Description

  The present invention relates to a gaming machine in which a single game is executed based on a player's operation on condition that a prescribed number of gaming media are inserted.

  Conventionally, in one game executed based on the player's operation (referred to as “winning role determination game”), a game (“random number extraction game”) executed before the predetermined number of games of the winning role determination game. There is known a gaming machine such as a slot machine that determines a winning combination based on a random number value extracted in a random number value and a lottery table in which a range of random number values is preset (for example, Patent Document 1, 2).

  Further, in this gaming machine, an effect is determined based on a random number value for determining a winning combination, and an effect based on the random value extracted in the random number extraction game is executed in games after the random number extraction game. . In this way, after the random number extraction game, an effect corresponding to the winning combination determined in the subsequent winning combination determining game is executed for the player. Therefore, if an effect corresponding to the winning combination is executed after the random number extraction game, the player can have a sense of expectation that the winning combination may be won in the winning combination determination game. Can be increased.

Japanese Unexamined Patent Publication No. 2006-230665 (paragraphs [0111] to [0164], FIGS. 6 to 8, 10, 11, 15, abstracts, etc.) Japanese Unexamined Patent Publication No. 2006-230666 (paragraphs [0086] to [0126], FIGS. 5 to 7, 9, 10, abstracts, etc.)

  By the way, in a general gaming machine, a player needs to input a prescribed number of gaming media into the gaming machine in order to execute one game. Therefore, in order for the inserted game media not to be wasted, it is desirable that a lottery process for extracting a random value and determining a winning combination based on the extracted random value is executed for each game. However, in the conventional gaming machine described above, the random number value extracted in the random number extraction game is used in a winning combination determination game which is a later game, and the winning combination is determined. That is, even if a random number value that can obtain a profit can be extracted, the profit cannot be enjoyed until after a predetermined number of games.

  Therefore, until the winning combination determination game is executed, the player can execute a highly reliable performance related to the winning combination by using the random value extracted in the random number extraction game, while the random number is extracted. There is a possibility that the player who executed the extraction game will finish the game before the winning combination determination game is executed after the predetermined number of games in which the winning combination is determined based on the random number value extracted in the random number extraction game. In this case, depending on the random number value extracted in the random number extraction game, the player who executed the random number extraction game may suffer a disadvantage.

  In addition, since the winning combination determination game, that is, the lottery process in the current game is performed based on the random value extracted in the random number extraction game executed before the predetermined number of games, the winning combination determined in the current game is determined. Are substantially drawn in a random number extraction game executed before a predetermined number of games. Therefore, in each game, the player executes the game in a so-called race state despite the fact that the lottery result has already been decided, and improvement is required from the viewpoint of the fairness of the game. It was.

  The present invention has been made in view of the above problems, and an object thereof is to provide a gaming machine capable of executing a highly reliable production related to a specific lottery result without causing a disadvantage to the player. .

  In order to achieve the above object, a gaming machine according to the present invention includes a plurality of gaming machines in which a single game is executed based on a player's operation on condition that a specified number of gaming media are inserted. Display means for variably displaying the symbols of the type, lottery means for performing lottery including determination as to whether or not a specific lottery result having a winning probability P has been won, and the display in the game based on the lottery result by the lottery means Display control means for controlling the display result of the symbol by means, and effect control means for effecting the player, wherein the lottery means is the winning probability P = preliminary winning probability Pa (1> Pa> P) × Preliminary lottery means for determining whether or not the preliminary lottery with the preliminary winning probability Pa was won for each game when the final winning probability Pb (1> Pb> P) was satisfied, and the preliminary lottery was performed Predetermined game times In a game executed later, a final determination lottery for determining whether or not a final determination lottery of the final determination probability Pb has been won, a result of the final determination lottery, and the predetermined number of games of the game in which the final determination lottery has been performed If the result of the preliminary lottery in the previously executed game is a win, the lottery determination unit determines that the specific lottery result has been won, and the effect control unit includes the preliminary lottery unit. An effect according to the result of the preliminary lottery is performed (claim 1).

  Further, the preliminary lottery means determines whether or not the preliminary lottery with the preliminary winning probability Pa has been won, and determines whether or not another lottery result different from the specific lottery result has been won. If the result of the general lottery by the preliminary lottery means is a win, the lottery determination unit may determine that the other lottery result has been won (claim 2).

  The lottery means further includes display control storage means for storing a result of the preliminary lottery of the preliminary lottery means in at least the most recent predetermined number of games, and the lottery determination means In addition, among the preliminary lottery results stored in the display control storage means, it is determined whether or not the specific lottery result has been won based on the preliminary lottery results before the predetermined number of games. And determining whether or not the other lottery result is won based on the result of the general lottery in the current game, and the display control means is based on the determination result by the lottery determination means for each game. The display means may be controlled (claim 3).

  The lottery means further includes display control storage means for storing a result of the preliminary lottery of the preliminary lottery means in at least the most recent predetermined number of games, and the lottery determination means In addition, among the preliminary lottery results stored in the display control storage means, it is determined whether or not the specific lottery result has been won based on the preliminary lottery results before the predetermined number of games. And determining whether or not the other lottery result is won based on the result of the general lottery before the predetermined number of games, and the display control unit displays the determination result by the lottery determination unit for each game. Based on this, it is preferable to control the display means (claim 4).

  The production control means further includes production control storage means for storing the preliminary lottery result of the preliminary lottery means and the result of the general lottery, and the preliminary lottery stored in the production control storage means And an effect based on the result of the general lottery may be performed.

  The lottery means further comprises a random number generating means for generating a random number for lottery of (a + b) bits, and a random number extracting means for extracting a random number generated by the random number generating means, and the preliminary lottery means includes: It is determined whether or not the winning is performed using a value of a bit of the random number extracted by the random number extracting unit, and the final lottery unit calculates a value of b bit of the random number extracted by the random number extracting unit. It is good to determine whether or not it has been won using (Claim 6).

  According to the invention of claim 1, the determination by the lottery means whether or not a specific lottery result having the winning probability P has been won is the winning probability P = preliminary winning probability Pa (1> Pa> P) × confirmed winning probability When Pb (1> Pb> P) is satisfied, for each game, whether or not the preliminary lottery with the preliminary win probability Pa is won is determined by the preliminary lottery means, and the predetermined game of the game in which the preliminary lottery is performed In the game executed after the number of times, the determination of whether or not the final lottery with the final determination probability Pb has been won is performed by the final determination lottery means, so that the final lottery result and the predetermined game of the game in which the final determination lottery has been performed If the result of the preliminary lottery in the game executed before the number of times is a win, the lottery determination means determines that a specific lottery result having a win probability P has been won.

  Therefore, the probability of winning the final lottery with the final winning probability Pb is larger than the probability of winning the specific lottery result with the winning probability P, and the game executed before the predetermined number of games of the game in which the final lottery was performed. Whether or not there is a possibility of winning a specific lottery result is determined according to the result of the preliminary lottery. Therefore, the production control means uses the result of the preliminary lottery determination by the preliminary lottery means with the winning probability Pa, thereby giving the player a highly reliable performance regarding the probability of winning the specific lottery result with the winning probability P. Can be executed. Also, whether or not a specific lottery result has been won is determined by a final lottery by a final lottery means in a game executed after a predetermined number of games of the game in which a preliminary lottery has been performed. Therefore, even if the player finishes the game after the game in which the preliminary lottery is performed and before the final lottery is executed, the determination as to whether or not the specific lottery result has been won is not fixed, and the game Will not be disadvantaged. In other words, the effect control means can execute an effect using a result of the preliminary lottery by the preliminary lottery means, and can execute a highly reliable effect related to a specific lottery result without detriment to the player. .

  Further, whether or not a specific lottery result has been won is determined by the lottery determination means based on the final lottery result in the current game. It is possible to execute a highly reliable performance related to a specific lottery result while ensuring the fairness of the game without executing the game in the final race state.

  According to the invention of claim 2, the preliminary lottery means determines whether or not the preliminary lottery with the preliminary winning probability Pa has been won, and whether or not another lottery result different from the specific lottery result has been won. Since the general lottery for determining is performed, the processing efficiency can be improved.

  According to the invention of claim 3, the preliminary lottery result of the preliminary lottery means in at least the most recent predetermined number of games is stored in the display control storage means of the lottery means, and the lottery determination means is Among the preliminary lottery results stored in the display control storage means, a determination is made as to whether or not a specific lottery result has been won based on the preliminary lottery results before a predetermined number of games, and in general in the current game By determining whether or not other lottery results have been won based on the lottery result, the display control means can determine the determination result by the lottery determination means based on the preliminary lottery result and the general lottery result for each game. Since the control of the display means can be made different based on this, the player's interest can be enhanced.

  According to the invention of claim 4, the preliminary lottery result of the preliminary lottery means in at least the most recent predetermined number of games is stored in the display control storage means of the lottery means, and the lottery determination means is Then, among the preliminary lottery results stored in the display control storage means, it is determined whether or not a specific lottery result has been won based on the preliminary lottery result before the predetermined number of games, and By determining whether or not other lottery results have been won based on the result of the general lottery, the display control means determines the result of the lottery determination based on the result of the preliminary lottery and the result of the general lottery for each game. Since the control of the display means can be made different based on the game, the player's interest can be enhanced.

  According to the invention of claim 5, the result of the preliminary lottery by the preliminary lottery means and the result of the general lottery are stored in the effect control storage means of the effect control means, so that the effect control means is stored in the effect control storage means. This is practical because an effect based on the stored preliminary lottery result and general lottery result can be performed.

  According to the invention of claim 6, when the random number extraction means extracts a random number for (a + b) bits generated by the random number generation means, and once the random number is extracted by the random number extraction means, the preliminary lottery means Can determine whether or not the winning is made using the value represented by the a bits of the random number extracted by the random number extracting means, and the final lottery means determines the b of the random number extracted by the random number extracting means. Since it is possible to determine whether or not the winning is performed using the value represented by the bit, it is efficient.

Further, the sub CPU 71 receives various data relating to the gaming machine transmitted from the main CPU 61 (the gaming state of the slot machine 1, whether a medal is inserted, whether one of a plurality of roles is won by lottery means 110, Based on data relating to whether or not the game has been paid out, the program stored in the memory 75 is executed to provide an effect control means 105 for controlling effects related to the game for the player. Next, the main control board 63 will be described in detail.

(Main control board)
As shown in FIG. 4, the main control board 63 has various functions realized by executing programs stored in the ROM 67 and various functions realized by hardware.

(1) Normal game control means 100
The normal game control means 100 controls a normal game that is a general game. Hereinafter, the game in the normal game state will be described. In this embodiment, in the normal gaming state, a game is played with a maximum of three medals, and the bet number counter 651 stores up to three inserted medals.

  When the insertion sensor 53, the bet switch 15 or the maximum bet switch 17 detects the insertion of medals, the number of winning lines corresponding to the number of inserted coins becomes valid. For example, if the maximum number of winning lines to be valid is 5 and the number of inserted medals is 1, the central horizontal winning line (center line) is valid and the number of inserted medals is 2 In this case, three winning lines are effective by adding the upper horizontal line and the lower horizontal line to the center line, and when the number of inserted medals is three, the three winning lines are effective. Five lines are effective, including a line that is inclined to the right and a line that is inclined to the right. When it is detected that the start switch 19 has been operated on condition that a predetermined number of medals have been inserted, the lottery means 110 performs a lottery to determine whether one of a plurality of preset roles has been won or lost. In addition, all rotations of the left, middle and right reels 13L, 13M, and 13R are started, and the symbols of the reels 13L, 13M, and 13R displayed on the reel window 11 are adjusted to the rotation angles of the reels 13L, 13M, and 13R. Start to determine.

  Thereafter, the operation of all the stop switches 21L, 21M, and 21R becomes effective. When it is detected that the left stop switch 21L is operated, the left reel is stopped, and when it is detected that the middle stop switch 21M is operated, the middle reel 13M is stopped, and when it is detected that the right stop switch 21R is operated, the right reel 13R is stopped. Thus, the operation of the stop switches 21L, 21M, and 21R stops the rotation of the left, middle, and right reels 13L, 13M, and 13R corresponding to the stop switches 21L, 21M, and 21R.

  When all three left / middle / right stop switches 21L, 21M, and 21R have been operated, the rotation of all three left / middle / right reels 13L, 13M, and 13R is stopped. At this time, when a predetermined symbol stops at a predetermined position on the activated pay line, a winning is achieved. Then, the number of medals corresponding to the winning mode is credited or paid out from the payout exit 39. In addition, instead of paying out medals or along with paying out medals, a predetermined profit may be given to the player.

  As the winning combination, as the “specific lottery result” of the present invention, the first special combination (big bonus (BB)) and the second special combination (regular bonus (RB)) are set in advance. As the “other lottery results”, the first small combination, the second small combination, the third small combination, and the re-playing combination are set in advance. The lottery result of the lottery means 110 includes the first special role winning (BB winning), the second special role winning (RB winning), the first small role winning, the second small role winning, and the third small winning number. There are role winning, replay winning (Replay winning), and loss.

  In addition, the prizes include the transition to the first special game prize (BB prize) related to the transition to the first special game (Big Bonus (BB) game) and the second special game (Regular Bonus (RB) game). The second special combination winning (RB winning), the first small winning combination related to paying out a predetermined number (for example, 10 medals), and the second small winning combination related to paying out a predetermined number (for example, 6) medals. And a third small winning combination related to paying out a predetermined number (for example, one) of medals and a replay winning combination (Replay winning) related to execution of replay (Replay).

  Note that the first special game (BB game) and the second special game (RB game) are games that are easy to receive game medals, such as setting the winning probability of a small role higher than in the normal game state. . Accordingly, the first special game and the second special game are games that are more advantageous to the player than the normal game, and are games in which the player can acquire more medals.

  In this embodiment, each of the first special game and the second special game ends each special game (bonus game) when the number of medals paid out in each special game exceeds a predetermined upper limit number different from each other. Thus, it is provided to shift to a normal game. For example, the upper limit number in the first special game is set as the first payout upper limit number (300), and the upper limit number in the second special game is set as the second payout upper limit number (100). In this embodiment, the upper limit number of payouts in each special game is set to a common value for all set values.

  Then, for example, if three “Red 7” symbols are arranged on an effective winning line, the first special role winning is achieved, the BB game (first special game) is executed, and the “BAR” symbol is valid. When three pieces are arranged on the winning line, a second special role winning is achieved and an RB game (second special game) is executed. That is, the combination of symbols for the first special role winning (the winning mode of the first special role) is “red 7-red 7-red 7”, and the combination of symbols for the second special winning combination (second special role) Is a “BAR-BAR-BAR”.

  In this embodiment, there is no medal payout by the first special role winning and the second special role winning (the number of prescribed payouts of the first special role and the second special role is 0), and each winning mode related to each special role is The game is configured to shift to each bonus game after the established game, but a predetermined number (for example, 10) is set as the prescribed payout number of each special combination, and after the medal is paid out, the game proceeds to each bonus game. It may be.

  Further, for example, when three “bell” symbols are arranged on an effective winning line, it becomes the first small role winning and 10 medals are paid out. Further, for example, when three “orange” symbols are arranged on an effective winning line, a second small role winning is achieved and six medals are paid out. Also, for example, when the rotation of the left reel 13L is stopped, if the “cherry” symbol stops on an effective winning line, the third small size is displayed regardless of the symbols displayed on the middle and right reels 13M and 13R. A winning prize is awarded, and one (when stopped in the middle) or two (when stopped in the upper or lower) medals are paid out. Further, for example, when three “Replay” symbols are arranged on an effective winning line, a Replay winning is achieved, and a game can be played again under the same conditions as the previous game without inserting a new medal.

  When the lottery result is the first special combination winning, the stop control of the symbols based on the first special combination winning is performed. At this time, the symbol arrangement (“red 7-red 7-red” of the first special combination winning combination is performed. If “7”) is not allocated, the first special combination winning is carried over until the symbol arrangement of the winning mode of the first special combination is allocated. The second special role winning is the same as the first special role winning. In addition, the first small role winning is not carried over to the next game unless the drawing result of the first small role winning is assigned to the winning pattern of the first small role. Yes. The same applies to the second small role winning, the third small role winning and the Replay winning.

  In addition, the aspect of the lottery by the lottery means 110 will be described in detail later.

(2) Special game control means 101
The special game control means 101 controls a special game (bonus game) that is a game advantageous to the player over the normal game. In this embodiment, the special game control means 101 is configured to play a big bonus (BB) game and a regular bonus (RB) game as special games (bonus games). Hereinafter, the BB game will be mainly described.

  When the lottery result of the lottery means 110 is the first special combination winning, the symbol stop control based on the first special combination winning is performed. At this time, if three “red 7” symbols are arranged on the effective winning line, the first special winning prize is obtained. And when it becomes the 1st special combination prize, it shifts to the 1st special game (BB game). In this embodiment, the priority order in the stop control of the symbols of the reels 13L, 13M, and 13R is set between the special role winning, the re-game winning, and the small role winning. The symbol stop control is preferentially performed in the order of small role winning and special role winning. For example, when a re-game combination is won in a state where the first special combination selection is carried over, stop control is performed so that the symbol corresponding to the re-game combination (Replay design) is given priority and stopped on the active line.

  The BB game (first special game) is configured by repeatedly executing a specific game composed of a plurality of games. Specifically, when starting the BB game, first, the first specific game (multiple games) is executed, and when the specific game end condition is satisfied during the execution of the specific game, the specific game is ended. Let Following the end of the first specific game, the second specific game (multiple games) is executed until the specific game end condition is satisfied. Similarly, the third and subsequent specific games are executed until the specific game end condition is satisfied. In this way, the BB game (first special game) is configured by repeatedly executing the specific game.

  However, in this embodiment, when the specific game is repeatedly executed in the BB game, when the payout number of medals paid out during the bonus game exceeds the first payout upper limit number (300), Regardless of the specific game end condition, the BB game is ended (consent with the end of the specific game).

  The special game control means 101 in this embodiment first determines whether or not the first payout upper limit number is exceeded before starting each specific game. If the first payout upper limit number is exceeded, the BB game is determined. If (the start of the specific game) is finished and the first payout upper limit number is not exceeded, it is determined whether or not the specific game end condition is satisfied, and the specific game is executed based on the determination result.

  In addition, as the specific game end condition, two end conditions are set, that is, whether the number of executions of the specific game reaches 12 times and whether the number of winnings in the specific game reaches 8 times. If at least one of the two end conditions is satisfied, the specific game is ended.

  Unlike a normal game, a specific game can insert a maximum of one medal, and a game is played with one effective pay line set. Then, the lottery means 110 performs a lottery every time a winning combination is won or lost. Whether or not a predetermined symbol predetermined corresponding to the winning combination is stopped at a predetermined position when rotation of all three left, middle and right reels 13L, 13M and 13R is stopped Thus, whether or not a prize is won is determined by the winning determination means 150.

  Moreover, when the lottery result of the lottery means 110 is the second special combination winning, the symbol stop control based on the second special combination winning is performed. At this time, if three “BAR” symbols are arranged on an effective winning line, a second special prize winning is obtained. Then, when the second special combination winning is made, the process shifts to the second special game (RB game), and the specific game is repeatedly executed in the same manner as the BB game described above, and the number of medals to be paid out during the RB game. The RB game is ended when the second payout upper limit number (100) is reached.

  Further, in this embodiment, in the BB game and the RB game, the winning probability at the time of the lottery means 110 (in the case of the normal game) from the normal game lottery table that defines the winning probability at the time of the lottery means 110 in the normal game. By switching to a special game lottery table that prescribes a higher probability), the winning probability of the small role is set to be higher than in the normal game. As a result, the first and second special games (bonus games) are games that are more advantageous to the player than the normal games.

(3) ROM67
The ROM 67 stores a plurality of lottery tables 671 in which different lottery probabilities are set, and a plurality of stop tables 672 for controlling stop of the reels 13L, 13M, and 13R.

  The lottery table 671 is for performing a lottery for winning or losing any one of a plurality of predetermined roles, and a plurality of random numbers generated by the random number generation unit 111 described below are used for a plurality of random numbers. Whether or not one of the winning combinations is won is determined in advance at a predetermined ratio (lottery probability).

  In addition, as the lottery table 671, a plurality of types of lottery tables having different expected values for increasing the number of medals in the lottery are provided. In this embodiment, the setting 1 from the lowest expected value to the setting 6 having the highest expected value is provided. Six types of lottery tables are provided. Each of these multiple types of lottery tables is further provided with a lottery table for normal games and special games (bonus games). In addition, for normal games, a lottery table is provided so that the expected payout value varies depending on the number of inserted medals (the number of bets).

  An example of the lottery table 671 will be described with reference to FIGS. FIG. 5 is an example of a normal game lottery table at a predetermined set value. In the normal game lottery table, the first special combination (BB) and the second special combination (RB), which are specific lottery results, are won. The preliminary winning probability Pa for each special role in the preliminary lot executed to determine whether or not, and the first to third small roles (bell, orange, cherry), which are other lottery results, A general winning probability for each winning combination in the general lottery executed to determine whether or not (Replay) has been won is set. FIG. 6 is an example of a final lottery table at a predetermined expected value. In the final lottery table, whether the first special combination (BB) and the second special combination (RB), which are specific lottery results, are won. A determined winning probability Pb for each special combination in the determined lottery executed to determine whether or not is set.

In this embodiment, the winning probability P of the first special combination (BB) is set to 273/65536, and the preliminary winning probability Pa and the confirmed winning probability Pb set for the first special combination are:
Winning probability P (273/65536) = Preliminary winning probability Pa (1092/65536) × Final winning probability (1/4)
It is set to satisfy. In addition, the winning probability P of the second special combination (RB) is set to 163/65536, and the preliminary winning probability Pa and the final winning probability Pb set for the second special combination are:
Winning probability P (163/65536) = Preliminary winning probability Pa (652/65536) × Final winning probability (1/4)
It is set to satisfy.

  The preliminary lottery and the final lottery executed by the lottery means 110 will be described in detail later.

(4) Setting control means 170
The setting control means 170 selects a lottery table 671 selected by the table selection means 120 described later by setting setting values (setting 1 to setting 6), and a plurality of lotteries stored in the ROM 67. Each setting value is associated with each table 671. The setting control means 170 determines the on / off state of the change process start switch 56 when the power is turned on, and starts a predetermined setting change process when the power is turned on with the change process start switch 56 being on.

  In this embodiment, the winning probabilities in the normal game lottery are set in a plurality of stages distinguished by a plurality of types of setting values (six types in this embodiment), and a lottery table 671 is provided for each of the plurality of stage setting values. (Normal game lottery table) is associated. When the setting change process is started, the manager of the pachinko hall where the slot machine 1 is installed can change the setting value.

  This procedure is performed as follows, for example. That is, the administrator opens the front panel 5, inserts a setting change key (not shown) into the key cylinder 51 of the operation box 49 and rotates the power switch 50, and turns the change processing start switch 56. turn on. In this state, the setting change process is started by turning on the power switch 50.

  Then, the winning probability setting value is cyclically switched from setting 1 to setting 6 for each operation of the setting change button 52 by the administrator. This set value is notified by displaying 1 to 6 by a 7 segment type set value display LED, for example. When the set value of the winning probability becomes a desired value by operating the setting change button 52 (the display value of the setting value display LED becomes a desired value), the set value is determined by operating the start switch 19. . When the setting change key inserted in the key cylinder 51 is rotated and the change process start switch 56 is turned off, the setting change process ends. Thereafter, when a medal is inserted from the medal slot 25, the game is started.

(5) Table selection means 120
The table selection means 120 is a type of game (normal game, BB, RB game, etc.) controlled by the normal game control means 100 and special game control means 101 on the main control board 63, and a set value set by the setting control means 170. One lottery table is selected as a selected lottery table from a plurality of lottery tables 671 based on (Setting 1 to Setting 6) and the number of medals inserted (the number of bets) inserted by the player. That is, for example, in a normal game, the table selection means 120, as a selection lottery table, according to the setting value (setting 1 to setting 6) of the winning probability, the number of medals inserted is one, two is three, The lottery table 671 (normal game lottery table) corresponding to each of the cases is selected.

(6) Lottery means 110
The lottery means 110 performs random lottery including determination whether or not a specific lottery result (first special role, second special role) having a winning probability P (273/65536, 163/65536) has been won. 4, random number generation means 111, random number extraction means 112, preliminary lottery means 113, fixed lottery means 114, and lottery determination means 115 are provided. The random number generator 111 generates a random number for lottery within a predetermined range. In this embodiment, the random number generator 111 is a random number having a value represented by (2 + 16) bits, that is,
0000 00XX / AAAAA AAAA / AAAAA AAAA
The random number for lottery of 3 bytes represented by is generated. Therefore, the random number generator 111 generates a random number in the range of 0 to 65535 represented by 16 bits (AAAAA AAAA / AAAAAAAAA), and a value of 0 to 3 represented by 2 bits (XX). Generate random numbers in the range The random number generation means 111 can be constituted by, for example, an oscillation circuit and a counter circuit that counts clock signals generated by the oscillation circuit (so-called hard random number).

  The random number generating means 111 can be constituted by means for generating random numbers by the average sampling method, or means for generating random numbers by adding prime numbers, for example. These means can be configured, for example, by causing the main CPU 61 to execute a predetermined program (so-called soft random number). Further, both hard random numbers and soft random numbers may be provided, and random numbers may be generated in a software manner based on the results.

  The random number extraction unit 112 extracts a random number generated by the random number generation unit 111, and extracts the random number generated by the random number generation unit 111 under a predetermined condition (for example, operation of the start switch 19 in this embodiment). Since the random number generation unit 111 is configured by a counter circuit or the like, the numerical value generated by the random number generation unit 111 is not strictly a random number. However, since the timing at which the start switch 19 is operated is considered to be random, the numerical value extracted by the random number extraction means 112 can be substantially handled as a random number.

  As shown in FIG. 5, the preliminary lottery means 113 uses, for each game, a value corresponding to 16 bits (AAAAAAAAA / AAAAAAAAA) of the random number extracted by the random number extraction means 112, as shown in FIG. It is determined whether or not the preliminary lottery (provisional BB, temporary RB) for the first special combination and the second special combination for which is set is won, and individual winning probabilities are set as shown in FIG. It is determined whether or not the general lottery for the first to third small combinations and the re-playing combination is won.

Specifically, the preliminary lottery means 113 sets the entire range of values represented by 16 bits (AAAAAAAAA / AAAAAAAAA) of random numbers generated by the random number generator means 111 in the normal game lottery table. Based on the winning range assigned to the winning role,
Temporary BB: 0-1091 (winning range: 1092),
Temporary RB: 1092-1743 (winning range: 652),
Bell: 1744-8296 (winning range: 6553),
Orange: 8297-9115 (winning range: 819),
Cherry: 9116-9770 (winning range: 655),
Replay: 9771-18750 (winning range: 8980),
Loss: 18751-65535 (applicable range: 46785),
Assign to each winning combination and divide. Then, the preliminary lottery means 113 uses a value of 16 bits (AAAA AAAA / AAAAAAAAA) of the random number extracted by the random number extraction means 112 to generate a random number of 16 bits (AAAA AAAA / AAAAA AAAA) generated by the random number generator 111. Whether or not the preliminary lottery (provisional BB, temporary RB) has been won or whether the general lottery has been won, depending on which range assigned to each winning combination belongs to the entire range of values represented by minutes (Whether it corresponds to the 1st small role (bell), 2nd small role (orange), 3rd small role (cherry), re-playing role (Replay)), it is judged whether it corresponds to a loser. .

The confirmed lottery means 114 uses a value corresponding to 2 bits (XX) of the random number extracted by the random number extraction means 112 in a game executed after 4 games (predetermined number of games) of the game in which the preliminary lottery is performed, As shown in FIG. 6, it is determined whether or not the final lottery for the first special combination and the second special combination for which the individual final selection probability Pb is set has been won. Specifically, the determined lottery means 114 has a value corresponding to 2 bits (XX) of the random number extracted by the random number extraction means 112.
“XX” = “00”
If so, it is determined that the final lottery for the first special combination (BB) or the second special combination (RB) has been won.

Note that the random number generation means 111 is a (2 + 2 + 16) bit random number, that is,
0000 YYXX / AAAAA AAAA / AAAAA AAAA
A random number for lottery of 3 bytes represented by In this case, the fixed lottery means 114 is based on the value of 2 bits (XX) of the random number extracted by the random number extraction means 112,
“XX” = “00”
If it is determined that the final lottery for the first special role (BB) is won, based on the value of 2 bits (YY) of the random number extracted by the random number extraction means 112,
“YY” = “00”
If so, it may be determined that the final lottery for the second special combination (RB) has been won.

  The lottery determination means 115 includes the result of the final lottery by the final lottery means 114 and the result of the preliminary lottery by the preliminary lottery means 113 in the game executed four times before the game in which the final lottery was performed (predetermined number of games). If it is a win, it is determined that the first special combination (BB) or the second special combination (RB), which is a specific lottery result, has been won. That is, for each game, the lottery determination means 115, among the preliminary lottery results by the preliminary lottery means 113 stored in the reel stop control lottery result storage means 653, results of the preliminary lottery before the predetermined number of games (this embodiment). If the result of the preliminary lottery in the previous four games) is a win for the temporary BB or the temporary RB, if the final lottery result by the final lottery means 114 in the current game is a win, the specific lottery result It is determined that a certain first special combination (BB) or second special combination (RB) is won.

  In addition, if the result of the general lottery of the preliminary lottery unit 113 in the current game is a win, the lottery determination unit 115 wins one of the other lottery results (first to third small roles, re-game player). Is determined. That is, in this embodiment, the lottery determination means indicates that, for each game, the result of the general lottery by the preliminary lottery means 113 in the current game stored in the reel stop control lottery result storage means 653 is the first to third small roles. When one of the re-game players is won, it is determined that any one of the first to third small roles or the re-game players, which are other lottery results, has been won.

  The result of the preliminary lottery by the preliminary lottery means 113 is stored in the reel stop control lottery result storage means 653 formed in the RAM 65. In this embodiment, the reel stop control lottery result storage means 653 is configured to store the result of preliminary lottery of the preliminary lottery means 113 in four games. Accordingly, when the reel stop control lottery result storage unit 653 stores the result of the preliminary lottery of the preliminary lottery unit 113 in the current game, the preliminary lottery in the game before the four games (game), that is, the game before the predetermined number of games. The preliminary lottery result by the means 113 is cleared and the preliminary lottery result by the latest (current game) preliminary lottery means 113 is stored. Thereby, after the preliminary lottery by the preliminary lottery means 113 is performed, the result of the oldest preliminary lottery stored in the reel stop control lottery result storage means 653 is the preliminary lottery by the preliminary lottery 113 in the game three games before. Result.

  In this embodiment, as will be described later with reference to FIG. 9, the final lottery (step S103) is executed by the final lottery 114 before the preliminary lottery (step S104) by the preliminary lotter 113 is executed. Therefore, when the final lottery is executed, the result of the oldest preliminary lottery stored in the reel stop control lottery result storage unit 653 is the preliminary lottery by the preliminary lottery 113 in the game 4 games (predetermined number of games) before. Result.

  The determination result of the lottery determination unit 115 based on the result of the general lottery by the preliminary lottery unit 113 is stored in the reel stop control lottery result storage unit 653 formed in the RAM 65. In this embodiment, the reel stop control lottery result storage unit 653 is configured to store the determination result of the lottery determination unit 115 based on the result of the general lottery in the current game. Therefore, when the reel stop control lottery result storage unit 653 stores the determination result of the lottery determination unit 115 based on the result of the general lottery in the current game, the lottery determination unit 115 based on the result of the general lottery in the previous game. And the determination result of whether or not the first small combination to the third small combination or re-game combination is won by the latest (current game) lottery determination means 115 is stored. Thus, after the general lottery by the preliminary lottery means 113 is performed, the reel stop control lottery result storage means 653 stores the first small role to the first small combination by the lottery determination means 115 based on the result of the general lottery in the current game. The determination result of whether or not the three small combination or replay combination is won is stored.

  The determination result of the lottery determination unit 115 based on the result of the final determination lottery by the final determination lottery unit 114 is stored in the reel stop control lottery result storage unit 653 formed in the RAM 65. In this embodiment, the reel stop control lottery result storage unit 653 is configured to store the determination result of the lottery determination unit 115 based on the final lottery result in the current game. Therefore, when the reel stop control lottery result storage unit 653 stores the determination result of the lottery determination unit 115 based on the final lottery result in the current game, the lottery determination unit 115 based on the final lottery result in the previous game. And the determination result of whether or not the first special combination or the second special combination is won by the latest (current game) lottery determination unit 115 is stored. Thus, after the final lottery is performed by the final lottery unit 114, the reel stop control lottery result storage unit 653 stores the first special combination or the first special combination by the lottery determination unit 115 based on the final lottery result in the current game. 2 A determination result as to whether or not a special combination is won is stored.

  The number of games for storing the result of the preliminary lottery by the preliminary lottery means 113 is not limited to four, but the number of games for storing the determination result of the lottery determination means 115 based on the results of the general lottery and the final lottery. Is not limited to once. In this embodiment, the temporary BB is won when the preliminary lottery for the first special role (BB) is won, and the temporary RB is won when the preliminary lottery for the second special role (RB) is won. It shall be elected.

(7) Detection means 130
The detection means 130 includes detection signals from the left / middle / right position sensors 55L, 55M, and 55R and the number of pulses supplied to the reel motors 14L, 14M, and 14R that drive the left / middle / right reels 13L, 13M, and 13R. Based on the above, the rotational positions of the left, middle and right reels 13L, 13M and 13R are detected. That is, the detection means 130 corresponds to a symbol located at a predetermined reference position (for example, the middle stage of the display window 11 in this embodiment) while the left / middle / right reels 13L, 13M, and 13R are rotating and stopped. Each frame number to be detected is detected.

(8) Stop control means 140
The stop control unit 140 (corresponding to the “display control unit” of the present invention) performs stop control of the reels 13L, 13M, and 13R using the stop table 672 based on the lottery result of the lottery unit 110, and the reels 13L and 13M. , 13R to control the display result of the symbol. That is, the stop control unit 140 performs stop control of the reels 13L, 13M, and 13R based on the determination result by the lottery determination unit 115 for each game.

  In the stop table 672, a plurality of tables are set corresponding to each lottery result of the lottery means 110. This stop table 672 is for determining the stop position of each of the reels 13L, 13M, 13R, and corresponds to the rotational position of the reels 13L, 13M, 13R when the stop switches 21L, 21M, 21R are operated. Thus, the number of sliding frames of the reels 13L, 13M, 13R is predetermined. The stop table 672 includes, for example, a stop table for all reels that collectively determines the number of sliding frames of all the reels 13L, 13M, and 13R. The stop table 672 is not limited to the all-reel stop table in which the number of sliding frames of all the reels 13L, 13M, and 13R is collectively determined. (Reel stop table) and a table (middle / right reel stop table) in which the number of sliding frames of the middle / right reels 13M, 13R is determined. Further, the stop table 672 is stopped, for example, when the left reel 13L is stopped first (first stop), when it is stopped second (second stop), and when it is stopped third (third stop). For example, the number of sliding frames (table data) may be different depending on the time, and the stop operation order of each reel 13L, 13M, 13R may be determined.

  Then, the stop control unit 140 first selects one stop table 672 from among the plurality of stop tables 672 based on the lottery result of the lottery unit 110. Next, the number of sliding frames of the reels 13L, 13M, 13R is determined from the selected one stop table 672 and the rotational positions of the reels 13L, 13M, 13R when the stop switches 21L, 21M, 21R are operated. To do.

  Here, if the number of sliding frames is determined to be 0, the rotation of the reels 13L, 13M, 13R is immediately stopped. That is, when the number of sliding frames is determined to be 0, the symbols displayed in the upper part of the display window 11 when the stop switches 21L, 21M, and 21R are operated are stopped and displayed in the upper part of the display window 11 as they are. . If the number of sliding frames is determined to be 1, the reels 13L, 13M, and 13R are rotated and stopped by one frame. That is, when the number of sliding symbols is determined as 1, the symbols displayed on the upper stage of the display window 11 when the stop switches 21L, 21M, and 21R are operated are 1 in the rotation direction of the reels 13L, 13M, and 13R. The frames are shifted and stopped and displayed in the middle of the display window 11.

  Moreover, the stop control means 140 of this embodiment, if the lottery result of the lottery means 110 is one of a plurality of winning combinations, the stop table 672 selected based on the lottery result and the stop switches 21L and 21M , 21R is determined from the rotational position of the reels 13L, 13M, 13R when the winning combination is won, and the number of sliding frames of the reels 13L, 13M, 13R is determined so that the reels 13L, 13M, 13R Perform stop control. Moreover, the stop control means 140 of this embodiment is, when the lottery result by the lottery means 110 is lost, when the stop table 672 selected based on the lottery result and the stop switches 21L, 21M, and 21R are operated. From the rotational positions of the reels 13L, 13M, and 13R, the number of sliding frames of the reels 13L, 13M, and 13R is determined so as not to win any of a plurality of roles, and the stop control of the reels 13L, 13M, and 13R is performed. .

  By the way, there is an upper limit on the number of sliding frames, and if the stop switches 21L, 21M, and 21R are not operated at the timing when the reels 13L, 13M, and 13R are at predetermined rotational positions, the stop control means 140 is Even if the lottery result by the lottery means 110 is winning of any of a plurality of roles, the reels 13L, 13M, 13R are displayed so that the symbols displayed on the display window 11 are stopped and displayed in a winning manner corresponding to the winning combination. Can not stop control. Therefore, in this embodiment, when the lottery result of the lottery means 110 is a winning combination for a special combination whose corresponding symbols are “red 7” and “BAR” among a plurality of roles, the reels 13L, 13M, 13R are selected. If the stop switches 21L, 21M, and 21R are not operated at the timings at which they are at the predetermined rotational positions, the stop control means 140 can stop and control the reels 13L, 13M, and 13R so as to win these winning combinations. Can not.

  In other words, when the lottery result of the lottery means 110 is a win for a special role among a plurality of roles, the stop control unit 140 stops the switch at a timing when the reels 13L, 13M, and 13R are at predetermined rotational positions, respectively. 21L, 21M, and 21R are operated on the display window 11 on the condition that a predetermined operation corresponding to these winning combinations is performed on the stop switches 21L, 21M, and 21R. The reels 13L, 13M, and 13R are controlled to stop so that the displayed symbols are stopped and displayed in a winning manner corresponding to each winning combination.

(9) Winning determination means 150
When the detection unit 130 detects that the predetermined symbol has stopped at a predetermined position, the winning determination unit 150 indicates that the symbol is stopped and displayed in a predetermined winning manner by the stop control unit 140. When it is detected, it is determined that a prize has been won.

  Specifically, the winning determination means 150 determines that the BB winning is achieved when three “red 7” symbols are aligned on the effective winning line, and determines that three “BAR” symbols are aligned on the effective winning line. Judged as RB winning Further, the winning determination unit 150 determines that a small role winning is achieved when three symbols of “bell”, “orange” or “cherry” are arranged on the winning line. In addition, the winning determination means 150 determines that a replaying role winning is achieved when three “Replay” symbols are arranged on the winning line.

(10) Dispensing control means 160
The payout control means 160 determines that the number of credit medals stored is the upper limit value (in this embodiment, if the winning determination means 150 determines that one of a plurality of winning combinations has been won, and if the medal is paid out) After reaching 50, for example, the hopper unit 43 is operated to pay out medals by the number of payouts corresponding to the winning combination. Also, the payout control means 160 increases the number of credit medals by the number of payouts instead of the operation of the hopper unit 43 as a medal payout until the number of stored credit medals reaches the upper limit value.

(11) Medal control means 102
The medal control means 102 controls the operation of the medal selector 48 to switch between medal acceptance and non-acceptance. Further, the medal control means 102 updates the bet number counter 651 or the credit number counter 652 if a medal detection signal is output from the insertion sensor 53 when the medal selector 48 can accept the medal.

  Specifically, when the value of the bet number counter 651 is 0 and the medal detection signal is output from the insertion sensor 53, the medal control unit 102 adds 1 to the bet number counter 651. Thereafter, the bet number counter 651 is incremented by one each time a medal detection signal is output from the insertion sensor 53 until the maximum number of medals per game is reached. In addition, the normal game control unit 100 or the special game control unit 101 refers to the bet number counter 651 to validate the winning line according to the number of inserted medals.

  Further, the medal control means 102 adds 1 to the credit number counter 652 when a medal insertion signal is output from the insertion sensor 53 in a state where the value of the bet number counter 651 is the maximum number of inserted coins.

(Operation)
Next, an example of the operation in this embodiment will be described with reference to FIGS. Although the operations described below are omitted from the various functions and means described above, the main CPU 61 of the main control board 63 and the sub CPU 71 of the sub control board 73 execute various programs. This process is executed by other functions.

1. Main Process FIG. 8 is a flowchart showing the main process. When the power of the slot machine 1 is turned on, the state of the RAM 65 included in the main control board 63 and the memory 75 included in the sub control board 73 is checked to determine whether or not an error has occurred in each memory. In this embodiment, when the power is turned on or when the setting control unit 170 performs setting change processing, the random number extraction unit 112 performs four random number extractions, and the extracted three Based on each random number value, preliminary lottery by the preliminary lottery means 114 is executed. The preliminary lottery results for four times are stored in the reel stop control lottery result storage means 653 in any order. The results of the preliminary lottery for four times are transmitted to the sub control board 73 via the sub control command transmission means 103 and stored in the effect lottery table 752 of the sub control board 73 in the same manner.

  Next, the check of each memory is completed, and if there is no abnormality, it shifts to the normal gaming state, it is determined whether or not a prescribed number of medals have been inserted (step S1), and waits until a prescribed number of medals are inserted. (NO in step S1). If it is determined that a prescribed number of medals have been inserted (YES in step S1), it is determined whether or not the start switch 19 has been operated (step S2).

  The system waits until the start switch 19 is operated (NO in step S2). If it is determined that the start switch 19 is operated (YES in step S2), the lottery means 110 described later with reference to FIG. A “lottery process” is performed (step S3), and rotation of each reel 13L, 13M, 13R is started (step S4).

  Next, it waits until each stop switch 21L, 21M, 21R corresponding to each rotating reel 13L, 13M, 13R is operated (NO in step S5), and any of the stop switches 21L, 21M, 21R is waited for. Is operated (YES in step S5), the rotation of the reel 13 corresponding to the operated stop switch 21 is stopped (step S6).

  Then, the processes from step S5 to step S7 are repeatedly executed until the rotation of all the reels 13 is stopped (NO in step S7). If all the reels 13 are stopped (YES in step S7), a prize is won. The determination unit 150 determines whether or not a prize has been won (step S8). If the determination result by the winning determination means 150 is a winning of any winning combination, a medal corresponding to the winning mode is paid out by the payout control means 160 (step S9), and the process is terminated.

2. Lottery Process FIG. 9 is a flowchart showing the lottery process. The lottery process shown in FIG. 9 is a process executed in step S3 of the main process shown in FIG. 8, and first, random number extraction means 112 extracts random values (step S101). Next, the result of preliminary lottery four games (predetermined number of games) stored in the reel stop control lottery result storage unit 653 is read (step S102), and the random number value 2 extracted by the random number extraction unit 112 is read. The final lottery by the final lottery 114 is executed using the value represented by the bit, and the first special combination and the first special combination are determined by the lottery determination unit 115 based on the read preliminary lottery result and the final lottery result It is determined whether or not one of the second special roles is won (step 103).

  Subsequently, the preliminary lottery and the general lottery are performed by the preliminary lottery unit 113 using the value represented by 16 bits of the random number extracted by the random number extraction unit 112, and the lottery determination unit 115 is based on the result of the general lottery. Thus, it is determined whether or not one of the first to third small roles and the re-playing role is won (step S104). Then, the preliminary lottery result and the determination result based on the result of the general lottery and the final lottery result by the lottery determination unit 115 are stored in the reel stop control lottery result storage unit 653 (step S105). The determination result based on the result of the general lottery by the lottery determination unit 115 and the result of the final lottery is transmitted to the sub control board 73 via the sub control command transmission unit 103, and the lottery result for effect control of the sub control board 73 is stored. It is stored in the means 751 (step S106).

3. Effect Control Process FIG. 10 is a flowchart showing the effect control process. This process is a process for controlling the effect based on the result of the preliminary lottery transmitted by the sub-control command transmitting means 103 and received via the sub-control command receiving means 104 and stored in the effect control lottery result storage means 751. The result of the preliminary lottery in the current game and the result of the lottery determination unit 115 based on the result of the general lottery and the result of the final lottery in the current game are received via the sub-control command receiving unit 104 (step S201) and stored in the effect control lottery result storage means 751 (step S202). And the result of the preliminary lottery in the game of 4 times memorize | stored in the lottery result storage means 751 for effect control is acquired (step S203).

  Next, based on the acquired preliminary lottery result, the effect lottery means 105a executes the effect lottery to select the effect group (step S204), and the effect lottery based on the effect determination lottery table of the selected effect group. The effect to be executed is determined (step S205), and the effect based on the result of the effect lottery is executed (step S206).

  As described above, according to this embodiment, when a single game (game) is executed based on a player's operation on condition that a prescribed number of medals (game media) are inserted. In addition, a lottery including determination as to whether or not a specific lottery result (first special role, second special role) having a win probability P has been won is performed by the lottery means 110, and based on the lottery result by the lottery means 110, The display results of the symbols in the game on the reels 13L, 13M, and 13R that variably display a plurality of types of symbols are controlled by the stop control means 140, and an effect is given to the player by the effect control means 105.

  The determination by the lottery means 110 whether or not a specific lottery result (first special role, second special role) having a winning probability P has been won is determined by the winning probability P = preliminary winning probability Pa (1> Pa> P ) × Confirmed winning probability Pb (1> Pb> P) is satisfied, the preliminary lottery means 113 determines whether or not the preliminary lottery with the preliminary winning probability Pa is won for each game. In the game to be executed after the predetermined number of games (4 games), the determination lottery means 114 determines whether or not the final lottery with the final determination probability Pb has been won. If the result of the preliminary lottery in the game executed before the predetermined number of games (4 games) of the game in which the final lottery is performed is a win, a specific lottery result (first special role, first game) having a win probability P (2 special roles) It is determined by the step 115.

  Therefore, the probability of winning the final lottery with the final winning probability Pb is greater than the probability of winning the specific lottery result (first special role, second special role) that is the win probability P, and the game in which the final lottery has been performed It is determined whether or not there is a possibility of winning a specific lottery result (first special combination, second special combination) according to the result of preliminary lottery in a game executed before the predetermined number of games (4 games). Therefore, the production control means 105 wins a specific lottery result (first special role, second special role) having a winning probability P by using the result of preliminary lottery with the winning probability Pa by the preliminary lottery means 113. It is possible to execute a highly reliable performance on the probability.

  In addition, whether or not a specific lottery result (first special role, second special role) is won is determined by a game executed after a predetermined number of games (4 games) in which a preliminary lottery is performed. The final lottery 114 confirms the final lottery. Therefore, even if the player finishes the game after the game in which the preliminary lottery is performed until the final lottery is executed, whether or not the specific lottery result (first special role, second special role) is won Such a determination is not fixed, and the player is not disadvantaged. That is, the effect control means 105 executes an effect using the result of the preliminary lottery by the preliminary lottery means 113, thereby executing a highly reliable effect related to a specific lottery result without being disadvantageous to the player. Can do.

  In addition, whether or not a specific lottery result (first special role, second special role) has been won is determined by the lottery determination means 115 based on the result of the final lottery in the current game. In each game, the game is not executed in a so-called race state as in the past, and a highly reliable performance related to a specific lottery result can be executed in a state where the fairness of the game is ensured. it can.

  Further, the preliminary lottery means 113 determines whether or not the preliminary lottery with the preliminary winning probability Pa is won, and other lottery results different from the specific lottery results (first special role, second special role) ( Since the general lottery for determining whether or not the first to third small combinations and replaying combinations) have been won is performed, the processing efficiency can be improved.

  Further, the preliminary lottery result of the preliminary lottery means 113 in the game for the latest predetermined number of games (4 games) is stored in the reel stop control lottery result storage means 653 of the lottery means 110, and the lottery determination means 115 is For each game, among the preliminary lottery results stored in the reel stop control lottery result storage means 653, a specific lottery result (first special combination, It is determined whether or not the second special role is won, and other lottery results (first to third small roles, replaying role) are won based on the result of the general lottery in the current game. With this determination, the stop control means 104 controls the reels 13L, 13M, 13R to stop for each game based on the result of the preliminary lottery and the result of the lottery determination means 115 based on the result of the general lottery. Player's interest because it can be different can be enhanced.

  In addition, the result of preliminary lottery of the preliminary lottery means 113 in the game for the latest four games including the current game and the result of determination of the lottery determination means 115 in the current game are stored in the lottery result for effect control of the effect control means 105. By storing in the means 751, the effect control means 105 is practical because it can perform effects based on the preliminary lottery result stored in the effect control lottery result storage means 751 and the determination result of the lottery determination means. is there.

  In addition, when the random number extraction unit 112 extracts the random number for (2 + 16) bits that the random number generation unit 111 generates, once the random number is extracted by the random number extraction unit 112, the preliminary lottery unit 113 Preliminary lottery and general lottery can be performed using a value represented by 16 bits of the random number extracted by the extraction means 112, and the final determination lottery means 114 is for 2 bits of random numbers extracted by the random number extraction means 112. Since the final lottery can be performed using the value represented by

  Further, in this embodiment, the lottery determination unit 115 determines the result of the preliminary lottery by the preliminary lottery unit 113 before 4 games stored in the reel stop control lottery result storage unit 653 and the confirmation of the final lottery unit 114 in the current game. Based on the result of the lottery, it is determined whether or not a specific lottery result (first special role, second special role) has been won, and based on the result of the general lottery by the preliminary lottery means 113 in the current game. Then, it is determined whether or not other lottery results (first to third small roles, re-game players) have been won. Accordingly, when the result of the preliminary lottery by the preliminary lottery means 113 before the four games is a win and the result of the general lottery by the preliminary lottery means 113 for the current game is a win, the confirmation of the final lottery means 114 in the current game If the lottery result is a win, both the specific lottery result (first special role, second special role) and other lottery results (first to third small roles, re-playing role) are determined by the lottery determination means 115. It is determined that was won. Thereby, depending on the operation timing of the player's stop switches 21L, 21M, and 21R, the player's willingness to the winning combination different from the winning combination predicted by the effect by the effect control means 105 based on the determination result of the lottery determination means 115. Contrary to this, there are cases where a prize is won, and the interest of the player can be enhanced.

<Second Embodiment>
A second embodiment of the present invention will be described with reference to FIG.

  This embodiment is different from the first embodiment described above in that the lottery determination unit 115 determines the final lottery in the lottery process step S103 shown in FIG. Of the stored results of the general lottery of the preliminary lottery means 113, other lottery results (first small role to third small role, re-playing role) based on the result of the general lottery before 4 games (predetermined number of games). It is a point to determine whether or not is won.
