Hi, I’m Sean, founder of JONGG.
JONGG is a full American mahjong game, and full gameplay is free. Play with friends or standard bots in your browser. You do not need a Membership, subscription or paid trial to play.
Start a game: https://jongg.app/play
We also built short learning exercises, a printable teacher practice packet and game-night planning tools. “Meet the suits” is one small learning exercise, separate from full gameplay. Hosts use a free account, and invitation guests can RSVP by name in a browser without creating an account or downloading an app. The teacher packet does not report exercise results to a teacher.
Optional JONGG Membership adds advanced features. Optional digital tile sets are paid extras; neither is required for the free game.
Bring your own supported printed 2026 NMJL card. JONGG does not include a complete digital card and is independent of the National Mah Jongg League.

I’d love feedback on the full game and what would make JONGG more useful for your table.
