Daily sudoku for Mac, iPad and iPhone
A single hand-graded sudoku every day — gentle on Monday, diabolical by Sunday. Solve it on the day to keep your streak, compare times on the leaderboard, and watch your solve times fall. No ads, no account, no subscription.
How it works
Everyone in the world gets the same grid at midnight, your time.
Pencil marks, undo, logical hints and an optional mistake check — nothing that watches a video.
On-day solves earn bonus points and a streak multiplier. Miss a day and it shows — that's the point.
Features
Gentle on Monday, diabolical by Sunday. Every puzzle has exactly one solution and never needs a guess.
Every hint is the next logical technique, named — not a random reveal.
Arrows, digits, pencil mode, undo. Play a Sunday in the time it takes the kettle to boil.
Your time, your grade, your mistakes — as a 3×3 of squares. Send it. Compare it.
Start on the Mac, finish on the train. Your history lives in your iCloud, not on our servers.
Insights
Every solve is logged. Sudoception charts your solve time by weekday, shows which technique stalls you most, tracks mistakes and hint habits, and places your time against the field. It's the difference between playing sudoku and getting better at it.
Leaderboards
Today's fastest, this month's points, all-time points and longest streak — all through Game Center, so there's no account to make and nothing for us to store. Only on-day solves count on the daily board. Buying Pro never buys a place on it.
No names or counts invented — this fills with real Game Center data.
Cross-device
Built native for macOS, iPadOS and iOS with a single codebase — the Mac version isn't a port and the iPhone version isn't a compromise. Widgets tell you whether today's done; a menu-bar item on the Mac counts down to the next puzzle.
Keyboard-first: arrows, digits, pencil mode, undo.
Widgets show whether today's done.
iCloud sync — start on the Mac, finish on the train.
Pricing
No ads. Ever.
Yours forever. Family Sharing on.
Less than a month of a games subscription — and nothing ever renews.
Pro is a one-off purchase. A future major version may be a separate upgrade — if it is, we'll say so plainly.
Privacy
Sudoception has no account, no analytics and no servers of ours. Your solve history syncs through your own iCloud. Leaderboards go through Apple's Game Center. We can't see your times, your streak, or you.
FAQ
No. Pro lets you play past days for the pleasure of it and for your own stats; it never repairs a streak or posts to the daily board.
If you miss a day, Pro quietly spends one freeze (you get one a month) so your streak survives. It can't cover two days in a row.
They're generated and graded by our own solver and checked to have exactly one solution, solvable by logic alone. Every player gets the same one.
None. No banners, no rewarded video, no “watch an ad for a hint”.
In your iCloud. Delete the app, and it's still yours; export it any time as JSON.
