I enjoy puzzles, riddles, and other mental challenges. Not all of them are contrived; some we find in Nature or in our history. On this page, I try to offer some of the more intriguing ones I've found. Where I have a solution (and in one case, where I have a problem with the solution), I offer those as well. I hope you enjoy them.
