How does the poker odds calculator work?

It runs a Monte Carlo simulation: thousands of random boards are dealt from the remaining deck, each one is evaluated, and the win percentage (equity) of every hand is calculated. Everything runs in your browser — no signup, no data sent to a server.

Is the calculator free?

Completely. No signup, no usage limit, no download. It works on both mobile and desktop.

What is equity and how do I read the result?

Equity is the share of the time your hand wins if the hand runs to the river. 65% means you win roughly 65 out of 100 times in that spot long term — it is not a promise about this single hand.

How do I turn this into a decision at the table?

Compare equity to your pot odds. With 100 in the pot and 25 to call you need about 20% equity to break even. More equity than required — call; less — fold.

Does it support Omaha?

The calculator is built around Texas Hold'em. For Omaha maths and the four-card difference, see our Omaha guide.

Can I use it while playing a live hand?

No. Using assistance tools during a live hand breaches ClubGG rules and those of most platforms. Use it for study and post-session hand review.

Reference Table — Common Outs

Draw	Outs	Flop equity	Turn → River
Flush Draw (4 → 5)	9	35.0%	19.6%
Open-Ended Straight	8	31.5%	17.4%
Gutshot Straight	4	16.5%	8.7%
Flush + OESD (Combo)	15	54.1%	32.6%
Two Overcards	6	24.1%	13.0%
Set → Full House / Quads	10	38.4%	21.7%
Pair → Trips	2	8.4%	4.3%
Overpair → Set	2	8.4%	4.3%

The 4/2 approximation: Multiply your outs by 4 on the flop (with 2 cards to come), or by 2 on the turn. It’s a quick estimate — the calculator above gives the exact number.

When does calling actually pay? When your equity exceeds the equity required by the pot odds. Careful — in multiway pots your effective equity drops, and if the opponent can bet more later (reverse implied odds), you need far more.
