Inside a complete set
American mahjong uses more tiles than any other major variant. The extras are what make the game possible: flowers for bonus scoring and eight jokers that act as wild tiles.
A standard American set carries 152 tiles. Three numbered suits make up 108 of them: dots (also called circles), bams (bamboo), and cracks (characters), each running 1 through 9 with four copies of every tile. On top of that come the honor tiles — four winds (East, South, West, North) and three dragons (Red, Green, White) — plus eight flower tiles and eight jokers.
The jokers are the part that surprises players from other variants. They are wild, but only inside groups of three or more, and they may never be passed during the Charleston. Eight of them is the fixed count for an American set; if a set is missing jokers, it is not a complete American set.
Everything else you need to play — the rack and the case — travels with the tiles. The one thing that does not is the card. The National Mah Jongg League publishes a new card every year and sells it on its own; nothing off an old or missing card counts.
152 tiles, fixed
108 suited tiles + 16 winds + 12 dragons + 8 flowers + 8 jokers. A set that claims fewer is missing something you will need.
Engraved faces last
Modern sets are thermoset plastic, melamine, acrylic or bamboo-backed composite. Incised faces stay readable far longer than printed ones.
The card is separate
The annual NMJL card is sold on its own, never in the tile box. Plan to buy the current-year card to play legal hands.

Counts describe the standard American (NMJL) set as commonly sold. Older or house sets may differ slightly.
Tile materials
What the tiles are made of affects how they feel, how loudly they clack, and how long the faces stay readable.
Older American sets were faced with bone or ivory backed by bamboo. Trade in new ivory has been banned under CITES since 1975, so any modern set uses a substitute — and you should be wary of anything sold as "genuine ivory." Today the common materials are thermoset plastics (often described as bakelite-style), melamine, acrylic, and bamboo or resin composites.
The detail that matters most for daily play is the face. Tiles with incised, engraved suits and numbers keep their contrast after years of handling; tiles with only surface printing tend to wear smooth and become hard to read across a table. Weight is a matter of preference — heavier tiles feel solid and shuffle with a satisfying clack, lighter tiles are easier to travel with.
The case, rack and pushers
These are the accessories that turn 152 loose tiles into a playable game.
The case
Most sets ship in a soft zippered case with tile pockets, or occasionally a hard case. A good case keeps the tiles from rattling and the count from drifting.
Rack and pusher
Each player uses a rack — a long tile holder, typically around 19 inches — with a sliding pusher at one end (sometimes called a "betty") to push discards into the center. A four-player game needs four racks.
When you buy a set, check that the number of racks matches the players you expect — four is standard.
What to check before you buy
A short, practical checklist for a complete, playable American set.
The non-negotiables
- 152 tiles, including all 8 jokers and 8 flowers
- Engraved (not just printed) faces with clear suit and number contrast
- Four racks with working pushers, and a case that closes securely
The easy-to-miss bits
- Tile size — larger tiles (around 30 mm / 1.2 in and up) are easier to read
- Whether a current-year NMJL card is included (it usually is not)
- Weight and feel, if you can handle the set first
