Place bulbs and light up every cell on the board. Glowing visuals, numbered wall clues, and three difficulty levels to work through.

Light Up, also known as Akari, is a logic puzzle about lighting the board. You place bulbs that shine down their whole row and column until a wall blocks them, and your goal is to illuminate every white cell. Two bulbs can never see each other, and every numbered wall has to be satisfied exactly.
