Spring 2022

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!

Intermediate Hexadecimal Sudoku (0-F), Volume 6

Each booklet contains a collection of eight different puzzles, 1-per-page, with a page of hints and a page of answers in the back. The booklets are ordered by ascending difficulty -- the puzzles in book 100 are much harder than the puzzles in book 1.

These puzzles are in PDF format and can be printed from your browser or the desktop. Problems printing puzzles? Try these work-arounds.
