On the Ball is a puzzle game originally released in the Arcade by Taito. The player has to maneuver a marble around a maze by shifting the maze itself rather than the marble. By moving the maze left and right, the marble rolls down the sides towards the bottom of the screen. The goal is to reach the end of the maze before the timer runs out.

The player takes control of the static maze and rotates it around a free-falling ball. The goal is the guide the ball to the finish marker within a set amount of time. The time limit is designated by a countdown timer. Within the maze are obstacles such as: breakable walls, incorrect paths and time-penalty objects.
Some versions of the game include varying difficulty modes for the player to select before the start of a level or series of levels. The difficulty modes vary the countdown timer and sometimes the time-penalty incurred by objects.
