Caribbean Stud Jackpot EV Calculator

In Caribbean Stud Poker, there is almost always a flashing Progressive Jackpot meter. To win it (or 10% of it), you must place a $1 side bet.

Most of the time, this $1 bet has a terrible house edge (>25%). However, as the jackpot grows, the edge shrinks. Eventually, it becomes Positive EV. This calculator tells you if the current jackpot is large enough to play.

The Break-Even Rule

For a standard paytable (100% Royal, 10% Straight Flush), the Break-Even point is usually around $200,000 to $250,000.

  • Below Break-Even: Do not play the side bet.
  • Above Break-Even: The bet is +EV. You should play it every hand, as your average return is greater than $1.
