Technique-first Sudoku learning
Learn Sudoku, don’t just solve it.
Sudoku Coach teaches the reasoning behind each move — from singles to X-Wing — so players can recognize patterns instead of waiting for answers.
Built around technique practice
Most Sudoku apps give you puzzles. Sudoku Coach helps you isolate one technique, see why it works, and practice it repeatedly.
Recognize the pattern
Each lesson starts by showing what to look for before asking for the move.
Understand the elimination
Hints explain why a candidate can be removed or why a number must go in a cell.
Practice in context
Move from reading a technique to practicing it in guided puzzles.
