The Krazydad Discord server is a new place where you can talk to me, and meet other people who are interested in puzzles. You can report problems or mistakes with this website, suggest new features or new puzzles, get periodic announcements from me, or discuss the theory-of-puzzles and other deep thoughts. Maybe I'll see you there!
Want to save some trees? Try my Interactive Sudoku, an online version of these puzzles that works on your browser or iPad.
Krazydad Sudokus are also available in a daily puzzle (for print or online).
Here's a blank sudoku grid in case you need to start over.
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.
