Random tournament bracket generator
Press Draw for the first-round matches
Paste the entrants and the first round is drawn at random. If the number is not a power of two, byes are added so the bracket fits; eleven entrants become sixteen slots, so five people go through without playing.
How to draw a bracket
Single elimination needs a power-of-two field, so any other number means byes. The number of byes is the next power of two minus your entrants: eleven needs sixteen slots and therefore five byes. Rounds are log2 of the padded field — sixteen slots is four rounds. In a seeded competition, byes go to the strongest entrants by design; here the draw is entirely random, which is what you want for a social tournament and not what you want for a ranked one.
Questions
A free pass to the second round, given when the field is not a power of two. Eleven entrants in a sixteen-slot bracket means five byes.
Log2 of the padded field: 8 entrants is 3 rounds, 11 needs 16 slots and so 4 rounds.
They are random here. Competitive tournaments deliberately give byes to top seeds, which requires a ranking this tool does not have.
Not until they are played. Later rounds depend on who wins. Draw the first round, play it, then pair the winners.
Yes. Use a seed and anyone can reproduce it.
