Systems of play

The Page playoff system is a playoff format used primarily in softball and curling at the championship level. Teams are seeded using a round-robin tournament and the top four play a mix of a single-elimination and double-elimination tournament to determine the winner.

The system requires teams to be ranked in some way, as the top two teams have an advantage over the bottom two. This is usually accomplished through a round-robin tournament, which eliminates all but the top four teams.

A single-elimination tournament, also called a knockout, cup or sudden death tournament, is a type of elimination tournament where the loser of each match is immediately eliminated from winning the championship or first prize in the event.

The round in which only eight remain at the start it is generally called the quarter-final round; this is followed by the semi-final round in which only four are left, the two winners of which then meet in the final.

A round-robin tournament or all-play-all tournament is a type of tournament in which each contestant meets all other contestants in turn. In a single round-robin schedule, each participant plays every other participant once. If each participant plays all others twice, this is frequently called a double round-robin.
