2024-June 🌻 Happy Summer! 🏖️

Kaleidoscope Logic Puzzles 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. Lots of 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. Enjoy! |

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.
