"Fix" for puzzle addiction

This, plus its cousin, "Mate In 3," is by far the perfect "Fix" for
Any true Chess addiction. When I am doing work and just stuck on something, or waiting for someone, these puzzles are great, they are challenging, as well as numerous. Perhaps the interface could be sharper, or more dynamic, but at $.99, you cant beat it.
I give it 5 thumbs up!
