Step 1

The 1st Layer When the layer is fully solved, your puzzle will look like this:
No specific algorithm.
The placement of the pieces should remain intuitive.
Here are the main steps:
|
The Centers
|
The Edges
|
The Corners
|
|
Step 1 bis
|
The Centers of the 2nd Layer
You must ensure that all centers are correctly oriented; if so, everything is fine.
Otherwise, you have one case for each incorrectly oriented center.
Place the centers to be oriented as shown opposite.
When all centers are correctly oriented, your puzzle will look like this:
|
|
Step 2
|
Edges of the 2nd layer When all edges have been processed, your puzzle will look like this:
Note: we don't know if the edges are correctly oriented, which is why there is no case c and step 2 bis may be necessary.
|
Case a The edge is on the 3rd layer to the right
The algorithm allows it to be placed on the 2nd layer.
|
Case b The edge is on the 3rd layer opposite
The algorithm allows it to be placed on the 2nd layer.
|
|
Step 2 bis
|
Parity of an edge of the 2nd layer The number of misoriented edges of the 3rd layer must be even (0, 2, or 4). If so, everything is fine.
Otherwise, if it is odd, an edge of the 2nd layer is misoriented; you have two scenarios (for 1 or for 3).
Position the misoriented edges as shown opposite.
When the number of edges in the third layer is even, you will have one of the following four scenarios:
|
|
|
|
|
|
|
|
|
|
1 misoriented edge
|
3 misoriented edge
|
|
Step 3
|
Edges of the third layer When all the edges have been processed, your puzzle will look like this:
Note: there is no edge placement.
|
Orienting the edges - Case a
|
Orienting the edges - Case b
|
|
Step 4
|
Corners of the third layer When all the corners have been processed, your puzzle will look like this:
Note: there is no corner placement.
|
Orienting the corners
Depending on your configuration, you should apply the algorithm a maximum of 2 times!
Remember to orient your cube correctly to avoid running the algorithm more than necessary, i.e., not necessarily with the 3rd layer at the top.
