In high-low split, each player is dealt four cards and must make his best hand using exactly two of them, plus exactly three of the five community cards.
Each player makes a separate five-card high hand and five-card ace-to-five low hand (eight-high or lower to qualify), and the pot is split between the high and low (which may be the same player). To qualify for low, a player must be able to play an 8-7-6-5-4 or lower (this is why it is called "eight-or-better", or simply "Omaha/8"). Each player can play any two of his four hole cards to make his high hand, and any two of his four hole cards to make his low hand. If there is no qualifying low hand, the high hand wins (scoops) the whole pot.
