Notation
Speed cube algorithms are represented by capital letters, numbers and [']. Each symbol represents specific rotation.
Rules are below:
Solving Steps
1.Solve white bottom - 2.Solve yellow top layer - 3.Solve the whole cube.
1.Solve white bottom
-
STEP 1:
Choose any face that contains white as bottom, find white corner at top layer;
-
STEP 2:
Turn corner pieces following formulas as below;
-
STEP 3:
Repeat these steps, until all bottom face are white.
If there's no white corners at top layer, perform R U' R' or RUR' once as shown, to put white corner at top layer.
2.Solve yellow top layer
-
1.
View from top, the yellow bars represent yellow pieces on the sides.
-
2.
Focus on top side, there are 7 cases in total. Perform the algorithm 4 or 5 once in cases which only one yellow corner is on the top.
-
3.
Make sure your cube is in the right position as the diagram view.
-
4.
The other 5 cases require two algorithms in a row (Alg = algorithm). Perform Alg 4 first.
-
5.
If you cannot find any of the above cases, it is because there is corner twist. Twist the corner piece in accordance to the cases.
3.Solve the whole cube
-
STEP 1:
Find corner pieces that have same colors, perform algorithm 6 once. If all the sides are the same color, skip step 2 to step 3.
-
STEP 2:
If the sides of the corner pieces are with different color. Perform algorithm 6 once. Then step 1.
-
STEP 3:
Up-side-down the cube, and performs step1. Till all of the cube is solved.
The principle of algorithm 6 is to replace left-back into right-back.
Mind the direction of L and L'
Solve 2 layers at the same time, perform if both layer sides are with different color.
The principle of this algorithm is to replace opposite angles of the whole cube.
