Caribbean Stud Poker 101 – Rules, Strategy & House Edge
A fast, one-on-one poker game against the dealer, usually paired with a progressive jackpot side bet. This guide covers the raise/fold decision, why the progressive bet is nearly always a bad deal, and what house edge to expect.

Written by 1. How Caribbean Stud Poker Works
You play one-on-one against the dealer, not against other players. Everyone at the table plays against the same dealer hand, but your result depends only on your own cards versus the dealer's.
The core decision
After seeing your 5 cards and one exposed dealer card, you have exactly one decision: raise (bet double your ante) or fold (forfeit your ante). There's no drawing or discarding — it's a single yes/no call.
2. Raise/Fold Strategy
The fully optimal strategy is genuinely complex — it depends on your exact five cards and which card the dealer is showing. Most players use one of two simplified versions instead:
Simple strategy (recommended for most players)
Always raise with a pair or better. Fold anything weaker than Ace-King. For Ace-King hands specifically, raise only if your kicker matches the dealer's exposed card — otherwise fold.
An even simpler rule of thumb — raise with Ace-King-Jack-8-3 or better, fold anything weaker — comes within about 0.1% of the fully optimal strategy's house edge. That's a small enough gap that most players use this version rather than memorizing the complete chart.
3. House Edge Summary
| Bet | Typical House Edge | Notes |
|---|---|---|
| Ante/Raise (optimal strategy) | ~5.22% of ante / ~2.56% of total action | The "element of risk" figure (2.56%) is the more useful number for comparing against other games. |
| Progressive side bet | Commonly 20%+ | Directly tied to the current jackpot size — can be dramatically higher when the jackpot is small. |
*The Ante/Raise edge assumes correct strategy; playing "always raise" or "never raise" produces a noticeably worse result. See House Edge by Game for how this compares to other table games.
4. Why the Progressive Bet Is Usually a Trap
The progressive side bet pays out based purely on your own hand's poker value (a flush or better), independent of the dealer, with a shot at the full jackpot for a royal flush.
- Its house edge moves with the jackpot size — the smaller the jackpot, the worse the bet.
- Even at a large jackpot, the edge is still typically far higher than the main Ante/Raise bet.
- Royal flushes are extremely rare, so most players who bet the progressive never see a meaningful return from it.
Most strategy resources recommend treating it as pure entertainment money at most — small stakes, no expectation of long-term value.
5. Bankroll Planning for Caribbean Stud
- Decide your total session bankroll before sitting down.
- Remember your effective bet size is higher than your Ante alone — you'll be raising (2x) on a majority of hands, so budget accordingly.
- If you play the progressive, treat it as a small separate entertainment budget, not part of your core bankroll math.
6. Keeping It in Perspective
The progressive jackpot display is designed to be tempting. Know the math behind it before you chase it.
- Treat every session as paid entertainment, not income.
- Stick to your raise/fold strategy consistently — don't improvise based on a "feeling."
- Take breaks and walk away at your limits.
