Royal Flush vs Full House: Which Wins?

A royal flush always beats a full house. The royal flush is the single highest hand in poker, sitting at #1 on the ten-hand ladder, while a full house ranks #4. It doesn’t matter how big the full house is — aces full of kings, the strongest boat possible, still loses to any royal flush. This matchup is one of the most lopsided in the game, and it’s never close.

Where each hand ranks

Poker’s hand order, best to worst, puts these two far apart:

Rank	Hand	Example
#1	Royal flush	A♠ K♠ Q♠ J♠ 10♠
#2	Straight flush	9♥ 8♥ 7♥ 6♥ 5♥
#3	Four of a kind	Q Q Q Q 4
#4	Full house	K K K 7 7

The royal flush is a full four steps above the full house. Because it’s the top hand, it also beats the straight flush and four of a kind that sit between them — so a full house never has a path to winning. See the definitive top of the ladder in royal flush explained.

Why the royal wins: rarity

Poker ranks hands by how hard they are to make — the rarer the hand, the higher it ranks. The gap here is enormous:

• Royal flush: just 4 ways to make it (one per suit) out of 2,598,960 five-card hands.
• Full house: 3,744 ways — 13 choices for the trip rank, times 4 ways to pick 3 of those 4 cards, times 12 remaining ranks for the pair, times 6 ways to pick 2 of those 4 cards: 13 x 4 x 12 x 6 = 3,744.

The full house is about 936 times more common than the royal flush. That rarity gap is the entire reason the royal outranks it — and by such a wide margin.

A worked cooler example

Community-card board: A♠ K♠ Q♠ 7♦ 7♣.

• Player A holds K♦ K♥ → best five: K♦ K♥ K♠ 7♦ 7♣ = kings full of sevens, a monster full house.
• Player B holds J♠ 10♠ → best five: A♠ K♠ Q♠ J♠ 10♠ = royal flush in spades.

Player A’s boat would crush almost anything, but Player B has completed the royal. The royal flush is #1 and the full house is #4, so Player B wins the entire pot. This is the ultimate cooler — the strongest hand many players ever make, only to run into the one hand that can’t be beaten.

”Does a spade flush beat a full house?”

This is a common point of confusion, so it’s worth separating two different hands:

• A plain flush (five cards of one suit that are not in sequence, e.g. A♠ J♠ 8♠ 5♠ 2♠) ranks #5 — below a full house. A plain spade flush loses to a full house.
• A royal flush is A♠ K♠ Q♠ J♠ 10♠ — five sequential spades. That’s a straight flush, the #1 hand, and it beats every full house.

So the suit doesn’t change anything: what matters is whether the flush is also a straight. A plain flush loses to a full house; a royal flush beats it. For the full picture of what tops a boat, see what beats a full house.

How ties work (they don’t help the full house)

Some players wonder whether a big enough full house or a tiebreak rule can rescue the boat. It can’t:

• Full house vs. full house is decided by the trips first, then the pair — A-A-A-K-K beats K-K-K-A-A. But that only settles which full house is best; it has no bearing on the royal, which outranks all of them.
• Royal flush vs. royal flush can only tie. Because there’s exactly one royal per suit and all suits are equal in poker, two royals split the pot. That’s the only “tie” a royal is ever part of — and a full house is never in that conversation.

There is no kicker, no suit ranking, and no board texture that lets a full house climb above a royal flush. The hierarchy is absolute.

What each hand beats

The royal flush beats every hand in poker — it’s the literal nuts wherever it appears. A full house beats a flush, straight, three of a kind, and everything below, but loses to four of a kind, straight flushes, and the royal. A strong hand, just not against the top of the chart.

Quick summary

• A royal flush always beats a full house — #1 versus #4, no exceptions.
• Even aces full, the best possible full house, loses to any royal.
• The royal wins on rarity: 4 ways to make it versus 3,744 for a full house.
• A plain flush is different — it ranks below a full house; only a straight flush or royal beats a boat.

Bottom line

Royal flush versus full house isn’t a real contest: the royal is the best hand in poker and the full house sits four rungs down. Any royal beats any full house, every time.
