Chow, Pung, Kong, and Pair: What Is the Difference?

Loose tiles become readable when you stop looking at all 13 tiles at once. In standard Hong Kong Mahjong, the basic winning structure is usually four melds and one Pair. Learn the four small shapes below, and the whole rack becomes less intimidating.

The one-line map

• Chow: three consecutive numbers in the same suit.
• Pung: three identical tiles.
• Kong: four identical tiles, declared as one meld.
• Pair: two identical tiles, also called the eyes.

Chow: a three-tile sequence

A Chow is made from three consecutive numbered tiles in one suit: 2–3–4 Bamboo, for example. The numbers must connect and the suit must stay the same.

Winds and Dragons are honor tiles. They have no numeric order, so East–South–West is not a Chow. A mixed-suit run such as 3 Bamboo–4 Dots–5 Characters is not a Chow either.

Pung: three identical tiles

A Pung is three copies of exactly the same tile. It may use numbered tiles, Winds, or Dragons.

The word identical matters. Three Dragons of different colors do not make a Pung. Neither do three Bamboo tiles with different numbers.

Kong: four identical tiles

A Kong is four copies of the same tile. When it is properly declared, it counts as one meld even though it physically contains four tiles.

Because the Kong has an extra tile, the player normally draws a replacement tile after declaring it. The exact declaration and supplement-draw procedure should follow the rules chosen by the table.

Pair: the two-tile anchor

A Pair is two identical tiles. A standard hand needs one Pair alongside its four melds.

A Pair is not a meld. During ordinary play, you do not expose a Pair merely because another player discards its match; a discard may complete the Pair when it completes your legal winning hand, subject to the table’s rules.

How 14 tiles fit together

Think in blocks, not in one long row:

Four three-tile melds plus one two-tile Pair use 14 tiles. A declared Kong still occupies one meld position; its replacement draw keeps the hand’s structure balanced.

Which shape should you keep?

At the beginner stage, first ask what is already complete:

1. Mark every clear Chow, Pung, or Kong.
2. Look for one natural Pair to anchor the hand.
3. Separate incomplete shapes such as 4–5 or two identical tiles.
4. Check whether an honor tile can only become a Pung or Pair.
5. Before calling a discard, ask what shape it completes and what flexibility you lose.

This is shape recognition, not a promise that every structurally complete hand meets your table’s fan minimum.

The mistakes beginners make most often

• Mixing suits inside a Chow.
• Treating different Winds as a sequence.
• Calling four identical tiles a Pung without declaring the Kong correctly.
• Counting the Pair as one of the four melds.
• Forgetting the replacement draw after a declared Kong.
• Completing the shape but not checking the table’s minimum fan requirement.
