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!

Cow and Cactus Puzzles by KrazyDad

Here are hundreds of free Cow & Cactus puzzles suitable for printing.

Cow and Cactus (aka Corral) is a Slitherlink variant invented by David Millar.


Instructions

The goal of this puzzle is to build a fence fully containing all the cows and excluding all the cacti. The fence must be a single closed loop that does not cross itself at any point!

COWS must be kept inside the fence, or they will wander away.

CACTI must be kept outside the fence, as they will give cows indigestion.

CIRCLED NUMBERS are always inside the fence; they indicate visibility. This number counts the total squares visible looking north, south, east, and west from the location of the clue (including the clue's square). You cannot see squares that are beyond the fence.

There is only one solution!


Note: To make the puzzles larger, I have omitted instructions from the puzzle booklets.
