When players pocket more than one ball on a single at any time, a situation often arising on the , they may shoot at any companion balls, but must pocket each in succession in any order. If incidental balls are pocketed on the same stroke that a cribbage is completed, they add to the succession of cribbages the player is "on". When a player fouls by failing to pocket an unpaired cribbage while on a succession of unpaired balls, only unpaired balls are spotted; the prior successful cribbages count toward the score.
