What Are The Rules Of An Omaha Poker Game?

Table of Contents


Omaha Hold'Em

Omaha is a variant of Hold'Em games in which players are dealt four hole cards that they can mix with five community cards to make their best five-card hand. Omaha is very particular: players must use exactly two cards from their hand plus exactly three cards from the board to make their best five-card hand. This can take a while to wrap your head around, but after a little bit of practice, you'll be able to see what hands you can make.

Because Omaha has a lot of hole cards that can mix with the board in lots of combinations, it's a popular game for math-minded players who can calculate odds of many different kinds of draws hitting.

Want even more draws? Omaha High/Low is a hugely popular variant, in which players can make the best high hand and the best low hand: the best high hand takes one half, and the best low hand takes the other.

As a result of Omaha's popularity, as well as the popularity of High/Low, many poker rooms offer Omaha tables, Omaha High/Low tables, and the two games make up the O (Omaha) and E (Omaha High/Low, also called Omaha Eights-or-Better) in HORSE.

Betting Structure

Like Texas Hold'Em, Omaha is a blinds game: before any cards are dealt, the small blind is posted by the player to the left of the dealer (half the minimum bet) and the next player posts the big blind (the minimum bet). Antes might be used late in tournaments to force action.

Also like Texas Hold'Em, players can choose any betting structure they like when playing Omaha: limit, no-limit, and pot-limit. But unlike Texas Hold'Em, Omaha is more popularly played pot-limit rather than no-limit.

  • No limit is simple: At any point, a player can bet their entire stack.
  • Limit a little more complicated: players bet in set increments, and there is a cap on the number of bets or raises allowed in a given round of betting (usually three). The limit might go up in later rounds of betting.
  • In pot-limit, the maximum bet is equal to the number of chips already in the pot. This means early bets are smaller, but can get exponentially bigger as the pot grows. Pot-limit is a popular variant for Omaha players because it makes calculating pot odds easy, a pot-sized bet means a player is getting 2:1 odds to call.

Dealing a Hand

Players post their blinds. The dealer deals four hole cards. In the first round of betting (pre-flop), the action begins with the player to the left of the big blind: call, raise or fold. The action moves to that player's left. After the dealer acts, the action comes back around to the small blind, who can call, raise, or fold. If the blinds haven't been raised, the big blind can check (remember, never fold if checking is an option!) or they can call, raise, or fold

Three cards are dealt face up (the flop). Another round of betting, followed by another card dealt face up (the turn). Another round of betting, followed by the fifth card dealt face up (the river). A final round of betting.

If someone bets and no one calls, the bettor wins the pot. If someone bets and gets called, they show their hand, and players to their left either show their hand or mucks, the best five-card hand wins the pot. If no one bets on the last round, the first player to the left of the dealer shows their hand, and players to their left either show or muck.

Remember, Omaha uses the best five-card hand made from exactly two hole cards and exactly three board cards. In other words, having four of a kind in the hole is actually bad, you only play two of them as a pair!

See below to determine how to award the pot if playing Omaha High/Low.

About High/Low

Omaha High/Low gives players the chance to make the best high hand or the best low hand, with either taking half the pot.

Omaha High/Low uses Ace-to-5 low rules: to make a low hand, you must have five unpaired cards under 9, but straights and flushes don't count against you. Therefore the best low hand is A, 2, 3, 4, 5.

A player can make a high hand and a straight hand to try to win both halves of the pot. So a player can use two cards from their hand to make a Full House with the board, and then two other cards to make a low hand.

If two players have the same high or the same low, they split the half of the pot that hand wins. So, if two players both have an A-to-5 straight, they each get one quarter of the low, but another player might win the high because they have a flush. This is sometimes getting quartered, usually, if a player loses one half of the pot and then splits the other, but it can get very crazy very fast if there are a lot of players with the nut low and one player taking the high!

Variants

  • High/Low Declare: Instead of always playing for both the high and the low, some versions of Omaha High/Low have players choose to play for one, the other, or both. This means if a player declares that are playing for the low, they cannot win the high, even if they had the better high hand, and if a player declares both, they have to win both to take both halves. Sometimes players declare by holding a chip in their hand and revealing it during showdown, other times, they take turns declaring it out loud after the last round of betting, so that the last player to declare might have a tough decision to make.
