Odds are good that at some point you’ve played a game of Mahjong Solitaire, the game where you remove accessible pairs of matching tiles until (hopefully) none are left. It’s played with a standard set of Mahjong tiles, but beyond that, has absolutely nothing to do with Mahjong.
As Always, Good Luck and Have Fun.
As far as gameplay is concerned, this game is far more similar to Gin Rummy. Your objective is to build melds out of your 13-tile hand—either runs of adjacent ranks in one suit or multiples of a single card. Unlike Gin, if you win the hand, your final hand includes the card you drew, so it contains 14 tiles. Runs, called “chii”, must be 3 tiles long, but sets can have 2, 3, or 4 tiles. A 2-tile set is a special non-meld called the “toitsu” or “eyes”, and you need exactly one to win the hand. A 3-tile set is called a “pon”. A 4-tile selt is called a “kan”, and you draw an extra tile as soon as you form one. This means that the four melds you make could potentially contain 16 tiles, for a final hand size of 18.
