Solution 4, Final Layer Position then Orient
REMEMBER: Before starting any algorithm, make sure that the front (dark grey) face is facing you and the top layer is on the top.
The aim of this section is to take you from this

|
to this
|
|
solving Rubik's Cube.
|
This solution assumes that you can solve the first two layers.
Important: To successfully solve the top layer each step must be completed in the order it appears on this page.
Step 1. Positioning The Edges
If all four edges are are in the right position then go to, "Step 1: Positioning The
Corners". Determining whether or not an edge is in the correct
position may be difficult because they are disoriented, the best thing to do is
ignore the top face colour and concentrate on the other colour. You can learn
just one algorithm and use it to solve the positioning of the edges, however,
you will need to use it twice if the rotation of the edges is the opposite clock
to the algorithm you learn. Rotating the Middle on its own reduces the size of the algorithms,
making them easier to remember.

Step 2. Positioning The Corners
|
If the corners are in the correct position then go to, "Step 3: Orienting The
Corners". If not then the front face has the correctly positioned corner on the right as represented
yellow in the diagram on the left. This may be difficult to detect because the corners
are disoriented. Check that the colours match the three adjacent centres. You can make it easier by ignoring the up face colour and concentrating on the other two.
You can use just one algorithm, which may have to be performed twice to correctly position all four corners. The
algorithm below moves the gold corners in an anti-clockwise direction.

You can use this algorithm to rotate the gold corners in a clockwise
direction. Note the front face has changed.
Step 3. Orienting The Corners
|
If all four corners are correctly oriented then go to, "Step 4: Orienting The
Edges".
If none are correctly oriented then it doesn't matter which face you use as the front face for the algorithm, however, once you have chosen one you must keep it until all the corners are correctly oriented. If there are two or three incorrectly oriented corners then the first incorrect corner
gold in an anti-clockwise direction from a correct corner yellow as in the image to the left determines the front face.
You will mess up the bottom two layers when orienting the top layer corners, however, when the final corner is correctly oriented the bottom two layers reset. The most common mistake with this algorithm, causing the top two layers to be messed up once the corners are oriented correctly, is not making the last move of the algorithm because you can see the corner is correctly oriented on the second last rotation. So it doesn't hurt to count them off 1 t0 8 before checking.
Complete the sequence then check to see if the corner is correctly oriented (hint concentrate on the top row only) if not repeat the complete sequence, when a corner is correct keeping the original front face rotate the up face clockwise so that the next disoriented corner has taken the place of the one you have just corrected. Continue this process until all of the bottom corners are correctly oriented then rotate the up face to complete the solution.

This algorithm rotates each corner in a clockwise direction. You need
perform the algorithm three times for the first two layers to reset.
Consequently, if you have two disoriented corners one will need the algorithm to
be performed twice. Generally when there are four corners to be oriented
two of them will require the algorithm to be performed twice.
When there are three corners to be oriented you will either perform
the algorithm once for each corner or twice for each corner. To
overcome the need to perform the algorithm twice for each
corner if
the corners need to be rotated anti-clockwise to be oriented correctly
you can use the following algorithm. Note the front face has
changed and you now rotate the top face anti-clockwise to the next
disoriented corner.
Step 4. Orienting The Edges
If all four edges are correctly oriented you are done. Otherwise you
are nearly there, but these are two whopper algorithms. However, rotating
the equator/middle layer on its own shortens them quite a bit.

NOTE: If you are solving a
cube with pictures, letters or numbers on the faces, such as a Sudoku
cube, this solution will more often than not leave you with centres that
are not correctly oriented so the following statement is not strictly
correct. For a solution for picture cubes and algorithms for
rotating centres see 3x3x3 Extras.
That's it, you have solved Rubik's Cube, happy cubing.
