![]() (Ri, L) (Bi, F) (Ui, D) (Ri, L) The first and last algorithms are the same, and you must repeat them as shown. For example, in the first algorithm, (Ri, L), You turn the right side counter-clockwise, and you turn the opposing side clockwise. 4) Rotate the entire cube so the orange face is front. 2) Rotate the upper face 90 degrees U 3) Rotate the bottom face 90 degrees B. 1) Hold the cube with the blue face front. Algorithms in this project are grouped together using parenthesis (), much like coordinates on a graph. Time to do some tricks It is important to start every trick with a solved cube. lets get solving solve layer ONE solve the middle layer solve THE. As you will see, the algorithms use one inverted movement, and one standard movement of the opposing side. an inverse or counterclockwise turn of the face. Note that we match the red side with the red center. If your cube has logos on four faces and solid colors on two of the faces, orient the cube so the solid color is on top and the logo to be rotated is on the left. Shown here are your two starting positions: Moving the Red/Green piece into the middle section. Since it is impossible to rotate just one piece 90 degrees on a cube, this move has the side effect of rotating the top middle-center piece 90 degrees counterclockwise. Each move depends on the orientation of the middle piece. To solve this, you will use four algorithms, each made up of two corresponding movements. Now, to solve the middle layer, we usually need to move a piece from the Top into the middle layer. (You can impress your friends by saying that you used and algorithm to solve this.) An Algorithm is just a set of rules used in problem solving. Example: Ri = Right side, inverted (counter-clockwise) D = Down (clockwise) These notations make up Algorithms which sounds fancy and smart, but is actually quite simple. Moving the Blue/Orange piece into the middle section. F Front (the side that faces you) B Back (the side that faces away from you) BT Bottom (The side that faces down) R The right side. Note that we match the red side with the red center to start this move. Before you start, you will have understand some basic notation, or these steps will confuse you. Shown here are your two starting positions: Moving the Red/Green piece into the middle section. This is very important, because if you reverse the direction for which you turn the side, it can mess you up. Each move depends on the orientation of the middle piece. This goes after a side abbreviation, and it means that you turn the specified side counter-clockwise, as if it were facing you. F = Front (the side that faces you) B = Back(the side that faces away from you) BT = Bottom(The side that faces down) R = The right side L = the left side * = Inverted. Before you start, you will have understand some basic notation, or these steps will confuse you.
