Dexterity games, especially during the 1960s, took many unusual and innovative shapes. Hasbro took a classic balancing toy, based on a circus high-wire act, and created a game. Players compete by spinning a spinner and thereby raising or lowering their side of the high-wire stand. This causes the balancing clown on the wire to frantically pedal his unicycle backwards or forwards, depending on the wire's new slope. A pretty simple concept, the game involves complex plastic parts to work successfully.
