The Krazydad Discord server is a new place where you can talk to me, and meet other people who are interested in puzzles. You can report problems or mistakes with this website, suggest new features or new puzzles, get periodic announcements from me, or discuss the theory-of-puzzles and other deep thoughts. Maybe I'll see you there!

Area 51 Puzzles by KrazyDad, Volume 1

Here are hundreds of free Area 51 puzzles suitable for printing. Area 51 is a Slitherlink variant invented by David Millar. Along with Slitherlink, it also shares rules with Masyu and Corral (which I call Cow and Cactus). The instructions may seem quite complicated if you are unfamiliar with these other puzzles, but it's worth a little perseverance, as the combination of those elements makes for a uniquely satisfying solving experience.

Because there are so many clue types, I have omitted instructions from the puzzle booklets, but fear not: here is a printable page of instructions on how to solve Area 51 puzzles.

Thanks to David Millar, who invented this puzzle format!
