Diabolical Dynamics was the game for 2001. The competition consisted of four robots on the playing field for each match, aligned into one alliance. Each alliance worked together to try to score the most points in a two-minute match. This was one of the few games where there was not a competing alliance on the field at the same time. There were 40 small balls, 4 large balls, and 2 7-foot high goals with caster wheels that could be moved around the playing field. One goal started near the Start Zone, the other started near the End Zone, on the opposite side of the field. Dividing the field in half was an 18-inch high railing with a central bridge. Robots passed over the bridge or rails to access the opposite end of the field. The bridge was centrally supported on a beam approximately six inches wide, allowing it to tilt toward either end or remain level.
