Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slot machine, and more particularly to a slot machine which can enhance the randomness of lottery in determining a stop symbol at the time of replay and which does not disrupt the rhythm of the game.

[0002]

2. Description of the Related Art In a conventional slot machine, when a stop symbol of a variable display device is a combination of predetermined symbols, the same condition as the game is given, that is, the same number of medals as the number of medals provided for the game are given. I was playing the game again. In this slot machine, when the stop design of the variable display device becomes a predetermined re-play design, the player automatically inserts the same number of medals as the number of medals used in the game without inserting medals. To do it. After the medal is inserted, the player operates the start switch,
The random number value used for determining the stop design of the variable display device is specified while starting the change display of the design of the variable display device. The random number is updated at predetermined intervals, for example, every 1.87 msec.

On the other hand, if the replay conditions are not met,
It will be in the state of accepting the insertion of medals as usual.

[0004]

However, the time from the player automatically operating the start switch after the medals to be replayed are automatically inserted and the conditions for replaying are satisfied must be substantially constant. Therefore, the number of times of updating the random number used for determining the stop symbol of the variable display device is almost the same every time. That is, when the replay game is performed, the number of times of updating the random number for determining the stop symbol of the variable display device has a certain law.

Therefore, since the random number specified by the operation of the start switch has a certain law, it impairs the randomness of the lottery in the determination of the stop symbol at the time of the re-play, and the replay for the skilled player is repeated. There was a problem that the stop design of the variable display device during the game could be predicted, and the interest of the game was lacking. In addition, at the time of replay, there is a problem that the player breaks the rhythm of the game because the credit insertion switch is not operated unlike the normal game.

Therefore, the slot machine according to the present invention is made in order to solve the problems of the above-mentioned conventional technique, and its purpose is to draw a lottery in determining a stop symbol at the time of replay. Another object of the present invention is to provide a slot machine that enhances the randomness of the game and does not disrupt the rhythm of the game during replay.

[0007]

The present invention is to achieve the above-mentioned object, and the contents thereof will be described below with reference to the embodiments shown in the drawings. The slot machine according to claim 1, wherein when the stop design of the variable display device (20) is a combination of predetermined replay designs, replay determination means (91) for starting replay, and the replay. Game determination means (91)
On the basis of the re-game determination signal from, the re-play medal insertion means (92) for inserting a medal for a re-play is provided on condition that the credit insertion switch (54) is operated.

[0008]

[Operation] Therefore, according to the slot machine of claim 1, the player wins a predetermined number of medals by the slot machine (1
When the start switch (53) is operated by putting it in (0), the symbols displayed on the variable display device (20) are sequentially changed and displayed at high speed. Then, when the player operates the stop switches (50 to 52), the symbols which have been sequentially changed and displayed on the variable display device (20) at high speed are stopped.

Here, when the stop design of the variable display device (20) is a predetermined re-play design, the re-play determination means (91) outputs a re-play determination signal. When the player operates the credit insertion switch (54) while the replay determination signal is output, the replay medal insertion means (92)
The same condition as that of the game, that is, the same number of medals as the number of medals provided for the game are inserted.

[0010] Therefore, before the player operates the start switch (53) for starting the re-play after it is determined to be the re-play, the player inserts a credit in order to start the insertion of the medal for the re-play. Since it is necessary to operate the switch (54), the start switch (5
There is some variation in the time until operation 3). Therefore, the number of times of updating the random number used to determine the stop symbol of the variable display device (20) in the replay can be varied, and no rule can be found in the specified random number value.

Further, even in the replay, it is necessary to operate the credit insertion switch (54) as in a normal game, so that the player does not lose the timing of the game.
