Caribbean Stud Poker is a five-card casino poker variant where players compete against the house rather than each other. Like Three Card Poker, Caribbean Stud features an Ante bet (compete vs dealer) and a side bet (the progressive jackpot bet). Caribbean Stud has a higher house edge than most poker variants — 5.22% on the Ante with optimal strategy — driven by the 5-to-1 call bet structure (the raise bet must equal 2× the Ante, creating larger exposure on losing hands). The progressive jackpot side bet adds a lottery element: a Royal Flush typically pays 100% of the jackpot, a Straight Flush pays 10% of the jackpot. Progressive jackpots at Caribbean Stud can reach six and seven figures at some operators.
Caribbean Stud is popular for its simplicity (one strategy rule covers most hands) and the excitement of the progressive jackpot. It's not an EV-optimal casino game — the 5.22% house edge is high compared to blackjack (0.5%), baccarat (1.06%), and Three Card Poker (2.01%). This guide covers Caribbean Stud mechanics, the complete strategy, house edge breakdown, and the progressive jackpot bet analysis.

Setup: Caribbean Stud uses a standard 52-card deck. The player and dealer each receive five cards. One dealer card is dealt face-up; four are face-down. The player's five cards are all dealt face-down (seen only by the player). Optional: before cards are dealt, the player may also place a progressive jackpot side bet (typically £1 fixed amount, separate from the Ante).
Round sequence: (1) Player places Ante bet. (2) Cards dealt: 5 to player (face-down), 5 to dealer (4 face-down, 1 face-up). (3) Player views their 5 cards and the dealer's 1 visible card. Decision: FOLD (forfeit Ante, lose) or RAISE (place raise bet = 2× Ante). (4) Dealer reveals all 5 cards. Dealer qualifies if holding Ace-King or better (A-K high or better, any pair or better). If dealer doesn't qualify: Ante pays 1:1, Raise bet pushes (returned regardless of player hand strength). If dealer qualifies and player beats dealer: Ante pays 1:1, Raise bet pays by paytable (1:1 Pair through Flush, 2:1 Full House, 3:1 Four of a Kind, 10:1 Straight Flush, 20:1 Royal Flush at some operators — paytable varies). If dealer qualifies and dealer beats player: Ante and Raise both lost. Tie: both push (returned).
Progressive jackpot side bet: Placed before the hand, typically £1. Pays based on the player's hand regardless of dealer's hand. Standard progressive paytable: Royal Flush = 100% of jackpot (or fixed large amount), Straight Flush = 10% of jackpot (or fixed), Four of a Kind = £100 fixed, Full House = £75 fixed, Flush = £50 fixed (paytables vary by operator). The progressive jackpot side bet has a very high house edge (typically 26–54% depending on jackpot size and paytable) — it's a high-variance lottery bet, not an EV play. Only positive EV when the jackpot reaches very large specific thresholds (depends on paytable and jackpot size — calculate jackpot break-even size using expected value formula).
Caribbean Stud Optimal Strategy
Always raise: Any pair or better. No exceptions — two pair, three of a kind, straight, flush, full house, four of a kind, straight flush, royal flush: always raise.
Always fold: Less than Ace-King (e.g., K-Q-J-x-x, Q-high, J-high etc.). Any hand not containing at least A-K high should be folded.
Ace-King hands (the key decision): Raise Ace-King if ANY of the following apply: (a) the dealer's face-up card matches any of your 2nd through 5th cards (you have a blocker to dealer pairing); (b) your hand contains a Queen or Jack AND the dealer's up-card is lower than your highest non-A-K card; (c) your A-K includes a Queen or Jack as the third highest card. Otherwise: fold Ace-King without these conditions. The simplified version (slightly suboptimal but effective): always raise with A-K-Q or better; always fold with A-K-J or worse unless dealer shows a matching card to one of your non-A-K cards.
House edge: With the complete optimal A-K decision tree: 5.22%. With the simplified "always raise A-K" rule: approximately 5.50%. With the simplified "always fold A-K" rule: approximately 5.70%. The 5.22% house edge is the theoretical best achievable with perfect play. Caribbean Stud's high house edge is structurally driven by the 2× raise requirement — the raise must be 2× the Ante, so losing a raised hand costs 3× the Ante (Ante + Raise) while winning a pair hand gains only 2× (Ante + 1:1 Raise). This asymmetry creates the high house edge.
For comparison, Three Card Poker has a 2.01% house edge with optimal Q-6-4 strategy. Blackjack achieves 0.5% house edge with full basic strategy. Caribbean Stud is best played for entertainment — the progressive jackpot adds excitement for minimal side-bet investment.

The progressive jackpot side bet has an even higher house edge (typically 26–54%) unless the jackpot is exceptionally large. Caribbean Stud is a casino game for entertainment and jackpot excitement — not an EV-optimal game for high-volume play.
