Phil's Sudoku Helper & Solver

This sudoku solver shows how puzzles can be solved using purely logical, "human" techniques. Each technique is accompanied by a help screen which gives full explanation of the logic involved. The underlying code runs fastest in the Chrome browser, and this is highly recommended.
