The most common question we get from operators setting up their first tournament: "What's the difference between single and double elimination, and which should I pick?"
Short answer: single elim if you want it done fast; double elim if you want it to feel fair. The longer answer is below.
Single elimination
Lose once, you're out. The bracket is a binary tree — a 16-player single-elim has 15 total matches: 8 in round 1, 4 in round 2, 2 in semis, 1 final. Every match eliminates exactly one player.
Pros:
- Fast. An 8-player single-elim wraps in about 45 minutes on one table. 16-player on two tables, ~90 minutes.
- Simple to explain. Lose, you're out. Done.
- Drama at every match. Every loss eliminates someone, so stakes are high from the first round.
Cons:
- Unlucky early matchups can knock a strong player out fast. First round draws sometimes pit the two best players against each other; the loser exits without a real chance to prove themselves.
- No second chance. Players who travel to your tournament might play one match and be done in 15 minutes. That's a tough sell for a $5-cover league night.
Double elimination
Lose once, drop to the losers bracket. Lose twice, you're out. Every player is guaranteed at least two matches before they're eliminated. The bracket has two halves — winners and losers — that converge in a grand final.
Pros:
- Fairer. Bad early matchups don't end your night. Players have to actually be beaten by two different opponents (or the same one twice) to be eliminated.
- More games per player. Double the play time per dollar of entry fee.
- Compelling losers-bracket runs. A player who loses early but wins seven straight in the losers bracket to make the grand final is a real story. Some of the best tournament narratives come from these comeback paths.
Cons:
- Roughly 2× the matches. A 16-player double-elim has ~30 matches vs ~15 in single. You need more time, more table-hours, or more tables running in parallel.
- The grand-final reset rule confuses everyone the first time. See below.
The grand-final reset rule
This is the rule that trips up new operators. Here's what it actually means:
The winners-bracket champion enters the grand final having never lost. The losers-bracket champion has lost exactly once. If they meet in the grand final and the losers-bracket player wins — that means the winners-bracket player has now lost once, same as everyone else who's been eliminated.
In a true double elim, you have to lose twice to be eliminated. The winners-bracket champion has only lost once. So they get one more shot — the "reset" match.
If the winners-bracket player wins the first grand final, they're champion (the losers-bracket player has now lost twice — once getting to losers bracket, once in grand final). Done.
If the losers-bracket player wins the first grand final, you play a second match. Whoever wins that one is the champion.
BTop has a checkbox for "grand final reset" in the setup form. Leave it on for a true double elim. Turn it off if you want a single grand-final match regardless (some leagues prefer this for time reasons).
How to choose
Pick single elim if:
- You're running a quick weeknight tournament (under 2 hours).
- You have one or two tables and 16+ players.
- The vibe is casual — friendly competition, not a league night.
- It's the first tournament at this venue and you want to see how it goes before committing more time.
Pick double elim if:
- You have plenty of time (3+ hours) or a dedicated tournament evening.
- You have 3+ tables to run matches in parallel.
- It's a league night where players are paying meaningful entry fees.
- You want comeback stories and longer player engagement.
Pricing note
BTop free tier covers single elimination. Double elimination is a premium feature ($9.99 token) — except during the launch promo (until Dec 14, 2026) where it's free for everyone. After that, $9.99 per tournament unlocks double-elim plus all other premium features (multi-table, long races).
If you're on the fence, run your first tournament as single elim for free. If your players ask for "more matches each" afterwards, switch to double next time.
