What is a Royal Flush?
Royal Flush Poker Machine
The royal flush represents the strongest possible hand you can make in a game of poker. Royal flushes top all other hands in the poker hand rankings and are mathematically the rarest made hands that you can draw from a 52-card poker deck.
A royal flush consists of a ten-to-ace straight with all five cards of matching suits. A standard poker deck yields only four ways to make a royal flush, as the royal flush stands as the rarest of poker hands.
The hand occurs so infrequently, in fact, that you could play thousands of poker hands and never make a royal flush.

The Royal Flush Explained
Only four ways to make a royal flush exist in a standard 52-card poker deck. You can make an ace-to-ten straight in any of the four suits, (spades, hearts, diamonds, clubs), but all five cards must be the same suit for the hand to qualify as a royal flush.
The royal flush stands as the best possible straight flush you can make. A straight flush is made of five sequential cards that are all the same suit.
The royal flush sits on the top end of the spectrum of straight flushes you can make and sits atop all other hands in the poker hand rankings.
What Beats a Royal Flush?
No other made hand beats a royal flush in games that use the standard poker hand rankings. Royal flushes mark the best possible hand in games like Texas Hold’em, Pot-Limit Omaha Hi, Stud, Short Deck Hold’em, and many others.
In games with a hi-lo split, it’s possible for the best qualifying low hand to chop the pot with a royal flush. Games that use hi-lo split rules include Omaha Eight or Better, Stud Eight or Better, and a few other poker variants.
The royal flush is always an unbeatable high hand, however. In Texas Hold’em and Pot-Limit Omaha, it’s impossible for two players to use their hole cards to make a royal flush in the same hand.
Does a Five of a Kind Beat a Royal Flush?
Five of a kind doesn’t occur in games that use a standard 52-card deck. The Texas Hold’em and Pot-Limit Omaha games played in casinos around the world don’t use jokers or any kind of wild cards that would make five-of-a-kind possible.
Any poker game that includes five-of-a-kind as a possibility isn’t using a standard poker deck.
Do Four Aces Beat a Royal Flush?
Four aces make a very strong hand, but not strong enough to beat a royal flush. Four aces stand as the strongest possible four-of-a-kind you can possibly make, but all four-of-a-kind hands lose to the royal flush. All hands below four-of-a-kind in the poker hand rankings also lose to the royal flush.

Probability of a Royal Flush
A standard poker deck yields only one distinct way to draw a royal flush. Multiplying that by the four suits, there are four total possible ways to make a royal flush.
If you drew five random cards from a 52-card deck, you’d have an 0.000154% chance of making a royal flush. This probability can also be expressed as 649,739-to-1 odds against drawing a royal flush.
In Texas Hold’em, you’re tasked with making the best possible five-card hand out of seven total cards (two hole cards plus five community cards). In a game of Texas Hold’em, you have a 0.0032% chance of making a royal flush (30,939-to-1 odds against).
Examples of a Royal Flush
Examples of a royal flush include A♠K♠Q♠J♠T♠, A♥K♥Q♥J♥T♥, A♣K♣Q♣J♣T♣, and A♦K♦Q♦J♦T♦.
The standard versions of flushes and straights include many different ways to make those hands. The royal flush only gives you one distinct way to make the hand, however and four overall ways.
A royal flush can only be made as a ten-to-ace straight of all the same suit. Any suit can be used to make a royal flush, but only a ten-to-ace straight with all cards of the same suit qualifies as a royal flush.
The ins and outs of that most elusive of hands
By Henry Tamburin
I get many questions about a royal flush in video poker. That’s not too surprising since the royal flush is the premier hand that all video poker players dream (and hope) of getting. Here’s a sample of questions and my responses.
Q: I’ve been playing video poker several times a week for over a year. You keep saying that a royal flush occurs once in every 40,000 hands yet I still haven’t gotten a royal. What gives?
Firstly, I never wrote that you could expect one royal flush after playing 40,000 hands (or one cycle). What I wrote was, “On average, you will hit a royal flush once in every 40,000 hands.” The word “average” means a whole bunch of sets of 40,000 hands. In other words, in any given set of 40,000 hands, you could hit more than one royal flush or, heaven forbid, possibly no royals. In fact, you have a 36.8% chance that you won’t get a royal in one cycle (40,000 hands), and a 13.5% chance after two cycles (80,000 hands). Ouch! Therefore, the fact that you went over a year without a royal is statistically possible.
Q: How come every time I need one card for a royal flush, it never shows up, but that exact card that I needed always seems to show up on the very next hand?
That’s because you have “selective memory.” The computer program in the video poker machine that randomly selects the cards for each hand doesn’t use the information from previous hands to determine which cards it will deal. Every hand is a random deal regardless of what cards appeared (or didn’t appear) on the previous hand.
Q: Over three years, I hit seven royal flushes in the same casino and none in two other casinos that I play regularly. I’m beginning to believe those casinos somehow tighten their video poker machines so players can’t get a royal.
You will average one royal flush per roughly every 40,000 hands at any casino. Casinos can’t change the odds of hitting a royal flush. (What they can do is change the payout … some casinos will pay less than 4,000 coins for a royal flush; therefore, always check to be sure that the payout for a five-coin royal flush is 4000 coins.) The bottom line is as long as the pay schedule is the same for a particular video poker game, the odds of getting a royal flush will be the same no matter where the machine is located (assuming a random deal).
Q: I’ve been dealt many three- and four-card royal flushes lately. What are the odds of this happening?
Playing Jacks or Better, you’ll experience the thrill of being dealt a four-card royal flush once in every 2,777 hands (roughly once every four hours on average). Once in every 92 hands, on average, you’ll be dealt a three-card royal flush (about 7-8 per hour). This is what makes video poker exciting; namely, that you’ll have several opportunities to draw for a royal flush even if the odds are somewhat long (see next question).
Q: When you hold three cards to the royal flush, what is the chance of getting the two cards that you need on the draw for a royal flush?
You have a one in 1,081 chance of getting the two cards you need for the royal flush. The following table shows the chance of hitting the royal flush on the draw when you hold x cards to the royal flush.
:max_bytes(150000):strip_icc()/royalflush-56a73fdf3df78cf77293ac7a.jpg "What is a royal flush")
| RF Cards in Initial Five-Card Hand | Chance of Hitting the Royal Flush |
0 | 1 in 383,484 |
1 | 1 in 178,365 |
2 | 1 in 16,215 |
3 | 1 in 1,081 |
4 | 1 in 47 |
Q: If I’m dealt a three-card royal flush and a high pair in the same hand, why does the strategy say to hold the high pair when the royal flush pays so much more?
You need to analyze all the possible winning hands that you could get when you hold a three-card royal flush vs. when you hold a high pair in the same hand. These calculations have already been done for you. For example, suppose your initial hand contains 10-J-Q of diamonds along with a queen of clubs. The expected return (ER) for holding the pair of queens is 7.6827 vs. 7.4098 for holding the three-card royal flush (this is for 9/6 Jacks or Better). In dollars and cents, you’d earn 27 cents more on average for a max coin wager on a dollar denomination machine by holding the high pair vs. the three-card royal flush in this example.
Q: My wife plays Jacks or Better. The other day she was a dealt a hand that contained a four-card straight flush with a gap and a three-card royal flush. She held the three-card royal flush. Was that the correct play?
I’m sorry to say it wasn’t. The correct play was to hold the four-card straight flush—even with a gap—over the three-card royal flush. (Tip: If your wife had a strategy card with her, she would have made the right play.)
Q: What are the odds of being dealt a royal flush in the initial hand?
The odds are one in 649,740 hands. You might think that’s close to impossible but it could happen. (This happened to me once while I was showing my father-in-law how to play a Triple Line video poker game in a Las Vegas casino, resulting in a royal flush on each line. How’s that for luck?)
Q: How much does the royal flush contribute to the 99.54% return for 9/6 Jacks or Better?
The royal flush contributes 1.9807% toward the overall 99.64% return. The following table summarizes the contribution of each winning hand toward the overall 99.54% return (for 9/6 Jacks or Better). When you don’t hit the royal or straight flush, the best return you can expect, even playing perfectly, is about 97%.
| Hand | Contribution to Return |
| Royal Flush | 1.9807% |
| Straight Flush | 0.5465% |
| Four of a Kind | 5.9064% |
| Full House | 10.3610% |
| Flush | 6.6087% |
| Straight | 4.4917% |
| Three of a Kind | 22.3346% |
| Two Pair | 25.8558% |
| High Pair | 21.4585% |
| Total | 99.5439% |

Tamburin’s Tip of the Month
You are playing NSU Deuces Wild. How would you play these hands that don’t contain a deuce?
In the top hand, your best play is to hold the consecutive three-card straight flush 6-7-8 (2.77 ER) over the four card straight 5-6-7-8 (2.55 ER). In the bottom hand, because the three-card straight flush has a gap (2.47 ER) your best play is to hold the consecutive four-card straight 4-5-6-7. When you play NSU Deuces Wild and your initial hand doesn’t contain a deuce, you should hold a consecutive three-card straight flush (5-6-7 through 9-10-J) over a consecutive four-card straight (from 4-5-6-7 to 10-J-Q-K), but the latter over a three-card straight flush with one or two gaps.
