Abstract

According to a gaming machine of the present invention, a specific number of free games are generated when three or more trigger symbols have been stop-displayed in a normal game. Further, when one or two trigger symbols have been stop-displayed in a free game, numeric values in number equivalent to the number of stop-displayed trigger symbols are selected, and then the number of times obtained by summing up the selected numeric values is added to the number of free games.

Claims (13)

1. A gaming machine having at least a state of a first game and a state of a second game to which the state of the first game shifts and awards a predetermined benefit when at least a predetermined number of trigger symbols are rearranged as a result of variably displaying and rearranging a plurality of symbols in the state of the first game or in the state of the second game,

the gaming machine comprising a controller programmed so as to execute a gaming process in which:

the first game state and the second game state are different from each other in the predetermined number of the rearranged trigger symbols required to award the predetermined benefit and

the predetermined benefit is a free game as the second game which does not require a new bet; wherein

the controller is programmed so as to also execute processes of:

in the first game, awarding a specific number of free games if the at least the predetermined number of trigger symbols required in the state of the first game are rearranged as a result of variably displaying and rearranging the plurality of symbols;

in the free game, awarding the specific number of free games if the at least the predetermined number of trigger symbols required in the free game as the second game are rearranged as a result of variably displaying and rearranging the plurality of symbols, wherein in the free game, the number of the trigger symbols required for awarding the specific number of free games is smaller than the number of the trigger symbols required for awarding the specific number of free games in the first game, and, wherein, in the free game, the number of free games awarded, when the at least the predetermined number of the trigger symbols are rearranged, is smaller than the number of free games awarded when the at least the predetermined number of the trigger symbols are rearranged in the first game.

2. A method of controlling a gaming machine, which is executed by a processor of the gaming machine, wherein,

when executing a process which has at least a state of a first game and a state of a second game to which the state of the first game shifts, in which, when at least a predetermined number of trigger symbols are rearranged as a result of variably displaying and rearranging a plurality of symbols in the state of the first game or in the state of the second game, a predetermined benefit is awarded,

the processor differentiates the state of the first game from the state of the second game in the number of the predetermined rearranged trigger symbols required for awarding the predeter-mined benefit, the predetermined benefit being a free game as the second game which does not require a new bet; and wherein

the processor is programmed so as to also execute processes of:

in the first game, awarding a specific number of free games if the at least the predetermined number of trigger symbols required in the state of the first game are rearranged as a result of variably displaying and rearranging the plurality of symbols;

in the free game, awarding the specific number of free games if the at least the predetermined number of trigger symbols required in the free game as the second game are rearranged as a result of variably displaying and rearranging the plurality of symbols, wherein in the free game, the number of the trigger symbols required for awarding the specific number of free games is smaller than the number of the trigger symbols required for awarding the specific number of free games in the first game, and, wherein, in the free game, the number of free games awarded, when the at least the predetermined number of the trigger symbols are rearranged, is smaller than the number of free games awarded when the at least the predetermined number of the trigger symbols are rearranged in the first game.
