Does a Full House Beat a Flush?

By Published Last updated

Yes — a full house beats a flush, in every standard form of poker. This is the matchup players get backwards most often, because a flush looks cleaner than "three of one thing plus two of another." But the rankings run on rarity, and the full house is the rarer hand. Here's the quick answer, the math, and the one variant where it genuinely flips.

Full House vs Flush: The Quick Answer

HandExampleResult
Full house — three of a kind + a pair3♠ 3♥ 3♦ 2♣ 2♦Wins
Flush — five cards, one suitA♠ K♠ J♠ 8♠ 4♠Loses — even at its strongest

Note the example on purpose: threes full of twos — the smallest full house in the deck — beats an ace-high flush, the best plain flush there is. Hand categories are compared first; the cards inside only break ties within the same category.

Why the Full House Ranks Higher: The Math

Out of the 2,598,960 possible five-card hands:

HandWays to make itOdds of being dealt it
Flush5,108≈ 0.20% (1 in 509)
Full house3,744≈ 0.14% (1 in 694)

Locking five cards into one suit is hard; needing an exact pattern of ranks — a trio plus a pair — is harder still. In seven-card Texas Hold'em the gap holds too: flushes arrive in about 3.0% of hands, full houses about 2.6%.

The Showdown That Stings

This matchup decides huge pots in Hold'em, because the same board that completes a flush often pairs up. Board: K♥ 9♥ 9♦ 4♥ 2♣:

This is why experienced players tap the brakes with a flush on a paired board — the pair is exactly the ingredient a full house needs. (Flush still comfortably beats a straight and three of a kind, though — see flush vs straight and flush vs 3 of a kind.)

The One Real Exception: Short Deck

In Short Deck (6+) Hold'em — 36 cards, with the 2s through 5s removed — flushes become rarer than full houses, and most rooms flip the order: flush beats full house. It's the only widely played variant where this page's answer reverses. In everything played with a 52-card deck, the full house wins.

In Boosted Poker the ladder stays standard, but per-hand table modifiers make this exact collision more common — Four-Card Flush completes flushes with just four suited cards, and boards still pair as usual, so flush-into-full-house showdowns come up constantly. The full house wins every time.

Frequently Asked Questions

Does a full house beat a flush?

Yes — in every standard variant. The smallest full house beats the biggest plain flush.

Is a full house better than a flush?

Yes, by one rank: flush is #5 on the ladder, full house is #4. It's rarer (≈1 in 694 five-card deals vs ≈1 in 509), and rarity sets the rankings.

Full house vs flush — who wins?

The full house, regardless of the flush's high card. Only a straight flush — a different, stronger category — beats a full house while being "all one suit."

Does a flush ever beat a full house?

Only in Short Deck (6+) Hold'em, where the stripped deck makes flushes rarer and most rooms rank them above full houses.

How are two full houses compared?

Trips first, then the pair: kings full of twos beats queens full of aces. Identical hands split the pot.
