What is Eight-or-Better in Poker?

Eight-or-Better is a qualifier for certain poker variants in which the object is to make the best low hand with cards that are all 8 or lower.

The most commonly played eight-or-better games are Omaha 8 and Seven-Card Stud 8 (aka Omaha Hi-Lo and Seven Card Stud Hi-Lo). In both of these games, players are trying to make the best possible five-card high hand, as well as the best possible five-card low (eight-or-better) hand at the same time from their seven total cards.
