Poker odds chart quick answer

The poker odds numbers most players need are simple: a flush draw has 9 outs and is about 35% to hit by the river, an open-ended straight draw has 8 outs and is about 31.5%, and a gutshot has 4 outs and is about 16.5%. For a fast table estimate, multiply your outs by 4 on the flop or by 2 on the turn.

Flush draw: 9 outs, 19.1% to hit on the turn, 35.0% by the river.
Open-ended straight draw: 8 outs, 17.0% to hit on the turn, 31.5% by the river.
Gutshot straight draw: 4 outs, 8.5% to hit on the turn, 16.5% by the river.
Two overcards: 6 outs, 12.8% to hit on the turn, 24.1% by the river.

Flush Draw

9 outs

Flop to river:35.0%

Turn only:19.1%

River only:19.6%

Pot odds needed:1.9:1

Four cards to a flush after the flop. The most common draw in poker with a roughly 1 in 3 chance of completing by the river.

Open-Ended Straight Draw

8 outs

Flop to river:31.5%

Turn only:17.0%

River only:17.4%

Pot odds needed:2.2:1

Four consecutive cards that can be completed at either end. Slightly less likely than a flush draw but still a strong drawing hand.

Gutshot Straight Draw

4 outs

Flop to river:16.5%

Turn only:8.5%

River only:8.7%

Pot odds needed:5.1:1

An inside straight draw needing one specific card rank. Needs large pot odds to call profitably, but can win big pots when it hits.

Two Overcards

6 outs

Flop to river:24.1%

Turn only:12.8%

River only:13.0%

Pot odds needed:3.1:1

Holding two cards higher than any card on the board. Pairing either overcard may give you the best hand, though beware of stronger draws.

The Rule of 2 and 4

The Rule of 2 and 4 is a quick mental shortcut for estimating your chances of hitting a draw. Instead of doing exact probability calculations at the table, you can get a close approximation in seconds.

Rule of 2 (One Card to Come)

Multiply your number of outs by 2 to estimate the percentage chance of hitting on the next card. Use this on the turn when only one card remains.

Example: 9 outs x 2 = 18% (exact: 19.1%)

Rule of 4 (Two Cards to Come)

Multiply your number of outs by 4 to estimate the percentage chance of hitting by the river. Use this on the flop when both turn and river remain.

Example: 9 outs x 4 = 36% (exact: 35.0%)

When It Breaks Down

The Rule of 4 becomes less accurate with higher out counts. At 15+ outs, the approximation starts to overshoot noticeably. For example, 15 outs x 4 = 60%, but the exact probability is 54.1%. For very high out counts, consider using the exact percentages from the chart above or adjusting the Rule of 4 result down by a few points.

Toggle the "Rule of 2 and 4" comparison in the table above to see how the approximation compares to exact math for every out count from 1 to 20.

Note: All calculations assume a standard 52-card deck with no additional information about folded or exposed cards. Actual probabilities at the table may vary slightly based on known cards.

The numbers you should have memorized by now (and the ones you should not bother with)

There are about twenty numbers in poker that actually matter during a hand. Not the exact probabilities down to the decimal, but the ballpark. You have a flush draw? Around 35% to get there by the river with two cards to come. Open-ended straight draw? Roughly 32%. Gutshot? About 17%. Those three cover most of the drawing situations you will face, and if you know them cold, you are ahead of most players at low and mid stakes.

The temptation is to memorize the entire chart. All twenty outs, both streets, exact percentages. Do not bother. Your working memory has limits, and the middle of a hand is not the time to recall that 13 outs gives you 27.7% on the turn specifically. What you need is the "Rule of 2 and 4": multiply your outs by 4 with two cards to come, or by 2 with one card to come. It is close enough for table decisions and it works in your head in under a second.

The chart above includes a toggle to compare the Rule of 2 and 4 against exact math. The approximation works well for low out counts (under 10 outs, it is within a percentage point or two). Once you get past 12 outs, the shortcut starts to overestimate your chances. A 15-out monster draw is not quite 60% as the rule suggests. It is closer to 54%. That gap matters when the pot is large and the difference between calling and folding is real money.

The pot odds cross-reference is where this chart earns its keep. Knowing you have 35% equity with a flush draw is half the equation. The other half is knowing what price the pot is giving you. If someone bets half the pot, you need about 25% equity to call profitably. Your flush draw clears that easily. If they bet the full pot, you need 33%. Still fine. If they overbet to twice the pot, you need 40% and suddenly that flush draw is a fold. The chart puts both halves together so you can see the relationship without doing division under pressure.

A practical way to use this: before your next session, look at the chart and pick out three common scenarios you face regularly. Maybe it is the flush draw, the gutshot, and the overcards situation. Note the equity for each one and the pot odds threshold. Write them on a sticky note if you want. During the session, when one of those situations comes up, you will not have to think. You already know the answer.

The numbers do not change between crypto rooms and traditional rooms. A flush draw has 9 outs on every site running standard Hold'em rules. What changes is the bet sizing patterns. Some crypto rooms have faster action and larger default bet sizes, which affects the pot odds side of the equation. But the outs and hit percentages? Those are constant. Learn them once and they are valid everywhere you play.

Skip the obscure edge cases. Nobody needs to know the exact probability of hitting a running two-pair with 4.5 effective outs. Focus on the twelve rows in the chart that map to draws you actually see: 4, 6, 8, 9, 12, and 15 outs. That covers gutshots, overcards, straight draws, flush draws, and combo draws. Everything else is too rare to be worth the mental real estate.

Odds Chart questions

What is the rule of 2 and 4 in poker odds?

The rule of 2 and 4 is a shortcut for estimating draw odds. On the flop, multiply your outs by 4 to estimate your chance of hitting by the river. On the turn, multiply your outs by 2 to estimate your chance of hitting on the river.

How many outs does a flush draw have?

A standard flush draw has 9 outs because there are 13 cards in each suit and you can already see 4 of that suit between your hand and the board. With two cards to come, that draw hits about 35% of the time.

What pot odds do I need to call a flush draw?

With a normal 9-out flush draw and two cards to come, you want roughly 35% equity or better. Calling a half-pot bet usually needs about 25% equity, a pot-sized bet needs about 33%, and a two-times-pot overbet needs about 40%.

Which poker outs should beginners memorize first?

Start with 4 outs for a gutshot, 6 outs for two overcards, 8 outs for an open-ended straight draw, 9 outs for a flush draw, 12 outs for a combo draw, and 15 outs for a strong flush-plus-straight draw.
