Have you mastered the normal Rubik’s Cube? Are you looking for some alternatives? Here’s the solution; a pyramid Rubik’s Cube. It is also known as the Pyraminx. This type of pyramid is actually a tetrahedron-shaped puzzle that you need to solve in a different way than an average cube. There are numerous positions.
Permute the corners. At this step, our goal is to place the corners of the last layer in their correct position, regardless of their orientation.- Locate two adjacent corners that share a color other than the color of the top layer (other than yellow in our case).
- Turn the top layer until these two corners are on the correct color side, facing you. For instance, if the two adjacent corners both contain red, turn the top layer until those two corners are on the red side of the cube. Note that on the other side, the two corners of the top layer will both contain the color of that side as well (orange in our example).
- Determine whether the two corners of the front side are in their correct position, and swap them if needed. In our example, the right side is green, and the left side is blue. Therefore the front corner on the right must contain green, and the front corner on the left must contain blue. If it is not the case, you will need to swap those two corners with the following algorithm:
Swap 1 and 2 : (2.a) - Do the same with the two corners at the back. Turn the cube around to place the other side (orange) in front of you. Swap the two front corners if needed.
- As an alternative, if you notice that both the front pair and the back pair of corners need to be swapped, you can do it with only one algorithm (note the huge similarity with the previous algorithm):
Swap 1 with 2 and 3 with 4 : (2.b)
