21x21 Galaxy Puzzles by KrazyDad

Each booklet contains a collection of 6 different puzzles, with the answers in the back.

The puzzles in these books get significantly harder as the book numbers go up. If you find the puzzles too easy, go up a few book numbers, until you find a good difficulty level.

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

If you like Galaxy puzzles, you'll probably like these Slitherlink puzzles, which also involve spatial reasoning.
