Sudoku Solver - Backtracking Algorithm with Visualization

Sudoku solver visualization using jQuery (backtracking algorithm).

Source code: github.com/jadezdon/Sudoku

How it works

The solver uses a backtracking algorithm to solve any valid Sudoku puzzle:

1. Find the next empty cell
2. Try placing digits 1–9
3. If a digit is valid (doesn't violate Sudoku rules), place it and recurse
4. If no digit works, backtrack and try the next option

The visualization animates each step of this process so you can watch the algorithm work in real time.
