In this game there will be some gears and boxes. The gears may be connected to each other either through their teeth or through belts. The boxes are also connected to the gears through belts. Some gears will have arrows on them, indicating the direction of rotation. As those gears rotate, the connected gears will also rotate, and the boxes will also move up or down. Your job is to figure out whether each of the boxes will move up or down. Be careful, sometimes the arrangement of gears will make them stuck. For example when three gears are connected to each other, then they will be stuck and unable to move. In this case, the boxes connected to them will also not move. If you get one of the boxes wrong, then you lose and the game is over. If you get all the boxes correct, then you can move on to the next level, with more gears and more complex arrangements. The more levels you clear and the faster you do so, the higher your rank.
