Omaha follows the same basic rules as Texas Hold'em, but with a twist in the number of hole cards dealt.
Hole Cards: In regular Omaha each player is dealt four cards face down. In 5-card Omaha (PLO5), and 6-card Omaha (PLO6) each player is dealt five or six cards face down respectively.
Players must use exactly two hole cards and three community cards to form their best five-card hand.
The player with the best hand, or the last player remaining after others fold, wins the pot. The same hand ranking system as Texas Hold'em applies here.
