American mahjong is a social, four-player game of strategy played with a specific set of tiles and an annually updated scorecard, distinct from the single-player matching app found on phones. While it shares roots with traditional Chinese games, the American version managed by the National Mah Jongg League (NMJL) is a unique, fast-paced variant defined by the use of wild-card jokers and a mandatory tile-passing ritual known as the Charleston.
Understanding the American Mahjong Difference
Many newcomers confuse the four-player game of mahjong with "mahjong solitaire," the digital tile-matching app. In reality, mahjong is a social game of skill, involving four players who draw and discard tiles to complete specific patterns.
Unlike traditional Chinese or Hong Kong mahjong, where you build hands based on sets of three or four tiles, American mahjong requires players to match specific, pre-determined hand combinations printed on the official NMJL card.

The Charleston: A Mandatory Tile-Passing Ritual
At the start of every American mahjong game, players participate in the Charleston, a unique ritual where tiles are passed to neighbors to help refine hands. This phase is divided into two rounds of passing, followed by an optional "courtesy pass."
- First Round: Each player passes three tiles to the right, then across to the person opposite, and finally to the left.
- Second Round: The process repeats in the same order (right, across, left).
- Courtesy Pass: After the two rounds, players may agree to pass 0, 1, 2, or 3 tiles with the person sitting across from them.
This ritual is specific to the American variant. It allows you to shed unwanted tiles and move closer to the specific hand you have chosen from the card.
Mastering Joker Strategy
Jokers are the "wild cards" of American mahjong, and managing them is a key skill for any beginner. A joker can be used as a substitute for any tile in a pung (a set of three identical tiles), a kong (a set of four identical tiles), or a quint (a set of five identical tiles).
- You cannot use a joker in a pair.
- Exchanging Jokers: If an opponent has previously exposed a set that includes a joker, you may swap that joker for the actual tile it represents during your turn. You must then place the real tile into the exposed set and take the joker into your own hand.
- Strategic Timing: Hold onto your jokers until you are close to finishing your hand, as they are the most valuable resource for completing difficult combinations.

Essential Table Etiquette for Beginners
Mahjong is a social game, and proper etiquette keeps the atmosphere friendly. Always keep your rack organized so your tiles are visible to you but hidden from others. When you discard a tile, announce it clearly so all players can follow the flow of the game. If you are new to the local scene, consider joining mahjong-clubs to practice these social cues in a supportive environment.
How to Get Started Successfully
To begin your journey, you must first acquire the official NMJL card, which is updated every spring. This card is the "bible" of the game—if a hand isn't on the card, it isn't a winning hand.

Frequently asked questions
Can I play American mahjong alone?
No, American mahjong is strictly a four-player social game. The "mahjong solitaire" apps found on mobile devices are single-player puzzles that use the same tiles but have entirely different rules. To play the real game, you need three other players to form a table.
What is the most important item for an American player?
The most important item is the current year's NMJL card. Because American mahjong requires players to match specific patterns printed on this card, you cannot play a legal game without one. The card is updated annually, so ensure you are using the most recent version.
Do I need to memorize the whole card?
No, you do not need to memorize the card. It is perfectly acceptable—and expected—to keep your card on the table in front of you throughout the entire game. Beginners should focus on identifying one or two promising hands early in the Charleston and building toward those.
Why is the Charleston so confusing?
The Charleston is a unique ritual that takes practice. It is essentially a "weeding out" phase where you pass tiles you don't need to your neighbors. Focus on passing tiles that don't fit the hand you have chosen from your card, and don't worry if you don't get the perfect tiles back.
