PROBLEM TO BE SOLVED: To lighten concentration to a specific scene of expectation toward extension of a period controlled to an advantageous state.SOLUTION: A game machine is configured to identify an addition rate between respective objects to be added in additional lottery processing by a combination pattern determined with start of an ART mode as an opportunity. Thus, every time when the ART mode is started, a relationship of the addition rate between the respective objects to be added can be changed. As a result, a sense of expectation toward addition can differ according to a situation in the additional lottery processing to the respective objects to be added, thus relaxing concentration to a specific scene of expectation toward extension of a period controlled to an advantageous state of a probability variation mode and the ART mode. |
