Pung vs Kong in Mahjong: What's the Difference?

· 5 min read

A pung is three identical tiles, and a kong is four. Same suit, same number, or the same wind or dragon. The only difference between them is the headcount.

Mahjong has a name for every group size, and the names sound more intimidating than the tiles do. Here's the whole ladder, with the one place jokers stop being useful.

What is the difference between a pung and a kong?

A pung is three identical tiles. Three 7 Bams, say, or three Red Dragons. A kong is four identical tiles. Four 7 Bams, which also happens to be every 7 Bam in the set.

That last part matters more than it sounds. There are only four copies of each numbered, wind, and dragon tile, so a kong made entirely of real tiles needs every single one of them. If you can't get all four, a joker can fill in, and we'll get to that.

What are the other group names?

The rest of the ladder goes by how many identical tiles you're holding:

You'll hear pung and kong constantly, pair a lot, and quint now and then. A sextet is rare enough that you can stop worrying about it for your first year. If you're curious about the five-tile group, what a quint is has its own page.

Can a joker be part of a pung or a kong?

Yes. A joker can stand in for a real tile in any group of three or more, so pungs, kongs, and quints all welcome one.

Say you're holding two real 7 Bams and a joker. That's a pung. Add a second joker to a third real tile and you've got a kong with room to spare. The joker does the job of whichever tile is missing.

Pairs and singles are the exception. A joker can never be one of the tiles in a pair or a single, ever. If you need a pair, you need two real, matching tiles. It's the single most useful thing to know about jokers, and our joker rules guide goes through the reasons.

How do you get a pung or a kong?

Two ways. You can collect the tiles yourself from your draws and the Charleston, or you can claim a discard that completes the group.

That second one is called calling, and it comes with a firm rule. A discarded tile can be claimed to complete a pung, a kong, a quint, or a sextet. It can't be claimed for a single or a pair. A discarded joker can never be claimed at all. The full timing rules live in when you can call a discard, and the strategy side lives in when to expose.

What does that look like at a real table?

Say you're after a kong of Green Dragons. You hold two. You watch one get discarded, and now only one real Green Dragon is left in the whole set. Maybe it's in somebody's rack. Maybe it's in the wall.

You've got choices. You can wait and hope that last tile turns up. You can settle for a pung and let a joker fill the fourth spot later if one comes your way. Or you can decide the hand isn't worth the wait. None of those is wrong. They're just different bets, and the count of copies left is what tells you which bet you're making.

Is a kong better than a pung?

It depends on the hand you're building, which is the answer you'll hear about most things in mahjong. Neither one is better on its own. Each is a size that some hands ask for and others don't.

What you can say is that a kong is harder to finish. It needs one more tile than a pung does, and with only four copies in the whole set, every one you've seen discarded is a copy you can't draw. That's why experienced players count as they go. If you want to practice, counting tiles is the habit to start.

Pung and kong quick reference

Now you can say it out loud

The next time somebody at the table says "I need a pung," you'll know she wants three of one tile. If she says kong, she wants four. It's a small thing, and it's one of those words that sounds like a secret handshake until the first time you use it.

Say it a few times at the table. Somebody will be happy you did. If you'd like to see the groups in action, our how to play guide walks through a full game.
