How to Play American Mahjong: A Complete Beginner's Guide

What Is American Mahjong?

Mahjong originated in China during the 19th century and arrived in the United States in the 1920s. Over the following decades, American players introduced several unique innovations—most notably Jokers, the Charleston passing phase, and an annual card of required hand patterns published by the National Mah Jongg League (NMJL).

Unlike traditional Asian variants (such as Chinese or Riichi Mahjong), where players can form any combination of four sets and a pair, American Mahjong requires your final 14 tiles to match one specific line on the current year's official NMJL card. Because every table in the nation uses the same card, players can easily gather and play together anywhere in the country.

What Do You Need to Play?

Setting up an American Mahjong table requires standard equipment. Here is what you will find at a typical table:

Understanding American Mahjong Tiles

A standard American Mahjong set contains 152 tiles divided into seven distinct families. You don't need to memorize every single tile before playing, but learning to identify the suit and group makes reading your hand natural.

What Is the American Mahjong Card?

Published every spring by the National Mah Jongg League, the card organizes all valid winning 14-tile hands into distinct categories, such as:

• 2026 / Current Year hands (hands incorporating numbers from the current year)
• 2468 (Evens) and 13579 (Odds)
• 369 and Consecutive Runs
• Winds & Dragons
• Quints (groups of five identical tiles)
• Singles & Pairs (concealed hands requiring no Jokers)

How to Set Up an American Mahjong Game

Setting up the table takes about three minutes. Here is the standard sequence:

1. 1

   Wash the Tiles

   Turn all 152 tiles face down on the table and thoroughly mix ("wash") them with both hands.

2. 2

   Build the Four Walls

   Each player builds a wall in front of their rack that is 19 tiles long and 2 tiles high (38 tiles per wall). Push the four walls together in the center to form a square courtyard.

3. 3

   Roll Dice & Identify East

   Players roll the dice to determine who serves as Dealer (East). East rolls the dice again, counts around the table counterclockwise, and breaks East's wall to begin dealing.

4. 4

   Deal the Tiles

   Tiles are dealt in stacks of 4. Each of the four players receives 13 tiles, except East who takes a 14th tile to take the first turn.

Understanding the Charleston

The Charleston is a unique tile-passing phase conducted before regular play begins. It gives each player an opportunity to pass unwanted tiles and shape their hand toward a viable card pattern.

How a Turn Works

Once the Charleston finishes, regular gameplay begins. East makes the first discard (because East already holds 14 tiles). Play then proceeds counterclockwise.

Calling Tiles and Exposing Hands

When another player discards a tile, you may be able to call it (claim it), even if it isn't your turn!

How Jokers Work

Jokers are wild tiles that add flexibility and excitement to American Mahjong. However, strict rules govern where and how they can be used:

How Do You Win American Mahjong?

You win by being the first player to assemble a complete 14-tile hand that matches one line on the current NMJL card exactly.

How to Practice American Mahjong at Home

You don't need three other players to start building your confidence. Here are practical solo exercises:

• Tile Sorting Drills: Draw 13 random tiles from your bag and practice sorting them into suits and families as quickly as possible.
• Card Matching: Take your 13 tiles and find 2–3 candidate lines on your NMJL card that fit those tiles.
• Solo Charleston Drills: Deal 4 hands of 13 tiles each and practice running through the Charleston sequence by yourself.
