Penrose Slitherlink Puzzles by KrazyDad, Volume 1

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

Each book contains an assortment of difficulties, starting with two easy puzzles, then two intermediate, followed by two tough puzzles. If you'd prefer puzzles all of the same difficulty, drop me a note, and I'll send 'em to you.

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.

Finished with Book 100 and want more puzzles? Here ya go!

Also, here are 30 Super Easy Penrose Puzzles, I made for introducing kids to these puzzles. They use a smaller grid so they are not as intimidating.

Feel free to reproduce the puzzles for personal, church, or school use. If you would like to purchase new puzzles for publication, contact me at dad@krazydad.com.
