Best Online American Mahjong Sites Compared (2026)
If you searched for a place to play American Mahjong online, you probably noticed there are more options than expected, and they're surprisingly different from each other. Some are free; some are subscription-based. Some have strong AI; some have weak AI. Some support multiplayer with friends; some are solo-only. Some haven't been updated in years.
This is the honest comparison of where to play American Mahjong online in 2026.
What we evaluate
For each platform, the criteria that matter:
- NMJL rule accuracy. Does the site actually follow the official NMJL ruleset, or does it cut corners? Concealed-only hand restrictions, Joker exchange rules, and Charleston mechanics are common shortcuts.
- Current card support. The NMJL card changes every April 1. Sites that haven't updated to the latest card become less useful over time.
- AI quality. A weak computer opponent makes practice unsatisfying. Strong AI rewards good play and punishes loose play.
- Multiplayer with friends. Real-time play with people you know. Some sites have it, some don't.
- Cost. Free, freemium, or subscription. What you pay should match what you get.
- UX and modernization. Some sites are decades old and look it. Others are modern, clean, and accessible from any device.
