Two sets of colored balls, labeled A through D, sit in a box as shown below. Your job is to move the red balls to the red zone and the blue balls to the blue zone.
Sound difficult? It gets harder. Within each zone, all the balls must stay in their correct ABCD order in order for you to complete the puzzle.
Balls can only move into vacant spots, and they can't jump over other balls.
