Cash game — high hand jackpots

Most common bonus

Many live poker rooms track the highest hand made during a session (typically an 8-hour period) and pay a jackpot. Royal flushes win every high-hand contest automatically. Online rooms sometimes offer daily or weekly high-hand bonuses as well.

Bad beat jackpots

Rare but large payouts

Bad beat jackpots typically require the losing hand to be four-of-a-kind or better. A royal flush losing to another royal flush is impossible in standard Hold'em. A straight flush losing to a royal flush at showdown can trigger most bad beat structures — and the payout is usually shared with the table.

Tournament promotions

Room-specific

Some tournament series offer prize bounties for making a royal flush during the event — typically a merchandise prize, free buy-in, or poker room credit. These promotions vary by property and are not universal. Check with the specific poker room for current promotion details.

What are the odds of getting a royal flush in poker?

In a 5-card poker hand, the probability is exactly 1 in 649,740 (0.000154%). There are 4 royal flushes in a standard 52-card deck — one per suit. In 7-card Texas Hold'em, the probability rises to 1 in 30,940 (0.0032%) because you see 7 cards instead of 5, creating C(7,5) = 21 different 5-card hand combinations. This 21× multiplier explains why royal flushes in Hold'em are dramatically more common than the pure 5-card figure suggests.

What is the probability of a royal flush in Texas Hold'em (7 cards)?

0.00323% per hand — approximately 1 in 30,940 hands dealt to you. Across a 9-handed full ring table, the probability that any player makes a royal flush is roughly 0.029% (1 in 3,440 hands per deal). A player who plays 100,000 hands in their career has approximately a 27% chance of having made at least one royal flush. The 1 in 30,940 figure is for individual hand dealt, not community-card appearances.

What hole cards give the best chance of making a royal flush?

Any two Broadway suited cards — specifically AKs, AQs, AJs, ATs, KQs, KJs, KTs, QJs, QTs, and JTs. All 10 combinations have identical probability of completing a royal flush by the river: approximately 0.020% (1 in 4,949). AKs requires Q-J-T of your suit on the board; JTs requires A-K-Q of your suit. The card ranks differ but the probability is structurally identical — 3 specific cards needed from the remaining 50.

How rare is 3-to-a-royal-flush on the flop?

With suited Broadway hole cards (e.g., K♠Q♠), you need one specific matching Broadway card on the flop to make a 3-to-a-royal. The probability depends on how many qualifying cards remain: with KsQs, you need one of Js, Ts, or As. Approximately 9 qualifying cards × (1/flop slot probability) across the 3-card flop gives roughly 0.90% for flopping at least 3-to-a-royal with any suited Broadway pair. The exact figure varies by specific holding.

How is royal flush probability calculated?

In 5-card poker: royal flushes = 4 (one per suit). Total 5-card hands = C(52,5) = 2,598,960. Probability = 4/2,598,960 = 0.000154%. For 7-card Hold'em, the calculation is more complex: count all 7-card combinations that contain a royal flush as a 5-card subset, then divide by C(52,7) = 133,784,560 total 7-card combinations. The result is 4,324 / 133,784,560 ≈ 0.00323%. The 4,324 figure counts all 7-card hands containing a royal flush (accounting for the 3 additional cards that can be anything).

Is a royal flush always the winning hand?

Always. A royal flush is the highest-ranking hand in standard poker — A-K-Q-J-T of one suit. No hand can beat it. The only 'tie' scenario would require two players holding royal flushes simultaneously, which in Texas Hold'em requires both players sharing all 5 board cards as their best hand. If two players both have the best 5-card hand being the board's royal flush, they chop the pot. Two players each contributing private cards to separate royal flushes cannot occur — the deck only contains one royal flush per suit.

What are the tournament implications of a royal flush?

In live tournaments, a royal flush rarely affects the outcome mechanically (it wins the pot like any other hand). However, many casinos offer high-hand jackpots or bad beat jackpots that may pay bonuses for royal flushes — though this is more common in cash games than tournaments. In cash games, a royal flush losing to a higher hand is impossible, but a royal flush that beats a straight flush (an extreme rarity) can trigger bad beat jackpots at many rooms. Some tournaments award prizes for making a royal flush during play as a promotional feature.
