Lunacy is played on a rectangular field that is 54' by 27'. This field floor is referred to as 'Regolith'. The regolith is designed to interact with robots, which must use a special mandatory wheel that may not be altered, to have reduced traction. This is supposed to mirror the effect of driving with low gravity on the moon.
Lunacy is played by two alliances of three robots each. The objective of the game is to score points by placing moon rocks (worth 2 points when scored) in the opposing alliance's trailers, which are dragged around by each robot. Empty cells (worth 20 points when scored) may be delivered to human players to be used later as "super cells". During the last 20 seconds of a match, supercells (worth 15 points when scored) may be put into play.
