Spice Island Poker

Cryptologic is one of the online casino software companies that offers Caribbean Poker. You might not notice this when first playing at a Cryptologic casino, because they call their version of Caribbean Stud, Spice Island Poker. But if you start playing it, you will realize soon enough it's exactly the same game as Caribbean Stud Poker. In this section we will give you some more information about Spice Island Poker, especially how it compares to "standard" Caribbean Stud Poker.

Spice Island Poker pay table (call bet)

Hand Cryptologic pay table Standard pay table
1 Pair or Less 1 to 1 1 to 1
2 Pair 2 to 1 2 to 1
3 of a Kind 3 to 1 3 to 1
Straight 4 to 1 4 to 1
Flush 5 to 1 5 to 1
Full House 7 to 1 7 to 1
4 of a Kind 20 to 1 20 to 1
Straight Flush 50 to 1 50 to 1
Royal Flush 200 to 1 100 to 1

As you can see in the table above, Cryptologic uses a standard pay table, with the exception of the raised pay out on the Royal Flush, which has been increased from 100 to 1 to 200 to 1. Of course, this results in a lower house edge than the 5.22% that is standard for Caribbean Stud Poker. The house edge for Spice Island Poker is 5.207489892%, which is slightly lower than the standard 5.22%.

Spice Island Poker pay table (side bet)

Hand Cryptologic pay table Standard pay table
Royal Flush 100% of the progressive jackpot 100% of the progressive jackpot
Straight Flush 10% of the progressive jackpot 10% of the progressive jackpot
4 of a Kind $500 $100
Full House $100 $75
Flush $50 $50

Cryptologic offers a rather generous pay table on the progressive side bet, raising the pay outs on two hands: the four of a kind and the full house. This doesn't change the fact that the side bet has a high house edge, it only means that the jackpot size has to be less than standard, to overcome the house edge on Spice Island Poker's side bet. The jackpot reset value will be dependent on which casino you play. At the time of writing this, the Sands had a reset value of $100,000 while William Hill was at $50,000.

Minimum Spice Island Poker Jackpot

So how high needs the jackpot to be in Spice Island Poker to make the side bet worthwhile (that is give it a zero house edge). Let's do some math:

Hand P[Hand]* Returns P[Hand] x Returns
Royal Flush 0.000001539 Jackpot Jackpot x 0.000001539
Straight Flush 0.000013852 Jackpot x 0.10 Jackpot x 0.0000013852
4 of a Kind 0.000240096 $500 0.120048
Full House 0.001440576 $100 0.14440576
Flush 0.001965402 $50 0.0982701
      $1

Solving the following equation:

$1 = 0.0982701 + 0.14440576 + 0.120048 + Jackpot x (0.0000013852 + 0.000001539)

Gives a minimum Jackpot value of $217,931.81
