If you're new to American Mah Jongg, the hardest part isn't learning the rules — it's remembering them mid-game when three other players are waiting on you. Did the Charleston go right first or left? Can a joker complete a pair? Does the discarder pay double? This one-page printable cheat sheet answers all of that at a glance. Print it, set it beside your tile set, and stop scrolling on your phone between turns.

What's covered
The cheat sheet is designed for the moments mid-game when you blank out. Every section is the kind of thing that takes new players a dozen rounds to internalize — laid out so you can glance and keep playing.
The tile breakdown (166 total)
Exactly how many of each tile are in a complete American set: 36 each of dots, bams, and craks; 16 winds; 12 dragons; 8 flowers; 8 jokers; plus a few blank spares. This matters more than beginners realize — knowing there are only 4 of any given number tells you exactly how many are still live.
Group types
Pair (2), pung (3), kong (4), quint (5). Drilled into your head once, never confused again.
The Charleston (R-O-L-L-O-R)
The full passing sequence in a single visual. First Charleston (mandatory) in green, second Charleston (optional, all must agree) in red. With the blind pass and courtesy pass rules noted underneath.
Joker rules — the essentials
Where jokers are allowed (pungs, kongs, quints), where they're never allowed (singles, pairs, the Charleston, jokerless hands), and how to swap your real tile for an exposed joker on an opponent's rack.
Scoring & payouts
The three most common payout conditions in one compact table: won off a discard, self-picked from the wall, and the jokerless bonus. Confirm your table's house rules, but these are the near-universal defaults.
Each turn
The fundamental loop: draw, discard, listen for calls. Five bullets that cover what every player should be doing every single turn.
How to use it
- Print it. A4 or US Letter paper, single-sided, color if you have it (the color-coding helps).
- Laminate or sleeve it. Tile dust and spilled tea are real. A clear sleeve will save you a reprint.
- Keep it beside the table — not on your phone. Phones are a distraction; a single page is a glance.
- Share copies with the other new players at your table. The PDF is free to redistribute.
Frequently asked questions
Is it really free?
Yes. No email signup, no paywall, no watermark. Just click the button and the PDF downloads. If you find it useful, sharing it with another new player is the best thank-you.
Does it include the NMJL card?
No. The annual card is copyrighted and only sold by the NMJL directly. This cheat sheet covers the surrounding rules — tiles, Charleston, jokers, scoring, turn order — so it complements the card.
What size paper should I print on?
A4 or US Letter, single page, color if you can. The PDF is sized for A4 but will print correctly on US Letter with default printer settings.
Can I share it with my mahjong group?
Absolutely. Print as many as you want and pass them around — it's released for free to help more new players get into the game.
What if I find an error?
