Ninekeep.
Classic Sudoku, no gimmicks.
One tap and the grid is there — a clean 9×9, with nothing between you and solving it.
Classic rules, nothing in your way.
Ninekeep gets you to a board you can trust in a tap, then leaves you alone to solve it. No pop-up events, no daily-reward wheels, nothing counting down at you. It's hand-tuned, faithful to the classic rules, and built for iPhone and iPad from the first sketch.
The only number that matters is today's board, which seals the moment you finish it. Solve it whenever you like — nothing expires if you don't.
What's in the app.
- Four difficulty tiers — Easy, Medium, Hard, Expert.
- A daily puzzle that seals into your Ledger the moment you solve it.
- Notes, hints, and a mistake-limit Challenge mode — each one you can turn off.
- Auto-check & conflict highlights — every assist is toggleable, none required.
- Honest stats — streak, best time, sealed count, a Last-30-days mark strip, a 12-week solve-time chart.
- An iPad build that uses the iPad — three-pane shell, dedicated keypad rail, split-pane result.
Cream numerals on an ink board.
Cream serif numerals sit on a dark, quiet board, with a small gilt accent saved for the moments that matter — hint inventory, the daily seal, a current streak. Optional sound and haptic cues keep your placement steady, and both can be silenced completely.
Built to be read by everyone. Dynamic Type from xSmall through AX5, with the layout adapting cleanly end-to-end — including Reduce Motion and Reduce Transparency.
None of the usual traps.
- There's no account to create and no login — and no leaderboards or friends list either.
- Every solving aid is free. You never pay for hints, extra tries, or a forgiven mistake.
- Play fully offline — every puzzle is bundled, so you don't need a connection to solve.
- No limited-time "events" or disappearing challenges built to pull you back in.
