Look in the 2nd color of the border piece. Locate a border piece situated on the upper face that doesn’t have any Yellow inside. Most of the recent approaches have their origins in these alternatives. Here we’ve got a Cube that is disassembled 2, here is 8 Corner bits and the Core. You need to find which color goes by assessing the corner bits. When yellow and white centers are done, assess the corner bits to determine the locations of the other four centers. Start with the 2×2 middle. By you need to make the 2×2 facilities and following that set the border bits. The difference is the 4×4 does not have a centerpiece that determines the color of an individual face.
