Sudoku Solver FAQ
How do I set Sudoku Solver as my screensaver on a Mac?
Install SCRNSVRS free from the Mac App Store, select Sudoku Solver in the library and click Set as Screensaver. macOS starts it whenever your Mac is idle, exactly like a built-in screensaver.
Can I use Sudoku Solver as a live wallpaper?
Yes. Click Set as Wallpaper in SCRNSVRS and Sudoku Solver plays on your desktop behind your windows and icons. You can use it as screensaver and wallpaper at the same time.
Is Sudoku Solver free?
Yes. Sudoku Solver is Free Forever in SCRNSVRS – no account, no ads, no subscription.
Is Sudoku Solver a video loop?
No. Sudoku Solver is rendered live on your Mac with Metal, so it never repeats and stays sharp on any display size. The clip on this page is a screen recording of the real thing.
Will Sudoku Solver slow down my Mac or drain the battery?
No. SCRNSVRS drops to 30 fps on battery and stops rendering when the wallpaper is covered by a full-screen app, so Sudoku Solver costs next to nothing in everyday use.
