Definition and Meaning
The pinnacle of poker hands, the Royal Flush represents the dream for every player. Its power derives from the combination of its two central components:
- The highest Straight in poker (10 through Ace).
- The same suit.
While Straights and Flushes on their own rank highly, together they create an unstoppable hand.
Definition in short: A Royal Flush is the highest ranking poker hand, comprised of the Ace, King, Queen, Jack, and 10 all of the same suit.
Examples of a Royal Flush
Below we will show you an image of what a Royal Flush looks like:
Logically, due to there being four different suits in a standard deck of cards, there are only four different ways of completing this hand.
- Hearts: A♥ K♥ Q♥ J♥ 10♥
- Spades: A♠ K♠ Q♠ J♠ 10♠
- Diamonds: A♦ K♦ Q♦ J♦ 10♦
- Clubs: A♣ K♣ Q♣ J♣ 10♣
Probabilities
Assuming the most popular variation, Texas Hold’em Poker, the data is as follows:
| Odds | Probability |
|---|---|
| 1 in 30,940 | 0.00323% |
The odds of making a Royal Flush in Texas Hold’em are approximately 1 in 30,940. This means that, on average, it will occur once every 30,940 hands.
So while this combination is extremely rare, it is still possible to hit it by getting very lucky. You are statistically about as likely to flip Heads 15 times in a row as you are to make a Royal Flush!
Note: many sources mention 1 in 649,740 as the odds for a Royal Flush.1 It is important to point out that this number only applies to being dealt a Royal in a single 5-card hand. In Texas Hold’em, players can use seven cards to form their best 5-card hand. Thus, the odds improve to 1 in 30,940.
Odds for Other Poker Games
The Royal Flush always contains the same five cards (A-K-Q-J-10 of the same suit). However, the probability of completing it changes depending on the poker variant being played.
The main reason the odds change is the number of cards available to create your final five-card hand. Some games allow players to use seven cards, others deal exactly five. Draw-based formats like video poker introduce additional mathematical variations.
The two tables below rank popular poker variants by Royal Flush probability, from highest chance to lowest in terms of chance:
Table 1: Traditional Poker Variants (Highest to Lowest Probability)
| Poker Variant | Structure | Odds | Probability |
|---|---|---|---|
| Omaha | 4 hole + 5 community | ~1 in 13,194 | ~0.0076% |
| Seven Card Stud | 7 cards total | 1 in 30,940 | 0.00323% |
| Five Card Draw | 5 cards | 1 in 649,740 | 0.000154% |
Table 2: Casino Poker Variants (Highest to Lowest Probability)
| Casino Poker Game | Structure | Odds | Probability |
|---|---|---|---|
| Ultimate Texas Hold’em | 2 hole + 5 community | 1 in 30,940 | 0.00323% |
| Mississippi Stud | 2 hole + 3 community | 1 in 30,940 | 0.00323% |
| Let It Ride | 3 hole + 2 community | 1 in 30,940 | 0.00323% |
| Pai Gow Poker | 7 cards (split into high/low hands) | ~1 in 30,940* | ~0.00323% |
| Video Poker (Jacks or Better, optimal play) | 5 cards + draw | ~1 in 40,000 | ~0.0025% |
| Caribbean Stud | 5 cards | 1 in 649,740 | 0.000154% |
*Pai Gow Poker often uses a joker, which can slightly affect probabilities depending on house rules.
Why the Odds Differ
- 7-card formats increase the number of possible 5-card combinations, improving the probability compared to fixed 5-card games.
- Omaha games slightly increase the chance further because you get four hole cards, creating more possible suited combinations.
- 5-card games offer significantly lower odds as there are no additional community cards to improve your hand.
- Video Poker sits between these formats. While you are initially dealt just five cards, the draw mechanic allows you to discard and replace cards strategically. This significantly improves your long-term chances of completing a Royal Flush compared to fixed 5-card table games.
Royal Flush Strategy
The best strategy for capitalizing on a Royal Straight Flush opportunity involves maximizing value before and after hitting the hand.
- When drawing to a Royal Flush, bet aggressively to build the pot, while avoiding exposing the draw. Make reads on opponents to determine how much they are willing to call.
- Once you hit it, continue raising while disguising your holding. Since this hand almost never materializes, opponents will likely call large bets, believing you to be bluffing. Milk every street to swell the pot as much as possible.
- Finally, on the extremely rare occasion of facing a possible tie, avoid overplaying the hand before the river, as that may tip off any opponents also drawing to a Royal Flush. Even when another player hits one too, splitting the pot is still a success when holding poker’s best hand.
Just remember, the goal in poker is not to hit a Royal Flush, but to walk away with more chips than you joined to the table with!

My question is how wild cards can make up a Royal and Straight Flush. As:
Can the Ace be the wild? Do the wild cards need to be the same (as all spades/hearts)
Paul Dunlop
Playing with wild cards is mainly a house rule thing and is different everywhere. However, when playing with so-called “Bugs”, the following is common:
– Typically a Joker is used.
– It can fill in a missing rank to complete a Straight or a Flush.
– In other cases, it acts as an Ace.
The wilds do not need to be of the same suit.
John Paul Bacon
Hello. When there are Wild-Cards they can be any card that’s in the deck. Say your playing 5 card draw with wild cards , then the best hand would be 5 aces. You will need at least one natural ace to make the wildcards aces. When playing with wildcards any 5 of a kind beats everything Iower then a 5-of-a-kind which is every hand from high card to royal straight flush. The best 5 of a kind are 5 aces are the highest of the 5 of a kinds. So 5 jacks would beat all 5 of a kinds below the jacks 2’s through 10’s but 5 queens and higher will beat the 5 jacks.
