2024-May 🌷 Happy Spring! 🍀

Hey look! New puzzle varieties:

  • Queens (Star Battle meets Chess)
  • Troix (a new kind of Binox)
  • Split Ends (a distant relative of Binox)
  • Triple Cross (new cross-figure puzzles)
  • Circle 9 (A new addictive puzzle that resembles a Sudoku, but isn't!)

Enjoy!

Super-tough Hexadecimal Sudoku (0-F), Volume 7

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.
