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.

Bridges Puzzles by Krazydad

Here are hundreds of free Bridges puzzles suitable for printing. In Japan, Bridges are known as Hashiwokakero (Japanese: 橋をかけろ). They are also known as Hashi or Chopsticks. In these puzzles, you connect the islands to form a network so that you can reach any island from any other island. The number on each island indicates the number of outgoing bridges. You may only connect islands horizontally or vertically, and you may use one or two bridges to connect islands, but no more than two. Each Bridge puzzle has only one unique solution, which you can find without guessing.

The puzzles in these books get progressively harder as the book numbers get higher.

Connect the islands with bridges until each island can be reached from any other island, and each island has as many outgoing bridges as its number. You may only connect islands vertically or horizontally and bridges may not cross. There may be one or two bridges connecting pairs of islands, but no more than two. Each puzzle has a unique solution that can be found without making guesses.
