2-7 (Deuce to Seven) Triple Draw is a poker game in which the low poker hand wins the pot at showdown. In other words, it is a form of "lowball". It is a "draw" game, meaning that you are dealt five cards, and may discard from zero to five of them on the draw, and receive that number of replacement cards. In Triple Draw, each player has the opportunity to draw three times, though you may "stand pat" (not discard any cards) on any or all of the draws.

In 2-7, straights and flushes count against your low hand, and aces are always high. So the best possible hand is: 7, 5, 4, 3, 2. The following 2-7 hands are ranked from least powerful (#1, which will rarely win the pot) to most powerful (#16, the nuts):

1. J, 7, 4, 3, 2 (all the same suit - a flush)
2. 8, 7, 6, 5, 4 (a straight)
3. 7, 6, 5, 4, 3 (a lower straight)
4. 5, 5, 5, 6, 3
5. 2, 2, 7, 6, 5
6. A, 9, 6, 4, 2
7. A, 8, 7, 4, 2
8. A, 5, 4, 3, 2 (not a straight - ace-high)
9. K, J, 8, 7, 4
10. T, 7, 5, 4, 3
11. T, 6, 5, 4, 3
12. T, 6, 5, 4, 2
13. 9, 7, 6, 4, 3
14. 8, 6, 4, 3, 2
15. 7, 6, 4, 3, 2
16. 7, 5, 4, 3, 2

RULES

Draw games are played with blinds, just like flop games. Each player is dealt five hidden hole cards. The first player after the big blind has the option to fold, call, or raise. Action continues clockwise around the poker table until betting is complete for the round.

Once the first round of betting is complete, there is a draw. That is, each player selects which (if any) cards he wishes to discard by clicking on them. By clicking a second time on a card that you have planned to discard, you remove it from the discard set. Discarding continues around the table clockwise. When it is your turn to discard, you press the button to confirm you wish to discard the selected cards.

After the first draw, there is another round of betting, beginning with the first active player to the left of the button.

There are two more draws with a round of betting following each one, resulting in three draws total, and four rounds of betting. So the sequence of action is:

1. Five cards dealt to each player
2. Betting round #1, beginning with player to left of big blind
3. Draw #1
4. Betting round #2, beginning with player to left of button
5. Draw #2
6. Betting round #3, beginning with player to left of button
7. Draw #3
8. Betting round #4, beginning with player to left of button
9. Showdown (if necessary)
