Fonz is a 1976 discrete logic motorcycle racing game produced by Sega using the character of Arthur Herbert Fonzarelli from the American television show Happy Days. It runs on the Sega Fonz hardware.

It is a re-branded version of Man T.T. and Moto-Cross. Like those games, Fonz uses a three-dimensional, third-person perspective, with sprite scaling.[1]


The point of the game is to drive a motorcycle as fast as possible on the track without hitting other bikes or skidding off the road; the player receives 10 points per second at the slowest speed and 10 points per half-second at top speed. Passing 1000 kilometers activates extended play. The game is controlled with a motorcycle handlebar interface; players twist to throttle the engine and crashes causes force feedback on the handlebars. Sound in the game is controlled by a tape deck.

This game is the same as Man T.T. and Moto-Cross; the only difference is in the branding of the Fonz character. It is also similar to Road Race, but with motorbikes rather than cars.
