Bracketeer Tournament Maker

Make seeded tournament brackets, round robin schedules and Swiss pairings with byes, timetables and printable PDFs.

Bracketeer Tournament Maker is a tournament bracket maker for coaches, teachers, clubs, office leagues and gaming nights. It builds single and double elimination brackets for 2 to 128 players or teams with standard seeding (seed 1 meets the lowest seed, seeds 1 and 2 can only meet in the final) and byes placed correctly for any field size, round robin schedules where every pair meets exactly once and nobody plays twice in a round, and Swiss pairings that avoid rematches. Add courts and match length for a full timetable, record results to advance winners and get standings with tiebreakers, and print a landscape PDF bracket or download a CSV schedule.

Swiss pairing follows score groups and seed order, a simplified version of FIDE Dutch rules (no colour allocation or rating floats)
Timetables assume every court is available for the whole event and every match takes the same time
PDF text covers Latin (including Polish and other accented letters), Greek and Cyrillic; Chinese, Japanese, Korean, Arabic, Hebrew and emoji are left out of the PDF (the CSV keeps them)
Records the results you enter; it does not predict winners
