Featured Puzzle: Slitherlink #4 – Zombie Fort!

The zombies are invading the forest! Fortunately, you’re VERY fast at building walls. Can you keep all the villagers safe from the zombie horde?

• Draw a single closed loop between the trees in the forest, to represent the protective wall.
• All villagers must be inside the wall, and all zombies must remain outside it.
• Numbers indicate how many wall segments surround that cell.
• Wall segments must be orthogonal lines between two trees.
• The wall may not branch or cross itself.
