About this game

A small, fast, genuinely relaxing Sudoku app that never interrupts you, explains your mistakes instead of just flagging them, and never forces an ad in your face.

No forced ads, ever
Every hint, mistake allowance, and Auto-fill run out per puzzle — after that, watching a short ad for more is entirely your choice. Ads never block pausing, resuming, undo, or starting a new game. If you never want to see one, you never have to.

Play at your pace
Unlimited puzzles generated fresh on your device — no bundled puzzle database, no waiting. Easy, Medium, and Hard puzzles are always solvable by pure logic, no guessing required; Expert and Master bring real challenge for experienced solvers.

Mistakes that teach, not just scold
When something's wrong, Simply Sudoku tells you why — whether it breaks a row/column/box rule outright, or is just a dead end for the actual solution — instead of a bare red mark.

Built to feel calm
Light, dark, and sepia themes with system auto-switch. A reduce-motion setting for a stiller experience. Soft, optional sound. No timers or pressure unless you want them.

Helpful when you want it
Pencil marks that auto-update. Unlimited undo. A few free hints per puzzle, and Auto-fill for tidying up the last few forced cells.

See how you compare
Turn on the fully optional, anonymous "Compare my times" setting to see how your solve time stacks up against other players — no account, ever.
