Kansas City Lowball
Form of lowball poker in which the worst poker hand (2, 3, 4, 5, 7 of different suits) is the best hand. It's also known as Deuce to Seven.
In ace-to-five lowball, the hand 7-5-4-3-2; so called, because that is the best hand in Kansas City lowball. In ace-to-five lowball, when used attributively with a rank, generally means that card plus 5-4-3-2. For example, a Kansas City 8 is the hand 8-5-4-3-2.
