At a first glance, Omaha poker looks a lot like Texas Hold'em. But in Omaha poker game, each player receives four cards - this gives Omaha an interesting complexity.

In Omaha poker, you get four hole cards, cards that the other players cannot see. Then, successively during the hand, five cards are dealt face up on the board. They are community cards that all players can use to put together a five card poker hand. When all cards are out, you must use two of your hole cards and combine them with three community cards in order to form the best possible Omaha poker hand.

Whenever two or more players have the same five card hand, the pot is split evenly between the players involved. If the pot can not be split perfectly, the odd extra amount will be awarded to the player nearest to the Small Blind position from a clockwise view.

Omaha Hi/Lo poker is played exactly the same way as Omaha, with one exception: in the showdown, the highest hand wins only half the pot, while the other half is won by the best low hand.

However, this is true only if an Omaha Hi/Lo player shows down a qualifying low hand. If there is no qualifying low hand, the best high hand wins the whole pot.

To qualify as a low hand, a hand must not contain any card higher than 8, and no pair or better.

However, straights and flushes do not disqualify a low hand. So, for example, 8s-7s-6s-5s-4s qualifies as a low hand. (At the same time, it is a very strong high hand, a straight flush.)

As in Omaha, you must use two of your hole cards to form a poker hand with three cards from the table. But you are free to use any combination of two cards for the low and the high hand. One or two of your hole cards may be used for both the high and the low hand, or you may use two cards for the high hand and the other two cards for the low hand, as you wish.

For example, if you hold AKT2 and the board is AA764, your best high hand is AK+AA7 (three of a kind), and your best low is A2+764. You use the ace in both hands.

In Omaha Hi/Lo, the ace is the highest card, but it is also the lowest. This is what makes the classic hand A2345 ("the wheel") so strong. It is the best possible low hand, but at the same time, being a straight, it is a strong high hand.

Each of the two halves of an Omaha Hi/Lo pot can be split further if two or more players have an equal low or high hand. For instance, if two players have an equal high hand and only one player has a qualifying low hand, the players with the best high hand will each win 25% of the pot while the sole low hand winner will win 50% of the pot. In the case that a pot can not be split perfectly, the odd extra amount will be awarded to the player nearest to the Small Blind position from a clockwise view.
