How to use it
Press a card slot, then pick its card from the deck. A card in play is greyed out everywhere else, so the same card cannot be dealt twice. Press "Use a range" to give a seat a range such as QQ+, AKs instead of two cards. Add up to nine seats and up to five board cards.
With few cards left to deal the calculator counts every board. Before the flop there are too many, so it samples boards with a fixed seed. A shared link gives the same inputs and repeatable estimates. Copy the link under the results to post a hand in a forum or a chat.
Worked poker odds: load these hands
Each example names both hands and every known board card. The percentage is the first hand's share of the pot, including ties. Suits matter: a different suit can add or remove a draw.
| Situation | Hands and board | |
|---|---|---|
| Flush draw against top pair | 7c6c vs AsKd, board AcJc2d | About 37% |
| Open-ended straight draw against top pair | JhTs vs AsQd, board Qh9d3c | About 34% |
| An ace-high straight on the board | 2c3d vs 4c5d, board TsJdQhKcAh | 50% |
Card notation gives rank then suit: T is ten; s, h, d and c are spades, hearts, diamonds and clubs. For example, 7c6c is the seven and six of clubs.
Flush draw against top pair: Two clubs in your hand and two on the flop give a flush draw. The opponent has a pair of aces; later pairs, straights and full houses can change who wins, so counting clubs alone does not give showdown equity.
Open-ended straight draw against top pair: A king or an eight completes the straight, but pairing a jack or ten is not enough to beat a pair of queens. The calculation checks the whole two-card runout, including redraws and ties.
An ace-high straight on the board: Both players use the five board cards. Neither wins outright; both tie, and each receives half the pot. A tie percentage and a share of the pot describe different things.
Why win percentage and equity can differ
A board-only straight is a useful check: both players tie on every deal, neither wins outright, and each has . With more than two players, the share of a tied pot depends on how many players tie. Use the result's to understand the outcomes, and equity to compare shares of the pot.
What the calculator assumes
The calculation deals the remaining cards fairly from the unseen deck and uses the hands or ranges you enter. It does not predict an opponent's range from their betting, choose a bet size or account for future folds. If your assumed range is wrong, an exact calculation can still answer the wrong question.
The results say whether they are exact or sampled. An exact result counts all permitted deals. A is an estimate with a fixed seed; it is reproducible for the same inputs, rather than a guarantee of the next hand's outcome. Do not treat a small sampled difference as a precise edge.
Odds, equity and the price of a call
Win and tie are counts of boards. Equity adds half of every two-way tie and is your share of the pot if the cards were run out. Compare it with the , which the pot odds calculator works out from the pot and the bet. For one range against another, use the equity calculator; for listed preflop matchups on their own pages, see preflop matchups.
