As the name implies, the game is loosely based on poker and is designed to be played using Playing Cards, but D20s or D12s can be substituted with only a slight change in the odds. For the cards, Aces are worth 1, while face cards have a numerical value: Jacks are 11, Queens 12 and Kings are worth 13. How Jokers are used will be explained below.
Obviously, these rules only barely scratched the surface with what you can do with the cards. Dealers are encouraged to tinker, fiddle and warp the system in whatever way they see fit. Players are encouraged to do the same in the Extras category (see below).
Players start off with 50 points to distribute between five categories: Combat, Mental, Physical, Accouterments and Extras. There is also an optional fifth category called Flaws that may awards extra points. Players MUST put points into Combat, Mental and Physical. Characters that do not allot points for Accouterments start the game only with the most basic of equipment. In a fantasy game this would mean the clothes on their back, enough pennies for a meal or two and a rusty dagger, while in a science fiction game, it might mean the clothes on their back and a pocket zapper with only a small charge left. For Extinction Event, a character with no points in Accoutrements (depending on the viciousness of the Dealer) could easily start the game completely naked.
