2-7 Single Draw is a five card draw game in which the low poker hand always wins the pot. As with Five Card Draw, a player can draw no cards or all five of the cards in their hand. Like the name implies, players will have a single round for drawing new cards if the player wants.
Unlike in Hi/Lo games where flushes and straights don't count, in 2-7 Draw they do count and aces are always high. Making the best hand 7-5-4-3-2, not 5-4-3-2-A as in Hi/Lo games.
The game is played with a small and big blind. Every player receives five cards, face down. The first player to the left of the big blind acts first, and can fold, call, or raise. Action continues clockwise around the table.
After this first round of betting each player gets their turn to draw new cards if they want. After the draw round is over, the player to the left of the dealer button acts first. Action continues clockwise around the table. This is followed by the showdown.
At the showdown the player with the best 2-7 five card hand wins the pot. If more than one person has the same winning hand then the pot is split equally among them. In 2-7, flushes and straights count, and aces are always high.
