Each match of Rack 'n Roll is 2 minutes 15 seconds long, divided into three segments. The first segment is a 15 second autonomous period, where robots may attempt to place keepers onto the rack without human input. Once autonomous mode is complete, any keepers not already on the rack are no longer valid for scoring. The second segment, the teleoperated mode, is 2 minutes long, during which robots are operated by the drivers and may roam anywhere on the field. In the final 15 seconds, the end game, robots may not enter their opponent's end zone, but all other rules remain the same from the teleoperated period. Though the head referee may pause the game between the autonomous period and the teleoperated period, the end game follows directly after the teleoperated period.
