Omaha poker high low

Omaha poker high low is a split-pot variant of Omaha in which the pot is divided between the best high hand and the best qualifying low hand.

Low qualifier
8-or-better: five different ranks all 8 or lower; aces count low, straights and flushes ignored for low.2
Hand construction
Each player uses exactly two hole cards and exactly three community cards.1
Pot split
If no one qualifies low, the high hand wins the whole pot.2

Key points

  • Also called Omaha/8, Omaha Eight or Better, or Omaha HiLo.1
  • Each player makes both a high and a low hand at showdown using the same two hole cards and three board cards.1
  • Aces are low for the low hand, and straights and flushes do not disqualify a low hand.2
