American Mahjong Tiles for Beginners: Learn All 152 in One Sitting

American mahjong looks like a lot until you lay the tiles out in groups. Then it turns out there are only 34 designs to learn — most of them printed with the same numbers and letters you already read every day. This guide walks through every tile in the set once, slowly, so that the next time you see a full table, nothing on it is a mystery.

The big picture: 152 tiles, five families

A regulation American set has 152 tiles in play. They fall into five families, and every rule you will ever learn hangs on one of these five:

Notice the arithmetic: 34 designs with four copies each (136), plus 8 unique flowers, plus 8 identical jokers. If you can recognize 34 pictures, you can read the whole set.

The three suits: Craks, Bams and Dots

These work exactly like the suits in a deck of cards, running 1 through 9, four copies of each.

• Craks (characters, 万) — the ones with a Chinese character under a big black numeral. American sets print the Arabic number right on the tile, so a “7 crak” literally says 7. You never need to read Chinese to play.
• Bams (bamboo, 条) — little green bamboo sticks. Count the sticks to get the number — except the 1 bam, which is a bird (a sparrow or peacock, depending on the set). It is the most famous tile in the game and the one everyone remembers.
• Dots (circles, 筒) — round circles, usually blue or multicolored. Count the dots.

Winds and dragons: the honors

sixteen wind tiles carry one letter each — N, E, W, S. Your seat wind matters for some card hands, which is why players keep a wind indicator on the table.

The twelve dragons come in three colors. Red dragons show a red character (中), green dragons a green one (發), and the white dragon — called soap at most tables — is a blank-looking tile or a framed rectangle. On the NMJL card, dragons are matched to suits in some hands, so keep them grouped by color when you sort your rack.

Flowers and jokers: the specials

The eight flower and season tiles are all different — plum, orchid, chrysanthemum, bamboo, spring, summer, autumn, winter, or prettier themed artwork on designer sets. They cannot form pairs or runs. Their only jobs are to sit on the card where a hand specifically asks for them — many hands open with F or FF.

The eight jokers are the wild cards, and they are what makes American mahjong American. A joker can stand in for any tile — but only inside a group of three or more (a pung, kong or quint). A joker can never complete a pair, and it can never be passed during the Charleston. If you remember one rule tonight, make it that one.

A 10-minute drill that actually works

Dump the set on a table and sort it into the five families. Then, within each suit, line the tiles up 1 to 9. Do this twice and your hands will start recognizing tiles before your eyes do. After that, the fastest teacher is repetition with something at stake — our free practice game deals you real hands against three AI opponents, and you can take as long as you want over each one. Pair that with the printable rule card propped next to the keyboard, and the tiles will be old friends within a week.
