Make a tournament bracket in the chat, record results by clicking the winners, and print it. Tournament bracket maker: single elimination and double elimination brackets for 2 to 128 players or teams. Standard seeding puts seed 1 against the lowest seed, so seeds 1 and 2 can only meet in the final; when the field is not a power of two (a bracket for 6, 10 or 12 teams), the byes go to the top seeds and are placed exactly where a seeded bracket needs them. Add a third-place match, or use double elimination with a losers bracket and a grand final with an optional reset match. Seeding can follow your ranking, a reproducible random draw, or the order you list. Round robin schedule generator: everyone plays everyone exactly once (or home and away), nobody plays twice in a round, one team sits out each round when the number is odd, and home and away games are balanced. Swiss pairings: players with the same score meet each round, with no rematches whenever they can be avoided, and a fair rotation of byes. Timetable: give the number of courts, tables or fields, the match length and the start time to get a start time and court for every match and the finish time of the event. Results and standings: tell it who won, or click a player in the bracket, and winners advance, the next matches appear and the champion and final places are shown. Round robin tables use points, then head-to-head, then score difference; Swiss tables use Buchholz. Print and share: a landscape PDF bracket that stays readable up to 64 players, with an order-of-play page, and a CSV schedule for spreadsheets. For coaches, teachers, clubs, office leagues, school sports days and gaming nights. Limitations: up to 128 participants; round robin up to 500 matches; Swiss pairing is a simplified score-group method without chess colour allocation; timetables assume equal match lengths.
