I noticed that there wasn't any free online sudokusolver which allowed you to enter your own puzzle, and then step by step illustrative solve it. Therefore I've programmed my own sudoku solver, which is free for use. It's java server pages, jsp, so you don't have to download any applet to use the solver.
Give it a try, it could help a lot of you who constantly ask for helps to particular puzzles.
Techniques:
Singles, Naked, Subsets, Interactions, All fish's (sword, jelly, squirm), simple colouring and xy-chains. I'm constantly adding new techniques.
Comments are indeed allowed!
