Mahj!

Play American Mahjong! Rule Guard, artisan tile themes, Academy, and Solitaire. Free, ad-free, built for the parlor table.

Mahj! is a boutique American Mahjong parlor for iPhone — built for players who want rule trust, clear tiles, and a familiar layout.

PLAY VS AI Sit at a full NMJL-style table in one or two taps. Select a tile, then confirm Discard — no drag-and-drop accidents. AI seats fill the other chairs so you can practice alone anytime.

RULE GUARD Illegal moves are blocked in real time. Every reject explains why on parchment — including kuikae (swap-call) and other NMJL gotchas that trip up even experienced players.

FAIR DEALS Every deal shows a Fairness Header (SHA-256 + MD5 wall commitment) so you can trust the shuffle.

TILE THEMES & CLARITY Choose from global tile packs with illustrated faces. Oversized tiles and Arabic numeral corner marks are available for senior-friendly play. Preferences persist across sessions.

ALSO INCLUDED • Academy — short quiz duels on waits and Rule Guard • Solitaire — a secondary clear-the-board lounge (not the main event) • Table settings — numerals, oversized tiles, auto-win, claim visibility, neat or messy discards

FREE & AD-FREE No ads. No tracking SDKs. Free to play.

COMING LATER Play with friends (host, join, parlor video) is planned — not included in this release.
