What Is Caribbean Stud Poker?
Caribbean Stud is a five card poker game played against the dealer rather than other players. You are not bluffing, not reading opponents, and not adjusting to the table. You are making one strategic decision per hand: whether to raise or fold. Everything else is fixed by the rules.
The house edge is around 5.22% with optimal strategy, higher than blackjack or baccarat, but lower than most proposition bets and well below the average slot machine. The game’s appeal is the progressive jackpot side bet, which gives players a shot at a large payout for hitting a royal flush, and the simple format that requires no poker experience to play.

Place your Ante, see your cards and the dealer’s up card, then decide to Raise or Fold. Strategy Mode shows the correct play after every deal.
How to Play Caribbean Stud Poker
- Place the Ante bet. Before any cards are dealt you place a mandatory Ante wager. This is the only required bet. Optionally, you can also place a $1 progressive jackpot side bet at this point.
- Receive five cards. You receive five cards face down. The dealer also receives five cards, with four face down and one face up. You can look at your hand but cannot share information with other players.
- Decide to raise or fold. This is the only decision in the game. After seeing your hand and the dealer’s up card, you either fold (lose the Ante) or raise (place a Raise bet exactly double the Ante). There is no other option.
- Dealer reveals and qualifies. The dealer turns over all four of their hidden cards. The dealer must have at least Ace-King to qualify. If the dealer does not qualify, you win even money on the Ante and the Raise pushes.
- Compare hands if dealer qualifies. If the dealer qualifies and beats your hand, you lose both the Ante and Raise. If you beat the dealer, the Ante pays 1:1 and the Raise pays according to the payout schedule below.
Raise Bet Payout Schedule
| Hand | Raise Payout |
|---|---|
| Royal Flush | 100:1 |
| Straight Flush | 50:1 |
| Four of a Kind | 20:1 |
| Full House | 7:1 |
| Flush | 5:1 |
| Straight | 4:1 |
| Three of a Kind | 3:1 |
| Two Pair | 2:1 |
| One Pair or Ace-King | 1:1 |
The Ante always pays 1:1 on a win. The bonus payouts above apply only to the Raise bet when you win and the dealer qualifies. If the dealer does not qualify, only the Ante pays — the Raise pushes regardless of how strong your hand is.
The Dealer Qualification Rule
This is the most important mechanic to understand in Caribbean Stud Poker. The dealer must hold Ace-King or better to qualify. If the dealer’s hand is weaker than Ace-King, say, Queen-Jack high, the dealer does not qualify and the hand ends immediately. You collect 1:1 on your Ante, and your Raise bet is returned as a push.
This rule cuts both ways. It protects you when the dealer is weak, but it also costs you bonus payouts when you have a strong hand and the dealer fails to qualify. A royal flush against a non qualifying dealer pays the same as a pair of twos, just 1:1 on the Ante. This is the single most frustrating feature of the game, and it is also unavoidable.
The dealer qualifies roughly 56% of the time in a standard game.
Caribbean Stud Poker Strategy
Optimal strategy reduces the house edge to approximately 5.22%. The decision tree is simple, there are only two choices, but the correct threshold for raising versus folding is specific.
Always Raise
Raise with any hand that contains a pair or better. No exceptions. These hands have positive expected value when raised, regardless of the dealer’s up card.
Always Fold
Fold all hands weaker than Ace-King high. You lose only the Ante, which is better than losing both the Ante and the Raise on a hand that is unlikely to win.
The Ace-King Decision (The Critical Zone)
Ace-King high hands require a more nuanced decision. The optimal strategy for Ace-King hands depends on your remaining three cards and the dealer’s up card.
Raise with Ace-King if any of these are true:
- The dealer’s up card matches one of your other three cards (reduces the chance the dealer has a pair)
- You hold Ace-King-Queen or Ace-King-Jack (your high kickers improve your chance of winning an Ace-King vs Ace-King comparison)
- The dealer’s up card is 2 through Queen and matches your fourth or fifth card
Fold Ace-King otherwise. A bare Ace-King with weak kickers against a dealer up card that does not match your hand is a marginal fold. Raising it costs you expected value over the long run.
The Progressive Jackpot Side Bet
The $1 progressive side bet is a separate wager on the strength of your own hand, independent of the dealer. It pays out on a flush or better regardless of whether the dealer qualifies or what the dealer holds.
| Hand | Progressive Payout |
|---|---|
| Royal Flush | 100% of jackpot |
| Straight Flush | 10% of jackpot |
| Four of a Kind | $500 (fixed) |
| Full House | $100 (fixed) |
| Flush | $50 (fixed) |
The house edge on the progressive side bet is typically between 26% and 40%, depending on the current jackpot size. The bet only approaches positive expected value when the jackpot is extremely large, in the range of $263,000 or more for a standard 52-card game. At typical jackpot levels the side bet is a poor wager. Place it for entertainment if you want the lottery-style shot at the jackpot, but do not expect it to improve your results.
House Edge Summary
| Bet | House Edge | Notes |
|---|---|---|
| Ante + Raise (optimal strategy) | 5.22% | Applies to total action (Ante + Raise combined) |
| Ante only (always fold raises) | ~100% | You lose the Ante every non-qualifying hand |
| Progressive side bet | 26-40% | Varies with jackpot size |

Caribbean Stud Glossary
Ante The mandatory bet placed before cards are dealt. Pays 1:1 when you win and the dealer qualifies, and 1:1 when the dealer does not qualify.
Raise The optional bet placed after seeing your cards, equal to exactly twice the Ante. You either raise or fold, no other sizing is allowed.
Qualify The dealer qualifies by holding Ace-King high or better. If the dealer does not qualify, the Raise pushes regardless of your hand strength.
Progressive Side Bet An optional $1 bet placed before the deal that pays on a flush or better in your hand, independent of the dealer’s hand or whether the dealer qualifies.
Ace-King The minimum qualifying hand for the dealer. Also the threshold hand in your own decision, the raise/fold decision with Ace-King high is the most strategically complex situation in the game.
Push The Raise bet is returned without winning or losing. This occurs whenever the dealer does not qualify.
Fold Surrender the hand and forfeit the Ante. The correct decision with hands weaker than the optimal raise threshold.
Frequently Asked Questions
What is the best strategy in Caribbean Stud Poker?
Always raise with a pair or better. Always fold with less than Ace-King. With Ace-King, raise if the dealer’s up card matches one of your other cards, or if you hold Ace-King-Queen or Ace-King-Jack. Fold Ace-King with weak kickers otherwise. This strategy produces a house edge of approximately 5.22%.
What happens if the dealer does not qualify?
If the dealer holds less than Ace-King high, the dealer does not qualify. You win even money on your Ante and your Raise bet is returned as a push, regardless of the strength of your hand. This means a royal flush against a non-qualifying dealer pays the same as any other winning hand: 1:1 on the Ante only.
Should I always place the progressive side bet?
No. The progressive side bet carries a house edge of 26% to 40% at typical jackpot levels. It only becomes a reasonable bet when the jackpot exceeds approximately $263,000, which is rare. Place it if you want the entertainment value of chasing a large payout, but understand it is a costly bet in expected value terms.
Can I look at other players’ cards?
No. Caribbean Stud Poker rules prohibit sharing card information between players. You can see only your own hand and the dealer’s one exposed card. The no collusion rule is strictly enforced because knowing other players’ cards would significantly affect the correct raise/fold decision.
What is the house edge compared to other table games?
Caribbean Stud’s 5.22% house edge is higher than blackjack (0.5%), baccarat Banker bet (1.06%), and European Roulette (2.70%). It is comparable to American Roulette (5.26%) and lower than most proposition bets and slot machines. If minimizing house edge is the priority, blackjack or baccarat are better choices. Caribbean Stud’s appeal is the progressive jackpot and the simple format.
Is Caribbean Stud the same as regular poker?
No. Caribbean Stud uses standard poker hand rankings, but the game mechanics are entirely different. You play against the dealer, not other players. There is no bluffing, no betting rounds, and no ability to raise the stakes based on hand strength. The only decision is whether to raise the fixed Raise amount or fold. It is a casino table game that borrows poker’s hand hierarchy, not a poker game.
