Description

  The present invention relates to a slot machine in which the winning probability of a special combination for shifting to a special game that is advantageous to a player changes (has a probability variation) according to the gaming state or the like.

  In a conventional slot machine, a three-game betting game (three medal insertions) and a two-game betting game (two medal insertions) are provided, and the normal gaming state is a three-betting game. A technique for making a two-bet game after the end of the game and increasing the winning probability of a big bonus in a two-bet game is higher than that in a three-bet game (see, for example, Patent Document 1).

  In addition, in a ball game machine, a technique (probability fluctuation) is known in which the jackpot winning probability is changed from a normal probability to a high probability. For example, as a jackpot, a normal jackpot and a probability variation jackpot are provided, and when the probability variation jackpot is reached, the jackpot probability is set high (for example, about 10 times) until the next jackpot after the jackpot game ends. .

  In the conventional ball game machine, when a normal jackpot is pulled, the game becomes a normal game after the end of the jackpot game, and when a probability variation jackpot is subtracted, the game becomes a probability variation game after the jackpot game ends. And if you pull the probability variation jackpot again during this probability variation game, the probability variation game will continue after the jackpot game ends, but when you usually pull the jackpot game, it will return to the normal game after the jackpot game ends. is there.

JP 2006-263029 A

  In the conventional ball game machine described above, when the probability variation jackpot is drawn is solely due to luck, it may be drawn just before the hall is closed. And even if you draw a probability variation jackpot just before the closing of the hall, after the jackpot game ends, the game ends (the game ends on that day with the end of the jackpot game), and you will benefit from the probability variation game after the jackpot game There was a problem that could not.

In addition, there are halls that provide a service that gives a certain profit to the player who has won the probability variation jackpot just before closing the store, but when the store closes, no matter what gaming state the store is closed Is generally terminated.
For this reason, when viewed from the player's side, there are few merits to be close to closing the store and to draw a probability variation jackpot, so there are many players who end the game with a margin for the closing time.
Therefore, in the hall, there has been a problem that the operation rate when the store is closed is greatly reduced.

Even if the same probability variation as that of the ball game machine is applied to the slot machine using the technique described in the cited document 1, it is considered that the same problem as that of the ball game machine occurs.
Therefore, the problem to be solved by the present invention is to reduce the above-mentioned problem of availability by using a portion unique to a slot machine that is not in a ball game machine when executing a probability variation game in a slot machine. is there.

The present invention solves the above-described problems by the following means. An embodiment corresponding to parentheses is shown.
According to the first aspect of the present invention, a lottery drawing means (61) for drawing a combination with a winning probability of a combination corresponding to the number of inserted game media (medals), and a special combination (1BBA, 1BBB, RB) ), And when the combination of symbols corresponding to the special role is stopped on the active line, a special game that is controlled to execute a special game (1BBA game, 1BBB game, RB game) that is advantageous to the player Control means (68), and has at least three game media as M1 (1), M2 (2), and M3 (3) as the number of game media that can be inserted into the slot machine. , Having at least two types of special roles B1 (1BBA) and special role B2 (1BBB), and having a normal probability game and a high probability game (X and Y) as the gaming state, In the normal probability game In the high-probability game, a lottery of the roles including the special role B1 and the special role B2 is performed, and the winning probability of at least one of the special roles is determined in the high probability game. Set higher than the winning probability of the special role in the normal probability game. In the normal probability game, the game can be played with the number of inserted game media M3, and the game can be played with the number of game media inserted M1 or M2. In the high-probability game, the player can select and play any one of the game media input numbers M1 or M2, and the game media input number M3 allows a game to be played. Set so that it cannot be done.

  And, with the setting value that determines the payout rate of the slot machine being constant, the symbol combination corresponding to the winning combination by the winning lottery means in the game is always stopped at the active line and acquired by the symbol combination When the game for which the maximum number of possible game media is to be acquired is a virtual game, the expected value of the number of payouts with respect to the number of game media input when the virtual game is played N1 times with the number of game media input M1 Is set to E1, and the play rate when the virtual game is played N1 times with the number M2 of game media inserted is set to E2 (E2 <E1). The payout rate when the virtual game is played N2 (N2> N1) times with the input number M1 is set to E3, and when the virtual game is played N2 times with the input number M2 of game media Rate is E4 (E4> E3) Characterized in that it is set.

  According to a second aspect of the present invention, in the slot machine according to the first aspect, the winning probability of the special role B1 is set to P1 in the normal probability game, and P1 ′ (P1 ′> P1) in the high probability game. In the high-probability game, the winning probability P1 ′ of the special role B1 is set higher than the winning probability P2 ′ of the special role B2, and the combination of symbols corresponding to the special role B1 is an effective line. When the special game is executed after being stopped, the game after the end of the special game is set to the high-probability game, and the combination of symbols corresponding to the special role B2 is stopped on the active line. Is executed, the game after the end of the special game is set as the normal probability game.

  The invention of claim 3 is the slot machine according to claim 1 or 2, further comprising a bet switch (40) operated by a player when a game medium electrically stored in the slot machine is inserted. The bet switch includes a maximum bet switch (40b) for inserting the maximum number of game media that can be input in the game, and a 1 bet switch (40a) for inputting the minimum number of game media, In the normal probability game, when the maximum bet switch is operated, the number of inserted M3 is controlled on condition that the number of game media are electrically stored, and the 1-bet switch Is operated once, on the condition that the number of game media is electrically stored, the insertion number M1 (M1 <M3) is to be inserted. In addition, when the 1-bet switch is operated a plurality of times, the maximum number of insertions M3 is controlled to be inserted. In the high probability game, when the maximum bet switch is operated, the number of On the condition that the game medium is electrically stored, control is performed so that the larger one of the inserted numbers M1 or M2 is inserted, and when the 1-bet switch is operated, the number of operations Regardless of whether or not the number of game media is electrically stored, control is performed so that the smaller one of the number M1 or M2 is inserted.

  A fourth aspect of the present invention is the slot machine according to any one of the first to third aspects, further comprising a start switch (41) operated by a player when starting the rotation of the reel. The timer (64a) for measuring the time from when the start switch is operated until the start switch is operated in the next game is determined, and it is determined that the measurement result by the timer has not passed the predetermined time. When there is a weight means for controlling the reel to start rotating after the predetermined time has elapsed, the weight means sets the predetermined time to T1 in the normal probability game, and in the high probability game The predetermined time is set to T2 (T2 <T1).

  According to a fifth aspect of the present invention, in the slot machine according to any one of the first to fourth aspects of the present invention, the combination lottery means includes both a small combination and a replay in both the normal probability game and the high probability game. The replay winning probability is set higher in the high probability game than in the normal probability game, and the winning probability of the small role is higher than that in the normal probability game and the high probability game. The number of game media payout when the combination of symbols corresponding to the small role is stopped on the active line is set to be different between the normal probability game and the high probability game. The high probability game is characterized in that a payout rate is set to be lower than 1 and higher than the payout rate of the normal probability game.

(Function)
In the present invention, the normal probability game is set so that a game can be performed with the number of inserted game media M3 and a game cannot be performed with the number of game media inserted M1 or M2. On the other hand, in the high probability game, the player can select any one of the number of inserted game media M1 or M2 and play the game, and the game cannot be played with the game media input number M3. Is set to

In the high probability game, the payout rate when the virtual game is played N1 times with the number M1 of game media inserted is E1, and the playout rate when the virtual game is played N1 times with the number M2 of game media inserted Is set to E2 (E2 <E1).
On the other hand, when the virtual game is played N2 (N2> N1) with the number of inserted game media M1, the payout rate when the virtual game is played N2 times with the number of inserted game media M2 is E4 (E4> E3) is set.

  According to the present invention, if a high probability game is played with the number M1 of game media inserted, it is advantageous for a small number of games, and if a high probability game is performed for a number M2 of game media inserted, it is advantageous for a large number of games. For this reason, the player can arbitrarily select a player who is more advantageous according to the number of remaining games (game time) until the game is finished. Therefore, the gaming state can be selected according to the number of inserted medals according to the convenience of the player.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing an outline of control of the slot machine 10 in the present embodiment. The slot machine 10 includes a game (main) control means 50 and an effect (sub) control means 70.

  The game control means 50 controls the progress of games such as winning lottery, reel 31 drive control, and payout at the time of winning, and is provided on a main control board (not shown). A CPU for performing a game, a ROM for storing a program necessary for the progress of the game, a RAM for temporarily storing data taken in when the CPU performs various controls, and the like.

  The effect control means 70 controls the output of game information and game information during the game and in the game standby. The effect control means 70 is provided on a sub-control board (not shown), and a CPU that performs calculations, a ROM that stores data for effects (such as effect patterns), and a CPU perform various effects. A RAM or the like for temporarily storing data taken in when outputting is provided.

  The sub control board is a control board belonging to a lower level of the main control board. The game control means 50 and the effect control means 70 are electrically connected, and are configured so that signals and information (commands) are transmitted from the game control means 50 to the effect control means 70 in one direction. .

As shown in FIG. 1, on the input side (left side in FIG. 1) of the game control means 50, a bet switch 40, a start switch 41, a (left, middle, right) stop switch 42, and a setting change switch 44 are electrically connected. Connected.
The bet switch 40 is a switch operated when the player inserts a stored medal for the game. In the present embodiment, the maximum number of medals inserted in one game is set to three, and there are two one-bet switches 40a and a maximum bet switch (maximum three) switch 40b.
Then, the player inserts the number of medals that can be inserted in one game (one type or any one of a plurality of types) according to the gaming state described later, and plays the game. The relationship between the game state and the number of medals that can be inserted will be described later.

  The medal insertion slot 43 is a part where the player inserts an actual medal. Inserting a medal from the medal insertion slot 43 plays the same role as operating the bet switch 40.

Furthermore, the start switch 41 is a switch operated by the player when starting the reels 31 (all of left, middle, and right).
Furthermore, three (left, middle, right) stop switches 42 are provided corresponding to the three (left, middle, right) reels 31, and the player operates to stop the corresponding reels 31. Switch.

  Further, the setting change switch 44 is operated when changing / setting the setting value of the slot machine 10. The setting value has six stages from setting 1 to setting 6, and is set such that the higher the setting value, the more advantageous to the player (the higher the probability of winning the special role). The setting change switch 44 is not operated by the player, but is operated at the store (hall) side of the slot machine 10 and is disposed inside the slot machine 10 so that it cannot be operated by the player. ing.

Further, a high probability release switch 44 a and an RT release switch 44 b are provided along with the setting change switch 44.
When the setting change is made, the high probability release switch 44a is used to release the gaming state after the setting change when the slot machine 10 is turned off and the high probability game is in progress (details will be described later). Similar to the setting change switch 44, this switch is operated by an operator at the installation store (hall) side that determines the set value.

In addition, the RT release switch 44b releases the gaming state after the setting change when the setting change is made and the RT game is in progress (details will be described later) when the power of the slot machine 10 is turned off (details will be described later). As with the setting change switch 44, it is operated by an operator on the installation store (hall) side that determines the set value.
When the setting is changed, it is automatically set to a normal probability game when the game state before the setting change is a high probability game, or set to a non-RT game when the game is an RT game. Is possible. Furthermore, at the time of setting change, in addition to the case where both game states are set as described above, only one of the game states can be set as described above.

Three motors 32 are electrically connected to the output side (right side in FIG. 1) of the game control means 50.
The motor 32 is for rotating the reels 31, is connected to the center of rotation of each reel 31, and is controlled by a reel control means 64 described later. Here, the reel 31 includes a left reel 31, a middle reel 31, and a right reel 31, and a stop switch 42 that is operated when the left reel 31 is stopped is the left stop switch 42, and when the middle reel 31 is stopped. The stop switch 42 to be operated is the middle stop switch 42, and the stop switch 42 to be operated when stopping the right reel 31 is the right stop switch 42.

  The reel 31 is ring-shaped, and a reel tape on which a plurality of types of symbols (designs constituting a combination of symbols corresponding to the combination) is attached is attached to the outer peripheral surface thereof. FIG. 2 is a diagram showing a symbol arrangement of the reels 31 in the present embodiment. In FIG. 2, symbol numbers are also shown. As shown in FIG. 2, in this embodiment, 21 symbols are arranged at equal intervals for each reel 31.

  FIG. 3 is a view showing the positional relationship between each reel 31 and a display window (transparent window) 11 provided in the front mask portion (front door, not shown) of the slot machine 10. In this embodiment, three reels 31 (left reel 31, middle reel 31, and right reel 31) are provided in parallel in the horizontal direction in this embodiment. Further, each reel 31 is arranged so that three symbols that are continuous in the vertical direction can be seen from the display window 11. Therefore, the display windows 11 of the slot machine 10 are arranged so that a total of 3 × 3 = 9 symbols can be seen.

  In this specification, in FIG. 3, the position where the “RP” symbol of the left reel 31 is stopped is “upper”, and the position where the “red 7” symbol of the left reel 31 is stopped is “middle”. The position where the symbol “BAR” of the left reel 31 is stopped is referred to as “lower stage”.

Further, as shown in FIG. 3, symbol combination lines L <b> 1 to L <b> 5 are provided in a portion including the display window 11 of the slot machine 10.
Here, the “symbol combination line” is a line of symbols when the reel 31 is stopped, and is a line that forms a combination of symbols. In the present embodiment, a total of five symbol combination lines L1 to L3 in the middle, upper, and lower stages in the horizontal direction, and two symbol combination lines L4 and L5 in the diagonally right-down direction and diagonally right-up direction. Has a symbol combination line.

In addition, the symbol combination line has an effective line and an invalid line.
Here, the “effective line” is a line for winning a winning combination when a combination of symbols corresponding to any of the winning combinations is stopped on that line.
On the other hand, an “invalid line” is a line that is not set as an effective line among symbol combination lines, and even if a combination of symbols corresponding to any combination stops on that line, This is a line that does not give profits (medal payout etc.). In other words, the invalid line is a line that is not a target of combination of symbols in the first place.

  The effective line and the invalid line are set according to the number of inserted medals, the game state, and the like. In the present embodiment, as described above, the game is performed with one to three according to the game state. Is set to In the present embodiment, all five symbol combination lines L1 to L5 are effective lines regardless of the number of medals inserted. Therefore, in this embodiment, the invalid line is set so as not to exist.

However, the present invention is not limited to this, and only a part of the five symbol combination lines L1 to L5 may be set as valid lines (the rest are invalid lines) in accordance with the number of inserted medals and the gaming state.
In addition, the effective line is not limited to the linear shape shown in FIG. 3, but various types such as V type (upper stage-lower stage-upper stage), inverted V type (lower stage-upper stage-lower stage), and L type (upper stage-lower stage-lower stage) The aspect of this is mentioned.

Further, in FIG. 1, production output devices such as the lamp 21, the speaker 22, and the image display device 23 are electrically connected to the output side of the production control means 70.
The lamps 21 are effects lamps for the slot machine 10 and are turned on in a predetermined pattern when predetermined conditions are satisfied. The lamp 21 is arranged on the inner peripheral side of each reel 31 and a back lamp (not shown) for illuminating from behind the symbols displayed on the reels 31 (three symbols that are continuously visible from the display window 11). ), And an upper lamp and a side lamp (not shown) which are arranged on the front surface of the housing of the slot machine 10 and blink when a winning combination is made.

The speaker 22 outputs a predetermined sound when a predetermined condition is satisfied in order to perform various effects during the game.
Furthermore, the image display device 23 includes a liquid crystal display, a dot display, and the like, and displays various effect images and the like during the game.

FIG. 4 is a diagram showing combinations of combinations of types (combinations drawn by the combination lottery means 61 described later), the number of payouts, and the like in the present embodiment. As shown in FIG. 4, as the combination, a special combination, a small combination, a replay, and a game state transition combination are provided.
A combination of symbols corresponding to each combination and the number of payouts at the time of winning are determined. As a result, when all the reels 31 are stopped, when the combination of symbols corresponding to any of the combinations stops on the active line and the winning combination of the combination is won, the number of medals corresponding to the combination is paid out (however, Excluding special roles and replays).

  In the role, first, the special role is a role that shifts from a normal game to a special game (a game that has a higher game play rate than a normal game and is advantageous to the player). In the present embodiment, 1BB (first type big bonus) and RB (regular bonus) are provided as special combinations. When 1BB wins, no medal is paid out in the game, but the next game shifts to 1BB game which is one of the special games. Similarly, when the RB wins, there is no payout of medals in the game, but the next game shifts to the RB game which is another one of the special games.

Furthermore, as shown in FIG. 4, 1BB is provided with two types, 1BBA and 1BBB. These are all set so that the combination of symbols is different, and each is a combination that is drawn independently. When 1BBA wins, it shifts to 1BBA game which is one of 1BB games, and when 1BBB wins, it shifts to 1BBB game which is another one of 1BB games.
Also, there is only one type of RB in the present embodiment.
Furthermore, 1BBA is 1BB (probability variation BB) that can be shifted to a high probability game (probability variation game) after the end of 1BBA game.
On the other hand, 1BBB is 1BB (normal BB) that can be shifted to a normal probability game (non-high probability game) after the end of the 1BBB game.

  Other special roles include 2BB (second-type big bonus, also referred to as MB (middle bonus)) and SB (single bonus), which are not provided in this embodiment.

The small role is a role in which a predetermined number of medals are paid out. In this embodiment, the small role includes 1 to 3 and a combination of different symbols is set for each small role. ing. Note that “any” in the small part 1 means that any symbol may be used.
In addition, the replay is a re-playing role that enables the re-playing while maintaining the number of medals inserted in the game.
In addition, as shown in FIG. 4, the small number 1, the small number 2, and the small number 3 have different payout numbers at the time of winning for each gaming state (normal probability game, high probability game X, and high probability game Y). Is set to

In each of the above-mentioned combinations, if the combination of symbols corresponding to the combination does not stop on the active line in the game selected for the combination, a combination that is carried over after the next game and a combination that is not carried over are determined. .
Special roles (1BB and RB) are mentioned as the carry-over. When the special combination is won, in the game until the combination of symbols corresponding to the special combination stops on the active line when the reel 31 is stopped, the special combination is controlled to be carried over from the next game onward.

  In this way, the winning of the special role is carried over, while the small role and replay which are roles other than the special role are not carried over. When a role other than the special role is won in the lottery of the role, the winning role is valid only in the game, and the winning is not carried over after the next game. In other words, in the game where these winning combinations are won, the reel 31 is controlled to stop so that the combination of symbols corresponding to the winning combination can be stopped (winning) on the active line. Regardless, at the end of the game, the right to the winning role will cease.

  At the start of the game, the player operates the bet switch 40 (40a or 40b) to insert a previously stored medal, or inserts a predetermined number of medals from the medal insertion slot 43 and operates the start switch 41. (ON). When the start switch 41 is operated, a signal generated at that time is input to the game control means 50. When the game control means 50 (specifically, the reel control means 64 described later) receives this signal, it controls to drive all the motors 32 and rotate all the reels 31. As the reel 31 is rotated by the motor 32 in this way, the symbols on the reel 31 are moved and displayed in the vertical direction in the display window 11 at a predetermined speed.

  Then, the player presses the stop switch 42 to stop the rotation of the reel 31 corresponding to the stop switch 42 (for example, the left reel 31 corresponding to the left stop switch 42). When the stop switch 42 is operated, a signal generated at that time is input to the game control means 50. When the game control means 50 (specifically, the reel control means 64 described later) receives this signal, the game control means 50 controls the drive of the motor 32 corresponding to the stop switch 42 and controls the stop of the reel 31 related to the motor 32. I do. When all of the reels 31 are stopped, when a combination of symbols corresponding to any of the combinations stops on the active line (when the winning combination of the combination is awarded), a medal corresponding to the winning combination is paid out. Done.

  As shown in FIG. 1, the game control means 50 includes the following set value changing means 60 and the like. The following means in the present embodiment are examples, and the game control means 50 is not limited to the means shown in the present embodiment.

The setting value changing means 60 is for changing / determining a setting value that determines the payout rate of the slot machine 10. In particular, in the present embodiment, six stages from setting 1 to setting 6 are provided as setting values, and the higher the setting value, the higher the payout rate (the higher the probability of winning the special role). Yes.
The set value changing means 60 is provided with a set value storage means 60a (memory such as RAM) for storing the set values, and stores the determined set values in the set value storage means 60a.
The set value stored in the set value storage means 60a is transmitted to the effect control means 70, and the set value is also set on the effect control means 70 side.

Further, when the slot machine 10 is turned off during the high probability game and started in the setting change mode, the high probability game can be turned off. When the high probability release switch 44a is turned on during the setting change mode, the high probability game up to that point is set to the normal probability game at the next power-on.
Similarly, the RT game can be turned off during the setting change mode. When the RT release switch 44b is turned on during the setting change mode, the previous RT game is set to a non-RT game when the next power is turned on.

The game state control means 69, which will be described later, includes a high probability flag 69a for determining whether or not the game is in a high probability game, and RT for determining whether or not the game is in an RT game. A flag 69b is provided.
During the high probability game, the high probability flag 69a is turned on. However, when the high probability release switch 44a is turned on during the setting change mode, the signal is transmitted to the game state control means 69, and the high probability flag 69a is turned on. The probability flag 69a is turned off from on.

  Similarly, during the RT game, the RT flag 69b is turned on. However, when the RT release switch 44b is turned on during the setting change mode, the signal is transmitted to the gaming state control means 69 and the RT flag 69a. Is turned off from on.

  The role lottery means 61 performs lottery for a role (the special role, the small role, and the replay described above). The role lottery means 61 is based on, for example, a random number generation means (hardware random number, etc.) for a role lottery, a random number extraction means for extracting a random number generated by the random number generation means, and a random value extracted by the random number extraction means. And determining means for determining the presence / absence of a winning combination and the winning combination.

  The random number generation means generates random numbers in a predetermined area (for example, 0 to 65535 in decimal notation). The random number is, for example, a random number for which the counter that performs 1 count at 200 n (nano) sec continues to count as a cycle in the range of 0 to 65535, and continues to count the random number while the slot machine 10 is powered on. .

  The random number extraction means extracts the random number generated by the random number generation means at a predetermined time, in the present embodiment, when the start switch 41 is operated (turned on) by the player. The determination unit determines the combination corresponding to the region to which the random number value belongs by comparing the random number value extracted by the random number extraction unit with a combination lottery table 62 described later. For example, if the extracted random value belongs to the 1BBA winning area, it is determined to be 1BBA winning, and if it belongs to the non-winning area, it is determined not to win.

  The combination lottery table 62 defines the types of combinations to be selected and the winning probability of each combination. The role lottery table 62 is provided for each gaming state. Each combination lottery table 62 has a predetermined range of lottery areas. The lottery area is divided into a winning area and a non-winning area for each combination, and the winning combination has a predetermined winning probability. It is set to a predetermined ratio so that

FIG. 5 is a diagram for explaining the types of gaming states of the present embodiment.
First, the “game state” of the present embodiment includes a normal game and a special game. In the present embodiment, “special game” includes 1BBA game, 1BBB game, and RB game. The “normal game” refers to a game other than a special game, and includes a normal probability game and a high probability game.

Furthermore, the high probability game includes a high probability game X and a high probability game Y.
Furthermore, in this embodiment, the normal probability game is always a non-RT game, but the high probability game is an RT game from the first game to the 50th game, and is a non-RT game after the 51st game.
Here, “RT (Replay Time) game” means a gaming state in which the winning probability of replay is different from that of non-RT gaming in a broad sense, and a gaming state in which the winning probability of replay is higher than that of a non-RT game in a narrow sense. And RT game of this embodiment is the latter.

  In an RT game with a high replay winning probability, the player frequently wins / wins a replay, increasing the chance of proceeding to the next game without inserting a game medium. Also, if the winning probability of replay is high, the payout rate (ratio of medal insertion number and medal payout number) approaches “1”, so the player does not reduce the medal possession number during RT game. The game can be continued.

Furthermore, all the normal games have a non-internal medium game and an internal medium game.
Here, the “non-internal game” means a game that has not been won for a special role (a game in which the special role has not been carried over).
In addition, the “internal game” means that a special combination is won in the game or a game before the game, but the combination of symbols corresponding to the selected special combination is not stopped on the active line (the prize has been won). No) refers to a game (a game in which the winning of special role is carried over).

FIG. 6 is a diagram showing the base game lottery tables 62 </ b> A to 62 </ b> C of the base lottery table 62.
In FIG. 6, a combination lottery table 62A is a combination lottery table 62 used in a normal probability game (non-RT game).
In the part lottery table 62A, special winnings (1BBA, 1BBB, and RB), small part 1, small part 2, small part 3, and replay are selected separately, and small part 1 and small part 3 are overlapped. It has been. In FIG. 6, “+” means overlapping (simultaneous) winning in the game of a plurality of roles. Therefore, in FIG. 6, “small combination 1 + small combination 3” means overlapping winning combination of small combination 1 and small combination 3.

Furthermore, FIG. 7 is a diagram showing the winning probability of the special role in FIG. As shown in FIG. 7, the winning probability of the special role is determined for each set value, and is set so as to increase as the set value increases (however, the adjacent set value is set to the same value). In some cases).
Note that in the role lottery tables 62A to 62C, the internal lottery game lottery table 62 is different from the non-internal middle game role lottery table 62 only in that special roles are not lottery. In other words, once a special role is won in a non-internal game, it becomes an internal game and the special role will not be drawn until the special role is won (However, as will be described later, The winning of special role will be maintained until winning.)

  Further, in FIG. 6, a role lottery table 62B is a role lottery table 62 used in the high probability game X, and a role lottery table 62C is a role lottery table 62 used in the high probability game Y. Similar to the lottery table 62A, a non-internal medium game and an internal medium game are provided.

Furthermore, the high probability game is a game in which the winning probability of at least one special role is set higher than the winning probability of the special role in the normal probability game (see FIG. 7). How much is set depends on the specification of the payout rate, but for example, it is set in a range of 3 to 10 times.
Particularly in the present embodiment, in the high probability game X (role lottery table 62B), the winning probability of 1BBA is set high, and in the high probability game Y (role lottery table 62C), the winning probability of 1BBB is set high. Yes.

Since the winning probability of the special role is determined for each set value as shown in FIG. 7, the winning probability of any one special role in the normal probability game and the winning probability of the special role in the high probability game Are compared with each other, the winning probability of at least one special role is set higher than the winning probability of the special role in the normal probability game on condition that the same set value is used.
Therefore, although this is not the case in this embodiment, for example, the winning probability of any one special role at the normal probability game setting value 6 is the winning probability of the special role at the high probability game setting value 1. It may be higher than the probability.

Further, in the present embodiment, when a game is played with two inserted medals, the game becomes a high probability game X, and when a game is played with one inserted medal, the game becomes a high probability game Y.
Therefore, the player can set the high probability game X or the high probability game Y for each game according to the number of inserted medals for each game.

In addition, both the high probability game X and the high probability game Y are RT games from the first game to the 50th game, and non-RT games after the 51st game.
For this reason, for example, in the role lottery table 62B (high probability game X), the winning probability of replays from the 1st to 50th games is 1/5 (less than 1 / 7.3 which is the winning probability of replaying normal probability games) High) is set, and after the 51st game, it is set to the same value as the winning probability (1 / 7.3) of the replay of the normal probability game.

Similarly, in the winning lottery table 62C (high probability game Y), the winning probability of replays from the 1st to 50th games is 1 / 1.5 (from 1 / 7.3, which is the winning probability of replaying normal probability games). Is set to the same value as the winning probability (1 / 7.3) of the replay of the normal probability game.
In particular, in this embodiment, the winning probability of the RT game replay in the high probability game Y is set higher than the winning probability of the RT game replay in the high probability game X.

Further, FIG. 8 is a diagram showing a part lottery table 62D for special games (1BBA game, 1BBB game, and RB game) in the part lottery table 62.
In the combination lottery table 62D, only the small combination 1, the small combination 2, and the small combination 3 (single winning) are drawn, and the winning probability of the small combination 3 is set high. That is, in the special game, almost every game, a game state in which the small role 3 is elected alone.

  Note that the general combination lottery table 62 is normally provided for each number of medals that can be inserted, but in this embodiment, the number of medals inserted is determined to be only three in the normal probability game and the special game. In a high-probability game, when a game is played with two medal insertions, the game becomes a high-probability game X, and when a game is played with one medal-insertion, the game becomes a high-probability game Y. Therefore, the winning probability of the winning combination is not set to be different depending on the number of inserted medals in one winning lottery table 62.

Returning to FIG.
The winning flag control means 63 controls the on / off of the winning flag 63a corresponding to each winning, based on the winning lottery result by the winning lottery means 61. In the present embodiment, 1BBA, 1BBB, RB, small combination 1, small combination 2, small combination 3, and replay winning flags 63a are provided so as to correspond to the winning combination. When winning in the lottery of the combination by the combination lottery means 61, the winning flag 63a of the corresponding combination is turned on (the winning flag 63a is set). For example, when the replay is won, the winning flag 63a related to the replay is turned on, and the winning flags 63a of other combinations remain off.

In addition, as described above, since the winning of the small role and the replay are not carried over, even if these roles are won in the game and the winning flag 63a of these roles is turned on, the winning is made at the end of the game. The flag 63a is turned off.
On the other hand, since the winning of the special role is carried over, when the special role is won in the game and the winning flag 63a related to the selected special role is turned on, the ON state is kept until the special role is won. It is maintained and turned off when the special role wins.

  For example, when 1BBA is won in the game, the 1BBA winning flag 63a is turned on, and when 1BBA is not won in the game, the winning flag 63a related to 1BBA is kept on. Then, in the next game (internal game), when the small combination 2 is won, the winning flag 63a of the small combination 2 is turned on in addition to the winning flag 63a related to 1BBA which is already on. When 1BBA is not won at the end of the game, the winning flag 63a for the 1BBA is kept on and the winning flag 63a for the small combination 2 is turned off.

  In addition, when the winning combination of the small roles 1 and 3 is won in the game, both winning flags 63a of the small roles 1 and 3 are turned on, and both winning flags 63a are turned off at the end of the game. .

  When the reel control means 64 receives a rotation start command for the reel 31, especially in this embodiment, when the start switch 41 is operated (when a signal indicating that the start switch 41 is operated) is received ( The three reels 31 are controlled to start rotating.

Further, in this embodiment, one game time is set from when the start switch 41 is operated in the previous game to when the start switch 41 is operated in the game, and control is performed so that this one game time is measured. Therefore, the reel control means 64 includes a timer 64a for measuring the one game time.
Then, when it is determined that the measurement result by the timer 64a has not reached the predetermined time, the reel 31 is controlled to start rotating after reaching the predetermined time (weight means).

  Even when the predetermined time has not elapsed from the time when the start switch 41 is operated in the previous game to the time when the start switch 41 is operated in the previous game, when the start switch 41 is operated, as described above, The lottery will be held. Although the lottery is performed, the reel 31 does not start rotating during the weighting.

Furthermore, in the present embodiment, the predetermined time (wait time) is set to be different depending on the gaming state.
During the normal probability game and the special game, the predetermined time is set to “4.1 seconds”. In the high-probability game X, the predetermined time is set to “3.5 seconds”. Furthermore, in the high probability game Y, the predetermined time is set to “1.7 seconds”. That is, the high probability game is set to have a shorter wait time than the normal probability game, and the high probability game Y is set to have a shorter wait time than the high probability game X.
Therefore, in the high probability game, the game can be digested (progressed) at a higher speed than in the normal probability game (one game time can be shortened), and in the high probability game Y, the game is faster than the high probability game X. The game can be digested.

  Further, the reel control means 64 refers to the ON / OFF of the winning flag 63a in the game after the winning lottery is performed by the winning lottery means 61, and the stop position determination table corresponding to ON / OFF of the winning flag 63a. 65, and when the stop switch 42 is operated, the stop position of the reel 31 corresponding to the stop switch 42 is determined based on the timing when the stop switch 42 is operated, and the motor 32 is turned on. Drive control is performed to stop the reel 31 at the determined position.

  For example, in a game in which at least one winning flag 63a is on, the reel control means 64 has a symbol corresponding to the winning combination (the combination for which the winning flag 63a is on) within the range of stop control of the reel 31. The reel 31 is controlled so that the combination can be stopped on the effective line, and the reel 31 is controlled so that the combination of symbols corresponding to a combination other than the winning combination (the combination in which the winning flag 63a is off) is not stopped on the effective line. Stop control.

  Here, “within the range of stop control of the reel 31” means within the range of the maximum rotation amount (maximum number of moving symbols) of the reel 31 from the moment when the stop switch 42 is operated until the reel 31 actually stops. This means that in this embodiment, the number of moving symbols from the symbol at the moment when the stop switch 42 is operated is within 4 symbols (within 5 symbols including the symbol at the moment when the stop switch 42 is operated), in other words, the stop switch The time from the moment when 42 is operated until the reel 31 stops is set within 190 ms.

  Thus, when any of the symbols within the range of the stop control of the reel 31 counted from the symbol at the moment when the operation of the stop switch 42 is detected is a symbol to be stopped on the effective line, the stop switch 42 is operated. When that happens, the symbol is controlled to stop at the active line.

  That is, if the reel 31 is stopped immediately at the moment when the stop switch 42 is operated at the time of winning the winning combination, the reel 31 stopping control is performed when the reel 31 stops when the symbol related to the winning winning combination does not stop on the effective line. By controlling the rotational movement of the reel 31 within the range, the symbol related to the winning combination is controlled so as to be stopped on the effective line as much as possible.

  Conversely, if the reel 31 is stopped immediately at the moment when the stop switch 42 is operated, if the symbol combination corresponding to the winning combination is stopped on the effective line, the reel 31 is stopped when the reel 31 is stopped. By controlling the rotational movement of the reel 31 within the range of 31 stop control, the combination of symbols corresponding to the winning combination is controlled so as not to stop on the effective line.

  Further, the reel control means 64 controls the combination of symbols corresponding to any one combination to be stopped on the effective line in a game in which a plurality of winning flags 63a are on, and the symbols corresponding to the plurality of combinations are controlled. The reels 31 are controlled to stop so that the combination does not stop at the effective line at the same time.

  The stop position determination table 65 is provided for each of the ON / OFF states of the winning flag 63a, and determines the stop position of the reel 31 with respect to the position of the reel 31 at the moment when the stop switch 42 is operated. It is. Specifically, in each stop position determination table 65, for example, the stop switch 42 is operated at the moment when the 0th symbol (“bell” in the case of the left reel 31) passes the upper stage (middle stage or lower stage is acceptable). The stop position is determined such that the number of symbols is controlled to move and the number of symbols is stopped in the upper stage.

The stop position determination table 65 includes the following tables.
The 1BBA table is used when the 1BBA (only) winning flag 63a is on (when 1BBA is won in a non-internal game or when a role is not won in an internal game of 1BBA), and the reel 31 is stopped. Within the scope of control, when the combination of symbols corresponding to 1BBA is stopped on the effective line and the combination of symbols corresponding to 1BBA cannot be stopped on the effective line, the combination of symbols corresponding to any combination The stop position of the reel 31 is determined so as not to stop at the effective line.

  The 1BBB table and the RB table are the same as the 1BBA table. That is, the 1BBB table and the RB table correspond to those obtained by replacing “1BBA” with “1BBB” and “RB” in the 1BBA table, respectively.

  The small combination 1 table is used when the winning flag 63a of the small combination 1 (only) is on, and stops the combination of symbols corresponding to the small combination 1 on the effective line within the range of stop control of the reel 31. In addition, when the symbol combination corresponding to the small combination 1 cannot be stopped on the effective line, the stop position of the reel 31 is determined so that the symbol combination corresponding to any combination is not stopped on the effective line. Is.

  The small role 2 table, the small role 3 table, and the replay table are the same as the small role 1 table. That is, in the small role 2 table, the small role 3 table, and the replay table, in the small role 1 table, “small role 1” is read as “small role 2”, “small role 3”, and “replay”, respectively. It corresponds to a thing.

  In addition, the winning combination table for the small role 1 and the small role 3 is used in the game where the winning combination of the small role 1 and the small role 3 is overlapped. First, the combination of symbols corresponding to the small role 1 is stopped on the active line. If the combination of symbols corresponding to the small role 1 cannot be stopped on the active line, the combination of symbols corresponding to the small role 3 is enabled next. This is a stop position determination table 65 in which the stop position of the reel 31 is determined so as to stop at the line. When the symbol combination corresponding to the small combination 3 cannot be stopped on the effective line, the stop position of the reel 31 is determined so that the symbol combination corresponding to any combination is not stopped on the effective line.

  The small winning combination 1 priority small winning combination 1 / small winning combination 3 is used in the normal probability game. Therefore, as shown in FIG. 4, when the small combination 1 wins, eight payouts are made, and when the small combination 1 does not win and the small combination 3 wins, eight payouts are also made.

  In addition, the small winning combination 3 priority winning combination 1 and small winning combination 3 table is used in a game in which the winning combination of small winning combination 1 and small winning combination 3 is first performed. First, the combination of symbols corresponding to small winning combination 3 is stopped on the active line. When the combination of symbols corresponding to the small role 3 cannot be stopped on the active line, the combination of symbols corresponding to the small role 1 is activated next. This is a stop position determination table 65 in which the stop position of the reel 31 is determined so as to stop at the line. When the symbol combination corresponding to the small combination 1 cannot be stopped on the effective line, the stop position of the reel 31 is determined so that the combination of symbols corresponding to any combination is not stopped on the effective line.

This small combination 3 priority small combination 1 / small combination 3 winning table is used in the high probability games X and Y. Therefore, as shown in FIG. 4, in the high-probability game X, when the small role 3 wins, 12 payouts are made, and when the small role 3 wins without the small role 3 winning, 5 payouts are made. .
On the other hand, in the high-probability game Y, when the small role 3 wins, one payout is made, and when the small role 1 wins without the small role 3 winning, one payout is also made.

In addition, when winning a small role or replay in an internal game of a special role, the winning of the winning role (small role or replay) in the game is given priority and the winning role cannot be won Next, the stop position determination table 65 in which the stop position of the reel 31 is determined so that the combination of symbols corresponding to the special combination carrying over the winning is stopped on the effective line is used.
However, the present invention is not limited to this, and it is also possible to perform control so that a special combination that has won a prize is given priority.

  Furthermore, the non-winning table is used when all the winning flags 63a are off (that is, at the time of non-winning of a combination in a non-internal middle game or a special game), and a combination of symbols corresponding to any combination is valid. The combination of symbols when the reel 31 is stopped is determined so as not to stop at the line. Therefore, the non-winning table is not used inside the special role.

Next, the relationship between the symbol arrangement of the reels 31 and stop control will be described.
As shown in FIG. 2, in all the reels 31, “Bell” and “RP” symbols are arranged at intervals of 5 symbols or less. As a result, the reel control means 64 can always stop the “bell” or “RP” symbol on the desired effective line regardless of which moment the reel 31 is positioned and the stop switch 42 is operated. . Therefore, at the time of winning the small role 3 and replay, it is always possible to win these roles.

  On the other hand, with respect to each symbol of “red 7”, “blue 7”, “BAR”, “watermelon”, and “cherry” of the left reel 31, at least one interval is arranged exceeding 5 symbols. As a result, when 1BBA, 1BBB, RB, small role 1 and small role 2 are won, if the stop switch 42 is not operated at the timing when the symbol corresponding to the winning combination stops on the active line, the symbol corresponding to the winning combination The combination of does not stop on the active line.

Further, in the case where the winning combination of the small part 1 and the small part 3 is given priority and the winning of the small part 1 is given priority and the small part 1 does not win, the small part 3 always wins. There will be no non-winning prizes.
Furthermore, in the present embodiment, when the winning combination of the small part 1 and the small part 3 is given priority and the winning of the small part 3 is given priority, the small part 3 always wins. There is no case of not winning.

Returning to FIG.
The stop symbol determination means 66 determines whether or not the symbol combination of the reel 31 stopped on the effective line matches the symbol combination corresponding to any combination when the reel 31 is stopped. The stop symbol determination means 66 determines a symbol on the effective line by detecting, for example, an angle or the number of steps when the motor 32 is stopped.
However, when the stop switch 42 is operated and the stop position is determined using the stop position determination table 65, the stop symbol determination means 66 determines the stop symbol regardless of whether or not the reel 31 has stopped. It is possible.

  The payout means 67 determines that the combination of symbols stopped on the active line when the reel 31 is stopped matches the combination of symbols corresponding to any of the combinations by the stop symbol determination unit 66 and the winning combination is won. In addition, a predetermined number of medals are paid out to the player in accordance with the winning combination, or processing such as credit addition is performed.

The special game control means 68 controls the start of the special game, the progress of the game during the special game, and the end of the special game of the present embodiment.
When the combination of symbols corresponding to 1BBA is stopped on the active line during the normal game, 1BBA is won and the special game control means 68 controls to start the 1BBA game from the next game.
In the 1BBA game, the lottery of the combination is performed using the above-described combination lottery table 62D. As a result, during the 1BBA game, the winning probability of the small role 3 is increased.

Further, in the present embodiment, as a condition for ending the 1BBA game, the number of medals paid out during the 1BBA game is set to be a predetermined number (200 in this embodiment) or more.
For this reason, the special game control means 68 counts the number of medals paid out during the 1BBA game, keeps updating the number of medals paid out for each game, and the counted number of paid-outs exceeds a predetermined number. When it is determined, it is determined that the end condition of the 1BBA game is satisfied.

Also, when the combination of symbols corresponding to 1BBB is stopped on the active line during the normal game, 1BBB is won and the special game control means 68 controls to start the 1BBB game from the next game.
In this embodiment, the end condition for the 1BBB game is set such that the number of medals paid out during the 1BBB game is equal to or greater than a predetermined number (400 in this embodiment).
For this reason, the special game control means 68 counts the number of medals paid out during the 1BBB game, keeps updating the number of medals paid out for each game, and the counted number of paid-outs becomes 400 or more. When it is determined, it is determined that the end condition of the 1BBB game is satisfied.

Similarly, when the symbol combination corresponding to the RB stops on the active line during the normal game, the RB is won, and the special game control means 68 controls to start the RB game from the next game.
In this embodiment, the RB game end condition is set such that the number of medals paid out during the RB game is equal to or greater than a predetermined number (100 in this embodiment).
Therefore, the special game control means 68 counts the number of medals paid out during the RB game, keeps updating the number of medals paid out for each game, and the counted number of paid-outs becomes 100 or more. When it is determined, it is determined that the RB game end condition is satisfied.

The gaming state control means 69 is a means for controlling transition between each gaming state provided in the present embodiment.
FIG. 9 is a diagram for explaining the transition between the game states.
First, when any special combination wins during any normal game, the game state control means 69 controls to shift to 1BBA game, 1BBB game or RB game according to the special combination won.

After the end of the 1BBA game, the game state control means 69 controls the game state from the next game to shift to the high probability game and the RT game. This RT game is continued for 50 games, and from the 51st game, it is set to a non-RT game although it is a high probability game.
On the other hand, after the end of the 1BBB game or the RB game, the game state control means 69 controls to shift the game state from the next game to the normal probability game (non-RT game).

Further, the game state control means 69 includes a high probability flag 69a for determining whether or not the game is a high probability game. The high probability flag 69a is a flag that is turned on during a high probability game and turned off during a normal probability game.
Furthermore, the game state control means 69 includes an RT flag 69b for determining whether or not the game is an RT game. The RT flag 69b is a flag that is turned on during the RT game and turned off during the non-RT game.

Therefore, after the end of the 1BBA game, since it is a high probability game and an RT game, both the high probability flag 69a and the RT flag 69b are turned on. Also, after the 51st game, the high probability flag 69a remains on, but the RT flag 69b turns off.
When the game state control means 69 shifts to the high probability game, the game state control means 69 continues to count the number of games, and controls to turn off the RT flag 69b at the end of the game when the count value becomes “50”.
Furthermore, after the end of the 1BBB game or the RB game, since it is a normal probability game and a non-RT game, both the high probability flag 69a and the RT flag 69b are turned off.

In addition, the gaming state when the power is turned on is set as follows.
First, when the power of the slot machine 10 is turned on without operating the setting change switch 44 or the like, the gaming state control means 69 controls to set the gaming state to the gaming state before the power is turned off.

On the other hand, when the power is turned off in the high probability game and the high probability release switch 44a is turned on when the setting change switch 44 is operated and the slot machine 10 is turned on, the game state control means 69 Is controlled to be set to the normal probability game.
Furthermore, when the RT game is turned off, the RT release switch 44b is turned on when the setting change switch 44 is operated, and the slot machine 10 is turned on, the gaming state control means 69 sets the gaming state to non-RT. Control to set in the game.

  As described above, at the store where the slot machine 10 is installed, the game state at the time of closing is maintained as it is for the next day, or when the store is closed with high probability game or RT game, the next day starts from normal probability game or non-RT game. Is possible.

Further, the game control means 50 performs control so as to regulate the number of medals inserted in one game according to the game state.
First, during normal probability games and special games (when the high probability flag 69a is off), the number of inserted medals is restricted to three (set so that one or two games cannot be played).
On the other hand, when the high probability flag 69a is on, the number of inserted medals is restricted to one or two (set so that the game cannot be performed with three).

Then, when the game is started with the number of inserted medals being 2, the game becomes a high-probability game X, and the part lottery means 61 performs the part lottery using the part lottery table 62B.
On the other hand, when the game is started with one medal inserted, the game becomes a high probability game Y, and the winning lottery means 61 performs the winning lottery using the winning lottery table 62C.

Next, the relationship between the bet operation and the inserted number in this embodiment will be described. FIG. 10 is a diagram showing the relationship between the betting operation and the number of medals inserted.
As described above, in the present embodiment, the normal probability game can be played only by inserting three cards, and cannot be played by one or two cards.
On the other hand, a high-probability game can be played with one or two cards inserted, and cannot be played with three cards inserted.

In FIG. 10, when the replay is not won in the previous game in the normal probability game, when the 1-bet switch 40a is operated, a process of setting the bet number to “+1” is performed. Further, when one medal is inserted, a process of setting the bet number to “+1” is performed (however, only when the number of bets before the medal insertion is 0 to 2).
Further, when the max bet switch 40b is operated, three bets are set.
On the other hand, when a replay is won in the previous game and three medals have already been automatically inserted, even if the 1 bet switch 40a and the max bet switch 40b are operated, the operation is ignored. In addition, the insertion of medals is ignored (the inserted medals are returned).

  On the other hand, when the replay is a non-winning game in the previous game with a high probability game, one bet is set when the 1-bet switch 40a is operated. When the max bet switch 40b is operated, two bets are set. Furthermore, when one medal is inserted, a process of setting the number of bets to “+1” is performed (provided that the number of bets before the medal is inserted is 0 or 1).

On the other hand, if the replay is won in the previous game and one or two medals have already been automatically inserted, if one bet switch 40a is operated, one bet is set, and the maximum bet switch 40b is set. If operated, two bets are set.
For example, as a result of performing the previous game by inserting one piece, when the replay wins, one piece is automatically inserted. When the 1-bet switch 40a is operated, one bet remains (substantially, the operation of the 1-bet switch 40a is invalidated), but when the max-bet switch 40b is operated, 2 sheets are left. Changed to bet.
Similarly, as a result of performing the previous game by inserting two cards, when the replay wins, two cards are automatically inserted. When the 1-bet switch 40a is operated, the bet is changed to 1-bet. When the max bet switch 40b is operated, two bets remain (substantially, the operation of the max bet switch 40b is invalidated).

Next, the flow of the betting process will be described based on the flowchart.
FIG. 11 is a flowchart showing the flow of bet processing in the present embodiment. 12 to 16 are flowcharts branched from the flowchart of FIG.
In the following flowchart, a non-game state flag, a replay flag A, and a replay flag B are provided.
The non-game state flag is a flag that is turned on at the end of the game (after the payout process based on a winning combination is completed) and turned off when the start switch 41 is operated. is there.

The replay flag A is a flag that is turned on when a replay is won and turned off after an automatic insertion of medals for the next game (automatic betting) is performed.
Furthermore, the replay flag B is a flag that is turned on when a replay is won and a medal is automatically inserted, and turned off when the start switch 41 is operated.
Furthermore, the start switch permission flag is a flag that is turned on when the operation of the start switch 41 can be accepted.
That is, the flow is “replay winning → replay flag A ON → medal automatic insertion (automatic bet) → replay flag A OFF, replay flag B ON → start switch 41 ON → replay flag B OFF”.
Further, although not shown in FIG. 1, the settlement button is a switch operated when receiving a payout of medals electrically stored in the slot machine 10 when the player finishes the game or the like.

In step S11 of FIG. 11, the game control means 50 first continues to determine whether or not the non-game state flag is on. This is because the bet processing operation is not accepted when it is not on, that is, during the game. When it is determined that the non-game state flag is on, the process proceeds to step S12.
In step S12, it is determined whether or not the replay flag A is on. When it is determined that it is on, the process proceeds to step S21 and subsequent steps in FIG. 12, and when it is determined that it is not on, the process proceeds to step S13.
In step S13, it is determined whether the settlement button has been operated. When it is determined that the checkout button has been operated, the process proceeds to step S31 and subsequent steps in FIG. 13, and when it is determined that the checkout button has not been operated, the process proceeds to step S14.

In step S14, it is determined whether or not the 1-bet switch 40a has been operated. When it is determined that the 1-bet switch 40a has been operated, the process proceeds to step S41 and subsequent steps in FIG. 14, and when it is determined that the 1-bet switch 40a has not been operated, the process proceeds to step S15.
In the next step S15, it is determined whether or not the max bet switch 40b has been operated. When it is determined that the max bet switch 40b has been operated, the process proceeds to step S61 and subsequent steps in FIG. 15, and when it is determined that the max bet switch 40b has not been operated, the process proceeds to step S16.

  In the next step S16, it is determined whether or not the start switch 41 has been operated. When it is determined that the start switch 41 has been operated, the process proceeds to step S81 and subsequent steps in FIG. 16, and when it is determined that the start switch 41 has not been operated, this flowchart ends (returns to step S11 and the process is resumed).

When the process proceeds from step S12 to step S21 (at the time of replay winning) in FIG. 12, the game control means 50 determines whether or not the current gaming state is a normal probability game. When it is determined that the normal probability game is being performed, the process proceeds to step S22, and when it is determined that the normal probability game is not being performed (high probability game is being performed), the process proceeds to step S25.
Here, in the above embodiment, the normal probability game is always set to be a non-RT game. On the other hand, in the flowchart of FIG. 12, when the game shifts to the normal probability game after the end of the 1BBB game, it is an RT game up to the 50th game, and the game is performed with one medal insertion number. Shows an example of a non-RT game in which the game is performed with the number of inserted medals set to 3 (two-dot chain line portion in FIG. 12).

  As in the above embodiment, when the normal probability game is uniformly a non-RT game (the number of inserted medals is 3), control proceeds to step S24 if “Yes” in step S21. If the first 50 games of the normal probability game are RT games, it is determined in step S22 whether or not the previous game was an RT game. That is, it is determined whether or not the 50th game has been completed in the previous game (whether or not the 51st game in the game). If it is determined that the previous game is not an RT game, the process proceeds to step S24, the bet number “3” in the previous game is automatically inserted, and the process proceeds to step S26.

On the other hand, if it is determined in step S22 that the previous game is an RT game, the process proceeds to step S23, in which a bet number 3 different from the previous game is automatically inserted, and the process proceeds to step S26. Specifically, as a result of playing a game with a single medal insertion number in the 50th game of RT games, when winning and winning a replay, three coins are automatically inserted as the number of medals for the 51st game.
On the other hand, when it is determined in step S21 that the game is not in the normal probability game (in the high probability game) and the process proceeds to step S25, one or two bets corresponding to the previous game are automatically inserted. Then, the process proceeds to step S26.

  In step S26, the start switch permission flag is turned on. In the next step S27, the replay flag A is turned off and the replay flag B is turned on. And it returns to the flowchart of FIG.

When the process proceeds from step S13 in FIG. 11 to step S31 in FIG. 13 (when the settlement button is operated), the game control means 50 determines whether or not the current bet number is “1” or more. When it is determined that the number is “1” or more, the process proceeds to step S32, and when it is determined that it is not “1” or more, the process proceeds to step S35.
In step S32, it is determined whether or not the replay flag B is off. When it is determined that it is off, the process proceeds to step S33, and when it is determined that it is not off, the process proceeds to step S35.

  In step S33, the game control means 50 (payout means 67) controls the hopper to be driven so as to pay out medals of the current bet number from the hopper. Then, the process proceeds to step S34, the start switch permission flag is turned off, and the process returns to the flowchart of FIG.

On the other hand, when proceeding from step S31 or step S32 to step S35, the game control means 50 determines whether or not the number of credits (the number of stored medals) is “1” or more. When it is determined that the number is “1” or more, the process proceeds to step S36, and control is performed so that the number of medals corresponding to the number of credits is paid out from the hopper hopper. And it returns to the flowchart of FIG.
On the other hand, when it is determined in step S35 that the number of credits is not “1” or more, the process proceeds to step S37, the operation of the settlement button (in step S13 in FIG. 11) is invalidated, and the process returns to the flowchart in FIG.
Although not shown in the flowchart, at the time of processing in step S33, the number of credits is determined, and when the number of credits is “1” or more, medals of the number of credits are paid out together with the number of bets.

When the process proceeds from step S14 of FIG. 11 to step S41 of FIG. 14 (when the 1-bet switch 40a is operated), the game control means 50 determines whether or not the game is a normal probability game. When it is determined that the game is a normal probability game, the process proceeds to step S42, and when it is determined that the game is not a normal probability game (a high probability game), the process proceeds to step S47.
In step S42, it is determined whether or not the current number of credits is “1” or more. When it is determined that it is “1” or more, the process proceeds to step S43, and when it is determined that it is not “1” or more, the process proceeds to step S55.

  In step S43, it is determined whether or not the current bet number is less than “3”. When it is determined that it is less than “3”, the process proceeds to step S44, and when it is determined that it is not less than “3”, the process proceeds to step S55.

In step S44, a process of adding “1” to the current bet number is performed. For example, if the bet count up to that time is “2”, the bet count is set to “3”.
In the next step S45, it is determined whether or not the number of bets at this point is “3”. When it is determined that the game is “3”, the game can be started. Therefore, the process proceeds to step S46, the start switch permission flag is turned on, and the process returns to the flowchart of FIG. On the other hand, when it is determined in step S45 that the bet number is not “3”, the process returns to the flowchart of FIG. 11 without turning on the start switch permission flag.

When it is determined in step S41 that the game is not a normal probability game and the process proceeds to step S47, it is determined whether or not the current bet number is “1”. When it is determined that it is not “1”, the process proceeds to step S48, and when it is determined that it is “1”, the process proceeds to step S55.
In step S48, it is determined whether or not the current sum of the bet number and the credit number is “0” (that is, whether the bet number is “0” and the number of whalelets is “0”).
When it is determined that the total value is not “0”, the process proceeds to step S49, and when it is determined that it is “0”, the process proceeds to step S55.

In step S49, it is determined whether or not the current bet number is “2”. When it is determined that the bet number is not “2”, the process proceeds to step S50. When it is determined that the bet number is “2”, the process proceeds to step S52.
In step S50, the number of bets is set to “1”. In step S51, it is determined whether the start switch permission flag is ON. If it is determined to be on, the flow returns to the flowchart of FIG. On the other hand, when it is determined that it is not ON, the process proceeds to step S46.

If it is determined in step S49 that the bet number is “2” and the process proceeds to step S52, it is determined whether or not the replay flag B is ON. When it is determined that it is on, the process proceeds to step S50, and when it is determined that it is not on, the process proceeds to step S53.
In step S53, it is determined whether the number of credits is “50” (maximum value). If it is determined that the number of credits is not “50”, the process proceeds to step S54, and a process of adding “1” to the number of whalelets is performed. Then, the process proceeds to step S50. On the other hand, when it is determined that the number of credits is “50”, the process proceeds to step S55.

  When the process proceeds from step S42, step S43, step S47, step S48, or step S53 to step S55, the operation of the 1-bet switch 40a is invalidated. And it returns to the flowchart of FIG.

When the process proceeds from step S15 in FIG. 11 to step S61 in FIG. 15 (when the max bet switch 40b is operated), the game control means 50 determines whether or not the game is a normal probability game. When it is determined that the game is a normal probability game, the process proceeds to step S62, and when it is determined that the game is not a normal probability game (a high probability game), the process proceeds to step S68.
In step S62, it is determined whether the current number of credits is “1” or more. When it is determined that it is “1” or more, the process proceeds to step S63, and when it is determined that it is not “1” or more, the process proceeds to step S75.

  In step S63, it is determined whether or not the current bet number is less than “3”. When it is determined that it is less than “3”, the process proceeds to step S64, and when it is determined that it is not less than “3”, the process proceeds to step S75.

In step S64, it is determined whether or not the current sum of the bet number and the credit number is “3” or more. When it is determined that the total value is “3” or more, the process proceeds to step S65. When it is determined that the total value is not “3”, the process proceeds to step S67.
In step S67, a process of betting all credits is performed. And it returns to the flowchart of FIG. On the other hand, in step S65, a process of setting the number of bets to “3” is performed. In step S66, the start switch permission flag is turned on, and the process returns to the flowchart of FIG.

If it is determined in step S61 that the game is not a normal probability game and the process proceeds to step S68, it is determined whether or not the current bet number is “2”. When it is determined that it is not “2”, the process proceeds to step S69, and when it is determined that it is “2”, the process proceeds to step S75.
In step S69, it is determined whether or not the current sum of the bet number and the credit number is “2” or more. When it is determined that the total value is not “2” or more, the process proceeds to step S70, and when it is determined that the total value is “2” or more, the process proceeds to step S75.

In step S70, it is determined whether or not the current bet number is “1”. When it is determined that the number of bets is not “1”, the process proceeds to step S71. When it is determined that the bet number is “1”, the process proceeds to step S73.
In step S71, a process of setting the bet number to “2” is performed. In step S72, it is determined whether the start switch permission flag is ON. If it is determined to be on, the flow returns to the flowchart of FIG. On the other hand, when it is determined that it is not ON, the process proceeds to step S66.

When it is determined in step S70 that the bet number is “1” and the process proceeds to step S73, it is determined whether or not the replay flag B is ON. When it is determined that it is on, the process proceeds to step S71, and when it is determined that it is not on, the process proceeds to step S74.
In step S74, it is determined whether the number of credits is “1” or more. When it is determined that the number of credits is “1” or more, the process proceeds to step S71. On the other hand, when it is determined that the number of credits is not “1” or more, the process proceeds to step S75.

  When the process proceeds from step S62, step S63, step S68, step S69, or step S74 to step S75, the operation of the max bet switch 40b is invalidated. And it returns to the flowchart of FIG.

  When the process proceeds from step S16 in FIG. 11 to step S81 in FIG. 16 (when the start switch 41 is operated), the hand lottery means 61 determines the bet number and the gaming state at the current time (normal probability game, high probability game, non-RT game, RT A predetermined combination lottery table 62 is selected according to the game, and a combination of lotteries is performed based on the combination lottery table 62. In step S82, the replay flag B is turned off.

In the next step S83, the reel control means 64 continues to determine whether or not the wait time corresponding to the number of bets has elapsed. That is, whether 4.1 seconds have elapsed in normal probability games and special games, whether 3.5 seconds have elapsed in high probability games X, and 1.7 seconds have elapsed in high probability games Y Determine whether.
When it is determined that the time has elapsed, the process proceeds to step S84, and the reel control means 64 starts to rotate the reel 31. In step S85, the timer 64a starts measuring from the time when the start switch 41 is operated. And it returns to the flowchart of FIG.

Returning to FIG.
In FIG. 1, the game control unit 50 controls the effect control unit 70 to transmit various types of information. Information to be transmitted includes information indicating that a medal has been inserted, information indicating that the start switch 41 has been operated (rotation of the reel 31 has been started), information on the lottery result of the combination, and operation of the stop switch 42. Information on the fact that the reel 31 has been stopped, information on the stop position of each reel 31 (information on symbols and combinations of symbols stopped on the active line), information on the payout of medals, information on the gaming state, etc. It is done.

In FIG. 1, the effect control means 70 controls the output of effects from the lamp 21, the speaker 22, and the image display device 23.
The effect pattern storage means 71 of the effect control means 70 stores a plurality of types of effect patterns. Then, the effect pattern selecting means 72 of the effect control means 70 performs a lottery using a software random number after the winning lottery is performed by the winning lottery means 61 at the start of the game, etc., according to the game state. Any one of the production patterns corresponding to the lottery result is selected.

In addition, a plurality of types of production patterns are provided according to the winning combination. For example, a plurality of types of effect patterns are provided for each special role winning, small role winning, replay winning, non-winning, and the like.
As for the production pattern, as to the progress of the game, at what timing (when the start switch 41 is operated, when each stop switch 42 is operated, etc.) what kind of production is output (how the lamp 21 is lit) And what kind of sound is output from the speaker 22, what kind of image is displayed on the image display device 23, etc.).
Then, the effect control means 70 controls to output an effect from the effect output device at a predetermined timing according to the selected effect pattern.

  In the slot machine 10 having the above configuration, in the normal probability game, three medals can be inserted by operating the max bet switch 40b. When the 1-bet switch 40a is operated, the number of bets is “+1”. However, the game cannot be started unless 3 cards are inserted.

On the other hand, in the high probability game, the bet number becomes “1” when the 1-bet switch 40a is operated, and the bet number becomes “2” when the max-bet switch 40b is operated. Therefore, in the high-probability game, even if the max bet switch 40b is operated, the number of bets does not become “3”, and it is not possible to play a game by inserting three cards.
Further, in the high probability game, in the next game at the time of replay winning, the number of bets automatically inserted can be changed by operating the 1 bet switch 40a or the max bet switch 40b.

In the normal probability game, 1BBA that shifts to a high probability game after the end of the special game (1BBA game) and 1BBB that shifts to the normal probability game after the end of the special game (1BBB game) are drawn.
As shown in FIG. 7, the winning probability of 1BBA: the winning probability of 1BBB is set to about 1: 2. Therefore, in the normal probability game, when 1BB is won, after the end of the 1BB game, the game shifts to a high probability game with a probability of about 1/3 and shifts to a normal probability game with a probability of about 2/3.

When a transition is made to a high-probability game, according to the player's intention, a high-probability game X is obtained if a game is played with the insertion of two medals, and a high-probability game Y is achieved if a game is played with the insertion of one medal. The high-probability games X and Y have different player advantages (1BB winning probability, etc.).
Both high probability games X and Y are RT games for the first 50 games. However, as shown in FIG. 6, in the high probability game X, the winning probability of replay is 1/5, but in the high probability game Y, the winning probability is further increased to 1 / 1.5.

In the high-probability game X, as shown in FIG. 7, the winning probability of 1BBA is set higher than the winning probability of 1BBB. That is, the high probability game continuation rate is high. For this reason, a player who desires another high-probability game after winning 1BB selects the high-probability game X.
On the other hand, in the high probability game Y, as shown in FIG. 7, the winning probability of 1BBB is set higher than the winning probability of 1BBA. That is, the high probability game ends, but the winning probability of 1BBB with a large number of paid-out medals is high. Therefore, when 1BB is won next time, the player selects the high-probability game Y for a player who wants to end the game after the end of the 1BB game (a player who has no game time or just before closing the hall). Will be.

  In particular, in the high probability game X, the winning probability of 1BBA is 1/44 to 1/38, while in the high probability game Y, the winning probability of 1BBB is 1/22 to 1/19. It is set higher than the winning probability of X 1BBA. For this reason, it can transfer to 1BB game earlier.

The 1BBA game ends with a payout number of 200, but since the 1BBB game has a payout number of 400, the player who gives priority to the 1BBB win is not disadvantageous.
As described above, the high probability game Y is more advantageous when the number of games is small, and the high probability game X is more advantageous when the number of games is large.

In other words, it is assumed that a game in which the maximum number of medals that can be earned is obtained by always winning the winning combination in the game in a state where the setting value that determines the payout rate of the slot machine is constant is assumed to be a virtual game. .
At this time, the payout rate when the virtual game is played N1 times (for example, 50 games) with the number of inserted medals is included (including the payout rate when the special game is won and won in the special role and the special game is played. .) Is E1, and when the virtual game is played N1 times with 2 medal insertions, the payout rate is E2,
E2 <E1
Is set to

  Specifically, if a high-probability game Y is played with one medal inserted number, the winning probability of 1 BBB for shifting to a 1BBB game with a medal payout number of 400 is high probability game X with two medal inserted numbers Is set higher than the winning probability of 1BBA for shifting to a 1BBA game where the number of medals paid out is 200. For this reason, when the number of games is small (for example, several tens of games), the high probability game Y is performed when the high probability game Y is performed with one medal inserted number and the high probability game X is performed with two medal inserted numbers. It will be higher than the appearance rate.

On the other hand, when the virtual game is played N2 (N2> N1) times (for example, 500 games) with one medal inserted number, the payout rate is E3, and the virtual game is played N2 times with two medal inserted number When the rate of appearance is E4,
E4> E3
Is set to

  Specifically, if a high-probability game X is played with two medals inserted, the winning probability of 1BBA for shifting to a 1BBA game for shifting to a high-probability game is set higher than the winning probability of 1BBB. For this reason, in a large number of games (for example, several hundreds of games), when the high-probability game X is performed with two medals inserted, the high-probability game Y is performed with one medals inserted. It will be higher than the appearance rate.

  Further, while the high probability game X wait time is 3.5 seconds, the high probability game Y wait time is set to 1.7 seconds. For this reason, in the same time, the high-probability game Y can digest more games, and accordingly, the time until winning 1BB can be shortened.

The “wait time” is provided for the following purpose.
The current “Enforcement Regulations of the Wind Management Law” prohibits gaming machines that are “substantially intriguing”. As an example, a standard of “a gaming machine having a performance capable of playing a game using a number of medals exceeding the number corresponding to a gaming fee of approximately 400 yen per minute” is provided.
In this case, when the minimum game time for one game is set to 4.1 seconds, when the game is digested in the shortest time, a maximum of 14 games can be played in one minute.

And in order to limit consumption within 400 yen per minute, it is necessary to limit it to about 12 games per minute, so at a rate of twice per minute, that is, once every seven games, In addition, there is a “replay”, that is, “replay” in which there is no payout.
For this reason, a re-game (re-playing role, replay) is introduced at a rate of 2 in 14.6 games, that is, a winning probability of 1 / 7.3, and there is no insertion or payout.
Therefore, if the winning probability of replay is set to 1 / 7.3 and the shortest time (wait time) of one game is set to 4.1 seconds, it is possible to generally comply with “within 400 yen per minute”.

  However, when the number of inserted medals is set to one or two, the number of IN is reduced as compared with the case of three inserted medals, so the wait time can be shortened accordingly. Further, if the replay winning probability is set to a value exceeding 1 / 7.3, the number of replay winning / winning games increases accordingly, so the number of games per minute (other than the replay winning) can be reduced.

For the reasons described above, in this embodiment, in the high-probability games X and Y in which the number of inserted medals is one or two (three is not a game), even if the wait time is less than 4.1 seconds, it is almost the case. You can comply with “within 400 yen per minute”.
It should be noted that the wait time can be set to “0” as long as it can generally comply with “within 400 yen per minute”.

Specifically, when the number of inserted medals is 3, the maximum inserted amount per minute is 878 yen. When the replay winning probability is 1 / 7.3, the number of 1-minute replay winnings is 2 (= 60 yen). When the base is set to 40%, it becomes 878 yen × 0.4 = 351.2 yen, which is generally within 400 yen.
Accordingly, by increasing the replay winning probability, reducing the number of inserted medals, and lowering the medal lending fee, the medal insertion speed is lowered. Therefore, the wait time can be shortened by the following equation.

M = (1-0.4722) * n * k * {60 / t * (1-Pr)} <= 400
M: Expected value of input amount n: Rental fee for one medal (20 yen or less)
k: Number of inserted medals t: Wait time Pr: Replay winning probability When calculated from the above formula, the settable wait time is 1.37 seconds when the number of inserted medals is 1, and the number of inserted medals is 2. Time is 2.73 seconds.

Further, as shown in FIG. 6, in both the normal probability game and the high probability games X and Y, the overlapping winning probability of the small combination 1 and the small combination 3 is set to 1/7.
However, in the normal probability game, when winning the small role 1 and the small role 3, the winning of the small role 1 is given priority, and the payout number is 8 (see FIG. 4). Note that the number of payouts is also 8 when the small role 3 is won.

On the other hand, in the high-probability game X, when winning the small combination 1 and the small combination 3, the winning of the small combination 3 is given priority, and the payout number is 12. On the other hand, the payout number at the time of winning the small role 1 is five.
In the high-probability game Y, when winning the small role 1 and the small role 3, the winning of the small role 3 is given priority, and the payout number is one. Note that the number of payouts is also one at the time of winning the small role 1.
Therefore, the number of payouts for the small winning combination of the small combination 1 and the small combination 3 is higher in the high probability game X than in the high probability game Y.

As mentioned above, although embodiment of this invention was described, this invention is not limited to embodiment mentioned above, The following various deformation | transformation are possible.
(1) The production control means 70 may be provided with a time measuring means, and the closing time may be set on the hall side. Then, during the high probability game, in consideration of the closing time, it may be controlled so as to notify the player of which one of the medal insertion number is advantageous, or which one is advantageous.

  (2) During a non-game, the menu screen may be displayed as an image by a predetermined operation, and the game end scheduled time (or game continuation scheduled time from the current time) may be input therein. The effect control means 70 is controlled based on the input time so as to notify the player of which one of the medal inserted number is advantageous during the high probability game. May be.

  (3) If the day's business ends during high-probability and RT games, that is, if the game ends in RT game and the setting is changed on the hall side, the replay winning probability and wait time will be The number of RT games may be continued (from the start of RT games until 50 games are reached). However, in this case, only the winning probability of the special combination may be set to be the same as the normal probability game.

(4) In the above embodiment, the non-RT game is set for the normal probability game, the RT game is set up to the 50th game in the high probability game, and the non-RT game is set after the 51st game.
However, the present invention is not limited to this. For example, in a normal probability game, an RT game may be set up to a predetermined number of games, and a non-RT game may be set after the predetermined number of games.
In the high probability game, the RT game may be continued until the special combination is won or won.

(5) In the present embodiment, when the power is turned off with a high probability game, when the high probability release switch 44a is turned on when the setting change switch 44 is operated and the slot machine 10 is turned on, the gaming state is set to the normal probability. Set to play.
However, the present invention is not limited to this, and even if the gaming state before the setting change is a high probability game (the high probability flag 69a is on), the normal probability game (the high probability flag 69a is off) after the setting is changed. It is also possible.
In this case, in order to prevent the player from easily knowing whether or not the setting has been changed, the following method can be used.
First, the effect mode when the high probability game (high probability flag 69a is on) and the RT game (RT flag 69b is on) is set to effect A (for example, the background is night during image display).
Then, when only the power is turned off / on without changing the setting (the high probability flag 69a remains on and the RT flag 69b remains on), the effect mode is effect B (for example, during image display) , Set the background to evening).
On the other hand, when the setting is changed and the game state is changed from the high probability game to the normal probability game (the high probability flag 69a is OFF and the RT flag 69b is ON), the effect mode is set to effect B as well. To do.
That is, control is performed so as to switch to effect B when the power is turned off regardless of whether the setting is changed. In this way, it is possible to prevent the presence or absence of the setting change from being known.

  (6) In the normal probability game, the RT game is executed first, and when the predetermined number of games is reached, the game is set to shift to the non-RT game from the next game, and the replay is won in the last game of the RT game. In this case, as shown in step S23 of FIG. 12, three medals may be automatically inserted for the next game. For example, the automatic number of medals maintains the previous game, but the combination lottery table About 62, you may make it use the thing at the time of non-RT game.

  (7) In the high-probability game Y in which the number of inserted medals is one, the payout number at the time of winning the small role 1 and the small role 3 is set to one. Here, the small play 1 or the small combination 3 and the replay may be won in duplicate, and the replay may be preferentially won at the time of the duplicate win. Even if the replay is preferentially won, the number of automatically inserted medals is one, so there is no disadvantage to the player.

  (8) In the normal probability game and the high probability game, the maximum number of moving symbols when the reel 31 is stopped is set to be within 4 symbols and set to the same value. However, the present invention is not limited to this, and in high-probability games, control for reducing the maximum number of moving symbols (for example, one symbol) may be performed. In this case, a stop position determination table 65 for high probability games (with the maximum number of movement symbols changed) may be provided for each winning combination.

(9) The winning probability and the number of payouts in each game state shown in the above embodiment are merely examples, and are not limited thereto.
In the high probability game, the winning probability and the number of payouts may be set so that the payout rate (excluding the special game based on the special game winning) is higher than that in the normal probability game. However, even for high-probability games, the payout rate (excluding special games) is set to less than 100%.
