Team names, results and scores are processed in your browser tab and are not uploaded.
Pick the tool by what you are running. For a knockout, the Bracket Generator makes a single or double elimination bracket from a list of names. When the number of names is not a power of two it gives the byes to the top seeds, and you click the winners as you play. For a league where everyone plays everyone, Round Robin makes the rounds for 2 to 40 teams, single or double, with a bye for an odd number of teams and home and away balanced.
Once scores come in, League Table turns pasted results into standings: played, won, drawn, lost, goals for and against, difference and points, with the points per win set by you. For a fantasy league or a pick-up draft, Draft Order shuffles 2 to 64 teams or managers and lists every pick in snake or linear order for 1 to 30 rounds. On match day, Scoreboard shows big tap-to-score numbers for two to four sides, with sets, undo and full screen.
If you still need the teams, Team Maker splits a list of names into teams and Random Pairs makes pairs or trios; both are linked under More. So are the Stopwatch, Countdown Timer and Interval Timer, which sit in the calculators because they are not only for sport. Everything runs in your browser tab, so team lists and results are not sent to a server.
When the number of names is not a power of two, the bracket is filled up with byes, and the top seeds get them. With 6 names there are 2 byes, for seeds 1 and 2, and the other four teams play in round 1.
A single round robin of 8 teams has 7 rounds of 4 matches, 28 in all, and a double one has 14 rounds and 56 matches. With 9 teams one team sits out each round, so there are 9 rounds of 4 matches.
Teams level on points, such as two on 12, are ranked by difference (for minus against), then by goals for, then by the points and difference from the matches between the level teams only, then by name A to Z. Bonus points and shootout results are not supported, and the standings cannot be edited in the tool, so copy them elsewhere to adjust points or order.
