This program is free for your use, and you are welcome to use the resulting puzzles for anything you like, from recreation, to classroom use, to putting on the cover of a catalog you publish. (If you do something like a publication, I'd be interested in getting a copy. It's happened once before.)

However, operating a web site does take a certain amount of time and money. So if you feel like paying $5 (or even $1) via to defray some of my costs for this website, I'd be grateful. You can make this payment by credit card there as well.
