What Is a Flush Draw? (And How Often It Hits)
Level 3 · Lesson 2 of 53 min read
What does a flush draw look like?
Two hearts in your hand, two more on the flop:
It is the most common of the draws worth knowing.
One heart in your hand and three on the board counts too, but it is the weaker version. Three hearts showing is visible to everyone, so opponents are far likelier to hold the fourth — and if the suit arrives, several players may table a flush at once.
How often does a flush draw hit?
Count the cards that complete you. Thirteen hearts exist and you can see four, so 9 are left — nine outs, the cards that turn the draw into a made flush.
Each out is worth roughly 2% per card to come. Two cards are coming, so double it:
9 outs × ~4% ≈ 36%
Round to ~35%. Better than one in three, which is more than most players assume when they fold.
Among the common draws that is the best number available. An open-ended straight draw arrives ~32% of the time and a gutshot ~17% — same counting method, fewer outs.
That ~35% only holds from the flop, where two cards are still coming. Miss the turn and you run the count again with one card left:
9 outs × ~2% ≈ 18%
The hand hasn't weakened. It has one chance left instead of two, which is why the same draw can be worth continuing on the flop and worth folding on the turn.

What can go wrong with a flush draw?
Your flush can lose to a bigger one. Every player at the table shares the board's hearts, so the flush is settled by the highest heart anyone holds in hand. Hold 7♥ 6♥ and that card is your 7♥ — an opponent holding any heart above it takes the pot. That is why A♥ 7♥ above is the version you want: no heart outranks an ace.
The card that completes you can also complete someone else.

Frequently asked questions
What is a backdoor flush draw?
Three suited cards on the flop, needing both the turn and the river to cooperate. Two perfect cards in a row is far too rare to build a decision on, so treat it as a small bonus on top of a real hand — never as a reason to continue by itself.
