What it does

Sudoku is Sudoku. This one is the classic nine-by-nine grid, plus killer variants, plus a daily challenge. Every puzzle has exactly one solution and no fewer than seventeen given cells. The generator has been audited against the full correctness suite — no malformed puzzles ship.

The app is offline-first. Puzzles are generated on device; your progress is saved locally; no account is required. A mistake counter is on by default and can be turned off in settings. Auto-clear of wrong entries is optional. Hints are available, with a monthly token budget for free players and unlimited hints for Pro.

Pro is optional. Two tiers: a yearly subscription and a one-time lifetime purchase. Pro removes ads and ad-supported friction, includes unlimited hints, and turns off the mistake cap. The Daily Challenge is free for everyone.

We do not make cognitive improvement claims. Sudoku is Sudoku.
