How the American Game Took Shape
New rules, a new league, and a yearly card
- Explain why the American rules needed standardizing
- Identify the founding of the NMJL in 1937
- Name the American twists: jokers, the Charleston, and the card
As the game spread, every group tweaked the rules to their own taste. That was fun — until two groups sat down together and realized they were playing different games.
To end the confusion, a group of dedicated players formed the National Mah Jongg League — the NMJL — in 1937. Their mission: agree on one shared set of rules for the American game.
Arrival
Mah Jongg reaches the U.S. and becomes a social sensation, especially in cities and clubs.
The American version grew its own personality. It added joker tiles (wild cards), the Charleston (a tile-passing ritual at the start of each hand), and — most importantly — an official card of allowed hands that changes every year.
What makes it “American”
Jokers, the Charleston, and the yearly card are the biggest features that separate American Mah Jongg from the Chinese, Japanese, and other Asian versions.
Why was the NMJL founded in 1937?
- Clashing house rules created the need for a standard.
- The NMJL formed in 1937 to unify the American game.
- Jokers, the Charleston, and the yearly card define the American style.
