Omaha is a community card game with four betting rounds.
Game Play
One player is the dealer; this position is called the button (the dealer position moves clockwise after every hand).
The two players to the left of the dealer are the small blind and the big blind. They are the only players who have money in the pot before the cards are dealt.
Every player receives four cards face down, called hole cards.
The first betting round begins with the player sitting to the left of the big blind and continues clockwise.
When the first betting round is finished three community cards are flipped face up on the table, this is called the flop.
The second round of betting begins with the first player left of the button and who is still in the hand. The betting continues clockwise.
When the second round of betting is finished a fourth community card is flipped face up on the table, this is called the turn.
The third round of betting begins with the first player left of the button and who is still in the hand. The betting continues clockwise and the bets are doubled on the turn.
When the third round of betting is finished a fifth community card is flipped face up on the table, this is called the river.
The fourth round of betting begins with the first player left of the button and who is still in the hand. The betting continues clockwise.
How to make a hand
In order to make a hand the players combine their hole cards with the community cards on the board to make the best 5-card poker hand. One must use two of the hole cards and three of the community cards when making a hand.
