2024-June 🌻 Happy Summer! 🏖️

Kaleidoscope Logic Puzzles (Summer 2024, Puzzlewright Press) is my first variety slitherlink book, and my most beautiful book to-date. It is spiral-bound, and contains 124 puzzles, including both classic and variety Slitherlink puzzles. These lovely puzles include several unique full-page tessellations that I have not published elsewhere. If you are new to Slitherlink, you'll appreciate the tutorials which cover both classic and non-square-grid Slitherlink puzzles.

Masyu Puzzles by KrazyDad, Volume 1

The finished puzzle will contain a loop made of horizontal/vertical line segments which connect the centers of grid cells.

  • Black circles indicate corners.
  • White circles indicate straights.
  • Black circles must be turned upon, but the loop must travel straight through the next and previous cells in its path.
  • White circles must be traveled straight through, but the loop must turn in the previous and/or next cell in its path.
