Important! The center pieces are part of the core and subsequently cannot move relatively to each other. For that reason they are already "solved". The solving process is actually bringing all corner and edge pieces to the "already solved" center pieces (meaning there are only 20 pieces to solve out of the 26). For example, the blue center piece will always be opposite to the green center piece (on a standard color-scheme cube). It doesn't matter how hard you will try scrambling the cube, it will just stay that way.
Even in the manual it states that you will need to practice using trial and error. Personally, we have a feeling that people who like doing puzzles and working things out will enjoy this more. It is important that you have patience when it comes to building the Rubik’s Build It Solve It cube. However, once you get the hang of this you are going to feel pretty smart. And your friends will be really impressed  because it takes a bit of effort to solve one of these cubes. If you would like to read our review on the d-fantix cyclone 3×3 – please click on the link.

The manufacture of the first Rubik's cube prototypes was by hand. During the late 1970s, methods for mass production were developed and continue to be used today. Typically, production is a step by step process that involves injection molding of the pieces, fitting the pieces together, decorating the Rubik's cube, and putting the finished product in packaging.

If there are no more edges left on the top layer, then they are probably either inserted in the right place but flipped, or inserted in the wrong place. To get an edge out of somewhere it shouldn't be, just insert one of the yellow edges into that slot. This should get the edge out and on the top layer, ready for you to use the above instructions to insert correctly. Rubix Build
