A full house beats a flush every single time, in every standard poker game. It does not matter how high the flush runs or how modest the full house is — the category ranking decides the winner before individual card values ever come into play. Here is exactly why, and where players most often get this one wrong.
Confirming the ranking
A full house is three cards of one rank plus two cards of another rank — for example, three kings and two sevens. A flush is five cards of the same suit that are not in sequence. In the official order of poker hands, a full house sits above a flush, meaning even the weakest possible full house (threes over twos) beats the strongest possible flush (ace-high). For the complete ranking of all ten categories in order, see our poker hand rankings guide.
Why a full house outranks a flush
The ranking system in poker is built entirely on rarity: the harder a hand is to form, the higher it sits on the list. There are 3,744 possible full houses in a standard deck compared to 5,108 possible flushes. Because a full house requires two separate pairing events to line up — three of one rank and two of another, which is a tighter statistical target than simply matching suits — it is the rarer hand, and rarer always wins.
A real hand example
Picture a board of K-K-7-7-2 with two different suits showing. If you hold a king, you now have four of a kind — but if you hold a 7 with a matching kicker, or even just watch two players show K-7 and 7-2, full houses become live. Now imagine a different board where four cards of the same suit are showing, tempting anyone with one more card of that suit into thinking they hold the winner. If the full-house player is also at that table with two pair on the board plus a matching hole card, their full house wins outright, even though the flush looks flashier. This is exactly why reading the board for paired cards is just as important as watching for flush cards — a paired board is a full-house warning sign.
The mistake that costs the most chips
This is one of the more expensive misreads in poker because both hands often look strong and players get excited about a flush without checking whether the board is also paired. If you see three or more cards of the same suit and the board also has a pair on it, slow down — a full house is live for anyone holding the matching cards, and it beats your flush regardless of how high your flush runs. Committing a big stack with "just a flush" on a paired board without considering this is a classic and costly beginner mistake.
Comparing two full houses, or two flushes
When two players both make a full house, the hand with the higher three-of-a-kind wins first — three kings and two twos beats three queens and two aces, because the three-of-a-kind portion is compared first. When two players both make a flush, the highest card in the flush decides it, then the next-highest if needed.

Where a full house sits relative to everything else
A full house beats a flush, a straight, three of a kind, two pair, and one pair — but it loses to four of a kind and any straight flush. It is a genuinely premium hand, strong enough to stack off with in most situations, but not automatically the nuts. If four of a kind is also possible given the board pairing, our guide to four of a kind explains how that hand can still beat you even after you have made a full house.
