What Makes American Mahjong Different?

Unlike Chinese or Riichi Mahjong, American Mahjong:

• Uses Jokers
• Uses an official yearly NMJL card
• Requires matching hands from that card
• Includes the Charleston pre-game exchange

But for now — stay focused here.


The Tiles (152 Total)

American Mahjong uses:

• Dots (1–9)
• Bams (Bamboo 1–9)
• Craks (Characters 1–9)
• Winds (E, S, W, N)
• Dragons (Red, Green, White)
• 8 Jokers
• 8 Flowers

You must use a proper American Mahjong set that includes Jokers.

The NMJL Card (The Most Important Rule)

This is where American Mahjong becomes beginner-friendly.

Instead of building any legal hand, you must complete one of the hands listed on the official National Mahjongg League card.

Each year, the card updates.

It contains:

• 50–60 possible hands
• Organized by categories (13579, Consecutive Runs, Quints, etc.)
• Point values for each hand

Think of it as your roadmap.

Without the card, you cannot play.

The Charleston (Unique to American Mahjong)

Before gameplay begins, players complete the Charleston.

It’s a structured tile-passing phase:

  1. Pass 3 tiles right
  2. Pass 3 tiles left
  3. Pass 3 tiles across
  4. Optional blind passes

The Charleston allows you to:

• Shape your hand early
• Adjust strategy
• Read opponents

Do not treat it casually — it’s strategic.

Joker Rules (Critical for Beginners)

Jokers are powerful — but limited.

✔ Can replace any tile in a pung, kong, or quint
❌ Cannot be used in singles or pairs
✔ Can be swapped if you hold the natural tile

Joker management is one of the biggest skill gaps between beginners and experienced players.

Online platforms enforce Joker rules automatically — which prevents costly mistakes.

How to Win in American Mahjong

You win when:

✔ Your tiles match one exact hand on the NMJL card
✔ All Joker rules are respected
✔ You declare “Mahjong” legally

You can win:

• By self-draw
• By claiming a discard

Scoring is simple — use the card’s printed values.
