Royal Flush: Definition, Odds and Examples
A royal flush is the highest-ranking hand in traditional poker: the ace, king, queen, jack, and ten of a single suit, arranged in sequence. It is the top-end variant of a straight flush, and no other five-card combination can beat it in standard high-hand poker games such as Texas Hold'em, Omaha, and five-card draw. Because a royal flush requires five exact ranks in one suit, its composition never changes — only the suit that produces it varies from deal to deal.
What Makes a Hand a Royal Flush
Five criteria define a royal flush, and all five must hold at once. The hand needs the ten, jack, queen, king, and ace. Every card must belong to the same suit — spades, hearts, diamonds, or clubs. No wild cards or substitutions apply in standard rules. Any deviation, such as replacing the ten with a nine, produces a lower straight flush instead. For the broader mechanics of straight flushes below ace-high, the dedicated straight flush hand guide covers rank order and tie-break rules in full.
Why Suit Does Not Change the Ranking
Standard poker assigns no relative rank to suits. A royal flush in spades beats a full house exactly as a royal flush in clubs does — the suit is a qualifying condition, not a tiebreaker. This matters because players sometimes ask whether a certain suit carries more weight; it does not, in home games or in casino and tournament rules alike. The only requirement is internal consistency: all five cards must share one suit, whichever it happens to be.

Royal Flush Odds and Probability
In a standard 52-card deck, exactly four royal flushes exist — one for each suit. Drawing five specific cards from that deck produces 2,598,960 possible five-card combinations in total. Dividing four by that total gives royal flush odds of 1 in 649,740, or a probability of roughly 0.000154%. That figure applies to a single random five-card hand, such as a five-card draw deal before any cards are exchanged.
| Metric | Value |
|---|---|
| Possible royal flushes | 4 (one per suit) |
| Total 5-card combinations | 2,598,960 |
| Odds of a royal flush | 1 in 649,740 |
| Probability | ≈0.000154% |
Community-card games like Texas Hold'em change this math because players see seven cards total and choose the best five. That shifts the odds of a royal flush at showdown, and the full combinatorial breakdown across every hand type lives in the poker odds and probability guide rather than here.
Royal Flush Examples
A hand of ace, king, queen, jack, and ten of spades is a royal flush. So is the same rank sequence in hearts, diamonds, or clubs — four possible versions exist, and each ranks identically. In Texas Hold'em, a player might hold the jack and ten of hearts as hole cards, with the ace, king, and queen of hearts appearing on the board; the five community and hole cards combined form the royal flush. Because the hand's identity depends only on rank and suit match, no royal flush example outranks another.

Royal Flush in Poker Hand Rankings
Standard hand-ranking charts place the royal flush at the top, above a straight flush, four of a kind, and a full house. Some casino promotions and bad-beat jackpots single it out specifically because reaching it is so uncommon over a normal session. In most rule sets, if two players somehow reach a royal flush in the same hand, the pot splits evenly, since no suit outranks another and the five ranks are identical for both hands.
