Mahjong Hand Finder

Deal a hand or enter your own tiles. The finder ranks every practice hand by how close you are, shows which tiles to keep, and suggests what to pass. It's the skill that makes the Charleston click.

Practice as often as you like. Nothing you do here is shared or sent anywhere.

The hardest moment for a new player comes right after the deal. Thirteen tiles, a card full of hands, and a table waiting for your Charleston pass. Experienced players glance at their rack and see a theme: lots of one suit, a handful of even numbers, a pair of Winds. This tool trains that habit with our own practice hands, so you learn to spot the pattern yourself.

How the hand finder works

For every practice hand, the finder tries every legal way to build it: each choice of suits, every run of numbers where the hand says "any consecutive", every number where it says "any like numbers", and the matching dragon where one is needed. It counts how many of your tiles fit, places your Jokers where the rules allow, and reports how many tiles you still need.

  • Outlined tiles fit the hand you selected. Keep them.
  • Faded tiles don't fit that hand.
  • Pass marks the three tiles that help the fewest practice hands. They are your best Charleston passes or discards.

Jokers are counted the right way

A Joker can stand in for any tile in a group of three or more, never in a single or a pair. So a Joker counts toward a pung of 7 Craks, but it can't finish the pair of Flowers in a hand like this one:

Two suits: the 2s and 4s share one suit, the 6s and 8s share a different suit.

Practice card — not the official card.

That's also why hands made only of singles and pairs, like Pairs Party, are hard: every tile has to be real. Read more in our guide to how Jokers work.

Using it to get better at the Charleston

  1. Press Deal again and, before looking at the results, pick the hand you would go for.
  2. Choose the three tiles you'd pass right.
  3. Compare with the finder. Did you spot the same theme? Did you pass a tile it wanted to keep?

Five minutes of this before your game night makes a real difference. When it feels easy, practice the passes in the Charleston simulator or play a full practice game against three computer players.

Two or three hands at once

Early on, don't commit to a single hand. Keep the two or three closest options in mind, the way the list above shows them, and let the Charleston and the first few draws decide. Tiles that fit more than one of your options are the most valuable ones on your rack.

About the practice card. The finder only knows firstmahj's original practice hands, labeled "practice card — not the official card." At a real game night you'll play from the current card published by the National Mah Jongg League; the same way of thinking applies.

Questions

Frequently asked questions

01 How do I choose which mahjong hand to go for?

Look for the hand that already uses the most of your tiles, especially your pairs, pungs and Jokers. Keep two or three possible hands in mind during the Charleston and narrow down as you get more tiles.

02 Does this tool use the official mahjong card?

No. It only knows firstmahj's own practice hands, clearly labeled as a practice card. The official card belongs to the National Mah Jongg League, so at a real game you match your tiles against that card yourself.

03 What does "4 to go" mean?

It is how many more tiles you need to finish that practice hand, after counting your Jokers wherever they are allowed. A complete hand has 14 tiles, so you win when you reach 0 with 14 tiles.

04 Why are some tiles marked pass?

Those tiles fit none of the closest practice hands, so they are good candidates to pass in the Charleston or discard during play. Jokers are never marked: always keep them.

05 Why can't a Joker finish my pair?

In American mahjong, Jokers may only stand in for tiles in groups of three or more. Singles and pairs must be real tiles, and the finder follows that rule.

06 Can I enter the tiles from my real game?

Yes. Switch to Pick my own and tap the tiles you hold. It is a good way to practice spotting a theme, even though your real game uses the official card.
