Mahjong Variants

Mahjong isn’t one single game—it’s more like a family of games that share the same tiles but differ dramatically in rules, pacing, and strategy depending on where you are in the world. What looks like a familiar setup (144 tiles, 4 players, drawing and discarding) can turn into completely different gameplay philosophies across regions.

​

Here’s a deep dive into how Mahjong is played in different parts of the world, including rules, structure, and unique cultural twists.

  • Sets:

    • Pung (3 identical tiles)

    • Chow (3 sequential tiles in same suit)

    • Kong (4 identical tiles)

    • Players draw and discard tiles in turns.

    • You can claim discarded tiles to complete sets.
