The rules of Mahjong are not complicated but they are very precise. Mahjong is a tile-based game that originated in China and is now widely popular in many countries. The objective is to complete a set of tiles that are arranged in a particular pattern. In Estonia, the version of Mahjong is called “Shanghai” and it is played with 136 tiles on a table. The game begins with each player receiving 13 tiles. The tiles are shuffled and the players must arrange them into 4 sets of 3 tiles and a pair. Once the tiles are organized, the players then try to match pairs of tiles by exchanging tiles with each other. If the players are unable to exchange tiles, they must draw a tile from the pool of remaining tiles. The game ends when all pairs have been formed. The winner of the game is the player who is left with the most tiles.
