Light Up
Light every square with lamps
Rules
Place lamps on the empty squares so that every empty square is lit. A lamp lights its own square and shines along its row and column until a wall stops it. No lamp may stand in the light of another. A number on a wall says exactly how many lamps touch it from the four sides. Tap to place a lamp, long press to switch to dots — a dot only marks a square where you have decided no lamp goes.
