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/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, and hybrids.


If you are a puzzle beginner, dig in and don’t give up. Anything difficult takes practice, and with practice you’ll become a pro. There are many puzzles to practice with, both archived and at The Bob Store.

This new site performs functions both archival and blogal (watch out – we tend to be inventive). We’ve chosen the best of the past, including some of our regular puzzles, brain teasers, galleries, feature articles, recipes, and some humor. We do not avoid the spheres of visual art and music. Going forward we plan to keep adding new puzzles, commentary, and whatever else pops into our heads. The site is a work in progress. Stay tuned!
