Slitherlink Nurikabe Pencilbox

If you love the logic puzzles at the back of a puzzle magazine, this one is for you. Pencilbox has eight classic Japanese pencil puzzles: Slitherlink, Nurikabe, Hitori, Masyu, Star Battle, Takuzu (also called Binairo), Tents and Trees, and Futoshiki. Each one has four levels, from easy ones you can finish over a coffee to expert grids that take a while. Every puzzle has exactly one answer, and you can always get there with logic. You never have to guess. When you get stuck, tap the lightbulb. The hint shows you which squares to look at and tells you why the next one has to be what it is, for example "Stars can't touch, not even diagonally, so this square stays empty." You can fill it in yourself or tap Show me. After a few hints you'll start seeing the tricks on your own. Never played one of these before? Each puzzle has a short How to play with a finished example, and we can walk you…
