Description

  The present invention relates to a slot machine that can select any one of a plurality of game types having different game contents by a predetermined operation of a player.

  There are various types of game contents depending on the type of slot machine. For example, the frequency of winning a special role (a role for shifting to a special game that is advantageous to the player) is set low, but once you win a special role, you can expect a lot of medals. Machines and, on the contrary, the frequency of winning special roles is set relatively high, but even if you win special roles, you cannot expect to earn so many medals, It is a slot machine of a type in which a specific game advantageous to the player is set apart from winning.

  Thus, since there are slot machines with various game contents today, it is common for a player to play a game with a slot machine with game contents that suits his / her preference. However, in this case, depending on the game content, there is a slot machine that can only be accepted by a specific player and the operating rate becomes extremely low.

  Here, whether or not the game content is preferred or not depends on the player, so it is extremely difficult to make the game content preferred by all players. In addition, the game content is limited only by mounting the game content preferred by many players, and there is a problem that the player is easily bored.

By the way, a slot machine that can select an effect pattern desired by a player from a plurality of types of effect patterns provided in advance has been known (for example, see Patent Document 1). In Patent Document 1, in a slot machine capable of outputting a plurality of types of effects, a player can select a desired effect type, and when any one of the effect types is selected by the player. It is disclosed that control is performed so as to output the type of the selected effect. Thereby, the player can select the type of production he likes.
The aim of the invention disclosed in Patent Document 1 is to provide a slot machine that can be accepted by many players by allowing the player to select an effect that the player likes without limiting the contents of the effect. .

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of the front surface showing the entire slot machine 10 in the present embodiment. FIG. 2 is a front view illustrating the inside of the base portion 11 with the front mask portion 12 of the slot machine 10 opened in FIG.
As shown in FIGS. 1 and 2, the housing of the slot machine 10 includes a base portion 11 and a front mask portion 12 attached to the front surface of the base portion 11.

The base body 11 is formed in a box shape having a front surface opened by assembling wood and the like. Inside the base portion 11, as shown in FIG. 2, a medal payout device 102 including a power supply unit 101 and a hopper for storing medals is provided at a lower portion.
A support plate 103 is provided above the power supply unit 101 and the medal payout device 102, and the image display device 50 is mounted on the support plate 103.

On the other hand, the front mask portion 12 is attached to the base portion 11 so as to be openable and closable so as to cover the front surface of the base portion 11.
As shown in FIG. 1, the front mask portion 12 has a start switch 41, a stop switch 42, a bet switch 45, a medal slot 43, a medal tray 44, and the like on the front side (player side). . A transparent image display window 12b is provided above the start switch 41 or the stop switch 42 and from the vicinity of the center portion of the front mask portion 12 to the upper portion thereof. The front surface (image display surface) of the image display device 50 arranged in the base body 11 can be seen through from the image display window 12b.

Further, as shown in FIG. 1, the upper portion of the front mask portion 20, particularly in this embodiment, the side away from the start switch 41 and the stop switch 42 with respect to the image display window 12b (image display area) (the image display window 12b). The reel symbol display window 12a is provided at a position spaced apart from the image display window 12b by a predetermined distance so as not to overlap the image display window 12b.
As shown in FIG. 2, the reel unit 30 is disposed on the back side of the front mask portion 12 behind the area where the reel symbol display window 12a is formed together with the sub control board 108 and the like.

  In this embodiment, the reel unit 30 includes three ring-shaped reels arranged side by side (hereinafter, when the entire three reels 31 are indicated, the reels 31 are referred to as a group of reels 31). In addition, a motor 32 (not shown) is connected to the rotation center of the reel 31, and the rotation of the reel 31 is controlled by the drive control of the motor 32. Furthermore, a back lamp 33 (see FIG. 1) for illuminating one symbol from behind is fixed to the inner periphery of each reel 31.

  The sub-control board 108 disposed behind the reel unit 30 is a board for controlling effects during the game, such as sound output, lighting of lamps, display of effect images by the image display device 50, and the like. And a CPU for performing calculations, a ROM for storing presentation programs and presentation data, a RAM for temporarily storing each data, and the like. Note that a main control board 104 to be described later performs overall control of the entire game, but the sub-control board 108 is a board belonging to the lower level of the main control board 104, and is a control board in charge of overall control of the production. is there.

  The sub control board 108 and the main control board 104 are electrically connected by a harness (not shown). Thereby, the main control board 104 is configured to transmit an effect execution command or the like to the sub control board 108.

Furthermore, each reel 31 is affixed with a reel tape on which a plurality of types of symbols (such as symbols constituting a role) are printed.
Then, the reel symbol display window 12a of the front mask portion 12 is arranged so that one symbol of each reel 31 can be seen.

Therefore, a total of three symbols of the reel 31 group can be seen through the reel symbol display window 12a of the front mask portion 12. In FIG. 1, the back lamps 33 on the inner circumference of each reel 31 are indicated by broken-line circles, but the symbols positioned in front of the back lamps 33 can be seen through the reel symbol display window 12a. It corresponds to.
As shown in FIG. 1, in this embodiment, one horizontal line in which three symbols are lined up, which can be seen from the reel symbol display window 12a, is a symbol line when the reel 31 is stopped. The symbol combination line L for forming a combination of Further, when a medal is inserted by the player, this symbol combination line L is an effective line (a line to be determined whether or not the symbol combination corresponds to any combination when the reel 31 is stopped). Set to

  In the present embodiment, the number of the symbol combination lines L is one based on the fact that each reel 31 is arranged so that one symbol can be seen from the reel symbol display window 12a. However, the number of the symbol combination lines L can be increased, for example, when the reels 31 are arranged so that a plurality of symbols that are continuous in the vertical direction can be seen.

Next, feature points of the reel 31 in the present embodiment will be described.
In this embodiment, the reel 31 is formed smaller than a conventional general reel. Accordingly, the area of the reel symbol display window 12a is formed smaller than the area of the conventional display window.

Here, conventionally, the relationship between the display area of the symbol on the reel displaying the game result and the display area of the effect output device is usually smaller in the display area of the effect output device.
What is formed in this way is that the game result is determined by the combination of symbols when the reel (which corresponds to the reel 31 of the present embodiment) is stopped, and is determined by the display content of the effect output device. Because it is not something. In other words, the effect output device wins the game or the pre-game combination until the game result is determined (at least one reel is rotating) or after the game result is determined (after all reels are stopped). This is because it is a device that informs the extent of the possibility and has an auxiliary role in the progress of the game.

However, in the slot machine 10 of the present embodiment, what is the center of the game is not the combination of the symbols of the reels 31 but the content (effect image) displayed by the image display device 50.
Then, as shown in FIG. 1, the image display window 12b is formed larger than the reel symbol display window 12a (the image display window 12b is larger than the reel symbol display window 12a in both vertical and horizontal lengths), and An image display window 12b for displaying an image by the image display device 50 is disposed above the operation switch 40, and a reel symbol display window 12a is disposed on the side away from the image display window 12b with respect to the start switch 41 and the stop switch 42. doing.
In other words, the image display window 12b is arranged between the reel symbol display window 12a and the start switch 41 and the like when viewed from the front side.

  With this configuration, the image display window 12b is located at the approximate center of the slot machine when viewed from the front side. Therefore, the image display window 12b is most easily seen when the player is playing a game, and can easily enter the field of view beyond the reel 31. In particular, since the reel symbol display window 12a is arranged at a certain distance from the image display window 12b so as not to overlap the image display window 12b, the player can directly view the reel symbol display window 12a in the field of view. It becomes difficult to enter. Thereby, a game can be advanced centering on the effect image displayed on the image display window 12b.

  Further, the image display device 50 is provided with a game related information display area 12c. The game-related information display area 12c refers to a display area other than the image display window 12b in the image display device 50, and displays various effects such as characters and announcements, as well as information display indicating a game state and winning symbols. This is a display area for displaying instructions indicating combinations, displaying the number of credits and inserted coins for medals, and displaying background decorations for decorative display of game machine image images. Various displays based on the progress of the game are displayed. This is an area that can be performed.

  Conventionally, the reel stop control is performed so that when a winning combination is made, the stop switch 42 is used so that the player can relatively easily stop the combination of symbols corresponding to the winning combination on the active line. A certain number of symbols are controlled to be movable until the reel actually stops after being operated. On the other hand, after the stop switch 42 is operated, the time from when the stop switch 42 is turned on until the reel stops is usually set to 190 ms or less so that the reel does not stop unnaturally. Furthermore, the rotation speed of the reel is set not to exceed 80 rotations per minute so that the symbols on the reel can be generally identified during the rotation of the reel.

Considering the above, conventionally, for example, the number of symbols on the reel is 21, and the maximum number of symbols to be moved from when the stop switch 42 is detected until the reel stops is the moment when the stop switch 42 is detected. It is set to 5 symbols including the symbol located at.
On the other hand, in this embodiment, the maximum number of moving symbols of the reel 31 is set to 3 symbols.
For example, when the number of symbols of the reel 31 is 11, when the same stop control as that of the conventional reel is performed, the maximum number of symbols that can be moved becomes two symbols. As a result, the total number of symbol combinations when the reel 31 is stopped or the symbol arrangement of the reel 31 is likely to be restricted.

  For this reason, in this embodiment, while the reel 31 is formed small, a sufficient maximum number of moving symbols of the reel 31 when the stop control according to the conventional reel is performed is ensured. In particular, in the present embodiment, the number of symbols on the reel 31 is set to 13, so that the stop control of the reel 31 conforms to the conventional reel, and the maximum number of symbols to be moved on the reel 31 is set to three symbols.

Note that if the rotation speed of the reel 31 is increased, the maximum number of moving symbols of the reel 31 can be set larger. However, if the rotation speed of the reel is increased, the distinguishability of symbols on the reel 31 is deteriorated, which is not preferable.
Therefore, in the present embodiment, the rotation speed of the reel 31 is controlled to be about 78.13 rpm (one round time is about 768 ms). Thereby, it is possible to achieve harmony with the conventional general reel rotation speed such that the rotation speed of the reel does not exceed 80 rotations per minute.

In this embodiment, the image display device 50 is a video slot reel image (reel image is displayed in a planar shape in accordance with the rotation and stop operation of the reel unit 30 in each game. (Moved from the top to the bottom)) is displayed as an effect image.

FIG. 3 is a plan view showing the symbol arrangement of the reel image displayed by the image display device 50. FIG. 3A shows a symbol array corresponding to a game type A, which will be described later, and FIG. 3B shows a symbol array corresponding to a game type B. FIG. ) Shows a symbol array corresponding to the game type C. This will be described later.
As shown in FIG. 3, three reel images of left, middle, and right are provided as display images, and the three reel images of left, middle, and right are stopped according to the operation of the stop switch 42, respectively. The left reel image is stopped and displayed in response to the operation of the left stop switch 42, the middle reel image is stopped and displayed in response to the operation of the middle stop switch 42, and the right stop switch 42 is operated. The right reel image is stopped and displayed).
Note that the symbol group of each of the left, middle and right reel images is composed of 21 symbols, and images are displayed so that the top and bottom symbols in FIG. 3 are continuous. That is, among the 21 symbols, the reel image is rotated when the lowermost symbol in FIG. 3 is the 0th symbol and the uppermost symbol is the 20th symbol. Are moved and displayed so that 21 symbols circulate such as 0th, 1st,..., 19th, 20th, 0th, 1st,.
3 is stored in display symbol pattern storage means 83a described later, and is read out when display control of the reel image is performed.

  When all the reel images are stopped, the three symbols that are continuous in the vertical direction are stopped and displayed so as to be displayed in the image display window 12b for each reel image. In the present embodiment, the symbols are displayed in a 3 × 3 matrix form by three reel images. Furthermore, in this state, in the same manner as in the conventional 5-line type slot machine, a total of five lines including three lines in the horizontal upper stage, middle stage, and lower stage and diagonal lines in the lower right direction and the lower left direction are reel images. This is the symbol combination line.

Next, control of the slot machine 10 will be described. FIG. 4 is a block diagram showing an outline of control of the slot machine 10 according to the present embodiment.
(Game control means, main control means, sub-control means)
The game control means 60 of the slot machine 10 is means for overall control of the entire slot machine 10 including the progress and effects of the game of the slot machine 10, such as lottery of a combination, reel 31 control, and medal payout at the time of winning. Main control means 60a for controlling the progress of the game, and sub-control means 60b for controlling the output of the performance. The main control means 60a is composed of a CPU, ROM, RAM and the like mounted on the main control board 104 described above. The sub-control means 60b is composed of a CPU, ROM, RAM, and the like mounted on the above-described sub-control board 108.

(Bet switch, start switch, stop switch)
A start switch 41, a stop switch 42, and a bet switch 45 are electrically connected to the input side (left side in FIG. 4) of the main control means 60a.

The start switch 41 is a switch operated by the player when starting the reel 31.
Further, three stop switches 42 are provided corresponding to the three reels 31 and are switches operated by the player when the corresponding reels 31 are stopped.
Furthermore, the bet switch 45 is a switch that is operated when the player inserts a stored medal when the game is shifted to the next game, and the active line is activated by the operation.

(Motor, reel)
A motor 32 connected to each reel 31 of the reel unit 30 for controlling the driving of the reels 31 is electrically connected to the output side (right side in FIG. 4) of the main control means 60a.
When the start switch 41 is operated, a signal generated at that time is input to the main control means 60a. When receiving this signal, the main control means 60a controls to rotate all the motors 32. As the reel 31 is rotated by the motor 32 in this manner, the symbols on the reel 31 are moved and displayed in the vertical direction within the reel symbol display window 12a at a predetermined speed.

  Further, when the main control means 60a receives a signal indicating that the start switch 41 has been operated, the main control means 60a controls to start the reels 31 as described above, but further provides a signal indicating that the start switch 41 has been operated. It transmits to the sub-control means 60b.

  Furthermore, when the stop switch 42 is operated, a signal generated at that time is input to the main control means 60a. When receiving this signal, the main control means 60a controls the motor 32 corresponding to the stop switch 42 to perform the stop control of the reel 31.

(Lamp, speaker, image display device)
The output side (right side in FIG. 4) of the sub-control means 60b is electrically connected to effect output devices such as the image display device 50, the speaker 22, and the lamp 23 controlled by the sub-control means 60b.

The speaker 22 outputs a predetermined sound when a predetermined condition is satisfied so as to perform various effects during the game. In this embodiment, as shown in FIG.1 and FIG.2, it is provided in the both right and left sides of the reel symbol display window 12a seeing from the front side.
The lamps 23 are effects lamps for the slot machine 10 and light up in predetermined patterns when predetermined conditions are satisfied. The lamp 23 is a back lamp arranged on the inner peripheral side of each reel 31 of the reel unit 30 described above, or is arranged at the upper front of the casing of the slot machine 10 (not shown), and blinks when winning a winning combination. An upper lamp and a side lamp are included.

  Then, the sub-control unit 60b turns on the image display device 50 and the lamp 21 based on the fact that a signal indicating that the start switch 41 and the stop switch 42 are operated is transmitted from the main control unit 60a. The sound output from the speaker 22 is controlled.

In a normal game, the player inserts a medal from the medal insertion slot 43 or operates the bet switch 45 to enable the symbol combination line (set as an effective line). When the start switch 41 is turned on, all the reels 31 are started.
Next, the player stops the rotation of each reel 31 by turning on each stop switch 42. When all the reels 31 are stopped, when the combination of symbols of the reels 31 on the active line matches a predetermined combination of symbols of a certain combination and the winning combination of that combination is won, Payout etc. are performed.

  In the present embodiment, when the start switch 41 is turned on, the image display device 50 starts moving display of the reel image. Further, when each stop switch 42 is turned on, the image display device 50 stops and displays the reel image corresponding to the stop switch 42 (during movement display).

(Game type)
The slot machine 10 according to the present embodiment includes a plurality of types (three types in the present embodiment) of game types having different game contents. In the slot machine 10 according to the present embodiment, the player can select any one of the plurality of game types by a predetermined operation of the player. The game type selection method will be described later.

Here, the three kinds of game types in the present embodiment mean a game type A, a game type B, and a game type C, each of which has a different medal acquisition number expected value in a specific game period.
The game type A is a so-called normal game type. For example, in addition to a special game, a notification game that is advantageous to the player (a game in which information for winning the winning combination is notified to the player), etc. The game is not set.
The game type B is a game that is controlled to execute a notification game when a predetermined condition is satisfied during a normal game.
Furthermore, the game type C is a game that is controlled so that a notification game is executed during a special game.

  Here, the game type A, the game type B, and the game type C are all the combinations that are selected by the combination lottery means 61 during the normal game, such as BB, RB, small combination 1, small combination 2, small combination 3, And a replay. Further, the winning probabilities of these combinations are also set to be the same winning probabilities except for replay (see FIGS. 5 and 6).

  On the other hand, with respect to the game type A, the game type B and the game type C are controlled such that the notification game is executed under a predetermined condition as described above. Therefore, the game type B and the game type C have a higher medal acquisition expected value in a specific game period than the game type A.

  However, for all game types, the theoretical value of the payout rate is set to be almost the same, and if you look at a specific game period, there will be a difference in the expected number of medals depending on the game type, but the long-term game period Is set so that there is no difference in expected value of the number of medals obtained between game types (details will be described later). Therefore, only a specific game type is not particularly advantageous or disadvantageous for the player, and each game type has only a different game content.

  In the present embodiment, the game type A, the game type B, and the game type C are all subjected to special combination non-winning control that does not stop the combination of symbols corresponding to the special combination on the active line. Then, when a predetermined condition is satisfied, special combination winning control is executed so that the combination of symbols corresponding to the special combination can be stopped on the active line. Therefore, while the special combination non-winning control is being executed, even if the special combination is won, the symbol combination corresponding to the selected special combination does not stop on the active line. However, during this time, since the winning of the special role is carried over, the winning of the special role is stocked by the special role winning carry-over means 66 described later. When the special condition winning control is executed while satisfying the predetermined conditions, the combination of symbols corresponding to the special role that has been won can be stopped on the active line (the special role that has been stocked can be released) State).

(Game control means)
Of the game control means 60, the main control means 60a includes the following means. The sub-control unit 60b includes the following information receiving unit 81 and the like.
The following means in the present embodiment are examples, and the game control means 60 is not limited to the means shown in the present embodiment.

(Role lottery means)
The role lottery means 61 performs a lottery of a role provided in advance. Here, the combination includes a special combination, a small combination, and a replay.

The special role is a role for shifting from a normal game to a special game (a game that can be expected to win medals more than a normal game and is advantageous to the player).
Here, BB is a role that shifts to BB game, which is one of special games, and RB is a role that shifts to RB, which is another special game.
The small combination is a combination in which a predetermined number of medals are paid out, and is set so that the combination of symbols corresponding to the combination and the number of medals to be paid out differ according to the type of the small combination. .
Furthermore, the replay is a replaying role that enables a replaying with maintaining the number of medals (the number of bets) inserted in the game.

FIG. 5 is a diagram showing a combination of a type of a combination, the number of payouts, and a reel image in this embodiment. FIG. 5A shows a type of a combination when the game type A is selected. FIG. 5 (b) is a diagram showing types of roles when game type B is selected, and FIG. 5 (c) is a role when game type C is selected. FIG.
As shown in FIG. 5, in this embodiment, two types of special roles (BB and RB), three types of small roles (small role 1 to small role 3), and replay are provided.
When all the reels 31 are stopped, the combination of symbols corresponding to any of the predetermined combinations stops on the active line, and when a winning combination of the combination is won, a predetermined number of medals are paid out. It is.

  Also, the symbol combinations corresponding to each combination shown in FIG. 5 indicate combinations of symbols of the reel image, and are different from the combination of symbols on the reel 31 corresponding to each combination. Therefore, for example, when winning the BB, the image display window 12b has a combination of “red 7”-“red 7”-“red 7” or “blue 7”-“blue 7”-“blue 7” of the reel image. Although displayed in a stopped state, other predetermined symbol combinations corresponding to BB stop on the effective line in the reel symbol display window 12a.

  When the game type is game type B, in this embodiment, as shown in FIG. 5B, the combination of symbols “BAR”-“BAR”-“BAR” in the reel image is effective during the normal game. By stopping at the line, it is set to shift to a notification game.

  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 of the role lottery means 61 generates random numbers in a predetermined area (for example, 0 to 65535 in decimal notation). The random number extracting means extracts the random number generated by the random number generating means at a predetermined time, in this embodiment, when the start switch 41 is 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, when the extracted random number value belongs to the BB winning area, it is determined as BB winning, and when it belongs to the non-winning area, it is determined as non-winning.

  As shown in FIG. 5, the role lottery means 61 includes, for example, two types of special roles (BB and RB), three types of small roles (small role 1 to small role 3), replay and non-winning in a normal game. The winning combination or non-winning is determined based on the extracted random number value.

(Role drawing table)
The combination lottery table 62 defines the types of combinations to be selected and the winning probability of each combination. The combination lottery table 62 includes a specific combination lottery table 62 for each gaming state (normal game, special game, etc.). Each combination lottery table 62 has a predetermined range of lottery areas. The lottery areas are divided into winning areas and non-winning areas for each combination, and are set to have a predetermined winning probability. Is set to a percentage.

  Here, in this embodiment, as shown in FIG. 6, eight types of lottery tables 62 having different replay winning probabilities are provided. During the normal game, these eight types of lottery table 62 are used properly according to the game type or control state (special role non-winning control or special role winning control).

  Specifically, the normal combination lottery table 62 (the leftmost combination lottery table 62 in FIG. 6) is not in the inside (in the state where the special combination winnings described later are not carried over) during normal games. It is used. Therefore, in the non-internal normal game, the winning lottery means 61 performs lottery using the winning lottery table 62.

  The RT1 combination lottery table 62 is used for the first normal game after the end of the special game. In this embodiment, the first normal game after the end of the special game is a game in which a game type can be selected. Therefore, in the first normal game after the end of the special game in which the game type can be selected, the winning lottery is performed using the RT1 winning lottery table 62. “RT” means a replay time, which means a state in which the winning probability of replay is set to be relatively high.

  Further, the RT2 and RT5 combination lottery table 62 is used when the game type A is selected in the inside (a state where a special combination to be described later is carried over). The RT2 combination lottery table 62 is a combination lottery table 62 used when executing the special combination non-winning control when the game type A is selected. Further, the RT5 combination lottery table 62 is a combination lottery table 62 used when executing the special combination winning control when the game type A is selected. Accordingly, when the game type A is selected, the RT2 combination lottery table 62 is first selected (set). Then, while the special combination non-winning control is being executed, the combination lottery is performed using the combination drawing table 62 of RT2.

  When the game in which the special combination non-winning control is executed is shifted to the game in which the special combination winning control is executed, the RT2 combination lottery table 62 is switched to the RT5 combination lottery table 62. Therefore, at the time of executing the special combination winning control when the game type A is selected, the combination of lottery is performed using the combination lottery table 62 of RT5.

  The RT3 and RT6 role lottery table 62 is used when the game type B is selected in the interior, and the RT3 role lottery table 62 is not used when the game type B is selected. The combination lottery table 62 of RT6 is used when executing the special combination winning control when the game type B is selected.

  Furthermore, the role lottery table 62 for RT4 and RT7 is used when game type C is selected in the interior, and the role lottery table 62 for RT4 is used for special roles when game type C is selected. Used when executing the non-winning control, the RT7 combination lottery table 62 is used when executing the special combination winning control when the game type C is selected.

Thus, in the present embodiment, the different lottery tables 62 are used depending on the game state or game type, and also the control state.
Note that the winning probability of each combination is obtained by dividing the numerical value shown for each combination in FIG. 6 by 65536.
Although not shown, the winning area and the non-winning area of each combination are determined for each number of inserted medals (1 to 3) and for each set value of the payout rate.

  By the way, only when the stop switch 42 is operated in a predetermined operation order, the small role 1 is within the range of the stoppable position of the reel 31 (from when the stop switch 42 is operated until the reel 31 stops. This means within the range of the movement control amount of the reel 31, and in this embodiment, within 3 symbols including the symbol at the moment when the stop switch 42 is operated, in other words, within the range of the stop control time of the reel 31 (stop switch). Means the time from when the terminal 42 is operated to when the reel 31 stops. In this embodiment, the combination of symbols corresponding to the small role 1 is effective within 190 ms from when the stop switch 42 is operated). It is a role controlled to stop (win) the line. In other words, even if the small combination 1 is won, when the stop switch 42 is operated in an operation order other than the predetermined operation order, the combination of symbols corresponding to the small combination 1 does not stop on the active line.

Here, when the stop switches 42 respectively corresponding to the left, middle, and right reels 31 are represented by left, middle, and right, the operation order of the stop switches 42 is “left middle right”, “left and right middle”, There are six types: “middle left and right”, “middle right and left”, “middle right and left”, and “middle right and left”.
In the present embodiment, each of the small combinations 1 is assigned six operation orders equally (1/6).

  For example, as shown in FIG. 6, when the winning probability of the small role 1 is about ½, “left middle right”, “left / right middle”, “middle left / right”, “middle right left”, “right left middle”, and The winning probabilities of each small role 1 of “right middle left” are respectively assigned to 1/12 (1/2 × 1/6). In other words, the winning probability when the small role 1 is regarded as one role (1/2) is ½, and within all the lottery areas of the above-mentioned role lottery table 62, the winning region is ½ for the entire small role 1 , And the 1/2 winning area is divided into six parts, for example, “Operation order is left middle right small role 1”, “Operation order is left and right middle small role 1”,... ing.

In this case, for example, when the “operating order is left middle right small part 1” in the small part 1, and when the stop switch 42 is operated in the order of “left middle right”, the small part 1 is changed. The corresponding symbol combination is controlled to stop on the active line, but when the stop switch 42 is operated in the other five operation orders, the above symbol combination is controlled not to stop on the active line. Is done.
As described above, when winning the small combination 1, the operation order of any one of the stop switches 42 that can be awarded is determined.

  In the present embodiment, the symbols constituting the small role 1 are all arranged on each reel 31 at intervals of 3 symbols or less. Accordingly, the symbols constituting the small combination 1 are arranged on the reel 31 at intervals within the range of the stoptable position of the reel 31 (within 3 symbols including the symbol at the moment when the stop switch 42 is operated). As a result, when winning the winning combination 1, if the operation order of the stop switch 42 matches the operating order of the winning combination 1, the combination of symbols of the winning combination 1 always stops on the active line. Controlled.

  On the other hand, for example, the symbols constituting the small role 1 are separated by an interval (for example, 4 symbols) exceeding the range of the stoptable position of the reel 31 (within 3 symbols including the symbol at the moment when the stop switch 42 is operated). When the small combination 1 is won, the operation order of the stop switch 42 matches the operation order of the selected small combination 1 and the symbols constituting the small combination 1 are stopped on the active line. If the stop switch 42 is not operated at a position where the winning combination can be made, the symbols constituting the winning small combination 1 cannot be stopped on the active line. This means that “the combination of symbols corresponding to the small combination 1 stops at the effective line within the range of the stoppable position of the reel 31”.

(Game type selection means)
The game type selection means 63 is for selecting any one of a plurality of game types by a predetermined operation by the player.

  In this embodiment, the game type selection by the game type selection means 63 is set so that it can be performed in the first normal game after the end of the special game. Therefore, the game type selection means 63 enables the player's predetermined operation for selecting the game type in the first normal game after the end of the special game, and detects this predetermined operation by the player. The game type corresponding to the operation is selected.

  In the first normal game after the end of the special game, the RT1 combination lottery table 62 is selected (set). Therefore, in the first normal game after the end of the special game, the winning lottery is performed using the RT1 winning lottery table 62.

  In addition, the predetermined operation of the player for selecting the game type means an operation of the stop switch 42 in the present embodiment. Therefore, when the operation type of the stop switch 42 is detected during the first normal game after the end of the special game, the game type selection means 63 selects a game type based on this operation.

  Specifically, each of the game type A, the game type B, and the game type C is assigned to the left stop switch 42, the middle stop switch 42, and the right stop switch 42, and the special game ends. In the subsequent first normal game, the game type to be selected is determined by whether the first (first) stop switch 42 is the left stop switch 42, the middle stop switch 42, or the right stop switch 42. Is done. For example, it is assumed that game type A is assigned to the left stop switch 42, game type B is assigned to the middle stop switch 42, and game type C is assigned to the right stop switch 42. Then, in the first normal game after the end of the special game, when the left stop switch 42 is first operated, the game type selection unit 63 selects the game type A corresponding to the left stop switch 42. Similarly, in the game, when the middle stop switch 42 is operated for the first time, the game type selection means 63 selects the game type B corresponding to the middle stop switch 42, and the right stop switch 42 is operated first. When the game type is selected, the game type selection means 63 selects the game type C corresponding to the right stop switch 42.

  When a game type is selected by the game type selection means 63, first, special combination non-winning control is executed. The special combination non-winning control is continued until a predetermined condition is satisfied. When the predetermined condition is satisfied, the control state shifts from the special combination non-winning control to the special combination winning control. It should be noted that the predetermined condition for executing the special prize winning control is that the transition determining means 64 described later is determined to execute the special prize winning control.

(Migration decision means)
The transition determining means 64 determines whether or not to shift the game for which the special combination non-winning control is executed to the game for which the special combination winning control is executed. The number-of-games lottery means 64a and the transition lottery means 64b.

The number-of-games lottery means 64a determines the number of games for executing the special role non-winning control by lottery.
FIG. 7 is a diagram showing a probability table of the number of games of a game for which special role non-winning control determined by the number-of-games lottery means 64a is executed. 7A is a probability table used when the game type A is selected, and FIG. 7B is a probability table used when the game type B is selected. (C) is a probability table used when the game type C is selected.

  In the present embodiment, as shown in FIG. 7, ten predetermined game numbers are set as the number of games, such as 1 to 10 games, 11 to 36 games, 37 to 64 games, and the like. Therefore, any predetermined game number is determined from among the ten predetermined game numbers by lottery by the game number lottery means 64a. When the predetermined number of games is determined, a specific number of games is determined by lottery from the predetermined number of games. For example, when 1 to 10 games are determined as the predetermined number of games, a specific number of games (one of the 1 to 10 games) is further determined by lottery from the 1 to 10 games. The

In addition, different winning probabilities are set for each predetermined number of games, and the winning probabilities are set to be different depending on the game type even for the same predetermined number of games.
For example, the probability of selecting 1 to 10 games is set to 5.0% in FIG. 7A, 2.5% in FIG. 7B, and 1.0% in FIG. 7C. .
Then, as shown in FIGS. 7 (a), 7 (b), and 7 (c), when the game type B or the game type C is selected, than when the game type A is selected, The average number of games is set so as to increase. Therefore, when the game type B or the game type C is selected, the probability that the number of games in which the special game non-winning control is executed increases as compared with the case where the game type A is selected. It means that it becomes difficult to shift to a game in which control is executed.

The reason for this setting is as follows.
Game type B or game type C is set so that the expected number of medals acquired in a specific game period is larger than that of game type A. Therefore, in this specific game period, the game type B or the game type C can win more medals than the game type A. However, the specific game period in which a lot of medals can be obtained is when the game type B satisfies a predetermined condition (notification game) during the normal game, and the game type C In that case, it is during special game (BB game). Therefore, in the game type B or the game type C, by controlling the difficulty of shifting to the game in which the special prize winning control is executed (the rate of shifting), in the long-term gaming period (totally ), It is possible to prevent a difference in the expected medal acquisition number between game types.
This makes it possible to change the game content without causing an advantage or disadvantage between game types.

The lottery of the number of games by the number-of-games lottery means 64 a is performed when the game type is selected by the game type selection means 63.
The lottery of the number of games is performed using, for example, software random numbers.

Next, the transfer lottery means 64b will be described.
The transfer lottery means 64b determines by lottery whether or not the game for executing the special combination non-winning control is shifted to the game for executing the special combination winning control.

In the present embodiment, when the game type is the game type A, the transfer lottery means 64b wins the small role 2 or the small role 3 in the role lottery by the role lottery means 61, or wins any combination. If not, a lottery is performed to determine whether or not to shift to a game in which special prize winning control is executed. Specifically, a 1/3 chance of winning a small role 2, a 1/10 chance of winning a small role 3, or a 1/1 probability when none of the roles were won. It is set to win. Therefore, for example, when the game type is game type A, when the small combination 2 or small combination 3 is won, or when no combination is won, the transfer lottery by the transfer lottery means 64b is performed, , The probability of 1/3, the probability of 1/10, and the probability of 1/1 are determined to shift to a game in which special prize winning control is executed.
In addition, when the game type is the game type B, the transition lottery means 64b is set to win with a probability of 1/4 when winning the small role 2 or with 1/12 probability when winning the small role 3. When the game type is C, winning with a probability of 1/5 when winning a small role, 1/15 when winning a small role, or 1/2 when not winning any role It is set to be.
The lottery by the transfer lottery means 64b is performed using, for example, software random numbers.

  Further, as described above, when the game type B or the game type C is selected, the probability of transition to a game in which special prize winning control is executed is set lower than when the game type A is selected. Yes. That is, when the game type B or the game type C is selected, it is more difficult to shift to a game in which special prize winning control is executed than when the game type A is selected. The reason for this is the same as in the case of the above-mentioned game frequency lottery means 64a, so that the expected medal acquisition number does not differ between game types when viewed over a long game period.

The lottery by the transfer lottery means 64b determines the current game type and control state (special role winning control or special role non-winning control), and performs lottery under a predetermined condition based on the determination result.
In the transfer lottery means 64b, for example, the winning lottery is set to ½, and the lottery is performed using, for example, software random numbers.

  By the way, in this embodiment, when the number of games in which the special combination non-winning control is executed reaches the number of games determined by the game number lottery means 64a as the transition condition to the game in which the special combination winning control is executed, Alternatively, two are provided when it is decided to shift to a game in which special prize winning control is executed by lottery by the shift lottery means 64b. For this reason, while the special combination non-winning control is being executed, when one of the two conditions is satisfied, the game is shifted to a game in which the special combination winning control is executed. Therefore, for example, even if the number of games for which the special role non-winning control is executed does not reach the number of games determined by the game number lottery means 64a, the special prize winning control is executed by lottery by the transfer lottery means 64b. If it is decided to shift to a game, the game shifts to a game in which special prize winning control is executed.

  As described above, the transition determination means 64 (the number-of-games lottery means 64a and the transition lottery means 64b) changes the ease of transition to a game in which special prize winning control is executed or the mechanism for each game type. Thus, it is possible to vary the game contents while making the theoretical value of the payout rate almost the same. Thereby, only a specific game type is not particularly advantageous and disadvantageous, and it is possible to prevent the player from selecting only a specific game type.

(Lottery result storage means)
The lottery result storage unit 65 is for storing the lottery result of the combination by the combination lottery unit 61. The lottery result storage means 65 includes a winning combination flag (BB flag, RB flag, small combination 1 to small combination 3 flag, replay flag, etc.) for every combination. For example, when any combination is won Stores the winning / non-winning of each winning combination by turning on the winning combination flag corresponding to the winning combination. In addition, when a small combination 1 in which the operation order of the stop switch 42 is determined is won, information on the operation order of the stop switch 42 (operation order for winning the winning combination) is also provided together with the winning of the combination. Is memorized.

(Means to carry over special roles)
When the special combination winning means 66 is selected as a special combination in the normal lottery by the combination lottering means 61 during a normal game, the special combination in the game until the combination of symbols corresponding to the special combination stops on the active line. It is controlled to carry over the winning of the game after the next game.

  In the lottery of the role lottery means 61, when winning a small role 1, a small role 2, a small role 3, and a replay, the winning role is valid only in the game, and the winning is held after the next game. It is not overtaken. That is, in a game in which these winning combinations are won, the winning combination flag corresponding to the winning combination is turned on by the lottery result storage means 65, and the winning combination flag is set regardless of whether or not the winning combination is won or not. It is turned off from on at the end of the game.

  On the other hand, when the special combination is won, when the reel 31 is stopped, the winning combination flag of the special combination is turned on until the combination of symbols corresponding to the special combination stops on the active line and the special combination is won. Are maintained and carried over after the next game. Then, when the special combination is won, the winning combination flag of the special combination is turned off.

  Furthermore, in this embodiment, even after winning the special role, the lottery including the special role is performed. For this reason, it is possible to carry over the winning of multiple special roles. In the present embodiment, a plurality of winning combination flags corresponding to the special combination are provided, and each time the special combination is won, the winning combination flag for the special combination is turned on one by one.

  Here, the concept called non-inside and inside is provided in the normal game. Non-inside means a gaming state in which a special role (BB or RB) is not won. On the other hand, “inside” means that the special combination (BB or RB) is won in the game or the game before that, but the combination of symbols corresponding to the won BB or RB is not stopped on the active line. The state of gaming (not winning).

  Furthermore, in the present embodiment, as described above, in the special combination non-winning control in the game type A, the game type B, and the game type C, the combination of symbols corresponding to the special combination is not stopped on the active line. Because it is controlled, even if you win a special role during this time, that win will be carried over. Then, when shifting to the special combination winning control, the combination of symbols corresponding to the special combination that has won the winning combination can be stopped on the active line, and the stocked special combination can be released.

(Reel control means)
The reel control means 67 controls the drive of the motor 32 so as to start the rotation of all the reels 31 when the start switch 41 is operated. Further, the reel control means 67 determines a stop position determination table, which will be described later, based on the winning lottery result by the winning lottery means 61 when the stop switch 42 is operated and the timing when the stop switch 42 is operated. The stop position of the reel 31 corresponding to the stop switch 42 is determined with reference to 67a, and the motor 32 is driven and controlled to stop the reel 31 at the determined position.

  For example, in a game where one of the winning combinations is won, the reel control means 67 controls to stop the reel 31 so that the combination of symbols of the winning combination is stopped on the effective line within the range where the reel 31 can be stopped. At the same time, the reel 31 is controlled to stop so that combinations of symbols other than the winning combination are not stopped on the active line. However, in the case of a winning combination (in this embodiment, a small combination 1) in which the operation order of the stop switch 42 is determined, the condition is that the stop switch 42 is operated in the determined operation order.

Further, the reel control means 67 is controlled so as to execute the special role non-winning control when the special role winning is carried over by the special role winning carry-over means 66 and any game type is selected. At the same time, when it is determined by the transition determining means 64 to shift to the game in which the special prize winning control is executed, the special winning prize control is controlled.
In particular, the reel control means 67 executes the special role non-winning control for the number of games determined by the game number lottery means 64a on the condition that the transfer lottery is not won by the transfer lottery means 64b. When the game for which the control is executed reaches the determined number of games, the special control winning control is executed.

(Stop position determination table)
The stop position determination table 67a determines the stop position of the symbol of the reel 31 from the lottery result of the combination by the combination lottery means 61 and the position of the reel 31 at the moment when the stop switch 42 is operated. The stop position determination table 67a includes a stop position determination table 67a for each winning combination and a stop position determination table 67a at the time of non-winning (when no winning combination is won).

For example, in the stop position determination table 67a used when no winning combination is won, the stopping position of the reel 31 is determined so that the combination of symbols corresponding to any winning combination does not stop on the effective line. Yes.
Further, the stop position determination table 67a used at the time of winning of the combination indicates that the stop position of the reel 31 is within the range where the reel 31 can be stopped so that the combination of symbols corresponding to the winning combination stops on the effective line. It has been established.
Furthermore, the stop position determination table 67a used when the special combination non-winning control is executed determines the stop position of the reel 31 so that the combination of symbols corresponding to the selected special combination does not stop on the effective line. The stop position determination table 67a used when the special combination winning control is executed is such that the stop position of the reel 31 is determined so that the combination of symbols corresponding to the selected special combination can be stopped on the effective line. ing.

  Using the stop position determination table 67a described above, the reel control means 67, when stopping a combination of symbols of any role on the effective line, within the range of the positions where the reel 31 can be stopped, Pull-in control of symbols constituting the combination is performed. That is, if the reel 31 is immediately stopped at the position where the operation of the stop switch 42 is detected, if the symbol related to the role does not stop on the effective line, the reel 31 is moved and controlled during stop control, so that Controls to positively stop the symbols related to.

Further, the reel control means 67 includes the following operation order detection means 67b.
(Operation order detection means)
The operation order detection unit 67b detects the operation order of the stop switch 42 when the small combination 1 is won by the combination lottery by the combination lottery unit 61. The stop switch 42 is provided for each reel 31 (for each of the left, middle, and right reels 31), but the stop switch 42 that is operated first (first) is the left, middle, and right reels 31. Which of the reels 31 corresponds to the stop switch 42 and which of the left, middle and right reels 31 the second operated stop switch 42 corresponds to which of the reels 31 Is detected. When each stop switch 42 is operated, an identification signal is transmitted to the operation order detecting means 67b, and the operation order of the stop switch 42 is detected based on the identification signal.

(Design array data storage means)
The symbol array data storage means 67c stores symbol array data for each of the left, middle, and right reels 31. Here, the “symbol arrangement data” is for each reel 31 and specifies the type of the symbol corresponding to the symbol number. Is used when stopping at the effective line.

  First, when winning the winning combination 1 by the winning lottery means 61, before the stop switch 42 is operated (before the stop control of the reel 31), the reel control means 67 displays the symbol of the winning winning combination 1. A stop position determination table 67a (stop position determination table 67a used when no combination is won during normal game) is selected so as not to stop the combination in the active line. (set.

  When the operation order of the stop switch 42 operated by the player (detected by the operation order detection means 67b) matches the operation order corresponding to the winning small role 1, Instead of using the set stop position determination table 67a, the reel 31 is controlled to stop using the symbol arrangement data so that the symbols constituting the symbol combination corresponding to the small combination 1 are stopped on the effective line.

  For example, it is assumed that the small combination 1 according to the operation order of the stop switch 42 “left middle right” is won. In this case, when the player first operates the stop switch 42 related to the left reel 31, the reel control means 67 uses the symbol arrangement data to stop the symbol corresponding to the small role 1 on the active line. The reel 31 is controlled to stop.

  Here, it is searched for the presence or absence of the symbol of the small role 1 from the symbols located on the effective line at the moment when the player operates the stop switch 42 within the range of the position where the reel 31 can be stopped with respect to the effective line. If the symbol of the small role 1 exists within the range, the symbol is determined as a symbol that stops at the effective line, and the reel 31 is controlled to stop so that the symbol stops at the effective line.

  On the other hand, in the case where the reel control means 67 wins the small role 1 in the role lottery by the role lottery means 61, the operation order of the stop switch 42 operated by the player corresponds to the winning small role 1. When the operation order of the stop switch 42 does not match, the combination of symbols corresponding to any combination is not stopped on the active line by using the already set stop position determination table 67a (without using symbol arrangement data). The reel 31 is controlled to stop (that is, the combination of symbols corresponding to the winning small combination 1 does not stop on the active line).

  When the operation order of the stop switch 42 operated second or third matches the operation order corresponding to the selected small role 1, the operation order of the stop switch 42 operated first (first). Is controlled to stop the reel 31 using the symbol arrangement data only when the operation order corresponding to the winning combination 1 is matched.

  On the other hand, even if the operation order of the stop switch 42 operated second or third matches, if the previous operation order does not match, the stop position determination table 67a is used to One reel 31 is controlled to stop.

  If controlled in this way, the stop control of the reel 31 after the operation order of the stop switch 42 operated by the player does not coincide with the operation order corresponding to the winning small role 1 is uniformly, This can be done using the stop position determination table 67a.

As described above, when winning the small role 1, according to the operation order of the stop switch 42, the stop control using the stop position determination table 67a (the winning small role 1 is not won) or the symbol arrangement data is used. By performing the stop control of the existing symbols, there is no need to provide a stop position determination table 67a for each operation order of the stop switch 42. As a result, the control can be simplified and the data capacity of the stop position determination table 67a can be reduced.
However, it goes without saying that the stop position determination table 67 may be provided in correspondence with the operation order of the stop switch 42.

(Stop symbol discrimination means)
The stop symbol discrimination means 68 discriminates symbols on the reel 31 that have stopped on the active line when the reel 31 is stopped, and whether or not the symbol combination on the effective line matches any symbol combination of any combination. Is to discriminate.
The stop symbol discrimination means 68 discriminates symbols on the effective line by detecting, for example, the angle when the motor 32 is stopped, the number of steps, and the like.

  The stop symbol discriminating means 68 does not discriminate the symbol combination after the reel 31 has actually stopped, but the stop position determination table selected from the position of the reel 31 at the moment when the stop switch 42 is operated. When the stop position of the reel 31 is determined by 67a, it is also possible to determine the combination of symbols that stop on the effective line.

(Winning process means)
The winning symbol processing unit 69 determines that the combination of symbols stopped on the active line when the reel 31 is stopped matches the symbol combination of any of the combinations by the stop symbol determining unit 68, and when the winning combination is won. A predetermined number of medals corresponding to the winning combination is paid out to the player, or credits are added.
When a replay is won, control is performed so that the number of medals inserted in the game is automatically inserted without paying out medals.

(Special game control means)
The special game control means 70 controls the transition from the normal game to the special game (BB game or RB game), the progress of the game during the special game, the transition from the special game to the normal game, and the like.

First, the special game control means 70 shifts from the normal game to the special game on condition that the combination of symbols stopped on the active line matches the combination of symbols of the special combination (BB or RB) and the special combination wins. Control to do.
For example, when a BB winning is made, the normal game is shifted to the BB game, and when the RB winning is made, the normal game is shifted to the RB game. At the time of transition, in order to notify the player that the transition to the special game is to be made, control is performed so as to perform various effects such as lighting of the lamp 23, output of sound from the speaker 22, and image display by the image display device 50.

The special game control means 70 controls the progress of the game during the special game (in the BB game and in the RB game).
The special game control means 70 first starts the first game (general game) in the BB game. This first game is a game in which a predetermined number of medals (for example, 3) are inserted and played in the same manner as in the normal game. It is a transitional role for transitioning to a specific small role and a second game (bonus game). In the first game, the upper limit of the number of games is predetermined as, for example, 30 times. The special game control means 70 continues to count the number of games in the first game.

In the present embodiment, the combination of symbols of the specific small role selected in the first game and the number of medals to be paid out when the combination of symbols stops on the active line are combined with the combination of symbols of the small role 1 (“Bell "-" Bell "-" bell ") and the combination of symbols is set to be the same as the number of medals to be paid out when the combination is stopped on the active line (15). Therefore, in the first game, when the symbol combination of “bell”-“bell”-“bell” stops on the active line, a specific small role is won and 15 medals are paid out. Similarly to the small combination 1, the specific small combination is controlled so that the combination of symbols corresponding to the specific small combination stops on the active line only when the stop switch 42 is operated in a predetermined operation order. It is a role to be played. That is, even if a specific small combination is won, if the stop switch 42 is operated in an operation order other than the predetermined operation order, the combination of symbols corresponding to the specific small combination is controlled so as not to stop on the active line. The
The reel 31 is controlled by the reel control means 67 when the specific small combination is won, which is the same as when the small combination 1 is won, and the selected specific small combination is won according to the operation order of the stop switch 42. Stop control using the stop position determination table 67a not to be performed or symbol stop control using the symbol array data is performed.

Here, when the game type is game type C, in the first game, when a specific small combination is won, the operation order of the stop switch 42 for stopping the combination of symbols corresponding to the specific small combination on the effective line is notified. Is done. Therefore, the player can surely win the selected specific small combination by following this notification content. On the other hand, when the game type is game type A or game type B, the stop switch 42 for stopping the combination of symbols corresponding to the specific small role in the active line even if the specific small role is won in the first game. The operation order is not notified.
Since there are six operation orders of the stop switch 42 as described above, a combination of symbols corresponding to a specific small role is effective when a specific small role is won in a notification game and a game that is not a notification game. There is a 6-fold difference in the probability of stopping (winning) on the line.
Therefore, in the notification game, the number of medals obtained is increased over the game that is not a notification game, which is advantageous for the player.

  The special game control means 70 provides the first game on condition that the combination of symbols stopped on the active line in the first game matches the combination of symbols on the transition role, that is, on the condition that the winning combination of the transition role is a condition. To shift to the second game. When transitioning from the first game to the second game, in order to notify the player of this, the active line with the combination of symbols corresponding to the transition combination is flashed by the lamp 23, or during the first game until then A process of outputting a sound different from that from the speaker 22 is performed.

  In the second game, for example, only one medal can be inserted, and only the effective line in the middle in the horizontal direction is activated, and the combination of symbols of a predetermined role is stopped on this effective line with a high probability of, for example, about 95%. The game is controlled so that a predetermined combination is won. Then, the second game is continued until the number of winning of the predetermined role reaches a specified number (for example, 8 times) or until the number of games reaches a specified number (for example, 12 times). Therefore, the special game control means 70 counts the number of games in the second game and the number of winnings of the predetermined role in order to determine whether or not the second game end condition is satisfied.

  The special game control means 70 ends the second game when the number of games of the second game or the number of winning of the predetermined role reaches the specified number of times, on condition that the BB game end condition is not satisfied, Control is performed to return to the first game again.

  Here, in the BB game, the upper limit of the number of transitions from the first game to the second game is set to a predetermined number (for example, three times). Therefore, at the end of the second game when the specified number of times is reached, control is performed so that the BB game is ended without shifting to the first game again. For this reason, the special game control means 70 counts the number of times of transition from the first game to the second game during the BB game. For example, at the time of the first game during the BB game, a transition role for shifting to the second game wins, and when shifting to the second game, 1 is added to the number of times of transition.

  In the RB game, the second game in the BB game is played as one set, that is, a game in which a predetermined combination is won with a high probability until the specified winning number or the specified number of games is reached. Therefore, the special game control means 70 continues to count the number of winnings or games of a predetermined role in the RB game.

  The special game control means 70 determines whether or not the special game end condition is satisfied during the special game. When it is determined that the special game end condition is satisfied, the special game control means 70 ends the special game and returns to the normal game. To control.

  The special game control means 70, when the special game is a BB game, when the number of games of the first game reaches the specified number of times, or when the number of times of transition from the first game to the second game reaches the specified number of times In the second game, when any one of the number of games or the number of winnings of the predetermined role reaches the specified number, it is determined that the BB game end condition is satisfied. In addition, when the special game is an RB game, the special game control means 70 sets an end condition for the RB game when satisfying any one of the number of winnings of the predetermined role or when the number of games reaches the specified number. It is determined that it is satisfied.

(Information transmission means)
The information transmission means 71 is selected by the game type selection means 63, the lottery result information of the combination by the combination lottery 61, the operation information that the start switch 41 is operated, the operation information that the stop switch 42 is operated, Information on the game type (including information on the set lottery table 62 (including information on RT1 to RT7) and the like) is transmitted to the sub-control means 60b.
In addition, when winning a small combination 1 or a specific small combination by winning combination by the combination lottery means 61, information on the operation order of the stop switch 42 for stopping the combination of symbols of the selected small combination 1 on the effective line is also transmitted. Is done.

Subsequently, each of the game control means 60 on the sub-control means 60b side will be described.
(Information receiving means)
The information receiving unit 81 receives the lottery result information of the combination by the combination lottery unit 61, the operation information that the start switch 41 is operated, and the operation information that the stop switch 42 is operated, which is transmitted by the information transmission unit 71. Information of the game type selected by the game type selection means 63 (including information on the set lottery table 62 (information such as RT1 to RT7) set) is received.
On the side of the sub-control means 60b, based on the received information, the production content is determined, or a predetermined lottery is performed.

(Notification control means)
The notification control means 82 controls whether or not to execute a notification game, execution of the notification game, and the like.

The notification control means 82 determines whether or not to execute a notification game, and determines to execute a normal game (non-notification game) unless the following conditions are satisfied.
First, when the game type B is selected, the notification control means 82 performs a lottery (performed using a software random number or the like) on whether or not to shift to each game notification game during the normal game. When the lottery is won, it is decided to execute the notification game. In this lottery, for example, it is decided to execute the notification game with a probability of 1/500. When the lottery is won, it is decided to execute the notification game, and when it is not won, it is decided to continue the normal game (non-notification game).
When the lottery is won, the reel image display control means 83c, which will be described later, uses the combination of symbols “BAR”-“BAR”-“BAR” in the reel image as shown in FIG. 5B. Control to stop display.
In addition, the number of notification games is set to, for example, 20 games. When a small role 1 is won during the 20 games, the operation order of the stop switch 42 for winning the selected small role 1 is determined. Control to be notified.
In addition, the number of games of the notification game may not be determined in advance, but may be determined by lottery each time (when the notification game is executed).

Secondly, when the game type C is selected, the notification control means 82 is determined to execute the notification game unconditionally during a special game (BB game) or when a specific small role is won. To do. Therefore, when a specific small combination is won during the BB game, the operation order of the stop switch 42 for winning the specific small combination is always notified.
When the game type A is selected, the notification control means 82 does not execute the notification game regardless of whether the game is a normal game or a BB game.

  As described above, the notification control unit 82 determines the current game type based on the game type information transmitted from the main control unit 60a side (information transmission unit 71), and the current game type is the game type B. When the determination is made, a lottery is performed as to whether or not to shift to each game notification game during the normal game. When the lottery is won, control is performed so that the notification game is executed.

  Further, when the notification control means 82 determines that the current game type is the game type C from the game type information and the lottery result information transmitted from the main control means 60a side (information transmission means 71), It is determined whether or not a winning combination has been won. After winning a special combination, a special game is executed. When a specific small combination is won, a notification game is executed.

When it is decided to execute the notification game, the notification control means 82 controls to execute the notification game until the end condition of the notification game is satisfied.
When the notification control unit 82 shifts to the notification game, the combination of lotteries is performed by the combination lottery unit 61 as in the normal game. When winning a small combination 1 or a specific small combination, the information transmission means 71 of the main control means 60a also provides information on the operation order of the stop switch 42 for winning the selected small combination 1 or a specific small combination. At the same time, it is transmitted to the sub-control means 60b. Thereby, when the information receiving means 81 receives the information indicating that the small combination 1 or the specific small combination is won, the information receiving means 81 also receives the information on the operation order of the stop switch 42. The notification control means 82 controls to notify the operation order of the stop switch 42 based on the received operation order information of the stop switch 42.

  Various methods can be used as the notification method. For example, a notification method using the image display device 50 or a notification method using the lamp 23 (in particular, a back lamp installed on the inner peripheral surface side of the reel 31). (For example, a method in which only the reel 31 corresponding to the stop switch 42 to be operated is turned on by the back lamp and the others are turned off).

  As a specific notification method, for example, when the stop switch 42 is operated in the order of left, middle, and right, the combination of symbols corresponding to the selected small combination 1 can be stopped on the active line. An image “left → middle → right” is displayed on the display device 50. The other operation order of the stop switch 42 is left, right, middle order, middle, left, right order, middle, right, left order, right, left, middle order, right, middle, left order. These are also displayed in the same manner.

  As described above, when the notification game is executed, the operation order of the stop switch 42 for winning the selected small combination 1 or the specific small combination is notified when the small combination 1 or the specific small combination is won. If the stop switch 42 is operated according to the notification contents, the symbols constituting the small role 1 or the specific small role are arranged at intervals within 3 symbols as in this embodiment, so that these symbols are always effective. It is possible to stop at the line, and it is always possible to win a small combination 1 or a specific small combination. As a result, during the notification game, the winning rate of the small combination 1 or the specific small combination is increased, so that it is possible to increase the number of acquired medals more than the normal game or more than the first game that is not notified.

(Production control means)
The effect control unit 83 controls the effect produced by the image display device 50, and includes a display symbol pattern storage unit 83a, a display symbol pattern selection unit 83b, and a reel image display control unit 83c described below.

(Display design pattern storage means)
The display symbol pattern storage means 83a stores a plurality of types of display symbol patterns displayed on the reel image. In this embodiment, three types of display symbol patterns are provided corresponding to game types. FIG. 8 shows display symbols corresponding to game type A, FIG. 9 shows display symbols corresponding to game type B, and FIG. 10 shows display symbols corresponding to game type C. Is. 8, 9, and 10, the symbols “red 7”, “blue 7”, “BAR”, “watermelon”, “bell”, “cherry”, and “replay” are shown, respectively. However, even with the same “Red 7”, “Blue 7”, “BAR”, “Watermelon”, “Bell”, “Cherry”, and “Replay” designs, colors and designs vary depending on the game type. Are set differently.

3 (a), 3 (b), and 3 (c) show the symbols of the reel images when game type A, game type B, and game type C are selected as described above. FIG. 3 is a diagram showing the arrangement. Each display image shown in FIG. 8, FIG. 9, and FIG. 10 is displayed on each reel image as shown in FIG. 3 (a), FIG. 3 (b), and FIG. They are arranged in the arrangement shown in c).
Therefore, in the display symbol pattern storage means 83a, for each game type, the above-described display symbols (FIGS. 8, 9, and 10) displayed on the reel image and the symbol arrangement (FIGS. 3A, 3) are displayed. (B) and FIG. 3 (c)) are stored.

(Display pattern pattern selection means)
The display symbol pattern selection unit 83b selects a display symbol pattern from the display symbol pattern storage unit 83a based on the game type selected by the game type selection unit 63.

When the sub-control means 60b (information receiving means 81) receives the game type selection information transmitted from the main control means 60a (information transmitting means 71), the display symbol pattern selecting means 83b is based on the received information. Then, a display symbol pattern is selected from the display symbol pattern storage means 83a.
For example, when the received game type selection information is information indicating that game type A has been selected, a display symbol pattern corresponding to game type A is selected from display symbol pattern storage means 83a. That is, as the display symbol pattern corresponding to the game type A, the symbol arrangement of FIG. 3A configured by the display symbol shown in FIG. 8 is selected. Similarly, for example, when the received game type selection information is information indicating that the game type B has been selected, the game type B consists of the symbol array shown in FIG. 3B configured by the display symbols shown in FIG. Select the display pattern. Furthermore, when the received game type selection information is information indicating that game type C has been selected, a display symbol pattern composed of the symbol arrangement of FIG. 3C configured by the display symbol shown in FIG. Select.

(Reel image display control means)
The reel image display control unit 83c performs control so that the reel image is rotated when the start switch 41 is operated (when the sub-control unit 60b receives information indicating that the start switch 41 has been operated). At the same time, when the stop switch 42 is operated (when the sub-control means 60b receives information indicating that the stop switch 42 has been operated), control is performed so that the reel image corresponding to the stop switch 42 is stopped and displayed. Is. That is, the reel image display control means 83 controls the display of the reel image so as to be interlocked with the rotation operation and the stop operation of the reel 31.

Further, the reel image display control means 83c controls to display the display symbol pattern selected by the display symbol pattern selection means 83b. Therefore, for example, when the game type A is selected, the reel image display control unit 83c displays an image of a display symbol pattern corresponding to the game type A, and the game type is changed from the game type A to the game type B or the game type C. When switched to, the reel image display control means 83c controls to switch the image display to the display symbol pattern corresponding to the game type B or the game type C.
Thus, when the game type is selected, the reel image display control means 83c controls to switch the image display to a display symbol pattern corresponding to the selected game type.

  Furthermore, when the game type B is selected and the reel image display control means 83c is selected for lottery of whether to shift to the notification game during the normal game, “BAR” − “ Control is performed so that the combination of symbols “BAR”-“BAR” is stopped and displayed on the active line.

Furthermore, the reel image display control means 83c, when the special control non-winning control is executed by the reel control means 67, the predetermined reel image group corresponding to the combination of symbols of the special role (BB) of the reel 31 group. In this embodiment, control is performed so that the combination of symbols ("red 7"-"red 7"-"red 7" or "blue 7"-"blue 7"-"blue 7") is not stopped and displayed on the active line. When the special prize winning control is executed by the reel control means 67, a predetermined symbol combination of the reel image group corresponding to the special combination (BB) symbol combination of the reel 31 group can be stopped and displayed on the effective line. To control.
Therefore, when the sub-control means 60b receives the lottery result information, information indicating that the stop switch 42 has been operated, etc., the reel image display control means 83c receives the game type selection information and the control status (special role). The reel image is stopped and displayed based on the information of the non-winning control or special role winning control).

Next, the main control flow in this embodiment will be described based on the flowcharts of FIGS. 11 to 14.
FIG. 11 is a flowchart showing a flow of processing in the main control means 60a (in a state where the winning of the special role is carried over). FIG. 12 is a flowchart subsequent to FIG. 11, and is a flowchart showing a flow of processing after all the reels 31 are stopped. FIG. 13 is a flowchart subsequent to FIG. 11, and is a flowchart showing a flow of processing in a non-internal state (a state in which the special role winning is not carried over). Further, FIG. 14 is a flowchart showing a flow of effect processing in the sub-control means 60b.

  First, in step S1 of FIG. 11, the main control means 60a continues to determine whether or not the start switch 41 has been operated (turned on). If it is determined that the start switch 41 has been turned on, the process proceeds to step S2. When the start switch 41 is turned on, all the reels 31 start to rotate.

  In the next step S 2, it is determined whether or not the special combination winning means 66 has carried over the special combination winning (internal). When it is determined that the inside is inside, the process proceeds to step S3, and when it is determined that the inside is not inside (not inside), the process proceeds to step S50 in FIG.

In step S3, the combination lottery means 61 performs combination drawing using the currently selected combination lottery table 62.
Although omitted in this flowchart, the combination of lotteries is performed by operating the start switch 41.
In next step S4, the information transmitting means 71 transmits the lottery result of the combination to the sub-control means 60b (information receiving means 81).

  In the next step S5, it is determined whether the currently selected combination lottery table 62 is from RT2 to RT4. If the currently selected combination lottery table 62 is any one of RT2 to RT4, the process proceeds to step S6. If it is not any of RT2 to RT4, the process proceeds to step S12.

  In step S6, the transfer lottery means 64b performs a lottery to determine whether or not to shift to special prize winning control according to a predetermined lottery result. That is, when the game type is the game type A or the game type C, the transfer lottery means 64b performs the transfer lottery when winning the small role 2 or the small role 3 or when not winning any of the roles. . Further, when the game type is the game type B, the transfer lottery means 64b performs the transfer lottery when the small combination 2 or the small combination 3 is won.

  In the next step S7, it is determined whether or not the transition lottery in step S6 has been won, that is, whether or not it has been determined to shift to special prize winning control. When it is determined that the transfer lottery has been won, the process proceeds to step S8. When it is determined that the transfer lottery has not been won, the process proceeds to step S9.

  In step S8, since it is determined to win the transition lottery and shift to the special winning prize control, one of the winning lottery tables 62 from RT5 to RT7 used during the special winning prize control is selected (set).

  In the next step S9, the main control means 60a continues to determine whether or not the stop switch 42 has been operated (turned on). When determining that the stop switch 42 has been turned on, the main control means 60a proceeds to step S10.

In step S10, the reel control means 67 performs stop control of the reel 31 in accordance with the set lottery table 62 (any one of RT5 to RT7).
Since the set combination lottery table 62 is any one of RT5 to RT7, the reel control control means 67 controls the reel 31 so that the combination of symbols corresponding to the special combination can be stopped on the effective line. (Special prize winning control).

  In the next step S11, the main control means 60a determines whether or not all the reels 31 are stopped. When it is determined that all the reels 31 are stopped, the process proceeds to step S30 in FIG. 5, and when it is determined that all the reels 31 are not stopped, the process returns to step S9.

  If it is determined in step S5 that the currently selected combination lottery table 62 is neither RT2 nor RT4, the process proceeds to step S12, and whether the currently selected combination lottery table 62 is RT5 to RT7. To determine. If the currently selected combination lottery table 62 is any of RT5 to RT7, the process proceeds to step S9. If it is not any of RT5 to RT7, the process proceeds to step S13.

  In step S13, the main control means 60a continues to determine whether or not the stop switch 42 has been operated (turned on). When it is determined that the stop switch 42 has been turned on, the process proceeds to step S14.

  In step S14, it is determined whether or not the stop switch 42 that has been turned on is the first (first) operation (first operation). When it is determined that the stop switch 42 that has been turned on is operated first, the process proceeds to step S15. When it is determined that the stop switch 42 is not operated first, the process proceeds to step S23.

  In step S15, it is determined whether or not the stop switch 42 operated first is the left stop switch 42. When the first operated stop switch 42 is determined to be the left stop switch 42, the process proceeds to step S16. When it is determined that the first operated stop switch 42 is not the left stop switch 42, the process proceeds to step S18. .

In step S16, the game type selection means 63 selects the game type (game type A in this embodiment) corresponding to the left stop switch. Then, together with the selection of the game type, the RT2 combination lottery table 62 corresponding to the game type A is set.
Further, the information transmitting means 71 transmits information on the selected game type to the sub-control means 60b (information receiving means 81).
In the next step S17, the game number lottery means 64a performs a lottery of the number of games. Then, the process proceeds to step S23.

  If it is determined in step S15 that the first operated stop switch 42 is not the left stop switch 42, the process proceeds to step S18 to determine whether or not the first operated stop switch 42 is the middle stop switch 42. . When it is determined that the first operated stop switch 42 is the middle stop switch 42, the process proceeds to step S19. When it is determined that the first operated stop switch 42 is not the middle stop switch 42, the process proceeds to step S21. .

In step S19, the game type selection means 63 selects the game type (game type B in this embodiment) corresponding to the middle stop switch 42. Then, together with the selection of the game type, the RT3 combination lottery table 62 corresponding to the game type B is set.
Further, the information transmitting means 71 transmits information on the selected game type to the sub-control means 60b (information receiving means 81).
In the next step S20, the game number lottery means 64a draws the number of games. Then, the process proceeds to step S23.

In step S18, when it is determined that the first operated stop switch 42 is not the middle stop switch 42, the process proceeds to step S21, and the game type selection means 63 determines the game type corresponding to the right stop switch 42 (this embodiment). Now, game type C) is selected. Then, together with the selection of the game type, the RT4 combination lottery table 62 corresponding to the game type C is set.
Further, the information transmitting means 71 transmits information on the selected game type to the sub-control means 60b (information receiving means 81).
In the next step S22, the game number lottery means 64a draws the number of games. Then, the process proceeds to step S23.

  Proceeding from step S17, step S20, or step S22 to step S23, the reel control means 67 responds to the set lottery table 62 (RT2, RT3, or RT4), that is, according to the selected game type. The special role non-winning control is executed. Accordingly, the reel control means 67 controls to stop the reel 31 so that the symbol combination corresponding to the special combination does not stop on the effective line.

  In the next step S24, the main control means 60a determines whether or not all the reels 31 are stopped. When it is determined that all the reels 31 are stopped, the process proceeds to step S30 in FIG. 12, and when it is determined that all the reels 31 are not stopped, the process returns to step S13.

  In step S30 of FIG. 12, the stop symbol determination means 68 determines whether or not the combination of symbols corresponding to any combination has stopped on the active line, that is, whether any combination has won a prize. When it is determined that any combination has won, the process proceeds to step S31. When it is determined that any combination has not won, the process proceeds to step S34.

  In step S31, it is determined whether or not the winning combination is replay. When it is determined that the replay has been won, the process proceeds to step S33, and when it is determined that the replay has not been won, the process proceeds to step S32.

  In step S32, it is determined whether or not the winning combination is a small combination (small combination 1, small combination 2, or small combination 3). When it is determined that the small role has been won, the process proceeds to step S33, and when it is determined that the small role has not been won, the process proceeds to step S38.

  If it is determined in step S31 or step S32 that the replay or small role has won, the process proceeds to step S33, and the winning processing means 69 performs a medal payout process. When a small combination wins, a predetermined number of medals are paid out according to the type of small winning combination, but when a replay is won, the number of medals inserted in the game is not paid out. Control to automatically turn on.

  In the next step S34, it is determined whether the combination lottery table 62 used in the current game is from RT2 to RT4. When it is determined that any of the lottery table 62 for RT2 to RT4 is set, the process proceeds to step S35, and when it is determined that any of the lottery table 62 for RT2 to RT4 is not set, this flowchart is executed. The process by is terminated.

In step S35, 1 is added to the number of games G, and the process proceeds to step S36.
In step S36, it is determined whether or not the game count G has reached the game count determined by the game count lottery means 64a. When it is determined that the game number G has reached the game number determined by the game number lottery means 64a, the process proceeds to step S37, and the game number G has not reached the game number determined by the game number lottery means 64a. Is determined, the processing according to this flowchart is terminated.

In step S37, any combination lottery table 62 from RT5 to RT7 is set. That is, based on the fact that the number of games G has reached the number of games determined by the number-of-games lottery means 64a, the game is shifted to a game in which special prize winning control is executed.
The information transmitting means 71 sends sub-control means 60b (information) that information indicating that any of the winning lottery tables 62 from RT5 to RT7 has been set, that is, the game in which the special winning combination winning control is executed is transferred. To the receiving means 81).

  If it is determined in step S32 that the winning combination is not a small combination, the process proceeds to step S38, and it is determined whether or not an RB has been won. If it is determined that the RB has been won, the process proceeds to step S39. If it is determined that the RB has not been won, the process proceeds to step S41.

  If it is determined in step S38 that the RB has won, the process proceeds to step S39, where the special game control means 70 executes the RB game. When the RB game ends, the process proceeds to step S40.

  In step S40, the combination lottery table 62 corresponding to the previous RT is set, and the game number lottery means 64a performs lottery of the number of games. Therefore, the combination lottery table 62 does not change before the RB game and after the RB game. That is, the game type is not changed. These pieces of information are transmitted by the information transmitting unit 71 to the sub-control unit 60b (information receiving unit 81).

  If it is determined in step S38 that the RB has not won, the process proceeds to step S41, and the special game control means 70 executes the BB game. When the BB game ends, the process proceeds to step S42.

  In step S42, the RT1 combination lottery table 62 is set. Therefore, the game shifts to the game type selection game corresponding to the RT1 combination lottery table 62. These pieces of information are transmitted by the information transmitting unit 71 to the sub-control unit 60b (information receiving unit 81).

In step S2 of FIG. 11, when it is not inside, the process proceeds to step S50 of FIG. 13, and the winning lottery means 61 performs the lottery of the winning combination.
Although omitted in this flowchart, the combination of lotteries is performed by operating the start switch 41.
In the next step S51, the information transmitting unit 71 transmits the lottery result of the combination by the combination lottering unit 61 to the sub-control unit 60b (information receiving unit 81).

  In the next step S52, it is determined whether or not BB or RB is won. When it is determined that BB or RB has been won, the process proceeds to step S53, and when it is determined that neither BB nor RB has been won, the process proceeds to step S56.

In step S53, any combination lottery table 62 from RT2 to RT4 is set.
In the next step S54, the information transmission means 71 transmits the information of the set combination lottery table 62, that is, the information of the game type corresponding to the set combination lottery table 62 to the sub-control means 60b (information reception means 81). To do.

In the next step S55, the number-of-games lottery means 64a determines the number of games G for which the special role non-winning control is executed by lottery, and proceeds to step S56.
In step S56, the main control means 60a continues to determine whether or not the stop switch 42 has been operated (turned on). When determining that the stop switch 42 has been turned on, the main control means 60a proceeds to step S57.

In step S57, the reel control means 67 performs stop control of the reel 31.
In the next step S58, the main control means 60a determines whether or not all the reels 31 are stopped. When it is determined that all the reels 31 are stopped, the process proceeds to step S59. When it is determined that all the reels 31 are not stopped, the process returns to step S56.

  In step S59, the stop symbol determination means 68 determines whether or not the combination of symbols corresponding to any combination has stopped on the active line, that is, whether any combination has won. When it is determined that any combination has won, the process proceeds to step S60, and when it is determined that any combination has not won, the processing according to this flowchart is terminated.

  If it is determined in step S59 that any winning combination has been won, the process proceeds to step S60 to determine whether or not the replay has been won. If it is determined that the replay has been won, the process proceeds to step S62. If it is determined that the replay has not been won, the process proceeds to step S61.

  In step S61, it is determined whether or not a small combination (small combination 1, small combination 2, or small combination 3) has won a prize. When it is determined that the small role has been won, the process proceeds to step S62. When it is determined that the small role has not been won, the process proceeds to step S63.

  If it is determined in step S60 or step S61 that a replay or a small combination has won, the process proceeds to step 62, and the winning processing means 69 performs a medal payout process corresponding to the winning combination. When a small combination wins, a predetermined number of medals are paid out according to the type of small winning combination, but when a replay is won, the number of medals inserted in the game is not paid out. Control to automatically turn on.

  If it is determined in step S61 that the winning combination is not a small combination, the process proceeds to step S63, and it is determined whether or not an RB has been won. If it is determined that the RB has been won, the process proceeds to step S64. If it is determined that the RB has not been won, the process proceeds to step S66.

  If it is determined in step S63 that the RB has won, the process proceeds to step S64, and the special game control means 70 executes the RB game. Then, when the RB game ends, the process proceeds to step S65.

  In step S65, the normal time lottery table 62 (the role lottery table 62 used during non-internal normal games) is set. These pieces of information are transmitted to the sub-control unit 60b (information receiving unit 81) by the information transmitting unit 71.

  On the other hand, if it is determined in step S63 that the RB has not won, the process proceeds to step S66, and the special game control means 70 executes the BB game. When the BB game ends, the process proceeds to step S67.

  In step S67, although it is the first normal game after the end of the BB game, since the special combination is not stocked, the normal combination lottery table 62 is set instead of the RT1 combination lottery table 62. These pieces of information are transmitted to the sub-control unit 60b (information receiving unit 81) by the information transmitting unit 71. Note that the game type selection screen may be displayed as an effect, although the game does not shift to a game type selection game by setting the normal combination lottery table 62.

Next, based on the flowchart of FIG. 14, the flow of the effect process in the sub-control means 60b will be described.
In step S <b> 70 of FIG. 14, it continues to determine whether or not the information reception unit 81 has received the lottery result information from the information transmission unit 71. And when it determines with having received lottery result information, it progresses to step S71.

  In step S71, it is determined whether or not the RT3 combination lottery table 62 is set. If it is determined that the RT3 combination lottery table 62 is set, the process proceeds to step S72. If it is determined that the RT3 combination lottery table 62 is not set, the process proceeds to step S81.

  In step S72, it is determined whether a notification (referred to as AT in this flowchart) game is being played. If it is determined that the vehicle is in AT, the process proceeds to step S73. If it is determined that the vehicle is not in AT, the process proceeds to step S77.

  In step S73, the notification control means 82 performs notification according to the lottery result. That is, when the winning combination information of the small combination 1 is received by the lottery result information, information regarding the operation order of the stop switch 42 for stopping the combination of the symbols of the small combination 1 on the effective line is notified.

In the next step S74, 1 is added to the number N of notification games.
In the next step S75, it is determined whether or not the number N of games has reached a predetermined number. When it is determined that the number N of notification games has reached the predetermined number, the process proceeds to step S76, and the AT game is terminated. On the other hand, when it is determined that the number N of notification games has not reached the predetermined number, the process proceeds to step S86.

If it is determined in step S72 that the AT is not in progress, the process proceeds to step S77, and a lottery is performed to determine whether or not to execute the AT according to the lottery result and the set lottery table 62 or the like.
The lottery for determining whether or not to execute AT is when the game type is the game type B, and when winning the small role 2 or the small role 3 by the role lottery means 61, or any combination If you don't win any of them, you will win with 1/3 chance of winning a small role 2 or 1/10 of a small role 3 winning or 1/1 when you want to win any role. Is set as follows.

Then, in step S78, it is determined whether or not a lottery for whether or not to execute AT has been won. If it is determined that the lottery has been won, an AT game is started in step S79. On the other hand, when it is determined that the lottery is not won, the process proceeds to step S80.
In step S80, a predetermined effect according to the lottery result is selected, and the process proceeds to step S86.

  If it is determined in step S71 that the RT3 combination lottery table 62 is not set, the process proceeds to step S81, and it is determined whether the RT1 combination lottery table 62 is set. When it is determined that the RT1 combination lottery table 62 is set, the process proceeds to step S82. When it is determined that the RT1 combination lottery table 62 is not set, the process proceeds to step S85, and the lottery result and the set result are set. An effect is selected according to the role lottery table 62 and the like.

In step S82, the effect at the time of game type selection is output.
In the next step S83, the game type selection information is continuously detected. When the game type selection information is received, the process proceeds to step S84, and the display symbol pattern selection means 83b selects a display symbol pattern corresponding to the selected game type.

  The process proceeds from step S80, step S76, step S84, or step S85 to step S86, and it is determined whether or not the winning information of any combination is received. When the winning information of any combination is received, the process proceeds to step S87. When the winning information of any combination is not received, the process proceeds to step S90.

In step S87, it is determined whether or not the winning information of any combination is BB winning information. When it is determined that the information is BB winning information, the process proceeds to step S88, where an effect process corresponding to the game type corresponding to the RT combination lottery table 62 before winning BB is performed.
On the other hand, when it is determined that the winning information of any of the combinations is not BB winning information, the process proceeds to step S89, and an effect process corresponding to the winning information is performed.

  Proceeding from step S86, step S88, or step S89 to step S90, it is determined whether or not the current game is a game for game type selection (first normal game after the end of the special game). When it is determined that the game is a game for selecting a game type, the process proceeds to step S91. When it is determined that the game is not a game for selecting a game type, the processing according to this flowchart is terminated.

  In step S91, the reel image is switched to a display symbol pattern corresponding to the selected game type. For this reason, the reel image display control means 83c displays an image of the display symbol pattern corresponding to the game type selected by the display symbol pattern selection means 83b.

As mentioned above, although one Embodiment of this invention was described, this invention is not limited to embodiment mentioned above, For example, the following various deformation | transformation is possible.
(1) In the embodiment, as a plurality of types of game types set in the slot machine 10, a game type A in which a notification game is not executed and a notification game is executed when a predetermined condition is satisfied during a normal game. Three game types are provided: a game type B and a game type C in which a notification game is executed during a special game.
However, the game content of the game type and the type of game type are not limited to these, and a game type with a game content different from the above three types of game content may be provided and set in the slot machine 10 The types of game types to be played are not limited to three (three or more game types may be used, and conversely, two game types may be used).

(2) In the embodiment, the display symbol pattern of the reel image (the symbol corresponding to the game type and the symbol array configured by this symbol) is switched according to the selected game type. For example, the game type A In both cases of game type B and game type C, the same display symbol is set, but only the symbol arrangement (the symbol arrangement of each reel image) is switched according to the game type. You may do it. Therefore, in this case, the arrangement (only) of the symbols of the reel image changes depending on the game type.
When the symbol arrangement is switched according to the selected game type, the symbol arrangement pattern storage means storing a plurality of types of symbol arrangement patterns displayed on each reel image and the game type selection means are selected. There is provided a symbol arrangement pattern selecting unit for selecting a symbol arrangement pattern of the reel image from the symbol arrangement pattern storing unit based on the game type. Then, the reel image display control unit 83c controls to display a reel image having the selected symbol arrangement pattern when the predetermined symbol arrangement pattern is selected by the symbol arrangement pattern selection unit.

(3) In the embodiment, the display design of the reel image is switched according to the selected game type, but the design of the display screen of the image display device 50 may be switched in addition to the display design of the reel image. . For example, it is a design change such as a color scheme of the display screen and a background decoration display of the display screen.
Then, when switching the screen design according to the selected game type, the screen design pattern storage means for storing a plurality of screen designs of the display screen of the image display device 50 and the game selected by the game type selection means. Screen design pattern selection means for selecting the screen design of the display screen of the image display device 50 from the screen design pattern storage means based on the type is provided. Then, the reel image display control means 83c controls to display the selected screen design pattern on the display screen of the image display device 50 when a predetermined screen design pattern is selected by the screen design pattern selection means.

(4) In the embodiment, the game type is selected by operating the stop switch 42. However, the selection of the game type is not limited to this. For example, when a game type is selected, a screen for selecting a game type is displayed on the image display device 50, and this screen is displayed. The game type may be selected according to the information from. That is, the reel image display control means 83c switches the display screen of the image display device 50 from the screen displaying the reel image group to the game type selection screen when the player selects the game type. It is.
The game type may be selected by operating a stop switch according to information on the display screen, as in the embodiment, or by providing a switch for game type switching on the display screen. Thus, the game type may be switched (in this case, the display screen is of a touch panel type).

  (5) In the embodiment, the effect reel is displayed on the electrical display means, that is, the image display device 50 as a reel image. However, the effect reel is not limited to the reel image display by the electric display means, and an actual effect reel may be provided.

  (6) In the embodiment, when the number of games for which the special role non-winning control is executed reaches the number of games determined by the game number lottery means 64a, or the special prize winning control is executed by the lottery by the transition lottery means 64b. When either one of the times when it was decided to shift to a game to be satisfied is satisfied, the game is controlled so as to shift from the game in which the special combination non-winning control is executed to the game in which the special combination winning control is executed. That is, in the embodiment, two conditions are set as the transition conditions to the game in which the special prize winning control is executed. However, the present invention is not limited to this, and only one of the conditions may be set. For example, as a condition for shifting to a game in which the special role winning control is executed, only when the number of games in which the special role non-winning control is executed reaches the number of games determined by the game number lottery means 64a, or the special role The transition condition to the game in which the winning control is executed may be performed only when it is determined to shift to the game in which the special prize winning control is executed by the lottery by the transition lottery means 64b.
