How to Use the Calculator

Deal each player's hole cards and the board, press Calculate, and you'll see everyone's win, tie, and equity percentages — plus a hand-odds breakdown and the exact outs each player needs. This guide covers every part of that, step by step. The whole tool runs in your browser; nothing you enter is sent anywhere.

1. Deal each player's hole cards

Every player has two hole cards. Tap an empty card slot in a player's seat to open the card picker, then choose a rank and suit. Cards already in play elsewhere are disabled in the picker, so you can't accidentally deal the same card twice. To change a card, tap it and pick a new one; to empty a slot, use the small ✕ on a filled card.

2. Add or remove players

The calculator supports 2 to 10 players. Use Add player to seat another hand and the remove control on a seat to take one away. You don't have to fill every seat — a seat with no cards is simply left out of the calculation. This makes it easy to model "what if a third player were in this pot?" scenarios.

3. Set the community board

The five shared community cards are the flop (first three), the turn (fourth), and the river (fifth). You can leave the board empty to evaluate a pre-flop situation, or fill in as many cards as you like:

• The three flop cards can be set at any time.
• The turn unlocks once the flop is complete.
• The river unlocks once the turn is set.

Clearing a flop card also clears the turn and river, since a board can't have gaps. This mirrors how a real hand is dealt, street by street.

4. Calculate

Press Calculate once at least two players hold a full two-card hand. (The button stays disabled if any player has only one card — half-entered hands are ambiguous.) The calculator then works out each active player's chance of winning the pot.

5. Read the results

Each player in the hand gets:

• Equity — the player's overall share of the pot, combining outright wins and split pots. Equities across all active players add up to 100%. The current leader is highlighted.
• Win and tie — how often the player wins outright versus chops the pot with someone else.
• Hand odds — a breakdown of how often the player ends up with each hand type, from a Royal Flush down to High Card. Open it to see, for example, how often a flush draw actually completes.

6. Outs and the verdict

Below the equities, the calculator gives each player an outs verdict based on the cards still to come:

• Leading — currently the equity favourite.
• Outs — the specific cards that would make this player the favourite, listed out.
• Needs two — only a specific pair of running cards can rescue the hand.
• Drawing dead — no remaining card can give this player the lead.

"The lead" here always means the equity lead, so the verdict never contradicts the percentages shown. See Poker Odds & Probability for how to count outs yourself.

7. Exact vs. Monte Carlo

A small badge tells you how the current numbers were produced. Once the flop is out, the calculator usually computes the result exactly by checking every possible way the rest of the board can come — these figures are precise and identical on every run. For very large situations (typically pre-flop), it instead runs a Monte Carlo simulation of up to a million random boards; those numbers are statistical estimates accurate to well under a tenth of a percent, so they may wobble slightly between runs. The outs verdict and hand-odds breakdown are always computed exactly.

Tips

• Set up a pre-flop matchup with an empty board to study classic spots like a pair versus two overcards.
• After calculating, click through turn and river cards to watch equity swing in real time.
