Game system with mechanism for determining whether to trigger three-dimensional re-spinning

Abstract

The present invention is to determine whether a game result of a slot machine satisfies a specified condition by using a control unit, the specified condition is defined as any one of the plurality of game symbols in the game result replaced so that the reward condition is satisfied, and one of the game symbols replaced to be located at a replacement position; when the control unit determines that the game result satisfies the specified condition, the control unit activates a three-dimensional re-spinning component to generate a replacement game symbol. The replacement game symbol is used to replace the game symbol at the replacement position and update the game result, thereby the control unit re-determines whether the updated game result meets the reward condition, and after the reward condition is met, performs a reward program by using a reward unit.
