Mahjong or mah-jongg (麻將, Mạt Chược) is a tile-based game that was developed in the 19th century in China and has spread throughout the world since the early 20th century. It is commonly played by four players (with some three-player variations found in parts of China, Japan, South Korea and Southeast Asia). The game is played with a set of 144 tiles based on Chinese characters and symbols, although some regional variations may omit some tiles or add unique ones. In most variations, each player begins by receiving 13 tiles. The game and its regional variants are widely played throughout Eastern and South Eastern Asia and have also become popular in Western countries. It has also been suggested that the name came from an evolution of an earlier card game called Madiao from which mahjong tiles were adapted. Most Mandarin-speaking Chinese now call the game 麻將 (májiàng). Its name is similar in other languages, except in Thai, where it is called (phai nok krachok), a calque meaning "sparrow cards.". Mahjong, which also exists in card format, was derived from these types of games during the middle of the 19th century, and continued until the end of 20th century.
