This means the block is not in its correct place, and its color on the cube does not matter. With all the corner pieces in their correct positions, the final and the most fun stage is to orient them correctly, aka get those yellow sides facing upwards. Rotate the upper row to get the edge pieces you need to be aligned with the sides they need to move to. This is the very reason that algorithms exist in the first place. In essence, the first step is to observe all of the colors of the cube, and the patterns that appear as you twist the puzzle. In order to write down sequences of movements on the cube, we use a notation of six main letters: U for Up D for Down L for Left R for Right F for Front B for Back These letters are used in sequences known as algorithms, and you just perform each letter in the algorithm from left to right. Some cubers may use the notation 2F (not to be confused with F2 which would mean a 180-degree turn of F). These are standard terminology, and they are as follows (courtesy of The OfficialRubik's Cube Site): Note the use of the letter "i" on some moves. This should be relatively straightforward for most edges except the last two. Like all Rubik's cubes, make sure you intimately understand the mechanics of the puzzle, such as what the edge, corner, and centerpieces are, as well as move notations and other terminology. Then, we temporarily break up our solved centers to match these edge pieces and move the now-solved edge pair into the top layer. You will also see greyed-out squares on most images. We aim to get the yellow side of each edge piece facing upwards. You will usually need to do this two or four times. If there are only the letters turn it clockwise, if there is the letter and ' turn counterclockwise. Well done, you are 66% of the way there.
