Rumble

From Combat Robot

A rumble is a generic term for a combat robot fight with more than two (often many more) robots fighting simultaneously in the same arena. Traditionally, the rumbles happen at the end of the tournament and are open to any 'bots still running that can find a clear radio frequency. Rumbles are usually held by weight class. The winner is often determined by audience cheering at the end.

Rumbles are sometimes referred to as 'melees'.
