This is a great tool for someone who is learning sudoku - I have a couple of feature suggestions:
1. A way to "bookmark" a puzzle at a certain point where you are confident in your logic, and undo to that point (perhaps with a color change for 'solved' squares - to distinguish them from new work).
2. A way to "remove" a number from the 'suggestion' grid for a single square (for instance, I know a 5 cannot be a choice in a certain square, but I have not placed… the 5 in that square's row or column or box yet, I just want to hide it from my view while I am strategizing).
Thanks again for the lovely looking and handy teaching toolMore

Works beautifully. Not sure that it doesn't defeat the purpose of the game, but then that is better than the game defeating me.

Checkout <a href="http://www.printsudoku.com">Printsudoku.com</a>. It's a new website where you can find lots of sudokus in pdf format, and also you can play online. There is also Magic Sudokus. This site rocks!

Put confirmation on the clear button. I accidentally clicked too close to it while working a puzzle and it got zapped. Thanks.
