Lowball is a form of draw poker played for the lowest hand. Most Lowball games have a blind structure somewhat like Hold'em while others have an ante. When played with limits (like 5/10), the bet doubles after the draw. Each player receives five cards face down, and play on the first round starts to the left of the big blind with blinds or left of the dealer with antes.
With blinds, each player must call the big blind (some games require the minimum opening bet to be double the big blind), raise, call a raise, reraise, or fold. With antes, each player may check, bet, call the bet, raise, or fold. After this first round of betting, remaining players may trade any number of their cards for new ones (some games limit the number of cards players can draw). The final round of betting starts after the draw with the player to the left of the dealer. There are many different and unique rules that some card rooms use and others do not. It is advisable to read the posted rules and/or ask a floor person for them before entering a Lowball game.
Ace-to-five lowball: A-2-3-4-5 is the best hand in Ace-to-Five Lowball. Flushes and straights do not count against you. Many Ace-to-Five Lowball games are played with a joker, which is used as the lowest possible card. The joker, however, cannot match any card in your hand.
Deuce-to-seven lowball: The best hand in Deuce-to-Seven Lowball is 2-3-4-5-7--not all of the same suit. Flushes and straights count against you. The name deuce is what many players call a two. An ace is considered only as a high card and cannot be used as a low card.
When you want a break from hold'em and stud poker, it's always nice to come back to draw poker. The chance to trade up for better cards has timeless appeal.
