I have one .) But it is ugly, can't verify the puzzle, pencils potentials
(after box-line-row reduction) by itself, doesn't allow you to take back
your moves, and is incompatible with parameter format the solver takes.

So it is nothing to be proud of, but it is a nice toy for personal use
when I solve 16x16 sudokus, hand-pencilling got very, very frustrating :)
And it isn't really that hard to write up, try it (if you have spare time
an hour or three).

Those 'hint' and 'solve' would need incorporating some code from solver.
Maybe if this wasn't so ugly... Although I kind of like the way the grid
gets smaller and smaller when candidates lessen.
