Why Sudoku Frenzy

Built to be played, not monetized

No banner ads, no interstitials between puzzles, no nagging for a subscription. Just Sudoku.

True offline multiplayer

Battle mode works with no internet connection at all — scan a friend's invite and race on the same puzzle.

100% ad-free

No banners, no interstitials, no interruptions. Nothing to buy to make the ads stop, because there aren't any.

Four difficulty levels

Easy, Medium, Hard, and Expert — every puzzle is freshly generated and fully solvable.

Scan-to-battle invites

Point your camera at a friend's invite code to join their board directly — no network required.

Light & dark themes

A clean, distraction-free board that adapts to your system appearance automatically.

Resume anytime

Close the app mid-puzzle and pick up exactly where you left off, notes and all.

Battle mode

Three steps. No wifi required.
