Winter 2023

The Krazydad Discord Community is a new place where you can talk to me, and meet other people who are interested in puzzles. A great place to report problems or mistakes with this website, suggest new features, help me brainstorm and test out new puzzles, get periodic announcements from me, or discuss other deep thoughts. Maybe I'll see you there!

My printable puzzles contain a page of hints in addition to a page of answers.

The hints are puzzle grids that contain numbers showing the order in which the squares were solved by my computer. Although this is not necessarily the order you would solve the puzzle, it's probably in the neighborhood.

Follow the numbered squares in order 1,2,3,4,5... until you find a square you haven't solved yet. This square (or the one or two immediately after it) is a good candidate to solve next.
