Omaha or Better (also known as Omaha Hi-Lo) is one of the most popular poker games in the world, behind the one and only Texas Hold'em. Usually there are two types of Omaha or Better games played:

Limit Omaha or Better (specific betting limit applied to each game and on each round of betting)

Pot Limit Omaha or Better (playerw can bet what’s in the pot)

The game:

Omaha or Better poker usually uses what is called a “dealer button” to indicate the theoretical dealer of each hand. After each hand is completed, as with standard poker rules, the button moves clockwise to the next active player. This player will be considered “the dealer” for that hand. As a rule (if not indicated otherwise), a single deck of cards is used, consisting of 52 cards, excluding the jokers.

First round:

A fresh game starts with the first person sitting at the table becoming the dealer and the next player—the player to the left of the dealer—posting what’s called “the small blind.”

The small blind, officially, is equal to half of the lower stake at any given table, but this is only a guideline and NOT a strict rule. What usually happens is that the small blind is rounded down to the nearest whole dollar. For example, if you’re playing at a $5/$10 Omaha or Better table, you would expect the small blind to be $2.50. In actuality, the small blind is only $2. There are different procedures at different tables, so be sure you know what you’re expected to do. Rounding down, however, is very common in most online poker rooms.

Moving on: the player to the left of the small blind is required to post “the big blind,” equal to the lower stake limit. In certain scenarios it’s possible for more than one player to post a big blind in a hand. This can happen if a new player joins a table at which a game is already going on. The new player gets the option of placing a big blind at the start of the next hand or waiting for his or her turn (as decided by the movement of the button) to place the big blind in turn. Just as a reminder, all of the blinds in Omaha or Better poker are considered live bets and the players who post them have the option of checking, calling, raising or folding when the action returns to them.

After the blinds have been placed, the down cards/hole cards are dealt to each active player. As in Omaha High, four cards are dealt to each of the players in Omaha or Better, after which the first betting round begins. The player to the left of the player who placed the big blind starts the betting for the round.

Each player now has the option to place his or her bets in the first round, in which the values are set at the lower limit of the stake structure. For example, in a $10/$20 Omaha or Better game, the value of each bet is $10 for the first round. When we say that the bets are limited to $10, it refers to a SINGLE BET. In other words, a regular bet is $10 but a raise would be $20, since it includes one additional bet and a call on a player’s previous bet.

Bets can be placed by the following options: betting, calling and raising. Each player also has the option to fold. These options are available to each player depending on the action taken by the previous player. The first player to act in the first round sits to the left of the big blind, and naturally gets the bet, call and raise options first. Subsequent players get the options of call and raise only. As a reminder, calling means betting the same as what the previous player has bet. Raising means raising whatever the bet/call amount of the previous player was, and can be calculated based on the value of the previous bet.

Each player now has the option to place his or her bets in the first round, in which the values are set at the lower limit of the stake structure. For example, in a $10/$20 Omaha or Better game, the value of each bet is $10 for the first round. When we say that the bets are limited to $10, it refers to a SINGLE BET. In other words, a regular bet is $10 but a raise would be $20, since it includes one additional bet and a call on a player’s previous bet.

Every player participating in the hand should place the same bet amount as the previous players (including bets, calls and raises). The betting will continue until all players have placed equal amounts in the pot. There is, however, a limit on the amount and the number of bets a player can place during a single betting round. Check our Rules section for details on this.

After the first round of betting is over, the three community cards—A.K.A., “the flop”—are dealt. The community cards are common to all players participating in the hand.

Second round:

After the flop and in each subsequent betting round, the first active player to the left of the button, or dealer, is first to act. And just like in the first round, the second round limits the value of bets and raises to the lower limit of the stake structure. In a $10/$20 game, then, each bet is $10 for the second round, and raises are again at $20.

After the bets have been made, the fourth community card is dealt. This one’s known as “the turn.”

Third round:

The third betting round starts again with the player to the left of the button, but bets and raises are now moved to the upper limit of the stake structure (at a $10/$20 table, $20 would be the upper limit). Following the same pattern, that means that single bets are $20, and raises are $40.

After the third round of bets have been made, the fifth and final community card is dealt out. This card is called “the river.”

Fourth round:

The fourth and final round mirrors the third round. The betting structure is at the upper limits, as opposed to the lower limits used in the first two rounds. Again, that means single bets are $20 are a $10/$20 table, and raises are $40.

Some standard rules:

A maximum of four bets, including one bet and three raises, are allowed for each betting round per player.

The term “cap” is used to describe the final raise in a round, since betting is then capped and no one can make another raise. Once capped, players will have the option of calling or folding only. Folding can be done at any stage of the game. The action of folding means that the player is no longer considered part of the game, and does not have any rights over pots created on the table.

Apart from folding, a player also has the option of checking, which means that the player passes his or her turn without placing a bet. This option is not always available to the player, and depends on the actions taken by the previous player in the hand. The player HAS TO equal the amount of the bets placed by other players for each round in the hand.

Poker is typically played by “table stakes,” which means that only the chips in play at the beginning of each hand can be used throughout the hand. This means that players cannot get additional funds from the cashier while they are in the midst of a game. The table stakes rule has an application called the “all in” rule, which states that a player cannot be forced to forfeit a hand because he or she doesn’t have enough chips to call a bet.

Exceptions to betting values in each round:

A player who doesn’t have enough chips to call a bet is declared “all in.” The player is eligible for the portion of the pot up to the point of his final wager. All further action involving other players takes place in a “side pot,” which is unavailable to the player who has already gone all in.

When a player goes all in, the pot currently at the center of the table, which has contributions from that player as well as from the others, is treated as the main pot, and the player has rights over it. After the player goes all-in, however, new bets are placed in a side pot, over which only the contributing players have rights. The all-in player does not have rights over the side pot. The side pot is given to the next winning combination.

After the final round of betting, it’s time for the most exciting part of Omaha or Better poker, called “the showdown.” This refers to the action of deciding who the winner of the pot is by displaying cards from all remaining players (though this is optional and players don’t have to show their cards). Five cards are used for deciding the winning hand—two hole cards and three community cards.

In Omaha or Better, the pot is divided into “high” and “low” sides. On the high side, there’s no need to qualify: the best hand automatically wins half the pot, and could win the whole pot. To win the low side of the pot, however, you have to qualify, which is why the game is called Omaha “or Better.”

To qualify for the low side of the pot, it takes a five-card hand with different numerical values from ace through eight (with ace being the lowest). The best low hand, therefore, is ace, 2, 3, 4 and 5, which is called the “wheel” or “bicycle”. The winning low hand goes to the player with the lowest high card. For example, a player with a 2, 4, 5, 6, 7 hand has a better result than someone with ace, 2, 4, 6, 8. If two or more players have the same high card, the player with the second lowest card (or third, fourth or fifth, if necessary) wins the low side of the pot.

There is a set ranking of cards, which is used for deciding the winning combination. To view the various ranks that are possible, click here.

TIES: In the event that two or more players tie for one side of the pot, they split that side into equally divided portions. If there is an odd chip, it goes to the person closest to the left of the “button,” or dealer. Note that one player winning the high side in Omaha or Better and two players who tie for the low side is not all that uncommon.

Some things to remember:

Straights and flushes do NOT count against you when qualifying for the low side of the pot.

You are permitted to use different cards in your hand for both the high and low sides, or you can use the same cards for both sides.

In a split pot, any left-over odd chip goes to the high side of the pot.

To determine your hand(s) in Omaha or Better, you MUST play two of your four “down” cards with three of the “up” cards, or community cards. As mentioned above, you may play different cards for the high and low sides.

The suit order of the cards is not taken into account when deciding on the winning hand. Should two or more hands be absolutely identical in ranking, the rules of poker distribute the pot evenly between the two or more winning players. This applies to both play money and real money.

The rules remain the same as above for both limit and pot-limit Omaha or Better games, but there are a few exceptions:

As mentioned above, in limit Omaha or Better a maximum of four bets is allowed per player during any betting round. This includes a (1) bet, (2) raise, (3) re-raise, and (4) cap. But in pot-limit Omaha or Better there are no limits to the number of raises that a player can make. The only criteria are that you cannot raise yourself (in other words, if a player bets during a betting round, then that player has to be raised by another player in order for him or her to re-raise). If all of the other players in the hand only call or fold, a player does not have the option to raise, because the last raise was made by him or her.

Betting structure for pot-limit Omaha or Better

Minimum raise: The raise amount must be at least as much as the previous bet or raise in the same round. As an example, if the first player to act bets $100, then the second player must raise a minimum of $100 (total bet of $200).

Maximum raise: The size of the pot. The size of the pot is defined as the total of the active pot (which can either be the main pot or the side pot depending on whether anyone has gone “all in”), plus all bets on the table, plus the amount the active player must first call before raising.

As an example, if the active pot is $200 and the first player to act in the round bets $150, and the next player calls $150, the third player has a maximum eligible total bet of $800. The $800 total is made up of the $150 call and $650 raise. The $650 max raise portion is equal to the pot of $200 + first player’s $150 + second player’s $150 + the player’s own call of $150.
