Daves Card Puzzle is just one level and is one tough puzzle. The object is just to get all touching cards to match. It's only one level so we didn't include a save feature. The puzzle is optimized for a 1024 x 768 display. If this is too large for your settings, we included a version for a 800 x 600 display. (Will use circles instead of cards) You will need all of your concentration for this one.
