Monday's Good Deed: Play Crossword/Sudoku Puzzle and Donate to Charity?

I love playing sudoku. I love it even more when I can play sudoku and donate to charity. Unfortunately, I haven't found a site that offers the best of both worlds (playing sudoku and donate to charity FREE). Same for crossword puzzle (even though I suck in playing it). It may be a good idea for you out there to start a website like this. If I overlook any website that meets my expectation here, please contact me.

Play and do good at the same time! The banners above are some sites out there that allow you to play games (in the form of quiz or puzzle) and generate free donation. Have any more suggestion on this type of sites? Email me.
