Fourth Seat Mahjong

American Mah Jongg, the way a real table plays it.

The Charleston. Calling tiles. Jokers, exposures and real scoring — with your own official card in front of you. Live tables with real people, and bots to fill the empty seats when your fourth doesn't show.

Four ways to play

One app, whether you have three friends or ten quiet minutes.

Four players

The full American game — the Charleston, calling, exposures, jokers and scoring. Empty seats fill with bots, and a chair you leave is held for you.

Solitaire

Nineteen tile-matching layouts, plus a daily board everyone in the parlor plays on the same day.

The Tower

Twenty solitaire boards of rising difficulty on six hearts, with four trophies along the way and a final board you will not see anywhere else.

Daily challenges

One real hand dealt from the same wall for everybody, every day — and a daily solitaire board with its own leaderboard.

A coach that teaches the card

Coaching draws a border around the sets you are building, ranks the lines you are closest to, reads a joker from the tiles you set it beside, and tells you what a call would cost you — then steps aside the moment you tap the badge. Classic mode is just you and the tiles.

Learning the game? Start coached. Been playing for thirty years? Start classic.

The Parlor: chat, open tables and the weekly ladder.

The Parlor is always open

Start a table in a tap and text the link — it opens straight to your seat. Chat runs all day, friends have six-character codes, and the weekly ladder crowns whoever climbs highest. Every shuffle is committed before the deal and revealed after, so a wall can be checked rather than trusted.

Questions people ask first

Do I need the official NMJL card?

For the card's hands, yes — bring your own current card. The app is not affiliated with the National Mah Jongg League and does not include the card, which is copyrighted; cards come from nmjl.org. Thirty original example hands are included and shown in full, so you can play and learn without one.

Can I play on my computer?

Yes. The Parlor runs in any browser — the same account, the same tables and the same friends as your phone, on a full-size screen.

Is it free?

Everything you play on your own is free, always. Online play is free for your first month, then the Parlor Pass is $4.99 a month or $49.99 a year.

What if my fourth doesn't turn up?

Bots take the empty chairs, at the skill level the table's host picks, and hand the seat back when a person arrives.
