Activize is a fun and addictive problem solving game. First, you choose the size of the game board, from 5x5 to 13x11, and the difficulty. Then a maze of wires is created, branching out from the power supply ( always in the center ) to the light bulbs Next, the wires, bulbs, and power supply are randomly rotated It's your job to rotate them back in the proper direction so that all the lights turn back on. To help you in your quest, you can "lock" a square. If you think a piece is pointing the right direction, you can "lock" it so you don't accidently turn it. When a square is locked, the background turns blue.
