Players and cards
For 2–6 players use an ordinary 52-card pack without jokers. Each receives 5 private cards and no community cards. Select fixed-limit 2/4 notional chips, blinds 1/2, no ante or rake. Everyone starts with 100; no chips may be added during a hand. This is specifically 2–7 lowball: A is always high and straights and flushes hurt. The seven in the name is not a maximum qualifying rank.

Comparing low hands
From best category to worst: unpaired, one pair, two pair, trips, straight, flush, full house, quads, straight flush. For unpaired hands sort all 5 ranks descending and compare in order: the lower first differing rank wins. Best is mixed-suit 7–5–4–3–2; 7–6–4–3–2 loses on 6 against 5. Only all cards sharing a suit makes a flush; a repeated suit alone does not. A–5–4–3–2 is not a straight but is A-high; an ordinary unpaired K-high beats it.
Within a category compare repeated ranks first: a lower pair, triple or quad is better. With two pair compare the higher pair, lower pair, then kicker; with full houses compare triple then pair. Compare remaining cards descending, lower being better. Straights and straight flushes compare their top; flushes compare all ranks descending. Suits never break ties.

Deal and opening
Choose the first button by lot; after each hand move it left to the next player with chips. The left neighbour posts small blind 1, the next big blind 2. Deal 5 hidden cards each, singly clockwise. First betting starts left of the big blind. Blinds count towards the wager; the big blind retains the option to raise after mere calls. Heads-up, the button posts the small blind and acts first before drawing; the other posts big blind. Draws and later betting start with the active player left of the button, the big blind heads-up.

Four betting rounds
The sequence is bet, draw, bet, draw, bet, draw, final bet and showdown. Bets and each raise are 2 in the first two rounds and 4 in the last two. This limit profile caps a round at one bet and 3 full raises; the big blind counts as the first bet. If action becomes heads-up before the cap, raises are unlimited. A cap already reached is not undone by a later fold.
With no wager, check to remain without adding chips or bet. Facing a wager, fold to abandon all claim, call by adding the difference, or raise by calling and adding the fixed increment. Check-raising is allowed. A round ends when everyone still holding chips has responded and matched, or everyone checks. If only one player has not folded, that player takes the pot immediately without showing.

Three draws and a short pack
On each draw the remaining players, including all-ins, announce clockwise from the button’s left how many cards they discard, from 0 to 5. Zero means stand pat, keeping everything; it does not prevent drawing later. Keep discards hidden and separate. Burn 1 hidden card before replacements, even when everyone stands pat. Give each player all replacements consecutively, restoring a hand of 5.
For this live table agree the following shortage procedure: shuffle the stub with previous discards and folded hands; current discards of already served players may join, but exclude those of the current recipient and players still waiting. Never touch live hands. Burn cards stay out. Repeat if necessary. A card discarded on an earlier personal draw may return after reshuffling; this expressly differs from PokerStars’ electronic protection.

All-in and reopening
Insufficient chips do not force a fold: put the remainder all-in and continue drawing. But you cannot shove a large stack beyond the fixed limit. An incomplete all-in raise smaller than half the fixed increment does not reopen raising for players already acted; half or more does. After a bet of 4, all-in to 6 adds 2 and reopens action: the next full raise adds 4, to 10. An incomplete increase of 1 would not reopen it. A player yet to act retains legal raising rights; a less-than-half increase may be completed to the full level.

Scoring
Return any uncalled excess to its owner. Separate main and side pots by contribution levels: an all-in player may win only covered levels; folded contributions remain but their owners cannot win. Contributions of 6, 10, 10 create a main pot of 18 for all and a side pot of 8 for the latter two. Compare each pot separately using the complete 5-card hand. There is no “seven or better” qualifier: if everyone has pairs, the best of those hands wins.
08 /
Ending the game
After final betting show all hands claiming a pot: the last aggressor shows first, or without a final bet the first active player left of the button. Equal ranks split the relevant pot equally; this home agreement gives an indivisible chip to the first tied player left of the button. When all-in ends betting, remaining draws still occur. For a session play 10 hands or until only one player holds chips; skip eliminated players. Most chips at the end wins, ties share place. Shuffle the full pack before every new hand.

History and selected variant
2–7 is a low-poker ranking system also called Kansas City lowball. Triple Draw supplies three exchange opportunities and four betting rounds; it is not four-card, different-suit Badugi. Sources document modern tournament and online play but do not establish a sole inventor reliably. This describes a live table with expressly selected recycling, raise-cap and session-end procedures; operator versions may differ.

Worked example
A holds 2♣ 3♦ 4♥ 7♠ K♣. On the first draw discard K♣ and receive 5♦, making the best 7–5–4–3–2 without a flush. A stands pat on later draws but still participates in betting. B shows 7♥ 6♣ 4♠ 3♣ 2♦ and loses on 5 against 6. In a separate side-pot example A contributed 6, B and C 10 each: A’s best hand wins only 18; the better hand between B and C wins 8.
