How the 12-team basketball double elimination bracket is built
12 is not a power of two, so the bracket is padded to 16 slots and the top 4 seeds skip round one with a bye. Everyone gets two lives: losers from the winners bracket drop into a 6-round losers bracket. The grand final is 22 games in, and if the losers-bracket finalist wins it a reset game is played, for 23 games in total.
First-round matchups
Standard seeding puts the strongest seed against the weakest: 8 v 9, 5 v 12, 7 v 10, 6 v 11. Seeds 1–4 wait for round two. List your teams strongest-first in the generator and the seeding is applied automatically.
How long does it take?
With 60-minute games, 23 games take about 23 hours on one court and 11.5 hours on two — but rounds can't overlap, so the last rounds always run one game at a time. Pro's scheduler enforces that ordering when it assigns dates, start times and courts.
Basketball rules that affect the schedule
Rec-league basketball games usually run two 20-minute halves with a running clock, so a 60-minute slot including warm-up and changeover is realistic. Ties are broken with overtime, so standings use a simple 2-points-per-win system.
Tie-breakers: Head-to-head record, then point differential (often capped at ±20 per game to discourage running up the score), then points scored.
Organizer tip: Give each team at least 60 minutes between games on the same day; back-to-back games are the most common complaint from players.
