The operation unit 30 is also provided with a settlement switch (not shown), a stored medal display unit (not shown), which is an example of a display unit, and the like. This stored medal display section is configured to be able to display, in addition to the number of stored medals, that the later-described game section is an advantageous section.

Further, as shown in FIG. 2, the slot machine 1 includes a control device 100 that controls the entire slot machine 1, a rotating reel unit 40, a rotating reel position detection sensor 44, and a hopper unit 50 that pays out medals. . The control device 100, the rotating reel unit 40, the rotating reel position detection sensor 44, and the hopper unit 50 are a power supply (not shown) that turns on/off the main power of the slot machine 1, and change the setting values of the slot machine 1. It is arranged inside the housing 10 together with a setting unit 45 and the like operated by the administrator when performing the operation.

The rotating reel unit 40 is arranged substantially in the center inside the housing 10, and drives a plurality of rotating reels (three rotating reels 41, 42, 43 in this embodiment) and the rotating reels 41, 42, 43. It is composed of stepping motors 61 , 62 and 63 . Each of the rotating reels 41, 42, 43 has a substantially cylindrical shape, and as shown in FIG. Symbols and reference points (not shown) are provided. The reference point is arranged, for example, at the center of the zero-numbered pattern (bell A) on the reels 41, 42, and 43. As shown in FIG.

Here, an outline of the game played on the slot machine 1 will be described with reference to FIGS. 1 to 9. FIG.

As shown in FIG. 1, when a game is played on the slot machine 1, first, medals are inserted from the medal slot 31, or accumulated medals (that is, credits) are used by operating the bet switch 32. to bet medals. When a predetermined number of medals (for example, 1 to 3) are betted, the activated line is activated and the start switch 33 can be operated, that is, the game can be started. Become. At this time, the medals inserted in excess of the prescribed number set according to the gaming state or the like are accumulated as credits.

As shown in FIG. 4, the effective line is a virtual line for determining the winning of a winning combination. connected one by one. In this slot machine 1, the activated line is composed of, for example, a downward-sloping line 70, and is activated by betting a predetermined number of medals (for example, three). As an example, the symbols displayed on the display window 21 of the slot machine 1 are three symbols for each rotating reel.

When the start switch 33 is operated in a state where the game can be started, a lottery (hereinafter referred to as an internal lottery) is conducted by an electronic computer within the slot machine 1, and the reels 41, 42 and 43 are rotated. be started. In this state, when one of the stop switches 34, 35, 36 is operated, the rotating reels 41, 42, 43 corresponding to the operated stop switch 34, 35, 36 are stopped and the display window 21 is hit. Results are displayed according to the role played. When all the rotating reels 41, 42, 43 are stopped, a predetermined number of medals are paid out according to the winning combination, and one game ends. In this embodiment, when all the rotating reels 41, 42, 43 are stopped and a combination of symbols set for each winning combination by internal lottery is arranged on the pay line 70, the pay line 70 is displayed. It is determined that the combination corresponding to the combination of symbols arranged above has won. It should be noted that the case where the combination of symbols corresponding to the winning combination does not stop on the activated line 70 (so-called loss) is also included in winning.

Thus, a series of actions to obtain a game result by operating the bet switch 32, the start switch 33 and the stop switches 34, 35, 36 is called a game. The game unit is a game, and one game is called a unit game.

Also, during the game, one game section is set out of a plurality of game sections, and one game state is set out of a plurality of game states. Then, an internal lottery is performed based on the set game section and game state. The game state includes a first game state, a second game state and a third game state, as shown in FIGS.

The first gaming state is a gaming state for determining the type of replay combination (see FIG. 9) and the winning probability thereof among the combinations to be won by the internal lottery (hereinafter simply referred to as "winning combination"). As shown in FIG. 5, it consists of RT0 and RT1.

RT0 is set when the second game state transitions from the special combination execution state to the special combination non-carried over state, or when the game state is initialized (for example, when the RAM is cleared) (that is, when the first game state is transition from RT1 to RT0). Also, the first game state immediately after the slot machine 1 is installed in a store or the like is also set to RT0. In other words, the first gaming state is all set to RT0, except when the type BB is being executed.

RT1 is set when the second game state shifts from the special combination non-carry-over state to the special combination execution state (that is, the first game state shifts from RT0 to RT1). In RT1, as shown in FIG. 9, there is no possibility of winning a replay hand and a kind of BB. Also, in RT1, the section transition lottery and the AT lottery, which will be described later, are not performed.

The second game state includes a special role non-carried-over state in which the winning of the first-class BB won by the internal lottery is not carried over, a special role-carried-over state in which the winning of the first-class BB won by the internal lottery is carried over, and a winning one. and a special role execution state for executing BB.

The special role non-carry-over state is when the number of paid out medals exceeds a predetermined number (eg, 180 or 2) after transitioning to the special role implementation state, or when the gaming state is initialized (eg, RAM clear It is set when a predetermined condition such as (time) is satisfied.

The special handover state is set when a type BB is won by an internal lottery and predetermined conditions to be described later are satisfied. The type BB is a type continuous operation device (so-called big bonus) relating to a type of special type, and is an example of a type of special type. If the type BB is carried over, the lottery for the type BB is not performed. Further, the carried over type BB flag is configured not to disappear even if the set value is changed, but it may be configured to disappear.

The special role implementation state is set when a special role is won and won by internal lottery, and a kind of BB implementation state (indicated by BB general in FIG. 6) and RB carryover state (in FIG. 6, JAC inside ) and RB implementation state (shown in JAC in FIG. 6). BB general is set when a special role wins. General BB is an example of a non-internal state of the prize, and is set when the RB (JAC1 to 4 in FIG. 9), which is an example of a special prize, is not won by an internal lottery. The inside of the JAC is an example of the internal state of the accessory, and when the second game state is the type BB execution state BB general, RB (that is, JAC 1 to 4 in FIG. 9) is won by internal lottery and RB wins. set if not During JAC is an example of a state in which the prize is executed, and is set when the winning RB wins a prize. During JAC, after completing 12 games from the time of transition to JAC, or by winning 8 times in some role during JAC, transition to BB general.

The third game state is a state for determining effects to be performed during a game, and as an example, as shown in FIG. 7, it is composed of a normal game state and an AT.

The normal game state is a state in which no instruction function occurs, and is set, for example, after changing the set value, after clearing the RAM, after the end of the AT, and until the AT lottery is won. The slot machine 1 has, as general game states, a normal state and a high-probability state in which the probability of winning the AT lottery is higher than in the normal state (in other words, AT is more likely to be awarded than in the normal state). A high-probability state, for example, is configured such that an indication function can occur temporarily, but occurs less frequently than AT. For example, the AT lottery is performed according to the winning combination won by the internal lottery when the first game state is RT0 and the game section is the advantageous section. The transition from the normal state to the high probability state is performed, for example, when the internal lottery is performed when the first game state is RT0 and the game section is the advantageous section, and as a result, the AT lottery is not won. It is done by winning a high-probability state transition lottery.

AT is a state in which an instruction function is generated, and is set until the number of games that have elapsed since the third game state shifted to AT reaches a period in which AT can be played. In the AT, the pushing order of the pushing order with the payout of medals is notified, and the expected value of obtaining medals is higher than that in the normal game state (for example, normal state).

The AT is an example of a special game state that is more advantageous to the player than the normal state, and the AT lottery is an example of a special game state lottery. In addition, the AT extension lottery may be included in the special game state lottery.

The game section is a state for determining whether or not the processing related to the instruction function is to be performed, and as an example, as shown in FIG. 8, it is composed of an advantageous section and a normal section.

The advantageous section is a section in which processing related to the instruction function and lottery can be executed, and the advantageous section ends after the game section wins the section transition lottery based on the results of the internal lottery performed in the normal section. It is set until the condition is met. The advantageous section includes an advantageous section in which the third game state progresses in the normal game state and an advantageous section in which the third game state progresses in the special game state (that is, AT).

The normal section is a section in which processing related to the instruction function and drawing cannot be executed, and is set when an advantageous section is not set as a game section. In the normal section, the third game state progresses in the general game state.

Note that the instruction function is a function that teaches the player the operation procedure (for example, the order of pushing the winning combination) or the operation method that affects the ball output. and/or the positions of the rotating reels 41, 42, and 43 when the stop switches 34, 35, and 36 are operated. is a predetermined operating position, the function of instructing the operating position of a winning combination. That is, AT is set as the third game state only when the game section is the advantageous section.

Next, the control device 100 is described. The control device 100 is composed of a main control section 110 and a sub-control section 120, as shown in FIG.

Each of the main control unit 110 and the sub-control unit 120 includes a CPU that performs calculations and the like, and a storage device (for example, ROM and RAM) that stores programs or data necessary for the progress of a game. The main control unit 110 includes an internal lottery unit 111, a rotating reel control unit 112, a game result determination unit 113, a section control unit 114, a game state control unit 115, a measurement unit 116, and a set value control unit 117. and controls the progress of the game. The sub control unit 120 has an effect control unit 121 and performs control for performing various effects and the like.

Each unit of the main control unit 110 and the sub-control unit 120 described below is a function realized by executing a predetermined program by the CPU, for example.

The internal lottery section 111 has a plurality of internal lottery tables, and conducts an internal lottery upon reception of the operation of the start switch 33 . Specifically, the internal lottery section 111 determines the first game state (in other words, RT state) when the operation of the start switch 33 is accepted, and selects an internal lottery table based on the determined RT state. Then, the internal lottery section 111 conducts an internal lottery based on the selected internal lottery table and the random number obtained when the operation of the start switch 33 is accepted.

For example, the winning combination is determined based on the internal lottery table shown in FIG. This internal lottery table is provided for each RT state, and has information on winning areas that may be won by the internal lottery. At least one winning combination associated with a combination of symbols is set in the winning area.

In FIG. 9, for each of the RT state and the second game state, the winning areas with the possibility of winning are indicated by "O", and the winning areas with no possibility of winning are indicated by "X". That is, each internal lottery table is provided with a plurality of areas (numerical area) in which wins corresponding to random numbers obtained when the start switch 33 is operated are stored. are associated with the winning areas indicated by "O" in FIG.

The slot machine 1 has an operation mode combination in which the number of medals to be paid out changes based on the operation mode as a combination for winning the internal lottery. In this embodiment, the operation modes include a first operation mode in which the stop switches 34, 35, and 36 are operated in a predetermined operation order, and an operation mode in which the stop switches 34, 35, and 36 are operated in an operation order different from the first operation mode. and a second mode of operation. The operation mode combination is configured such that the number of medals to be paid out according to the second operation mode is smaller than the number of medals to be paid out based on the first operation mode.

As an example, the operation mode combination includes a first combination and a second combination that is won at the same time as the first combination and that pays out fewer medals than the first combination. The first prize is won by operating the stop switches 34, 35, 36 in the first operation mode, and the second prize is won by operating the stop switches 34, 35, 36 in the second operation mode different from the first operation mode. Earn prizes by operating.

More specifically, as shown in FIG. 9, the slot machine 1 has "left bell", "middle/left/right bell", "middle/right/left bell", "right/right bell" as an example of the first combination. It has respective pressing order roles of "left/middle bell" and "right/middle/left bell", and examples of the second role include "left one role", "middle/left/right one role", and "middle role".・There are pushing orders of "Right/Left 1-card", "Right/Left/Center 1-card" and "Right/Center/Left 1-card". When each pressing order "Bell" is hit, at the same time, the pressing order "1 piece role" different from each pressing order "Bell" is hit. In other words, when the stop switches 34, 35 and 36 are operated in the first operation mode according to the push order set for each push order "Bell", eight medals are paid out "Bell". wins. On the other hand, when the stop switches 34, 35, and 36 are operated in an order different from the order of operation set for each pressing order, in other words, in the second operation mode, one medal is paid out. role" will be awarded.

For each pushing order combination shown in FIG. 9, the set pushing order is described immediately before "Bell" or "One-piece combination". For example, in the case of "left bell", the order of the left stop switch 34, the middle stop switch 35 and the right stop switch 36, or the order of the left stop switch 34, the right stop switch 36 and the middle stop switch 35 By operating it, "Bell" wins a prize. Further, for example, in the case of the "middle/right/left single hand", the "single hand" is won by operating the middle stop switch 35, the right stop switch 36 and the left stop switch 34 in this order.

The operation mode is not limited to the pressing order of the stop switches 34, 35, and 36, and may be the operating timing of the stop switches 34, 35, and 36. may be a combination of

The reel control unit 112 controls the stepping motors 61, 62, 63 of the reel unit 40 in accordance with reception of the operation of the start switch 33 or the stop switches 34, 35, 36, and Starts or stops the rotation of 43 (that is, controls the rotation of reels 41, 42, 43).

For example, when the start switch 33 is operated while all the reels 41, 42 and 43 are stopped, the reel control section 112 rotates all the reels 41, 42 and 43. When any one of the reels 41, 42, 43 is rotating and the stop switches 34, 35, 36 corresponding to the rotating reels 41, 42, 43 are operated, the reel control unit 112 , the reels 41, 42, 43 corresponding to the operated stop switches 34, 35, 36 are stopped.

When stopping the reels 41, 42, 43, the reel control unit 112 determines the combination won by the internal lottery and the timing at which each stop switch 34, 35, 36 is operated (that is, each stop switch 34, 35 , 36 are received, the position of the corresponding reels 41, 42, and 43), pull-in control or kick-off control is performed. The pull-in control is a control to stop the rotation of each of the rotary reels 41, 42, 43 so as to pull the symbol corresponding to the winning combination onto the pay line 70. FIG. Kicking control is control to stop the rotation of the rotary reels 41 , 42 , 43 so that the symbols corresponding to the winning combination are not aligned on the pay line 70 .

The game result determination unit 113 determines the game result based on the result of the internal lottery and the result of the stop control of the rotating reels 41 , 42 and 43 . The result of the game includes, for example, determination of whether or not the winning combination is won based on the symbols arranged on the pay line.

The game result determination unit 113 controls the hopper unit 50 and pays out medals based on the determined game result or reception of the operation of the settlement switch. The medals paid out based on the result of the game (that is, the medals obtained by winning a role or winning a prize) are first accumulated as credits. As a result of accumulating medals, when the upper limit of credits (for example, 50) is exceeded, the medals exceeding the upper limit are paid out from the hopper unit 50 . Also, when there are one or more stored medals (that is, when the credit is one or more) and the payment switch is operated, the stored medals are paid out from the hopper unit 50 .

For example, when the third gaming state shifts to AT, the game result determination unit 113 outputs a signal indicating that the third gaming state has shifted to AT to the hall computer to notify the administrator.

The zone control unit 114 sets a game zone from among a plurality of game zones (normal zones and advantageous zones in this embodiment).

Specifically, when the game section is a normal section, the section control unit 114 performs section transition lottery, which is a lottery to determine whether the game section remains the normal section or an advantageous section is given, A game section is set as an advantageous section when the section transition lottery is won. Whether the section transition lottery is successful or not is determined, for example, by whether or not the player wins the internal lottery for the winning combination for which the section transition lottery is performed (that is, the lottery target combination).

In the section transition lottery, the winning probability may be varied depending on the setting value of the slot machine 1, or may not be provided. When providing a difference in the winning probability of the section transition lottery, for example, it may be realized by providing a set difference in the winning probability in the internal lottery of the lottery target role, or it is performed when the lottery target role is won by the internal lottery. It may be realized by providing a set difference in the winning probability of the lottery.

The section control unit 114 controls a normal section in which the game progresses in a normal game state, and a section in which the process related to the instruction function and the lottery can be executed. One game section for which an internal lottery is performed can be provided from a plurality of game sections including an advantageous section in which the game progresses in a normal game state or a special game state.

In this embodiment, when the game section is an advantageous section, the section control unit 114 determines whether to keep the game section as an advantageous section or to give a normal section. For example, the section control unit 114 gives a normal section when the game section is an advantageous section and a predetermined end condition is satisfied. The end condition is, for example, when the number of games (that is, the number of games played in the advantageous section) that has elapsed since the game section measured by the measuring unit 116 was set as the advantageous section reaches a predetermined value (for example, 1500 games). Alternatively, it is satisfied when the difference number of medals after the game section is set to the advantageous section reaches a predetermined value (for example, 2400). The medal difference number (in other words, the medal payout difference number) is the sum of the difference between the number of bet medals and the number of payout medals.

When the game section shifts to the advantageous section, the section control unit 114 activates the instruction function during the advantageous section and activates the character (ie, RB or CT) and the character continuously actuating device (ie, type BB). Only when the average ball payout rate exceeds 100% when the game is advanced so as to win the maximum number of payouts of small wins except the above, it is indicated that it is an advantageous section via a display part provided in the operation part 30. - 特許庁display.

The game state control unit 115 controls transitions among the first game state, the second game state, and the third game state.

For example, the gaming state control unit 115 sets one RT state in which internal lottery is performed from among a plurality of RT states (RT0 and RT1 in this embodiment). Specifically, as described above, the gaming state control unit 115 sets the first gaming state to RT0 when the second gaming state shifts to the special combination non-carried over state, and the second gaming state changes to the special combination execution state. , the first game state is set to RT1.

In addition, the game state control unit 115 shifts the game state to a special game state that is more advantageous to the player than the normal state when a preset lottery condition (hereinafter simply referred to as a lottery condition) is satisfied. Perform a special game state lottery as to whether or not. As described above, the special game state lottery includes the AT lottery, the high-probability state transition lottery, and the AT or high-probability state extension lottery. The lottery conditions are set in advance according to the special game state to be shifted. For example, an AT lottery is performed when a predetermined winning combination (for example, a so-called rare winning combination of cherry, watermelon, etc.) is won by an internal lottery. Further, for example, the high-probability state transition lottery is performed when the first game state is RT0 and the game section is an advantageous section, and a rare combination is won by the internal lottery, but the AT lottery is not won.

As shown in FIG. 2, the game state control section 115 has a highly-probable number-of-games provision section 1151 and a period extension section 1152 .

The high-probability game number provision unit 1151 is configured to be capable of providing a high-probability game number, which is the number of games that can be played in a high probability state.

For example, the high-precision number-of-games provision unit 1151 provides a high-precision number of games at an arbitrary timing when the following conditions are satisfied. The number of high-precision games given at one time is one game or more, and for example, it is possible to configure so that the degree of expectation of the number of high-precision games given is different according to the set value.
・If you win the high-probability state transition lottery when the third game state is "normal state".
・If you win the extended lottery in the high probability state when the third game state is the “high probability state”.
・When the third game state is "AT" and the extended lottery in the high probability state is won. "AT" can include pseudo-bonuses. During the pseudo-bonus, for example, a high certainty number of games is given according to the winning combination.
- A case where a predetermined winning combination (for example, a so-called rare winning combination) is won by an internal lottery regardless of the gaming state.
・When the player wins the operation mode combination by internal lottery and the game is played in the second operation mode. For example, when the game section is the advantageous section and the third game state is the general game state, the high-precision number-of-games provision unit 1151 wins the second combination (for example, "1 piece combination") by the second operation mode. If you do, give a high certainty game number.

The period extension part 1152 is configured to be able to extend a special game period, which is a period during which a game can be played in a special game state (AT in this embodiment), according to at least a part of the given number of high-certainty games. .

In this embodiment, the period extension unit 1152 is configured to be able to extend the special game period according to the number of unplayed high-precision games among the given high-precision game numbers. Specifically, the period extension unit 1152 increases the special game period to be extended as the number of high-probability games increases.

A special game period extended when the number of high-probability games is larger than zero and smaller than a first threshold is defined as a first special game period, and a special game extended when the number of high-probability games is equal to or greater than the first threshold. Let the period be the second special game period. In this case, the period extension unit 1152 increases the special game period to be extended step by step so that the first special game period becomes shorter than the second special game period. For example, if the second threshold is a value smaller than the first threshold, the period extension unit 1152, if the number of high-probability games is greater than zero and less than the second threshold, RB the first special game period If the length of the equivalent (for example, 60) medals can be acquired, and the number of high-precision games is equal to or higher than the second threshold and is smaller than the first threshold, the first special game period is set to the equivalent of BB execution ( For example, 180) medals are set to a length that can be obtained. Also, for example, the period extension unit 1152 gives a number of parameters corresponding to the number of high-probability games, and determines the length of the second special game period according to the number of given parameters. The length of the second special game period is, for example, determined by calculation using the number of given parameters, or a lottery is conducted for the number of given parameters, and based on the results of the lottery It is determined.

For example, the period extension unit 1152 extends the special game period based on the end condition of the advantageous section and the current game information. Specific examples are shown below.
If the conditions for ending the advantageous interval include that the number of games that have elapsed since the advantageous interval was awarded reaches the first number of games played (for example, 1500 games), the period extension unit 1152 The special game period is extended when the second number of games from the number of games to the first number of games (that is, the number of remaining games until the end of the advantageous section) is equal to or less than a first predetermined value (for example, 300 games). do.
・If the conditions for ending the advantageous section include that the difference in the first payout of medals from the time the advantageous section was awarded to the present reaches the second payout difference (for example, 2400 medals), the period The extension part 1152 is configured such that the third payout difference number from the first payout difference number to the second payout difference number (that is, the remaining payout difference number until the end of the advantageous section) is a second predetermined value (for example, 900 coins). Extend the special game period in the following cases.

The measurement unit 116, for example, based on the game result determined by the game result determination unit 113, the number of games that have elapsed since the game interval was set to the advantageous interval (that is, the number of games completed in the advantageous interval), and To measure the payout difference number of medals after a game section is set as an advantageous section. Also, for example, the measurement unit 116 measures the time that has elapsed from a set starting point after all the reels 41, 42, and 43 have been rotating normally.

The setting value control unit 117 selects one setting value from among a plurality of setting values (six in this embodiment) that differ in the degree of advantage (for example, machine discount) to the game by the administrator operating the setting unit 45. set. The difference in the degree of advantage is realized, for example, by providing a difference in the probability of winning an internal lottery for a predetermined combination. In addition, the set value control unit 117 sets the rate of transition to the advantageous section, the degree of advantage related to ball output, such as AT lottery and AT additional lottery.

An example of how to set the setting value is shown below. This method is performed in the order of (1) to (7).
(1) Open the front door 20 .
(2) Turn off the main power of the slot machine 1; When the main power source of the slot machine 1 is turned off, all rotating reels 41, 42, and 43 are stopped, but winning determination is not performed by stopping the reels 41, 42, and 43.
(3) Insert a setting change key in a predetermined position of the setting section 45 to change the setting change mode from off to on.
(4) Turn on the main power of the slot machine 1;
(5) The current set value is displayed, for example, on the accumulated medal display section of the operation section 30 . By operating a predetermined button, the set value displayed on the reserved medal display portion is adjusted to a desired set value.
(6) Operate the start switch 33; By operating the start switch 33, the set value of the slot machine 1 is changed to the set value displayed on the stored medal display section.
(7) Change the setting change mode from ON to OFF and extract the setting change key.

The effect control unit 121 has a notification unit 1211, and determines the effect for each game based on the game state in which the internal lottery is performed and the result of the internal lottery. , and through the speaker 24, the determined effect is output.

The reporting unit 1211 reports information about the high-probability number of games (an example of the first reporting unit). For example, the information on the number of high-quality games includes the number of high-quality games that have not been consumed, the number of high-quality games that have been consumed, and the sum of the number of high-quality games that have been consumed and the number of high-quality games that have not been consumed, At least one of these information is notified. Notification of information on the special game period is performed using the liquid crystal display device 22, the illumination device 23, or the speaker 24, for example.

In addition, when the special game period is extended, the notification unit 1211 is configured to be able to notify the extension of the special game period using an icon representing the number of high-probability games (an example of the second notification unit). Notification of the extension of the special game period using the icon representing the number of high-probability games is performed using the liquid crystal display device 22, for example. As an example of an effect in which the extension of the special game period is announced, a plurality of medal-like icons are displayed, each icon is attached with a character representing the number of high-quality games played, and instead of the icon disappearing, There is an effect in which the number of extended games during the special game period is displayed.

Next, the extension processing of the special game period of the slot machine 1 will be described with reference to FIG. As an example, the processing described below is performed by the CPU executing a predetermined program.

As shown in FIG. 10, during AT, when the second number of games from the number of elapsed games to the first number of games (for example, 1500 games) is 300 games or less, or when an advantageous section is given When the third payout difference number from the first payout difference number of medals to the present until reaching the second payout difference number (for example, 2400 medals) becomes 900 or less (step S1), the period extension unit 1152 It is determined whether or not the number of unspent high-probability games is greater than or equal to the first threshold (step S2).

When it is determined that the number of unspent high-probability games is equal to or greater than the first threshold, the period extension unit 1152 extends the special game period by the second special game period, which has a larger extension amount than the first special game period. (Step S3), the special game period extension process ends.

When it is determined that the number of unspent high-probability games is smaller than the first threshold, the period extension unit 1152 extends the special game period by the first special game period, and the special game period extension process ends. . Specifically, the period extension unit 1152 determines whether or not the number of unspent high-probability games is greater than or equal to the second threshold and smaller than the first threshold (step S4). When it is determined that the number of unspent high-probability games is equal to or more than the second threshold and smaller than the first threshold, the period extension unit 1152 is equivalent to the BB implementation, that is, the number of balls obtained when the BB is implemented. The special game period is extended by the amount equivalent to (180) in the amount of balls that can be obtained (step S5). In addition, when it is determined that the number of unspent high-probability games is smaller than the second threshold, the period extension unit 1152 determines the amount equivalent to the RB implementation, that is, the number of payouts obtained when the RB is implemented (for example, 60 ), the special game period is extended (step S6).

The slot machine 1 can exhibit the following effects.

In the slot machine 1, a high-precision game number imparting unit 1151 configured to be capable of imparting a high-probability game number, which is the number of games that can be played in a high probability state, and at least part of the given high-probability game number and a period extension part 1152 configured to be able to extend a special game period, which is a period in which a game can be played in AT (an example of a special game state). With such a configuration, for example, it is possible to extend the special game period by using at least part of the number of highly-probable games accumulated by the player himself during the course of the game. As a result, it is possible to realize the slot machine 1 capable of providing new playability.

The slot machine 1 can arbitrarily employ one or more of the following configurations. In other words, any one or more of the following multiple configurations can be arbitrarily deleted when included in the above embodiment, and can be arbitrarily added when not included in the above embodiment. can. By adopting such a configuration, it is possible to realize the slot machine 1 that can more reliably prevent the player's desire to play from decreasing due to the end of the advantageous section.

A period extension part 1152 is configured to be able to extend the special game period according to the number of high-precision games that have not been played among the given high-precision game numbers. As a result, the unspent high-probability game number is also effectively used in the game. Therefore, it is difficult for the player to perceive that the number of high-probability games that have been accumulated in the course of the game so far but not consumed are wastefully accumulated. In addition, since the special game period is extended according to the unspent high-probability game number, the unspent high-probability game number is returned to the player as a ball. Therefore, the player can feel that the unspent high-probability game number is being used more effectively.

The period extension unit 1152 extends the special game period based on the end condition of the advantageous section and the current game information.

The conditions for ending the advantageous interval include that the number of games that have elapsed since the advantageous interval was granted reaches the first number of games, and the period extension unit 1152 reaches the first number of games from the number of elapsed games. The special game period is extended when the second number of games to be played is equal to or less than the first predetermined value. Thereby, when the number of remaining games that can be played in the advantageous section is limited to some extent, the special game period is extended according to the number of high-probability games. Since the high-probability number of games is effectively used as the end of the advantageous section approaches, it is possible to more reliably prevent the player's desire to play from declining due to the end of the advantageous section.

The condition for ending the advantageous interval includes that the first payout difference number of medals from the time when the advantageous interval is awarded to the present reaches the second payout difference number, and the period extension unit 1152 The special game period is extended when the third payout difference number from the number to the second payout difference number is equal to or less than a second predetermined value. As a result, the special game period is extended according to the number of high-probability games when the payout difference number of medals obtained in the advantageous section is limited to some extent. Since the high-probability number of games is effectively used as the end of the advantageous section approaches, it is possible to more reliably prevent the player's desire to play from declining due to the end of the advantageous section.

The period extension unit 1152 increases the extended special game period as the number of high-probability games increases. As a result, the higher the accumulated number of high-quality games, the more the number of high-quality games is returned to the player as a ball, so the player expects the extension of the special game period from the amount of the number of high-quality games. You can play while moving.

A special game period extended when the number of high-probability games is larger than zero and smaller than a first threshold is defined as a first special game period, and a special game extended when the number of high-probability games is equal to or greater than the first threshold. Assuming that the period is the second special game period, the period extension unit 1152 increases the extended special game period so that the first special game period is shorter than the second special game period. In this way, since the extension period of the special game period differs depending on the amount of high-precision games, in addition to advancing the game, the special game period is extended according to the amount of high-precision games. The fun of guessing how much it will be extended is added.

The period extension unit 1152 gives a number of parameters corresponding to the number of high-probability games, and determines the length of the second special game period according to the number of parameters. Since the length of the second special game period is determined through the number of parameters corresponding to the number of high-precision games, the length of the second special game period is uniquely determined by the number of high-precision games without passing through the parameters. It becomes difficult to know how long the second special game period will be, compared to when the second special game period is set. Therefore, when the special game corresponding to the second special game period is executed, the player can feel the fun of not knowing how long the special game will last. Therefore, the playability becomes richer in variety.

The high-precision game number provision unit 1151 is configured to be able to provide a high-precision game number not only when the game state is the normal game state, but also when the game state is AT. In this way, there are various opportunities for awarding a high-probability number of games, and the extension of the special game period can be expected accordingly.

A notification unit 1211 is provided for notifying information about the number of highly-probable games. As a result, the player can grasp the number of highly-probable games and play while expecting an extension of the special game period.

When the special game period is extended, a notification unit 1211 configured to notify the extension of the special game period using an icon representing the number of high-probability games is provided. By this notification content, the player can feel that the number of high-precision games accumulated in the past games is being used to extend the special game period.

The combination won by the internal lottery includes an operation mode combination in which the number of medals to be paid out changes based on the operation mode, and the operation mode includes a first operation mode and a second operation mode. The operation mode combination is configured such that the number of medals to be paid out according to the second operation mode is smaller than the number of medals to be paid out based on the first operation mode. The high-probability game number imparting unit 1151 imparts a high-probability state based on the game in the second operation mode when the operation mode combination is won. With such a configuration, when a player wins an operation mode combination, the player will play the game while being conscious of whether the game will end with a mere payout of medals, or whether a high probability state may be awarded. As a result, it is possible to realize the slot machine 1 capable of providing new playability.

The slot machine 1 can also be configured as follows.

The slot machine 1 is not limited to the above-described embodiment, and can employ any configuration including the high-precision number-of-games granting unit 1151 and the period extending unit 1152 . For example, the section control unit 114 and the notification unit 1211 can be omitted. Although the reporting unit 1211 serving as both the first reporting unit and the second reporting unit is provided in the above embodiment, the first reporting unit and the second reporting unit that are independent of each other may be provided. In the above-described embodiment, the wins to be won by internal lottery include the operation mode wins, but the wins to be won by internal lottery may not include the operation mode wins.

The period extension unit 1152 may be configured to be able to extend the special game period according to at least a part of the given high-certain game number. For example, the period extension unit 1152 may be configured to be able to extend the special game period according to a part or all of the undigested high-precision game number among the given high-precision game numbers, or may be configured to be able to extend the special game period. The special game period may be configured to be able to be extended according to part or all of the high-definite game number, or a special The game period may be configured to be extendable.

The period extension unit 1152 may be configured to extend the special game period based on other factors, not limited to the case based on the end condition of the advantageous section and the current game state.

In the first special game period, when the number of high-precision games is greater than zero and smaller than the second threshold, the length of medals corresponding to the execution of RB is set, and the number of high-precision games is the second threshold or more. and is smaller than the first threshold value, it is not limited to the case where the length is set so that the medals corresponding to the kind BB can be acquired. For example, the first special game period may be uniformly set to the same length without providing a threshold value, or a plurality of threshold values may be provided to set different lengths of 3 or more according to the number of high-probability games. may be set.

The slot machine 1 is not limited to the case of having the high-precision number-of-games provision unit 1151 and the period extension unit 1152, and can also be configured as shown in FIGS. 11 to 14. FIG. Each slot machine 1 of FIGS. 11 to 14 can also extend the special game period by using, for example, at least a part of the number of high-precision games accumulated by the player himself in the course of the game, and a new game can be played. can provide sexuality.

The slot machine 1 of FIG. 11 has an acquisition increasing section 1153 instead of the period extending section 1152 . Acquisition increasing unit 1153 is configured to be able to increase the number of medals that can be acquired during the special game period according to at least a part of the given number of high-precision games. The slot machine 1 of FIG. 12 includes a game medium conversion section 1154 instead of the period extension section 1152 . The game medium conversion unit 1154 is configured to be able to convert at least part of the given number of highly-probable games into medals obtainable during the special game period. The slot machine 1 of FIG. 13 has a period determination section 1155 instead of the period extension section 1152 . In the slot machine 1 of FIG. 13, the special game period includes a first period and a second period that starts after the first period ends. The period determination unit 1155 determines the length of the second period according to at least part of the given high-probability game number. The slot machine 1 of FIG. 14 includes a parameter determining section 1156 and a parameter converting section 1157 instead of the highly-probable number-of-games imparting section 1151 and the period extending section 1152 . The parameter determination unit 1156 determines a first parameter related to the special game state and a second parameter different from the first parameter and related to the expected degree of acquisition of game media (medals). Parameter conversion section 1157 is configured to be able to convert the second parameter into the first parameter. The first parameter corresponds to the length of the special game state, the number of wins in the special game state, and the like, and the second parameter corresponds to the length of the high probability state, the expectation of winning in the special game state, and the like. For example, when the second parameter is the length of the high-probability state, the parameter conversion unit 1157 is configured to convert the unused second parameter (that is, the number of unspent high-probability games) into the first parameter. ing.

The special game state is more advantageous for the player than the normal game state, and it is sufficient if the specification can extend the period in which the game can be played in the special game state. For example, the special game state is not limited to AT, and may be ART. A high probability state can also be included in the special game state. In this case, the high probability state transition lottery may be an example of the special game state lottery. An extended lottery in a high-probability state can also be included in the special game state lottery. Also, the special game state may be a set management type in which a predetermined number of games is set as one set, or may be a game number management type.

When the special game period is extended, the extended AT may be started continuously after the AT before the extension is finished, or after the AT before the extension is finished, the normal game state is temporarily entered. Afterwards, it may shift to AT again and the extended AT may be started.

When the advantageous section ends by satisfying the end condition, for example, the ending effect may be executed just before the end. During execution of the ending effect, the AT game period is not extended even if the extension condition is satisfied. Therefore, for example, when the ending effect is executed after reaching the 1450th game after moving to the advantageous section, the period extension unit 1152 can regard the first number of games to be 1450 games instead of 1500 games.

The end condition of the advantageous section includes, in addition to the case where the number of continuous games in the advantageous section reaches 1500 games or the number of payout differences reaches 2400, the period extension unit 1152 extends the special game period according to the number of high-certainty games. Granting (setting) an extension may be included. Triggered by the extension of the special game period according to the number of high-probability games, the section control unit 114 performs a reset process of temporarily ending the advantageous section and setting it to the advantageous section again. Even if this reset process is performed, it is preferable that the information that the extension of the special game period has been granted (set) is maintained. As a result, in the advantageous section after the reset process, a special game corresponding to the extension of the special game period provided (set) before the reset process is executed. For this reason, the constraint on the number of balls to be released due to the finite advantageous section (that is, the phenomenon in which the existence of the advantageous section does not make it possible to obtain a lot of balls) is alleviated.

In step S2 of FIG. 10, it is determined whether or not the unspent high-probability game number is equal to or greater than the first threshold value. It may be determined whether or not the number of high-probability games>zero.

The conditions for ending the advantageous interval (for example, “remaining number of Gs in advantageous interval” and “remaining difference number of sheets until the end of advantageous interval”) may be displayed on the liquid crystal display device 22 . Since the remainder of the playable period is displayed in the advantageous section, the player can be expected to extend the special game period.

The conditions for forcibly setting the advantageous interval to the normal interval by the interval control unit 114 are limited to the number of games completed in the advantageous interval reaching 1500 games and the number of medal payout differences in the advantageous interval reaching 2400. do not have. The advantageous section may be forcibly set to the normal section under conditions different from these conditions, or the condition for forcibly setting the advantageous section to the normal section may not be provided. For example, when the number of games played in the advantageous section reaches 1500 games, the advantageous section is forcibly set to the normal section. It may be configured so that it is not forcibly set in the section. Also, for example, except when the advantageous interval is forcibly set to the normal interval, once the game interval is set to the advantageous interval, a so-called bonus (for example, a kind of BB) is won once, or Alternatively, the advantageous section may not be set as the normal section until the pushing order of the pushing order that maximizes the payout of medals (for example, pushing order bell) is notified once.

When the setting value of the slot machine 1 is changed, the game section may be set to take over the state immediately before the setting value of the slot machine 1 is changed, or may be set to a preset initial state. (ie, initialized).

In the above-described embodiment, the instruction function is activated during the advantageous section, and the average ball output rate is obtained when the game is advanced so that the maximum number of payouts of small winning combinations is won, excluding the accessory and the accessory continuous actuating device. is more than 100%. For example, when the game section shifts to the advantageous section, the display unit may always display that the game is in the advantageous section.

In the above-described embodiment, when the game section shifts to the advantageous section, the section control section 114 is configured to display that the game section is the advantageous section via the display section provided in the operation section 30. However, it is not limited to this. For example, the liquid crystal display device 22 may be configured to serve also as a display section, or the display section may be omitted so as not to display that the game section is an advantageous section. After the advantageous section is displayed on the display section, the advantageous section may continue to be displayed until the advantageous section ends, or the advantageous section may not continue to be displayed.
