Deducta Sudoku Classic

About

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.
