Instructions: The object is to arrange the faces of the cubes so that if you stacked the cubes, each of the four long sides of the stack would show four different colors. In this representation of the cubes, the four long sides of the stack are made up of the vertical columns of four squares on each cube, not the two side squares. So, in other words, you have to make each of the faces in the vertical columns of four squares a different color on each cube.

To rotate the cubes, click on a face and it will rotate the cube clockwise about that face. To get back to the starting configuration, hit Reset, to get another starting configuration, hit Scramble, and to see the solution hit Answer.
