9 team double elimination bracket

Nine entrants, two lives each: 8 matches in the winners bracket, 7 in the losers bracket over 6 rounds, and a grand final. Type your names over the sample ones and print both trees.

9 entrants in a 16-slot double-elimination draw: 8 winners-bracket matches, 7 losers-bracket matches across 6 losers rounds, and the grand final — 16 in all, or 17 if the bracket is reset. 7 byes to the top 7 seeds, which leaves 7 losers-bracket boxes nobody can ever fill.

Top box: the entrant who arrives undefeated. Bottom box: the one who arrives out of the losers bracket, already carrying a loss. The second match is played only if the undefeated entrant loses the first — at that point they have lost once, and one loss does not eliminate anybody in this tournament.

What 9 teams look like in two brackets

Nine entrants sit in a 16-slot draw, so the winners bracket runs 4 rounds — round of 16, quarter-finals, semi-finals and final — and the losers bracket runs 6 behind it. The sheet carries 15 winners boxes and 14 losers boxes, plus the grand final that joins them.

Everybody except the champion has to lose twice, which fixes the total at 16: 8 winners-bracket matches, 7 losers-bracket matches and one grand final. Single elimination for the same 9 entrants is 8, so the second chance costs 8 extra matches. That ratio holds at every size and it is the only honest way to budget the day.

Seven of the 16 slots are empty, so seven of the 9 entrants skip round one. They are the top seven seeds, because a bye is one fewer match to win and that belongs to whoever earned the seeding. On a single-elimination sheet that is the end of the matter. Here it also punches seven holes in the losers bracket, which is the part nobody expects.

The 9-team losers bracket, round by round

The 6 losers rounds are 4, 4, 2, 2, 1, 1 boxes wide — 14 boxes in all, of which 7 are played at 9 entrants. They come in pairs: an odd-numbered round takes a fresh batch of beaten entrants from the winners bracket, and the round after it folds the survivors together. Beaten entrants therefore arrive on a timetable — quarter-final losers join at losers round 2, semi-final losers join at losers round 4 and the beaten winners finalist joins at the losers final.

Losers round 2 is 4 boxes wide and it is the one that goes wrong. Drop winners match 1 into losers box 1 and an entrant meets the person who has just knocked them out about half the time, which is precisely what the second life was for. The losers are dropped in reversed here instead, and at 9 entrants that makes the rematch impossible in that round.

Seven of the 14 losers boxes cannot be played at all. Three of those have nobody on either side and drop out of the tournament entirely: 9 entrants in a 16-slot draw simply do not generate enough first-round losers to fill the opening losers round. The rest are walkovers, marked as such.

Running a 9-team double elimination

16 matches at a quarter of an hour each is about 4 hours of court time. On one court that is a long session; the losers bracket is where the time goes, because 7 of the 16 matches happen in it and none of them can start until the winners round above has finished.

Decide before anybody plays whether the grand final can be reset. If it can, the schedule is 16 matches with a 17th held in reserve. If it cannot, an entrant can win this tournament having lost once, against somebody who has lost nothing — defensible, but only if it was said at the start rather than after the 16th match has gone the wrong way.

15 winners boxes and 14 losers boxes will not share one A4 sheet legibly: 30 boxes carrying 16 matches for 9 entrants. Print the two brackets as separate landscape sheets and pin them side by side, which is how they get used anyway — the winners bracket is watched and the losers bracket is administered.

Common questions

How many matches in a 9 team double elimination bracket?

16, or 17 if the grand final is reset. 8 of them are in the winners bracket and 7 in the losers bracket, because every entrant but the champion has to lose twice and 9 entrants therefore absorb 16 losses.

How many rounds is a 9 team double elimination tournament?

4 winners rounds and 6 losers rounds, then the grand final — 16 matches for 9 entrants. The losers bracket needs roughly twice as many rounds because it folds in a fresh batch of beaten entrants after every winners round: quarter-final losers join at losers round 2, semi-final losers join at losers round 4 and the beaten winners finalist joins at the losers final.

Where do the byes go in a 9 team double elimination bracket?

To the top seven of the 9, the same as single elimination — but with a second consequence here. Seven of the 14 losers boxes then have no loser coming, because a walkover produces none, so they are marked unplayable on the printed sheet rather than left looking live.
