Description

  The present invention relates to a slot machine.

  Conventionally, the internal lottery to determine the winning combination by operating the start lever with the medal bet is started, the rotation of the plurality of reels is started, the plurality of reels are stopped by operating the stop button, There is known a slot machine in which a medal is paid out as a payout for a winning combination when a winning combination is won in an internal lottery.

  In many of the conventional slot machines, when a plurality of types of small combinations or re-playing combinations with different winning combinations are won as a result of internal lottery, the plurality of types of small combinations or An assist time (hereinafter referred to as AT) function for notifying information necessary for winning a winning combination among the re-game players (hereinafter referred to as winning navigation information) is installed.

The AT lottery for determining whether or not to shift from the normal state where the AT function does not operate / the operation frequency is relatively low to the AT state where the AT function operates / the operation frequency is relatively high is the normal state As a result of the internal lottery, the winning combination is executed when the winning combination has a relatively low winning probability (including the case where the winning combination is relatively low, including the case where the winning combination is rare). It is common.
In addition, there is a known slot machine that shifts to an AT state through a precursor state over a predetermined number of games without immediately shifting to an AT state when winning an AT lottery (see, for example, Patent Document 1). .

  In the slot machine that transitions to the AT state through the precursor state, the precursor state is triggered by the execution of the AT lottery, that is, the rare role winning, regardless of the result of the AT lottery. Further, during the precursor state, a unique precursor effect is executed on the effect display device, and it is suggested whether or not the AT lottery is won by the precursor effect.

  By mounting the precursor state, the player cannot leave the slot machine until the end of the precursor state where the result of the AT lottery becomes clear. As a result, there is an effect of contributing to an improvement in the operation of the slot machine.

JP 2014-147536 A

  As described above, the slot machine that transitions to the AT state through the precursor state has the advantage that the operation can be improved. Therefore, although it is a convenient specification for game machine manufacturers and halls, it is relatively after the end of the precursor state. Since there are many cases in which the state does not shift to the AT state, if the precursor state is merely used as a postponement period for notifying the AT lottery result, the player may be disgusted and may deteriorate the operation.

  Therefore, an object of the present invention is to provide a slot machine that can realize a precursor state that can enhance a player's interests by eliminating the negative image as described above.

In the slot machine of the present invention, the result of the lottery means (internal lottery process of the main control unit 100A) for performing the lottery of the part and the lottery (internal lottery process of the main control unit 100A) by the part lottery means is a specific result. In some cases (for example, at the time of winning the push order small role in FIG. 3), notification means for notifying auxiliary information for assisting the winning of a predetermined role (the correct push order in which the 7 small payouts wins) and normal game A transfer right granting lottery (AT lottery process A) for lottering whether or not to grant the right to shift to a special gaming state (AT state) in which the notification frequency by the notification means is higher than the normal gaming state during the state; It is equipped with.
The normal gaming state includes a low-probability normal gaming state (normal part P1) and a high-probability normal gaming state in which the transfer right granting lottery means has a higher probability than the low-probability normal gaming state. (CZ part P3).

  In addition, the slot machine of the present invention, regardless of the result of the lottery, when the lottery (AT lottery process A) is executed by the transfer right grant lottery means in the low-probability normal gaming state (normal part P1) When the end condition is satisfied during the precursor state starting means (step S1009 in FIG. 10) for starting the precursor state (precursor part P2) and the precursor state (precursor part P2) started by the precursor state starting means, When the precursor state is terminated by the precursor state ending means (step S1202 and step S1209 in FIG. 12) for ending the precursor state and the precursor state ending means, the transfer right is granted. Special game state start means (step S1210 in FIG. 12) for starting the special game state, conditions during the precursor state, and completion of the precursor state High-precision normal game state transition lottery means (CZ lottery processing) for drawing whether or not to shift to the high-probability normal game state on the condition that the transition right is not granted when the sign state is ended by means B and CZ lottery processing C), numerical value initialization processing at the start of the precursor state (processing of setting an initial value of zero to the number of points in step S1101 in FIG. 11), and the precursor state (precursor part P2) A numerical value update process including a numerical value addition process (a process of adding 1 to the number of points in step S1110 in FIG. 11) when a predetermined game condition is satisfied, regardless of whether the transfer right is given or not. Numerical value updating means for executing, and numerical information notification means for notifying information related to the numerical value updated by the numerical value updating means (point display area 30b in FIG. 14 (a)). Normal gaming state transition selecting means is a probability corresponding to the values updated by the numerical updating means (number of points), and characterized in that lottery whether to shift to the high probability normal gaming state.

  According to the slot machine of the present invention, when the precursor state is started by the precursor state starting unit, the numerical value is initialized by the numerical value initialization process of the numerical value updating unit. Further, during the precursor state, when a predetermined game condition is satisfied, addition of numerical values is executed by numerical value initialization processing of the numerical value updating means. It should be noted that the numerical value initialization process and the numerical value update process by the numerical value update means are executed regardless of whether or not the transfer right has already been granted, and information related to the numerical values updated by the numerical value update means is numerical information notification. The player is notified by means.

Then, at the end of the precursor state and at the end of the precursor state, a lottery for determining whether or not to shift to the high-probability normal game state is executed by the high-probability normal game state transfer lottery means on condition that the right to transfer is not granted. . As a result, during the precursor state, the expectation for establishment of a predetermined game condition in which the numerical value updating process is executed by the numerical value updating means, and the high probability normal gaming state by the winning in the lottery by the high probability normal gaming state transition lottery means A new sense of expectation for the transition can be given.
In addition, at the end of the precursor state, not only the expectation for the transition to the special gaming state, but also a new expectation for the transition to the highly certain normal gaming state by the lottery by the lottery means for the high probability normal gaming state transition I can do it.
As a result, it is possible to realize a precursor state that can further enhance the interest of the player.

  In a specific configuration, the numerical value updating means performs an initial value set in the numerical value initialization process at the start of the precursor state and / or the numerical value addition process depending on whether or not the transfer right is granted. The addition value to be added to the original numerical value may be determined.

  According to the specific configuration, the initial value set in the numerical value initialization process at the start of the precursor state and / or the expected value of the added value added to the original numerical value in the numerical value addition process by the numerical value updating means Is set differently depending on whether or not the transfer right is granted, the player can infer whether or not the transfer right is granted depending on the initial value and / or the increase degree of the numerical value. It becomes possible.

  According to the slot machine of the present invention, dissatisfaction given to the player can be suppressed even if the period during which the player cannot leave the gaming table, which corresponds to the precursor period, is lengthened.

<4. Basic game processing>
The slot machine 1 sequentially executes a medal acceptance process, a bet process, a lever acceptance process, an internal lottery process, a reel rotation process, a reel stop process, a symbol determination process, and a privilege grant process in one game. The outline of each process will be described below.

(1) Medals Accepting Process When a medal is inserted into the medal insertion slot 10, the slot machine 1 accepts the inserted medal and takes it into the slot machine 1 or accepts the inserted medal in the medal tray 40. Return to Specifically, when the bet number is 3 and the credit number is less than 50, when a medal is inserted into the medal slot 10, the main control unit 100A takes the inserted medal into the slot machine 1, and Add credits. When the bet number is 3 and the credit number is 50, when a medal is inserted into the medal insertion slot 10, the main control unit 100A drives a solenoid provided in the medal detection device to insert the inserted medal. Return to medal tray 40.

(2) Bet processing The slot machine 1 sets the number of bets necessary for starting the game in accordance with the insertion of medals into the medal insertion slot 10, the operation of the bet button 11, or the winning of the re-gamer. Specifically, when a bet is less than 3, when a medal is inserted into the medal slot 10, the main control unit 100A adds the bet number by the number of inserted medals. When the bet button 11 is operated when the bet number is less than 3, the main control unit 100A subtracts the credit number and adds the bet number. Although details will be described later, when the re-gamer wins, the main control unit 100A executes an automatic bet process for betting again the bet number bet on the game without subtracting the credit number.

(3) Lever Acceptance Processing The slot machine 1 starts a game when the start lever 12 is operated with three medals bet. Specifically, when the start lever 12 is operated with the bet number set to 3, the main control unit 100A executes a game process after an internal lottery process to be described later. On the other hand, when the start lever 12 is operated in a state where the bet number is set to less than 3, the main control unit 100A does not execute a game process after the internal lottery process described later.

(4) Internal lottery process As the game starts, the slot machine 1 determines information for deriving a game result by lottery. Specifically, when the start lever 12 is operated with the bet number set to 3, the main control unit 100A executes an internal lottery process.
The internal lottery process is a process for determining, by lottery, a winning combination of one or a plurality of combinations or a loss that does not win any combination from a plurality of predetermined combinations.
In the internal lottery process, the main control unit 100A acquires one random value from a range of 0 to 65535 using a random number generator (not shown). Then, according to the acquired random number value, it is determined whether or not one or a plurality of winning combinations are won or no winning combination is won.

FIG. 3 shows the target combination of the internal lottery process of the slot machine 1.
The target combination includes replay and seven types of small combinations. The winning probabilities and loss probabilities of each target role are highest in replay, and in the following order, small role, loser, small role 1, small role 2, rare small role 1, rare small role 2, rare small role 3, and rare small Set to role 4.
Among the seven types of small combinations, the push-order small combination is a case where a small combination with three payouts and a small combination with seven payouts are selected and the stop buttons 13a to 13c are operated in a predetermined order. In other words, when a small combination with seven payouts is won and operated in an order other than the predetermined order, the payout is a small combination set so that three small combinations win. Hereinafter, the operation order of the stop buttons 13a to 13c in which a small winning combination with seven payouts when winning a pressing order small combination is referred to as a correct answer pressing order.
In addition, since there are six operation orders of the stop buttons 13a to 13c, at least six kinds of push order small roles in which any one of these six operation orders is set in the correct push order are included. This is called a push order small combination.

(5) Reel Rotation Process After executing the internal lottery process, the slot machine 1 rotates each of the reels R1 to R3 in order to variably display the symbols arranged on the reel R. Specifically, the main control unit 100A rotates each of the reels R1 to R3 by continuously supplying pulses to each of the stepping motors that drive the reels R1 to R3.

(6) Reel stop processing The slot machine 1 stops the rotation of the reels R1 to R3 when the stop button 13 is operated during the rotation of the reels R1 to R3. Specifically, when the stop buttons 13a to 13c corresponding to the rotating reels R1 to R3 are operated, the main control unit 100A drives the reels R1 to R3 corresponding to the operated stop buttons 13a to 13c. By supplying a predetermined pulse to the stepping motor, the rotation operation of the corresponding reels R1 to R3 is stopped.

In the reel stop process, the winning combination is determined by the internal lottery process within the range of the reel rotation amount for a maximum of 4 symbols from the timing at which the operation of the stop buttons 13a to 13c to the rotating reels R1 to R3 is received. Is a process of stopping the rotating operation of the reels R1 to R3 so as to draw the symbols constituting the symbol on the winning line L1.
In the reel stop process, the winning symbol corresponding to the winning combination in the internal lottery process is drawn on the winning line L1 as much as possible and stopped so-called pull-in control and the winning combination in the internal lottery process. The so-called kicking control for controlling the drawing of the symbols is executed simultaneously so that the winning symbols corresponding to other combinations other than the corresponding winning symbols are not formed on the winning line L1.
Further, for example, a plurality of types of small combinations having different payouts, such as a push order small combination, may be selected and all of a plurality of symbols constituting a plurality of types of small combinations will be drawn on the winning line L1. If possible, either the symbol constituting the winning symbol of the small part with a large payout or the symbol with the largest number of winning symbols that has the possibility of winning is drawn on the winning line L1 and stopped.

(7) Symbol Determination Process The slot machine 1 determines the symbol combination that is stopped and displayed on the winning line L1 after all the reels R1 to R3 are stopped. When the symbol combination stopped and displayed on the winning line L1 is a winning symbol corresponding to the winning combination in the internal lottery process, the winning combination is determined and the process proceeds to the next privilege granting process. On the other hand, if the winning symbol corresponding to the winning combination in the internal lottery process is not established on the winning line L1, it is determined that the game is lost, the next bonus grant process is skipped, and the medal acceptance process state is entered. Transition.

(8) Bonus granting process The slot machine 1 executes a process of granting a bonus according to the winning combination determined to be a winning when it is determined to be a winning in the symbol determining process. Specifically, when it is determined that the winning combination of the small role, the number corresponding to the payout of the winning small role is added to the number of credits, or when the number of credits exceeds 50, the medal payout device is driven. Then, the medal tray 40 is paid out.
If it is determined that the re-gamer wins, automatic bet processing is executed. In the automatic bet process, the same number as the bet of the immediately preceding game is set as the bet number without inserting additional medals or reducing credits.
Then, the process shifts to the medal acceptance process state and the game process related to one game is finished.

<5. About the game state>
(1) Normal Game State The slot machine 1 includes a normal game state that is a normal game state and a special game state that is advantageous to the player as compared to the normal game state. More specifically, the special game state is an AT (Assist Time) state that informs the player of the correct answer push order when winning the push order small role by the internal lottery process. Compared to the normal gaming state in which no notification is made, the player can acquire many medals.
The slot machine 1 shifts the gaming state to the AT state when a predetermined start condition is satisfied in the normal gaming state, and shifts the gaming state to the normal gaming state when a predetermined end condition is satisfied in the AT state. In this way, the slot machine 1 advances the game while switching the game state between the normal game state and the AT state.

As shown in FIG. 4, the normal gaming state is composed of three parts: a normal part P1, a precursor part P2, and a chance zone (hereinafter referred to as CZ) part P3.
In the slot machine 1, the normal part P1 does not directly shift to the AT state, but shifts to the AT state via the precursor part P2 or the CZ part P3. Details of the normal part P1, the precursor part P2, and the chance zone (hereinafter referred to as CZ) part P3 will be described later.

(2) Special gaming state The slot machine 1 is in the AT state on condition that the AT transition right is granted at the end of the precursor part P1 and the AT transition right is granted by the lottery at the end of the CZ part P3. To start.
At the start of the AT state, the number of initial games for continuing the AT state is determined, and when the additional condition is satisfied during the AT state, the number of continued games is increased. The number of continuing games is decremented by one for each game in the AT state, and when the number of continuing games becomes zero, the AT state ends and falls to the normal gaming state, more specifically, to the normal part P1.

(3) Normal part P1
The normal part P1 is a part that is set as an initial state after the slot machine 1 is reset.
In the normal part P1, the slot machine 1 determines whether or not to grant the AT transfer right according to the type of the winning combination in the internal lottery process (hereinafter referred to as an internal winning combination) as shown in FIG. AT lottery process A, CZ lottery process A for determining whether or not to shift to CZ part P3, and mode up lottery process and mode fall lottery process for changing the internal game mode affecting the winning probability in AT lottery process A Execute.
When the AT lottery process A is executed, regardless of the result, the normal part P1 is finished in the game and the precursor part P2 is started from the next game.
When the CZ lottery process A is won, the normal part P1 is ended in the game, and the CZ part P3 is started from the next game.

The flow of processing in the normal part P1 in the slot machine 1 will be described with reference to FIG.
First, after executing an internal lottery process in step S1001, a mode-up lottery process is executed in the next step S1002, and a mode fall lottery process is executed in the next step S1003.

The mode-up lottery process in step S1002 affects the current internal mode among the three low-accuracy, normal, and high-probability internal modes (see FIG. 7A) that affect the winning probability in the AT lottery process A. This is a process for determining whether or not to promote the internal mode one level above.
The trigger for the mode-up lottery process is set when the internal winning combination is other than replay as shown in FIG. Further, the mode-up lottery process is executed when the internal mode is low and normal, and is not executed when the internal mode is high. More specifically, if the current internal mode is low-probability, whether to promote normally, or if the current internal mode is normal, lottery is selected. As shown in FIG. 5, the winning probability in the mode-up lottery process is determined according to the type of the internal winning combination, and the winning probabilities are in the descending order of winning in the push order small combination, lost, and small combination 1 It is set at the time of winning, at the time of winning small role 2, at the time of winning rare role 1, at the time of winning rare role 2, at the time of winning rare role 3, and at the time of winning rare role 4.

On the other hand, the mode drop lottery process in step S1003 is a process for determining whether or not to drop to the internal mode one level lower than the current internal mode. The trigger for the mode drop lottery process is set when the internal winning combination is replay as shown in FIG. The mode drop lottery process is executed when the internal mode is highly accurate and normal, and is not executed when the internal mode is low accurate. More specifically, a lottery is performed to determine whether or not a normal fall occurs when the current internal mode is high, and whether or not a low fall occurs when the current internal mode is normal.
The current internal mode is suggested to the player by the stage or background of the effect executed on the liquid crystal display device 30. The player can infer the current internal mode from the stage and background of the production, and recognize that the internal mode has been promoted or dropped due to the change of the stage or background of the production. I can do it.

  Returning to FIG. 10, in the next step S <b> 1004, it is determined whether or not the opportunity for the AT lottery process A is won. The trigger of AT lottery processing A is set when the internal winning combination is a rare small combination 1, a rare small combination 2, a rare small combination 3, or a rare small combination 4, as shown in FIG. Therefore, in step S1004, if the internal winning combination is a rare combination 1, a rare combination 2, a rare combination 3, or a rare combination 4, it is determined to be yes, and otherwise it is determined to be no.

Returning to FIG. 10, when it is determined YES in step S1004, AT lottery processing A is executed in the next step S1008. FIG. 7A shows the winning probability in the AT lottery process A according to the internal winning combination and the internal mode.
As shown in FIG. 7 (a), at the time of winning the rare small role 1, the winning probability is 3% when the internal mode is low, the winning probability is 6% in the normal case, and the winning probability is 12 when the high probability is high. % Is set.
At the time of winning the rare small role 2, the winning probability is set to 6% when the internal mode is low, the winning probability is set to 12% in the normal case, and the winning probability is set to 24% when the internal mode is high.
At the time of winning the rare small role 3, the winning probability when the internal mode is low is set to 15%, the winning probability when normal is set to 25%, and the winning probability when set to high is set to 100%.
At the time of winning the rare small role 4, the winning probability when the internal mode is low is set to 20%, the winning probability when normal is set to 30%, and the winning probability when set to high is set to 60%.
Returning to FIG. 10, in the next step S1009, regardless of the result of the AT lottery process A, the process moves to the precursor part P2 middle process, and the normal part P1 middle process ends.

On the other hand, when it is determined NO in step S1004, the process proceeds to step S1005, and the CZ lottery process A is executed. As shown in FIG. 8A, the CZ lottery process A is executed when the small combination 1 or the small combination 2 is won as a result of the internal lottery process, and the winning probability is set to 3%.
In the next step S1005, it is determined whether or not the CZ lottery process A has been won. If it is determined to be no, the process returns to step S1001, and the normal part P1 processing is continued. The process proceeds to CZ part P3 mid-process, and the normal part P1 mid-process is terminated.

(4) Precursor part P2
As described above, the sign part P2 is a part that starts from the next game regardless of the result when the AT lottery process A is executed in the normal part P1. For this reason, there are two types of the precursor part P2, that is, the case where the AT lottery process A of the normal part P1 is won and the transition is made, and the case where the transition is made.
In the precursor part P2, as shown in FIG. 6, an AT lottery process A for determining whether or not to grant the AT transition right according to the type of the winning combination in the internal lottery process (hereinafter referred to as an internal winning combination), CZ lottery process B for determining whether or not to shift to CZ part P3, point awarding process that affects the winning probability in CZ lottery process B, the warning counter reset process, and the winning probability in AT lottery process A A mode-up lottery process and a mode fall lottery process for changing the internal game mode for

Among the above processes, the AT lottery process A, the CZ lottery process B, the mode-up lottery process, and the mode drop lottery process are executed only when the AT transfer right has not yet been granted.
Further, the AT lottery process A, the mode-up lottery process, and the mode fall lottery process are the same as those of the normal part P1, and thus the description thereof is omitted.

Hereinafter, the flow of processing in the precursor part P2 in the slot machine 1 will be described with reference to FIGS.
In the precursor part P2 mid-process, first, in step S1101, a process of setting the number of games that should continue the precursor part P2 (hereinafter referred to as the precursor game number), the precursor counter, and the initial value of the points is performed.
The method of determining the number of precursor games is different between the case where the AT lottery process A of the normal part P1 is won and the transition to the precursor part P2 is made, and the case where the transition is made to the precursor part P2.

When winning the normal part P1 AT lottery process A and proceeding to the precursor part P2, as shown in FIG. 7B, the probability of setting the number of precursor games to 2-7 games is 1% respectively, the total probability The probability of setting 6% and 8 to 27 games is 2%, the total probability is 40%, the probability of setting 28 to 31 games is 10%, the total probability is 40% and the probability of setting 32 games is 14 respectively. % Is set.
That is, the number of precursor games is set to 2 games at the shortest and 32 games at the longest, and the probability of being set to 28 games or more is higher than the probability of being set to 27 games or less.

  On the other hand, if the AT lottery process A of the normal part P1 is deviated and the precursor part P2 is entered, the number of precursor games is set to 32 games.

  The initial value 32 is set in the precursor counter when the precursor part P2 is started. Further, as will be described later, when the rare part 1, rare part 2, rare part 3, or rare part 4 is won during the precursor part P 2, it is reset and the initial value 32 is reset. Except when the precursor counter is reset, the precursor counter is decremented by one for each game in the precursor part P2. Further, the current value of the precursor counter is displayed on the liquid crystal display device 30 during the precursor part P2.

  Since the precursor counter is different from the number of precursor games, it does not accurately represent the number of games until the end of the precursor part P2, but at that time the number of games corresponding to the value of the precursor counter exceeds the precursor part P2. Does not continue, and indicates the longest number of games that the sign part P2 may continue.

  Further, the number of points affects the winning probability in the CZ lottery process B described later, and is set to 1 at the start of the precursor part P2.

Returning to FIG. 11, in the next step S1102, an internal lottery process is executed, and in the next step S1003, the number of precursor games and the precursor counter are each subtracted by one.
In the next step S1104, it is determined whether or not the AT transfer right has already been granted. If NO is determined, the mode up lottery process is executed in step S1105 and the mode drop lottery process is executed in step S1106. Then, the process proceeds to step S1007. Also when it is determined as YES in step S1104, the process proceeds to step S1007.
Since the mode-up lottery process and the mode drop lottery process are the same as both processes in the normal part P1, description thereof will be omitted.

  In step S1107, it is determined whether or not the opportunity for the AT lottery process A is won. The AT lottery process A is triggered when the internal winning combination is a rare small combination 1, a rare small combination 2, a rare small combination 3, or a rare small combination 4, as shown in FIG. That is, it is equivalent to the normal part P1. Accordingly, in step S1107, if the internal winning combination is a rare combination 1, a rare combination 2, a rare combination 3, or a rare combination 4, it is determined to be yes, otherwise it is determined to be no.

If it is determined as YES in step S1107 and the AT transfer right has not yet been granted, AT lottery processing A is executed in S1108. Since the AT lottery process A is equivalent to the same process in the normal part P1, its description is omitted. If the AT transfer right has already been granted, step S1108 is skipped.
In the next step S1109, a sign game number change process and a sign counter reset process are executed.
The sign game number changing process is executed when winning in the AT lottery process A in step S1108 and when the AT transfer right is newly granted, or when the AT lottery process A in step S1108 is removed. In other words, if the AT transfer right has already been granted and the AT lottery process A in step S1108 is skipped, the current number of precursor games is maintained as it is without executing the precursor game number changing process. The

As shown in FIG. 7B, when the winning in the AT lottery process A in step S1108 is performed and the AT transfer right is newly granted, the initial game number setting process described in step S1101 is performed. Determine the number of precursor games.
In addition, even if the AT lottery process A in step S1108 is defeated, the number of precursor games is set to 32 games, as in the initial game number setting process described in step S1101.
Further, the sign counter is reset to 32 regardless of whether or not the AT lottery process A is executed in step S1108 and the result of the AT lottery process A when it is executed.

In the next step S1110, 1 is added to the point, and the process proceeds to step S1201. Also, when it is determined NO in step S1107, the process proceeds to step S1201.
Further, the current acquired number of points is displayed on the liquid crystal display device 30 in the precursor part P2.

  As shown in FIG. 12, in the next step S1201, it is determined whether or not the AT transfer right has already been granted. If NO is determined in step S1201, it is determined whether or not the number of precursor games is zero in step S1202. If NO is determined, the CZ lottery process B is determined YES in step S1203. In step S1206, the CZ lottery process C is executed.

As described above, the CZ lottery process B in step S1203 is the internal lottery process in the precursor part P2 as shown in FIG. 6 and FIG. 8B in a state where the AT transition right has not yet been granted in the precursor part P2. As a result, it is executed when the small combination 1 or the small combination 2 is won. The winning probability is set to be higher as the current number of points is larger.
The specific winning probability is 3% if the current number of points is 1 point, 6% if 2 points, 25% if 3 points, 40% if 4 points, 60 if 5 points %, 6 points are set to 70%, and 7 points are set to 80%.

  As described above, points are awarded when a rare small combination 1, a rare small combination 2, a rare small combination 3, or a rare small combination 4 is won in the precursor part P2. In addition, since winning of these rare small roles 1 to 4 is also an opportunity of AT shift lottery processing A, even if the result of AT shift lottery processing A is lost, points are awarded and CZ lottery processing B is performed. The benefit that the winning probability is improved.

  In addition, the CZ lottery process A is executed when the small part 1 and the small part 2 in the normal part P1 are won. However, during the sign part P2, the CZ lottery process A is performed when the small part 1 and the small part 2 are won. Instead, the CZ lottery process B is executed. As shown in FIGS. 8A and 8B, the winning probability in the CZ lottery process B is 3% equivalent to the CZ lottery process A when the number of points is 1 point, but it is 2 points or more. Is higher than the CZ lottery process A, so the CZ lottery process B in the precursor part P2 is more likely to win and shift to the CZ part P3 than the CZ lottery process A in the normal part P1. .

On the other hand, as described above, the CZ lottery process C in step S1206 is performed when the number of precursor games becomes zero in the state where the AT transition right has not yet been granted during the precursor part P2, that is, at the end of the precursor part P2. Executed.
As shown in FIG. 8C, the winning probability in the CZ lottery process C is set to be higher as the current number of points is larger. The specific winning probability is 5% if the current number of points is 1 point, 9% if 2 points, 30% if 3 points, 45% if 4 points, 75 if 5 points %, 6 points are set to 90%, and 7 points are set to 100%.
As can be seen by comparing FIG. 8B and FIG. 8C, the winning probability in the CZ lottery process C is set higher than the winning probability in the CZ lottery process B for any number of points. .

Returning to FIG. 12, after executing the CZ lottery process B in step S1203, it is determined whether or not the winning is made in step S1204. If the determination is yes, the process in the CZ part P3 is started in step S1205. Then, the processing during the precursor part P2 is finished. On the other hand, if NO is determined in step S1204, the process returns to step S1102, and the pre-part P2 processing is continued.
In addition, after executing the CZ lottery process C in step S1206, it is determined whether or not the winning is made in step S1207. If it is determined that the answer is YES, the process in the CZ part P3 is started in step S1205, The process in part P2 is terminated. On the other hand, if NO is determined in step S1207, the normal part P1 process is started in step S1208, and the precursor part P2 process is ended.

  Returning to step S1201, if it is determined yes in this step, it is determined whether or not the number of precursor games is zero in step S1209. If it is determined that there is yes, the state shifts to the AT state and the precursor part P2 is in progress. The process ends. On the other hand, if NO is determined in step S1209, the process returns to step S1102, and the pre-part P2 processing is continued.

FIG. 14A shows an example of an effect screen displayed on the liquid crystal display device 30 during the precursor part P2. As described above, the current sign counter value is displayed in the sign counter display area 30a in the lower right corner, and the number of points currently acquired is displayed in the lower point display area 30b. Seven rhombus-shaped icons are displayed in the point display area 30b, and the number of points currently acquired is displayed by lighting the number of icons corresponding to the number of points. FIG. 14A shows a case where the number of points currently acquired is one point.
(5) CZ part P3
The CZ part P3 is composed of a fixed number of games of 20 games. In CZ part P3, a score is given according to the internal lottery result of each game, and after completing 20 games, that is, at the end of CZ part P3, transition to the AT state based on the total score obtained during CZ part The AT lottery process B for lottering whether or not to perform is executed. When the AT lottery process B is won, the next game shifts to the AT state. When the AT lottery process B is missed, the next game shifts to the normal part P1.

Hereinafter, the flow of processing in the CZ part P3 in the slot machine 1 will be described with reference to FIG.
First, in step S1301, the number of CZ games and the initial value of the score are set. Specifically, 20 is set for the number of CZ games and zero is set for the score.
After the internal lottery process is executed in the next step S1302, a score lottery process corresponding to the result of the internal lottery process is executed in the next step S1303. Specifically, as shown in FIG. 9A, when the internal winning combination is a replay, push order small combination or loss, the score to be given is 0 point with a probability of 50%, 1 point with a probability of 50% And decide. When the internal winning combination is a small combination 1 or a small combination 2, the score to be given is determined to be 2 points with a probability of 80% and 3 points with a probability of 20%. When the internal winning combination is a rare small combination 1 or a rare small combination 2, the score to be awarded is determined as 3 points with a probability of 80% and 5 points with a probability of 20%. When the internal winning combination is a rare small combination 3 or a rare small combination 4, the score to be awarded is determined as 5 points with a probability of 80% and 7 points with a probability of 20%.

  Returning to FIG. 13, in the next step S1304, a score addition process for adding the score determined in the score lottery process in step S1303 to the current score is executed. In the next step S1305, 1 is subtracted from the number of CZ games. In the next step S1306, it is determined whether or not the number of CZ games is zero. If NO is determined in step S1306, the process returns to step S1302, and the processing in the CZ part P3 is continued. On the other hand, if YES is determined, that is, at the end of the CZ part P3, the AT lottery process B is determined in step S1307. Execute.

  In the AT lottery process B, it is determined whether or not to shift to the AT state with the winning probability corresponding to the score acquired during the CZ part P3. Specifically, as shown in FIG. 9B, when the score is 0 point or 10 points or more, it is determined to shift to the AT state with a probability of 100%. Further, when the score is 1 to 9, it is determined to shift to the AT state with a probability of score × 10%. For example, in the case of 5 points, the winning probability is 50%.

  Returning to FIG. 13, in the next step S1308, it is determined whether or not the AT lottery process B has been won. If it is determined to be yes, the state is shifted to the AT state. The middle process is started and the middle process of the CZ part P3 is finished.

  FIG. 14B shows an example of an effect screen displayed on the liquid crystal display device 30 during the CZ part P3. The current remaining CZ game number is displayed in the remaining CZ game number display area 30c in the lower left corner, and the currently acquired score is displayed in the score display area 30d in the lower right corner.

  As described above, according to the slot machine 1 of the present invention, when one of the rare small combination 1 to the rare small combination 4 is won in the normal part P1, the precursor part P2 is started. Since Rare Small Role 1 to Rare Small Role 4 are the triggers of AT lottery processing A, the start of precursor part P2 can increase the expectation for winning in AT lottery processing A, and the player Since it becomes impossible to leave the slot machine until the end of the precursor state where the result of the lottery process A becomes clear, there is an effect of contributing to an improvement in the operation of the slot machine as a result.

  Moreover, even if the AT lottery process A in the normal state is deviated and the precursor part P2 is shifted to, the AT lottery process A is performed when the rare small role 1 to the rare small role 4 are won, and the mode-up lottery process is performed when winning other than the replay role. Since the mode drop lottery process is executed at the time of replay winning combination, it is equivalent to the normal part P1, and therefore, the expectation degree for the winning in the AT lottery process A in the precursor part P2 is equivalent to the precursor part P1. Therefore, even if the player deviates from the AT lottery process A in the normal part P1 and shifts to the precursor part P2, the player is not disadvantaged with respect to the winning in the AT lottery process A.

In addition, during Precursor Part P2, points are awarded regardless of the result of AT lottery process A when Rare Minor 1 to Rare Minor 4 are elected. It is possible to improve the degree of expectation for winning in the CZ lottery process B executed at the time of winning the winning combination 1 or the small combination 2 and winning in the CZ lottery process C executed at the end of the precursor part P2.
As shown in FIGS. 8A and 8B, the trigger of the CZ lottery process B is the same as the CZ lottery process A in the normal part P1, when the small role 1 or the small role 2 is won, and the CZ lottery The winning probability in process B is equal to the winning probability of CZ lottery process A in normal part P1 even if the point is the lowest one point. If the number of points is 2 or more, CZ in normal part P1 Since it is higher than the winning probability of the lottery process A, the expected value for the shift to the CZ part P3 is higher in the precursor part P2 than in the normal part P1. Thereby, not only the expectation for the winning in the AT lottery process A but also the expectation for the transition to the CZ part P3 can be enhanced by the transition to the precursor part P2.

  Further, at the end of the precursor part P3, if the AT transition right has already been granted, the state shifts to the AT state, and if the AT transition right has not been granted, the CZ lottery process C is executed. As shown in FIGS. 8B and 8C, the winning probability in the CZ lottery process C is higher than the winning probability in the CZ lottery process B executed during the precursor part P3 at any number of points. At the end of the precursor part P3, it is executed regardless of the internal lottery result. Therefore, at the end of the precursor part P2, notification of whether or not to shift to the AT state and notification of whether or not to shift to the CZ part P3 are executed, and the player's expectation is enhanced to the maximum. It can be made.

  In addition, if the AT lottery process A is not completed during the precursor part P2 to which the AT transfer right has not yet been granted, the number of precursor games will be reset to the initial value of 32 games. The precursor part P2 has a relatively high expectation level for the transition to the CZ part P3 than the normal part P1, and by prolonging the predictor part P2, there is also an opportunity to acquire points that can further increase the expectation level for the transition to the CZ part P3. For this reason, it is desirable for the player who has not yet been granted the AT transfer right to prolong the precursor part P2.

  On the other hand, in the precursor part P2 to which the AT transition right has already been granted, the number of precursor games determined when the AT transition right has been granted is not changed, as shown in FIG. When 32 games at the maximum are digested from the games won in the AT lottery process A, the precursor part P2 is finished and the state is shifted to the AT state. Therefore, the transition to the AT state is not postponed further due to the change in the number of precursor games after the AT transition right is granted.

  Further, even in the precursor part P2 to which the AT transfer right has already been granted, the point addition process at the time of winning the rare small combination 1 to the rare small combination 4 and the reset process of the precursor counter are executed. That is, as shown in FIG. 14A, the parameters displayed on the liquid crystal display device 30 are processed in the same manner regardless of whether or not the AT transfer right is granted. It is impossible to detect whether or not. Accordingly, the player's sense of expectation for the AT state transition can be maintained until the sign part P2 ends.

Further, in the CZ part P3, it is determined whether or not to start the AT state in the AT lottery process B having a logic different from the AT lottery process A in the normal part P1 and the precursor part P2.
Specifically, since the AT lottery process A in the regular part P1 and the precursor part P2 is not executed unless the rare small combination 1 to the rare small combination 4 are won, it may not be executed over a long period if bad luck.
On the other hand, the AT lottery process B for the CZ part P3 is always executed at the end of the CZ part P3, and as shown in FIGS. 9A and 9B, any of the internal lottery results can be obtained during the CZ part P3. Even in this game, a so-called specification that does not cause wasteful withdrawal, which may be scored, is adopted.
And it is the specification that the winning probability basically increases as the total of points given according to the internal lottery result of each game in the CZ part P3 over 20 games increases.

  In addition, the CZ part P3 has a higher AT transition expectation than the normal part P1 and the predictor part P2, and the probability of directly transferring to the CZ part P3 is as follows: normal part P1 <precursor part P2 <precursor part P2 It is set. That is, as the game progresses, the specification that the expected degree of transition to the CZ part P3 gradually increases is adopted, so that the player's willingness to continue can be maintained until the end of the precursor part P2. Furthermore, even if the transition to the AT state is not performed at the end of the precursor part P2, if the CZ part P3 having the highest AT transition expectation is started, the player's willingness to capture can be increased again. Since the player cannot leave the slot machine until the CZ part P3 is completed, an effect of contributing to an improvement in operation can be obtained.

In addition, each part structure of this invention is not restricted to the said embodiment, A various deformation | transformation is possible within the technical scope as described in a claim.
For example, in the slot machine 1 of this embodiment, 1 is added to the point regardless of whether or not the AT transition right has already been granted at the time of winning the rare small combination 1 to the rare small combination 4 in the precursor part P2. However, instead of this, the number of points to be added may be selected by lottery according to whether or not the AT transfer right has already been granted. Similarly, although the initial point number at the start of the precursor part P2 is 1 regardless of whether or not the AT transition right has already been granted, whether or not the AT transition right has already been granted for the initial point number as well. Depending on the situation, a lottery may be selected. In this case, by setting the expected value of the number of points to be added and / or the initial number of points to be different depending on whether or not the AT transfer right is granted, the player can increase the number of points, Based on the initial number of points, it is possible to infer whether or not the AT transfer right is granted.

  In addition, in the slot machine 1 of this embodiment, the execution trigger of the CZ lottery C is set at the end of the precursor part P2, but instead of several games before the game where the precursor part P2 ends. CZ lottery C may be executed in a range, for example, a range of five games including an end game, and CZ lottery B may be executed in other cases. In short, by setting the execution condition of the CZ part lottery C in association with the end condition of the precursor part P2, an effect equivalent to the case of executing the CZ lottery C at the end of the precursor part P2 can be obtained.

  Furthermore, various lotteries that affect the transition to the AT state, such as AT lottery process A, AT lottery process B, mode up lottery process, mode fall lottery process, CZ lottery process A, CZ lottery process B, and CZ lottery process C The process may be executed on the main control unit 100A side or may be executed on the effect control unit 100B side. When executing on the main control unit 100A side, information relating to the results of various lottery processes may be transmitted to the effect control unit 100B each time, and when executing on the effect control unit 100B side, the main control unit 100A. Information relating to the internal lottery result is transmitted to the game effect control unit 100B from the side, and various lottery processes may be executed on the effect control unit 100B side according to this information.

  Furthermore, in the slot machine 1 of the present embodiment, no process of granting any privilege is performed during the precursor part P2 in which the AT transfer right has already been granted, but depending on the result of the internal lottery process, You may comprise so that. For example, as the privilege to be given, shortening the number of precursor games, adding the initial number of AT games, and the like can be mentioned. Moreover, as an opportunity which grants a privilege, the case where a prize grant lottery at the time of winning of rare role 1-rare role 4 is won, etc. are mentioned.

  The present invention can be applied to a slot machine.
