Sudoku Mori

Calm daily sudoku with hints that teach. No ads.

What is Sudoku Mori?

Sudoku Mori is a calm daily sudoku for iPhone, iPad and iPhone Duo, made by one developer. There are three new puzzles every day: Valley, Ridge and Summit. When you get stuck, a hint first shows where to look and then explains why the number fits, instead of filling it in for you. Short lessons teach real techniques, up to X-Wing. Each daily you solve grows that day's tree in a small forest. No ads, no account, no analytics, works offline. The dailies are free; a one-time purchase unlocks the harder levels, past dailies and the rest of the lessons. Out on the App Store on 1 December 2026.
