Description

  The present invention relates to a gaming machine and, for example, relates to a technique suitable for use in improving the sense of expectation by making it easier to win a big hit depending on time.

  As a conventional slot machine, a lottery of each game role is performed in a normal game, and when a special role is won, reel control that can align the winning symbol (for example, “7”) of the special role on the effective line. It is known that when the winning symbols of special roles are aligned on the active line, the game shifts from the normal game to the special game. As this special game, for example, a game such as BB (Big Bonus) or RB (Regular Bonus) is known, and many medals can be obtained at one time.

  In addition, recently, when a special role is won by a lottery of a role, the BB that has been stocked inside once and does not immediately shift to a special game and meets certain stipulated conditions (for example, the stipulated number of games played) is stocked. There is known a slot machine having a stock function in which RB and RB are released to shift to a special game.

JP 2005-95296 A

  In order to win a lot of medals, the player chooses a table that plays a game by predicting a high setting table while studying in magazines, etc. There was a problem that the interest would fade if we understood that it was not done.

  In order to win many BBs and RBs, the player predicts a table with a high setting and selects a gaming table. As a result, a table with a low setting such as a table with a low number of winning BBs or RBs in the past. Will be left unattended. On the other hand, for a player who starts playing in the evening or at night, such as a salaried worker, he can only play on a stand that seems to be left in this way, and it is difficult to play on a high setting stand. There was a problem.

  Further, in the slot machine having the stock function as described above, it is difficult to predict the setting only by the release probability of BB or RB, and the winning probability of a specific role (for example, cherry or plum) that is one of the winning roles. Also, there may be a setting difference in the release tendency of BB and RB, etc., and it is difficult to predict the setting unless you are an expert in slot machines. For example, for beginners who have just started playing slot machines, high settings There was a problem that it was more difficult to grab the table.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a sense of expectation even when a game is played on any platform.

  The gaming machine of the present invention is a lottery means for performing a lottery or a lottery for a transition between a plurality of gaming states, and a plurality of tables used by the lottery means at the time of lottery. A plurality of tables having different winning probabilities, time counting means for measuring time, and lottery state switching means for switching the plurality of tables used by the lottery means in the lottery at the time measured by the time measuring means. It is characterized by.

  As described above, the gaming machine of the present invention has a plurality of tables each having different winning probabilities for the transition to the special gaming state, and the table used for the lottery is switched based on the counted time. Is controlled. As a result, even if a game is played with a high setting, it becomes difficult to suddenly shift to the special gaming state, or a table that has been thought to be set to a low level suddenly shifts to the special gaming state frequently. Therefore, since it becomes more difficult to predict the setting, the player can focus on the analysis of the gaming machine, and the preference can be further enhanced.

  In the gaming machine according to the present invention, the winning probabilities of special combinations that are one of the winning combinations included in the plurality of tables are different. As a result, even if a game is played on a table with a low setting, a special role can be won many times as in a high setting depending on the time of day. Therefore, even if a player has played a game with a low number of special roles such as BB or RB in the past, he hopes that he will win the special role over and over again as the high setting, You can play games while inflating.

  In the gaming machine according to the present invention, the plurality of tables wins the transition to the special game state by winning the winning probability of the specific combination that is one of the winning combinations included in the plurality of tables. At least one of the probabilities is different. As a result, specific roles can be easily arranged depending on the time, the opportunity to shift to the special gaming state increases, and more tension can be given to the player. In addition, depending on the time, it becomes easier to cancel stock when specific roles are gathered, and the tension and expectation when specific roles are gathered can be expanded more greatly.

  In the gaming machine of the present invention, it is possible to set a time for switching a plurality of tables in accordance with an operation of an operating member attached to the gaming machine. Thereby, for example, when a store wants to gather a specific customer segment (for example, a company employee returning home), it is possible to easily shift to a special gaming state at a specific time. Therefore, a player who can play a game only at a specific time can play a game with a greater expectation.

  In the gaming machine of the present invention, it is possible to set a time for switching a plurality of tables at random. Therefore, for example, it is difficult for an expert to predict the setting, and it is also difficult to predict a time zone in which a big hit is likely to be released. Therefore, even a beginner has more opportunities to play a game on a high setting game machine.

  According to the present invention, since it becomes more difficult to predict the setting, the player can concentrate on the analysis of the gaming machine, and the preference can be further enhanced.

The setting change switch 83 is a switch operated when changing the setting related to the probability and the payout.

  The time setting switch 84 is a switch for setting the time at which the table is switched, and it is possible to set the time manually or to set the time automatically and randomly. The set time is stored in a switching time setting unit 104 in FIG. 3 to be described later.

(Power supply board 13)
A setting change enabling switch 91, a power switch 92, a hopper device 93, and a power device 94 are connected to the power device board 13. The setting change enable switch 91 is a switch that is operated when a setting change using the setting change switch 83 is enabled. That is, the setting change using the setting change switch 83 can be performed only when the setting change enable switch 91 is in the ON state. The power switch 92 is a switch for switching on / off the power supply device 94. The hopper device 93 is a device for storing and paying out medals, and pays out a predetermined number of medals from the stored medals to the player based on an instruction from the main CPU 51 via the power supply device board 13. .

  Next, a functional configuration of the main control board 50 will be described. FIG. 3 is a functional block diagram showing a functional configuration of the main control board 50. In the present embodiment, for example, the following units 101, 103, 106, 107, 108, and 109 are configured from programs recorded in the main CPU 51 and the ROM 52. For example, the RAM 53 has the following flag information storage unit 105 and A switching time storage unit 104 is provided, and data of the following lottery table 102 is stored in the ROM 52, for example.

(Role lottery section 103)
The role lottery unit 103 draws a role (special role, small role, replay, etc.). Here, the special combination is a combination that is a game different from the normal game and is shifted to a plurality of special games that are advantageous to the player. A small role is a role of paying out a number of medals to a player according to the type of the small role. Replay is a role that gives a player the right to replay while maintaining the number of medals inserted in the previous game.

  Further, the role lottery unit 103 obtains one random number after generating a random number internally for each game, refers to the lottery table 102 stored in the ROM 52, and based on the area to which the obtained random number belongs, The presence / absence of a winning combination and the winning combination are determined.

  That is, the role lottery unit 103 generates random numbers in a predetermined area (0 to 65535 in decimal notation), for example, and when a predetermined condition is satisfied, for example, when the start switch 41 is operated, Get the numeric value. In the lottery table 102, a special role winning area, a small role winning area, a replay winning area, a non-winning area (losing) area, and the like are set at a predetermined ratio with respect to random numbers that can be acquired by the role lottery unit 103. ing. In other words, the lottery table defines the relationship between random numbers and each combination. For example, a random value (a + α) is assigned to a special combination (BB) from a random value (a), From the random value (a + α + 1), another random value (a + α + 1 + β) is assigned to the special role (RB), and the random value is similarly assigned to the small role winning area and the like. Then, the winning combination in the area including the random value acquired by the winning lottery unit 103 becomes the winning winning combination as a result of the winning lottery. Details of the lottery table 102 will be described later with reference to FIG.

  Then, the combination lottery unit 103 compares the acquired random number value with the lottery table 102 to determine an area to which the random value belongs, and determines a combination corresponding to the area to which the random value belongs. For example, when the extracted random number value belongs to the special combination winning area, it is determined that the special combination is won, and when it belongs to the non-winning area, it is determined to be lost. If any combination is won, the flag for the combination is turned on.

(Control unit 101)
The control unit 101 controls the operation timing of the combination lottery unit 103, a reel control unit 106 and a winning determination unit 107, which will be described later. For example, on the condition that the start switch 41 is operated, the control unit 101 causes the combination lottery unit 103 to perform combination lottery, causes the reel control unit 106 to start rotating the reel group 31, and sets the stop switch The reel control unit 106 performs stop control of the reel group 31 on the condition that the group 42 has been operated, and further causes the winning determination unit 107 to perform a prize determination on the condition that the reel group 31 has stopped. Further, the control unit 101 instructs the reel control unit 106 to transmit to the sub-control board 60 reel stop position information described later and the payout control unit 109 to transmit payout medal number information described later. Further, the control unit 101 reads the current time from the time counting unit 72, compares it with a time stored in a switching time storage unit 104 described later, and performs control to switch the lottery table 102 if they match. The operation of the control unit 101 is not limited to these.

(Switching time storage unit 104)
The switching time storage unit 104 stores a time for switching the lottery table 102. The time recorded in the switching time storage unit 104 is read out by the control unit 101 for collation processing with the time counted by the time counting unit 72.

(Flag information storage unit 105)
The flag information storage unit 105 stores the type of the winning combination and the fact that the flag is turned on when a flag for any combination is turned on by the lottery result of the combination lottery unit 103.

(Reel control unit 106)
The reel control unit 106 controls rotation and stop of the reel group 31 (reels 31L, 31C, and 31R) based on an instruction from the control unit 101. More specifically, the reel control unit 106 has a gaming state (for example, a normal gaming state, a special gaming state, etc.), a result of lottery by the combination lottery unit 103, and a stop switch group 42 (stop switches 42L, 42C, and 42R). Based on the operated timing or the like, the stop positions of the reels 31L, 31C and 31R are determined, and the driving of the stepping motor is controlled to stop the rotation of the reels 31L, 31C and 31R at the determined positions.

  For example, as a result of the lottery by the part lottery unit 103, when no part is won, the reels 31L, 31C, and 31C are arranged so as not to stop the combination of symbols of any part on the activated effective line. A stop position of 31R is determined. On the other hand, when any combination is won, the stop positions of the reels 31L, 31C, and 31R are determined so that the combination of symbols of the winning combination is stopped on the activated effective line.

  In particular, when the special combination is won in the game, the reels 31L, 31C, and 31R are within the range of the stop control so that the combination of the special combination symbols is stopped on the active line that is enabled ( For example, within 4 symbols), pull-in control is performed so that the symbols related to special roles are aligned as much as possible. However, even if the special combination is won, when the small combination or replay is selected, the reels 31L, 31C, and 31C, so that the combination of the special combination symbols does not stop on the activated active line. A stop position of 31R is determined. Such control when stopping the reels 31L, 31C and 31R may be performed using a reel control table.

  In addition, when the control unit 101 instructs the reel control unit 106 to transmit reel stop position information to the sub-control board 60, the reels indicating the stop positions of the reels 31L, 31C, and 31R determined as described above. Stop position information is transmitted to the sub-control board 60.

(Winning determination unit 107)
The winning determination unit 107 determines whether or not a combination of symbols in the active line group 22 is arranged in any of the active lines that are active, and if there is an in-line combination, It is determined that the prize has been won. At this time, the winning determination unit 107 determines, for example, the symbol positioned on the effective line by detecting the angle, the number of steps, or the like when the stepping motor is stopped, and based on this, determines the presence / absence of a winning combination. . When a table is used for control when stopping the reels 31L, 31C, and 31R, the winning determination unit 107 does not determine the combination of symbols after the reels 31L, 31C, and 31R actually stop. Alternatively, when the reel control unit 106 determines the stop position of the reel group 31 using a table, the combination of symbols that stop on the effective line may be determined.

(Special game control unit 108)
As a result of the determination by the winning determination unit 107, the special game control unit 108 controls the special game until the predetermined end condition is satisfied from the next game when the symbols related to the special role are aligned on the active line. . For example, the special game control unit 108 causes the reel control unit 106 to perform reel control for special games according to the lottery result of the role lottery unit 103 during the special game, or causes the sub control board 60 to perform special game effects. Or let it be done.

(Payout control unit 109)
The payout control unit 109 causes the hopper device 93 to pay out medals corresponding to the winning combination as a result of the determination by the winning determination unit 107. Also, when there is an instruction from the control unit 101 to transmit the payout medal number information to the sub control board 60, the payout control unit 109 displays payout medal number information indicating the number of medals paid out during the game. 60 is transmitted.

  Next, a functional configuration of the sub control board 60 will be described. FIG. 4 is a functional block diagram showing a functional configuration of the sub control board 60. In the present embodiment, for example, the effect pattern selection unit 201 is configured from a program recorded in the sub CPU 61 and the ROM 62, and the program recorded in the sub CPU 61 and the ROM 62, and the image control processor 64 and the image data ROM 64. The effect control unit 202 is composed of a program or the like recorded therein.

(Production pattern selection unit 201)
The effect pattern selection unit 201 selects an effect pattern according to the gaming state. Specifically, the effect pattern selection unit 201 receives a signal from the role lottery unit 103 of the main control board 50 and selects an effect pattern according to the winning combination or the like, or a winning determination unit 107 of the main control board 50. In response to a signal from the special game control unit 108, an effect pattern corresponding to a winning combination or a gaming state is selected.

(Production control unit 202)
The effect control unit 202 displays an effect image corresponding to the effect pattern selected by the effect pattern selection unit 201 on the effect display device 40. In addition, the effect control unit 202 controls the sound source circuit 67 so that a sound signal is generated by the sound source circuit 67, amplified by the amplifier 68, and then output from the speaker 71.

FIG. 5 is a diagram showing an example of the lottery table 102 used in the present embodiment.
FIG. 5A shows the configuration of the normal table 501 used in the normal state, and FIG. 5B shows the configuration of the high-probability table 502 having a higher ratio of special roles (BB and RB) than the normal table. The lottery table 102 is composed of these two tables.

  The normal table 501 is composed of a winning combination of a special role consisting of BB510 and RB511, and cherry A512, cherry B513, watermelon 514, bell 515, replay 516, and loser 517, and the high probability table 502 is similarly configured. ing. However, the high probability table 502 has a higher ratio of the winning area for the special role than the normal table 501 and is easier to win for the special role than the normal table 501. Although details will be described later, the normal table 501 and the high probability table 502 are switched at an arbitrary time.

  Further, the cherry A512 refers to a cherry that is controlled so that the cherry symbol included in the left reel 31L in FIG. 1 stops at the line 22a, and the cherry B513 refers to the cherry included in the left reel 31L. It refers to the cherry that is controlled so that the symbol stops at the lines 22b and 22c. Cherry A512 and Cherry B513 have different payout numbers and different flags.

  Next, the operation of the slot machine 1 according to the present embodiment configured as described above will be described. FIG. 6 is a flowchart showing control by the main control board 50, and FIG. 7 is a flowchart showing control by the sub control board 60.

  In FIG. 6, when the player inserts a medal or presses the bet switch 43 (step S601), the control unit 101 determines whether or not the player is in a three-ply state (step S602). As a result of the determination, if the number is not three (step S602 / NO), the process returns to step S601 to wait for insertion of medals or pressing of the bet switch 43. If it is in the state of three sheets (step S602 / YES), the operation of the start switch 41 is awaited.

  When the control unit 101 detects that the start switch 41 is turned on (step S603), the combination lottery unit 103 performs a combination lottery process (step S604). On the other hand, if the start switch 41 is not operated by the player and the control unit 101 cannot detect that the start switch 41 is turned on, the process proceeds to step S603 until it is detected that the start switch 41 is turned on. Repeat the detection process.

  In the combination lottery process in step S604, the combination lottery unit 103 acquires a random number, and compares the acquired random number with the lottery table 102 to perform a combination lottery process. As a result of the lottery, if any combination is won, the flag of the combination is turned on in the flag information storage unit 105. The lottery result by the combination lottery unit 103 is transmitted to the sub-control board 60 through the I / F circuit 54 as winning combination information (step S605).

  The reel control unit 106 determines whether any one of the stop switch groups 42 has been operated (step S606). When any one of the stop switches is operated (step S606 / YES), reel control is performed so that the winning combination can be won, and the rotating reel corresponding to the operated stop switch is stopped (step S607). ). If the winning combination is won in the combination lottery process in step S604, the reel control unit 106 performs reel control corresponding to the losing in step S607.

  Subsequently, the reel control unit 106 determines whether all the stop switches are operated and all the reels are stopped (step S608). If all the reels have not been stopped yet (step S608 / NO), the processing from the detection processing of presence / absence of the stop switch operation in step S606 is repeated.

  When all the reels stop (step S608 / YES), the winning determination unit 107 determines the presence or absence of winning based on the combination of symbols arranged on the activated effective line (step S609). As a result, if there is any winning (step S609 / YES), winning processing corresponding to the winning combination is executed (step S610). That is, when the winning combination is a special combination, the special game control unit 108 controls the special game from the next game until the predetermined end condition is satisfied.

  On the other hand, if it is determined in step S609 that there is no winning (step S609 / NO), the winning process is not performed and the process ends. During the special role game, the special game control unit 108 provides the player with a game state corresponding to the big bonus (BB) game or the regular bonus (RB) game that is the special role. The reel control during the special game is performed, or the sub control board 60 is caused to perform the special game effect. When the specified number of games of the big bonus (BB) game or the regular bonus (RB) game is completed, a process of shifting to the normal game is performed.

  If the winning combination is not a special combination, if the flag of the special combination is stored in the on state in the flag information storage unit 105, the storage state of the flag in the flag information storage unit 105 is carried over to the next game.

  When the winning combination is replay, the winning determination unit 107 causes the control unit 101 to carry a bet (the number of bets) on the game to the next game. On the other hand, when the winning combination is neither a special combination nor a replay, the payout control unit 109 causes the hopper device 93 to pay out the number of medals corresponding to the winning combination.

Next, the operation of the sub control board 60 will be described with reference to FIG.
In FIG. 7, the effect pattern selection unit 201 determines whether or not a lottery result has been received from the main control board 50 (step S701), and if received, whether or not the effect pattern selected last time continues. Is determined (step S702). As a result of this determination, if it continues (step S702 / YES), the process proceeds to step S703, and the effect control unit 202 outputs the continuation of the effect based on the previous effect pattern to the effect display device 40. If the effect pattern is not continued (step S702 / NO), the effect pattern selection unit 201 selects an effect pattern based on the lottery result (step S704). Next, the effect control unit 202 outputs an effect based on the selected effect pattern to the effect display device 40.

FIG. 8 is a flowchart showing a switching process procedure of the lottery table 102 by the control unit 101 of the main control board 50 in the present embodiment.
In FIG. 8, the control unit 101 reads a set time at which the next table is switched from the switching time storage unit 104 (step S801). Next, the current time is read from the time counting unit 72 (step S802), and it is determined whether or not it matches the set time read from the switching time storage unit 104 (step S803). If the result of this determination is that they do not match (step S803 / NO), the process returns to step S802. When it is recognized that they match (step S803 / YES), the lottery table 102 is switched (step S804). That is, the normal table 501 shown in FIG. 5 is switched to the high probability table 502, or the high probability table 502 is switched to the normal table 501. When this switching is completed, the same processing is repeated.

  As described above, in this embodiment, since the lottery table 102 varies depending on the time even in the same slot machine, even a table with a small number of special games won can easily be a big hit. The taste can be increased.

  In the present embodiment, the lottery table 102 is described in two stages. However, for example, switching may be performed using a table having three or more stages such as low probability, normal, and high probability. In this case, the tables may be switched in a regular order, or the tables may be switched in an irregular order.

(Second Embodiment)
In the present embodiment, description will be made using a slot machine (stock machine) having a stock function. The appearance and hardware configuration of the slot machine are the same as the configurations shown in FIGS. 1 and 2 in the first embodiment, and thus the description thereof is omitted. The functional configuration of the sub control board is also the same as the configuration shown in FIG. 4 in the first embodiment, and a description thereof will be omitted.

FIG. 9 is a functional block diagram showing a functional configuration of the main control board 50 in the present embodiment.
In the present embodiment, for example, the following units 101, 106, 107, 108, 109, 110, 112, and 113 are configured from the programs of the main CPU 51 and ROM 52. For example, the following storage units 104, 105 are stored in the RAM 53. For example, the ROM 52 stores the following data in the normal game lottery table 121 and internal lottery table 122 and data in the release table 123 (lottery table 102). In the present embodiment, description of the same functions as those in the first embodiment will be omitted.

(Role lottery section 103)
The role lottery unit 103 obtains one random number after internally generating a random number for each game. Further, it functions as a lottery table changing means for selecting one appropriate table from the normal gaming table 121 and the internal lottery table 122 stored in the ROM 52, and the area to which the acquired random number in the selected lottery table belongs. Based on the above, the presence / absence of a winning combination and the winning combination are determined. In addition, you may make it provide the lottery table change means which fulfill | performs the said function separately from the role lottery part 103. FIG.

(Flag information storage unit 105, special role winning possible number storage unit 111)
The flag information storage unit 105 stores the type of the winning combination and the fact that the flag is turned on when a flag for any combination is turned on by the combination lottery unit 103. Further, the flag information storage unit 103 includes a special role winning possible number storage unit 111. The number-of-special winnings storage unit 111 is a number obtained by subtracting the number of winnings for special roles from the number of winning special roles in the past, that is, the number of possible special winnings that can be won in special games (this The number of times that the player can win in a later game is stored. As described above, since special roles include two types of roles, BB and RB, the special role winning count storage unit 111 individually indicates the number of BB special roles that can be won and the number of RB special roles that can be won. To remember.

(Special part winning possible number addition part 110)
The special part winning possible number adding part 110 is stored in the special part winning possible number storing part 111 when the special part winning flag is turned on by the part lottery part 103, that is, when a special part is won. “1” is added to the number of possible winning combinations (the number of stocks is increased by “1”). That is, if it is determined that BB has been won, the number of BB special role winnings that can be won is incremented by “1”, and if it is determined that RB has been won, the number of RB special role winnings that can be won is incremented by “1”.

(Special part winning possible number subtraction part 113)
When the special combination winning number subtraction unit 113 determines that the special combination has been won by the winning determination unit 107, the special combination winning number subtraction unit 113 subtracts “1” from the number of possible special combination winnings stored in the special combination winning number storage unit 111. (Release only “1” in stock). That is, when it is determined by the winning determination unit 107 that the special role BB has won, “1” is subtracted from the number of BB special roles that can be won, and the winning determination unit 107 determines that the special role RB has won. If it is, “1” is subtracted from the number of RB special role winnings possible.

(Release lottery section 112)
The cancellation lottery unit 112 performs a lottery to determine whether or not to release (release) BB or RB stocked in the special combination winning possible number storage unit 111 when a flag for a specific combination (watermelon or the like) described later is established. . In other words, a lottery to shift to a special game is performed here.

(Release table 123)
The release lottery unit 112 is a table used when lottery is performed to determine whether to release the stocked BB or RB, and details will be described later with reference to FIG.

(Reel control unit 106)
As a result of the lottery by the part lottery part 103, the reel control unit 106 determines which combination of symbols on the active line that is valid when the replay B, lose, or special part flag described later in FIG. 10 is established. Also, the stop positions of the reels 31L, 31C, and 31R are determined so as not to stop. On the other hand, when any combination is won, the stop positions of the reels 31L, 31C, and 31R are determined so that the combination of symbols of the winning combination is stopped on the activated effective line.

  Further, in the normal gaming state, the reel control unit 106 performs reel control so that even if a special combination is won in the lottery, a special combination is not won, and a state in which the stocked special combination can be released has been entered. In this case, reel control is performed so that the special combination can be won. Such control when stopping the reels 31L, 31C and 31R may be performed using a reel control table.

(Lottery table 102)
The above-described normal game lottery table 121 is the same table as FIG. 5, and includes a normal table 501 and a high probability table 502. On the other hand, FIG. 10 is a diagram showing the configuration of the internal / lottery table 122, and shows the configuration of the internal / lottery table 122 used by the role lottery unit 103 during replay time (when stock is present). The internal medium lottery table 122 includes a normal internal medium lottery table 1001 in a normal state and a high probability internal medium lottery table 1002 with a high probability of shifting to a special game. In the present embodiment, the lottery table 102 includes a total of four tables: a normal table 501 and a high probability table 502 used during normal games, a normal internal medium lottery table 1001 and a high probability internal medium lottery table 1002 used during replay time. Consists of

  The normal internal lottery table 1001 is composed of a special role consisting of BB1010 and RB1011 and winning areas of Cherry A1012, Cherry B1013, Watermelon 1014, Bell 1015, Replay A1016, Replay B1017, Loss 1018, and high probability internal The middle lottery table 1002 is similarly configured. However, the high-probability internal / lottery table 1002 has a higher percentage of winning areas for specific roles (Cherry A1012, Cherry B1013, Watermelon 1014, Loss 1018) than the regular internal / lottery table 1001, and is higher than the regular internal / lottery table 1001. It is easier to win special roles. Although details will be described later, the normal internal / lottery table 1001 and the high-probability internal / lottery table 1002 are switched at an arbitrary time.

  Replay A1016 (the same is true for replay 516 in FIG. 5) is a replay in which the replay symbols are aligned on the active line, and the next game can be replayed. On the other hand, the replay B1017 is a role controlled so that the symbols are not aligned by the reel control unit 106, and is not paid out and cannot be replayed in the next game. The replay B 1017 and the loser 517 in the normal table 501 have substantially the same reel control, and the player replays the loser 517 in the normal table 501 and the normal internal / lottery table 1001 or the high-probability internal / lottery table 1002. B1017 cannot be distinguished.

  When the BB or RB flag is once established and then a small combination or replay is established, the reel control is controlled so that the small combination or replay is preferentially aligned with the active line. That is, when the replay time is entered, the replay B 1017 is a kind of replay “unmatched replay”, so even if the BB or RB flag is established, the replay “unmatched replay” is given priority in reel control. In addition, in the replay time, the replay winning area is set wider than that in the normal game lottery table 121. Therefore, during the replay time, the small role or replay is established in most games while the special role flag is kept ON in the flag information storage unit 105, and the flag of lose 1018 is established. Or, unless the replay time ends (including winning in the stock cancellation lottery by a specific role described later), it is not possible to shift to the special game.

FIG. 11 is a diagram showing an example of the release table 123 used in the present embodiment.
The cancellation table 123 includes the tables shown in FIGS. 11A to 11D, and when a specific combination flag that is a part of the combination selected by the combination lottery unit 103 is established, the cancellation table 123 illustrated in FIGS. Using the table of (d), a lottery is performed as to whether or not to release the BB or RB stocked in the special part winning possible number storage unit 111.

  FIG. 11A shows a cherry A release table 1101. When the flag is established, one stocked BB or RB is released with a probability of 50%. FIG. 11B is a cherry B release table 1102, which releases one BB or RB stocked with a probability of 15% when the flag is established. FIG. 11C shows a watermelon release table 1103. When the flag is established, one stocked BB or RB is released with a probability of 25%. FIG. 11D shows a loss cancellation table 1104. When the flag is established, one stocked BB or RB is released with a probability of 100%.

  In addition, when both BB and RB are stocked in the special part winning possible number storage unit 111, whether to release BB or RB is determined in the order in which the special part winning possible number storage unit 111 is stocked. Alternatively, a lottery may be performed for whether to release BB or RB.

FIGS. 12A and 12B are flowcharts showing the control by the main control board 50 used in the present embodiment.
In FIG. 12A, when the player inserts a medal or presses the bet switch 43 (step S1201), the control unit 101 determines whether or not the player is in a three-sheet state (step S1202). . As a result of this determination, if it is not three, the process returns to step S1201 and further inserts medals or presses the bet switch. If the result of determination in step S1202 is that there are three sheets, the start switch 41 is operated. The control unit 101 detects that the start switch 41 has been turned on (step S1203), and checks whether either BB or RB is stocked in the special part winning possible number storage unit 111 (step S1203). S1204). If there is no stock in both BB and RB as a result of this confirmation (when the number of possible special winnings stored in the special winning winning number storage unit 111 is “0”), the winning lottery unit 103 determines that the lottery table during the normal game The lottery of the combination is performed at 121 (step S1205). If at least one special combination is stocked as a result of the confirmation in step S1204, the combination lottery unit 103 draws a combination in the internal lottery table 122 (step S1206).

  In addition, when a lottery of a role is performed in the normal game lottery table 121, there is no possibility of shifting to a special game, and when a BB or RB is won, a special winning prize is awarded via the special winning prize adding unit 110. The number of possible special winnings is incremented by one in the possible number storage unit 111, and then the replay time is entered, and the special part winning possible number storage unit 111 has no stock (the number of possible special winnings is “0”). Until then, the lottery of the combination will be performed in the internal lottery table 122.

  12-2 will be described. When the lottery of the winning combination is performed in the internal lottery table 122 in step S1206 of FIG. 12-1, the winning lottery unit 103 acquires a random number, and the acquired random number and the internal intermediate lottery A lottery process for a role is performed in the light of the table 122. As a result of the lottery, if any combination is won, the flag of the combination is turned on in the flag information storage unit 105.

  Then, the lottery unit 103 determines whether or not the above-mentioned specific combination is won (step S1207). If the specific winning combination is won as a result of the determination (step S1207 / YES), the cancellation lottery unit 112 performs lottery for stock cancellation based on the selected specific winning combination from the special combination winning possible number storage unit 111 (step S1207 / YES). S1208). Then, the lottery result of the combination in the internal lottery table 122 and the lottery result of the release are transmitted to the sub-control board 50 via the I / F circuit 54 (step S1209). If the specific combination is not won (step S1207 / NO), the lottery result of the combination in the internal lottery table 122 is transmitted to the sub-control board 50 via the I / F circuit 54 (step S1209).

  On the other hand, when the lottery of the combination is performed in the normal game lottery table 121 in step S1205 of FIG. 12A, the combination lottery unit 103 acquires a random number, and compares the acquired random number with the normal game lottery table 121. To perform a lottery process. As a result of the lottery, if any combination is won, the flag of the combination is turned on in the flag information storage unit 105. Then, the lottery result is transmitted to the sub-control board 50 via the I / F circuit 54 (step S1209).

  Next, the reel control unit 106 determines whether any one of the stop switch groups 42 has been operated (step S1210). If any one of the stop switches is operated (step S1210 / YES), reel control is performed so that the winning combination can be won, and rotation of the reel corresponding to the operated stop switch is stopped (step S1210 / YES). S1211).

  Subsequently, the reel control unit 106 determines whether all the stop switches are operated and all the reels are stopped (step S1212). When all the reels have not stopped yet (step S1212 / NO), the processing from the detection processing of presence / absence of the stop switch operation in step S1210 is repeated.

  When all the reels stop (step S1212 / YES), the winning determination unit 107 determines the presence or absence of winning based on the combination of symbols arranged on the activated effective line (step S1213). As a result, if there is any winning (step S1213 / YES), winning processing corresponding to the winning combination is executed (step S1214).

  If there is no winning (step S1213 / NO), the part lottery unit 103 determines whether or not the special part is won in the lottery of the part in the normal game lottery table 121 or the internal medium lottery table 122. (Step S1215). As a result of the determination, if the special role is won (step S1215 / YES), it is determined whether BB or RB has been won (step S1216). If BB is won, the process proceeds to step S1217. The number-of-wins-addable number adding unit 110 adds “1” to the number of times that the BB special role can be won. If the RB is won, the process proceeds to step S1218, and “1” is added to the number of RB special combination winnings possible.

  If the special combination is not won (step S1215 / NO), the medals are not paid out and the process ends.

  Also, in the release lottery in step S1208, if the release is won, it is promised that the state can be shifted to a special game after several game digests (preferably about 1 to 32 games are desirable). When this state is reached, the replay time ends, and the storage state of the flag in the winning flag information storage unit 105 is carried over until the special symbols corresponding to the special combination are arranged on the activated line.

  In addition, when the flag for a specific role is established and the lottery is won, the reel control is performed so that the special symbol corresponding to the special role is aligned on the activated line in the game won for the release lottery. You may go. For example, when a lost flag is established, reel control is performed so that special symbols of BB and RB are aligned on the activated effective line in the game, or when cherry flag is established, cherry and BB Reel control that can be arranged at the same time as a combined role with a special symbol of RB or RB may be performed.

  When the special symbols corresponding to the special combination are arranged on the activated effective line, the special game control unit 108 performs a transition process for executing the special game from the next game until the predetermined end condition is satisfied. During the special role game, the special game control unit 108 provides the reel control unit 106 with a special game so as to provide the player with a game state corresponding to the big bonus (BB) game or the regular bonus (RB) game that is the special role. The reel control inside is performed, or the sub control board 60 is made to produce special games.

  On the other hand, when the special symbols corresponding to the special role are arranged on the activated effective line, the special role winning possible number subtraction unit 113 calculates the special role winning possible number stored in the special role winning possible number storage unit 111. Subtract "1". That is, when it is determined by the winning determination unit 107 that the special role BB has won, “1” is subtracted from the number of BB special roles that can be won, and the winning determination unit 107 determines that the special role RB has won. If it is, “1” is subtracted from the number of RB special role winnings possible.

  Then, when the specified number of games of the big bonus (BB) game or the regular bonus (RB) game is finished, a process of shifting to the normal game or the replay time is performed.

Next, the switching process procedure of the lottery table 102 by the control unit 101 of the main control board 50 in the present embodiment will be described with reference to the flowchart of FIG.
In FIG. 8, the control unit 101 reads a set time at which the next table is switched from the switching time storage unit 104 (step S801). Next, the current time is read from the time counting unit 72 (step S802), and it is determined whether or not the set time read from the switching time storage unit 104 has been reached (step S803). If the result of this determination is that it has not been reached (step S803 / NO), the processing returns to step S802. If it is recognized that the destination has been reached (step S803 / YES), the lottery table 102 is switched (step S804).

  That is, the normal table 501 shown in FIG. 5 is switched to the high probability table 502, and the normal internal / medium lottery table 1001 shown in FIG. Or, as a reverse pattern, the high probability table 502 is switched to the normal table 501, and the high probability internal / medium lottery table 1002 is switched to the normal internal / medium lottery table 1001. When this switching is completed, the same processing is repeated.

  Further, as described above, since there is no transition to a special game during a normal game (no stock), switching between the normal table 501 and the high probability table 502 is not necessarily required, and a normal internal lottery is performed. Only switching between the table 1001 and the high-probability internal lottery table 1002 may be performed.

  As described above, in the present embodiment, since the lottery table 102 varies depending on time, it may be easy to win a specific combination suddenly. This may increase the chances of a stock cancellation lottery depending on the time, and a greater sense of tension even for players who are playing on a platform that seems to have a low number of bonus winnings in the past. Can be given.

  Also, in the present embodiment, the lottery table 102 has been described using two stages. However, for example, switching may be performed using the lottery table 102 having three or more stages such as low probability, normal, and high probability. In this case, the lottery table 102 may be switched in a regular order, or the lottery table 102 may be switched in an irregular order.

  Furthermore, in the present embodiment, an example in which the winning of all the specific roles performing the release lottery has a high probability has been described, but it is not always necessary to win the winning of all the specific roles performing the canceling lottery, for example, Alternatively, only some watermelons 1014 may have a high probability, and only some of the specific roles may have a high probability.

(Third embodiment)
In the first and second embodiments, the procedure for switching the winning lottery table 102 has been described. In this embodiment, the procedure for switching the release table 123 will be described. In the first and second embodiments, the control unit 101 reads the time recorded in the switching time storage unit 104 in order to perform a collation process with the time measured, but in the present embodiment, Similarly, the release lottery unit 112 reads the time recorded in the switching time storage unit 104.

  The appearance and hardware configuration of the slot machine are the same as the configurations shown in FIGS. 1 and 2 in the first embodiment, and thus the description thereof is omitted. The functional configuration of the sub control board is also the same as the configuration shown in FIG. 4 in the first embodiment, and a description thereof will be omitted. Furthermore, the configuration of the functions is the same as in the second embodiment except for the lottery table 102 and the release lottery unit 112, and thus the description thereof is omitted.

  In the present embodiment, the normal game lottery table 121 uses the normal table 501 in FIG. 5, and the internal medium lottery table 122 uses only the normal internal medium lottery table 1001 in FIG. Since the lottery table 102 is not switched by time, it is only a normal table.

FIG. 13 is a diagram illustrating an example of the release table 123 used in the present embodiment.
The release table 123 is composed of the tables shown in FIGS. 13A to 13H. FIGS. 13A, 13B, 13C, and 13D are respectively normal tables, and the normal cherry A release is performed. A table 1301, a normal cherry B release table 1302, a normal watermelon release table 1303, and a normal lose release table 1304 are shown. On the other hand, FIGS. 13 (e), (f), (g), and (h) are high probability cherry A release table 1305, high probability cherry B release table 1306, and high probability watermelon release table 1307, respectively, as high probability tables. The high probability loss cancellation table 1308 is shown. It switches between these normal tables and high probability tables.

  Both the normal loss cancellation table 1304 and the high probability loss cancellation table 1308 have a cancellation rate of 100%. During the replay time, the special role flag in the flag information storage unit 105 is always ON. Therefore, it is always canceled regardless of the state.

  In the present embodiment, the same processing procedure in the main control board 50 as in FIGS. 12-1 and 12-2 is performed, and the release lottery unit 112 performs the switching processing procedure shown in FIG. The normal cherry A release table 1301, the normal cherry B release table 1302, the normal watermelon release table 1303, and the normal loss release release table 1304 are divided into a high probability cherry A release table 1305, a high probability cherry B release table 1306, and a high probability watermelon release table 1307, respectively. Switching to the high probability loss cancellation table 1308 or switching in the opposite direction is also performed.

  As described above, in the present embodiment, since the release table 123 differs depending on time, there is a possibility that if a specific combination is won, the probability of releasing stock may be high, so that the setting with a low number of past bonus wins seems to be low. Even a player who is playing on a base can be given more tension when winning a specific role.

  Also, in the present embodiment, the release table 123 has been described using two stages. However, for example, switching may be performed using the release table 123 having three or more stages such as low probability, normal, and high probability. In this case, the release table 123 may be switched in a regular order, or the release table 123 may be switched in an irregular order.

  Furthermore, in the present embodiment, an example has been described in which the probability of release of the cherry A 1012, cherry B 1013, and watermelon 1014 is increased. However, the release probability is increased only when, for example, the cherry A 1012 is won. The cancellation probability may be increased only when the specific combination is won.

(Fourth embodiment)
Also, the second embodiment and the third embodiment can be performed simultaneously. In the present embodiment, when the control unit 101 and the release lottery unit 112 simultaneously read the current time from the time counter 72 and reach the set time read from the switching time storage unit 104, the lottery table 102 and the release table 123 and / or any one of them can be switched.

  Regarding the setting of the switching time, three types of switching time of the lottery table 102, switching time of the release table 123, and switching time of both the lottery table 102 and the releasing table 123 are selected using the time setting switch 84 shown in FIG. It becomes possible by setting. Of course, the switching time may be set manually, or the switching time may be set at random.

FIG. 14 is a diagram showing the expected degree of transition to a special game in the present embodiment.
As shown in FIG. 14, there are four types of lottery states for transition to special games according to the above settings. The state with the highest expectation is the state 1401 where both the lottery table 102 and the release table 123 have a high probability, and the state with the lowest expectation is the normal state 1404 for both the lottery table 102 and the release table 123. In addition, there are a state 1402 in which the lottery table 102 has a high probability and the release table 123 is normal, and a state 1403 in which the lottery table 102 is normal and the release table 123 has a high probability.

  In addition, as shown in the second embodiment, the normal game lottery table 121 may be switched at the same time. In that case, there are two types of lottery states during the normal game, and during the replay time, there are four types of lottery states as described above.

  As described above, in the present embodiment, the lottery table 102 and the release table 123 differ depending on time, so that the winning probability of the specific combination increases or the probability of releasing the stock increases when the specific combination is won. In some cases, players who are playing on a table that seems to have a low number of bonus winnings in the past will be given more tension because of the more complicated state transitions. Can do.

  In the present embodiment, the lottery table 102 and the release table 123 are described in two stages. However, for example, the lottery table 102 may be switched using the P stage and the release table 123 may be switched using the Q stage ( P, Q> 1). As a result, there are (P × Q) types of states, and more complicated state transitions can be performed. Each table in the lottery table 102 or the cancellation table 123 may change regularly or irregularly.

(Other embodiments)
In the first to fourth embodiments, when the lottery table 102 includes a combination that does not align with the active line 22 unless the pressing order of the stop switch 42 matches, the effect display device 40 is stopped. The present invention can also be applied to a slot machine having an assist time (AT) function for notifying the player of the pressing order of the switch 42.

  The first to fourth embodiments can be realized by a computer executing a program. The means for supplying the program to the computer may be a computer-readable recording medium such as a CD-ROM recording the program or a transmission medium such as the Internet for transmitting the program. The embodiment of the present invention has been described in detail with reference to the drawings.
