New: every solved board now ends with a report showing how much you cracked by pure logic — and where you guessed. Fresh daily puzzles, Easy to Extreme.
Most sudoku apps tell you whether you were right. Deducta tells you why — and whether you actually deduced it or simply got lucky.
WHAT MAKES IT DIFFERENT
Every puzzle you finish ends with a solve report: which techniques you used, how much of the grid you cleared by pure logic, and exactly where you started guessing. Deducta learns which techniques you have mastered and which ones you quietly avoid, then builds boards around your weak spots.
No more grinding through random grids. Every puzzle has a reason to exist.
TRAIN THE TECHNIQUES THAT ACTUALLY MOVE YOU FORWARD
- Naked and hidden singles, pairs and triples
- Pointing pairs and box-line reduction
- X-Wing, Swordfish and XY-Wing
- Unique rectangles and advanced chains
You learn them in context, on a real board, at the exact moment they apply. No wall of theory to memorise first.
FIVE LEVELS, ONE PROMISE
Easy, Medium, Hard, Expert and Extreme. Every board has exactly one solution and can always be finished by logic alone. You will never be forced to guess.
BUILT TO BE COMFORTABLE TO READ
- Large, high-contrast numbers
- Generous tap targets that forgive an unsteady hand
- A clean grid with nothing competing for your attention
- Light and dark themes
CLASSIC SUDOKU, DONE PROPERLY
- Smart notes and automatic candidate cleanup
- Undo, hints and error checking, all under your control
- A new daily puzzle to keep your streak alive
- Statistics that matter: solve times, accuracy and technique mastery over time
Whether you are chasing your first Extreme board or you just want a calm, readable grid with your morning coffee, Deducta meets you where you are.
Train your logic. Stop guessing. See the difference in your own numbers.
