Tough Slitherlink Puzzles (301-400)
20 x 20 Format, Volume 1

Each booklet contains eight big puzzles, with the answers in the back.

Unlike some of my other puzzle series, these books do not get more difficult as the numbers get higher - the difficulty is somewhat random. In each book, the even numbered puzzles (2,4,8 etc.) have symmetrical clues, and are slightly easier to solve, because this often means there are more clues.

These booklets are in PDF format and need the Adobe Acrobat Reader to view or print.

If you like Slitherlink puzzles, you'll probably like my Masyu puzzles, and Galaxy puzzles, both of which also involve spatial reasoning.
