Patent ID: 8622827

Claim:
A game system comprising: a display device that displays and outputs a game screen; an input device including at least one operating unit; a sequence data storage device that stores sequence data in which a reference timing during a game is described; a game region presenting device that causes a game region in which a plurality of reference portions are set apart from each other to be displayed on the game screen of the display device; and a mark display control device that displays a first operation indication mark for indicating an operation on the operating unit while moving the operation indication mark in the game region such that the first operation indication mark arrives at one of the reference portions at a first reference timing designated by the sequence data, wherein the sequence data further includes display start information setting a display start timing of a second operation indication mark corresponding to a next reference timing when a time interval between the first reference timing and the next reference timing is less than a predetermined value, and the mark display control device starts to display the first operation indication mark and the second operation indication mark, the first operation indication mark being separate from the second operation indication mark corresponding to the first reference timing at the display start timing based on the sequence data corresponding to the next reference timing.
