Roll a ball around a walled field of green points, yellow blocks and blue fences, and score as much as you can in 90 seconds. Green scores 10, yellow costs 50 and blue costs 20, and everything the ball rolls over is used up. The trouble is the joystick. Touch a blue fence and the controls are scrambled: each of the four stick directions now moves the ball in a direction drawn at random. Every 15 seconds the controls are scrambled again whether you touch blue or not, with a red flash and a sound. A row at the bottom of the screen always shows which way each push of the stick will send the ball, so you can keep up if you read it fast. A clock counts down the time, and the high score is kept.

Controls: The stick rolls the ball, though which way each push goes changes during play (hold to keep rolling). On the title, up and down choose and a button starts. Either controller works.
