These puzzles are starting to become addictive. I think that is a good sign.

Thanks, Bill. Watch for an upcoming announcement of our “free” subscription service: For each puzzle a subscriber solves, he or she will receive a new puzzle by return email. The price of the subscription will be the rating of each puzzle solved as to its difficulty — easy, medium, or hard — plus a report of how much time it took to solve.
