The menu at the top of each page should help you navigate around the site. We'll use the Blog to announce news of any changes and additions as well as any random thoughts, as "the spirit moves us."



Bob Mead (“Uncle Bob”) has been publishing puzzles and popular math and science commentary since 1994. "Aunt Claire" is our tech guru and occasional contributor. You can learn more about us on the About page.


If you are a puzzle person, look for some unconventional challenges. You'll find plentiful word puzzles, math puzzles, hybrids, tutorials, and advice.
If you are a puzzle beginner, dig in and don’t give up. Work with a friend and peek at answers when you need to [Aunt Claire has more suggestions
here]. Anything difficult takes practice, and with practice you’ll become a pro. You'll find current puzzles here and many more at The Bob Store.


We’ve included the best of the past, including some of our regular puzzles, brain teasers, galleries, feature articles, recipes, and some humor. Going forward we plan to keep adding new puzzles, commentary, and whatever else pops into our heads.
