SINGLE VS
DOUBLE
ELIM.

6 MIN READ · BTOP FIELD GUIDE

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:

Cons:

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.

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).

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.
