Beacon Isles

A calm logic puzzle about lighthouses

Coming soon to iPhone and Android

How it works

Every map is split into islands. Place one beacon on every island so that each row and each column holds exactly one beacon, and no two beacons touch, not even at the corners. Every map has exactly one solution and never needs a guess.
