Omaha High Poker uses what is called a dealer-button to indicate the theoretical dealer of each hand. After each hand is completed, as with standard poker rules, the button moves clockwise to the next active player. This player will be considered "the dealer" for that hand.

Players start with four "down" cards, and share five "community" cards (which are dealt face-up in the center of the table). You MUST use two of your four "down" cards along with three "up" cards (community cards) to form your hand. Upon completion of betting, the best hand wins the pot. The pot may also be won by someone betting and no one calling prior to the completion of the hand.

There are four betting rounds in Omaha Poker. In Omaha High and Omaha 8 or Better, one bet and three raises are allowed per betting round. To continue to play, players must act on each betting round (unless they are "all-in"). Betting always proceeds in a clockwise rotation.

Prior to dealing the cards, two blinds (the Small Blind and the Big Blind) are placed in the pot by the two players to the immediate left of the dealer (indicated by the dealer button). The blinds are put in to start the action.

Everyone is dealt four "down" cards. The player to the left of the Big Blind then folds, calls, or raises. Play continues with all players making one of these decisions. This is the first betting round.

Upon completion of the first round of betting, three cards are dealt face-up in the center of the table (community cards known as "the Flop"). This is the second round of betting. Beginning with this round of betting, and throughout the remaining rounds of betting, the player to the left of the dealer button acts first. A player may now Check or Bet (if there is no betting in front of them). If there is betting and/or raising in front of them, they may Call, Raise, or Fold.

Upon completion of the action on the "flop," another card is dealt face-up (known as the "The Turn" or "Fourth Street"). This is the third betting round. The size of the bet doubles on this round of betting. The betting again starts with the player closest to the left of the button.

Following the completion of action on "the turn", the dealer turns over the last card (known as "The River" or "Fifth Street"). This is the final round of betting.

Upon completion of the final round of betting, the best hand wins the pot.
