A few years ago I received an email with the question to put a link to a Japanese Puzzle website. As a reward the would sent me a Japanese Puzzle book and they did all the way from Japan to Europe.
As present I received a Japanese puzzle book with Slither Link puzzles. The puzzle book was in Japanese so I had to visit their website to find out the rules and how to solve Slitherlink puzzles.
I really love slitherlink puzzles and are now frequently downloading Nikoli’s slitherlink puzzles as I can’t find Nikoli Slitherlink puzzle books in Belgium shops.
Buy Slitherlink Puzzle Books from Amazon.com. Happy Puzzling!
