Deuce-to-Seven
Deuce-to-seven is a lowball game in which the best hand is 7-5-4-3-2 and aces are high.
The simple explanation
In deuce-to-seven, you want the lowest hand, and straights and flushes count against you. Aces are always high. The best possible hand is 7-5-4-3-2 without a flush. It is the opposite of high poker: you want your cards to be as low and disconnected as possible.
A closer look
The game is usually played as triple draw, with three draws, or as single draw. Because straights and flushes are bad, the best low is 7-5-4-3-2 in mixed suits. Compare it with ace-to-five lowball, where the best hand is the wheel. Because aces are high, a hand with an ace is weak. The game appears in mixed rotations such as the 8-game.
A practical example
A player holds 7♠ 5♦ 4♣ 3♥ 2♠ which is the best hand in deuce-to-seven.
Full explanation
Deuce-to-seven is a lowball game in which the best hand is 7-5-4-3-2 and aces are high.
Deuce-to-seven is a lowball format. The best hand is 7-5-4-3-2 that is not a straight or a flush. Aces are high, so any ace makes your hand worse.
It is played as single draw or as triple draw, with betting rounds between draws.
The scoring differs from ace-to-five lowball, in which aces are low and straights and flushes do not count. In deuce-to-seven they count against you.
The game is part of mixed game rotations such as the 8-game. The single draw version is also known as Kansas City lowball.
