In most poker games, the best hand wins. Most but not all. In a number of games, the worst hand wins all or some of the pot. Draw lowball and razz are just two examples of games played for low. Omaha and seven card stud have popular high-low split variants, in which the low hand gets half the pot. There are two common ways to evaluate low hands. In deuce to seven games, the best low hand is just the worst high hand. The best possible low is 75432, provided there is no flush. In ace to five games, straights and flushes don't count, and aces are lower than 2's. So the best possible low is A2345, a wheel.
