American Mahjong Rules for Beginners: A Complete Guide (2026)

If you have ever watched a Mahjong game and thought, “I have no idea what’s happening” — you are not alone. American Mahjong can look complicated at first, but once you understand the basics, it is one of the most fun, social, and addictive games you will ever play. This guide walks you through everything you need to know to go from complete beginner to confident player.

1. What Is American Mahjong?

American Mahjong is a tile-based strategy game played by four players. It evolved from Chinese Mahjong, which has been played for centuries, but the American version has its own distinct rules, tile sets, and culture. In the United States, it is governed each year by the National Mah Jongg League (NMJL), a non-profit organization that publishes an annual card listing all valid winning hands.

The game has exploded in popularity in recent years — especially among women aged 30–60 — thanks to its combination of strategy, social connection, and just the right amount of luck. Mahjong clubs meet in homes, country clubs, community centers, and coffee shops across the country.

American Mahjong is different from the solitaire Mahjong game you may have played on your phone or computer. That is a single-player matching game. The real game — the one in this guide — is played with four people, a physical tile set, and the annual NMJL card.

2. What You Need to Play

• A standard American Mahjong set — 166 tiles, plus racks and pushers
• 4 players
• The 2026 NMJL card — one per player; updated every year and sold separately
• A flat table large enough for four players to each build a wall of tiles

3. Understanding Your Tiles

A standard American Mahjong set contains 166 tiles across several categories. Getting familiar with the tiles is your first step — once you know what you are looking at, the game starts to make much more sense.

The Three Suits (Numbered Tiles)

These are the workhorses of the game — most winning hands are built primarily from suit tiles.

• Dots (Circles): Tiles numbered 1–9 featuring circle patterns. 4 of each number = 36 tiles total.
• Bams (Bamboo): Tiles numbered 1–9 featuring bamboo stalk designs. 4 of each number = 36 tiles total.
• Craks (Characters): Tiles numbered 1–9 featuring Chinese characters with a red number. 4 of each number = 36 tiles total.

Honor Tiles

• Winds: East, South, West, and North. 4 of each = 16 tiles total.
• Dragons: Red Dragon, Green Dragon, and Soap (White/Blank Dragon). 4 of each = 12 tiles total.

Flowers

Flower tiles are numbered and often feature decorative designs. There are 16 Flower tiles in a standard American Mahjong set. Flowers frequently appear in NMJL card hands and are an important part of the game.

Jokers

Jokers are unique to American Mahjong — they do not exist in Chinese Mahjong. There are 8 Jokers in a standard set. A Joker can substitute for any tile in a group of 3 or more identical tiles. They cannot be used in pairs, and they cannot be used in hands marked “singles and pairs” on the NMJL card.

Jokers can also be exchanged during play — if an opponent has a Joker sitting in a called group on their rack, you can swap it for the real tile it is replacing and take the Joker for yourself. This is a key strategic move.

Blank Spare Tiles

Most sets include 4 Blank tiles as spares — used as replacements if a tile is ever lost or damaged. They are not part of regular gameplay.

4. Setting Up the Game

Before the first tile is drawn, there is a specific setup process:

1. Choose the East player (dealer). Roll the dice — the player with the highest roll becomes East and the first dealer. East also gets an extra tile.
2. Shuffle all 166 tiles face-down in the center of the table. Everyone pushes the tiles around to mix them thoroughly.
3. Build the walls. Each player pushes tiles into a row in front of them — two tiles high and 19 tiles across. The four walls form a square in the center of the table.
4. East rolls the dice again to determine where to break the wall and begin dealing.
5. Deal the tiles. East takes 2 stacks (4 tiles) at a time, going around the table three times. After three rounds, each player has 12 tiles. Then each player takes one more tile, and East takes one additional tile — giving East 14 tiles and everyone else 13.
6. Sort your tiles on your rack. You are now ready for the Charleston.

5. The Charleston

The Charleston is one of the most distinctive features of American Mahjong — it does not exist in any other version of the game. Before play begins, players pass tiles in a structured sequence to help everyone build toward a winning hand.

First Charleston (Required)

1. Pass left: Each player passes 3 tiles face-down to the player on their left, simultaneously.
2. Pass across: Each player passes 3 tiles face-down to the player directly across, simultaneously.
3. Pass right: Each player passes 3 tiles face-down to the player on their right, simultaneously.

Second Charleston (Optional)

After the First Charleston, players may do a Second Charleston:

1. Pass right: 3 tiles to the right.
2. Pass across: 3 tiles across.
3. Pass left: 3 tiles to the left.

Any player can stop the Second Charleston before it starts by saying “no second.”

Courtesy Pass (Optional)

After the Charleston(s), players may offer a Courtesy Pass — an optional exchange of 1 to 3 tiles with the player directly across. Both players agree on how many and pass simultaneously.

6. How to Play

After the Charleston, gameplay begins with East (the dealer) and moves counterclockwise.

On your turn:

1. Draw a tile from the wall.
2. Decide whether to keep it or discard it.
3. Discard one tile face-up in the center of the table, announcing what it is (e.g., “Four Bam”).

Your goal is to build one of the winning hands listed on the NMJL card. You need exactly the right tiles in the right configuration to win.

The round ends when a player calls “Mah Jongg!” — meaning they have completed a winning hand — or when the wall runs out of tiles (a “wall game,” where no one wins and no money changes hands).

7. Understanding the NMJL Card

The NMJL card is the heart of American Mahjong. It lists every valid winning hand for the year and changes annually — you need the current 2026 version.

Each hand on the card shows:

• The tiles required — listed using abbreviations (D for Dots, B for Bams, C for Craks, N/S/E/W for Winds, F for Flowers, etc.)
• Open or Closed: A hand marked with a circle (○) is open — you can call a discarded tile to complete it. A hand marked with an X is closed — every tile must come from the wall.
• Point value: How much the hand is worth, ranging from 25 to 75 points.

Beginner tip: Do not try to learn every hand on the card at once. Pick 2 or 3 hands that look achievable after your Charleston and focus on those for the round.

8. Calling Tiles

In American Mahjong, you can only call a discarded tile for one reason: to complete your winning hand (Mah Jongg). This is different from Chinese Mahjong, where you can call tiles to build exposed melds during the game.

When a player discards the tile you need to win:

1. Say “Mah Jongg!” clearly and promptly — before the next player draws.
2. Place the called tile with your winning hand and reveal all your tiles face-up on the rack.
3. The round ends and scoring begins.

Important: If you call “Mah Jongg” and your hand is not a valid winning hand on the NMJL card, it is a false Mah Jongg. You owe each player a penalty payment and sit out the rest of the round.

Joker exchanges: If an opponent has a called group on their rack with a Joker in it, you can swap the Joker for the real tile it is replacing — and keep the Joker for yourself. This is an important strategic move worth learning early.

9. How Scoring Works

Each winning hand on the NMJL card has a point value — typically 25, 30, 35, 40, 50, or 75 points. When a player wins, the other players pay them based on the value of the hand.

• Win on a discard: Only the player who discarded the winning tile pays — and they pay double the hand value.
• Win on a self-draw (wall tile): All three other players each pay the winner the full hand value.
• Wall game (no winner): No money changes hands. Reshuffle and start again.
• False Mah Jongg penalty: The player who declared incorrectly pays each other player a set penalty amount.

Most casual groups play for small amounts per point — the exact stakes are entirely up to your group. Many beginners play for pennies per point or simply keep score on paper.

10. Common Mistakes Beginners Make

• Forgetting the Charleston direction. First Charleston goes left → across → right. Second goes right → across → left. Easy to mix up — ask your group if you are unsure.
• Calling a tile too late. Once the next player has drawn from the wall, you have missed your chance. You must call before the next player draws.
• Using Jokers in pairs or singles hands. Jokers can only substitute in groups of 3 or more identical tiles. Hands marked “singles and pairs” on the NMJL card do not allow Jokers at all.
• Using last year's NMJL card. The hands change every year. Always use the current card — the 2026 card is what your group should be playing with right now.
• Exposing tiles during the Charleston. Tiles passed in the Charleston should stay face-down until everyone passes simultaneously.
• Declaring a false Mah Jongg. Always double-check your hand against the NMJL card before calling — especially with closed hands. A false call has a real cost.
• Holding too many suits. Beginners often try to keep options open by holding tiles from all three suits. Narrow your focus after the Charleston — pick a direction and commit.

11. Tips for Learning Faster

• Study the card before your first game. You do not need to memorize it — just scan it and find 2–3 hands that look manageable. Go in with a plan.
• Play with patient people. Your first several games will be slower. Find a group who is happy to answer questions.
• Use a Mahjong app to practice. Apps like Mahjong Time let you play hands and get familiar with tile patterns without the pressure of a live game.
• Keep a printed reference sheet at the table. Grab our Free Printable American Mahjong Rules PDF and keep it face-up during your first few games.
• Watch what the winner had. Seeing a completed hand in real life helps you understand the card much faster than reading it alone.
• Do not stress the wall game. Sometimes no one wins and that is fine. Use it as a chance to think about what you were building and what you would change.

Ready to Play?

American Mahjong is one of those games that rewards patience. Your first few games will feel overwhelming — that is completely normal. Focus on learning one section of the card at a time, and before long you will be calling Mah Jongg with confidence.
