Mahjong is a tile-based game that originated in China. Mahjong Solitaire uses 144 tiles arranged in a four-layer pattern. A tile is said to be open if it can be moved either left or right without disturbing other tiles. The goal is to match open pairs of identical tiles and remove them from the board, exposing the tiles under them for play. The game is finished when all pairs of tiles have been removed from the board or when there are no exposed pairs remaining.
There are 4 instances of each of the following tiles: the 9 bamboo sticks (1–9), the 9 wheels (1–9), the 9 numbers (1–9), the 4 winds (N, S, E, W) and the 3 dragons (R, G, W). There is 1 instance of each of the 4 seasons, and of the 4 matching flowers.Numbers (1-9)
