to 13 is selected, a navigation effect for specifying an operation procedure for winning a normal replay can be executed. For this reason, RT2 can be maintained by a normal replay winning by performing a stop operation according to the navigation effect.

  As described above, in the slot machine 1 according to the present embodiment, when the AT is in progress, the navigation effect is executed so that the RT2 is controlled and the RT2 is maintained. Most of the games will be digested at RT2. The AT ends when the number of AT games becomes zero. The number of AT games is controlled to be RT2 + AT (in this embodiment, the state controlled by AT in RT2 advantageous to the player is particularly referred to as assist replay time (hereinafter referred to as ART)). Counting is started from the next game after the game that has become possible, that is, the game after winning one of the replays GR21 to 23 at RT0 and winning special replay. As a result, when the game for the number of AT games is substantially digested by ART, AT ends. Then, ART ends when AT ends.

  After the ART is finished, the navigation effect is not executed, but the control to the RT2 is maintained until a transition outcome is derived or until a fall replay is won. However, during RT2 after the end of ART, since it is non-AT, the first reels other than the predetermined reel (reel for lowering the right bell or middle bell shown in FIG. 14) are first stopped as described above. When the time is reached, the transition outcome is derived depending on the timing of the second stop and the third stop. In addition, when controlled by RT2, if the replays GR11 to GR13 are won, a fall replay wins depending on the pressing order. As a result, during RT2 after the ART is finished, the transition is stopped at an extremely early stage after the ART is finished, or a transition to RT1 is made when a fall replay wins.

  Next, the flow of the game after winning BB1 or BB2 will be described. Regardless of which RT is controlled, when BB1 or BB2 is won, control is performed to RT5 as shown in FIG. Further, in the next game after the end of the BB winning game, a winning suggestion effect is executed to notify that BB has been won, and the player can grasp that BB1 or BB2 has been won. When a BB1 winning occurs, the process proceeds to BB1, and when a predetermined end condition (for example, paying out a predetermined number of medals, elapse of a predetermined number of games, or the like) is satisfied, the process proceeds to RT3. Further, when a BB2 winning occurs, the process proceeds to BB2, and ends when a predetermined end condition (for example, paying out a predetermined number of medals, elapse of a predetermined number of games, etc.) is satisfied, and then proceeds to RT4. The Here, when the BB is simultaneously won with another lottery target combination, reel control is performed so that the lottery target combinations other than the BB win a prize. For this reason, when the probability of winning a small combination or re-playing combination in RT4 is high, it is difficult for a BB winning to occur and it is difficult to shift to a bonus. Therefore, in RT4, the probability of winning the re-gamer is set to be lower than RT0 or RT2 (see FIG. 9). Furthermore, in RT0 to RT5, the probability of winning a small combination that is a lottery target combination other than the re-game combination is set so as not to change. Therefore, in RT4, it is set so that it is easy to win the BB alone and it is difficult for the player to shift to the bonus forever.

[About AT lottery processing]
The main control unit 41 performs an AT lottery process for determining whether to control to the AT when a predetermined AT lottery condition is satisfied. The main control unit 41 can control the CZ (chance zone) to win the AT lottery with a high probability, and performs the AT lottery with different probabilities based on whether or not the CZ is in progress. Specifically, AT lottery is executed using the AT lottery table shown in FIG. Non-CZ in the table indicates a state that is not CZ. In the table, “/” means “or”, and “middle cherry, strong cherry, strong watermelon, weak cherry, weak watermelon” is a drawing target role in FIG. “Less” means that none of the lottery roles was won. For example, if the middle stage cherry is won during non-CZ, the AT lottery is won with a probability of 30%. On the other hand, if the middle cherries are won during CZ, the AT lottery is won with a probability of 80%. In addition, if none of the lottery eligible roles is won during the non-CZ (outside), the AT lottery is not won, but if no lottery eligible role is won during the CZ, there is a 5% probability. Win the AT lottery. That is, the game in the CZ is an advantageous game that wins the AT lottery with a higher probability than the game in the non-CZ.

[Flow until AT is controlled]
The flow from the non-CZ control to the AT control in the first embodiment will be described with reference to FIG. The route from non-CZ to AT transitions to the AT lottery during non-CZ and directly transitions from non-CZ to AT, and after winning the CZ lottery during non-CZ and transitions to CZ, There is a route to win the AT lottery and move to AT during CZ. In the following, a route that moves to the AT via the CZ will be described.

  The main control unit 41 performs CZ lottery processing for determining whether to control to CZ when the CZ lottery target combination is won twice or more continuously during non-CZ. The CZ lottery process may be executed after the internal lottery is performed in the internal lottery process, for example, as long as it is executed at a predetermined timing in the progress of one game. In addition, the CZ lottery target combination in the present embodiment is the replay shown in FIG. 11, the middle cherry, the strong cherry, the weak cherry, the strong watermelon, or the weak watermelon shown in FIG. Winning a CZ lottery for two or more consecutive wins means winning two consecutive replays, winning the middle cherries in the next game winning the replay, or winning the middle cherries in the next game Including winning a strong cherry.

  When the main control unit 41 wins the CZ lottery, the main control unit 41 determines the number of CZ games, which is a period to be controlled by CZ, as 1, and stores the number of CZ games in a predetermined area of the RAM. Thereafter, the main control unit 41 determines the timing for starting CZ by lottery. The period from winning the CZ lottery to starting the CZ is a stock period, and the main control unit 41 gives the number of CZ games if the CZ lottery target role is won twice or more consecutively during the stock period. The CZ addition lottery of whether or not to do is performed. When the CZ addition lottery is won, 1 is added to the number of CZ games stored in a predetermined area of the RAM and stored.

  When the stock period elapses, it is controlled to CZ. The main control unit 41 performs CZ control processing according to the number of CZ games stored in a predetermined area of the RAM, and controls to CZ. Specifically, when the number of CZ games is 3, it is controlled to CZ over 3 games. If the AT lottery is won during CZ, it will not shift to AT until the number of CZ games reaches 0, and if the AT extra lottery opportunity is established, whether or not to extend the control period to AT Execute AT onboard lottery. Thereafter, the number of CZ games is 0, and when the AT lottery is won, the game is controlled to AT, and when the AT lottery is not won, the game is controlled to non-CZ.

[CZ lottery and stock period]
The CZ lottery and the stock period will be described with reference to FIG. As shown in FIG. 17A, the winning probability of the CZ lottery is set so as to differ depending on the number of times the CZ lottery target combination is won. The main control unit 41 counts and stores the number of wins in a predetermined area of the RAM every time a CZ lottery target combination is won. The stored number of wins is reset when winning a lottery subject other than the CZ lottery subject or when winning the CZ lottery and becomes 0. Further, the CZ lottery table shown in FIG. 17A is also used in the CZ extra lottery. During the stock period, the winning count of the CZ lottery target combination is reset when the CZ winning lottery is won or when the CZ lottery is entered, and becomes 0 times. The CZ lottery and the CZ extra lottery are performed using the same CZ lottery table regardless of the gaming state. Therefore, it is easier to win the CZ lottery or the CZ extra lottery when the winning probability of the CZ lottery target role is higher, and the CZ game is more likely to be awarded. Since the CZ lottery target combination is mainly composed of the replay combination, the CZ game is more likely to be awarded in the state where the replay probability is higher than in the lower state. In addition, although the number of times that the CZ lottery target combination is won continuously is reset when the CZ lottery is won, it may not be reset. Specifically, when the CZ lottery is won in the game immediately after winning the CZ lottery when the CZ lottery is won in response to winning the CZ lottery target twice consecutively, Alternatively, the CZ lottery may be performed on the assumption that the CZ lottery target combination is won three times in succession.

  The main control unit 41 sets the stock period when the CZ lottery is won. As shown in FIG. 17B, the stock period is set so that the stock period becomes longer in the second state in which the CZ game is more easily given than in the first state with a higher probability than in the first state. .

[Directing during the stock period]
The effects during the stock period will be described with reference to FIG. Here, in FIG. 18A, the effect switch 56 filled with the diagonally downward slanting line drawn under the right-pointing arrow indicates that the effect switch 56 has been operated. In addition, a diagonally downward diagonal line in FIG. 18B indicates that light is emitted in red.

  As shown in FIG. 18 (A), during the stock period, a character image “chance” is displayed on the lower right of the liquid crystal display 51 so that the player can know that the stock period is in progress. It has become. In addition, during the stock period, the effect switch 56 is lit to urge the operation of the effect switch 56. When the effect switch 56 is operated, the display is switched from the display of “chance” to the display of the stock period and the number of rights stocked. Below the character image “Game”, the number of remaining games is displayed. Further, the number of CZ games accumulated during the stock period is displayed as the number of stars below the character image “Stock” displayed on the right side of “Game”. Specifically, in FIG. 18A, the remaining stock period is 5 games and the number of CZ games is 3 games. As shown in FIG. 18B, the display method for indicating the stock period differs depending on whether the current state is the first state or the second state. Specifically, the second state is displayed in a manner in which the stock period is emphasized compared to the first state. The operation of the effect switch 56 may be performed at any time during the stock period, or may be performed only when the reel 2 is stopped during the stock period.

  The effect during the stock period displayed on the liquid crystal display 51 is controlled by the sub control unit 91 based on the stock command transmitted from the main control unit 41. Specifically, during the stock period, the main control unit 41 transmits a stock command for each game as information that can specify the remaining stock period and the number of CZ games. The sub-control unit 91 executes the effects during the stock period based on the stock command transmitted from the main control unit 41 and the gaming state command. It is determined in advance which gaming state each of the first state and the second state corresponds to, and the sub-control unit 91 determines which one of the first state and the second state based on the gaming state command. Whether the state is controlled can be determined.

  When the sub-control unit 91 receives the stock command, the sub-control unit 91 causes the liquid crystal display 51 to display a character image “chanced” and to the effect switch 56 while the character image “chanced” is displayed. Is detected, the stock period and the number of CZ games are switched to a display that can be specified.

  In the present embodiment, the display is switched when the production switch 56 is operated. However, when a stock command is received, the “chance” is set so that images relating to the stock period and the number of CZ games are not visible. May be displayed in an overlapping manner, and when the operation on the effect switch 56 is detected, the character image “chance” is erased so that the image relating to the stock period and the accumulated amount can be visually recognized. In addition, a character image “chance” may be displayed when a predetermined period of time has elapsed since the operation on the effect switch 56 is detected, and when an operation on the effect switch 56 is detected again, A character image “medium” may be displayed.

  Further, when the CZ lottery is performed, the main control unit 41 transmits a CZ lottery command as information that can specify the result of the CZ lottery. Based on the CZ lottery command, the sub-control unit 91 may execute an effect suggesting whether or not the CZ lottery has been won and whether or not the stock period is set. Specifically, in the game in which the CZ lottery is performed, an operation for starting the next game after the game in which the CZ lottery is performed is performed after “??” is displayed in the area where the stock period is displayed. Or at the end of the game in which the CZ lottery was performed, the display of “??” may be switched to the display of the CZ lottery result. As the display of the CZ lottery result, the set stock period is displayed when the winner is won, and the character image “sorry” is displayed when the winner is not selected. If it is not won, nothing may be displayed.

[Production in CZ state]
The effect during CZ is demonstrated using FIG. Freeze effect is executed during CZ. The freeze effect is an effect that delays the progress of the game over a predetermined period (delaying the activation of the stop operation of each of the stop switches 8L to 8R). The freeze effect in the CZ state is executed after t2 elapses after the start switch 7 is operated. All the reels 2 rotate at the timing when the start switch 7 is operated. The operation of each of the reels 2L to 2R is temporarily stopped so that a specific symbol (cherry in FIG. 19) is derived on the active line at the timing when t1 has elapsed since the start switch 7 was operated. After the reels are temporarily stopped for a period of time that can be recognized as being derived and displayed by the player, all the reels 2 are rotated again, and at the timing t2 after the start switch 7 is operated, the stop switch Operation to 8 is enabled.

  When the stock period is 0 game and the number of CZ games is 1 or more, the main control unit 41 controls the CZ state and determines whether to execute a freeze effect. The main control unit 41 always performs a freeze effect when the AT lottery is won when the AT lottery is performed when the winning lottery is won (except when the AT lottery is performed when the winning combination is triggered). When the AT lottery is not won, it is determined that the freeze effect is performed with a predetermined probability. Moreover, the main control part 41 determines as the effect which makes the symbol regarding the lottery object role which became AT lottery opportunity temporarily stop to an active line as a freeze production. For example, when an AT lottery is performed by winning the middle stage cherry and it is determined that the freeze effect is to be executed, the cherry pattern is temporarily stopped so that the cherry symbols are aligned with the active line. Therefore, as shown in FIG. 19, the cherry symbol is temporarily stopped at the middle stage, so that it can be suggested to the player that the AT lottery has been performed. When the main control unit 41 determines to perform the freeze effect, the main control unit 41 performs the freeze effect process in the reel rotation process. When executing the freeze effect, the main control unit 41 transmits to the sub-control unit 91 a freeze command that can specify the period for delaying the progress of the game and the type of freeze effect to be executed. The sub-control unit 91 executes an effect corresponding to the freeze effect using the liquid crystal display 51 based on the freeze command.

[Main effects of the first embodiment]
Next, main effects obtained by the first embodiment will be described.

  (1) As shown in FIGS. 15 to 17, when being controlled to the second state, the CZ game is more easily given than when being controlled to the first state, and the CZ game is given. The stock period tends to be longer than when the stock period is controlled to the first state. Therefore, the player is more advantageous when controlled to the second state than when controlled to the first state.

  (2) Since the display of the remaining stock period is different between the first state and the second state as shown in FIG. 18B, the interest of the game is improved. It is emphasized that the stock period indication is also a suggestion that it is during the stock period, and in the second state that is more advantageous than the first state for the indication, it is a stock period rather than the first state. Since the effect is executed, the player can expect that the effect in which the stock period is emphasized is executed, and the interest of the game is improved.

  (3) As shown in FIG. 18A, the number of CZ games is displayed such that the greater the number of games, the greater the number of stars. That is, the effect related to the number of CZ games changes to an effect mode in which the number of games is emphasized as the number of games increases. Therefore, the player can confirm the total number of CZ games assigned based on the effect mode.

[Second Embodiment]
In the second embodiment, a case will be described where RT1 in the first embodiment described above is set to the “first state”, RT0 is set to the “second state”, and RT2 is set to the “third state”. Also, the same configuration / process as in the first embodiment is omitted, and a different configuration / process will be described.

[About CZ]
In the second embodiment, the CZ lottery is performed when the CZ lottery target combination is won twice or more in succession during the non-CZ period and while being controlled by RT0. A CZ lottery is also performed when a non-CZ is in progress and the gaming state has shifted from RT0 to RT1. In addition to the case where the CZ lottery is won twice or more consecutively, the CZ lottery lottery is performed when the gaming state transitions from RT1 to RT0 and when the gaming state transitions from RT0 to RT2. Is called. Further, when the gaming state transitions from RT1 to RT0 and when the gaming state transitions from RT0 to RT2, the CZ lottery and the CZ extra lottery are won with a probability of 100%.

[About stock period]
The stock period of the second embodiment will be described with reference to FIG. In the second embodiment, the stock period can be set only during the period controlled by RT0 to RT2. While controlled by RT1, as in the first embodiment, a CZ lottery is performed in response to winning a CZ lottery target role multiple times, and when the CZ lottery is won, the stock period is determined by lottery. . For example, in RT1, the stock period is determined as one of 1 to 3 games. On the other hand, while it is controlled to RT0 or RT2, it is always controlled as a stock period, and when it shifts to RT1, the stock period ends and it is controlled to CZ. Here, when the stock period is set in RT1, it is controlled to CZ when the set stock period elapses regardless of whether or not the game state has shifted to another game state.

  For example, if the CZ lottery is won at RT1 and 3 games are set as the stock period, the number of CZ games will be incremented by 1 even if the promotion replay is won during 3 games and the game moves to RT0. Stock period does not change. After that, even after winning the CZ lottery and winning the special replay and moving to RT2, the number of CZ games is only incremented by 1 and the stock period remains the same. When the time elapses, the CZ is controlled according to the number of CZ games accumulated during the stock period. In addition, when the control is shifted to RT0 without being won in the CZ lottery while being controlled by RT1, the number of CZ games is given and the stock period is controlled. After that, it is controlled as a stock period until derivation of the transition outcome or winning of the fall replay occurs.

  When the stock period is set in RT1, the process shifts to RT2 or RT3 during the stock period, and when it is controlled to CZ while being controlled by RT2 or RT3, control is performed to extend the number of CZ games. Also good. For example, when a CZ lottery target winning combination is continuously won when controlled by CZ while being controlled by RT2 or RT3, a CZ addition lottery for adding the number of CZ games is as shown in FIG. You may perform using a CZ lottery table. Further, when the stock period is set in RT1, when the transition to RT2 or RT3 is made during the stock period, the stock period is not reset, but the stock period may be reset. For example, since it is always controlled as a stock period during RT2 or RT3, when it shifts from RT1 to RT2, it may be controlled as a stock period until it shifts to RT1.

  The stock period in the second embodiment can be specified while being controlled by RT1, but cannot be specified while being controlled by RT0 or RT2. Therefore, the sub-control unit 91 may display “???” as the display of the stock period when the stock period cannot be specified.

  Each state of the second embodiment will be described with reference to FIG. As shown in FIG. 21A, the left bell 1 to 4, the middle bell 1 to 4, the right bell 1 to 4 shown in FIG. The lottery probability of the push order bell is equally 1/5, and the lottery probability of the replay shown in FIG. 11 is also equal to 1/3. In RT0, when one of the lip GRs 11 to 13 is won with a probability of 1/10, when a fall replay is won according to the order in which the stop switch 8 is operated, or in a push order with a probability of 1/5 In the case of winning the bell, the gaming state shifts to RT1 when no winning combination is won and a transition outcome is derived. On the other hand, in RT2, when one of the lip GRs 11 to 13 is won with a probability of 1/20, when winning the fall replay according to the order of operating the stop switch 8, or 1/5 When a winning order bell is won with a probability, the gaming state shifts to RT1 only when a transition outcome is derived without winning any small role. In RT0 and RT2, the replay probabilities are equal, but the probabilities of winning the rep GR11 to 13 in the replay are different. Therefore, the probability of winning a replay other than the replays GR11 to 13 among the replays is 7/30 (= 1/3 to 1/10) at RT0 and 17/60 (= 1 / 3-1 at RT2. / 20).

[Main effects in the second embodiment]
As described above, comparing the time controlled by RT0 and the time controlled by RT2, the one when the probability of winning one of the lip GRs 11 to 13 is low is controlled by RT2. The probability of winning a fall replay is low. Therefore, the probability of shifting to RT1 is lower when controlled by RT2 than when controlled by RT0. In addition, since the stock period ends when the transition is made to RT1, the probability that the stock period becomes longer is higher when controlled to RT2 than when controlled to RT0. Since RT0 and RT2 have the same replay probability, there is no difference in the ease with which the CZ game is given, but the probability that the stock period is longer is higher when controlled by RT2. For this reason, when the control is performed by RT2, more CZ games can be accumulated, so RT2 is more advantageous to the player than RT0.

[Third Embodiment]
In the third embodiment, a case will be described in which RT3 in the first embodiment described above is set to “first state”, RT4 is set to “second state”, and “right for lottery” is not a CZ game but a predetermined point. To do. Also, the same configuration / process as in the first embodiment is omitted, and a different configuration / process will be described. In the first embodiment and the second embodiment, the AT lottery is performed when a predetermined lottery object combination is won or when no lottery object combination is won. In the third embodiment, the main control unit 41 gives points when a specific lottery target combination is won, and performs AT lottery according to the points. Points are accumulated while being controlled to a predetermined gaming state. Further, when a transition is made from a predetermined gaming state to a different gaming state, an AT lottery is performed according to the total number of points accumulated while being controlled to the predetermined gaming state (see FIG. 24).

[About stock period]
A stock period in which points are given and accumulated will be described with reference to FIG. The stock period in which points are awarded and accumulated when controlled by RT3 or RT4, which shifts after being controlled by BB1 or BB2, which is higher than when the winning role is between RT0 and RT5, is set Is done. Points are awarded and accumulated during a period controlled by RT3 or a period controlled by RT4, and an AT lottery is performed according to the total number of points accumulated when moving to RT1.

  Each state of the third embodiment will be described with reference to FIG. As shown in FIG. 23 (A), when the control is performed by RT3 and when the control is performed by RT4, the lottery probability of the push order bell and the lottery probability of the replay are equal. In RT3, when one of the lip GRs 11 to 13 is won with a probability of 1/15, when a fall replay is won by the order of operating the stop switch 8, or in the order of pushing with a probability of 1/5 In the case of winning the bell, the gaming state shifts to RT1 when no winning combination is won and a transition outcome is derived. On the other hand, in RT4, when one of the lip GRs 11 to 13 is won with a probability of 1/20, when a fall replay is won in the order of operating the stop switch 8, or 1/5 In the case of winning the push order bell with the probability of, the gaming state shifts to RT1 when a winning game is derived without winning any of the small roles. In other words, when compared to when controlled by RT3 and when controlled by RT4, the fall replay is more controlled when RT4 is controlled with a lower probability of winning one of Lip GR11-13. The probability of winning a prize is low. Therefore, the probability of shifting to RT1 is lower when controlled by RT4 than when controlled by RT3. In RT3 and RT4, although the replay probabilities are the same, the probabilities of winning lip GR11-13 in the replay are different. Therefore, of the replays, the probability of winning a replay other than the replays GR11 to 13 is 8/105 (= 1 / 7-1 / 15) in RT3 and 13/140 (= 1 / 7-1 in RT4). / 20).

  As shown in FIG. 23B, in RT3 and RT4, points are awarded when a winning combination of bell, cherry or watermelon is won. Here, winning the bell means that the winning combination of any of the bells, left bells 1 to 4, middle bells 1 to 4, and right bells 1 to 4 shown in FIG. Winning a cherry means winning a lottery target in any one of the middle tier cherry, weak cherry, and strong cherry shown in FIG. Winning a watermelon means that one of the strong watermelons and the weak watermelons shown in FIG. 10 has been won. As shown in FIG. 23B, more points are awarded when controlled by RT4 than when controlled by RT3.

  When the main control unit 41 wins a lottery target to which points are given while controlling to RT3 or RT4, the main control unit 41 stores the points in a predetermined area of the RAM. The main control unit adds and stores each time a point is awarded until the gaming state shifts to RT1, and resets the point when an AT lottery is performed.

[About AT lottery]
In the third embodiment, AT lottery is performed according to the total of accumulated points during a period controlled by RT3 or a period controlled by RT4. The AT lottery will be described using the AT lottery table shown in FIG. The point in the figure is the total value of points accumulated during the stock period. The number of AT games given for each total value of accumulated points is determined. For example, if the total number of points awarded during the stock period is 4 to 6 points, it will be non-winning with a probability of 60%, and 30 AT games will be awarded with a probability of 10%, 25% 50 games of AT games are given with a probability of 100, and 100 games of AT games are given with a probability of 5%. As shown in FIG. 24, the larger the total number of points accumulated during the stock period, the easier it is to win the AT lottery and the higher the expected value of the number of AT games to be given.

  The main control unit 41 may perform AT lottery after starting control of RT1, or may perform AT lottery in the last game controlled to RT3 or RT4. For example, the AT lottery may be performed when the transition to RT1 is determined after the winning determination process is performed, or the AT lottery may be performed in the first game when the transition is made to RT1.

[Main effects in the third embodiment]
As described above, in RT3 and RT4 after BB1 or BB2 ends, points used in the AT lottery are given, so that the game after BB1 or BB2 ends can be expected, The interest of the game after being controlled by BB1 or BB2 is improved.

[Fourth Embodiment]
In the fourth embodiment, the BB1 in the first embodiment described above is set to the “first state”, the BB2 is set to the “second state”, and the “rights for lottery” is granted when a specific lottery target is won. A description will be given of the case. Also, the same configuration / process as in the first embodiment is omitted, and a different configuration / process will be described. In the first embodiment and the second embodiment, the AT lottery is performed when a predetermined lottery object combination is won or when no lottery object combination is won. In the fourth embodiment, the main control unit 41 performs an AT lottery depending on how many times a specific lottery winning combination is won during the period controlled by BB1 or the period controlled by BB2.

[About stock period]
With reference to FIG. 25, a stock period for counting the number of times a specific winning combination is won will be described. The period controlled by BB1 or BB2, which is higher than when the winning probability of the small combination is between RT0 and RT5, is a stock period in which the number of times the middle stage cherry that is a specific lottery target is won is counted.

  Each state of the fourth embodiment will be described with reference to FIG. The main control unit 41 controls to BB1 until 3 games are digested after starting control to BB1, and controls to BB2 until 5 games are digested after starting control to BB2. In addition, while being controlled by BB1, the middle cherries are won with a probability of 1/3. While controlled by BB2, the middle cherries are won with a probability of 1/2. That is, the period controlled by BB2 is longer than the period controlled by BB1, and the middle cherries are easier to win when controlled by BB2 than when controlled by BB1.

  The main control unit 41 counts the number of times the middle cherries are won each time the middle cherries are won after starting the control to BB1 or BB2, and stores them in a predetermined area of the RAM. The main control unit 41 ends the control to BB1 or BB2, and resets the number of wins stored in the RAM when performing AT lottery.

[About AT lottery]
In the fourth embodiment, AT lottery is performed depending on how many times the middle cherries are won during the period controlled by BB1 or the period controlled by BB2. The AT lottery will be described using the AT lottery table shown in FIG. As shown in FIG. 27, the probability of winning the AT lottery is set higher as the number of times the middle cherry is won is increased. The period for which the AT is controlled may be determined according to the number of times the middle cherries have been won, or may be determined to be controlled by the AT for 50 games uniformly when the AT lottery is won. .

  The main control unit 41 may perform AT lottery after starting control to RT3 or RT4, or may perform AT lottery in the last game controlled to BB1 or BB2. For example, the AT lottery may be performed when the transition to RT3 is determined after the winning determination process is performed, or the AT lottery may be performed in the first game when the transition is made to RT3.

[Main effects in the fourth embodiment]
As described above, when BB2 is controlled, the stock period is longer than when BB1 is controlled, and the probability of winning the middle stage cherries is higher, so it is more advantageous for the player than BB1. is there. In addition, when the period controlled by BB2 varies, it may be shorter than the period controlled by BB1 even though the player is in an advantageous state over BB1. In some cases the player may be frustrated. In the fourth embodiment, the period controlled by the stock period BB1 or BB2 is a period that does not vary as in the case of 3 games or 5 games, so the stock period is BB1 despite being in BB2. It will not be shorter than the inside. Therefore, the player's dissatisfaction when the stock period becomes shorter than BB1 despite the advantageous state of BB2 does not occur.

[Fifth Embodiment]
In the first to fourth embodiments, whether or not to control the AT is determined according to the number of games or points given during the stock period. In the fifth embodiment, the period to be controlled by the AT is determined based on the points given during the stock period.

[About AT]
The AT in the fifth embodiment will be described with reference to FIG. As shown in FIG. 28, in the case of winning a lottery target in any of the bell, weak watermelon, strong watermelon, weak cherry, strong cherry, middle cherry, BB1, and BB2 shown in FIG. 12 during non-AT. The AT lottery is performed. In the AT lottery, whether or not to control to the AT and if it is determined to control to the AT, the stock period from winning the AT to being controlled by the AT is determined. During the stock period, points are awarded when a specific lottery winning combination is won. In the stock period, when the remaining stock period becomes 0 game, a continuous lottery is performed to determine whether or not to continue the stock period in the next game. When the continuous lottery is not won, the control period for the AT is determined according to the total value of the points given during the stock period, and the control to the AT is started.

  The period during which the AT is controlled is determined using the AT game number determination table shown in FIG. The number of AT games is set so that the expected value of the number of AT games to be given increases as the total value of points given during the stock period increases.

[About stock period]
The stock period will be described with reference to FIG. The main control unit 41 determines an initial value of the stock period, points to be given, and whether to continue the stock period, depending on which gaming state is controlled. As shown in FIG. 30 (A), when the AT lottery is won and the game state is controlled to any one of RT1, 3-5, one game is played with a 50% probability as a stock period. Two games are set with a probability of 30%, and three games are set with a probability of 20%. On the other hand, when it is controlled to RT0 or RT2 when winning the AT lottery, the stock period is longer than when it is controlled to one of the gaming states of RT1, 3-5 Is likely to be set.

  During the stock period, points will be awarded when winning a lottery target of bell, cherry or watermelon. In RT0 to RT5, the probability of winning a bell, cherry or watermelon is equal. Also, as shown in FIG. 30 (B), more points are awarded when controlled to RT0 or RT2 than when controlled to one of the gaming states RT1, 3-5. Is done. In this case, when the gaming state shifts during the stock period, the points to be awarded are determined according to which gaming state is the gaming state when the winning combination is won.

  When the last game is consumed as a stock period, a stock period continuation lottery for determining whether or not to continue the stock period is performed using the stock period continuation lottery table shown in FIG. Stock period continuation lottery is performed with different winning probabilities depending on whether the period from winning the AT lottery until the remaining stock period is one game is less than 6 games or 6 games or more. In addition, the stock period continuous lottery is performed with different winning probabilities according to the gaming state when the last one game is consumed. For example, when the AT lottery is won and three games are set as the stock period, the stock period continuous lottery is performed in the last third game. At this time, when the game state in the third game is RT0 or RT2, the continuation of the stock period is determined with a probability of 90%. Thereafter, whether or not to continue the stock period for each game is determined with the same probability, and after six games have passed since the winning of the AT lottery, the continuation of the stock period is determined with a probability of 80%. As shown in FIG. 30 (C), the stock when the game state when winning the AT lottery is RT0 or RT2 is more stock than when the game state is one of RT1, 3-5. The probability of deciding to continue the period is high. When the gaming state shifts during the stock period, the stock period continuing lottery is performed based on the gaming state when the stock period continuing lottery is performed.

[Main effects in the fifth embodiment]
As described above, when the gaming state is RT0 or RT2, there is a higher probability that it is determined that the stock period will be continued than when the gaming state is one of RT1, 3-5, so RT0 or RT2 There is a higher probability that the stock period will be longer when controlled. In addition, since the period controlled by the stock period is determined by continuous lottery for each game, the stock period may be longer than expected. Therefore, the interest of the game during the stock period is improved.

[Main variations]
The present invention is not limited to the above-described embodiment, and various modifications and applications are possible. Hereinafter, modifications of the above-described embodiment applicable to the present invention will be described.

[Modification of First Embodiment]
In the first embodiment, the stock period is determined when the CZ lottery is won in the first embodiment and is not changed thereafter. However, as in the fifth embodiment, it is determined whether or not to continue the stock period. Stock period continuation lottery may be performed. At this time, the stock period continuous lottery is performed so that the continuation rate is higher in the second state than in the first state. In addition, if the gaming state has transitioned during the stock period, a lottery for stock period may be performed according to the gaming state after the transition, and a lottery for stock period may be performed according to the gaming state when the CZ lottery is won. May be performed. In the case where the stock period continuous lottery is performed according to the gaming state when the CZ lottery is won, the stock period continuous lottery can be performed without considering the gaming state during the stock period, so the processing is complicated. Can be prevented.

  In the first embodiment, the same lottery table is used for the CZ lottery and the CZ first lottery, but different tables may be used. In addition, in both cases where the CZ lottery is won and in the case where the CZ extra lottery is won, the number of CZ games is incremented by one. Also good. In this case, the CZ lottery and the CZ addition lottery are performed so that the expected value of the number of CZ games to be given is higher when the second state is controlled.

  In the first embodiment, the second state is set to a state in which the replay probability is lower than that of the first state, but the CZ is more controlled when the first state is controlled than when the second state is controlled. As long as the game is easy to be given, for example, the CZ game is given with different probabilities even when the replay probability is the same between when the game is controlled to the first state and when the game is controlled to the second state. It may be. In addition, during the stock period, the number of CZ games may be determined according to the number of times a specific lottery role (for example, a small role) is won.

  In the first embodiment, while the number of CZ games is not changed while being controlled by CZ, the CZ addition lottery may be performed while being controlled by CZ. When the CZ addition lottery is performed using the CZ lottery table as shown in FIG. 17A, when the second state having a higher replay probability is controlled to the first state. In comparison, it is easy to add a CZ game. Therefore, the period controlled by CZ tends to be longer when the second state is controlled than when the first state is controlled. Also, in the case of controlling to perform an AT lottery even when a replay is won while being controlled by the CZ, the AT lottery is won when controlled to the second state with a high replay probability. It becomes easy to do. Further, when the AT lottery is won and the CZ is controlled, the AT extra lottery may be performed. When the AT extra lottery is performed when the replay is won, since the opportunity to perform the AT extra lottery increases when the second state is controlled, the AT extra lottery is controlled. There is a higher probability that the time period when the AT is controlled becomes longer.

  As for the effect during CZ, the freeze effect is given as an example, but any effect that suggests that the probability of winning the AT lottery is high. For example, one reel is displayed in the transmission area 51b. If the number of symbols is three, it may be four or more. By increasing the number of symbols displayed in the transparent area 51b to four or more, the symbols that are hidden and not visible when three are visible can be visually recognized, and the chance to display symbols that suggest AT lottery such as cherry symbols is increased. Can do. Thereby, the player can expect that the probability of winning the AT lottery is high. Moreover, you may perform the effect which displays the symbol which suggests AT lottery on the liquid crystal display 51. FIG.

[Modification of Second Embodiment]
In the second embodiment, the CZ lottery is won in RT1 and the stock period is determined by lottery. However, when the CZ lottery is won, the same period may be set uniformly. In addition, when the CZ lottery is won in RT1 and the stock period is set, and the process shifts to RT0 during the stock period, the stock period is not changed, but the stock period may be changed. For example, the stock period may be controlled again to RT1. In this case, as an effect of displaying how many games remain in the stock period, for example, the display of the stock period displayed in RT1 may be switched to the display of “???”.

[Modification of Third Embodiment]
In the third embodiment, the AT control period is determined at the time of AT lottery. However, as in the fifth embodiment, after the AT lottery is won and the AT control is determined, the stock period is set. The period for which the AT is controlled may be determined based on the points provided during the stock period. The stock period after winning the AT lottery may be determined according to the gaming state when the points related to the AT lottery are awarded, or may be determined according to the gaming state at the time of the AT lottery.

[Modification of Fourth Embodiment]
In the fourth embodiment, BB1 is in the first state and BB2 is in the second state, but the present invention is not limited to the bonus. For example, it is possible to set the first state when it is a precursor period until the transition to AT and is controlled by RT1, and set the second state when it is controlled by RT2 or RT0. The number of times of winning the replay as a special winning combination during the precursor period may be counted, and the number of AT games may be determined based on the total number of winners of the normal replay during the precursor period. At this time, the winning probability of normal replay is set so that RT1 <RT2 = RT0. Further, the precursor period set in RT1 and the precursor period set in RT2 or RT0 are set so that the precursor period set in RT1 is shorter. For example, 10 games may always be set as the precursor period in RT1, and 32 games may always be set as the precursor period in RT2 or RT3.

[Modification of Fifth Embodiment]
In the fifth embodiment, the continuation rate of the stock period is determined based on the gaming state when the lottery for stock period continuation is performed, but may be determined based on the gaming state when the AT lottery is won. By determining in this way, it is not necessary to consider the gaming state when performing the stock period continuous lottery, and the processing burden on the main control unit 41 can be reduced.

[How to adjust the length of the stock period]
As an example of a method of adjusting the length of the stock period, as shown in the second to third embodiments, the stock period is set as a stock period while being controlled to a specific gaming state, and the other is changed from the specific gaming state. The method of changing the probability of transitioning to the gaming state by changing the probability of winning the fall replay and adjusting the period controlled by the specific gaming state as the stock period was cited. In such a case, it is only necessary to increase the opportunity to shift from the first state to another gaming state rather than the opportunity to shift from the second state to another gaming state. The game state is changed from the first state to another game state when the transition to the game state is derived from the winning of the fall replay or the derivation of the transition result, and the opportunity to move from the second state to another game state is derived from the transition state. You may make it increase the opportunity to transfer to. In the second embodiment, the number of opportunities for shifting from the second state to another gaming state may be greater than the opportunity for shifting from the third state to another gaming state. The transition from one state to another gaming state is the derivation of the fall replay winning or transitioning outcome, and the transition from the third state to another gaming state is the derivation of the transitioning outcome, so that the second state is another You may make it increase the opportunity which transfers to this game state.

  Further, the stock period end condition is not limited to the number of games as shown in the fourth embodiment. For example, it may be terminated when the number of medals paid out exceeds a predetermined number after the stock period starts. Specifically, the medal payout rate per game is the same in the first state and the second state. In the first state, the stock period ends when 50 medals are paid out, and in the second state The stock period may end when 400 medals are paid out.

  In addition, as a method for setting the stock period in the first embodiment, there is a determination method by lottery. For example, the expected value of the stock period determined when controlled to the second state may be higher than the expected value of the stock period determined when controlled to the first state. More specifically, in the first state, a stock period of 1-3 games is set when two or more replays are won, and in the second state, 14-16 games are won when two or more replays are won. A stock period may be set. Also, in any of the first state and the second state, the stock period is set to any one of 1 to 16 games, but in the first state, it is easily set to 1 to 3 games. In the state, it may be easy to set 14 to 16 games. Further, a stock period of 14 to 16 games may be set when the first state is shifted to the second state.

  Further, in the first embodiment, a stock period may be set when shifting from the first state to the second state. For example, when the CZ lottery winning combination is continued twice during the first state, the stock period is set to 1-3 games, and when shifting to the second state, the stock period is set to 14-16 games. The probability may be increased. In such a case, if the stock period is set during the first state and the second period is entered during the stock period, the stock period may be reset, or the stock period may be added, The stock period may not be added. Further, when resetting the stock period, it may be reset only when the stock period to be reset is longer than the already set stock period.

  In the first embodiment as well, the period controlled to the gaming state is set as the stock period, and the trigger for shifting to another gaming state is changed between the first state and the second state, thereby reducing the length of the stock period. You may adjust.

[About period suggestion]
In the first embodiment, the period suggesting effect is an effect of displaying how many games remain in the stock period, but any effect suggesting that the stock period is in progress may be used. The effect “” is a period suggesting effect, and when being controlled in the second state, “in a chance” may be emphasized and displayed as compared to when controlled in the first state. Displaying with emphasis includes increasing the brightness of the colors used for production, increasing the saturation, and displaying in different hues. It also includes using multiple colors for production. For example, the period suggesting effect may be performed using black or rainbow color in the second state while the period suggesting effect is performed using black in the first state. Further, the colors used for the production include the color of the character, the color surrounding the character, the color of the lamp, the color of the background, and the like. Further, although the period suggesting effect is an effect of displaying a predetermined image on the liquid crystal display 51, an effect by sound may be used. In the production of sound, the production suggesting that it is during the stock period is production of outputting a sound such as “during chance” or “5 remaining games”. The effect emphasized in the sound effect includes an effect using a high sound, a large volume, and a sound with a high playback speed. Moreover, it is good also as an effect which emphasized the effect using the voice of the character with a low appearance rate when a plurality of characters appear in the game of the slot machine.

  Further, in the first embodiment, as shown in FIG. 18A, a character image “chance is in progress” is always displayed during the stock period, or an image such as the number of remaining games in the stock period is displayed. However, during the stock period, characters such as “Please press the button” are displayed on the liquid crystal display 51 to prompt the operation of the effect switch 56 and detect the operation of the effect switch 56. An effect that suggests that it is during the stock period may be performed.

[Right suggestion]
In the first embodiment, as the right suggesting effect, an effect of displaying the number of CZ games accumulated during the stock period as the number of stars is performed, but the present invention is not limited thereto. For example, the amount stocked by the lamp may be suggested. Specifically, lamps or LEDs attached to the front door 1b or the like may be turned on in the order of rainbow>red>green>yellow>blue> white in order of increasing stock amount. Moreover, you may suggest the amount stocked by the cry of the animal from which the physique, the magnitude of a cry, and the image which a player recalls differ. For example, the cry may be output in the order of lion>dog> cat in descending order of the stocked amount. That is, it may be set so as to indicate that there is a large amount of stocks of animals that have a large physique like a lion, a loud cry, or a strong image. Moreover, it may be set to indicate that the amount of stocks of animals that have a small physique like a cat, a small cry, or a weak image of the animal is stocked.

[Display of stock period]
In the first embodiment, the example in which the display of the stock period does not change has been described. However, the display of the stock period may be updated. For example, when the extension of the stock period is determined during the stock period, the display of the stock period may be switched.

[About specific operations]
In 1st Embodiment, although operation to the switch 56 for an effect was mentioned as an example as specific operation, it is not restricted to this. For example, it may be an operation to other operation means, and the slot machine 1 is provided with an information detection unit capable of reading information from the outside, and a specific operation for causing the information detection unit to read predetermined information It is good.

[When stock period ends]
In this embodiment, the transition to the CZ state or the AT lottery is performed when the stock period ends, but the transition to the CZ state or the AT lottery is started after a predetermined period has elapsed since the end of the stock period. May be.

[About the lottery regarding the transition of advantageous status]
In the present embodiment, as an example of the lottery regarding the transition of the advantageous state, the AT lottery performed during the non-AT is described as an example, but the AT lottery performed during the AT may be used. Specifically, the state controlled by the AT at RT1 is the first state, the state controlled by the AT at RT0 or RT2 is the second state, and when the AT is controlled, the AT extra lottery condition The stock period is set when the stock is established, and whether or not to add the AT game number and the number of AT games to be added are determined by AT extra lottery based on the rights granted and stored during the stock period. May be. Also, when it is decided to add the number of AT games, a stock period may be set, and the number of AT games to be added may be determined based on the stored right.

[Rights related to lottery]
In the present embodiment, as the right related to the lottery, the right related to the AT lottery is given as an example, but the right is not limited thereto. The right relating to the lottery includes a right that affects the probability of shifting to the advantageous state, a right that affects the period during which the advantageous state is controlled, and a right that affects the degree of advantage during the advantageous state. Specifically, it may be determined which of the plurality of advantageous states with different replay probabilities to shift to based on the right relating to the lottery.

[Advantageous state]
In the example described above, the AT is exemplified for the slot machine as an advantageous state. However, the slot machine is not limited to this as long as it is advantageous for the player, and an example of the slot machine will be described below.

  Advantageous states include, for example, a regular bonus (RB) and replay time (RT) in which a winning probability of a predetermined winning combination is high, a concentrated state of small roles, and a range in which at least one reel can be pulled in than normal. The operation procedure for winning the winning small role is not predetermined, but the challenge time (CT) and the winning probability of winning the winning role are not changed. It may be a pseudo bonus that is notified over a period (for example, until 50 games are consumed). In addition, the probability of being controlled to these advantageous states may be a high probability, the probability of being controlled to the freeze state is high, and the number of games such as the number of AT games is high. You may set the advantageous state of a different aspect from the said embodiment, such as the state added and the state where it is easy to increase the number of additional games of AT. In addition, it is indirectly advantageous for the player, such as the condition for obtaining a privilege on the communication line network and the probability that the condition for executing a premium effect (freeze effect, premium effect, etc.) is established. It may be a state where a special privilege or an interest of the game is improved. Further, the allowance determining means for determining whether or not to allow the transition to an advantageous state is not limited to the internal lottery process, and may be a means for determining regardless of the winning combination.

  Further, the advantageous state is given when, for example, in the privilege grant lottery that determines whether or not a privilege is granted, the “probability that a privilege is granted” and “the privilege is given” are determined. At least one of “the value of the privilege (or the expected value of the privilege)” may be higher than the normal state (a state different from the advantageous state). In addition, the advantageous state may be one in which the number of execution opportunities for the privilege grant lottery is larger than that in the normal state. In addition, the advantageous state may be a state where the number of digestion-required games that need to be digested in order to give a privilege is less than a normal state.

  For example, in the case where the privilege is the number of AT games, the advantageous state means that “AT winning probability in AT lottery” and “AT awarded when winning AT in AT lottery” than in the normal state At least one of “the value of the number of games” may be higher than the normal state. Further, the advantageous state may be that the number of AT lottery triggers is larger than that in the normal state. For example, when the AT lottery execution opportunity in the normal state is the first role winning and the second role winning, the AT lottery execution opportunity in the advantageous state is the first role winning and the second role winning. In addition to the above, it is possible to win the third role.

[Modification of slot machine]
In the above embodiment, the slot machine that pays out game media to the player's hand according to the occurrence of a win has been described. However, the game medium is enclosed, and the game media is paid out to the player's hand when a win occurs. An enclosing slot machine that adds game points (scores) without any change may be adopted. The base and the drum can be distributed, and the chassis is common and only the base or the base and the drum is called a gaming machine. In addition, the slot machine has a game area in which a game ball can be launched and a game can be played, and a betting amount can be set according to the game ball passing through a predetermined area provided in the game area. May be.

[About benefits]
In the above-described example, the value directly affecting the payout rate of medals and pachinko balls, such as BB winning, AT winning, and the number of AT games that can be controlled by the AT, is exemplified as the privilege. However, the privilege may be a value that improves the degree of advantage for the player, and may be a value that does not directly affect the medal payout rate, for example. Specifically, when an AT lottery has a high probability state in which AT is won with a higher probability than usual, execution of a probability suggestion effect to suggest whether or not the current state is a high probability state , Execution of a premier effect together with sound on the liquid crystal display 51 (special character appearance, execution of special bonus effect in the next generated bonus, etc.), execution of a set value suggestion effect to suggest a set value, Collecting a certain number of liquid crystal displays a two-dimensional code that gives points that can be exchanged for services determined at the amusement store where the slot machine 1 is installed, and that can download bonus videos and bonus information on a predetermined website A display or the like may be displayed in the device 51.

  Moreover, although the number of AT games is illustrated as an example of the privilege, the privilege related to the AT is not limited to this. Good. In addition, when the number of times that the navigation effect can be executed is determined and the AT is controlled until the navigation effect is executed for the determined number of times that the navigation effect can be executed, Good. Further, for example, when the upper limit grant amount is determined and the AT is controlled until the assigned game value (medal payout number) reaches the determined upper limit grant amount, the upper limit grant amount may be a privilege. In addition, when the AT is controlled from when the predetermined AT start condition is satisfied until the predetermined AT end condition is satisfied, and if the AT is continued when the AT end condition is satisfied, the continuous lottery is performed. The continuation probability determined to continue in the lottery may be used as a privilege.

[About production and notification]
In the above-described example, an example in which the liquid crystal display 51 is used to produce effects and notifications is given. For example, speakers 53 and 54, a back lamp (reel LED 55 in the above embodiment) arranged on the back side (inside) of the reel. ), Transmissive liquid crystal display arranged on the front side of the reel (liquid crystal display configured so that the reel can be seen), lamps and LEDs mounted on the front door 1b, etc., vibration of the stop switch, around the stop switch The effect may be executed by means different from the above-described embodiment, such as air blowing from the air or a change in the temperature of the stop switch.

[About AT]
In the example of the slot machine, the example in which the main control unit 41 executes the control related to the AT has been described. However, the AT related control executed by the main control unit 41 includes execution of an AT lottery. AT lottery may include winning or non-winning AT lottery, determining whether or not to stock the number of AT games, determining the number of AT games, increasing the number of AT games, etc. . In addition, as a control related to the AT, a high probability state control of the AT lottery is exemplified. For the control of the high probability state of the AT lottery, the control for increasing the probability of winning the AT lottery, the control for shortening the period until the AT is controlled according to the result of the internal lottery, Includes controls that favor the number of games. Further, as control related to AT, it is possible to control to AT when a prescribed number of games have been consumed. The case where the prescribed number of games have been consumed includes the case where the ceiling game number is reached and the case where the number of games determined by lottery is reached. Further, as control related to AT, control for setting a precursor period can be cited. The control for setting the precursor period includes, for example, control for producing effects of 0 to 32 games in the precursor period before the start of AT. Moreover, control which gives a penalty is mentioned as control which concerns on AT. The control for giving a penalty includes determination of penalty contents and determination or setting of a penalty period. In addition, as control related to AT, the main control unit 41 performs lighting control of a lamp and an LED indicating that AT is in progress.

  In addition, as the control related to AT, the main control unit 41 performs lighting control of lamps and LEDs for executing a navigation effect. Further, the sub control unit 91 may execute the navigation effect in conjunction with the main control unit 41 executing the navigation effect. Further, when the main control unit 41 improves the lottery probability, for example, when controlling to the high probability state of the AT lottery, for example, this is notified by lighting control of a lamp or LED (for example, the game auxiliary display 12). You may do it. More specifically, the main control unit 41 may notify that it is controlled to the high probability state of the AT lottery by executing the navigation effect a predetermined number of times by the game auxiliary display 12. Alternatively, the main control unit 41 may notify the sub-control unit 91 that the navigation effect is executed a predetermined number of times to control to the high probability state of the AT lottery.

  When the main control unit 41 executes the control related to the AT, it is preferable that the process of the main control unit 41 is executed by the control unit subordinate to the main control unit 41 and subordinate to the main control unit 41. . For example, the control unit provided on the board other than the game control board executes the reel stop control, and the main control unit 41 transfers the operation signal of the stop switch to the control unit. In this way, by causing the lower-level control unit to perform the control of the main control unit 41, it is possible to prevent the capacity of the ROM 41b and the RAM 41c from being insufficient and the processing capacity of the main CPU 41a from being insufficient when performing the control related to the AT.

  In the above-described embodiment, the main control unit 41 executes the control related to the AT. However, the sub-control unit 91 may execute the control. For example, the sub-control unit 91 performs an AT lottery process or an extra lottery process based on an internal winning command from the main control unit 41, and executes a process for controlling the AT or a navigation effect according to the result. These processes may be performed.

[Setting change status and setting check status]
With regard to the setting change state, it is also possible to shift to the setting change state on condition that “power ON” + “setting key switch ON” + “front door opening detection”. Thereby, an unauthorized setting change in a state where the front door is not opened can be prevented. Once the setting change state is entered, the setting change state is maintained regardless of the open / closed state of the front door until the end condition (setting key switch is turned OFF after setting value is established) is satisfied. You may make it do. As a result, even if the front door is closed during the setting change state, the setting change state is not terminated, so that it is possible to prevent the trouble of shifting to the setting change state again.

  In addition, regarding the setting confirmation state, “setting key switch ON” + “front door opening detection” may be used as a condition to shift to the setting confirmation state. Thereby, unauthorized setting confirmation in the state where the front door is not opened can be prevented. Once the setting confirmation state has been entered, the setting confirmation state is maintained regardless of whether the front door is open or closed until an end condition (setting key switch is turned OFF) for ending the setting confirmation state is satisfied. Also good. Thereby, even if the front door is closed during the setting confirmation state, the setting confirmation state is not terminated, and therefore it is possible to prevent the trouble of shifting to the setting confirmation state again.

[About reel]
In the above-described embodiment, a plurality of reels capable of variably displaying each of a plurality of types of identifiable symbols are provided, and after the reels are variably displayed, the display result is derived by stopping the variability display of the reels. A slot machine that can generate a winning according to the combination of reel display results has been described. In other words, a plurality of variable display units capable of variably displaying a plurality of types of identification information each identifiable are provided, and after the variable display unit is variably displayed, the display result is derived by stopping the variable display of the variable display unit. The slot machine is described in which a winning can be generated according to a combination of display results of a plurality of variable display units.
