Get it on Google Play Play in the browser
Mulatschak is available as an Android app on Google Play and as a web app in your browser. Both work offline against the computer.
Install it once; future updates arrive automatically.
If the app is unavailable in your country, the web app works everywhere.
Mulatschak is not in the App Store — the web app is the way onto an iPhone, and it needs neither the App Store nor an account:
Safari: Share → Add to Home Screen.
Mulatschak then opens from your home screen, full screen and offline — against the computer it needs no connection at all.
Chrome, Brave: menu ⋮ → Install app / Add to Home screen. The same works on a desktop.
Nothing leaves your device when you play against the computer. Online play sends the nickname you enter, the room code and your moves. Full details are in the privacy policy.
