How to play Mahjong? I played Mah-jong with my friends today. Mahjong is a popular traditional social game in China. Only 4 people can play together. Mahjong are little cubes.In general, the game principles from south and north of China are different. Because there are only 136 numbers of cubes in south side but 152 cubes in north side. That’s all for today. Thanks in advance
