Use Formulas
Learn three basic formulas that give you specific directions on how to move your Rubik̵7;s cube. Each formula has you solve the corners, then each edge of your cube.
Move the corners of any face of your cube to their correct positions and orientations. Once you̵7;ve done this, you̵7;ll use each formula--A, B and C--to solve your cube. Formula A will help you move the remaining four corners to their correct spots. You don̵7;t need to worry about having the corners oriented correctly. Formula B will direct you to rotate the rest of the corner blocks to their correct orientations, meaning that all eight corners are now correctly placed and oriented. Formula C helps you move the edges into the correct positions.
Use Formula A to move the lower right corner of the top face of your cube within the first three moves. The next three moves will move the lower right corner back to its original spot. You can do the same six moves with the lower left corner of your cube on the bottom face of your cube.
The corner blocks are in the correct positions but their orientations may not be right. Formula B rotates the blocks in a counterclockwise direction. The first three moves take the lower right corner of the top face out of place and the last three moves move that corner back into place. If you do the same six moves in Formula B with the bottom face, then the top left, bottom left and bottom right blocks are rotated in a clockwise direction.
Using Formula C causes three edge block positions to be swapped going in a counterclockwise motion. As in Formulas A and B, the first three moves take out the lower middle block and the final three moves put it back. Again, you can use a variation of this particular formula to move the blocks clockwise by swapping out the right and left rotations.
Use Cube Notation
Learn not to think of your Rubik̵7;s cube as 27 different cubes, but as six fixed centers that you can rotate on their own axis. Your cube has eight corners and 12 edges you can rotate around the center of the cube. The color of the center cube is the color of that face--if the center cube is green, the face is green. You can̵7;t change this. With this method, you̵7;ll be memorizing some algorithms so that, when you get skilled at the moves, you can potentially solve your Rubik̵7;s cube in approximately 60 seconds.
Memorize some cube notations. These are: F is front face, B is back face, R is right face, L is left face, U is up face and D is down face. When you see a letter by itself (F) you turn that face 90 degrees clockwise. A letter with an apostrophe after it (B̵7;) tells you to turn that face counterclockwise. A letter followed by the number two (R2) is telling you to turn that face 180 degrees, but the direction to turn it isn̵7;t important. This instruction: ̶0;B D̵7; R2̶1; tells you to turn the back face 90 degrees clockwise, and then turn the down face 90 degrees counterclockwise and then turn the right face 180 degrees. To understand which direction--clockwise or counterclockwise--to turn the face you̵7;re working with, imagine you̵7;re looking straight at that face.
Remember, with each algorithm you̵7;re given to solve, you're working from the knowledge that the core of your cube is fixed the entire time you̵7;re working on that algorithm. You turn the faces around the core.
