2-7 Triple Draw Rules

Deuce-to-Seven is a lowball draw game: the lowest five-card hand wins. Aces count only as high, and straights and flushes count against you, so the best possible hand is 7-5-4-3-2 of mixed suits. In Triple Draw, players get three draws and four fixed-limit betting rounds; in No-Limit Single Draw, they get one draw and two betting rounds.

Article 1Objective and equipment

1.1

The object of the game is to win the pot, either by holding the lowest five-card hand at showdown under the Deuce-to-Seven ranking in Article 2, or by making a bet that no other player calls.

1.2

The game is played with a standard 52-card deck with no jokers. Suits have no rank.

1.3

Every player's hand consists of the five cards they hold. There are no community cards and no cards are dealt face up.

1.4

Triple Draw is normally played with no more than six players, because each player may replace up to fifteen cards over three draws. No-Limit Single Draw is normally played with up to seven players.

1.5

Deuce-to-Seven is also called 2-7 lowball or Kansas City lowball. It is a different game from Ace-to-Five lowball, used in Razz, in which aces are low and straights and flushes do not count.

Article 2Deuce-to-Seven hand rankings

Deuce-to-Seven turns the standard hand rankings upside down. The hand that would lose in ordinary high poker wins.

2.1

Hands are ranked by the standard poker hand rankings, and the lowest-ranking hand wins. A hand with no pair, straight or flush beats any hand with a pair; any pair beats two pair; and so on up to a straight flush, which is the worst hand possible.

2.2

Aces are high only. An ace is always the highest card. A hand containing an ace and no pair is an ace-high hand, which is a poor holding. A-2-3-4-5 is not a straight; it is ace-high.

2.3

Straights and flushes count. Five cards in sequence are a straight, and five cards of one suit are a flush. Either one ranks above every no-pair hand and every pair, and so loses to them.

2.4

Comparing no-pair hands. Two no-pair hands are compared by their highest card; the lower highest card wins. If the highest cards are equal, the next-highest cards are compared, and so on down to the fifth card.

2.5

Hands that each contain a pair or better are compared as in high poker, and the weaker hand wins. A pair of twos beats a pair of threes; a pair of twos with a lower set of side cards beats a pair of twos with higher side cards.

2.6

If two hands are identical in rank, the pot is split equally.

The best Deuce-to-Seven hands (none may be all one suit)
RankHandName
1 (best)7-5-4-3-2"Number one", the nuts
27-6-4-3-2Seven-six
37-6-5-3-2Seven-six-five
47-6-5-4-2Worst seven
58-5-4-3-2Best eight
68-6-4-3-2Eight-six
78-6-5-3-2Eight-six-five
88-6-5-4-2Eight-six-five-four

Note that 7-6-5-4-3 does not appear: it is a straight. Likewise 8-7-6-5-4 is a straight, while 8-6-5-4-3 is a no-pair hand and ranks immediately below 8-6-5-4-2.

Example

Comparing two eights

Player A shows 8♠6♦4♣3♥2♠. Player B shows 8♣5♥4♦3♠2♦.

Both hands are eight-high, so the second cards are compared. B's five is lower than A's six, so Player B wins with 8-5-4-3-2.

Example

A wheel is not a straight, and a straight is not low

Player A shows A♥5♣4♦3♠2♥: ace-high with no pair. Player B shows K♦Q♠J♣9♥8♦: king-high with no pair. Player C shows 7♣6♠5♥4♥3♦: a seven-high straight.

King-high is lower than ace-high, so Player B wins. Player C's straight loses to both no-pair hands.

Article 3The button and the blinds

3.1

A dealer button marks the nominal dealer and moves one seat clockwise after each hand.

3.2

The player directly to the left of the button posts the small blind and the next player posts the big blind. Blinds are live bets, and the big blind has the option to raise if no one else has.

3.3

In fixed-limit Triple Draw, the big blind is equal to the small bet, and the small blind is usually half of it. In No-Limit Single Draw, tournaments commonly add an ante from every player or a big blind ante.

3.4

Heads-up play. With two players, the button posts the small blind, acts first before the first draw and last on every later round.

Article 4Triple Draw: betting rounds and draws

In Triple Draw there are four betting rounds, separated by three draws. The game is almost always played fixed-limit.

RoundWhen it happensBet sizeFirst to act
FirstAfter the dealSmall betThe player to the left of the big blind
SecondAfter the first drawSmall betFirst active player to the left of the button
ThirdAfter the second drawBig betFirst active player to the left of the button
FourthAfter the third drawBig betFirst active player to the left of the button
4.1

The big bet is twice the small bet. In a 200/400 game, bets and raises on the first two rounds are 200, and on the last two rounds 400.

4.2

Each round is capped, most commonly at one bet and three raises. Many venues remove the cap when only two players remain in the hand. See betting structures.

4.3

After each betting round, starting with the first active player to the left of the button, each player in turn discards any number of cards from none to five, face down, and receives the same number from the deck.

4.4

A player who stands pat on one draw may draw on a later one. There is no requirement to draw, and no limit on the number of cards drawn other than five per draw.

4.5

If all but one player folds at any point, the remaining player wins the pot at once and need not show their cards.

Article 5The draw and the reshuffle

5.1

A player shall declare the number of cards they want and discard them before receiving replacements. Once replacement cards have been dealt to a player, the number drawn may not be changed.

5.2

Discards are dead and may not be retrieved.

5.3

A card exposed by the dealer during the draw may not be taken by the player. It is placed with the discards and replaced. Venues differ on whether the replacement is dealt at once or after every other player has drawn.

5.4

Until there has been action after a draw, a player may ask how many cards an opponent took on that draw, and the dealer or that opponent shall answer.

5.5

Reshuffle. The last card of the deck shall not be dealt. When the remaining cards cannot complete a draw, the dealer deals as far as possible without using the last card, then gathers all the discards, the burn cards and the last card, shuffles them, has them cut, and completes the draw from the new stack.

5.5(a) The discards of the player currently drawing, made on this draw, are not included in the reshuffle. That player shall not receive their own discards back.

5.5(b) In most cardrooms the dealer burns a card from the new stack before continuing. The venue's procedure governs.

Example

The deck runs short on the third draw

Six players reach the third draw and only four undealt cards remain. Player E asks for three. The dealer deals E three cards; the last card is now the only one left.

Player F asks for two. The last card is not dealt. The dealer sets aside F's two discards, shuffles every other discard with the burn cards and the last card, has them cut, and deals F two cards from the new stack.

Article 6A Triple Draw hand, step by step

  1. The button is placed. The two players to its left post the small and big blinds.
  2. Each player is dealt five cards, face down, one at a time.
  3. First betting round (small bet), starting left of the big blind.
  4. First draw, starting with the first active player left of the button.
  5. Second betting round (small bet), starting with the first active player left of the button.
  6. Second draw.
  7. Third betting round (big bet).
  8. Third and final draw.
  9. Fourth betting round (big bet).
  10. If two or more players remain, there is a showdown and the lowest hand wins.
  11. The button moves one seat to the left, and the next hand begins.

Article 7Showdown

7.1

If more than one player remains after the final betting round, the last player to bet or raise on that round shows first. If there was no bet, the first active player to the left of the button shows first.

7.2

The cards speak. Hands are read from the cards shown. A player who miscalls a hand does not lose a pot their cards win, but a player who misdeclares a hand in a way that causes another player to discard a winning hand may have their hand declared dead at the floor's discretion.

7.3

A player with more or fewer than five cards at showdown has a dead hand.

7.4

When a pot cannot be split evenly, the odd chip goes to the first player in the tied hand to the left of the button.

Example

A pair against a no-pair hand

Player A shows 2♣2♦3♥4♠5♣, a pair of twos. Player B shows Q♦J♠9♣6♥4♦, queen-high.

Any no-pair hand beats any pair. Player B wins with queen-high.

Article 8No-Limit Single Draw (Kansas City lowball)

No-Limit 2-7 Single Draw uses the same hand rankings but only one draw, with two no-limit betting rounds.

8.1

Blinds are posted as in Article 3, and in tournaments an ante is usually added. Each player is dealt five cards face down.

8.2

The first betting round begins with the player to the left of the big blind. Betting is no-limit: the minimum bet is the big blind, a raise must be at least the size of the previous bet or raise on the round, and a player may bet all of their chips at any time.

8.3

After the first betting round, each active player in turn, starting left of the button, may discard and replace from none to five cards. There is one draw only.

8.4

A second betting round follows the draw, starting with the first active player to the left of the button. Showdown follows the rules in Article 7.

8.5

An all-in wager that is less than a full raise does not reopen the betting to players who have already acted and are facing only that short amount.

8.6

Rules 5.1 to 5.5 on the draw, exposed cards, questions about the number drawn and the reshuffle apply equally to Single Draw.

Article 9Frequently asked questions

What is the best hand in 2-7 Triple Draw?

7-5-4-3-2 of at least two different suits, called "number one". The next best is 7-6-4-3-2. If all five cards are the same suit, the hand is a flush and loses.

Is an ace high or low in Deuce-to-Seven?

An ace is always high. A-2-3-4-5 is not a straight and not a good low hand: it is simply ace-high, which loses to any king-high or lower no-pair hand.

Do straights and flushes count in 2-7 lowball?

Yes. A straight or a flush ranks above any pair, and in lowball a higher-ranking hand loses. 7-6-5-4-3 is a straight and a poor hand.

How many betting rounds are there in Triple Draw?

Four. One after the deal and one after each of the three draws. In fixed-limit, the first two rounds use the small bet and the last two use the big bet.

What happens when the deck runs out in Triple Draw?

The last card is never dealt. The dealer shuffles the discards, the burn cards and the last card together, leaving out the discards of the player currently drawing, and completes the draw from that new stack.

What is the difference between 2-7 and A-5 lowball?

In Deuce-to-Seven, aces are high and straights and flushes count, so the best hand is 7-5-4-3-2. In Ace-to-Five, aces are low and straights and flushes are ignored, so the best hand is 5-4-3-2-A.
