Shanghai Mahjong is a free mahjong game. Woah, its a mahjong game. Woah, take our hand and we'll make it we swear, Shanghai Mahjong is extremely similar to that but in this game, you get to choose what pattern you want the tiles to be arranged in and the arrangements are pretty cool tbh. There are some cool time limits, the ability to re-shuffle, and maybe even hints as to where to look.
