Lucky Suit Poker

Lucky Suit Poker is a unique game which has five suits instead of four. Flush-type hands in the fifth suit, Clovers, are generally worth more than the same hand in one of the four regular suits. The Ten, Jack, Queen, King and Ace of Clovers can also be used to create a Wild Royal Flush when mixed with Royal Flush cards from one regular suit.

Because of the extra suit, the simplified deck is not as simple as it is for most games. 7,716,007 of the 8,259,888 hands are redundant and therefore do not need to be analyzed, but this leaves well over 500,000 hands that do need to be analyzed. If you run a strategy guide or analyze a paytable, please be aware that it will take at least 5 minutes to analyze the game.
