A quiet, native iOS Sudoku for people who care about the puzzle. Hand-tuned difficulty, a human-style solver that explains every step, and zero analytics.
Stuck? The hint isn't a number — it's the technique that uncovers one. The same logic a real solver uses.
Send any puzzle as a Universal Link; both devices play the exact same board, parallel timers.
Editorial typography, paper-and-ink palette, animation only where it earns its cost. Nothing flashes at you.
No analytics. No third-party SDKs. iCloud sync stays inside your Apple ID. Read every word of the policy in under a minute.
The coach names the technique — Hidden Single, Naked Pair, Pointing Triple — and points to where it applies. The discovery stays yours.
A Universal Link contains the puzzle's seed, not its progress. Tap the link, the app opens to the same starting position, and your timer runs alongside hers.
