How to play Classic Mahjong

Classic Mahjong (or Mahjong Solitaire) is a tile-matching game. The goal is simple: find and remove all tiles from the board by matching pairs of identical free tiles.

Basic rules

  • Free tiles: a tile is free when there is no other tile on top of it and at least one side (left or right) is unblocked.
  • Matching pairs: click two free tiles with the same symbol to remove both.
  • Clear the board: the game ends when all tiles are removed.
  • No moves left? use the hint button or reshuffle the board.

Tile types

There are 144 tiles in traditional Mahjong, divided into groups:

  • Characters (Wan): 1 to 9 in Chinese characters
  • Bamboos (Suo): 1 to 9 represented by bamboos
  • Circles (Tong): 1 to 9 represented by circles
  • Winds: North, South, East, West
  • Dragons: Red (Zhong), Green (Fa), White (Bai)
  • Flowers and Seasons: 4 flowers and 4 seasons (matchable with each other)
