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 Once autonomous mode is complete, any keepers not already on the rack are no longer valid for scoring.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.

 

The primary method of scoring in Rack 'n Roll is by making rows and columns of tubes on the rack. A row or column of n tubes is worth 2n points to a maximum of n=8. Note that this includes rows or columns of length 1, so a single tube on the rack that does not form a row or column is worth 2 points. Teams have access to 21 scorable keepers and ringers. This means that the maximum possible score from the rack should be 596 . That is, two rows of 8 ringers, a row of 5 (2 ringers plus 3 keepers), 5 vertical columns of length 3, then 3 vertical columns of length 2.

 

As is usual in a FIRST game, robot positions at the end of the match are worth bonus points. In Rack n' Roll, each robot in its alliance end zone that is not touching any field element and has its lowest part 4 or more inches off the ground will score 15 bonus points. A robot that is not touching any field element and has its lowest part 12 or more inches off the ground will score 30 bonus points. Since robots may not be touching any field element, this means that in order to score bonus points, teams will have to depend on their alliance partners to provide mechanisms to lift their robots or will have to have mechanisms to lift their alliance partner's robots. Since at least one robot must be touching the ground in order to lift the other two alliance robots off the ground, the maximum conceivable bonus points an alliance can score is 60 points.
