A video game apparatus has a display device for displaying visual images showing the progress of the game. An operating member is manipulated by the player in accordance with instructions displayed on a video screen within a period of time and preferably also in a preset direction, which must fall within that preset time and be in that preset direction if the player is to avoid loss of the game. The permissible time and preferably also the preset direction are indicated to the player by a visible mark on the video screen, such as an arrow which first appears only at the beginning of the period of time when the player can successfully manipulate the operating member, and which points in the direction in which the player must operate the operating member if the game is to continue. Alternatively, the indication is audible. If the player succeeds, then success images appear on the screen; but if the player fails, then game loss images appear on the screen.
