Sudoku Solver is the complete companion for sudoku enthusiasts — whether you want to crack a tough puzzle, sharpen your technique, or simply understand how each solution was reached. Enter any 9x9 grid by hand, tap Solve, and watch constraint propagation and backtracking work through the board in an instant. Stumped mid-puzzle?
