Black Jack Bonus Poker

Black Jack Bonus Poker is a variation of Bonus Poker which has extra payouts for Four of a Kind hands where the kicker card is a Black Jack (the Jack of Clubs or the Jack of Spades). Because this game is suit-specific, the simplified deck is not as simple as it is for most games. Instead of eliminating 95% of the processing time, only 87% can be eliminated. If you run a strategy guide or analyze a paytable, please be aware that it will take up to 5 minutes to analyze the game.
