Calculating the Probability of Getting Royal Flush

The probability calculation can be explained for the different styles-

To get a straight flush that is ace to ten, it is necessary to start the hand with two suited cards between ten and ace. Either way in this, it is still necessary to get precise 3 cards to make a Royal Flush Hand. This still reduces the chances to minimal. However, drawing from a deck of 52 cards, gives it nearly no probability as there are precisely 19,600 varied hands that a player can get. The odds of getting a Royal Flush Hand – exactly 1 in 19,600.

1/19,600 = 0.00005
This amounts to only 0.00005% probability, making it almost impossible for a player to get.

Since the chance of getting a Royal Flush is so low in a Pre Flop, or nearly impossible, another method gives it a slightly higher chance. It is called Straight Draw. In this method, only two possible cards falling ensure a Royal Flush Hand.

In this case, the chance increases to 141 times in 19000 possible draws. Thus, giving it a chance of 0.007 percent. However, this percentage is extremely low, and not just that, chances of this occurring are less than 1 percent of the time.

Making the Royal Flush post-flop creates a bigger probability and provides a realistic window for creating a Royal Flush Hand. The different methods of post-flop produce a number figure around 2.2 percent and 4.4 percent, respectively.

Royal Flush Poker Ranking FAQ

Royal Flush can consist of only four possible combinations, that is, straight with ace high of the four suits. No other combination can form Royal Flush Hand. Hence in a classic deck, it cannot be beaten. “Four of a kind”, that is four same ranked cards of four different suits, come second to it.

Royal Flush can only be beaten in a poker deck with wild cards. Wild cards include the likes of a joker. In that case, the "five of a kind" becomes the highest hand. The "five of a kind" can hence beat a Royal Flush. But it is not a possibility in a standard Poker Deck.

A RoyalFlush can be of any suit. It is only a set of four possible combinations, one from each suit. A general question and misconception often arise as to what suit ranks above what suit in poker.

Unlike many other card games, Poker does not alphabetically or systematically rank suits. This means no suit holds special value because of colour. All suits in Poker hold the same value, and other factors like ranking, hand, doubles, triples, straights and flushes decide the highest hand in Poker.

When it comes to the Royal Flush, all four suits rank equally. Since the specific combination of cards is fixed, the only thing separating different Royal Flushes are the suits. However, all the suits are equal to each other and two royal flushes cannot be above or below each other. Also, as it is so rare to get a Royal Flush Ranking, there is almost no chance of two players getting a Royal Flush. In any case, hypothetically if two players do manage to get Royal Flushes, there is no tie-breaker to decide it and the pot is split between the two.

The specific combination – the Ace, King, Queen, Jack and Ten, which are the five highest cards of their respective suits, ranks the highest in a standard Poker game. This combination of the Royal Flush Hand is unbeatable in a 52 card standard deck.

In a poker deck with wildcards, like jokers or with other house rules, the Royal Flush ranks second highest. The "five of a kind" ranks the highest in a wildcard game. Five of a kind includes four same cards of different suits and one joker wild card. Rankings within the "five of a kind" hand vary with the ace being the highest-ranked “five of a kind” card and two being the lowest. However, all of them rank above Royal Flush.

A common misconception is that Four Aces can beat a Royal Flush. This is partially due to the fact that many rulebooks, especially the ones available online state that Royal Flush is the second-highest hand. This is only true for a non-standard poker deck with wild cards, in which case "Five of a kind" is the highest card. Four Aces, though high in value and probably a sure win in almost all cases, cannot beat a Royal Flush Hand. Four aces is still a "Four of a kind" hand and it ranks lower than Royal Flush. Hence, in a standard deck with 52 cards, as there cannot be “five of a kind”, Royal Flush remains the highest. “Four of a kind” comes right after it, and "four aces" is literally the second highest hand in the game, sitting right after Royal Flush and above all other "Four of a kind"s.

A large part of this game is luck. Winning in poker is nearly impossible without being lucky. However, there are methods to boost your chances by knowing the tricks and tips, and with experience at reading the games. A good poker player can turn their luck around and command a game even with an unlucky hand of cards. Knowing how to boost your chances for a Royal Flush to work, ensures a greater probability of winning the game in hand.
The chances of getting a Royal Flush Hand are very less, however, a Royal Flush Poker strategy goes a long way. Knowing when to hold the cards and when to fold the cards is what sets good players apart from just lucky players. Expert players constantly calculate probabilities and execute their strategies accordingly.
