Put a time limit or a number of hands limit on the game before the first hand is dealt. This is a game that's been known to go all night or at least for hours. Instead of just ending the game when it goes too long, play Omaha as the last hand. Consider playing without goal-posting. Consider playing Piranha .
Players decide if they're in, and then holds their hands, face-down, over the middle of the table.
Flip the last 2 cards on the board. Each player may use any number of cards in his hand with any number of cards on the board to create his best 5 card hand. The winner takes the pot, and the losers must match the pot for the next hand. The deal does NOT rotate. Bet after the last 2 cards are flipped over.
