Tournament Bracket Generator: Build a Bracket Free
Paste your teams or players, choose seeded or random, and generate a single-elimination bracket. Byes are added automatically when your count isn't a power of two.
A tournament bracket generator builds a single-elimination bracket from your list of teams or players. Paste the entrants, choose seeded or random, and generate. The tool sizes the bracket, adds byes when your count isn’t a power of two, and lays out every round through the final. Print it or copy it as text, then mark winners as the games finish.
You’ve got a bracket. Here’s how seeding and byes work, and how to run the event.
How to build a bracket in three steps
- Paste your entrants. Teams or players, one per line or comma-separated. Duplicates get removed.
- Choose the order. Random shuffles everyone into the bracket, or keep your typed order as seeds so the top seed meets the lowest.
- Generate. The tool builds the full bracket, adds byes if needed, and shows every round through the final.
Here’s an 8-team single-elimination bracket:
Quarterfinals
- ChloeElla
- AvaGrace
- HugoDiego
- BenFinn
Semifinals
- ByeBye
- ByeBye
Final
- ByeBye
What byes are and when you get them
A single-elimination bracket works cleanly when the number of entrants is a power of two: 2, 4, 8, 16, 32. When your count sits between those, some entrants get a bye, which means they skip the first round and go straight to the second.
Say you have 6 teams. The nearest power of two above 6 is 8, so the bracket has 8 slots and 2 of them are byes. Two teams advance without playing round one, and the other four play to join them. Seeding decides who gets the byes: the top seeds do, so the strongest teams aren’t knocked out early by the bracket math.
Here’s a 6-team bracket showing how the two byes land:
Quarterfinals
- BenBye
- FinnChloe
- AvaBye
- EllaDiego
Semifinals
- BenBye
- AvaBye
Final
- BenAva
Seeding vs random
Seeded puts your best teams apart so they can’t meet until late rounds. Type entrants strongest to weakest and the tool pairs top against bottom in round one. This is what you want for a competitive event where you don’t want the two favourites clashing in the first game.
Random ignores strength and shuffles everyone in. Fair, fast, and good for casual events or when you don’t have rankings. It uses the same unbiased Fisher-Yates shuffle as the rest of the site, so no entrant is favoured.
Running the event
Once the bracket is built, print it for a wall or copy it as text to drop into a chat or doc. As games finish, mark each winner and move them into the next round, all the way up to the final. Byes are already filled in, so the teams with a bye start in round two.
To build the teams that enter the bracket, use the team generator first. For a class or PE tournament, split the room with the PE team generator, then bring the teams here. Need names for the entrants? The team name generator and cool team names list have you covered.
Frequently asked questions
How does the tournament bracket generator handle odd numbers of teams?
It rounds up to the next power of two and fills the empty slots with byes. A bye means a team skips round one and advances automatically. So 6 teams go into an 8-slot bracket with 2 byes, and 10 teams go into a 16-slot bracket with 6 byes. Seeding decides which teams get them.
What’s the difference between seeded and random brackets?
Seeded uses your typed order as strength, pairing top against bottom so the favourites can’t meet until later rounds. Random shuffles everyone in without regard to strength, using an unbiased method. Choose seeded for competitive events where you want fair matchups, and random for casual events or when you don’t have rankings.
Who gets a bye in the bracket?
The top seeds. When byes are needed, the tool gives them to the highest-ranked entrants, so the strongest teams aren’t eliminated early just because the numbers didn’t divide evenly. If you chose a random bracket instead of a seeded one, the byes fall to whoever the shuffle placed in those slots.
Can I print or copy the bracket?
Yes. You can print the bracket to put on a wall for players to follow, or copy it as plain text to paste into a chat or document. Print or copy it once the matchups look right, then mark winners round by round as the games finish.
Does it do double elimination?
This tool builds single-elimination brackets, where one loss knocks you out. Single elimination is the fastest format and suits most casual tournaments and class events. For a longer event where you want teams to have a second chance, you’d run two single-elimination brackets, a main and a losers’ side.
