How to play

Every spring the National Mah Jongg League prints one card: a single sheet of winning hands, good for that year and that year only. Sit down at an American mahjong table anywhere in the country and someone slides it across the felt. “This is the card. Learn it.”

That is a tall order on day one. The print is small, the names are unfamiliar, and the only place most of us get to practice is a live table, where three other players are waiting on you. Card Sense is the practice table we built instead.

Where Card Sense came from

It started on our own practice nights. New players could recite the rules back to you — jokers fill gaps, flowers are scenery, a Kong is four of a kind — and then freeze when the card asked for a Quint, because nobody had ever drilled the shapes. So we built the drill we wanted: one named hand at the top of the screen, a rack of the real 152 tiles below it, and a clock that tightens a little as you get better.

Forty-two levels, eight chapters

• Pungs 1–6 — three of a kind, the first hand the card ever asks for.
• Kongs 7–12 — four of a kind, with jokers standing in.
• Quints 13–18 — five of a kind, a hand the card leans on.
• Sextets 19–24 — six of a kind, the biggest single-rank set.
• Consecutive Runs 25–30 — three numbers in a row, one suit.
• Winds 31–34 and Dragons 35–38 — the honor tiles.
• The Mix 39–41 — any named hand, picked at random.
• Card Mastered 42 — seven hands, the fastest clock, everything at once.

How you clear a level

Each level names how many hands you must find, from two to seven, and gives you a clock somewhere between 34 and 48 seconds. Find them all before it hits zero and the level is cleared. You get three stars for a level with no wrong taps, two for one or two mistakes, one otherwise, and the seconds left on the clock turn into points.

Miss the clock and you replay that level. Your score stays where it was and nothing is taken away, so a hard level costs you time, not progress. The level number, the dots beside the clock, and the Finds readout all track where you are.

The hands

• Pung: three identical tiles (+100).
• Kong: four identical (+200).
• Quint: five of a kind (+400).
• Sextet: six of a kind (+600).
• Consecutive Run: three numbers in a row, one suit (+150).
• Wind / Dragon Trio: three of one wind or dragon (+120).

Jokers, flowers, and the clock

Jokers are wild for the multiples, Pung through Sextet: they stand in for the tile you are missing. A run takes no jokers at all. It has to be three real consecutive numbers in one suit, which is exactly how the card treats it. Flowers never form a hand. They are in the rack as noise, and tapping one just reminds you to leave it alone. Every find pushes the clock back up four seconds, so a good streak buys you the time to keep going.

Scoring: where the rush is

• Combos: chain finds without a wrong tap and the multiplier climbs to x5.
• Surge: hit five in a row and the board lights up. Eight and twelve push it further.
• Quick Eye: find a set inside five seconds for a flat +50.
• Stars: 100 a star at the end of a level, plus 20 per hand found.
• Time bonus: every second left on the clock is worth 10.

Why this kind of drill works

Reading the card is a pattern-recognition skill, and pattern recognition is built by repetition, not by explanation. A drill is the right shape for it because it strips the table away: one hand at a time, no opponents, no charleston, no scorekeeper. You see the same shape twenty times in ten minutes, which is more than most people get in a month of weekly games.

The clock matters too. It is set just tight enough to stop you from reading the rack letter by letter, which is the habit that slows new players down. Under a little pressure you start seeing a cluster of three 7s as one object instead of three tiles. That is the thing that transfers.

And every wrong tap answers back. Pick a run with a joker in it and the hint says so, in plain words, right away. You are never left guessing why the game said no.

How we build trainers here

Four rules, and we hold to them on every trainer on this site.

• One screen. Nothing scrolls, on a phone or a laptop. The board measures the space it has left and sizes the tiles to fit, so a 24-tile rack looks the same as a 12-tile one.
• Fast to open. No webfonts, no framework, no account wall. Three plain files and the shared tile art, so the first board is on screen in about the time it takes a page of text to load.
• Ramps, not cliffs. Board size, clock, and the number of look-alike tiles all rise together. Difficulty goes up; it never spikes.
• Teach in order. Pungs, then Kongs, then the bigger sets, then runs, honors, and finally everything mixed. The order a teacher would use.

The tiles are the same original artwork we use across the site, the full standard set of 152 American mahjong tiles. No card data is reproduced here: Card Sense teaches the shapes the card is built from, and your own purchased card stays the authority.

What you take to the table

Ten minutes here and the card stops reading as a wall of small print. When someone at the table says “Quint, any three suits”, you know what you are hunting before you look down, and you know a joker can finish it. That is the whole point. This is not a game you win; it is a drill that makes the real game quieter.

For us it does one more thing: it gives anyone who finds this site a practice table at two in the morning, free, with no sign-up and nothing to install. The school is here to teach the game, and a trainer that anybody can open is the most honest way to do that.

Original, and made here

Card Sense is ours. The tile artwork is drawn for this site, the level plan and the teaching order were written here, and the code is hand-written on our shared game shell — no template, no reskin, no borrowed content. If you see this drill somewhere else, it was copied from us.
