The 2026 American Mahjong Card Explained

How is the 2026 card organized?

The 2026 National Mah Jongg League card is the rulebook for American mahjong: it lists every legal winning hand for the year, and a 14-tile hand only wins if it matches one of the card's lines exactly. The card this site uses contains 72 lines, each describing one complete hand, and the matching engine validates every hand against it automatically, so you cannot win with a shape the card does not contain. The game is played with the full 152-tile American set: 108 number tiles, 16 winds, 12 dragons, 8 flowers and 8 jokers. Because the card changes every year, the site's American mode always uses the current 2026 card, and the Charleston and payout rules follow the NMJL standard. It is the same document league players across the country use, so the hands on this site match the official 2026 card exactly rather than a simplified house version.

What sections and point values does the card have?

The card's 72 lines are grouped into nine sections that tell you what kind of hand you are building. The number sections are 2026 (hands built around the year's digits), evens (2-4-6-8), odds (1-3-5-7-9), 369 (the 3-6-9 family) and any-like numbers (matching ranks across suits). The shape sections are quints (five of a kind), consecutive runs (sequences such as 1-2-3-4-5), winds and dragons, and singles and pairs. Point values climb with difficulty: most exposed lines pay 25 or 30 points, quints pay 40-45, and the concealed singles-and-pairs lines pay 50-75. Lines marked concealed must be completed entirely from your own draws (no exposed calls), which is why they carry the highest values on the card. The 2026 lines are built from the year's digits (2, 1 (ones), 2 and 6), and every line totals exactly 14 tiles, which the engine verifies line by line.

How do suit and color constraints work?

Suit and color constraints are the card's grammar, and they are relationships between groups, not fixed suits. Black numbers on the card may be played in any suit, while green numbers must all share one suit and red numbers must all share a second, different suit. The engine treats these as color variables it resolves by enumeration. A hand marked "Any 2 Suits" lets you choose the suits freely as long as two are used. Winds and dragons are fixed tiles with no suit choice. When you match a hand on this site, the engine tries every valid suit assignment and checks the constraint automatically, so a hand that satisfies the rank pattern but violates the color rule is correctly rejected (exactly the check the league applies at the table). In the card data, green and red groups must resolve to different suits, while unmarked groups may take any suit tile by tile; the matcher enumerates every assignment rather than guessing.

Where can jokers be used?

Jokers are the most powerful tiles in the game, with two hard limits. A joker may substitute for any tile inside a combination block of three or more, a pung (three of a kind), kong (four of a kind) or quint (five of a kind). Jokers may never be used in pairs, never for singles, and never on the 2026 or NEWS special tiles, which must be natural. Flowers are different again: they are drawn from the wall, set aside and replaced, and they never count toward a hand on the card. The site's matching engine implements exactly these rules: joker substitution is only allowed where the card line permits it, and special groups are always matched with natural tiles only, so joker-heavy hands still need their core shapes to be real. That matters because jokers change the odds: a hand needing three of a rank becomes realistic once you hold one or two jokers, while pair-dependent hands stay hard no matter how many you hold.

How do you build a hand from the card?

Building a hand from the card is a game of picking one line and steering toward it. Start a game, look at the sections, and choose a line whose required shapes your initial hand already supports (a pair or a pung in the right rank is a strong signal). The easiest wins sit at the top of each section: a single pung or kong of one number plus whatever the card marks as wild for that row. Protect your pair: most American hands hinge on a specific pair such as the 2026 digits, a wind or a dragon, and losing it usually kills the hand. When the Charleston passes leave you pair-rich, aim for a section built around pairs; when they leave you one-rank-rich, quints or kongs become realistic targets. Reading the card early is the real skill (a hand that already holds two of a number or a triplet of a wind has a clear home on the card before the first discard).

How can you practice with the built-in card?

The fastest way to learn the card is to practice matching on the site. Start a game in American mode and let the game highlight your best matching line from the 2026 card (the AI evaluates every line against your current hand, so the suggestion is always grounded in the real card data). Compare your discard choices with the AI's, and use the Charleston to steer your hand toward the line you selected. Ten minutes of focused matching practice beats an hour of casual play, because the skill is pattern recognition: seeing which 14-tile shapes the 72 lines require and recognizing them early in your hand, before the wall thins and your options narrow. The pattern-recognition loop is simple: glance at your 13-tile hand, let the site name your best line, then check what changed after every draw; within a few games the sections themselves will tell you which hands are realistic before the AI does.
