After finding out the Scrabble wasn't available in Canada I figured I'd look for my "game" fix somewhere else. I'd always been a fan of websudoku.com so I pointed my Kindle there only to find the page formatting got totally messed up on the Kindle.
After a bit of digging and trial and error I found that if you use this address it formats it properly:
http://view.websudoku.com/?
Just thought I'd point this out if any other Kindle users wanted a sudoku fix.
