How does Gliding Cube™ differ from Rubik’s Cube ®?
With Gliding Cube™, not only can each layer of sub-cubes spin like a Rubik’s Cube®, each individual color tile on the sub-cube can also slide across the face of the cube!  As a result, we get thousands of new color patterns that cannot be created on Rubik’s Cube®!   Not convinced?   Take a look at picture 1, where we simply slide the color tiles on the top layer by one tile position.   This pattern cannot be created by the Rubik’s Cube® because the color tiles on each corner and edge of the Rubik’s Cube® always spin together and can never be separated.   No Rubik’s Cube® algorithms can solve a pattern that allows the tiles on the corners or the edges to go their separate ways!!
 
 

Figure 1. Slide the top layer tiles by one tile position creates a pattern that cannot be created on Rubik’s Cube®

Figure 2. Spin the right and front layer each by 90º, can it be restored by using sliding moves only?

 
And the mystery does not stop here.   We also have to ask the question whether it is possible to create all Rubik’s Cube® patterns by using our sliding moves only.   For example, can we restore the pattern in Picture 2 by sliding moves only? Think about it.  If it turns out that slide moves and Rubik’s® spin moves can create mutually exclusive patterns, a cube that is scrambled with a combination of the two will be extremely hard to solve!   
 
Here are some brain teasers for you to enjoy. 
 
 Problem #1. Spin the 3x3x3 cube twice as indicated in the picture below. Is it possible to restore it using sliding moves only? You can use your own pattern file, or download it from here.    We've got answers already!

If the answer to problem #1 is true, then it is possible to solve any Rubik’s Cube® pattern by sliding tiles only. However, that is only a possibility. We do not know for sure unless someone can answer question #2.
 
 Problem #2. Is it possible to exchange the positions of any two tiles without disturbing the rest of the tiles on a 3x3x3 cube using sliding moves only? If you can do it, please prove it by sending us your solution files.    We've got answers already!
 
The answer to this question will unveil the secret of the gliding cube: Can the gliding cube create all patterns that can possibly be made on the surface of a cube?  In other words, is it true that all patterns on the gliding cube are solvable even if the patterns are created by people manually sticking the tiles on the surface of the cube at random?
 
 Problem #3. Can you solve a 10x10x10 puzzle shown in the picture below? Please note this cube is scrambled with both the traditional spin moves and our newly invented slide moves. This cube puzzle could very well be the most difficult puzzle game in the world. Take a look!    Some one has solved this too!
