Mahjong in the United States: Why the Card Changes Every April

Four pungs and a pair are worth nothing at an American table if the shape is not printed on this year's card. And the card is replaced every April, with a new list of hands.

Four pungs, a pair, and nothing on the card

You close four pungs and a pair. The hand looks right, the same shape every Chinese guide teaches. Then somebody opens the card and runs a finger down the lines. It isn't there. Zero, and there is no fan to count.

The winning combination doesn't come out of the player's head. It comes off a printed sheet replaced once a year, and every player has a copy in front of them.

The card is the rulebook

The National Mah Jongg League has published the card since 1937. The 2026 edition went into play on April 1, 2026 and runs through March 31, 2027, at about $14 standard and $15 in large print, direct from the League.

A card carries 65 to 75 lines in sections with fixed names: the digits of the year, 2468, 13579, 369, any like numbers, quints, consecutive run, winds and dragons, singles and pairs.

Each line carries two marks. An X allows a group exposed off a discard. A C means concealed, built only from what you draw, with the last tile allowed from a discard.

The value sits at the end of the line, from 25 to 75 points. The card did the math before the game started.

152 tiles, eight jokers, and flowers that aren't bonuses

An American set holds 152 tiles: the standard 144 plus eight jokers. Each player builds a wall 19 tiles long and two high, 38 apiece, and four walls come to exactly 152.

The deal leaves 99 tiles in the wall: thirteen each, plus one extra to East, who discards first.

Flowers are where Chinese players get lost. They are not bonus tiles set aside for points. They stay in the hand and count as ordinary pieces of specific lines on the card.

A joker never fills a pair

A joker stands in for any tile inside a group of three or more. It cannot fill a pair, or stand in for a single tile the card asks for.

Pairs have to come naturally, which makes them the exposed edge of every hand, and that is why singles and pairs pays the most.

Jokers can also be taken back. If one sits in an exposure and you hold the real tile, you swap on your turn: hand over the tile, take the joker. An exposure is intent and liability at once.

The quint that needs a joker

Five identical tiles out of a set that holds four copies sounds impossible, and it is. So nearly every quint needs a joker.

Flowers are the exception. The set has eight of them, so a flower quint can be all natural.

Consecutive Run doesn't mean a run

The section name misleads. There is no chow in the American game, no run of three consecutive tiles in one suit, and no line on the card accepts one.

What consecutive run asks for is something else: consecutive numbers, each as its own pung, in different suits. Ones, twos and threes of characters, of bams, of dots.

With runs gone, a middle tile in a suit loses value and discards get cruder.

Charleston: three passes, and the joker stays home

Before the first discard the table passes tiles in a fixed order. The first Charleston is mandatory: three right, three across, three left.

The second is optional, runs in reverse, and needs all four players to agree. After it comes a courtesy pass of up to three tiles between the two players sitting across.

A joker is never passed, in any pass. And only the last pass of each Charleston can go blind.

The Charleston leaks information. What you shed in the first pass says a lot about the hand you are chasing.

Scoring adds, it doesn't multiply

A 25-point hand won on a discard: the player who threw it pays 50 and the other two pay 25 each. Everybody pays the winner, and the one who fed the tile pays the premium.

Win on your own draw and the payments double. Win without a single joker, where jokers were legal, and they double again.

Singles and pairs is the exception, since jokers were never legal there. No jokerless bonus applies, and the higher printed value already covers the difficulty.

If the wall runs out with no winner, nobody pays.

A dead hand is a rule, not an insult

The wrong number of tiles on your rack, a joker in a pair or a single, calling Mah Jongg on a line that isn't on the card: your hand is over.

You stay in the chair and you still pay the winner, but you don't draw, don't call and don't discard. That penalty is what makes the card binding.

Why the American table ended up like this

The game arrived in the 1920s as a fad and shed it within two years. What kept it alive was not a club or a federation. It was living rooms, community centers and a weekly group, many of them in Jewish neighborhoods of New York.

A table that meets every week needs an agreement more than a referee. The annual card is that agreement: everybody plays the same list and nobody argues about value. The trade is real, because calculation gives way to pattern matching.

The other schools sit in How Mahjong spread around the world. Japan took the opposite road, with a federation and a 1,000-point bet, covered in Mahjong in Japan.

Sitting down at an American table

Buy the current card before you play. No video replaces the sheet in front of you, and an old card turns into dead paper on April 1.

Read every section once, then pick two or three lines that fit how you like to play. Chasing the prettiest hand is how an evening passes with nothing declared.

The exception is a group that won't buy a card yearly. A 144-tile Hong Kong set teaches the same mechanics with no annual fee. When the fourth player is missing, Mahjong Solitaire covers it alone, 112 tiles in 56 pairs, and the Culture index collects the rest.
