My suggestion for making better Griddlers.net

Hello everyone. I must say that this is the best site ever for solving griddlers, multigriddlers, triddlers etc. and I think it has everything!
The only thing that I think is missing is some help on every puzzle that exists. What I mean is a hint button when solving a puzzle, or something that can show you some moves you can make if you are stuck. I have find myself many times stuck on a puzzle without knowing what to do next and many times I had to guess and mess up with the puzzle.
Of course there would be a small penalty for using the hint button, such as losing a few points.

What's your opinion?
