BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is provided in such a manner that a plurality of drums having various kinds of identification information drawn on an outer peripheral surface are rotated based on establishment of a predetermined starting condition, and are provided in association with each drum. A game in which the drum is stopped in accordance with the operation of the stop switch is executed, and when the stop mode when all the drums are stopped is a winning pattern in which specific identification information is aligned on a valid line, the above-mentioned condition is more advantageous than usual. The present invention relates to a slot machine that shifts to a special game state in which a game can be played.

[0002]

2. Description of the Related Art Conventionally, a slot machine has three drums on which a plurality of identification information (generally, a symbol such as 7, bell, cherry, etc.) is drawn on an outer peripheral surface. The drums are rotated simultaneously by operating the starting lever after inserting one to three medals. Each of the drums is provided with a corresponding stop switch, and pressing these switches stops the rotating drum. Then, when all the drums are stopped, when a predetermined symbol is arranged on an effective line, a winning is won, and a predetermined number of medals according to the symbol at that time are paid out to the player. I have.

[0003] When a winning pattern in which a predetermined specific symbol is aligned on an activated line appears, a jackpot is won, and a special game state (generally, a large bonus game or the like) in which a game can be played under more advantageous conditions than usual. (A special game state called a small bonus game), and a large number of medals are provided to the player to give profit.

Normally, a slot machine has a winning state in which a winning pattern can appear on an activated line and a gaming state in which a winning pattern does not appear on an activated line or has an extremely low appearance probability. It is set so that a winning state can appear according to a predetermined probability.

[0005] Further, even in the winning state, the identification information on each rotating drum is observed, and the stop button is pressed to aim at the identification information so that the target identification information stops on the effective line. If no so-called eye pressing is performed, the winning patterns are not easily aligned.

[0006]

In the conventional slot machine, in order to stop each drum, it is necessary to press a stop switch for each drum.
Even if the winning state was entered, the winning patterns would not be complete unless the eyes of all the drums were successful. For this reason, there is a problem that a player who is not good at sighting consumes a large number of medals until the winning patterns are aligned, and even if the player enters the winning state, he cannot fully enjoy the benefits. there were.

When the small bonus symbol has stopped (step S703; Y), a predetermined number of medals are paid out or added to the credit (step S708), and the flag establishment lamp 146 is turned off (step S709).

If the game does not stop at the small bonus symbol (step S703; N), it is determined whether the game has stopped at the missing symbol (step S704). If the symbol has stopped (step S704; Y), the game start processing is performed. Execute (step S707), and return to the bonus drum rotation processing (step S702). On the other hand, when the small combination (combination with a small number of payouts other than the large bonus and the small bonus) is realized (step S704; N, step S705), a predetermined number of medals are paid out or added to the credit (step S706). , A game start process is executed (step S
707), bonus drum rotation processing (step S70)
Return to 2).

FIG. 8 shows the flow of the drum rotation process. When the drum starts rotating (step S801),
Immediately, the drums 131 to 133 perform a control of rotating and aligning the bonus symbols (the large bonus symbol when the random number is a large bonus random number, and the small bonus symbol when the random number is a small bonus random number) (step S802).

That is, in the case of the large bonus random number, the relative positions of the respective drums are adjusted during rotation so that "777" is aligned in a horizontal line, and three drums 131 to 133 are aligned in a horizontal line with "777". While maintaining the same relative positional relationship, they rotate at the same speed. In the example shown in FIGS. 9 to 11, first, rotation of each drum starts from the state of FIG. 9A,
The rotation is performed with the relative position of the drum being arbitrary as shown in FIG. 9B, and immediately thereafter, as shown in FIG.
Are adjusted in such a manner that are aligned in a horizontal line. Thereafter, the rotation is continued while maintaining the state (FIG. 1
0b, FIG. 11a).

In the case of the small bonus random number, the relative positions of the respective drums are adjusted during rotation so that “BAR, BAR, BAR” are aligned in a horizontal line.
1 to 133 rotate at the same speed as each other while maintaining the relative positional relationship of “BAR, BAR, BAR” aligned in a horizontal line. In the example shown in FIGS. 12 to 14, first, FIG.
The rotation of each drum starts from the state shown in FIG. 12B, the rotation is performed with the relative position of the drum being arbitrary as shown in FIG. 12B, and immediately thereafter, “BAR, BAR, BA” as shown in FIG.
R "is adjusted so that their relative positions are aligned in a horizontal line,
Thereafter, rotation is continued while maintaining that state (FIGS. 13b and 14a).

It is determined whether a predetermined time has elapsed from the start of rotation (step S803). If the predetermined time has not elapsed (step S803; N), it is determined whether the stop switch has been pressed (step S803). S804).
When one of the left, middle, and right stop switches is pressed (step S803; Y), all the drums are stopped at the same time (step S805).

If the stop switch has not been pressed (step S803; N), when a predetermined time has elapsed from the start of rotation (step S803; Y), all the rotating drums are forcibly stopped (step S806). The rotation processing ends. The rotation of each drum is controlled in a non-controllable mode in which it can be pushed. Also, the forced stop
It stops at random and large bonus symbols or small bonus symbols are not always aligned on the activated line. Note that FIG.
FIG. 14B shows a state where the large bonus symbol “777” is aligned on the activated line by eye-catching, and FIG. 14B shows a state where the small bonus symbol “BAR, BAR, BAR” is aligned on the activated line by eye-catching. Each state is shown.

FIG. 15 shows the flow of the drum rotation process. The drum starts rotating (step S1501),
It is determined whether a predetermined time has elapsed since the start of rotation (step S1502). If the predetermined time has not elapsed (step S1502; N), it is determined whether the stop switch has been pressed (step S1503). If the stop switch has been pressed (step S150
3; Y), it is determined whether or not the corresponding drum is rotating (step S1504). If the corresponding drum is rotating (step S1504; Y), the drum is stopped (step S1505). It is determined whether or not all the drums (the right drum 133, the middle drum 132, and the left drum 131) have stopped rotating (step S1506). If all the drums have stopped (step S1506; Y),
The drum rotation processing ends.

If the stop switch is not pressed (step S1503; N) or if the corresponding drum is stopped when the stop switch is pressed (step S1504; N), it is determined whether a predetermined time has elapsed from the start of rotation. The process returns to the determination.

When a predetermined time has elapsed since the start of rotation (step S1502; Y), all the rotating drums are forcibly stopped (step S1507), and the drum rotation process ends.

FIG. 16 shows the flow of the off symbol processing. First, the drum rotation process described above is executed (step S1601), and it is determined whether or not the misaligned symbols are stopped when all the drums are stopped (step S1602). If the lost symbol has stopped (step S1602; Y), the lost symbol processing ends. If the missing symbol has not stopped (step S160)
2; N), a small win is established (step S1603), a predetermined number of medals are paid out or added to the credit (step S1604), and the lost symbol processing ends.

FIG. 17 and FIG. 18 show the flow of the large bonus game process. First, a game start process is executed (step S1701), then a drum rotation process is executed (step S1702), and a specific symbol (a symbol which is shifted from a plural betting game to a single betting game) is generally used as a replay symbol. In the case where the so-called game is stopped (Step S1703; Y), a predetermined number of medals are paid out or added to the credit (Step S1709), and the process proceeds to A, which is a single bonus betting game process. In the single betting game process, the stop position of the drum is controlled so that the small winning combination is continuously performed a predetermined number of times (for example, eight times).

In the case of stopping at a lost symbol (step S
1703; N, step S1704; Y), the number of plural betting games is accumulated (step S1707), and it is determined whether or not the accumulated number of plural betting games has reached a predetermined upper limit (step S1708). If the accumulated number of betting games reaches the upper limit (step S1708; Y), the process proceeds to A. If the upper limit is not reached (step S1708; N), the process returns to the start of the game process (step S1708). S1701). In other words, the single betting game process in which the small winning combination is formed a predetermined number of times in succession is started when a specific symbol appears or when a certain number of games are consumed without the specific symbol appearing. .

In the case of shifting to A, a single betting game start process is executed (step S1710), a loss symbol process is executed (step S1711), and the number of single betting games is integrated (step S1712). In this outlier design process, small wins appear with an extremely high probability. If the integrated number of single betting games has not reached the predetermined upper limit number (step S1713; N),
Returning to the one-sheet game starting process (step S1710), if the upper limit has been reached (step S171)
3; Y), accumulate the number of game sets (step S1)
714).

It is determined whether or not the number of game sets has reached a predetermined upper limit (usually three) (step S1).
715) If the number of game sets has not reached the upper limit number (step S1715; N), the process proceeds to B, and if the upper limit number has been reached (step S1715; Y),
Initialize the number of betting games, the number of betting games, and the number of game sets (steps S1716, S1717,
S1718), the large bonus game process ends.

FIG. 19 shows a small bonus game process. First, a single betting game start process is executed (step S).
1901) Then, a lost symbol process is executed (step S).
1902) The number of single betting games is counted (step S1903). In this lost symbol processing, a small role is played with an extremely high probability and medals are paid out. It is determined whether or not the integrated number of single betting games has reached a predetermined number (step S1904). If the number has not reached the upper limit (step S1904; N), the process returns to the single betting game start processing, and the upper limit If the number has reached (step S1904; Y), the small bonus process ends.

FIG. 20 shows the flow of the single bet game start process. In this process, one medal is inserted or one medal is inserted.
The process is performed until a credit is inserted (step S2001; Y, step S2002; Y) and the start lever 114 is operated (step S2003).

In the embodiment described above, the rotation of the actual drum is controlled, but the drum may be simulated on the screen of the liquid crystal display. Further, in the embodiment, the flag establishment lamp 146 is turned on regardless of whether a large bonus random number is output or a small bonus random number is output. A separate flag establishment lamp is provided to the player so that the player can be notified of whether the large bonus symbol has been aligned by eye pressing or the small bonus symbol has been aligned by eye pressing. You may.

According to the slot machine of the present invention, when a large bonus random number or the like is output and it becomes possible to push the drums, the relative positions of the drums are adjusted so that the winning patterns can be aligned. By rotating, all the drums are stopped at the same time while maintaining the relative position by operating one of the stop switches, so it is possible to align the winning pattern with only one press. The burden on the person can be reduced.

Since all the drums rotate together with the relative positions set so that the winning pattern can appear, the identification information constituting the winning pattern can be easily distinguished during the rotation, and the pressing can be made easier. It becomes even easier. As a result, a large number of medals are not consumed until the bonus game is performed, and the benefits of the bonus game can be sufficiently enjoyed.

Further, since the player is notified that the winning state has been entered, it is possible to know when to perform the pushing, so that even a novice can make full use of the chance of pushing.
