The Unit Round Robin is played in two phases: the round robin phase (in which each team in each league plays every other team in the league) and a playoff phase (in which teams that score high enough to qualify play in a knockout to determine the winner of each flight. The time and place of matches isdetermined by the participants (most matches are played at players' homes). Registration for the Round Robin is held in the spring. There are separate Flight A and Flight B round robins, with a Flight C round robin if there is sufficient participation.
