Demolition Derby is a 1 - 2 player arcade game for the TRS-80 CoCo. The player controls a small vehicle from a top-down perspective, that can move in all directions. The goal is to push competing cars into the walls on the side of the racetrack. The player can use gas guzzling turbos to smash other vehicles harder. Each vehicle bumped into the wall increases a meter on the right side of the screen, allowing the player to move onto a more difficult track. If the player hits the side or stationary obstacles, they are destroyed. Levels must be completed before fuel runs out, and players starts with 3 cars.
