Because it runs entirely in a web browser, games can be started quickly across desktop and mobile devices, making it an excellent option for casual play, teaching new players, and connecting with the international Zung Jung community.
Completed in 2026, ZJMJ represents an important community contribution to the growth of the Zung Jung ecosystem by expanding opportunities for players to find games online and experience the ruleset outside of local clubs.

Mahjong World 2
Mahjong World 2 is a mobile mahjong application for Android and iOS that offers a polished single-player experience with AI opponents and support for multiple rulesets, including World Series of Mahjong (Zung Jung). The app features detailed hand analysis, AI discard suggestions, ready-hand assistance, pattern explanations, achievements, leaderboards, and offline play, making it an excellent tool for both learning and practicing the game.
For Zung Jung players, selecting “World Series of Mahjong” enables gameplay based on the Zung Jung scoring system.
