"Nothing changed about how we play. Everything changed about how much we care who wins."

what happens when the season is on the line

How it works

Scoring as easy as 1, 2, 3.

Two points for a mahjong. One for a jokerless hand. One more if it was concealed. Reward whatever your table brags about, and leave out the rest.

Set your rules once

Two points for a mahjong, plus whatever your table rewards. Jokerless hands, concealed hands, back to back wins. Turn on only what you want.

Then just play

Tap who won and tap which bonuses applied. Points are added and the standings update themselves.

Crown a winner

Whoever tops the game night takes the title, and drinks from the good glass next time. Every game night rolls into a season too, so there is always something bigger on the line than tonight.

Prefer to play by the card? Official NMJL scoring is here too, a second mode that uses the values from your own card. Not affiliated with the National Mah Jongg League.

See it in action

Same hand. Different table.

The point values are yours to set. Here's the exact same jokerless, concealed win, scored two different ways, because two different tables decided it should count for two different amounts.

A by-the-book table

Jokerless +1 Concealed +1
2 base + 1 + 1 4 pts

A table that plays it up

Jokerless +3 Concealed +2
2 base + 3 + 2 7 pts

Same win, same night, and neither table is scoring it wrong. Set your own values once in House Rules, and every hand from then on scores exactly that way, automatically.

The season

Two ways to win

One board rewards turning up. The other rewards playing well when you do. Nobody is out of it just because life got busy.

Grand Champion

Most points across the season. Every night you play adds to your total, so showing up counts for something.

Hot Hand

Best average per game night. Miss a few weeks for work or travel and you are still right in the running.

Built for real tables

It knows how you actually play

Because game night is never as tidy as an app expects it to be.

  • One table or three, it doesn't mind
  • Someone shows up late? Add them mid game night
  • Wall game with no winner? That gets logged too
  • Two tables running at once? It asks before counting a back to back win
  • Share the standings to your group chat in one tap

No more scrolling through the group chat

One link tells you who's actually free, before you ever lock in a night.

  • Send one link by text or group chat, to as many nights as you're floating
  • Just tap and it's saved, nothing to download
  • Answers show up live, across every night you're considering
  • Once you pick the date, that same group becomes your RSVP list
Standing game night

Same night every week? Skip the poll.

If your group already has a standing night, you don't need to ask which nights work, you just need to know who's actually coming.

  • One RSVP link for your standing game night, no new poll to send each week
  • Anyone in the group can answer without downloading anything, only the host needs the app
  • In, maybe, or can't make it, answers update live as the group responds
  • Know who's walking through the door before the tiles come out

Questions

The things people ask first.

Is this affiliated with the National Mah Jongg League?

No, it is not affiliated with the League. It does support official NMJL scoring, as one of two modes: pick official and the values come from this year's card, with points moving from payers to winner, or pick casual, the default, where your table sets what a mahjong is worth and which bonuses count. Switch whenever you like.

Does it use the NMJL card values?

It can. In official NMJL mode you enter the value printed on your own card for the winning hand, and the app handles the payments, including who pays double. It does not reproduce the card, its hand names or its values, so you still play from the card you bought.

Can our group make up its own table rules?

Yes, that's the idea. You set what a mahjong is worth and which bonuses count, and every game night is scored that way. Change it whenever your table decides. Still working out what yours should be? There's a guide to American mahjong house rules on this site.

Do I need everyone to download the app?

No. One person keeps score. Everyone else can be added as a player without an account, and anyone who wants to follow along on their own phone can use a free view-only code.

Do you have to play American mahjong for money?

No. Plenty of groups play for points and bragging rights only. The Mahj Report keeps a running score and a season title, so a night still means something without any money on the table.

What is a wall game in American mahjong?

A wall game is a hand where the tiles run out before anyone declares mahjong, so nobody wins it. The Mahj Report logs a wall game as a hand played with no winner, so it counts toward the night without awarding points.

How is American mahjong different from mahjong solitaire?

They're different games that share a name. Mahjong solitaire is the single-player tile-matching puzzle found in app stores and on free game sites. American mahjong is a four-player tile game played around a table, usually with the National Mah Jongg League card. This app is for that one.

Where can I get a printable score sheet in the meantime?

There is a free printable American mahjong score sheet here. One page, six hands, a row for your own house rules, and no email required.

Why are there different spellings for mah jongg?

All of them are in use. The National Mah Jongg League and most American clubs write it as two words with two Gs, mah jongg. Newer brands and most players under fifty write it as one word, mahjong. Mah-jongg, majong and mahjongg turn up too, all pointing to the same family of games.
