How to read the card: the nine sections
The card changes every year, but the families it is built from do not. Learn the nine sections and you can read any rack, on any year's card.
Why sections, not hands
The card prints roughly fifty hands, and they change every spring. Nobody memorizes them. What experienced players do instead is read a rack by family: evens, odds, consecutive numbers, like numbers, winds and dragons, 369, quints, singles and pairs, and the year hand. Those nine sections have the same shape every year. Once you can tell which family your tiles are drifting toward, you only have to read one short part of the card, and the Charleston turns from guessing into sorting.
Below is every section, with the one thing it demands, how to spot it on a rack, and the trap each one sets. Every example rack is an original teaching arrangement showing the shape, not a hand from any card.
Year Hands
What it demands: A year hand is built from the year's digits, with soaps for zeros, so it wants 2s and soaps rather than a spread of numbers.
How to spot it: Built around the current year's digits, with soaps standing in for zeros. Spot it when you're holding 2s and soaps plus flowers.
Watch out: Soaps do double duty as zeros, so they get scarce fast. If two are already showing on other racks, the year hand you are chasing may already be out of reach.
2468 (Evens)
What it demands: An evens hand uses only 2s, 4s, 6s and 8s for its numbers, so a single odd number tile rules it out.
How to spot it: Only even numbers: 2, 4, 6, 8. Every odd tile in your hand is dead weight for this section.
Watch out: Every odd tile you pick up is dead weight. If half your rack is odd after the Charleston, you are in the wrong section.
Any Like Numbers
What it demands: Like numbers means the same number across different suits, so a rack spread across several numbers is not it.
How to spot it: The same number collected across different suits. Spot it when one number keeps showing up in two or three suits at once.
Watch out: You need the same number across different suits, and only four of each exist. Losing one suit usually means losing the hand, so count what has been discarded before you commit.
Quints
What it demands: Quints need five of a kind, which is impossible without jokers, so this is a joker question before it is a number question.
How to spot it: Needs five of a kind, and only four of each tile exist, so quints are impossible without jokers. Only chase these when you're joker-rich.
Watch out: Five of a kind, when only four of any tile exist. A quint hand is really a joker-count question: without jokers in hand it is not a plan, it is a wish.
Consecutive Run
What it demands: A run needs numbers stepping up in order with no gaps, which always mixes odd and even.
How to spot it: Numbers that step up in order, like 4-5-6-7. The most flexible section on the card because any starting number can work.
Watch out: The most forgiving section on the card, because the run can slide up or down a number while you wait. That flexibility is also the trap: keep sliding and you never actually commit.
13579 (Odds)
What it demands: An odds hand uses only 1s, 3s, 5s, 7s and 9s for its numbers, so a single even number tile rules it out.
How to spot it: Only odd numbers: 1, 3, 5, 7, 9. The mirror image of 2468, usually with more hand choices.
Watch out: The mirror of the evens family, and usually the better bet early: odd tiles include the 1s and 9s that other players throw away without thinking.
Winds & Dragons
What it demands: This section is built mostly from winds and dragons, so a rack full of number tiles is not it.
How to spot it: Built mostly from N, E, W, S and the dragons, sometimes with a few numbers. Spot it when winds keep piling up on your rack.
Watch out: Only sixteen winds and twelve dragons exist in the whole set, so honors dry up quickly. If nobody is discarding them, somebody else is collecting them too.
369
What it demands: 369 uses only 3s, 6s and 9s for its numbers, and it needs the 6 to tell it apart from a pure evens or pure odds hand.
How to spot it: Only 3s, 6s, and 9s. A small, focused family: if you hold several of those three numbers, look here.
Watch out: A narrow family: three numbers across three suits. The upside is that it reads clearly, so you know early whether you are in it. The downside is there is nowhere to slide.
Singles & Pairs
What it demands: Singles and pairs means no pungs or kongs at all, and no jokers anywhere.
How to spot it: No pungs or kongs, just single tiles and pairs. NO JOKERS ALLOWED, which is why these hands pay the most.
Watch out: NO JOKERS, anywhere, ever. That is exactly why these hands pay the most and why you should not start one unless the tiles are already falling your way.
Reading a rack in three questions
- Are the numbers all odd, all even, or mixed? All even points at 2468; all odd at 13579; a mix with a clear step (4-5-6-7) at Consecutive Run.
- Is one number repeating across suits? That is the signature of Any Like Numbers.
- Are the honors piling up? Winds and dragons collecting with few numbers points at Winds and Dragons.
Then count jokers. No jokers and a rack of pairs can be Singles and Pairs, the best-paying section; two or more jokers opens up Quints.
Common questions
Does Mahj Trainer include the NMJL card?
No. The card is copyrighted and changes every year. Mahj Trainer teaches the section structure with original practice hands, so your skills work with whichever card is current. Bring the official card to the table.
Which section is easiest for a beginner?
Consecutive Run is the most forgiving, because the run can slide up or down a number while you wait for tiles. 2468 and 13579 are the easiest to recognize at a glance.
Why does Singles and Pairs pay the most?
Because jokers are never allowed in it. Every tile has to be the real one, and you cannot call discards for pairs, so it is played entirely from your own rack.
What is a year hand?
A hand built from the digits of the current year, with the soap (White Dragon) standing in for any zero. It changes every year by definition.
