Beginner's Guide to American Mahjong: Rules, Tiles & How to Get Started

What Is American Mahjong?

American Mahjong (also spelled Mah Jongg) is a tile-based strategy game played by four players. While it shares roots with Chinese Mahjong, American Mahjong has its own distinct rules, tile set, and scoring system — governed by the National Mah Jongg League (NMJL), founded in 1937.

Today, American Mahjong is one of the most popular social games in the United States, enjoyed by millions of players at kitchen tables, community centers, and clubs across the country.

American Mahjong vs. Chinese Mahjong: What's the Difference?

Many beginners wonder how American Mahjong differs from the Chinese or Japanese versions they may have seen. Here are the key differences:

  • Tile count: American Mahjong uses 166 tiles; Chinese Mahjong uses 144.
  • Joker tiles: American Mahjong includes 8 joker tiles that can substitute for any tile in a hand.
  • Scorecard: American players use an annual NMJL card listing all valid winning hands for that year. The card changes every year.
  • Winning hands: American Mahjong hands are more structured and must match a specific pattern on the NMJL card.
  • Sets are not interchangeable: You cannot use an American Mahjong set to play Chinese (MCR) or Japanese (Riichi) Mahjong.

What's Inside an American Mahjong Set?

A standard American Mahjong set contains 166 tiles, broken down as follows:

  • Suits (108 tiles): Bams (bamboo), Craks (characters), and Dots — each numbered 1–9, with 4 copies of each tile.
  • Winds (16 tiles): East, West, North, South — 4 copies each.
  • Dragons (12 tiles): Red (Chun), Green (Fa), and Soap (Bai Ban) — 4 copies each.
  • Flowers and Seasons (8 tiles): Decorative tiles used in certain hands.
  • Jokers (8 tiles): Wild tiles that can substitute for any tile in a matched set.
  • Blank tiles (6 tiles): Spare tiles used to replace lost or damaged tiles.

Sets also include 4 racks, pushers, dice, and a wind indicator.

What You Need to Start Playing

To play your first game of American Mahjong, you need:

  1. An American Mahjong set — 166 tiles, racks, and accessories.
  2. An NMJL annual card — purchased separately from the National Mah Jongg League website each year.
  3. 4 players — American Mahjong is always played with exactly four players.
  4. A flat playing surface — a standard table works perfectly.

How to Set Up Your First Game

  1. Assign seats and winds. Each player takes a seat corresponding to a wind direction: East, West, North, South. East is the dealer for the first round.
  2. Build the wall. Shuffle all tiles face-down and arrange them into four rows of 19 tiles each, forming a square wall in the center of the table.
  3. Break the wall. The dealer rolls the dice and counts tiles to determine where to break the wall and begin dealing.
  4. Deal the tiles. Each player draws tiles from the wall until they have 13 tiles (the dealer starts with 14).
  5. Play begins. Players take turns drawing and discarding tiles, working toward a complete hand that matches a pattern on the NMJL card.
  6. Call Mahjong! The first player to complete a valid hand calls Mahjong and wins the round.

Understanding the NMJL Card

The NMJL annual card lists all valid winning hands for the current year, organized into categories such as: 2026 number hands, Like Numbers, Consecutive Run, 13579 / 2468, Quints, Winds and Dragons, and Singles and Pairs. Each hand shows which tiles are needed and how many points it is worth. Hands marked with a closed hand symbol cannot use discarded tiles.

Choosing Your First American Mahjong Set

Material: Melamine vs. Acrylic

  • Melamine tiles are durable, have a matte finish, and are the traditional choice. Great for everyday play. Try the Heritage Ivory or Emerald Line.
  • Acrylic tiles have a glossy, premium look and feel. Try the Coastal Mist or Pagoda Sapphire.

Design

USA Mahjong sets feature unique artistic tile backs — from floral patterns to seasonal themes. Popular choices include the Lucky Ladybug for a whimsical look, or the Sakura East Tea House for an elegant aesthetic.

Tips for Beginners

  • Start with the NMJL card. Study the hand categories before your first game.
  • Focus on one hand at a time. Pick one or two target hands at the start of each game.
  • Use jokers wisely. Save them for sets of three or four matching tiles, not pairs.
  • Practice with friends. Playing regularly with the same group helps everyone learn faster.
  • Join a local group or club. Many community centers and libraries host Mahjong groups welcoming to beginners.
