Description

  The present invention relates to a gaming machine that is installed and used in a game hall such as a pachinko parlor.

  In this specification, a pachislot machine is described as an example of one of the gaming machines. Therefore, a description will be given using a medal as a gaming medium for playing a game, but the gaming medium may be other media such as a pachinko ball. Including. In addition, “inserting a medal” includes not only actually inserting a medal into the medal insertion slot but also inserting (betting) a credited medal with a bet button or the like. In addition, a lottery that determines either a loser or multiple types of winning roles is selected as a winning role lottery, and the symbols that make up the winning roles are aligned on the winning line, and the winning role is selected by winning the winning role lottery. The state until winning a prize is considered as an internal prize.

  A slot machine installed and used in a game hall such as a pachinko parlor is called a pachislot machine, and given a certain value to medals, the medals earned by playing the game can be exchanged for various prizes. Generally, in a slot machine, a medal is played in a normal mode in which a game is played by betting 1 to 3 medals, or in a big bonus (hereinafter referred to as BB) mode or a regular bonus (hereinafter referred to as RB) mode. There are bonus game modes that make it easier to earn.

  In the RB mode, a game is played by betting one medal, and the payout rate is higher than in the normal mode. The BB mode is shifted to the RB mode a plurality of times. Further, in the BB mode, the system shifts to the RB introduction mode in which whether or not to shift to the RB mode before the RB mode is determined by lottery. In the RB introduction mode, a game is played by betting three medals, and the winning combination of the small role to which medals are paid out becomes higher than in the normal mode. The BB mode ends when a predetermined number of transitions are made to the RB mode, or when a game is played a predetermined number of times in the RB introduction mode. For this reason, in the BB mode, more medals can be obtained if more games are played in the RB introduction mode while shifting to the RB mode a predetermined number of times. For these reasons, in a recent slot machine, when it is determined to shift to the RB mode in the RB introduction mode, for example, when the stop button is pressed in a specific order different from the normal order, the transition to the RB mode is performed. The ones with carry-over functions that carry over their rights are the mainstream. In such slot machines, most of the winning small prizes are awarded when the stop buttons are pressed in a specific order. Then, in the RB introduction mode, the player first presses the stop button so as not to shift to the RB mode, and when the number of games in the RB introduction mode reaches the upper limit, the player presses the stop button in a regular order to select the RB mode. To migrate. Thereby, in the BB mode, it becomes possible to acquire a larger amount of medals than in the past. For this reason, slot machines having a carry-over function have gained tremendous popularity from players, and in recent years, many such slot machines tend to be provided.

  Transition to the BB mode or the RB mode is made when BB or RB is won in the winning combination lottery performed in the normal mode and these are further won. By the way, in the slot machine, when the winning symbol (the symbol constituting the winning combination won in the winning combination lottery) is located within the preset pull-in range, if the stop button is pressed, the reel stops so that the winning combination wins Control is taking place. For this reason, when winning a BB or RB, if the BB symbol constituting the BB or the RB symbol constituting the RB is not located within the pull-in range, they cannot be won. However, in the slot machine, if a player cannot win BB or RB, the player loses a lot of money. Therefore, the right won for these will be carried over to the next game and the next game. It is common for games to be in a state where BB or RB has won an internal prize. However, in a state where BB or RB has won an internal prize, a lottery of BB or RB is not performed, or even if BB or RB is won, a process such as cancellation is performed. It was a cause of increased unfairness.

For this reason, for example, Patent Document 1 shows a so-called stock function in which BB and RB won during the internal winning of BB and RB are stored, and BB and RB stored in subsequent games are released. In addition, slot machines having a stock function are also provided in the market, and in a slot machine having a stock function, if a plurality of stored BBs and RBs are released in a short period, the player It has gained enormous popularity from players because it can earn enormous amounts of medals.
JP 2001-104543 A

  However, a slot machine with a stock function can win a huge amount of medals in a short period of time as described above. You will be scolded, and it may damage the health of the game. Under such circumstances, for example, prohibiting the adoption of the stock function under the voluntary regulations by the customs business law and slot machine manufacturers is being considered. Furthermore, in order to prevent the carry-over function from giving excessive profits to the player in the BB mode, an upper limit is set on the number of medals to be paid out in the BB mode. In addition, in the RB introduction mode, It has been considered to set the winning probability of the small role to be the same as the normal mode. However, under such regulations, the number of medals that a player can acquire becomes uniform and the game becomes monotonous, which may cause the player to lose interest in the slot machine.

  In order to solve the above problems, an object of the present invention is to provide a gaming machine capable of preventing a game from becoming monotonous.

  In order to achieve the above object, the gaming machine according to claim 1, wherein a plurality of types of symbols are arranged, and a reel that stops in response to a player's stop operation and one of a plurality of types of winning combinations or loses are won. A winning combination determining means for determining by combination lottery, a normal mode, a special mode in which the player has an advantage over the normal mode, a player to have an advantage over the normal mode, and separate from the special mode When the game is performed in the second special mode, and the special winning combination is won in the winning combination lottery, the normal mode is changed to the special mode, and when the reels stop, When the second special mode transition symbol is stopped, the gaming machine shifts from the normal mode to the second special mode, and the second special mode transition symbol is stopped on the winning line. A number-of-games determining means for determining the number of games in the normal mode until reaching a stoppable game that can be played, and a number-of-games counting means for counting the number of games in the normal mode And an input number determination means for performing an input lottery for determining the input number of game media that can stop the second special mode transition symbol on the winning line in the stoppable game, and the input lottery When the determined number of game media has been inserted and a game in the stoppable game has been performed, the reel stop control is performed so that the second special mode transition symbol stops on the winning line. And a reel stop control means for performing.

  According to the first aspect of the present invention, when a game that can be stopped in the normal mode is reached and a game in the game that can be stopped is performed by inserting the number of game media determined by the insertion lottery, Since the reels are controlled to stop on the winning line, if the results in the number of games draw are biased, the frequency of shifting to the special mode can be biased and the game becomes monotonous. Can be prevented.

  First, the external appearance of the slot machine 10 of the first embodiment is shown in FIG. 1, and an outline of the game flow of the slot machine 10 will be described. In the slot machine 10 shown in FIG. 1, two types of game modes, that is, a normal mode and a BB mode (“special mode” described in claim 1) are set. If a BB that gives the right to shift to the BB mode ("specific winning combination" described in claim 1) is won in the winning combination lottery in the normal mode and BB is won, the BB mode is shifted from the normal mode. In the normal mode, the game is played with 3 medals (the first inserted number), but the winning combination is the 0-sheet role (the inserted number variable role) where the medals are not paid out, and this is won. Then, in the next game, one medal (second input number) is inserted and the game is played. When a game is played with one medal inserted, the BB winning probability is higher than when a game is played with three medal inserted. The BB mode ends when the number of medals paid out reaches 465.

  The BB mode includes an RB mode (special game) in which whether or not to win a bonus combination with payout of medals is determined for each game, and an RB introduction mode (general game) shifted before the RB mode. . In the normal mode and the RB introduction mode, the type of winning combination for each game mode is set so that the bonus combination is not won.

  In the RB mode, a game is played by betting one medal, and the winning probability of the bonus combination is set so that the bonus combination is won in most games. Thereby, the payout rate is higher in the RB mode than in the normal mode, and the player is more advantageous. In the RB introduction mode, a game is played by betting three medals, and the winning probability of the small role for which medals are paid out is set to be the same as in the normal mode. Then, replay in the RB introduction mode (in this embodiment, the winning combination lottery also serves as a lottery for determining whether or not to shift to the RB mode, and when the replay is won in the winning combination lottery, the RB mode is entered. RB mode is selected, the RB mode is entered.

  The slot machine 10 is provided with a housing 10 a including a storage box 11 and a front door 12. A display window 13 is provided on the front door 12. A first reel 14a, a second reel 14b, and a third reel 14c are rotatably incorporated in the back of the display window 13. A plurality of types of symbols are arranged at regular intervals on the outer circumferences of the first to third reels 14a to 14c. When the first to third reels 14a to 14c are stopped, three symbols per reel can be observed through the display window 13. A total of five straight winning effect lines 15 in which the symbols of each reel are combined one by one and three by two are set.

  When one medal is inserted from the medal slot 16, the middle winning effective line 15 is activated. When two medals are inserted, the three horizontal winning effective lines 15 obtained by adding the upper and lower winning effective lines 15 to the middle winning effective line 15 are activated. When three medals are inserted, a total of five winning active lines 15 are activated by adding two diagonal lines to the upper, middle and lower tiers.

  In the slot machine 10, it is possible to credit (store) medals up to 50. The number of credited medals is displayed on the credit number display unit 17.

  When the start lever 18 is pressed, the first to third reels 14a to 14c start to rotate all at once. When a certain time has elapsed since the rotation of the first to third reels 14a to 14c has started, the operation of the stop buttons 19a to 19c (reel stop operation) is validated. When the operation of the stop buttons 19a to 19c is validated, the corresponding first to third reels 14a to 14c are individually stopped in response to the press of the stop buttons 19a to 19c.

  A medal tray 20 is provided below the front door 12. When the winning combination wins the medal tray 20, the number of medals corresponding to the type of the winning combination is paid out from the payout slot 21.

  A liquid crystal panel 22 is provided above the display window 13. From the liquid crystal panel 22, for example, an effect display indicating the result of the winning combination lottery is displayed by characters or characters.

  As shown in FIG. 2, the operation of the slot machine 10 is basically performed by a control unit 30 including a CPU (“input number variation means” according to claim 1 and “table selection means” according to claim 1) 30 a and a memory 31. Controlled by. In addition to the CPU 30a and the memory 31, the control unit 30 is provided with an electronic lottery unit 39 and a winning combination determining unit 40 which will be described later. The electronic lottery unit 39 and the winning combination determining unit 40 constitute a winning combination determining means according to claim 1.

  The medal sensor 32 detects an appropriate medal inserted from the medal slot 16, and inputs a medal detection signal to the CPU 30a. The CPU 30a counts the number of inserted 1 to 3 medals based on the detection signal from the medal sensor 32, and determines the number to activate the winning effective line 15.

  The start signal sensor 33 detects that the start lever 18 has been pressed. When pressing of the start lever 18 is detected, a game start signal is input from the start signal sensor 33 to the CPU 30a. The CPU 30a rotates the first to third reels 14a to 14c in response to the game start signal, and starts game processing according to the program stored in the ROM area of the memory 31.

  The drive and stop control of each reel is performed by the CPU 30a and the reel drive controller 34. The CPU 30a and the reel drive controller 34 constitute reel stop control means. The first to third reels 14a to 14c are attached to the drive shafts of the stepping motors 35a to 35c, respectively. The first to third reels 14a to 14c are controlled by controlling the driving of the stepping motors 35a to 35c. The RAM area of the memory 31 is used for temporary storage or rewriting of flags and data used for each game.

  The stepping motors 35a to 35c rotate at a rotation angle corresponding to the number of drive pulses supplied from the CPU 30a. For this reason, the CPU 30a controls the rotation angle of the first to third reels 14a to 14c by controlling the number of drive pulses supplied to the stepping motors 35a to 35c, and stops the reels by stopping the supply of the drive pulses. Determine the position. The first to third reels 14a to 14c are integrally formed with reflection signal portions 36a to 36c at their reference positions. Each time the first to third reels 14a to 14c make one rotation, the photosensors 37a to 37c detect the passage of the respective reflection signal portions 36a to 36c. Detection signals from the photosensors 37a to 37c are input to the CPU 30a as a reset signal indicating the reference position of the reel.

  The CPU 30a is provided with a pulse counter that counts the number of drive pulses supplied to each of the stepping motors 35a to 35c. When a reset signal is input from the photosensors 37a to 37c, the CPU 30a clears the count value of the corresponding pulse counter. Therefore, the number of drive pulses corresponding to the rotation angle within one rotation of each reel is stored in each pulse counter while being sequentially updated.

  A symbol table is stored in the ROM area of the memory 31. In the symbol table, the number of drive pulses corresponding to the rotation angle from the reference position of each reel is associated with symbol codes indicating symbols arranged on the first to third reels 14a to 14c. The CPU 30a can identify, for example, which symbol has moved on the winning winning line 15 in the middle stage by monitoring the count value of the pulse counter for each reel while referring to this symbol table, and which If the reel is rotated to some extent, it can be predicted whether the target symbol will move on the winning effective line 15.

  When the rotation of the first to third reels 14a to 14c is started and the rotation speed of the first to third reels 14a to 14c reaches a steady speed, the CPU 30a validates the operation of the stop buttons 19a to 19c. When the stop buttons 19a to 19c are pressed and a stop signal is input, the CPU 30a and the reel drive controller 34, based on the winning combination lottery result, the first to third reels 14a to 14c corresponding to the stop buttons 19a to 19c. Perform stop control. Stop control of the first to third reels 14a to 14c is performed by a table system using a stop table.

  The outer peripheral surfaces of the first to third reels 14a to 14c are partitioned into a plurality of frames for each predetermined range. One symbol is assigned to each frame. In the ROM area of the memory 31, a plurality of stop tables referred to by the CPU 30a are stored.

  The stop table is referred to one of a plurality of times each time the stop buttons 19a to 19c are pressed. In the stop table, when the stop buttons 19a to 19c are pressed, the symbol code of the symbol located on the winning winning line 15 and the number of frames required for the first to third reels 14a to 14c to stop at this time are shown. Are associated. Then, when the stop buttons 19a to 19c are pressed, the CPU 30a refers to the stop table and determines the type of symbols to be stopped on the winning winning line 15.

  In the stop table, the number of frames required until the first to third reels 14a to 14c are stopped ranges from 0 to 4 frames for 5 symbols including symbols on the winning winning line 15, that is, a range of 5 frames (hereinafter referred to as “ (Referred to as “retraction range”). For this reason, stop control of the first to third reels 14a to 14c is performed within a range of five frames. When the stop buttons 19a to 19c are pressed, the winning symbol (the symbol corresponding to the winning combination won in the winning combination lottery) is included in the four consecutive frames from the frame positioned on the winning winning line 15. If so, the stop table is selected so that the winning symbol can be stopped on the winning winning line 15. In this way, the stop control for stopping the symbol located within the drawing range on the winning winning line 15 is referred to as drawing control.

  In the stop table, the pull-in range changes depending on the type of the winning combination won, the order in which the first to third reels 14a to 14c are stopped, and the type of symbols already stopped on the winning pay line 15. A stop table is selected.

  Further, when the stop buttons 19a to 19c are pressed so that the winning combination wins when the winning combination is not won, the stop table is selected so that no winning is generated. That is, a stop table is selected that stops symbols that are not won in combination with symbols that have already stopped. As a result, the winning combination that has not been won in the winning combination lottery cannot be won. Thus, the stop control for stopping the symbol on the winning winning line 15 so that the winning combination does not win is referred to as kicking control.

  The stop control of the first to third reels 14a to 14c is performed by, for example, determining the priority order of symbols to be stopped on the winning winning line 15 according to the type of the winning combination won and the timing when the stop buttons 19a to 19c are pressed. You may carry out by appropriate methods, such as the algorithm method to determine. In this case, when the stop buttons 19a to 19c are pressed, the symbol having the highest priority within the pull-in range is stopped on the winning pay line 15.

  When a game start signal is input from the start signal sensor 33, the CPU 30a operates the electronic lottery unit 39. The electronic lottery unit 39 includes a random number generator and a random number sampling circuit, and draws one random value every time a game is started. The random value selected by lottery is input to the winning combination determining unit 40.

  The winning combination determining unit 40 includes a first normal table (a “lottery table” according to claim 1) 40a for determining a winning combination in a game in which three medals in the normal mode are inserted and a game in the RB introduction mode, the normal mode A second normal table ("lottery table" according to claim 1) 40b for determining a winning combination in a game in which one medal is inserted, and an RB table (not shown) for determining a winning combination in the RB mode. Yes.

  The first normal table 40a and the second normal table 40b are a BB that grants a right to shift to the BB mode to each random number generated by the random number generator of the electronic lottery unit 39, a small part with a medal payout, a replay, Either a 0-piece combination or a loss is assigned. The first normal table 40a and the second normal table 40b are different in the number of random number values to which the BB is assigned so that the BB winning probabilities are different from each other, whereby the second normal table 40b is changed to the first normal table 40a. The winning probability is set so that the winning probability of BB is higher than that.

  In the RB table, either a bonus combination or a loss is assigned. In the RB table, a bonus combination is assigned to most random numbers. That is, in the RB mode, the winning probability is set so that the bonus combination is won in most games. The payout rate is set so that the player is more advantageous in the RB mode game than in the normal mode by setting the bonus winning probability in this way.

  In the winning combination determining unit 40, the random number value drawn by the electronic lottery unit 39 is checked against any one of the first normal table 40a, the second normal table 40b, and the RB table according to the game mode being transferred. Thereby, a winning combination or a loss is determined in each game mode. The type of table used in the winning combination lottery is determined by a table selection signal input from the CPU 30a to the electronic lottery unit 39. The first normal table 40a is used in the normal mode and the RB introduction mode, but this is invalidated when BB is won in the RB introduction mode. That is, stop control of the first to third reels 14a to 14c is performed so that the BB does not win even if BB is won in the RB introduction mode.

  The hopper device 41 pays out a specified number of medals to the medal tray 20 when a small combination or bonus combination is won, or adds the specified number to the credit counter. A payout table that determines the number of medals to be paid out is stored in the ROM area of the memory 31. The CPU 30a reads the payout number from the payout table and drives the hopper device 41.

  Next, the operation of the slot machine configured as described above will be described. As shown in FIG. 3, in the slot machine 10, first, three medals are inserted and a game in the normal mode is performed. When three medals are inserted prior to the start of the game, the number of inserted medals is counted by the CPU 30a. When the player operates the start lever 18, a game start signal is input from the start signal sensor 33 to the CPU 30a, and rotation of the first to third reels 14a to 14c is started.

  When the start lever 18 is operated, the winning combination lottery is performed by the electronic lottery unit 39 and the winning combination determining unit 40. In the winning combination determining unit 40, the random number value drawn by the electronic lottery unit 39 is checked against the first normal table 40a.

  When the winning combination lottery is completed and the first to third reels 14a to 14c start to rotate and a certain time has elapsed, the operation of the stop buttons 19a to 19c is validated. When the stop buttons 19a to 19c are pressed, the CPU 30a and the reel drive controller 34 monitor the timing when the stop buttons 19a to 19c are pressed while referring to the count value of the pulse counter provided for each reel, and the winning symbol is displayed. Stop control of the first to third reels 14a to 14c is performed so as to easily stop on the winning effective line 15.

  When the winning combination lottery is won and the winning combination is won, the CPU 30a inputs a table selection signal indicating the second normal table 40b to the electronic lottery unit 39. In response to this, the electronic lottery unit 39 performs the winning combination lottery using the second normal table 40b in the next game. As a result, the winning probability of BB is increased in the game after winning the 0-piece combination. In the next game, the CPU 30a accepts only one medal. For this reason, the inserted second and subsequent medals are not detected by the medal selector and are returned to the player. As a result, in the game after winning 0 winning combination, the game is played by inserting one medal. When inserting a credited medal, the operation of the credit button is invalidated after the first medal is bet.

  When BB is won in the winning combination lottery and the player wins BB, the CPU 30a reads the execution program in the BB mode from the ROM area of the memory 31 and shifts from the normal mode to the BB mode.

  When winning a small combination or SB in the BB mode, the CPU 30a writes the cumulative number of medals assigned to these winning combinations in the RAM area of the memory 31 and accumulates them. Thereby, the number of medals paid out to the player in the BB mode is managed.

  When shifting to the BB mode, a game in the RB introduction mode is first performed. In the RB introduction mode, the winning combination lottery is performed using the first normal table 40a. For this reason, in the RB introduction mode, the winning probability of the small role is the same as that in the normal mode. When the number of medals acquired by the player in the RB introduction mode reaches 465, the BB mode is terminated before the RB mode is entered. When winning the replay in the RB introduction mode, the CPU 30a reads the execution program in the RB mode from the ROM area of the memory 31, and shifts from the RB introduction mode to the RB mode.

  In the RB mode, the winning combination lottery is performed using the RB table. For this reason, in the RB mode, it is determined whether or not SB is won. The RB mode continues until the number of medals acquired by the player reaches 465. When the number of medals acquired by the player in the RB mode reaches 465, the BB mode ends.

  In the first embodiment, a plurality of winning probabilities are not set. However, when a plurality of winning probabilities are set and a game is played in the normal mode, a predetermined condition is satisfied. You may switch the winning probability. For example, it is preferable to perform the kicking control of the 0-sheet winning symbol so that the 0-number winning combination is not won in several games after the winning of the 0-sheet winning. Thereby, for example, by using the liquid crystal panel 22, it is possible to execute a continuous effect that informs the player that the winning combination of 0 sheets is skipped over several games in which the control is performed, and the player's expectation for winning the BB is achieved. Can be increased.

  In the first embodiment, the RB mode is set as a special game. However, as a special game, for example, at least one of the first to third reels 14a to 14c is in a no-control state (no reel stop control is performed). , A challenge time (CT) mode in which the stop button is pressed according to the timing at which the stop button is pressed, a replay time (RT) mode in which the winning probability of replay is higher than the normal mode, and a high probability of transition to the RT mode. RT transition high probability mode, to notify the order of pressing the stop button, or to notify the symbols to be stopped on the winning effective line 15, by prompting the player to perform a specific winning combination, such as Assist time (AT) mode that allows you to win a prize, AT transition high probability mode that increases the transition probability to AT mode The stock time (ST) mode that stores the winning combination when it wins a specific winning combination, the high release probability mode that increases the release probability of the stored winning combination, and the bonus combination is drawn only for one game. An appropriate game mode may be set if the player has an advantage, such as a single bonus (SB) mode and a SB high probability mode in which the probability of transition to the SB mode is increased by a game of a certain section.

  In the first embodiment, the BB mode is shifted to the RB introduction mode and the RB mode once each. However, for example, the RB introduction mode and the RB mode may be repeatedly shifted a plurality of times. Further, for example, two types of BB modes configured by an RB introduction mode, an RB mode, and an RB introduction mode and a CT mode may be set, and which BB mode to shift to may be determined at the time of BB winning.

  In the first embodiment, when the replay is won in the RB introduction mode, the mode is changed to the RB mode. However, when an appropriate condition is satisfied, for example, when a predetermined number of games are performed in the RB introduction mode. The RB introduction mode may be shifted to the RB mode.

  FIG. 4 shows an example in which a recording medium (CD, flexible disk, IC memory, MO, etc.) 100 is installed in the slot machine 10, and the recording medium 100 has means as shown in the flowchart of FIG. The program for implement | achieving by the computer 101 containing 31 is stored. In this case, for example, a winning combination deciding means for determining one of a plurality of types of winning combinations or losing by a winning combination lottery, and a plurality of lottery tables used in the winning combination lottery and having different winning probabilities for the specific winning combination. The reel stop control is performed to stop the reels so that when the winning number winning combination is won in the winning combination lottery, the inserted number changing symbols of a plurality of types can be stopped on the winning line. When the stop operation is performed so that the control means and the inserted number variation symbol stop on the winning line, a second inserted number of game media different from the first inserted number is inserted. In the case where the game is performed by inserting the second inserted number of game media, and the first inserted number of the first inserted number in the normal mode. Game Special mode consisting of a general game with the same winning probability as the normal mode and a special game in which the player has an advantage over the normal mode. A program for causing the computer 101 to function as table selection means for performing the lottery winning lottery is recorded on the recording medium 100 using the lottery table having a high winning probability of the specific winning combination that triggers the transition to. Then, the recording medium 100 is loaded into the reading device 102 and the program is installed in the slot machine 10.

  The program can be distributed to the slot machine 10 using the Internet instead of being installed via the recording medium 100. It is also possible to install the distributed program of the present invention or the program of the present invention read from the recording medium 100 in a personal computer and play a slot machine game on a monitor.

  Next, a second embodiment will be described. In the second embodiment, the RB introduction mode ends when the upper limit number of games determined in the game number lottery is performed. Note that the same reference numerals are used for functional units having the same functions as those in the first embodiment, and detailed descriptions thereof are omitted.

  As shown in FIG. 5, in the slot machine 10 of the second embodiment, a game number determining unit (game number determining means according to claim 2) 41 for determining the upper limit number of games in the RB introduction mode and the RB introduction mode The control unit 30 is provided with a game number counting unit (game number counting means according to claim 2) for counting the number of games in the game.

  The number-of-games determination unit 41 is activated in response to winning of BB. The number-of-games determination unit 41 performs lottery of games, and determines the upper limit number of games in the RB introduction mode by lottery. The result of the game number lottery is fed back to the CPU (game control means).

  The game number counting unit 42 is operated in the RB introduction mode. The CPU 30 a sets (writes) the upper limit number determined by the game number determination unit 41 in the game number count unit 42. The CPU 30a decrements the value of the game number counting unit 42 every time a game is started in the RB introduction mode. Thereby, the number of games in the RB introduction mode is counted. The CPU 30a monitors the number of games in the RB introduction mode, and ends the RB introduction mode when the number of games in the RB introduction mode reaches the upper limit number determined in the game number lottery. Note that the game number counting unit 43 may count up the number of games in the RB introduction mode, end the RB introduction mode when the count value reaches the upper limit number, and reset the count value.

  Next, the flow of the game in the second embodiment will be described with reference to FIG. 6. Since the game is performed in the normal mode in the same flow as in the first embodiment, the flow of the game in the normal mode will be described. The flow of the game after winning the BB mode will be described.

  When BB is won in the winning combination lottery and the player wins BB, the CPU 30a reads the execution program in the BB mode from the ROM area of the memory 31 and shifts from the normal mode to the BB mode. When the BB mode is won, the game number determination unit 42 is activated. In the game number determination unit 42, a game number lottery is performed. Thereby, the upper limit number of games in the RB introduction mode is determined. The determined upper limit number is set in the game number counting unit 43.

  When winning a small combination or bonus combination in the BB mode, the CPU 30a writes the cumulative number of medals assigned to these winning combinations in the RAM area of the memory 31 and accumulates them. Thereby, the number of medals paid out to the player in the BB mode is managed.

  When shifting to the BB mode, a game in the RB introduction mode is first performed. In the RB introduction mode, the winning combination lottery is performed using the first normal table 40a. For this reason, in the RB introduction mode, the winning probability of the small role is the same as that in the normal mode. Further, when a game is played in the RB introduction mode, the value of the game number counting unit 43 is decremented. When the number of medals acquired by the player in the RB introduction mode reaches 465, the BB mode is terminated before the RB mode is entered. When the value of the game number counting unit 43 becomes “0”, the CPU 30a reads the execution program in the RB mode from the ROM area of the memory 31, and shifts from the RB introduction mode to the RB mode.

  In the RB mode, the winning combination lottery is performed using the RB table. Therefore, in the RB mode, it is determined whether or not a bonus combination is won. The RB mode continues until the number of medals acquired by the player reaches 465. When the number of medals acquired by the player in the RB mode reaches 465, the BB mode ends.

  As described above, in the second embodiment, since the frequency of shifting to the RB mode is biased depending on the number of games in the RB introduction mode, the number of medals acquired by the player can be biased. In addition, since the number of games until the transition to the RB mode is determined in advance, it is possible to perform a continuation effect over a plurality of games and a precursor effect suggesting the transition to the RB mode before the transition to the RB mode. .

  In the second embodiment, the RB mode is set as a special game. However, as a special game, for example, at least one of the first to third reels 14a to 14c is in a no-control state (no reel stop control is performed). , A challenge time (CT) mode in which the stop button is pressed according to the timing at which the stop button is pressed, a replay time (RT) mode in which the winning probability of replay is higher than the normal mode, and a high probability of transition to the RT mode. RT transition high probability mode, to notify the order of pressing the stop button, or to notify the symbols to be stopped on the winning effective line 15, by prompting the player to perform a specific winning combination, such as Assist time (AT) mode that allows you to win a prize, AT transition high probability mode that increases the transition probability to AT mode The stock time (ST) mode that stores the winning combination when it wins a specific winning combination, the high release probability mode that increases the release probability of the stored winning combination, and the bonus combination is drawn only for one game. An appropriate game mode may be set if the player has an advantage, such as a single bonus (SB) mode and a SB high probability mode in which the probability of transition to the SB mode is increased by a game of a certain section.

  In the second embodiment, the BB mode is shifted to the RB introduction mode and the RB mode once, but may be repeatedly shifted to the RB introduction mode and the RB mode a plurality of times, for example. In this case, the number-of-games lottery may be performed every time the RB introduction mode is started, and the termination condition of the RB mode may be set as appropriate. Further, for example, two types of BB modes configured by an RB introduction mode, an RB mode, and an RB introduction mode and a CT mode may be set, and which BB mode to shift to may be determined at the time of BB winning.

  In the second embodiment, the number of games in the RB introduction mode is drawn with a certain probability. However, the probability of the number of games to be drawn may be changed according to the gaming state. In this case, it can be realized by providing a plurality of game number tables which are used in the game number lottery and have at least one winning probability for each number of games different from each other. Then, a game number table may be selected according to the game state, and a game number lottery may be performed using the selected game number table.

  Thus, for example, in the BB mode in which a plurality of RB modes are set, if a game number table is selected in which the number of games in the RB introduction mode is likely to be relatively small, a plurality of games in the RB mode are selected in a short period of time. Since it can be performed once, the number of medals acquired by the player can be biased. As a trigger for selecting a game number table with a small number of games, for example, when the BB mode is ended during the RB mode, or when two types of BB modes are set as described above, the CT mode It may be set at an appropriate timing, for example, when the BB mode including

  Next, a third embodiment will be described. In the third embodiment, even in the RB introduction mode, a lottery of 0 sheets is performed, and when the 0 sheet combination wins, the RB introduction mode ends and the RB mode is entered. Note that the same reference numerals are used for functional units having the same functions as those in the first embodiment, and detailed descriptions thereof are omitted. Further, in the third embodiment, the 0-piece role symbol constitutes the “special game transition symbol” according to claim 3, the CPU 30 a is “game control means” according to claim 3, and the liquid crystal panel 22 is claim 3. The “notification means” is configured.

  As shown in FIG. 7, in the slot machine 10 of the third embodiment, a stop order determining unit that determines the pressing order of the stop buttons 19a to 19c in which the winning combination of 0 sheets can be won. Means) 50 and a notice lottery section (notification lottery means according to claim 3) 51 for deciding whether or not to display (notify) the pressing order determined by the stop order decision section 50 on the liquid crystal panel 22. Is provided.

  The stop order determination unit 50 is activated when a winning combination of 0 sheets is won in a game in the RB introduction mode. The stop order determination unit 50 performs a stop order lottery, and determines the stop order of the first to third reels 14a to 14c in which the winning combination of 0 sheets can be won, that is, the pressing order of the stop buttons 19a to 19c. The pressing order of the stop buttons 19a to 19c is selected from six combinations. The result of the stop order lottery is fed back to the CPU 30a.

  The notification lottery unit 51 is operated after the stop order lottery is completed. The notification lottery unit 50 performs the notification lottery and determines whether or not the pressing order determined in the stop order lottery is displayed on the liquid crystal panel 22. When the notification lottery is won, the CPU 30a reads the graphic data corresponding to the pressing order displayed from the liquid crystal panel 22 from the ROM area of the memory 31, and displays the pressing order from the liquid crystal panel 22 based on the read graphic data.

  Next, the flow of the game in the third embodiment will be described with reference to FIG. 8, but since the game is performed in the normal mode in the same flow as in the first embodiment, the flow of the game in the normal mode will be described. The flow of the game after winning the BB mode will be described.

  When BB is won in the winning combination lottery and the player wins BB, the CPU 30a reads the execution program in the BB mode from the ROM area of the memory 31 and shifts from the normal mode to the BB mode.

  When winning a small combination or bonus combination in the BB mode, the CPU 30a writes the cumulative number of medals assigned to these winning combinations in the RAM area of the memory 31 and accumulates them. Thereby, the number of medals paid out to the player in the BB mode is managed.

  When shifting to the BB mode, a game in the RB introduction mode is first performed. In the RB introduction mode, the winning combination lottery is performed using the first normal table 40a. For this reason, in the RB introduction mode, the winning probability of the small role is the same as that in the normal mode. When the number of medals acquired by the player in the RB introduction mode reaches 465, the BB mode ends.

  When the winning combination of 0 sheets is won in the RB introduction mode, the CPU 30a operates the stop order determining unit 50. The stop order determination unit 50 performs stop order lottery. When the stop order lottery ends, the CPU 30a activates the notification lottery unit 51 to perform the notification lottery. When the information lottery is won, the pressing order of the stop buttons 19a to 19c determined by the stop order lottery is displayed from the liquid crystal panel 22. For this reason, if the player has won the notification lottery, the player can win a winning combination by pressing the stop buttons 19a to 19c in accordance with the pressing order displayed on the liquid crystal panel 22. When the stop buttons 19a to 19c are pressed so that the first to third reels 14a to 14c stop in the order determined by the stop order lottery, the CPU 30a and the reel drive controller 34 receive the winning symbol 15 for the winning winning line 15 The drawing-in control of the 0-piece winning symbol is performed so that they are aligned at the top.

  When the winning combination is 0, the CPU 30a reads the execution program in the RB mode from the ROM area of the memory 31, and shifts from the RB introduction mode to the RB mode. The 0 symbol combinations are arranged so that the 0 symbol combinations are located within the pull-in range. For this reason, if the stop buttons 19a to 19c are pressed according to the pressing order determined by the stop order lottery, the winning combination of 0 sheets is always won.

  If the stop button 19a to 19c is not pressed so that the winning combination of 0 sheets is won and the first to third reels 14a to 14c are stopped in the order determined by the stop order lottery, the CPU 30a and the reel drive controller 34 are pressed. Performs the kicking control of the 0-sheet winning symbol so that the 0-sheet winning symbol is not aligned on the winning effective line 15. In this case, the game in the RB introduction mode is continued.

  In the RB mode, the winning combination lottery is performed using the RB table. Therefore, in the RB mode, it is determined whether or not a bonus combination is won. The RB mode continues until the number of medals acquired by the player reaches 465. When the number of medals acquired by the player in the RB mode reaches 465, the BB mode ends.

  In the third embodiment, the RB mode is set as a special game. However, as a special game, for example, at least one of the first to third reels 14a to 14c is in a no-control state (no reel stop control is performed). , A challenge time (CT) mode in which the stop button is pressed according to the timing at which the stop button is pressed, a replay time (RT) mode in which the winning probability of replay is higher than the normal mode, and a high probability of transition to the RT mode. RT transition high probability mode, to notify the order of pressing the stop button, or to notify the symbols to be stopped on the winning effective line 15, by prompting the player to perform a specific winning combination, such as Assist time (AT) mode that allows you to win a prize, AT transition high probability mode that increases the transition probability to AT mode The stock time (ST) mode that stores the winning combination when it wins a specific winning combination, the high release probability mode that increases the release probability of the stored winning combination, and the bonus combination is drawn only for one game. An appropriate game mode may be set if the player has an advantage, such as a single bonus (SB) mode and a SB high probability mode in which the probability of transition to the SB mode is increased by a game of a certain section.

  In the third embodiment, the BB mode is shifted to the RB introduction mode and the RB mode once each. However, for example, the RB introduction mode and the RB mode may be shifted a plurality of times. In this case, the number-of-games lottery may be performed every time the RB introduction mode is started, and the termination condition of the RB mode may be set as appropriate. Further, for example, two types of BB modes configured by an RB introduction mode, an RB mode, and an RB introduction mode and a CT mode may be set, and which BB mode to shift to may be determined at the time of BB winning.

  In the third embodiment, the transition from the RB introduction mode to the RB mode is made with one winning combination of 0 sheets. However, for example, when the winning combination of 0 sheets is won continuously in 3 games (3 consecutive winnings). For example, a condition may be set after winning a winning combination of 0 sheets, such as shifting from the RB introduction mode to the RB mode. If 3 consecutive winnings of 0 sheets are used as the condition for transition to the RB mode, for example, if it is determined that the order of pressing the stop buttons 19a to 19c is notified continuously in 3 games, 3 games Can be performed continuously. Thereby, a player's expectation to RB mode can be raised.

  In the third embodiment, the first normal table 40a is used for lottery with a certain probability. However, a plurality of lottery tables having different winning probabilities for the zero-card combination are provided, for example, a transition to the BB mode is performed. You may vary the winning probability of the 0-piece combination, such as determining which lottery table to use each time.

  Next, a fourth embodiment will be described. In the fourth embodiment, when the number of games in the normal mode reaches the number of games determined by the number-of-games lottery, the game can be stopped. In stoppable games, the replay time (RT) symbol (the second special mode transition symbol according to claim 4) is the winning line when the number of medals inserted matches the number of coins determined by the number of coins inserted. 15 can be stopped. When the RT symbol stops on the winning winning line 15, the RT mode (second special mode according to claim 4) is entered. Note that the same reference numerals are used for functional units having the same functions as those in the first embodiment, and detailed descriptions thereof are omitted. In the fourth embodiment, the RT symbols are described as being arranged so that the RT symbols are located within the pull-in range. That is, description will be made assuming that there are four or less other symbols between RT symbols. In the fourth embodiment, the CPU 30 a and the reel drive controller 34 constitute “reel stop control means”.

  As shown in FIG. 9, in the slot machine 10 of the fourth embodiment, a game number determining unit (game number determining means according to claim 4) 60, a game number counting means (game number counting means according to claim 4). 61, an inserted number determining unit (an inserted number determining unit according to claim 4) 62 and a winning combination determining unit 63 are provided in the control unit 30.

  The game number determination unit 60 is activated when a game in the normal mode is started, for example, when the slot machine 10 is turned on, at the end of the BB mode, or at the end of the RT mode. In the game number determination unit 60, a game number lottery is performed. In the game number lottery, the number of games in the normal mode up to the stoppable game is determined. The result of the game number lottery is fed back to the CPU 30a.

  The game number counting unit 61 is activated after the game number lottery is performed. The number of games determined in the number-of-games lottery is set in the game number counting unit 61. The CPU 30a decrements the value of the game number counting unit 61 every time a game is started in the normal mode. Thereby, the number of games in the normal mode is counted.

  The inserted number determination unit 62 is activated when the number of games determined in the number-of-games lottery is performed. The inserted number determination unit 62 performs a drawing lottery to determine the number of inserted medals that can win a winning combination in a stoppable game.

  In the winning combination determining unit 63, the first normal table 40a, the second normal table 40b, and the RB table are provided in the same manner as the winning combination determining unit 40. The winning combination determining unit 63 is provided with an RT table 63a in addition to these tables. The RT table 63a is used in RT mode games. In the RT table 63a, the winning combination is assigned to the random value so that the replay winning probability is higher than that of the first normal table 40a and the second normal table 40b.

  Next, the flow of the game in the fourth embodiment will be described with reference to FIGS. 10 and 11. In the BB mode, the game is performed in the same flow as in the first embodiment. Description of the flow will be omitted, and the flow of the game in the normal mode and the RT mode will be described. In addition, since the game flow is the same as in the first embodiment before the transition to the stoppable game in the normal mode and when the number of medals inserted by the player and the number determined in the insertion lottery do not match, the explanation will be given. Omitted.

  As shown in FIG. 10, when a game in the normal mode is started, the game number determination unit 60 is operated, and a game number lottery is performed. The number of games determined by the number-of-games lottery is set in the game number counting unit 61. In the normal mode, first, three medals are inserted and a game is played. The CPU 30a decrements the number of games in the game number counting unit 61 every time a game is played. When the number of games in the normal mode reaches the number determined by the number-of-games lottery, the CPU 30a activates the inserted number determination unit 62.

  As shown in FIG. 11, the inserted number determination unit 62 performs a drawing lottery to determine the number of inserted medals that can win a winning combination in a stoppable game. Thereafter, the CPU 30a accepts the insertion of 1 to 3 medals. The player selects an arbitrary number of medals from 1 to 3, and inserts the selected number of medals. Then, the CPU 30a determines whether or not the number of inserted medals matches the number determined by the insertion lottery when the start lever 18 is pressed.

  When the numbers of the images match, the CPU 30a and the reel drive controller 34 perform RT symbol drawing control. If the numbers do not match, the CPU 30a and the reel drive controller 34 perform RT symbol kicking control. When the RT symbols are aligned on the winning line 15, the CPU 30 a reads the RT mode execution program from the ROM area of the memory 31 and shifts from the normal mode to the RT mode.

  When shifting to the RT mode, the CPU 30a inputs a table selection signal indicating the RT table 63a to the electronic lottery unit 39. Thereby, in the RT mode, the winning combination lottery is performed using the RT table 63a. In the RT mode, the replay winning probability is higher than in the normal mode, and the player can play a game while suppressing the consumption of medals.

  At the start of the RT mode, the upper limit number of times that the game in the RT mode can be performed is set in the game number counting unit 61. Each time a game is played in the RT mode, the number of games in the game number counting unit 61 is decremented. When the number of games in the game number counting unit 61 becomes “0”, the CPU 30a ends the RT mode and shifts to the normal mode.

  In the fourth embodiment, there is no difference in the winning probability of each inserted number in the inserting lottery. However, the winning probabilities may be different from each other. In this case, for example, each input number is set so that the ratio of selection of one sheet is 10%, the ratio of selection of two sheets is 30%, and the ratio of selection of three sheets is 60%. Set the probability of being selected. For example, when one player is inserted, the number of games in the RT mode is 300 times. When two players are inserted, the number of games in the RT mode is 100 times. When one player is inserted, the number of games in the RT mode is 30 times. Further, for example, when one player is inserted, the number of games determined by the game number lottery is 100 times (1/20) or 1000 times (19/20). When two players are inserted, the number of games determined by the game number lottery. Is 100 times (1/6) or 1000 times (5/6), and the number of games determined by the number-of-games lottery is 100 times (1/2) or 1000 times (1/2) when three cards are inserted. . In this way, if a difference is provided between the number of inserted coins, and the size of the privilege to be given and the probability that the privilege is given are made different, it is possible to increase a sense of tension when the player inserts a medal. Further, in this case, it is preferable to notify the liquid crystal panel 22 of the size of the privilege corresponding to each inserted number, the probability that the privilege is given, and the number of games up to the stoppable game.

  In the fourth embodiment, the RT mode is provided as the second special mode. However, as the second special mode, for example, the RT transition high probability mode in which the transition probability to the RT mode is high, the order of pressing the stop button is set. An assist time (AT) mode that allows a player to win a specific winning combination by encouraging the player to perform an operation associated with the game, such as notifying a symbol to be stopped on the winning line 15 or notifying, AT transition high probability mode in which the probability of transition to AT mode is high, stock time (ST) mode for storing a specific winning combination, and high probability release mode in which the stored winning combination has a high release probability The probability of transition to single bonus (SB) mode, in which bonus combinations are drawn only for one game, and SB mode are increased in games of a certain section Such as the B high probability mode, the player may set an appropriate game mode if the advantageous.

  Next, a fifth embodiment will be described. In the fifth embodiment, when the SB that is one of the winning combinations in the normal mode (“losing game winning combination” described in claim 5) is won and the SB wins, the SB mode (billing) is limited to one game. Move to “Loss Game” in Item 5. In the SB mode, it is determined whether or not the bonus combination is won. Note that the same reference numerals are used for functional units having the same functions as those in the first embodiment, and detailed descriptions thereof are omitted. In the fifth embodiment, the RT symbols are described as being arranged so that the RT symbols are positioned within the pull-in range. That is, description will be made assuming that there are four or less other symbols between RT symbols. In the fifth embodiment, the CPU 30a constitutes a “second table selection unit”.

  As shown in FIG. 12, in the slot machine 10 of the fifth embodiment, the winning combination determining unit 70 is provided in the control unit 30.

  The winning combination determination unit 70 is a first normal table 70a for determining a winning combination in a game in which three normal mode medals are inserted, and a second normal in which a winning combination is determined by a game in which one normal mode medal is inserted. Table 70b, SB table 70c for determining a winning combination in a game in SB mode, RB introduction table 70d for determining a winning combination in a game in RB introduction mode, and RB table (not shown) for determining a winning combination in a game in RB mode It has.

  In the first normal table 70a and the second normal table 70b, each of the random number values generated by the random number generator of the electronic lottery unit 39 is assigned any one of BB, small combination, replay, zero-sheet combination, SB, and loss. Yes. The first normal table 70a and the second normal table 70b are different in the number of random values to which the BB is assigned so that the BB winning probabilities are different from each other, whereby the second normal table 70b is changed to the first normal table 70a. The winning probability is set so that the winning probability of BB is higher than that. The winning probability of SB is set to 1 / 1.4, for example. For this reason, in the normal mode, most games win SB.

  In the SB table 70c, a bonus combination or a loss is assigned to a random value. Thereby, in the SB mode, it is determined whether or not a bonus combination is won. The winning probability of the bonus combination is set so that the payout rate in the SB mode is less than 100%. For this reason, a player becomes disadvantageous in SB mode.

  In the RB introduction table 70d, any one of a small combination, a replay, and a loss is assigned. In the RB introduction table 70d, a small combination is assigned to the same random number value as the first normal table 70a and the second normal table 70b. For this reason, the winning probability of the small role is the same in the normal mode and the RB introduction mode. Further, since no SB is assigned to the RB introduction table 70d, the payout rate is higher when the winning combination lottery is performed using the RB introduction table 70d than when the first normal table 70a and the second normal table 70b are used. Becomes higher.

  In the RB table, either a bonus combination or a loss is assigned. In the RB table, a bonus combination is assigned to most random numbers. That is, in the RB mode, the winning probability is set so that the bonus combination is won in most games. The payout rate is set so that the player is more advantageous in the RB mode game than in the normal mode by setting the bonus winning probability in this way.

  Next, the flow of the game in the fifth embodiment will be described with reference to FIG. 13. In the BB mode, the game is played in the same flow as in the first embodiment, so the description of the game flow in the BB mode. Will be omitted and the flow of the game in the normal mode will be described.

  As shown in FIG. 13, in the slot machine 10, first, three medals are inserted and a game in the normal mode is performed. In the winning combination determining unit 40, the random number value drawn by the electronic lottery unit 39 is checked against the first normal table 70a.

  When SB is won in the winning combination lottery and the stop buttons 19a to 19c are pressed, the stop control of the first to third reels 14a to 14c is performed so that the SB wins. Since the SB symbols constituting the SB are arranged so as to be located within the pull-in range, the SB wins regardless of the timing when the stop buttons 19a to 19c are pressed. When SB wins, the CPU 30a reads the SB mode execution program from the ROM area of the memory 31, and shifts from the normal mode to the SB mode. In the winning combination lottery in the SB mode, the SB table 70c is used to determine whether or not the bonus combination is won. The SB mode ends when a game is played once.

  When the winning combination lottery is won and the winning combination is won, the CPU 30a inputs a table selection signal indicating the second normal table 70b to the electronic lottery unit 39. In response to this, the electronic lottery unit 39 performs the winning combination lottery using the second normal table 70b in the next game. As a result, the winning probability of BB is increased in the game after winning the 0-piece combination. In subsequent games, the CPU 30a accepts only one medal. For this reason, the inserted second and subsequent medals are not detected by the medal selector and are returned to the player. As a result, in the game after winning 0 winning combination, the game is played by inserting one medal.

  When BB is won in the winning combination lottery and the player wins BB, the CPU 30a reads the execution program in the BB mode from the ROM area of the memory 31 and shifts from the normal mode to the BB mode.

  When winning a small combination or bonus combination in the BB mode, the CPU 30a writes the cumulative number of medals assigned to these winning combinations in the RAM area of the memory 31 and accumulates them. Thereby, the number of medals paid out to the player in the BB mode is managed.

  When shifting to the BB mode, a game in the RB introduction mode is first performed. In the RB introduction mode, the winning combination lottery is performed using the RB introduction table 70d. For this reason, in the RB introduction mode, the winning probability of the small role is the same as that in the normal mode. In the RB introduction mode, SB is not won, so the payout rate is higher than in the normal mode. For this reason, the RB introduction mode is more advantageous for the player even if the winning probability of the small role is the same in the normal mode and the RB introduction mode. Thereby, the normal mode can be lowered and the BB winning probability can be increased without changing the overall payout rate. When the number of medals acquired by the player in the RB introduction mode reaches 465, the BB mode is terminated before the RB mode is entered. When winning the replay in the RB introduction mode, the CPU 30a reads the execution program in the RB mode from the ROM area of the memory 31, and shifts from the RB introduction mode to the RB mode.

  In the RB mode, the winning combination lottery is performed using the RB table. Therefore, in the RB mode, it is determined whether or not a bonus combination is won. The RB mode continues until the number of medals acquired by the player reaches 465. When the number of medals acquired by the player in the RB mode reaches 465, the BB mode ends.

  Next, a sixth embodiment will be described. In the sixth embodiment, two types of game modes are set: a normal mode and a BB mode (“special mode” according to claim 1). The BB mode includes a CT mode (“general game” according to claim 1) and an RB mode (“special game” according to claim 1). If RB is won in CT mode, it will shift to RB mode. In a game other than the game won in the CT mode replay, the stop control of the first to third reels 14a to 14c is not performed (no control state), and the first game is performed according to the timing when the player presses the stop buttons 19a to 19c. The first to third reels 14a to 14c are stopped. In CT mode, the winning probability of replay is higher than in normal mode. Note that the same reference numerals are used for functional units having the same functions as those in the first embodiment, and detailed descriptions thereof are omitted. In the sixth embodiment, the replay symbols arranged on the first to third reels 14a to 14c are not located within the pull-in range, that is, five or more other symbols are arranged between the replay symbols. Explain that it is. Further, in the sixth embodiment, the CPU 30a constitutes “second table selection means” according to claim 6, and the CPU 30a and the reel drive controller 34 constitute “second reel stop control means” according to claim 6. Constitute.

  As shown in FIG. 14, in the slot machine 10 of the sixth embodiment, the winning combination determining unit 80 is provided in the control unit 30.

  The winning combination determination unit 80 includes a first normal table 40a, a second normal table 40b, and an RB table as in the first embodiment. In addition to these tables, the winning combination is determined by a CT mode game. Is provided.

  In the CT table 80a, RB, replay, or loss is assigned. In the CT table ("lottery table" according to claim 6) 80a, a first normal table ("lottery table" according to claim 6) 40a and a second normal table ("lottery table" according to claim 6) 40b. Are assigned to the same random value, but the number of random values to which replay is assigned is larger than that of the first normal table 40a and the second normal table 40b. Therefore, the normal mode and the CT mode have the same winning probability for the small role, and the CT mode has a higher replay winning probability than the normal mode. In the CT mode, for example, the winning probability of replay is set to 1 / 1.4, and it is preferable to set the winning probability so as to win the replay in most games.

  Next, the flow of the game in the sixth embodiment will be described with reference to FIG. 15. However, if the winning combination is 0, the game is performed in the same flow as in the first embodiment. The part from which a form and the flow of a game differ is demonstrated.

  As shown in FIG. 15, in the normal mode, the first normal table 40a or the second normal table 40b and the random number value lottery selected by the electronic lottery unit 39 are collated. When BB is won in the winning combination lottery in the normal mode and the player wins BB, the CPU 30a reads the execution program in the BB mode from the ROM area of the memory 31 and shifts from the normal mode to the BB mode.

  When the stop buttons 19a to 19c are pressed so that a small combination or bonus combination is won in the BB mode, the CPU 30a writes the cumulative number of medals assigned to the small combination in the RAM area of the memory 31 and accumulates it. Thereby, the number of medals paid out to the player in the BB mode is managed.

  In the CT mode, the CPU 30a inputs a table selection signal indicating the CT table 80a to the electronic lottery unit 39. Thus, in the CT mode, the winning combination lottery is performed using the CT table 80a. For this reason, the CT mode has the same winning probability for the small role as the normal mode. In CT mode, the winning probability of replay is higher than in normal mode.

  When winning a small combination or bonus combination in the BB mode, the CPU 30a writes the cumulative number of medals assigned to these winning combinations in the RAM area of the memory 31 and accumulates them. Thereby, the number of medals paid out to the player in the BB mode is managed. When the number of medals acquired by the player in the CT mode reaches 465, the BB mode ends before the transition to the RB mode.

  In the game in the CT mode, the game is performed under a non-control state in which the stop control of the first to third reels 14a to 14c is not performed except when the replay is won. For this reason, when the replay is not won in the CT mode, the small combination can be arbitrarily selected by pressing the stop buttons 19a to 19c when the small combination symbol is located on the winning effective line 15. Thus, a player with a higher skill than a beginner with a lower skill can increase the number of medals obtained each time a game is played in the CT mode.

  Further, when the replay is won, the replay cannot be won unless the stop buttons 19a to 19c are pressed when the replay symbol is located in the pull-in range (specific timing). That is, when the replay is won, the replay symbol pull-in control is performed when the stop buttons 19a to 19c are pressed when the replay symbol is within the pull-in range.

  In addition, when RB is won, the mode is changed from the CT mode to the RB mode. The RB mode continues until the number of medals acquired by the player reaches 465. When the number of medals acquired by the player in the RB mode reaches 465, the BB mode ends.

  Based on the above, if a player with high skill wins a replay with a game won in CT mode and wins a small role in a game not won with a replay, the medal can be reduced while suppressing the consumption of medals. It is possible to increase the number of acquisitions. Thereby, even if the upper limit is set for the number of medals to be paid out in the BB mode, the player can acquire more medals.

  Next, a seventh embodiment will be described. In the seventh embodiment, when the SB is won in the normal mode and the SB wins, the SB mode ("second special mode" described in claim 7) is entered only for the next game. In the SB mode of the seventh embodiment, the winning combination probability of the small role is higher than that in the normal mode. Note that the same reference numerals are used for functional units having the same functions as those in the first embodiment, and detailed descriptions thereof are omitted. In the seventh embodiment, the CPU 30a constitutes “game control means” and “second table selection means” according to claim 7.

  As shown in FIG. 16, in the slot machine 10 of the seventh embodiment, the winning combination determining unit 90 is provided in the control unit 30.

  The winning combination determining unit 90 includes a first normal table (a “lottery table” according to claim 7) 90a for determining a winning combination in a game in which three medals in the normal mode (first inserted number) are inserted, and the normal mode A second normal table (“lottery table” according to claim 7) 90b for determining a winning combination in a game in which one medal is inserted (second inserted number), and an SB for determining a winning combination in a game in SB mode The table 90c includes an RB table (not shown) for determining a winning combination in the RB mode game.

  The first normal table 90a and the second normal table 90b are a BB that grants the right to shift to the BB mode to each of the random number values generated by the random number generator of the electronic lottery unit 39, a small part with a medal payout, a replay, One of the 0 winning combination, SB, and lose is assigned. The first normal table 90a and the second normal table 90b are different in the number of random values to which the BB is assigned so that the BB winning probabilities are different from each other, whereby the second normal table 90b is the first normal table 90a. The winning probability is set so that the winning probability of BB is higher than that.

  In the SB table 90c, small roles, replays, and loses are assigned. As a result, in the SB mode, either the small role or the replay is won or the game is lost.

  In the RB table, either a bonus combination or a loss is assigned. In the RB table, a bonus combination is assigned to most random numbers. That is, in the RB mode, the winning probability is set so that the bonus combination is won in most games. The payout rate is set so that the player is more advantageous in the RB mode game than in the normal mode by setting the bonus winning probability in this way.

  Next, the flow of the game in the seventh embodiment will be described with reference to FIG. 17, but the game is played in the same flow as in the first embodiment in the BB mode, so the flow of the game in the BB mode is omitted. The flow of the game in the normal mode will be described.

  As shown in FIG. 17, in the slot machine 10, first, three medals are inserted and a game in the normal mode is performed. In the winning combination determination unit 40, the random value lottery selected by the electronic lottery unit 39 is checked against the first normal table 90a.

  When SB is won in the winning combination lottery and SB wins, the CPU 30a reads the SB mode execution program from the ROM area of the memory 31 and shifts from the normal mode to the SB mode. In the SB mode, the CPU 30a accepts only the insertion of two medals (the third inserted number), and the game is played with a bet of two medals. For this reason, the inserted third and subsequent medals are not detected by the medal selector and are returned to the player. When inserting a credited medal, the operation of the credit button is invalidated after the first medal is bet.

  In the winning combination lottery in the SB mode, the SB table 90c is used. The SB mode ends when a game is played once. When replay is won in the SB mode, the game is played with two bets even in the next game in the normal mode. In the game with two bets in the normal mode, the CPU 30 a inputs a table selection signal indicating the second normal table 90 b to the electronic lottery unit 39. In response to this, the random number value drawn by the electronic lottery unit 39 is checked against the second normal table 90b. For this reason, in the game with two bets in the normal mode, the winning probability of BB is higher than when the game is performed with three bets.

  The SB table 90c preferably has a higher replay win probability than the first normal table 90a. Thereby, since BB is drawn out with high winning probability after the SB mode, it is possible to increase the player's expectation for SB.

  When the winning combination lottery in the normal mode is won and the winning combination is won, the CPU 30a inputs a table selection signal indicating the second normal table 90b to the electronic lottery unit 39. In response to this, the electronic lottery unit 39 performs the winning combination lottery using the second normal table 90b in the next game. As a result, the winning probability of BB is increased in the game after winning the 0-piece combination. In the next game, the CPU 30a accepts only one medal. For this reason, the inserted second and subsequent medals are not detected by the medal selector and are returned to the player. As a result, in the game after winning 0 winning combination, the game is played by inserting one medal.

  When BB is won in the winning combination lottery and the player wins BB, the CPU 30a reads the execution program in the BB mode from the ROM area of the memory 31 and shifts from the normal mode to the BB mode. When shifting to the BB mode, a game in the RB introduction mode is first performed. When replay is won in the RB introduction mode, the CPU 30a reads the execution program in the RB mode from the ROM area of the memory 31, and shifts from the RB introduction mode to the RB mode. In either the RB introduction mode or the RB mode, the BB mode ends when the number of medals acquired by the player in the BB mode reaches 465.

  Conventionally, in a slot machine having a stock function, where the number of games until the BB is released is determined by lottery, the number of games from which the BB is released is determined in advance. In order to complete the game, one effect (continuous effect) is executed over a plurality of games, or a continuous effect including a game in which BB is released is executed. However, in slot machines that do not have a stock function (no stock function), it is reported that BB has won an internal prize by a combination of symbols (reach eyes) during a continuous performance, or a continuous performance. The player may perceive that the BB will be released at the time of the start of the game, or the BB will win during the continuous production. In some cases, the continuous performance was not executed until the end. However, in the seventh embodiment, if the SB is won in the normal mode and then the replay is won in the SB mode, the game in the normal mode (3 medal insertion) → the game in the SB mode (replay winning) → normal Since the game of mode (2 medals inserted) and a continuous production that is completed over 3 games are performed, and it is not possible to detect whether or not to win the BB until the continuous production is completed, to win the BB It is possible to maintain the player's sense of expectation and to increase the player's expectation for the production.

  Note that the present invention is not limited to a reel drive type slot machine, but can be equally applied to other gaming machines such as a slot machine using a liquid crystal panel or a pachinko machine in which a symbol is stopped and displayed by pressing a stop button. .
