Figure out the color of the surface by studying the see-through version (Instructions Below) Instructions Here you can see the surface of a cube in its "unfolded" form (called a net of a cube) and also its "folded into a cube" form. Now in our case the big cube is also made of 27 smaller glass cubes (3 rows, 3 columns, 3 deep), which are either clear or blue. And as you look through the cube, you can tell the colors of the 3 small cubes behind like this: • Darkest is 3 Blues • Next is 2 Blues, 1 Clear • Then 1 Blue, 2 Clears • Lastly 3 Clears Your job is to correctly identify the color of the square on the surface. Use the "Clue" button to reveal one square. You can continue to press the "Clue" button until you solve the puzzle, but that isn't a challenge is it?
