2-7 triple draw makes for an interesting variation. In this poker game, the best hand is the worst hand. It differs also from other low games – aces are high and straights and flushes count against a player's low hand. So what you need is the lowest possible hand. It's a form of draw poker and the difference, as the name suggests, is that you have the chance to draw cards three times instead of once.
With that in mind the simplest way to determine who has the worst hand at showdown is to start with a player's worst card (their highest ranking card) and work backwards. If one player holds 9,8,6,3,2 and another has 9,8,6,4,2 and both have no possible flushes, the first of these two hands would be declared the winner (as the 3 is lower than the 4).
As for the best possible hand in triple draw that would be 7,5,4,3,2 avoiding a flush (notice it also misses the straight). If each player involved in a showdown has a pair (this is rare) then the player with the lowest pair would win the hand. It's also worth noting that A,2,3,4,5 is not a straight as the ace is high. It's not a strong hand but will beat an opponent with a pair or a straight on the last draw.
In 2-7 Triple Draw, a marker called 'the button' or 'the dealer button' indicates which player is the nominal dealer for the current game. Like all draw games, 2-7 is played with blinds which are posted by the player on the left of the dealer (known as the small blind), and the player second-left from the dealer (the big blind). Once this is done each player is dealt five cards face down. Unlike many other poker games, each player can see his – and only his – cards. There are no community cards.
In the first round of betting, the player sitting to the left of the big blind has the option to fold, call or raise. Each player has the same options and the action continues until the blinds have acted (these players also have the option to raise, even if there is no raise in front of them as their blinds, or bets, are 'live'). In Limit games, the raise is limited to one small bet. In Pot Limit the maximum raise is the pot (the amount currently in the pot, plus his call), whereas in No Limit the maximum raise can be any amount of chips.
After this first round of betting there is a draw. Each player selects which cards he wishes to discard (if any) by clicking on them. He can discard all the cards if he wishes. Clicking once chooses that card to be discarded, clicking twice cancels this decision. Discarded cards are then replaced by new cards appearing in your hand.
This continues for each player in a clockwise direction around the table. When it is your turn you press the button which confirms you wish to discard the cards selected. Choosing to 'stand pat' means you are happy with the five cards you have been dealt and do not wish to change any.
Now it's time for the second round of betting. The first player to the left of the dealer who has not yet folded is the first to act and the action continues in this fashion, until the betting is over for that round.
With betting done those players still active draw cards for a second time, following the same procedure. A third round of betting now occurs, the player to the left of the dealer still active in the hand being first to act. Then comes the third and final draw and another round of betting.
Now comes the showdown. The player with the best five card 2-7 low hand after the final round of betting is awarded the pot. If two players have the same winning hand then the pot is split evenly between them (note that suits make no difference in this case).
In draw games, it is possible for more cards to be needed than are remaining in the deck. In this case, the cards are reshuffled, and play continues using the new deck.
