Sudoku Expert is a clean, offline Sudoku game for players who want to get better - not just fill in grids.
Every puzzle is generated with a guaranteed unique solution and graded by the techniques it actually requires, from simple singles all the way to chains and almost-locked sets. When you are stuck, the hint does not just hand you a number: it names the technique, shows you the cells involved, and explains why the digit belongs there.
WHAT YOU GET
- Five difficulty levels - Easy, Normal, Hard, Expert and Master, each graded by the logic it demands, not by how many clues were removed.
- A daily challenge - the same puzzle for everyone each day, with a streak to keep alive. Works completely offline.
- Hints that teach - 26 solving techniques, each explained in plain language at the moment you need it.
- A step-by-step solver - walk any board forward one deduction at a time and watch the reasoning unfold.
- Sandbox - enter a puzzle from a newspaper or generate your own, check whether it has a unique solution, and play it or solve it.
- Notes, undo, mistake highlighting, and a keypad that dims digits you have already placed nine times.
- Challenge mode - invalid moves are blocked outright, for players who want no safety net.
- Statistics and achievements, all stored on your device.
- Light and dark themes, an accent colour picker, and a high-contrast mode.
PRIVACY
Everything you do stays on your device. There are no accounts and no sign-in. The app contains no advertising and no third-party analytics, and it does not request internet permission at all. That is a deliberate design decision, not a feature waiting to be added.
ALSO ON THE WEB
The same game runs in your browser at sudokuexpert.app - nothing to install.
RETURNING PLAYERS
If you have had Sudoku Expert installed since the original version, welcome back. This release is a complete rewrite, so your old statistics could not be carried over - but the app will recognise how many puzzles you solved back then and award you a Veteran badge for it.
