==History==
Mahjong as a whole is only a roughly 100 year old game. Originating in China, the game managed to spread across the country, East Asia, and even to the United States during the 1920s. The riichi variant only started emerging in Japan after World War 2. The modern riichi variant played today began in the 1960's, while the addition of red 5's started appearing in the 1980's. It originated as a gambling game, though play for fun or sport are also common.

Mahjong is a zero-sum game - whenever a player gains points, the other players lose a total of that many points. Therefore, [[tile efficiency|developing hands quickly]] and [[defense|minimizing point losses]] are important aspects to the games. Sometimes, it is best to [[betaori|give up winning]] in order to prevent paying for others' hands.

The rules to the game is complex. Gameplay is generally similar to most Asia-originated variants of mahjong. For a more detailed overview, see the [[rules overview]] the page, or the rest of this article.

The game of mahjong itself has numerous variations across the world, including an attempted standardization of "World Mahjong". Virtually every country in East Asia and the United States has a form of mahjong. While they all have the same general principles, they each have very distinct rule variations.

Modern Japanese mahjong sets also come with four [[red five]] dora tiles. One number five character tile, two number five circle tiles, and one number five bamboo tile are replaced with their matching red tiles.
