Both players receive 12 cards from the deck. The idea is to defend the "good combination" of your cards from the opponents shooting, and to shoot down cards "combinations" from the opponent's hand. Last 5 cards, that remain at players hand at the end of the set, define the final poker combination at the hand. If your combination is higher than opponent's, you go level up. If lower - level down.
You have a special "Poker Gun". You may shoot with this gun, to destroy cards at opponent's hand. And also, you may defend with this gun your cards (at the bottom). Move the gun left-right and click to shoot. The set finishes when both players have last 5 cards at their hands.
: Drag your (bottom) gun left-right, and click to shoot.
Oops!.. LEVEL DOWN!
