Download
megamaster runs on Windows 10 and 11 (64-bit). A licence is tied to the Google account you sign in with; without one the app installs but stays at the sign-in screen.
Installing
- Run the installer. Windows should name the publisher as BITB CASH LTD. If "Windows protected your PC" appears instead (a new certificate can still trigger it), click More info and check that the publisher reads BITB CASH LTD before you run it. If it says Unknown publisher, do not run it, and tell us.
- Accept the licence terms. The app installs for your user only; no admin rights are needed.
- Launch megamaster and sign in with Google using the account your licence is on.
- Follow Getting started: its import step imports your hands in the background, and the solved spots start downloading as it opens.
Updates
You don't come back here for updates. When a newer version is published, the app offers it above the header — Update and restart — and installs it in place. Your database and settings are untouched.
Phone
Your drills also run on your phone at app.megamaster.io, signed in with the same account, once you turn on Send my drills to my phone in Settings › Account › Phone drills.
