Multiway / tournament calculators

Everything here is what can be computed exactly in your browser for multiway pots and tournaments.

Computes exact equity for pots involving 3 to 6 players by Monte-Carlo simulation from hands or ranges plus the board. Equity is the probability of winning at showdown, so it can be computed exactly no matter how many players are involved.

① Player hands / ranges

A specific hand (e.g. AhKs) or a range (e.g. AA,AKs,QQ+ / JJ+) work too. Blank fields are ignored.

② Board (optional)

③ Precision

Converts tournament chips into prize expectation ($EV) (ICM = Independent Chip Model). You can only win first place once, so chip value is non-linear — and that is what makes the game non-zero-sum and breaks the two-player GTO guarantee. This is exactly why play tightens up under ICM. The prize expectation itself can be computed exactly (Malmuth-Harville).

① Chips per player

② Payouts (from the top)

For short stacks (roughly 15bb and under), the heads-up “open-shove or fold” decision isNash equilibrium, because every hand ends all-in — pure equity, with no postflop left to play,This is two-player zero-sum — the one spot in real play where exact GTO is defined. Shows the SB (button) shove range and the BB calling range.
