 Since the introduction of pool play in 2018, one-game playoffs occur if teams are tied between fourth and fifth place in the pool stage (which determines qualification for the Championship Pool) and again if teams are tied between fourth and fifth place in the Championship Pool (which determines qualification for the playoffs).Unlike other pool stage games, tie-breaker results are not carried over by the winning team(s) to the Championship Pool.Since the introduction of pool play, if the quotient of number of teams tied for multiple qualifying berths divided by the number of qualifying berths available is less than two, then the teams' last stone draw records are used to determine which team(s) advance(s) without having to play (a) tie-breaker game(s).
