Mahjong is a game played with tiles for 3 or 4 people. A 4 sided wall is built with all the tiles, then each player is dealt 13 tiles, apart from the dealer who has 14. The dealer starts the game by discarding a tile, from then on you each pick the next tile in the wall or the previous person's discarded tile, and then discard one yourself.  You are aiming to get sets of 3 or 4 tiles. There are numerous different hands, which are listed. It sounds more complicated than it is. Come and give it a try. We have lots of sets and lists of what the hands are and instructions how to play. But it is not the game on the internet which is just a simple matching game.
