It is nice!
Only two suggestions for a perfect plugin:
1st: If I put it in a post, it doesn't allow me to put it in center. Always goes on left in page.
2nd: It could be a good idea to put a buttom. If you finish the sodoku, push the buttom and... a "congratulations" box opens (or a link to a web is activated).
