Rack n' Roll was the 2007 First Robotics Competition game, this game consisted of three dimensional pool toys which were known as keepers, ringers, and spoiler. Keepers were the pool toys that are scored during autonomous mode. Ringers are undecorated tubes that are delivered onto the field either by human players through chutes or can be swiped up from the floor. Nine ringers are placed on the opposing alliances side in the beginning of the match, the rest of the ringers stay with the human player. Spoilers are colored black and cause the arm holding them to be ignored for scoring purposes. Spoilers can be removed or repositioned on the rack by robots multiple times
