Click in a square to place a white bulb on it: this will turn orange all the squares lined with the bulb, horizontally and vertically, if no black squares are in the way. Your goal is to turn all the white squares into orange, AND keep all bulbs and numbers in white (if you missplace a bulb, bulbs and/or numbers affected will turn red). I'm still learning why red ones appear, and how numbers affect the game. |
