Pung, Kong, and Quint: The Groups in American Mahjong

Almost every hand on the NMJL® card is built from groups of identical tiles, and they have names based on size: a pung is three, a kong is four, a quint is five. Learn these three words and the card's shorthand starts making sense.

The three groups

• Pung — three identical tiles (the card shows a digit three times, like 555)
• Kong — four identical tiles (a digit four times, like 7777)
• Quint — five identical tiles (a digit five times — needs at least one Joker, since only four copies of each number, wind, or dragon tile exist)

"Identical" means truly identical — same number and same suit. Three 5 Craks is a pung; a 5 Bam, 5 Crak, and 5 Dot together is not a pung (the card treats mixed-suit patterns differently, and it will say so explicitly).

Where Jokers fit

Jokers can stand in for any tile in a pung, kong, or quint — that's exactly where they live. A quint of a number, wind, or dragon always needs at least one Joker, since only four copies of each of those exist. What Jokers can never do is fill a pair or a single: those must be real tiles.

Calling and exposing a group

If another player discards the tile that completes your pung, kong, or quint, you can call it. Calling has a cost: you must immediately place the completed group face-up on your rack, exposed for everyone to see. That exposure is public information — good players will read it and guess your hand.

You can only call for groups of three or more. You can't call a discard to complete a pair or a single (unless that tile completes your entire hand and you're declaring Mahjong), and you can't call at all while building a hand marked Concealed (C) on the card — except, again, the very tile that completes it for Mahjong.

Why size matters

Bigger groups are harder to complete — a kong needs four identical tiles, a quint five (with Jokers). When you pick a target hand, weigh how many copies of the key tiles you're already holding before you commit.
