There are 5 different positions your cube can be in now, one of which could be solved. The rest of them have all four corners solved, so do the required amount of U moves so that every corner is in its right place. 2 of the 4 remaining possibilities have a solved bar (as mentioned above, where all three colours on that side are the same), and the other 2 have no solved bars.
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.
Even in the book, during the first step, you’re told that you will need to practice and trial by error. Personally, we feel that this cube will be more fun for children and adults that enjoy puzzles and don’t mind the complications behind a Rubik’s Cube. You must have patience when it comes to building and practicing. However, once you are finally able to solve it, you’re going to be pretty proud of yourself and the people around you are going to be impressed because it really takes a lot to solve one of these cubes.
The quality of the individual parts are also inspected just after exiting the mold. Since thousands of parts are made daily, a complete inspection would be difficult. Consequently, line inspectors may randomly check the plastic parts at fixed time intervals and check to ensure they meet size, shape, and consistency specifications. This sampling method provides a good indication of the quality of the overall Rubik's cube production run. Things that are looked for include deformed parts, improperly fitted parts and inappropriate labeling. While visual inspection is the primary test method employed, more rigorous measurements may also be performed. Measuring equipment is used to check the length, width, and thickness of each part. Typically, devices such as a vernier caliper, a micrometer, or a microscope are used. Just prior to putting a cube in the packaging it may be twisted to ensure that it holds together and is in proper working order. This can be done by hand or by a turning machine. If a toy is found to be defective it is placed aside to be reworked later.
