Description

  The present invention relates to a slot machine, and more particularly, when a transition symbol combination is displayed in a symbol display window, based on the number of sliding symbols of a rotating reel that has stopped rotating, any one of a plurality of special games. It relates to the slot machine to be migrated.

Conventionally, a gaming machine that uses a medal as a game medium corresponds to three rotating reels each having a plurality of symbols on the peripheral surface, and a start switch for starting the rotation of each rotating reel. A slot machine having a stop switch for stopping the rotation of a rotating reel is known.
In such a slot machine, the game can be started when a medal is bet. Then, triggered by the operation of the start switch, the three rotating reels start to rotate, and a lottery of which of a plurality of winning combinations is won or lost is performed. When the winning combination is won in the lottery, when the stop switch is operated, stop control of each rotating reel is performed so that the combination of symbols related to the winning combination can be aligned on the effective line. Furthermore, when the rotation of all the rotating reels is stopped and the combination of symbols related to the winning combination is aligned with the active line, the winning combination is won and a predetermined profit is given to the player. For example, when a winning combination related to “replay” is won, it is possible to play one game again without betting a new medal.

  In addition, the slot machine includes a “normal game” that is a normal game, a “special game (for example, a big bonus or a regular bonus)” that can earn more medals than a normal game, a normal game, and a special game. There are different games such as “special games”. For example, the slot machine described in Patent Document 1 is provided with a “replay time (RT) mode” as a special game, in which the probability of winning a winning combination related to “replay” is significantly different from that of a normal game and a special game. . When the combination of special replay symbols is aligned on the effective line during the normal mode, the replay time is entered.

JP 2009-56139 A

It means the winning flag that is cleared before being played. In the present embodiment, the other winning flags excluding the “red seven winning flag”, the “white seven winning flag”, and the “BAR winning flag” are small role winning flags.

(Rotation control means 140)
The rotation control means 140 is for starting rotation of each rotary reel 23 in response to the operation of the start switch 53 and rotating each rotary reel 23 at a constant rotational speed.
Specifically, when the bet number stored in the bet number storage unit 180 is “3”, the rotation control unit 140 starts the rotation drive of each stepping motor 26 when the start switch 53 is operated. Then, the rotation of each rotary reel 23 is started. Further, the rotational drive of each stepping motor 26 is controlled so that the rotation of each rotary reel 23 is accelerated until it reaches a constant rotational speed. Then, when the rotation of each rotary reel 23 is accelerated to a constant rotational speed, the rotational driving of each stepping motor 26 is controlled so that each rotary reel 23 rotates at a constant rotational speed. .

(Rotation position determination means 150)
The rotational position determination means 150 is for specifying the rotational position of each rotary reel 23.
Specifically, index detection by each index sensor 27 is started when each rotation reel 23 accelerates to a constant rotation speed and becomes steady rotation. Then, when the index sensor 27 detects the index, the number of pulses of the stepping motor 26 is counted, and the rotational position of the corresponding rotating reel 23 is specified based on the number of pulses. The counted number of pulses is reset every time an index is detected, and the number of pulses is newly counted.

In addition, 21 symbols assigned to each rotary reel 23 are assigned symbol numbers based on the rotational position when the index sensor 27 detects the index. Specifically, symbol numbers “00” to “20” are sequentially assigned from symbols on the first effective line 37A when the index sensor 27 detects the index. In addition, a symbol type corresponding to each symbol number is stored for each rotary reel 23. Based on the rotational position of the rotating reel 23, that is, the number of pulses, the symbol number of the symbol on the first effective line 37A is specified, and the symbol type is specified based on the symbol number.
(Stop control means 160)
The stop control means 160 is for performing stop control of the rotary reel 23 based on the rotation position of the corresponding rotary reel 23 and the lottery result of the winning lottery means 130 when the stop switch 54 is operated.

  Here, the number of stop reference positions that pass through the symbol display window 31 from when the stop switch 54 is operated until the corresponding rotating reel 23 stops at one of the stop reference positions is the “slip frame number”. That's it. For example, the number of sliding symbols “0” means that the rotary reel 23 corresponding to the operated stop switch 54 is stopped at the stop reference position displayed on the symbol display window 31 first from the operation. In addition, the number of sliding symbols “1” is determined such that the rotating reel 23 corresponding to the operated stop switch 54 passes the stop reference position displayed on the symbol display window 31 first from the operation and is secondly symbolized. It means stopping at the stop reference position displayed on the display window 31. In the present embodiment, the stop control means 160 stops the rotary reel 23 at the stop reference position within the range of the number of sliding symbols “0” to “4” based on the lottery result of the winning lottery means 130. Yes.

Specifically, in the ROM of the game control device 100, based on the rotational position of the rotating reel 23 when the stop switch 54 is operated, the number of sliding symbols until the corresponding rotating reel 23 stops at the stop reference position is rotated. A stop table defined for each reel 23 is stored.
In the present embodiment, a stop table corresponding to each winning flag (for example, “red seven stop table” corresponding to “red seven winning”) is stored in the ROM of the game control device 100. In the stop table corresponding to the winning flag, the number of sliding symbols of each rotating reel 23 is defined so that the winning combination related to the winning flag can win and other winning combinations do not win. In addition, the number of sliding symbols on each rotating reel 23 so that the combination of symbols of the winning combination and “first type symbol combination”, “second type symbol combination” or “composite symbol combination” are not aligned on the effective line 37 at the same time. Is stipulated.

For example, the “Watermelon Stop Table” corresponding to “Watermelon Winning” is a combination of symbols of the winning combination other than “Watermelon Winning” so that three “Watermelon” symbols can be aligned on any active line 37 Are not aligned with the effective line 37, the number of sliding frames of each rotary reel 23 is defined.
For example, the “cherry stop table” corresponding to “cherry winning” is such that the symbol of “cherry” on the left rotating reel 23L can be displayed on the active line 37 and the symbol of the winning combination other than “cherry winning” is displayed. The number of sliding frames of each rotary reel 23 is defined so that the combinations are not aligned with the effective line 37.

  In addition, “Watermelon Stop Table” and “Cherry Stop Table” do not match any winning combination in the effective line 37 when each rotating reel 23 stops rotating. The number of sliding symbols of each rotary reel 32 is defined so that the “second type symbol combination” or “composite symbol combination” may be aligned with any of the effective lines 37. The “watermelon stop table” and “cherry stop table” indicate the number of sliding symbols of each rotating reel 23 in one game for “first type symbol combination”, “second type symbol combination” and “composite symbol combination”. In any case where the total is “0” to “12”, the number of sliding symbols of each rotary reel 23 is defined so that the effective line 37 may be aligned.

  In addition, the ROM of the game control device 100 stores a stop table used when any one of the bonus winning flags and any one of the small bonus winning flags are simultaneously provided in a predetermined area of the RAM. For example, there is a “bell / red 7 stop table” used when the “red seven winning flag” and the “bell winning flag” are simultaneously provided. These tables indicate that each rotary reel 23 has a sliding piece so that the winning combination related to the bonus winning flag can preferentially win over the winning combination related to the small role winning flag, and so that no other winning combination can win. Number is specified. In addition, the number of sliding symbols on each rotating reel 23 so that the combination of symbols of the winning combination and “first type symbol combination”, “second type symbol combination” or “composite symbol combination” are not aligned on the effective line 37 at the same time. Is stipulated.

(Other embodiments)
The present invention is not limited to the above-described embodiments, but includes modifications and improvements within a scope in which the object of the present invention can be achieved.
For example, the probability of winning the “replay winning combination” is set so that one of the first special game and the second special game is higher than that in the normal game, and the other is lower than in the normal game. It may be set, or may be set so that both during the first special game and the second special game are lower than in the normal game. In addition, for example, in one of the first special game and the second special game, information on the lottery result of the winning lottery means 130 is notified, but on the other side, this information may not be notified.

Further, for example, the stop control means 160 displays “first type symbol combination (flower / flower / ANY)” on one effective line 37 and “second type symbol combination (ANY · (Flower / flower) "may be displayed. When the display combination determining means 220 determines that “flower / flower / ANY” is displayed on one effective line 37 and “ANY / flower / flower” is displayed on a different effective line 37 at the same time. In addition, based on the number of sliding symbols stored in the number of sliding symbols storage means 210, it may be shifted to either the first special game or the second special game.
For example, the stop control means 160 may display “flowers / flowers / flowers” on the active line 37, but “flowers / flowers / any pattern (excluding flowers)” and “any pattern (flowers) Except for “Excluded” / Flower / Flower ”. When the display combination determination unit 220 determines that “flower / flower / flower” is displayed on the effective line 37, the first special is based on the number of sliding frames stored in the sliding frame number storage unit 210. You may make it transfer to either a game or a 2nd special game.

  Also, the corresponding special game lottery means 230 adds the first special game or the second special game to each of the total number of sliding symbols (total number of sliding symbols) of each rotating reel 23 in one game, that is, “0” to “12”. Any one of the first special game and the second special game is associated with the number of sliding symbols of one rotating reel 23 in one game, that is, “0” to “4”, respectively. May be associated. Then, the transition special game determination means 240 determines whether the first special game or the second game is based on the number of sliding symbols stored in the number of sliding symbols storage means 210 for the predetermined rotating reel 23 and the lottery result of the corresponding special game lottery means 230. You may make it determine in which special game it transfers.
