Screwball Scramble is a toy made by Tomy that involves guiding a 14-millimeter-diameter chrome steel ball bearing around an obstacle course. A player guides the ball by using various buttons, dials and levers that affect parts of the course. If a mistake is made a player must start again. The aim of the game is to complete the course as fast as possible. It takes no batteries and is recommended for children five and above. The toy was popular during the 1980s, and is still available today
