What is a Royal Flush?
The royal flush stands as the best hand in poker, at the top of the hand rankings. It includes the ten to ace, all in the same suit. This need for order and matching suit is what sets it apart.
In a deck of 52 cards, there are just four royal flushes – one per suit. It’s a mix of luck and skill, rare but greatly desired. For many poker players, landing a royal flush is a supreme goal. However, the chances are slim, which makes it even more special.
Historical Context of Poker Odds
The story of gambling and probability goes way back, long before poker became popular. The development of probability theory owes a lot to gambling and the desire to predict unlikely outcomes. Important figures like Fra Luca Paccioli and Girolamo Cardano were key to this process.
Fra Luca Paccioli was around at the same time as Leonardo da Vinci. He pioneered many math concepts. His “Summa de Arithmetica” dealt with chance problems, marking an early look into gambling and probability. His works laid the foundation for future probability studies.
Girolamo Cardano, a brilliant mind of the Italian Renaissance, expanded these ideas in “Liber de Ludo Aleae.” His work delved into game chance probabilities, pushing forward the development of probability theory. He mixed real gambling knowledge with math studies.
Though Paccioli and Cardano made vital starts, it was Blaise Pascal and Pierre de Fermat who truly defined the study. Their collaboration led to precise chance calculations, impacting various fields outside gambling.
Knowing this deep history helps us value poker odds more today. By acknowledging the groundwork laid by Fra Luca Paccioli and Girolamo Cardano, we gain insights into the math that shapes today’s gambling tactics and decisions.

Getting a royal flush in poker is quite rare. The odds vary a lot depending on the variant you’re playing. When looking at variant-specific poker odds, we see that every style of poker has different probabilities. For instance, Texas Hold’em players often have to do complex maths to work out the probability in Texas Hold’em of getting a royal flush.
In 5-card draw poker, the chance of landing a royal flush is extremely low. But in games like Texas Hold’em, where players use seven cards to make their best hand, the odds change a bit. This is because using seven cards gives players more combinations to try for the best five-card hand.

|---|---|---|
| 5-Card Draw | 5 | 1 in 649,740 |

| Omaha | 9 | 1 in 16,215 |
The table above shows that variant-specific poker odds change with the number of cards in play. With more cards available, the chance of getting a royal flush slightly increases. Yet, achieving it remains a significant and rare feat, no matter the poker variant.
