# Solving a Rubik's Cube

This is a collection of the routines that I use to solve a Rubik's cube. It is based on a 7 step method where you solve one layer at a time. You can start from any color, but convention is to start from the White face.

## Orientation / Terminology

 F - Front B - Back R - Right L - Left U - Up D - Down

Front is the side facing you, without regard to color. An appostrophe (') is added to denote a counter-clockwise step.

For example:

• R' - Turn right side counter-clockwise
• D - Turn D Side (Bottom) clockwise
• F2 - Turn Front side twice

Two other reference terms:

• Corner - Fairly obviously any of the 8 corner pieces
• Edge - The piece between two corners

## 1 - White Cross

Move a white edge piece to the bottom, facing down. Rotate the piece to line up with correct center color. Rotate to Top.

## 2 - Solve White corners

Move white corner piece under its correct position. It can be in one of three positions as shown.

 A: R'  D'  R B: F  D  F' C: R'  D2  R  D  R'  D'  R

## 3 - Solve Middle Layer

Turn over so that yellow is on top. Move an edge piece into position shown and then move it Left or Right to put in in position.

 R: U R U' R' U' F' U F L: U' R' U R U F U' F'

## 4 - Make a Yellow Cross

All yellows will be in the top layer, but many will not be facing up. The first step is to make a yellow cross. The example is a simplification of what you might see. There might be other yellows facing up, but look for the closest pattern to one on the example below.

 A: F R U R' U' F' B: F U R U' R' F'

## 5 - Bring all Yellow to Top

Step 4 will leave a yellow cross in one of 7 possible configurations. The arrow points to the working face.

 Fish Right: R U R' U R U2 R' Fish Left: R' U' R U' R' U2 R

The other configurations will take two or more passes to get all yellows facing up.

## 6 - Find Headlights / Solve corners

Once all the yellows are facing up, you need to arrange the side colors. I start with the corners. Find a side with "headlights" (two solved corners), work with headlights on back, and run the routine. If there isn't a side with headlights, do the routine to create them, then run again.

 L' U R' D2 R U' R' D2 L R

## 7 - Solve Edges

Once the corners are solved there are several forms the edge pieces can take. If there is a solved side, put it on the back and run routine. If there isn't a solved side, use the routine once to create one, then run again.

 F2 U R' L F2 R L' U' F2 U' U

To move the centers Counter-clockwise, just switch the two steps shown above.
