Hands "qualify" by having 5 unpaired cards, all with a rank of 8 or less. (Sometimes Omaha Hi Lo is called Omaha 8 or Better, in reference to how the low hands quailfy). When determining the winner of the "low" portion of the pot, straights and flushes are not considered. This allows straight flushes to sometimes become both the high and low hand at the table.

    This calculator determines how often an entered hand will win the high portion of the pot, tie the high portion of the pot, win the low portion of the pot, or tie for low portion of the pot. It also determines how often a hand will "scoop" the pot, winning the whole pot.

Qualifying Low Hands:
Consist of five cards with different numerical values from Ace to Eight (thus the 8 or "better"). If more than one player meets this criteria, the player with the lowest high card will win the low hand pot. (e.g. Ah, 2d, 5c, 6c 7d BEATS Ac, 2c, 6d, 7h, 8d. Straights and flushes do not count against a low hand however, since all cards need to have different numerical values, a pair is not eligible.

Any easy way to determine the lowest hand of the round is to turn each hand into a 5 digit number, from highest digit to lowest. So, A,3,4,5,7 would be read as 75,431. A,3,4,5,6 would be read as 65,431. the player with the lower number wins.

Something to keep in mind: Since players must use 3 community cards to make a low hand, if there are not 3 community cards with values of 8 or less, it is not possible for a qualifying low hand to occur during that game.

Split Pots:
The potential for split pots in Omaha 8/b is greater than in other limit games. First, if a game has both a high hand and a qualifying low hand at the showdown, the pot will be split between the winning hands. It could be split further if multiple players have the same hand evaluation for either the high hand and/or the low hand.
