Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slot machine capable of shifting to a bonus game which gives a player more advantageous conditions than a normal game under a certain condition after a special game such as a big bonus game is completed. .

[0002]

2. Description of the Related Art In a conventional slot machine, after the end of a special game such as a big bonus game or a regular bonus game, the game returns to the same base game as before the start of the special game, and also, under certain conditions, the game is played more than the base game. There is known a slot machine for shifting to a game with a privilege that gives an advantageous condition to a player. For example, first, as a game with a privilege, first, there is known a game in which a winning probability of a bonus combination, a small combination, or the like is higher than in a normal game. Secondly, at least some reels are not controlled to stop, and a game is played in a state in which a symbol aimed by a player can be stopped on an active line while the reels are rotating. Have been.

[0003] Whether or not to shift to the special game after the end of the special game is determined when the special role for shifting to the special game is won by a lottery inside the slot machine, and also after the end of the special game. Lottery has been performed to determine whether the game is a base game or a bonus game. When the special role is won and the game is shifted to the special game, whether or not to shift to the game with the privilege after the end of the special game has been notified to the player by, for example, the following method.

[0004] As a first example, a plurality of combinations of special combinations are provided, and when a special combination is won by one of the combinations, the game is shifted to a bonus-added game after the end of the special game. It is known that when a special combination is won by one combination of symbols, after the special game is over, the game returns to the normal game without playing the game with the privilege.

[0005] That is, the presence or absence of the transition to the game with the privilege is notified by the combination of the symbols of the winning special combination. Therefore, when the special combination is won, the player can know whether or not to shift to the bonus game after the end of the special game. Also, as a second example,
There is known a game that informs a player whether or not to proceed to a game with a privilege by turning on a lamp or outputting a specific sound at the end of a special game. Therefore, the player cannot know whether or not to shift to the bonus-added game unless the special game ends.

[0006]

However, in the above-described conventional slot machine, it is not determined whether or not to shift to the special bonus game by providing a plurality of special combination of symbols as in the first example. When the combination of the special role symbols stops on the activated line, it is possible to determine whether or not the game has shifted to the bonus game, so that the game content during the special game thereafter has nothing to do with the shift to the game with the bonus. Was.

[0007] Further, when the special game is notified of whether or not to shift to the game with the privilege at the end of the special game, it is not possible to know whether or not to shift to the game with the privilege unless the special game is ended. Therefore, as in the case described above, the game content during the special game is irrelevant to the shift to the bonus game. For this reason, there is a problem that the game content during the special game tends to be monotonous even in the slot machine which enables the shift to the game with the privilege.

[0008] Therefore, the problem to be solved by the present invention is to relate the possibility of shifting to a game with a privilege to a slot machine capable of shifting to a game with a privilege after the end of the special game, in relation to the game content in the special game. By notifying, the game content during the special game is given a sense of tension and expectation.

[0009]

Means for Solving the Problems To solve the above-mentioned problems, the invention of claim 1 provides a role lottery means for performing a lottery of a role, a special role being won by the role lottery means, and a special lottery being selected. Special game transition means for transitioning from the base game to the special game on condition that the combination of stopped symbols matches a predetermined combination of symbols of the special combination, and when the condition for ending the special game is satisfied When the special game is ended and the game shifts to the normal game, or shifts to a game with a benefit that is more advantageous than the normal game under certain conditions, when the special role is won by the role lottery means, A transition game lottery means for performing a lottery to determine whether the game to be shifted to after the end of the special game is a base game or a bonus game, and a result of the lottery of the transition game lottery means, A specific symbol pattern appearance control means for controlling the reels to stop so that the appearance rate of the specific symbol pattern during the special game is higher than when the game is shifted to the base game, when the game is shifted to the indexed game. And characterized in that:

According to a second aspect of the present invention, in the slot machine according to the first aspect, the specific symbol pattern in the specific symbol pattern appearance control means is a combination of specific winning symbols out of a plurality of winning symbol combinations. It is characterized by. According to a third aspect of the present invention, in the slot machine according to the first aspect, the specific symbol pattern in the specific symbol pattern appearance control means is a combination of a first winning symbol among a plurality of winning symbol combinations. The symbol pattern appearance control means increases the appearance rate of the first winning symbol combination when the game is to be shifted to the bonus game, and increases the appearance rate of the second winning symbol combination when the game is to be shifted to the normal game. Is increased.

[0011] The invention of claim 4 is the invention of claims 1 to 3.

In the slot machine according to any one of the above,
The special game shifting means is for shifting from a base game to a general game in a special game. During the general game in the special game, a combination of symbols stopped on an active line is a predetermined combination of shift symbols. A bonus game shifting means for shifting from a general game in a special game to a bonus game on condition that the specific symbol pattern appearance control means includes at least one of a general game in a special game and a bonus game. In this game, the reel is stopped and controlled.

[0013] The invention of claim 6 is the invention of claims 1 to 4.
In the slot machine according to any one of the above,
The special game shifting means is for shifting from the base game to the general game in the special game, and in the general game, a combination of a plurality of shift symbols is provided, and during the general game in the special game, On condition that the combination of the symbols stopped on the activated line matches any one of the predetermined combinations of the plurality of shift symbols,
It is provided with a bonus game shifting means for shifting from a general game during a special game to a bonus game, wherein the specific symbol pattern in the specific symbol pattern appearance control means is a combination of a specific shift symbol among a combination of a plurality of shift symbols. And

Display means for displaying the number of appearances.

[0015]

According to the first aspect of the present invention, the lottery means performs lottery at the start of a game or the like. When a special combination is won in this lottery, the transition game lottery means performs a lottery to determine whether the game after the end of the special game is a bonus-added game or a normal game. Then, when it is decided to shift to the game with privilege, after the end of the special game, the game shifts to a game with privilege in which advantageous conditions are given to the player under certain conditions. The notification of the possibility of shifting to the game with the privilege after the end of the special game is made by stopping the reels by the specific symbol pattern appearance control means during the special game. That is, when shifting to the bonus-added game, the specific symbol pattern appearance control means makes the appearance rate of the specific symbol pattern higher than when shifting to the normal game. Therefore, it is possible to notify the possibility of shifting to the game with the privilege in association with the game content during the special game, and to give the player a sense of tension and expectation during the special game.

In the second aspect of the present invention, the specific symbol pattern is set to a combination of specific winning symbols, and the greater the number of winnings by the combination of the specific winning symbols, the higher the possibility of shifting to the bonus game. Therefore, it is possible to notify the possibility of shifting to the game with the privilege based on the winning frequency of the combination of the specific winning symbols. According to the third aspect of the present invention, if there are many winnings by the combination of the first winning symbols, the possibility of shifting to the game with the privilege increases, and if there are many winnings by the combination of the second winning symbols, the game can shift to the normal game. The nature becomes high. Therefore, it is possible to notify the possibility of the transition to the game with the privilege by the combination of the winning frequency by the combination of the first winning symbols and the winning frequency by the combination of the second winning symbols.

In the fourth aspect of the present invention, when the game is shifted to a bonus-added game, a large number of specific symbol patterns appear on a specific valid line among a plurality of valid lines. Therefore, it is possible to notify the possibility of shifting to the bonus-added game depending on on which activated line the specific symbol pattern frequently appears.

According to the fifth aspect of the present invention, in a special game having a general game and a bonus game, the appearance rate of a specific symbol pattern is increased in at least one of the games. Therefore, the notification of the possibility of shifting to the game with benefits can be expressed more broadly. Claim 6

Is done. Therefore, it is possible to notify the possibility of shifting to the bonus-added game depending on which combination of shift symbols shifts to the bonus game.

In the present invention, the number of appearances of the specific symbol pattern is counted by the appearance number counting means, and the result is displayed on the appearance number display means so as to be visible to the player. Therefore, when notifying the possibility of transition to the game with the privilege based on the number of appearances of the specific symbol pattern, the player can easily predict the possibility of transition by seeing the number displayed on the appearance number display means. can do.

[0020]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing the appearance of an embodiment of the slot machine according to the present invention. In FIG. 1, a front panel 20 is provided on a front portion of a housing of the slot machine 10, and three transparent display windows 21 are provided in the front panel 20. On the other hand, inside the housing and behind the display window 21,
Three reels (turning drums) 31 (not shown) are arranged corresponding to the respective display windows 21, and a predetermined range of the outer peripheral surface of the reel 31 can be seen from the display windows 21.

Each of the reels 31 is formed in a ring shape, and a reel tape on which a plurality of winning symbols (to be described later) are printed is attached to an outer peripheral surface thereof. A motor (to be described later) (stepping) motor 32 is connected to the center of the reel 31, and the reel 31 is rotated by the rotation of the motor 32, and a symbol on the reel 31 is displayed in the display window 21 in a predetermined vertical direction. Move and display at speed. Further, a back lamp (not shown) is arranged inside each reel 31. This back lamp is
A lamp is arranged behind three symbols continuous above and below the reel 31 in the display window 21.
Is formed from a material having a light-transmitting property, and is configured such that the symbols on the reel 31 are illuminated by lighting of the back lamp.

An effective line 22 (22a to 22c) is displayed on a portion of the front panel 20 including the display window 21. The effective line 22 is composed of a middle effective line 22a in the horizontal direction, two upper effective lines 22b in the horizontal direction, and two effective lines 22b in the lower right and lower left directions.
And an effective line 22c. When each reel 31 is stopped, if a combination of specific symbols is stopped on the activated line 22, a winning is achieved, and medals are paid out.

The valid line 22 at the time of the game differs according to the inserted medals. For example, when one medal is inserted, one valid line 22a is used, and when two medals are inserted, three valid lines in the horizontal direction are used. Active lines 22a and 22
b, when three medals are inserted, a total of five effective lines 2 including two oblique effective lines 22c are additionally provided.
2a to 22c. A medal insertion slot 23 is provided on the lower right side of the front panel 20. When a medal is inserted by a player from the medal insertion slot 23, the medal insertion slot 23 is determined by a detection sensor (not shown), and the number of inserted medals is determined. The valid line 22 is accordingly activated, and the valid line lamp 24 is turned on.

FIG. 2 is a diagram showing a symbol arrangement of each reel (left reel, middle reel and right reel) 31. As shown in FIG. On one reel 31, 21 symbols are arranged at equal intervals.
The symbols are "Red 7", "Blue 7", "BAR", "Bell",
It is composed of seven types of “plum”, “cherry” and “replay”, and each reel 31 has a different arrangement. In FIG. 2, the design is represented by characters, unlike the actual design.

In the symbol arrangement of the reel 31, three kinds of symbols of "bell", "plum" and "replay" are:
The other symbols located within at most five intervals, that is, between the symbols are arranged within four. The symbols are arranged in this manner for the following reasons. In a normal slot machine, stop control of the reel 31 is performed. This is because, when a lottery is won in a lottery in the slot machine, the symbol related to the role is displayed as the active line 2 at the position where the ON of the stop switch 42 (described later) is detected.
When it does not stop on the second line, the reel 31 is controlled to move so that the symbol related to the winning combination is actively stopped on the activated line 22, thereby increasing the winning probability of the winning combination. The stop control of the reel 31 is usually set to 19 ms or less (within 5 symbols counted from the position where the stop switch 42 is detected to be on). Therefore, if you arrange the same symbol within five intervals,
This is because the symbol can be stopped at a desired position.

When no role is won in the lottery of the role in the slot machine, that is, at the time of the loss, if the reel 31 stops at the position where the stop switch 42 is detected to be on, a certain role is won. Even in the case where the symbol 31 is moved, the reel 31 is controlled to move so that the symbol related to the winning combination is not stopped on the activated line 22.

As described above, in the symbol arrangement of the reel 31 shown in FIG. 2, even when the stop switch 42 is turned on at any position, the three types of symbols "bell", "plum" and "replay" are used. By controlling the movement of the reel 31, the symbols can be controlled to stop at desired positions on the payline 22. For example, left reel 3
Taking "bell" as an example in 1, this symbol is 3
Nos. 7, 7, 12, 17 and 20 are arranged. For example, even when the stop switch 42 is turned on at the position of the 16th "BAR" symbol, the left reel 31 is stopped at the 12th "bell" position, which is 5 symbols away from this position. Can be. Therefore, even if the stop switch 42 is turned on at any position of the rotating reel 31, the pull-in probability in the three types of symbols “bell”, “plum” and “replay” is 1
00%.

FIG. 3 shows a slot machine 10 according to this embodiment.
It is a figure showing a combination of winning symbols and their winning combinations. In the present embodiment, a special bonus includes a big bonus and a regular bonus. Also, the design corresponding to the role,
From the big bonuses “Red 7” and “Blue 7”, the regular bonus “BAR”, the small roles “Bell”, “Plum” and “Cherry” and the replay role “Replay” It is configured. With respect to the symbols other than "Cherry", a winning is achieved when these symbols on all the reels 31 are aligned on any of the activated lines 22a to 22c. Also, for the "Cherry" design,
When the "cherry" symbol on the left reel 31 stops on the pay line 22, a win is made.

Further, in the present embodiment, there are two types of combinations of shift symbols for shifting from the general game in the big bonus game to the bonus game (three “replay” symbols and three “plum” symbols are provided, respectively). Thing) is provided. Furthermore, during the bonus game, a combination of two kinds of winning symbols (three “Replay” symbols and three “Plum” symbols) are provided, and the payout number of medals at the time of winning each differs. That is, 15 medals are paid out when a winning is achieved by a combination of "plum" symbols, and 6 medals are paid out when a winning is achieved by a combination of "replay" symbols.

The description returns to FIG. In the front panel 20, in FIG.
Reference numeral 5 denotes an LED for displaying the number of medals according to the number of payouts at the time of winning. On the other hand, the stored medal number display L on the lower right side
The ED 27 is an LE for displaying the number of stored medals.
D. Furthermore, two times display LED on the upper side
28 (28a and 28b) are provided. The number-of-times display LED 28b on the left is an LED for displaying the number of bonus games during the big bonus game and the like. The number-of-times display LED 28a on the right is an LED for displaying the number of general games in the big bonus game, the number of winnings in the bonus game, and the like.

In the front part of the housing, the start lever 41 is a lever operated by the player when the rotation of the reel 31 is started. In addition, three stop switches 42 are provided independently for each reel 31,
This is a switch (button) operated by the player to stop the rotation of each reel 31.

Next, a game outline of the slot machine 10 according to the present invention will be described. First, in the base game, the player inserts medals through the medal slot 23, activates the activated line 22, and activates the start lever 41.
Turn on. Thereby, each reel 31 is started.
Then, the player presses the stop switch 42 to stop the rotation of the reel 31. Here, when the combination of the symbols of the reels 31 stopped on the activated line 22 matches the combination of the symbols of any predetermined combination shown in FIG. 3, a winning is achieved, and the payout of medals or the like is performed according to the established combination. Done. For example, when symbols such as "red 7" and "blue 7", which are big bonuses, are lined up on the activated line 22, a payout of a predetermined number is performed, and then a big bonus game different from the normal game (1 of the special game) is performed. Starts).

In the big bonus game, a general game in the big bonus game starts first, and if a combination of shift symbols for shifting to the bonus game is stopped on an active line during the general game, the game shifts to the bonus game. I do. Then, in the bonus game, a mode is set in which a specific combination (combination of “plum” symbol or “replay” symbol in FIG. 3) wins with a high probability, and the specific combination reaches a predetermined number of winnings or the bonus game. When the number of games in the game reaches the predetermined number, the bonus game ends and the process returns to the normal game in the big bonus game again. As described above, during the big bonus game, the transition from the general game to the bonus game and the transition from the bonus game to the general game are repeated, and the number of general games during the big bonus game is a predetermined number (for example, 30).
Times), or when the bonus game ends when the number of transitions from the general game to the bonus game reaches a predetermined number (for example, two times), the big bonus game is set to end.

Similarly, the regular bonus “BA
When the symbol "R" is awarded on the activated line 22, a regular bonus game (one of special games) different from the base game is started as described above. In this regular bonus game, a game corresponding to the bonus game in the above-described big bonus game is performed. In addition, in the base game, the symbols of the small role "bell" or "plum" are stopped on the activated line 22 or
Or, the symbol of “Cherry” on the left reel 31 is the valid line 2
When the player stops at 2, the small prize is won and the payout of the number of medals shown in FIG. 3 is performed. Further, when the “replay” symbols are aligned and stopped on the activated line 22, the right to play the game again while maintaining the number of medals inserted in the previous game is given.

In the present invention, when the big bonus game ends, the game is set to shift to the bonus game under certain conditions, in addition to returning to the normal game.
In the game with the privilege, the game proceeds in a state more advantageous for the player than the base game. For example, as a first mode, the stop control of the reel 31 is not controlled under a certain condition, and the reel 31 stops at the same time as the stop switch 42 is turned on. There is one that can aim for a prize. However, the player can only aim for a prize in a small role, and if the special role is won if the reel 31 is stopped without control as it is, the stop control of the reel 31 is performed. Slot machine 1
Unless a special combination is won in the lottery inside 0, the special combination is controlled so as not to win.

Then, the number of games in the uncontrolled state of the reel 31 reaches the specified number of times, or the net number of medals obtained by the player (the number of medals inserted by the player and the payout by the slot machine 10). When the difference from the number of issued medals, that is, the number of medals substantially acquired by the player) reaches the specified number, the bonus-added game is terminated and the normal game is returned. Here, during the game with the privilege, a lottery is performed for each game as to whether or not to continue the game with the privilege, and if the lottery is won, the next game also performs the game with the privilege, but if the lottery is not reached, the normal game is performed. It may be made to shift to. In addition, during the game with the privilege, the lottery of the role is performed inside the slot machine 10, and when the big bonus is won in the lottery, the control is performed so that the game with the privilege is ended.

As a second mode of the game with the privilege,
The winning probability of the special role may be higher than the winning probability in the base game. For example, it is possible to set the winning probability of the big bonus during the game with the benefit to about several times that of the base game. Further, such a game with a privilege may be performed until the next special role is won, or the game may continue until a predetermined number of games (for example, 100 times). May be returned to. Note that the bonus game in the following embodiment will be described with reference to the first mode described above, that is, a game in which the stop control of the reel 31 is not controlled under certain conditions.

Further, according to the present invention, when the game shifts to the big bonus game, the player is notified of the possibility of shifting to the special bonus game in at least one of the general game and the bonus game during the big bonus game. I do. In the present invention, as a method of notifying the possibility of the transition, the transition to the bonus game is performed by increasing the appearance rate of the specific symbol pattern during the big bonus game as compared to the transition to the base game.

As the specific symbol pattern, for example,
Another example is to set one of a combination of a plurality of symbols constituting a small combination in a general game in the big bonus game to a specific symbol pattern. That is, among the plurality of small wins shown in FIG. 3, for example, a combination of "bell" symbols is used as a specific symbol pattern. As a result, when the game is shifted to the bonus-added game, the reel 31 is stopped and controlled in the general game in the big bonus game so as to increase the winning of the small combination by the combination of the "bell" symbols. Here, when the game is shifted to the normal game, the reel 31 may be stopped and controlled so as to increase the winning of the combination of the symbols (other than the “bell” symbol) constituting the other small winning combinations. . Secondly, as in the present embodiment, a plurality of combinations of shift symbols in the general game in the big bonus game are provided, and a specific combination of shift symbols (for example, a combination of “plum” symbols) is selected from among these combinations of shift symbols. ) Is set as a specific symbol pattern. Thus, when the game is shifted to the bonus game, the probability of shifting to the bonus game is increased by the combination of the “plum” symbols, and when the game is shifted to the normal game, the combination of the “replay” symbols is changed. Increase the probability of shifting to a bonus game.

Thirdly, a plurality of combinations of winning symbols in the bonus game in the big bonus game are provided as in the present embodiment, and a specific one (for example, a combination of “plum”) is set as a specific symbol pattern. It is mentioned. Fourth, stop control of the combination of the above-described first to third symbols on the specific effective line 22 can be mentioned. For example, five effective lines 22a to 22
Among c, control is performed to increase the probability that the specific symbol pattern is aligned with the horizontal effective line 22a in the horizontal direction.

Fifth, control is performed so that a specific symbol pattern that is not a combination of symbols serving as a winning combination or the like appears. For example, using the "bell" design,
The "bell" symbol of the left reel 31 and the right reel 31 is stopped on the effective line 22a, and the "bell" symbol of the middle reel 31 is stopped on the upper and lower effective lines 22b. In order to stop the middle reel 31 in this manner, the "bell" symbols arranged in the first and third positions in FIG. 2 may be used. When the "bell" symbol is stopped in this way, the display window 2
In FIG. 1, the “bell” symbol is stopped and displayed in a substantially rhombic shape, and a specific symbol pattern can be displayed so that the player can easily understand the symbol.

In particular, in the present embodiment, it is preferable that the symbol constituting the specific symbol pattern is any one of "bell", "plum" or "replay" symbol or a combination thereof. As described above, the pull-in probability of these three symbols is 100%.
This is because, even when the stop switch 42 is turned on by the player at any of the positions, the "bell", "plum" or "replay" symbol can be drawn on the activated line 22 and a specific symbol pattern can appear. .

The appearance rate of the specific symbol pattern informs the player of the possibility of transition to the bonus game after the end of the big bonus game, but the appearance rate can be set arbitrarily. it can. For example, the appearance rate of a specific symbol pattern is set to be higher only when shifting to a game with a bonus than when shifting to a base game, and finally notified to a player at the end of a big bonus game. It may be. On the other hand, when a specific symbol pattern appears, it may be determined to shift to a game with a privilege.

Further, the appearance of the specific symbol pattern may be performed by at least one of the above-described first to fifth examples, or may be performed by combining them.
As described above, if the player is notified of the possibility of shifting to the special bonus game after the end of the big bonus game by the appearance rate of the specific symbol pattern, the player Based on the appearance rate, it is possible to predict whether or not to shift to a game with a privilege. Further, conventionally, the big bonus game tends to be monotonous, but by controlling as described above, it is possible to give a sense of tension and expectation during the big bonus game.

Next, the control operation inside the slot machine 10 will be described. FIG. 4 is a block diagram showing an outline of control of the slot machine 10. As shown in FIG. In FIG. 4, a game control means 60 including a CPU mounted on a main board or the like is shown.
Is the part that controls the progress of the entire game. A start lever 41 and a stop switch 42 are electrically connected to an input side of the game control means 60, and a motor 32 and the like connected to each reel 31 are electrically connected to an output side thereof. I have.

The game control means 60 controls the start lever 4
When the ON signal of the stop switch 42 is detected, the motor 32 is driven to rotate each reel 31, the lottery of the role is performed by the role lottery means 61. The design of the reel 31 to be stopped on the active line 22 is determined based on the lottery result by the lottery means 61 and the like, the motor 32 is controlled and driven to stop, the rotation of the reel 31 is stopped, Are stopped on the effective line 22.

The lottery means 61 performs lottery for a winning combination (special combination such as big bonus and regular bonus, small combination or replay). The role lottery means 61 includes, for example, a random number generating means (hard random number or the like) for the role lottery, a random number extracting means for extracting a random number generated by the random number generating means, and a random number value extracted by the random number extracting means. Determining means for determining whether or not a winning combination has been won and determining a winning combination based on an area to which the random number value belongs.

The random number generation means of the combination lottery means 61 generates random numbers in a predetermined area (for example, 0 to 65535 in decimal system). The random number extracting means extracts a random number generated by the random number generating means under a predetermined condition (for example, operation of the start lever 41). The lottery table is set at a predetermined ratio in advance, such as a special role (big bonus etc.) winning area, a small winning area, a replay winning area, a non-winning area, etc., in all areas taken by the random number value extracted by the random number extracting means. Provided area. The determining means calculates the random number value extracted by the random number extracting means,
By comparing with the lottery table, the area to which the random value belongs is determined, and the hand corresponding to the area to which the random value belongs is determined. For example, if the extracted random number value belongs to the big bonus winning area, it is determined that the big bonus has been won, and if it belongs to the non-winning area, it is determined that it has not been won.

The transfer game lottery means 62 is
When a big bonus, which is one of the special roles, is won in 1, a lottery is performed to determine whether the game to be shifted to after the end of the special game is a normal game or a bonus game. In the same manner as in the above, it is determined whether the game is the base game or the bonus game using the random number generating means and a predetermined lottery table. The transfer game lottery means 62
Can be performed at any time before the winning of the special combination as long as the special combination is won by the combination lottery means 61. In addition to the lottery by the role lottery means 61, the lottery by the transition game lottery means 62 can be performed. For example, in the lottery table of the role lottery means 61, the big bonus winning area is divided into two areas, one area is a big bonus winning area for shifting to a game with a privilege, and the other area is a big bonus winning area for shifting to a normal game. Just do it.

Further, the lottery by the transition game lottery means 62 may be performed after the transition to the big bonus game, before the stop control of the reel 31 by the later-described specific symbol pattern appearance control means 78. For example, when the stop control of the reel 31 by the specific symbol pattern appearance control means 78 is performed only in the bonus game in the big bonus game, even if the lottery is performed during the general game in the big bonus game which is performed first in the big bonus game. good.

The reel control means 63 controls the movement of the reel 31 as described above in accordance with the result of the lottery by the lottery means 61. That is, when any combination is won by the combination lottery means 61, the reel 3 corresponding to the winning combination is selected.
Control is performed such that one symbol stops on the effective line 22 as much as possible. In addition, when the lottery of the winning lottery means 61 deviates, the reel 31 is moved and controlled so that the combination of the symbols of the reels 31 constituting the winning combination is not aligned on the active line 22.

The winning detecting means 64 detects whether or not the combination of symbols stopped on the activated line 22 is a combination of symbols constituting a winning combination when the reel 31 is stopped. In a normal game, a combination of a special role such as a big bonus, a small role, or a replay symbol is used as an active line 22.
It is detected whether or not the combination of small symbols and the combination of shift symbols for shifting to the bonus game have stopped on the activated line 22 during the general game in the big bonus game. In the bonus game, it is detected whether or not the combination of the winning symbols has stopped on the activated line 22. For example, the stop position (angle) of the motor 32 of each reel 31 is stored so as to correspond to the reel symbol, and the stop angle of the motor 32 is detected by a sensor or the like to determine the symbol on the activated line 22. I do. The payout means 65 controls to pay out a predetermined number of medals from the hopper to the player at the time of winning.

The following big bonus game shifting means 71
The appearance number display means 80 mainly relates to control during the big bonus game. The big bonus game shifting means 71 shifts from the base game to the big bonus game when the big lottery is won by the role lottery means 61 and the winning detecting means 64 detects a winning of a combination of symbols constituting the big bonus. Things.

The number-of-general-games counting means 72 in the big bonus game counts the number of general games in the big bonus game excluding a bonus game described later. The bonus game shifting means 73 shifts to the bonus game when the winning detection means 64 detects a winning combination of shift symbols for shifting to the bonus game during the general game in the big bonus game.

The number-of-transitions counting means 74 counts the number of transitions from the general game to the bonus game in the big bonus game. The big bonus game ending means 75 is provided when the general game number counting means 72 has counted a predetermined number of games (30 times in the present embodiment) during the big bonus game, or when the number of transitions counting means 74 has reached a predetermined number (in the present embodiment). When one of the bonus games in the case of counting (2 times) is completed, the big bonus game is completed, and the base game or the bonus game is performed based on the lottery result of the transition game lottery means 62. It is to shift to.

The bonus game number counting means 76 counts the number of games in each bonus game in the big bonus game. The bonus game winning number counting means 77 counts the number of times the winning symbol combinations are aligned on the active line 22 in each bonus game in the big bonus game. As a result of the lottery by the transition game lottery means 62, the specific symbol pattern appearance control means 78 determines the specific symbol in at least one of the general game and the bonus game during the big bonus game. The reel 3 is set so that the appearance rate of the pattern is higher than when the game is shifted to the base game.
1 is controlled to stop.

Further, a specific symbol pattern appearance control means 7
8 not only controls the movement and stop of the reels 31, but also has a lottery means related to the appearance of a specific symbol pattern. As a specific method of the lottery means, the random lottery for appearance control of a specific symbol pattern and the lottery table are used in the same manner as the above-mentioned lottery means 61. For example, when a combination of specific symbols constituting a small combination in a general game in the big bonus game is set as a specific symbol pattern, the specific symbol pattern appearance control means 78
Performs a lottery of a specific symbol pattern for each of the general games. Then, when the game is shifted to the bonus game, a lottery table having a high selection probability of the specific symbol pattern is used. On the other hand, when it is decided to shift to the base game, a lottery table having a low specific symbol pattern selection probability is used in the lottery.

When the specific symbol pattern is set to a specific combination of shift symbols in the general game in the big bonus game, or when the specific symbol pattern is set to a specific combination of winning symbols in the bonus game in the big bonus game, The appearance of the specific symbol pattern is controlled as follows. For example, if the combination of the “plum” symbol and the combination of the “replay” symbol are set to the specific symbol pattern, and the game is to be shifted to the bonus-added game, the “plum” symbol is selected by lottery. When the selection probability of the symbol combination is increased to shift to the base game, the selection probability of the “replay” symbol combination is increased by lottery.

The appearance frequency counting means 79 counts the number of appearances of the specific symbol pattern in the specific symbol pattern appearance control means 78. Appearance count display means 8
0 indicates the number of appearances of the specific symbol pattern so as to be visible to the player based on the count result of the number-of-appearances counting means 79. In the present embodiment, the number of appearances is determined using the number-of-times display LED 28 or the like. indicate. The player
By seeing the number of appearances displayed by the number-of-appearances display means 80, it can be used as a guide for predicting whether or not to shift to the bonus-added game after the end of the big bonus game. It is needless to say that a dedicated display means for displaying the number of appearances of the specific symbol pattern may be provided in the slot machine 10.

The following number-of-games-with-privilege counting means 81 to ending-game-with-privilege means 84 mainly relate to control during the game with privilege. The in-game-with-privilege game frequency counting means 81 counts the number of games in the game with privilege. The number-of-payouts calculating means 82 calculates the number of coins inserted by the player and the number of medals paid out to the player during the bonus-added game, and calculates the above-mentioned net additional number from the number of medals. is there.

The in-game reel control means 83 with the privilege
The stop control of the reel 31 during the bonus-added game is performed. During the game with the privilege, the stop of the reel 31 is basically not controlled, so that the rotation of the reel 31 is stopped at the same time as the stop switch 42 is turned on by the operation of the player. Thereby, the player can stop on the pay line 22 aiming at the symbol constituting the small combination. However, if the combination of the symbols constituting the special combination stops on the activated line 22 when the rotation of the reel 31 is stopped at the same time when the stop switch 42 is turned on, the reels are set in order to avoid winning of the special combination. 31
Stop control. When it is determined that the condition for ending the game with the privilege is satisfied, for example, the number of medals obtained by the player (the net increase) exceeds the specified number, or the number of games exceeds the specified number. In this case, the game with the privilege is ended and the game is shifted to the normal game. In addition, during the game with the privilege, the lottery of the special role excluding the small role is performed by the role lottery means 61, and when the big bonus is won in this lottery, the game with the privilege is ended. Also, when the regular bonus is won, after the regular bonus game ends,
The game with the privilege is continued again.

Next, the flow of the game of the slot machine 10, particularly the flow of the big bonus game and the bonus-added game, will be described with reference to flowcharts. 5 to 7
Up to this is a flowchart illustrating the flow of the big bonus game of the present embodiment. First, in step S1, the player inserts medals through the medal insertion slot 23,
The activated line 22 is activated, the start lever 41 is turned on, and each reel 31 is started. Game control means 60
Continues to detect whether or not the start lever 41 is turned on. When the start lever 41 is turned on, the process proceeds to the next step S2, and the role lottery means 61 performs lottery selection using, for example, a hard random number. The winning combinations of the base game include a big bonus and a regular bonus, which are special combinations, and a small combination and a replay (see FIG. 3).

In the next step S3, it is determined whether or not the big bonus has been won.
In step 4, the transfer game lottery means 62 performs a lottery to determine whether the game to be transferred after the end of the big bonus game is a bonus game or a base game. On the other hand, step S3
If you did not win the big bonus in step S8
Proceed to. In the next step S5, it is determined whether or not the transition to the game with the privilege has been won. If the game has been won, the process proceeds to step S6, and the flag indicating the transition to the game with the privilege is turned on. On the other hand, when it is determined in step S5 that the game is not shifted to the bonus game, that is, when it is determined that the game is shifted to the normal game, the process proceeds to step S7, and the flag is turned off.

Next, when the player presses the stop switch 42, the rotation of the reel 31 is stopped. In step S8, whether or not all the reels 31 have stopped is continuously determined based on the output from the stop switch 42, the drive signal from the motor 32, and the like. When it is determined that all the reels 31 have stopped, the process proceeds to step S9. The winning detection means 64 determines whether or not the combination of the symbols constituting the big bonus has stopped on the activated line 22. When the combination of the symbols constituting the big bonus is aligned on the activated line 22 (when the “red 7” or “blue 7” symbols are aligned), the winning of the big bonus is made, and the process proceeds to step S10. on the other hand,
The combination of the symbols that make up the big bonus is activated line 2
If it does not stop on the second (the big bonus does not win), the process proceeds to “A” in the figure. After proceeding to "A" in the figure, the process ends without any prize processing at the time of loss, and the process ends after performing predetermined processing such as payout of medals at the time of winning a small role, At the time of winning the replay, the processing is terminated and a re-game is performed in which the number of medals inserted in the previous game is maintained.

In step S10, the general game number counting means 71 during the big bonus game initializes the general game number N during the big bonus game (N =
0), the number-of-transitions counting means 72 calculates the number of transitions C from the general game to the bonus game in the big bonus game.
Is initialized (C = 0). Then, the next step S11
The big bonus game shifting means 71 shifts the normal game to the general game in the big bonus game,
Start this general game.

First, in this general game, step S1
In step 2, it is determined whether or not the flag indicating the transition to the game with the privilege is on. When the flag is on, that is, when the game is transitioned to the privileged game, the process proceeds to step S13. When the flag is off, When shifting to the normal game, the process proceeds to step S14. In step S13 and step S14, the specific symbol pattern appearance control means 78 performs a small lottery and a shift symbol lottery in the general game in the big bonus game for each game. In the present embodiment, the combination of the "bell" symbol among the small symbol designs and the combination of the "plum" symbol among the shift symbols are set as the specific symbol pattern.

If the flag is on, step S13
In, the symbols constituting the specific symbol pattern among the winning symbols are set to be won with a high probability. That is,
The small symbol "Bell" wins with a high probability,
The "plum" symbol, which is one of the shift symbols, is set to win with a higher probability than the "replay" symbol, which is another shift symbol. On the other hand, if the flag is off,
In step S14, the winning of the small symbol "bell" is set with a low probability, and the "replay" symbol, one of the shift symbols, has a higher probability than the "plum" symbol, another shift symbol. It is set to win. Then, based on the above-mentioned lottery, when the flag is on, the specific symbol pattern appearance control means 78 controls the reel 31 to stop so that the appearance rate of the combination of the “bell” symbols increases. When shifting to the bonus game, the reel 31 is controlled to stop so that the appearance rate of the combination of the “plum” symbols increases.

In step S15, the winning detection means 64
When the reel 31 is stopped, it is determined whether or not a combination of winning symbols such as small wins is stopped on the activated line 22. If the small winning wins, the process proceeds to step S16 and the payout means 65 As a result, payout of medals according to the combination is performed. Then, in step S17, the general game number counting means 72 during the big bonus game adds 1 to the general game number N, and proceeds to step S18. In step S18, the big bonus game ending means 75 determines whether or not the general game number N has reached 30 times (whether or not the general game number counting means 72 has counted the general game number N 30 times during the big bonus game). Is determined, and when the number N of general games reaches 30 times, the condition for terminating the big bonus game is satisfied, so the flow proceeds to step S30, and the big bonus game ending means 75 ends the big bonus game. On the other hand, when it is determined in step S18 that the number N of general games has not reached 30 times, the process returns to step S11 to continue the general game in the big bonus game.

On the other hand, if it is determined in step S15 that there is no winning such as a small role, the process proceeds to step S19, and the winning detecting means 64 determines whether or not the combination of the shift symbols has stopped on the activated line 22. If the shift symbol has been won, the process proceeds to step S20. If there is no winning of the shift symbol in step S19, that is, if no winning is made, step S17
Proceed to.

At step S20, the bonus game shifting means 73 shifts to a bonus game in the big bonus game. In the bonus game, the number of games Z is counted, and the number of winnings Y in the bonus game is also counted. After the shift to the bonus game, it is first determined in step S21 whether or not the flag is on. If the flag is on, the process proceeds to step S22. If the flag is off, the process proceeds to step S23. , A lottery of the winning symbol is performed. Here, in the present embodiment, among the combinations of the “plum” symbol and the “replay” symbol, which are the winning symbols in the bonus game, the combination of the “plum” symbol is set as the specific symbol pattern.

If the flag is ON, a specific symbol pattern among the winning symbols is selected in step S22.
In other words, it is set so that the “plum” symbol, which is one of the winning symbols, wins with a higher probability than the “replay” symbol, which is another winning symbol. On the other hand, when the flag is off, in step S23, it is set so that the “replay” symbol, which is one of the winning symbols, wins with a higher probability than the “plum” symbol, which is another winning symbol. . Then, based on the above-mentioned lottery, when the flag is on, the specific symbol pattern appearance control means 78 controls the reel 31 to stop so that the appearance rate of the combination of the “plum” symbols increases.
When the flag is off, the reel 31 is controlled to stop so that the appearance rate of the combination of the “replay” symbols increases.

In the next step S 24, the winning detection means 64 determines whether or not the winning symbol combination has stopped on the activated line 22 for each game. When it is determined that there is a winning, the process proceeds to step S25, and when it is determined that there is no winning, the process proceeds to step S27. In step S25, as shown in FIG. 3, the payout means 65 pays out 15 medals to the player when the winning is a combination of "plum" symbols, and 6 medals when the winning is a "replay" symbol. Pay out medals to the player.

In the next step S26, the bonus game winning number counting means 77 adds one to the winning number Y during the bonus game. In the next step S27, the bonus game number counting means 76 adds 1 to the number of games Z in the bonus game. Then, in the next step S28, it is determined whether or not a bonus game end condition is satisfied. In the present embodiment, the bonus game is set to end when the number of winnings during the bonus game satisfies one of eight times or the number of games satisfies twelve times. If these conditions are not satisfied, the process returns to step S21 to continue the bonus game. On the other hand, in step S28, the number of winnings during the bonus game is eight,
Alternatively, when it is determined that the number of games has satisfied any one of the twelve times, the bonus game ends, and the process proceeds to step S29.

In step S29, it is determined whether or not the number of transitions C to the bonus game has reached two (whether or not the number-of-transitions counting means 74 has counted the number of transitions C twice). If it has reached twice, the process proceeds to step S30, and the big bonus game ending means 75
The big bonus game is ended, and the process proceeds to step S32. On the other hand, if it is determined in step S29 that the number of transitions C has not yet reached two, the process proceeds to step S31, where the number-of-transitions counting means 74 adds 1 to the number of transitions C, and returns to step S11. Then, the general game in the big bonus game starts again.

When the big bonus game is over, in a step S32, it is determined whether or not the flag is on.
If it is on, the process proceeds to step S33 to shift to a game with a privilege. On the other hand, when the flag is off, the process proceeds to step S34 to shift to the normal game. In step S33 and step S34, when the game is shifted to the bonus game or the base game, a sound effect for notifying the player of the game to be shifted or a lighting effect of illuminating the reel 31 with a back lamp is performed. May be.

FIG. 8 and FIG. 9 are flowcharts showing the flow of the game with the privilege of the present embodiment. First, in FIG. 8, when the game with the privilege starts, step S5
In 1, the number of games G is initialized (G = 0), and the net increase P is initialized (P = 0). Then, in the next step S52, the player enters the medal slot 2
3. Insert medals from 3 and activate the activated line 22,
The start lever 41 is turned on, and each reel 31 is started. The game control means 60 continues to detect whether or not the start lever 41 has been turned on.
Proceeding to the next step S53, the combination lottery means 61 performs lottery selection using, for example, hard random numbers. In the lottery of this role, unlike the lottery in the base game, only the big bonus and the regular bonus, which are the special roles, and the replay, and the lottery of the small role is not performed.

In the next step S54, it is determined whether or not the big bonus, which is one of the special roles, has been won. If so, the flow proceeds to step S65 in FIG. 9 to end the privileged game. This is because a big bonus, which is one of the conditions for ending the game with the privilege, has been won. If the big bonus is not won in step S54,
Proceeding to the next step S55, it is determined whether or not a regular bonus, which is one of the special roles, has been won. If so, the flow proceeds to "B" in the figure. After proceeding to “B” in the figure, the game with the bonus is temporarily stopped, and the process shifts to the regular bonus game on condition that the combination of the symbols related to the regular bonus is stopped on the activated line 22. When the regular bonus game is over, the process returns to step S52 to restart the bonus game.

If the regular bonus has not been won in step S55, the process proceeds to the next step S56, where it is determined whether or not the replay has been won. If so, the process proceeds to "C" in the figure. After proceeding to “C” in the figure, the stop control of each reel 31 is performed based on the signal when each stop switch 42 is turned on so that the combination of “Replay” symbols is aligned and stopped on the activated line 22. I do. When the replay is won, the replay game is performed while maintaining the number of medals inserted in the previous game, and the process proceeds to step S63, in which the number-of-games-with-privileges counting means 81 adds 1 to the number of games G. I do. Step S
If no replay is won in 56, the process proceeds to the next step S57.

In step S57, it is determined by the output signal from the stop switch 42 whether or not all the stop switches 42 have been turned on by the player's operation of turning on the stop switch 42. When it is determined, the process proceeds to step S58, and it is determined whether or not stop control of the reel 31 is necessary. That is, the game with a privilege in the present embodiment is:
The stop control of the reel 31 is basically uncontrolled. For example, when the reel 31 is stopped based on the output signal of the stop switch 42, the combination of the symbols constituting the special combination stops on the activated line 22. If the special combination wins (when the special combination wins), the reel 31 is controlled to stop so that the special combination does not win. After the all stop switches 42 are turned on as described above, the reel 31
, The reel 31 may be stopped when the first or second stop switch 42 is turned on so that the special combination does not win.

If it is determined in step S58 that stop control of the reel 31 is necessary, the process proceeds to step S59,
The in-game bonus reel control means 83 proceeds to step S60 after performing the above-described reel 31 stop control. On the other hand, when it is determined in step S58 that the stop control is not necessary, the process proceeds to step S60 in which the stop control of the reel 31 is not performed.

In step S60, the winning detection means 64
Determines whether the combination of the symbols constituting the small combination has stopped on the payline 22 or not. If the combination of the symbols constituting the small combination is aligned on the pay line 22, step S6
Proceeding to 1, the payout means 65 pays out a number of medals according to the combination, and proceeds to step S62. If the winning detection means 64 does not detect a winning in step S60, the process proceeds to step S62 without performing payout processing.

In step S62, the payout number calculation means 82 calculates the net increase number P at the end of the game. In the next step S63, the number-of-games-with-privileges counting means 81 adds 1 to the number of games G.

In the next step S64, the privileged game ending means 84 determines whether or not the condition for ending the privileged game is satisfied. That is, the game with ending means 8
4 is whether or not the net increase number P reaches a specified number (for example, 214), or the number of games G is a specified number (for example, 150).
It is determined whether or not the number of times has been reached, and if at least one is satisfied, the process proceeds to step S65, and the game with the privilege is ended. On the other hand, if it is determined in step S64 that the condition for ending the game with the privilege has not been satisfied, the process returns to step S52 to continue the game with the privilege.

As described above, one embodiment of the present invention has been described. However, the present invention is not limited to the above-described embodiment, and various modifications can be made. For example, in the present embodiment, two shift symbols, “plum” and “replay”, are provided as shift symbols for shifting from the general game in the big bonus game to the bonus game. It is good. Then, when a combination of “plum” symbols is added to the small role in the general game during the big bonus game, and the game is shifted to the special bonus pattern, the “Bell” symbol (first winning symbol) which is a specific symbol pattern is used. When the appearance rate of the combination is increased to shift to the base game, the appearance rate of the combination of the “plum” symbol (second winning symbol) can be increased.

[0085]

According to the first aspect of the present invention, it is possible to notify the possibility of the transition to the game with the privilege in association with the game content during the special game, so that the player feels nervousness and expectation during the special game. Can give a feeling. According to the invention of claim 2, it is possible to notify the possibility of the transition to the game with the privilege based on the winning frequency of the combination of the specific winning symbols. According to the third aspect of the present invention, it is possible to notify the possibility of shifting to the bonus-added game by the combination of the winning frequency by the combination of the first winning symbols and the winning frequency by the combination of the second winning symbols.

Further, according to the fourth aspect of the present invention, it is possible to notify the possibility of shifting to the bonus-added game by determining on which activated line a particular symbol pattern appears in a large number. According to the invention of claim 5, in the special game having the general game and the bonus game, the notification of the possibility of shifting to the bonus game can be more widely expressed. According to the invention of claim 6, it is possible to notify the possibility of shifting to the bonus-added game depending on which combination of shift symbols shifts to the bonus game.

Further, according to the seventh aspect of the present invention, when notifying the possibility of transition to the game with the privilege based on the number of appearances of the specific symbol pattern, the number of times that the player has been displayed on the appearance number display means is reduced. By looking, the possibility of migration can be easily predicted.
