2024-September 🍁 Happy Autumn! 🍂
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!Challenging Sudoku Puzzles, Volume 1
