The best place to play American Mahjong online

mahjo.ng is a free, browser-based American Mahjong game built around the modern American card. Spin up a private table in seconds, share the link, and play real-time games with friends — or fill the empty seats with bots and practise solo. No app, no account, no download.

New to the game? mahjo.ng is a friendly way to learn American Mahjong, too. The engine acts as referee — validating every Charleston pass, exposure, and mahjong declaration — so you can focus on strategy instead of looking up the rules.
