When it comes to building the Rubik’s Cube, it’s not as hard as it looks. In all actuality, it will take about fifteen minutes and the instructions are easy to follow. When it comes to placing the colored tiles, make sure you pay attention to where you’re supposed to place them, because if you snap them in the wrong place, you won’t be able to remove them. Yes, you will still be able to use the Rubik’s Cube, but you won’t be able to follow along with the instruction guide on solving the puzzle.
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
