Light the Pattern

Light the pattern by clicking on the squares. Clicking on a square switches its own state and the state of all squares around it in a + shape. Use the lasers to your advantage - they prevent any squares behind them from switching their state. Choose from 3 difficulty levels - each allowing you to use one less laser (3, 2 and 1 respectively). Create your own levels by using the built-in Level Editor and play them later.
