Omaha poker is a poker game. It is similar to Texas Hold 'Em in that it involves a combination of hidden hole cards dealt to each player, and community cards shared by all players. In Omaha, players are dealt 4 cards, rather than 2 as in Hold'em, and must use exactly two hole cards, whereas Hold'em allows players to use 1 or none. It is commonly played in both High only, and Hi-Lo formats. The betting limits are typically fixed limit, or pot-limit. No-limit Omaha is fairly rare.
