Omaha is not very dissimilar to Texas Hold'em, as this poker game also uses a three card flop, followed by a fourth board card and then a fifth board card. Betting rounds are also the same as in Hold'em.

However, in Omaha each player is dealt four hold cards, and they must use two of these and three of the board cards to make their hand. It is therefore not possible to "play the board" (use the community cards only) as one can in Texas Hold'em. To claim a pot in Omaha, players must show all four of their hole cards, and not just the two they are using to make their hand.

14.1 All of the rules presented in Section 13 for Texas Hold'em apply to Omaha with the exception of Rule 13.10. This is because Omaha players must use two of their four hole cards and three of the board cards to make up their hand, and are not permitted to make a hand from the five board cards only.
