Tournament bracket generator

In a round robin every team plays every other team once. The schedule is built with the circle method (also called the Berger method): one team stays fixed and the others rotate each round, so nobody plays twice in the same round and every pairing appears exactly once.

With n teams there are n × (n − 1) ÷ 2 games. With an odd number of teams, one team sits out each round (a bye), and everyone gets exactly one bye. Tick Double round robin for a home-and-away season: the second half repeats every game with the sides swapped.

In a knockout bracket, the loser of each game is out, and the winner advances until one champion is left. The bracket needs a power of two (4, 8, 16, 32, 64), so if you have, say, 12 teams, the first round is padded to 16 and four teams get a bye straight into the second round. Each first-round pairing gets at most one bye, so from round two on every slot is a real game.

Rounds are labeled the way US sports fans expect: Round of 32, Round of 16, Quarterfinals, Semifinals and Final. Later rounds show placeholders such as "Winner of match 3" so you can fill in results as you go.

In a double elimination bracket, nobody is out after one bad game. A first loss drops you into the losers bracket, and a second loss ends your run. The losers-bracket winner meets the winners-bracket champion in the grand final; if the losers-bracket team wins it, both have one loss, so a reset match decides the title.

The bracket runs the whole event, not just the draw. Click the name of whoever advances and they move to the next round; in double elimination the loser drops into the losers bracket automatically. Click again to undo a mistake. Single elimination can include a third-place game.

In a round robin, type each score and the standings table updates as you go: games played, wins, draws, losses, goal difference and points (3 for a win, 1 for a draw).

Your bracket and results are saved in your browser. Print it for the gym wall, or send a share link that includes the current results.

With Random draw (shuffle seeding) ticked, the order of your list is shuffled before the schedule is made, which is fair when teams have no ranking. Untick it to use your list order exactly. In a bracket, that means the first two teams on your list meet in the first game, the next two in the second, and so on; if you want the top seeds kept apart, arrange the list yourself in bracket order.

A popular hybrid is pool play followed by a playoff: split teams into groups with the random team generator, run a round robin in each group, then put the group winners in a bracket.

Copy the schedule or the first round as plain text and paste it into an email, a group chat or a spreadsheet. The tool supports 2 to 128 participants, and every name must be unique. All of it runs in your browser; nothing is stored or uploaded.
