Gaming machine capable of realistically informing of a payout rate

Abstract

The present invention provides a gaming machine that is capable of realistically informing a player of a possibility that a payout rate becomes high, by means of an effective rendering. The gaming machine is capable of increasing a probability of migration to a bonus game and then increasing an opportunity of increasing a prize to a player by performing re-scroll while leaving a bonus symbol. In addition, the gaming machine is capable of increasing a probability of migration to a bonus game by means of an effective rendering called re-scroll to be thereby able to realistically inform a player of a possibility that a payout rate becomes high.

1 . A gaming machine comprising:
 an input device for starting a basic game;   a plurality of reels on which a plurality of symbol groups are respectively drawn;   a display configured to display an image;   an operating portion that is capable of being operated by a player, for specifying a change of a payout rate; and   a controller configured to execute processing operations of:   (a) based on an input to the input device, randomly determining symbols to be displayed for a player when scroll of a plurality of symbol arrays stops and then starting a basic game;   (b) scrolling a respective one of a plurality of symbol arrays that are displayed on the display;   (c) based on a result of the random determination, sequentially stopping a respective one of a plurality of symbol arrays that are scrolled;   (d) in accordance with an operation of the operating portion, leaving a bonus symbol for migrating to a bonus game from among the respective symbols of the stopped symbol arrays and then re-scrolling symbols;   (e) determining whether or not to migrate to the bonus game, based on a bonus symbol displayed after the re-scroll is stopped and the left bonus symbol; and   (f) executing the bonus game, based on a result of the determination.   
     
     
         2 . A gaming machine comprising:
 an input device for starting a basic game;   a plurality of reels on which a plurality of symbol groups are respectively drawn;   a display configured to display an image;   an operating portion that is capable of being operated by a player, for specifying a change of a payout rate; and   a controller configured to execute processing operations of:   (a) based on an input to the input device, randomly determining symbols to be displayed for a player when scroll of a plurality of symbol arrays stops and then starting a basic game;   (b) scrolling a respective one of a plurality of symbol arrays that are displayed on the display;   (c) based on a result of the random determination, sequentially stopping a respective one of a plurality of symbol arrays that are scrolled;   (d) in accordance with an operation of the operating portion, leaving a bonus symbol for migrating to a bonus game from among the respective symbols of the stopped symbol arrays and then randomly determining whether or not to re-scroll symbols;   (e) re-scrolling symbols, based on the determined result;   (f) determining whether or not to migrate to the bonus game, based on a bonus symbol displayed after the re-scroll is stopped and the left bonus symbol; and   (g) executing the bonus game, based on a result of the determination.   
     
     
         3 . A gaming machine that is capable of repeatedly executing a unit game, the gaming machine comprising:
 an input device for starting a basic game;   a plurality of reels on which a plurality of symbol groups are respectively drawn;   a display configured to display an image;   an operating portion that is capable of being operated by a player, for specifying a change of a payout rate; and   a controller configured to execute processing operations of:   (a) based on an input to the input device, randomly determining symbols to be displayed for a player when scroll of a plurality of symbol arrays stops and then starting a basic game;   (b) scrolling a respective one of a plurality of symbol arrays that are displayed on the display;   (c) based on a result of the random determination, sequentially stopping a respective one of a plurality of symbol arrays that are scrolled;   (d) in accordance with an operation of the operating portion, reducing a time interval from start to end of a unit game, and leaving a bonus symbol for migrating to a bonus game from among the respective symbols of the stopped symbol arrays and then re-scrolling symbols;   (e) determining whether or not to migrate to the bonus game, based on a bonus symbol displayed after the re-scroll is stopped and the left bonus symbol; and   (f) executing the bonus game, based on a result of the determination.
