![]() ![]() One is for edge pieces which are to the right of the solving position and the second is for those on the left)Repeat that for the other three edge pieces.In a case that an edge piece is in its correct position but incorrectly oriented (see image), insert a wrong edge piece to this position, and as a result the wanted edge piece will go back into the top layer. (These are mirror algorithms which basically does the same. Choose an edge piece to begin with which is currently on the top layer, and locate it above the correct center piece to form an upside-down T shape (see image).In order to insert the edge piece into its position we'll use one of the following algs. ![]() Then solve it correctly.Step 3: Solving the edge pieces of the middle layerIn this step we'll solve the four edge pieces of the middle layer, and by that we'll actually complete the first two layers (a.k.a F2L).Flip the cube upside down so the solved layer will be on the bottom. ![]() The first is orienting the corner so the white sticker will show on one of the side faces (done by- R' D2 R D), then Solving using the second case solution (R' D' R).If a white corner piece is located on the top layer but in the wrong place (see wrong image above) or incorrectly oriented in its place, just insert a non-white corner there, and by that the white corner piece will go back to the bottom layer. Repeat that for the other three corners.Solving a corner that its white sticker is in opposite to the upper face (the third case above), is done in two steps. It doesn't matter how hard you will try scrambling the cube, it will just stay that way.Rubiks Cube Move notationsMove notations are made in order to convey a sequence of moves through writing. For example, the blue center piece will always be opposite to the green center piece (on a standard color-scheme cube). 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 that reason they are already 'solved'. There are three types of pieces: (see image)Corner piece: has three different color stickers on it (there are 8 corner pieces in the cube)Edge piece: has two different color stickers on it (there are 12 edge pieces in the cube)Center piece: has one color sticker on it (6 center pieces, all are attached to the core)The core is the inside of the Rubik's Cube, which holds all the pieces together and is attached to the center pieces with rotatable axes.Important! The center pieces are part of the core and subsequently cannot move relatively to each other. ![]()
