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 order to win more medals in the BB mode, it is necessary to perform more games in the RB introduction mode while shifting to the RB mode a predetermined number of times.

  In a slot machine in recent years, a fixed number of medals can be obtained regardless of the player's skill in the RB mode. However, in the RB introduction mode, the number of medals obtained varies depending on the skill of the player. What has become mainstream. However, this sometimes caused an unfair feeling to beginners with low game skills.

For this reason, in Patent Document 1, when the number of medals acquired by the player during the BB mode does not reach the reference number, the winning probability of the small role after the end of the BB mode is greater than when the reference number is reached. This increases the number of medals obtained in the BB mode according to the skill of the player.
JP 2001-238999 A

  By the way, having the possibility of acquiring a large number of medals in a short period of time as described above will make the player have great interests, but will jealousize the player and impair the health of the game. It can also be a thing. For this reason, an upper limit is set for the number of medals to be paid out in, for example, the BB mode under the Customs Sales Act and voluntary regulations by slot machine manufacturers. It is considered to set the winning probability of a small role to be the same as that in the normal mode.

  However, if the winning combination probability of the small role in the RB introduction mode is the same as that in the normal mode, the number of medals that the player obtains does not change despite the transition to the BB mode, and the game becomes monotonous. It is possible. Moreover, since the number of inserted medals increases as the game in the RB introduction mode lasts for a long time, it is considered that the loss of medals acquired by the player increases if the number of medals paid out in the BB mode is constant. . For these reasons, the BB mode, which is a game for increasing the number of medals, is uninteresting and may cause the player to lose interest in the slot machine.

  In order to solve the above problems, the present invention can prevent a game from being uninteresting even if an upper limit is set for the number of game media to be paid out in a game in a special mode such as the BB mode. It is an object to provide a gaming machine, a program, and a recording medium.

  In order to achieve the above object, the gaming machine of the present invention includes a general game in which the winning probability of a small role to which a game medium is paid out is the same as that in the normal mode, and a special game in which the player has an advantage over the normal mode. Game control means for executing a game in the special mode and ending the special mode when a certain number of game media are paid out, and between the transition to the special mode and the end The number-of-games counting means for counting the number of games played in the general game, and the value of the privilege to be given to the player is determined according to the count value of the number-of-games counting means, and the special mode ends according to the result A privilege granting means for granting the privilege later is provided.

  The “privilege” indicates a state in which the player is advantageous, for example, a transition is made to a game mode in which the player is more advantageous than the normal mode, or a certain number of game media are paid out. As the game mode, for example, the probability of winning a replay (one of the winning roles) that can be played without the insertion of medals in a game that is followed by a game with the same number of bets as the game played in advance is usually Replay time (RT) mode that is higher than the mode, RT transition high probability mode that the probability of transition to the RT mode is high, the order of pressing the stop button, or the symbol that is stopped on the winning line is announced The assist time (AT) mode that allows a player to win a specific winning combination by prompting the player to perform an operation associated with the game, the AT transition high probability mode that increases the transition probability to the AT mode, the specific Stock time (ST) mode for storing the winning combination when winning the winning combination, high emission probability mode for increasing the release probability of the stored winning combination, Single bonus (SB) mode in which the particular winning combination is lottery only in the game, such as SB high probability mode to increase the transition probability to the SB mode in the game a certain interval, and the like.

  In this case, the “value” of the privilege indicates the size (amount) of the privilege given to the player. When the above game mode is used as the privilege, the number of times that the game can be performed in the game mode and the game mode The transition probability to shift to is determined according to the count value of the game number counting means. Further, the value of the privilege to be determined includes that the value of the privilege is “0”, that is, that no privilege is given.

  In addition, the count value is divided into a plurality of groups by dividing the count value into a predetermined range, and a plurality of privilege grant determination tables having different privilege values from each other are provided so as to correspond to the respective groups, and the privilege grant means It is preferable to perform lottery using a privilege grant determination table corresponding to the group to which the count value belongs to determine the value of the privilege.

  The game machine program of the present invention is a special mode consisting of a general game having the same winning probability as a normal mode in which a game medium is paid out and a special game in which the player has an advantage over the normal mode. The game control means for ending the special mode when a certain number of game media are paid out, and the general game between the transition to the special mode and the end. The number-of-games counting means for counting the number of games played, and the value of the privilege to be given to the player is determined according to the count value of the number-of-games counting means. The computer of the gaming machine is made to function as a privilege granting means for granting a bonus.

  In addition, the recording medium of the present invention is capable of playing a game in a special mode consisting of a general game having the same winning probability as a normal mode in which a game medium is paid out and a special game in which the player has an advantage over the normal mode. A game control means for executing and ending the special mode when a certain number of game media have been paid out, and being played in the general game between the transition to the special mode and the end The number-of-games counting means for counting the number of games and the value of the privilege to be given to the player are determined according to the count value of the number-of-games counting means, and according to the result, the privilege is given after the end of the special mode The computer-readable recording medium stores a program that causes the computer of the gaming machine to function as a privilege granting means.

  According to the present invention, since the value of the privilege granted after the end of the special mode is determined according to the number of games performed in the general game of the special mode, it is possible to eliminate the monotony of the general game, and When the special mode is terminated when the winning probability of the regular game small role is the same as the normal mode and a certain number of game media are paid out, the general game compensates the player's loss for a long period of time Can make it possible. Thereby, even if an upper limit is set for the number of game media to be paid out in the game in the special mode, it is possible to prevent the game from being uninteresting.

  In addition, since the privilege granting means performs lottery using the privilege grant determination table corresponding to the group to which the number of games played in general games belongs, and determines the value of the privilege, the value of the privilege according to the development of the game The game can be changed, and a new game can be given to the general game, and a game with a sense of tension can be played in the general game.

  FIG. 1 shows an appearance of the slot machine 10, and first, an outline of a game flow of the slot machine 10 will be described. In the slot machine 10 shown in FIG. 1, three types of game modes are set: a normal mode, a BB mode (special mode), and a replay time (RT) mode. When the BB that gives the right to shift to the BB mode is won by the winning combination lottery in the normal mode and BB is won, the mode is switched from the normal mode to the BB mode. The BB mode ends when the number of medals paid out reaches a specified number (for example, a maximum of 465).

  In the BB mode, an RB mode in which it is determined whether or not to win a predetermined winning combination (which is not won in the normal mode) and an RB introduction mode in which whether or not to shift to the RB mode is determined by lottery ( General game).

  In the RB mode, a game is played by betting one medal, and the winning probability is set so that a specific winning 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. The RB mode ends when 12 games are played or the specific winning combination wins 8 times. 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. And if RB is won in RB introduction mode, it will transfer to RB mode from the next game. The RB introduction mode and the RB mode are repeatedly shifted until the number of medals paid out in the BB mode reaches a specified number.

  The RT mode is shifted to an RT lottery performed after the end of the BB mode. In RT mode, the winning probability of replay is higher than in normal mode. In the RT lottery, the number of games (number of games) in the RT mode is also determined at the same time, and when the number of games determined in the RT lottery is consumed, the RT mode ends.

  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 pressing 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.

  As shown in FIG. 2, the operation of the slot machine 10 is basically controlled by a control unit 30 including a CPU (game control means) 30 a and a memory 31. In addition to the CPU 30a and the memory 31, the control unit 30 constitutes a privilege granting means together with an electronic lottery unit 39, a winning combination determining unit 40, a game number counting unit 41 that counts the number of games in the RB introduction mode, and the CPU 30a. An RT lottery unit 42 for performing RT lottery is provided.

  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 first to third reels 14a to 14c are attached to the drive shafts of the stepping motors 35a to 35c, respectively. And control of the 1st-3rd reels 14a-14c is performed by controlling the drive of each stepping motor 35a-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 determination unit 40 includes a normal winning combination lottery table for determining a winning combination in the normal mode and the RB introduction mode, an RB winning combination lottery table for determining a winning combination in the RB mode, and an RT for determining the winning combination in the RT mode. It has a winning lottery table.

  The normal winning combination lottery table includes a BB that grants the right to shift to the BB mode for each random number generated by the random number generator of the electronic lottery unit 39, a small part with a medal payout, and a replay (RB in the RB introduction mode). ), One of the losers is assigned. Multiple types of small roles are set so that the number of medals paid out is different.

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

  In the RT winning combination lottery table, the same winning combination as the normal winning combination lottery table is assigned, but the number of random values to which replay is assigned is larger than that in the normal table. For this reason, the winning probability of replay is higher in the RT mode than in the normal mode.

  In the winning combination determination unit 40, the random value lottery by the electronic lottery unit 39 is selected from the normal winning combination lottery table, the RB winning combination lottery table, and the RT winning combination lottery table depending on the game mode being transferred. Is matched. Thereby, a winning combination or a loss is determined. The normal winning combination lottery table is used in the normal mode and the RB introduction mode, but 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. In addition, when replay is won in the RB introduction mode, it is considered that RB has been won. In addition, as a winning combination lottery table used in the normal mode, in addition to the normal winning combination lottery table, a second normal winning combination lottery table used in a state where BB has won an internal prize may be provided. Then, only the small combination, replay, and loss are assigned to the second normal winning combination lottery table. In this case, the normal winning combination lottery table is used when BB has not won an internal prize, and the second normal winning combination lottery table is used when BB has won an internal prize. Thereby, it is possible to prevent the BB from being won in the normal mode.

  The game number counting unit 41 is operated in the RB introduction mode. The CPU 30a counts up the count value of the game number counting unit 41 every time a start signal is input. Thereby, the number of games in the RB introduction mode is counted. When the RB introduction mode ends, the count value is reset. At the same time, the CPU 30 a writes the count value of the game number counting unit 41 in the RAM area of the memory 31.

  The RT lottery unit 42 is activated after the BB mode is finished. The RT lottery unit 42 performs an RT lottery. The RT lottery is one of a first RT table (privilege determination table) 43, a second RT table (privilege determination table) 44, a third RT table (privilege determination table) 45, and a fourth RT table (privilege determination table) 46. It is done using. The table used in the RT lottery is selected according to the count value written in the memory 31.

  In the first to fourth RT tables 43 to 46, the winning or losing is assigned to the random number value to be collated, and the number of games in the RT mode is assigned to the random value to which the winning is assigned. Thereby, in the RT lottery, whether or not to shift to the RT mode is determined, and the number of games in the RT mode is determined. Each table is different in at least one of the RT lottery winning probability and the range of the number of games to be selected.

For example, the first RT table 43 has an RT lottery win probability of 1/100, the range of games selected is 1 to 50 times, and the second RT table 44 has an RT lottery win probability of 1/10 and the number of games selected The range is 1 to 50 times, the third RT table 45 has an RT lottery win probability of 1/100, the number of games selected is 50 to 100 times, the fourth RT table 46 has an RT lottery win probability of 1/10, The range of the number of games to be selected is 50 to 100 times. In other words, the winning probability of the RT lottery and the range of the number of games to be selected are set so that the relative relationship between the tables is as follows.
First RT table 43 → “It is difficult to enter RT mode and the number of games is small”
Second RT table 44 → “Easy to enter RT mode and few games”
3rd RT table 45 → “It is difficult to enter RT mode and there are many games”
4th RT table 46-> “Easy to enter RT mode and many games”

  Note that the winning probability of the RT lottery and the range of the number of games to be selected may be set as appropriate. Further, the number of games to be selected may be set for each table without being set for every certain range.

  The hopper device 47 pays out a prescribed number of medals to the medal tray 20 when winning a small role or adds the prescribed 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 47.

  Next, the operation of the slot machine configured as described above will be described. As shown in FIG. 3, in the slot machine 10, a game in the normal mode is first performed. When 1-3 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 value lottery by the electronic lottery unit 39 is checked against the normal table.

  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 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 specific winning combination in the BB mode, the CPU 30a writes the number of medals to be paid out to the player when these are won in the RAM area of the memory 31 and accumulates them. Thereby, the number of medals paid out in the BB mode is managed.

  In the BB mode, a game is first played in the RB introduction mode. When the CPU 30a shifts to the RB introduction mode, the game number counting unit 41 is operated. The CPU 30a increments the count value of the game number counting unit 41 every time a game is played in the RB introduction mode. In the RB introduction mode, the winning combination lottery is performed using the normal table as in the normal mode. 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 CPU 30a recognizes that the number of medals acquired by the player reaches a specified number when winning a small role in the RB introduction mode, the CPU 30a controls the hopper device 47 so that the number of medals paid out to the player becomes the specified number. Control to end the BB mode. When the BB mode ends, the normal mode is resumed. Further, when the RB is won before the number of medals paid out to the player in the RB introduction mode reaches the specified number, the CPU 30a reads the RB mode execution program from the ROM area of the memory 31, and from the RB introduction mode to the RB Switch to mode.

  At the end of the RB introduction mode, the CPU 30a writes the count value of the game number counting unit 41 to the RAM area of the memory 31 and resets the count value of the game number counting unit 41. In the RB mode, the winning combination lottery is performed using the RB table. The RB mode ends when the game is played 12 times or the specific winning combination wins 8 times. When the number of medals acquired by the player during the RB mode reaches a specified number, the BB mode is terminated. Further, when the RB mode is finished without the number of medals acquired by the player reaching the specified number, the mode is again switched to the RB introduction mode. When the BB mode ends, the RT lottery unit 42 performs RT lottery. When the RT lottery is won, the CPU 30a reads the RT mode execution program from the ROM area of the memory 31 and shifts to the RT mode.

  As shown in FIG. 4, in the RT lottery, the CPU 30a reads the count value written in the RAM area of the memory 31, and the count value is a value belonging to any of a plurality of groups separated by a predetermined range. The table used for the RT lottery is selected from any of the first to fourth RT tables depending on whether there is any.

  When the number of games in the RB introduction mode is 10 times or less (group A), the CPU 30a inputs a table selection signal indicating the first RT table 43 to the RT lottery unit 42. In response to this, the RT lottery unit 42 performs RT lottery using the first RT table 43.

  When the number of games in the RB introduction mode is 11 to 20 times (group B), the CPU 30a inputs a table selection signal indicating the second RT table 44 to the RT lottery unit 42. In response to this, the RT lottery unit 42 performs the RT lottery using the second RT table 44.

  When the number of games in the RB introduction mode is 21 to 30 (group C), the CPU 30a inputs a table selection signal indicating the third RT table 45 to the RT lottery unit 42. In response to this, the RT lottery unit 42 performs the RT lottery using the third RT table 45.

  When the number of games in the RB introduction mode is 31 times or more (group D), the CPU 30a inputs a table selection signal indicating the fourth RT table 45 to the RT lottery unit 42. In response to this, the RT lottery unit 42 performs the RT lottery using the fourth RT table 45.

  As described above, in the present embodiment, since the number of games in the RB introduction mode increases and the number of games in the RT mode is easily increased and the number of games in the RT mode is likely to increase. , It is possible to play a game in the hope that the player won the replay in the RB introduction mode and does not shift to the RB mode. Thereby, even if an upper limit is set for the number of medals to be paid out in the BB mode, the player can have a new interest.

  FIG. 5 shows an example in which a recording medium (CD, flexible disk, IC memory, MO, etc.) 60 is installed in the slot machine 10, and the recording medium 60 has means as shown in the flowcharts of FIGS. A program to be realized by the computer 61 including the CPU 30a and the memory 31 is stored. In this case, for example, a game in a special mode consisting of a general game with the same winning probability as a normal mode in which a game medium is paid out and a special game in which the player has an advantage over the normal mode is executed and is constant. Game control means for ending the special mode when a number of game media are paid out, and counting the number of games played in the general game between the transition to the special mode and the end A computer as a privilege granting means for determining the value of the number of games to be played and the value of the privilege to be given to the player according to the count value of the number of game counts and granting the privilege after the end of the special mode according to the result A program for causing 61 to function is recorded in the recording medium 60. Then, the recording medium 60 is loaded into the reading device 62 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 60. 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 60 in a personal computer and play a slot machine game on a monitor.

  In the above embodiment, the RB mode is continued until the specified number of medals are paid out when the mode is changed to the RB mode in the BB mode. However, the RB mode has been played a specified number of times or a specified number of wins have been won. The mode of the BB mode may be appropriately set such that the process is terminated on the condition that it has occurred and the mode can be shifted to the RB mode a plurality of times during the BB mode.

  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. .

It is an external view of the slot machine using the present invention. FIG. 2 is a functional block diagram showing an electrical schematic configuration of the slot machine shown in FIG. 1. It is a flowchart which shows the flow of the whole game. It is a flowchart which shows the flow of selection of the 1st-4th table in RT lottery. FIG. 26 is an explanatory diagram when a recording medium storing a program is installed in a slot machine.
