American Mahjong is a four-player tile game built around an annual card of valid hands. A typical round moves through five stages: set up the table, receive tiles, complete the Charleston, draw and discard in turn, and declare Mah Jongg when your 14 tiles exactly match a hand on the current card.
This visual beginner’s guide explains that full sequence without reproducing any copyrighted hand from the annual card. Use it as an orientation before your first lesson, then follow the current card and the conventions of your teacher or regular group.
What You Need to Play American Mahjong
- Four players. Three-player adaptations exist, but the standard table and Charleston are designed around four seats.
- An American Mahjong tile set. A common standard playing inventory contains 152 tiles. Some retail sets contain additional spare or specialty tiles, so identify any extras before building the walls.
- A current American Mahjong card. Many groups use the annual Standard Hands and Rules Card published by the National Mah Jongg League.
- Four racks. Racks keep each player’s tiles organized; attached pushers can help move the walls without revealing tiles.
- Optional table accessories. A mat can soften sound, protect the table and make tiles easier to gather.

American Mahjong in Seven Steps
1. Identify the Tiles and Set Aside Extras
Before shuffling, make sure everyone knows which tiles are in play. A common 152-tile inventory contains 108 numbered suit tiles, 16 Winds, 12 Dragons, eight Flowers and eight Jokers. A box labeled 160 or 166 may include additional tiles, but the extra mix is not universal.
Learn the tile families in our American Mahjong tile guide. If your set contains more than the inventory your group uses, separate those extras before the walls are built.
2. Choose Seats and Build the Walls
Each player sits at one side of the table and builds a wall of face-down tiles in front of her rack. With 152 tiles divided evenly, each player has 38 tiles and can build a wall 19 tiles long and two tiles high.
One player is East. Groups use different methods to choose the first East and to break the wall, often involving dice. For a first lesson, let an experienced player lead this part so the table follows one consistent method.
3. Deal 14 Tiles to East and 13 to Everyone Else
Tiles are dealt from the broken wall. East begins with 14 tiles; the other players begin with 13. Keep your tile faces hidden from the other players and arrange them on your rack by suit, number and special-tile category.
At this point, open the current annual card and look for several possible lines rather than committing to one hand immediately. A flexible starting plan makes the Charleston easier.
4. Complete the Charleston
The Charleston is the distinctive American Mahjong passing sequence completed before normal turns begin. During the first Charleston, every player passes exactly three tiles to the right, then three across, then three to the left. A second Charleston—left, across, right—happens only if all four players agree.
Jokers are never passed during the Charleston. Blind and courtesy passes have specific timing rules, which we explain in the step-by-step Charleston guide.
5. East Discards and Regular Play Begins
After the Charleston and any courtesy pass, East has 14 tiles and discards one face up into the center. Play then moves to the right, or counterclockwise around the table.
On a normal turn, draw one tile from the wall, evaluate your hand, and discard one tile face up while clearly naming it. After the discard, your concealed tiles and any exposed tiles together should return to the proper hand count. The rhythm is simple:
- Draw one tile. Take the next available tile from the wall.
- Recheck the card. Compare your rack with the complete lines you are considering.
- Keep 14 temporarily. Decide which tile gives your hand the best flexibility.
- Discard and name it. Place one tile face-up in the center and call it clearly.
6. Call a Discard Only When the Rules Allow It
The most recently discarded tile can sometimes be called to complete an allowed exposed group or to complete Mah Jongg. If you claim the discard to make a legal exposure, place the claimed tile on top of your rack with the completed group, then discard one tile. If the discard completes Mah Jongg, declare it, display the complete hand, and do not discard again.
A tile normally cannot be called merely to complete a single or a pair. A discarded Joker cannot be called. Because the exact hand and its C or X designation matter, check the current card before exposing anything. An incorrect exposure can make the hand dead.
7. Declare Mah Jongg With an Exact 14-Tile Hand
You win when your 14 tiles match one complete line on the card exactly: the right numbers or letters, the correct suit relationships, the specified group sizes and the required exposed or concealed status. Say “Mah Jongg,” display the hand, and verify it against the card.
A hand that looks close is not enough. One wrong suit assignment, group size or concealed/exposed condition can invalidate it. Slow down and read the line from left to right before declaring.
How Exposures, Jokers and Concealed Hands Fit Together
An exposure is a group placed face up on top of the rack after calling a discard. A line marked X on many American Mahjong cards may be played with exposures; it does not require you to expose early. A line marked C must remain concealed, subject to the current rules for completing Mah Jongg. Do not expose a group made entirely from self-drawn tiles during ordinary play, and do not draw a replacement tile merely because you hold four matching tiles.
Jokers can substitute only inside eligible groups of three or more identical tiles, such as a Pung, Kong, Quint or Sextet. They cannot represent a single tile or a pair. A visible Joker in an exposure may be exchanged on a player’s turn for the exact natural tile it represents.

Five Beginner Mistakes to Avoid
- Using every tile in a larger retail set. First identify the standard playing inventory and any extras.
- Choosing one hand too early. Keep two or three related options through the early Charleston passes.
- Reading card colors as tile colors. On the card, colors usually describe suit relationships, not the physical color of the artwork.
- Exposing before checking C or X. A premature exposure can eliminate an otherwise promising concealed hand.
- Forgetting to name a discard. Clear calls help every player follow the table and reduce avoidable disputes.
A Simple First-Game Practice Plan
For your first session, do not measure success only by winning. Aim to complete the setup correctly, recognize each tile family, finish the Charleston without a directional error, and follow the draw-discard rhythm. Use a slower pace and let every player finish arranging her rack before moving on.
On the second game, practice keeping two possible card lines open. On the third, add discard calls and Joker exchanges. Learning one layer at a time is usually more comfortable than trying to memorize every exception at once.
Frequently Asked Questions
How many tiles does each player start with?
East starts with 14 tiles and the other three players start with 13. East discards first after the Charleston and any courtesy pass.
Which direction does American Mahjong play move?
Normal play moves counterclockwise, to the player on the right. Charleston passes use their own right-across-left and optional left-across-right sequence.
Do beginners need the current annual card?
Yes, if the group plays a card-based American Mahjong ruleset such as NMJL-style play. The card defines the valid hands for that year and should not be replaced by a generic reference card.
Can you play American Mahjong with a Chinese Mahjong set?
Not always. American play typically needs Jokers, Flowers, readable suit markings and enough tiles for its standard inventory. Confirm the exact contents rather than judging only by appearance.
Where should I check rule changes?
Use the current official card and guidance from the organization or teacher whose rules your group follows. The National Mah Jongg League explains that its Standard Hands and Rules Card changes annually.
