The Lift: Use the elevators to transport the 3 to the other side.
Clicking on an elevator will make it move the number of spaces and the direction specified by the number on its base. The numbers cycle through 1, 2, -3, -2, -1, -2, 3, 2, 1. If an empty elevator in front of the 3 is adjacent with her elevator, she will be moved forward. However, if an empty elevator behind the 3 is adjacent with her elevator, she will move backward (in the event of elevators being accessible both in front and behind her, the 3 will move forward).
