10 Team Double Elimination Bracket

A different format some leagues use, in which every team is promised at least three games, usually through extra consolation games. This tool makes a standard double elimination bracket, which guarantees every team two games, not three.

A 10 team double elimination bracket has 18 games, or 19 if the grand final reset is played: 9 in the winners bracket, 8 in the losers bracket, and 1 or 2 in the grand final. Every team plays at least 2 games.

Everyone starts in the winners bracket. Seeds 1–6 get a bye through winners round 1, where 2 games are played (8 vs 9 and 7 vs 10). Lose once and you drop into the losers bracket; lose twice and you are out. The winners bracket takes 4 rounds (9 games) and the losers bracket 5 rounds (8 games), with teams dropping in from the winners bracket as it goes. The winners-bracket champion then meets the losers-bracket champion in the grand final, and if the losers-bracket champion wins, a reset game decides the title.

At least 2, because a team is only out after its second loss. The most is 8: a team that drops into the losers bracket early and then wins every game, including the grand final and the reset. An unbeaten champion plays 5 (4 after a first-round bye).

In the order you list the teams, or at random if you choose. Winners round 1 uses standard seeding: 8 vs 9 and 7 vs 10, with seeds 1–6 on byes. Seeds 1 and 2 sit in opposite halves, so they cannot meet in the winners bracket before the winners final. Losers drop into the losers bracket in alternating order, which keeps early rematches to a minimum.

Not with a standard bracket. The winners bracket halves every round, which needs a power-of-two number of slots, so 10 teams sit on 16 slots and 6 teams get a bye. The byes also leave gaps in the losers bracket, which is why it has 5 rounds instead of 6. If nobody should sit out, a round robin gives every team 9 games (45 in total).

The winners-bracket champion reaches the grand final unbeaten and the losers-bracket champion with one loss. If the losers-bracket champion wins, both teams have one loss, so a second game, the reset, decides the title. That is why a 10 team bracket has 18 games, or 19 with the reset. Turn off "Grand final reset" in the setup to make the grand final a single game.

Double elimination takes 18–19 games and every team plays 2 to 8, still giving everyone a second chance. A round robin gives every team the same 9 games and the fairest table, and needs 45 games over 9 rounds. With 10 teams that is a big difference, so double elimination suits a tournament day and a round robin suits a league.
