🎯 Select two hands and optional board cards

🧮 50,000 Monte Carlo simulations for accurate equity

📱 Works on desktop and mobile — tap cards to select

Pick two hands and (optionally) some board cards — the calculator runs 50,000 Monte Carlo simulations and reports each side’s equity. While JavaScript loads, the table below covers the most common heads-up preflop matchups so the answer to “AA vs KK” or “AKs vs QQ” is one tap away.

Common heads-up preflop equities (no community cards, average over all suit combinations).
Hand A	Hand B	A win %	B win %	Tie %
AA	KK	81.7	17.8	0.5
AA	QQ	81.5	18.0	0.5
AA	AKs	88.0	11.5	0.5
AA	22	80.4	19.2	0.4
KK	AKs	66.0	34.0	0.0
KK	QQ	81.9	17.6	0.5
QQ	AKs	53.7	46.3	0.0
QQ	AKo	56.6	43.4	0.0
JJ	AKs	54.1	45.9	0.0
TT	AKs	53.6	46.4	0.0
99	88	71.7	28.0	0.3
AKs	22	50.6	49.0	0.4
AKs	QJs	63.8	35.7	0.5
AKo	JTs	59.4	40.4	0.2
AKs	72o	86.0	13.4	0.6
A♠K♠	K♥Q♥	68.5	30.7	0.8

How to read this: “AKs” = ace-king suited, “AKo” = ace-king offsuit, “22” = pocket twos. The famous “coinflip” — pocket pair vs. two overcards — sits right around 50/50; the actual equity favors the pair very slightly (e.g. 22 holds 49.4% against AKs because suitedness gives the overcards an extra 0.5–1% of equity). Numbers above are population averages and round to one decimal place.

How to Use This Calculator

Select Player 1's hand

Tap two cards from the grid. The slot auto-advances to Player 2 after two cards are selected.

Select Player 2's hand

Tap two more cards. After both hands are set, you can optionally add board cards.

Add board cards (optional)

Tap the Board slot, then select 0-5 cards. Leave empty for a preflop equity calculation. Add 3 for flop equity, 4 for turn.

Calculate

Hit Calculate Equity. The tool runs 50,000 random simulations and shows each player’s win percentage plus tie frequency.

About the Math

This calculator uses Monte Carlo simulation — it deals 50,000 random boards and counts how often each hand wins. This gives equity estimates accurate to within about 0.5%. For exact equity (which requires evaluating every possible board combination), you would need a combinatorial solver — but Monte Carlo is fast enough for practical use and runs entirely in your browser.
