If you are new to Mah Jongg, American Mahjong is the best version to start with. It is structured, social, and built around a yearly rules card from the National Mah Jongg League (NMJL). That makes it easier to learn than many beginners expect.
In this guide, you will learn the basics of American Mahjong in simple English:

What Makes American Mahjong Different?
American Mahjong is not the same as Chinese Mahjong or Japanese Riichi Mahjong. The biggest differences are:
It uses Jokers
It uses an official NMJL card
You must build one of the hands printed on that card
The game starts with a tile-passing phase called the Charleston
That yearly card is what gives American Mahjong its structure. Instead of trying to build any legal hand, you work toward one of the exact hands listed on the current NMJL card.
The Tiles You Need
A standard American Mahjong set includes 152 tiles:
Dots
Bams
Craks
Winds
Dragons
8 Jokers
8 Flowers
If your set does not include Jokers, it is not a proper American Mahjong set.
For beginners, the tile names can feel strange at first, but you only need a little practice before they become second nature.
How the NMJL Card Works
The NMJL card is the most important part of American Mahjong.
Every year, the National Mah Jongg League publishes a new official card with the legal winning hands for that year. Each hand on the card has:
A specific tile pattern
A point value
A category, such as runs, odd numbers, or quints
Your job is to choose a hand that fits your tiles and then build toward it during play.
A good beginner tip is this: do not try to memorize the entire card at once. Learn the layout first, then focus on a few common hands that are easier to recognize during play.
The Charleston
The Charleston is a unique part of American Mahjong and one of the first things beginners need to understand.
Before regular play begins, players pass unwanted tiles in a structured way. The Charleston usually includes:
Passing tiles to the right
Passing tiles to the left
Passing tiles across the table
Optional additional passes, depending on the group
The Charleston matters because it helps you improve your hand before the game really starts. Good players use it strategically, not randomly.
If you are learning American Mahjong rules, the Charleston is one of the best parts to practice early.
Joker Rules
Jokers are powerful in American Mahjong, but they have strict limits.
A Joker can be used to replace a tile in certain groups, such as:
Pungs
Kongs
Quints
But a Joker cannot be used in every situation.
Important rules to remember:
You cannot use a Joker in a single or a pair
A Joker can sometimes be exchanged if you hold the matching natural tile
Managing Jokers well is a major part of playing better
Many beginners make mistakes with Jokers, so this is one of the first things worth learning carefully.
How You Win in American Mahjong
You win when your tiles match one exact hand on the NMJL card and you declare Mahjong legally.
To win, you must:
Match a legal hand from the current card
Follow all Joker rules
Complete the hand correctly
Call Mahjong at the right time
You can win in two common ways:
By drawing the tile yourself
By claiming a discard from another player
In American Mahjong, the score is based on the hand printed on the card, so understanding the card is just as important as understanding the tiles.
A Simple Learning Order for Beginners
If American Mahjong feels overwhelming, learn it in this order:
Learn the tiles
Understand the NMJL card
Learn the Charleston
Study Joker rules
Practice a few basic hands
Play several real games
This order works because it helps you build confidence step by step instead of trying to memorize everything at once.
The Fastest Way to Get Comfortable
The fastest way to learn American Mahjong is to practice real hands after you understand the basics.
A few practice games can help you:
Recognize hands faster
Make fewer Joker mistakes
Feel more confident during the Charleston
Avoid illegal hand declarations
Reading the rules is useful, but actual play is what makes the game click.
