Understanding the Structure of a Rubik’s Pyramid
Layers
A Rubik’s Pyramid consists of four layers: the base, middle, top, and apex. Each layer has three triangular faces, forming a pyramid shape.
Triangles
Each face of the pyramid is made up of three equilateral triangles of different colors. The colors are arranged in such a way that each triangle has two adjacent sides of the same color and one side of a different color.
Cores
At the center of each layer is a triangular core piece that connects the faces. The core pieces are fixed in place and cannot be moved.
Axes
The Rubik’s Pyramid has three axes of rotation:
- Horizontal Axis: This axis runs through the center of the base and apex layers, allowing the pyramid to rotate left and right.
- Vertical Axis: This axis runs through the center of the left and right faces, allowing the pyramid to rotate up and down.
- Diagonal Axis: This axis runs through the center of the top face and one vertex of the base layer, allowing the pyramid to rotate diagonally.
Solving the Outer Two Layers
Once the bottom layer is solved, we can focus on completing the outer two layers. This process involves several steps:
Rotating the Corner Pieces
The first step is to rotate the corner pieces on the outer two layers so that they match the color of the center piece of the respective face. To do this, hold the pyramid such that the center piece you want to match is facing you and the corner piece you want to rotate is on the left. Then, perform the following sequence of moves:
1. Turn the pyramid clockwise or counterclockwise once.
2. Turn the pyramid Downward twice.
3. Repeat steps 1 and 2 until the corner piece is in the correct position.
After all the corner pieces on the outer two layers are in place, we can move on to the next step.
Swapping Edge Pieces
The next step is to swap the edge pieces on the outer two layers so that they match the color of the center pieces on the respective faces. To do this, hold the pyramid such that the center piece you want to match is facing you and the edge piece you want to swap is on the front edge. Then, perform the following sequence of moves:
1. Turn the pyramid clockwise or counterclockwise once.
2. Turn the pyramid Downward once.
3. Turn the pyramid clockwise or counterclockwise once again.
4. Repeat steps 1-3 until the edge piece is in the correct position.
Once all the edge pieces on the outer two layers are in place, the pyramid is almost solved.
Rotating the Top Layer
The final step is to rotate the top layer so that all the center pieces are aligned correctly. To do this, hold the pyramid such that the center piece you want to align is facing you. Then, perform the following sequence of moves:
Move | Description |
---|---|
Turn Clockwise | Turn the top layer of the pyramid clockwise once. |
Turn Counterclockwise | Turn the top layer of the pyramid counterclockwise once. |
Continue turning the top layer until all the center pieces are aligned correctly.
Orienting the Corners
Once you have reoriented the edge pieces and aligned the corners, you can proceed to orient the corners. This step involves rotating the corners until the color on the top face matches the color on the side face.
To orient a corner, hold the pyramid with the target corner facing you. Rotate the top face of the pyramid so that the target corner is in the front-left position. Then, perform the following algorithm:
**R U R’ U’ R’ F R2 U’ R’ U’ R U R’ F’**
**Detailed Explanation:**
- **R:** Rotate the right face clockwise.
- **U:** Rotate the top face clockwise.
- **R’:** Rotate the right face counterclockwise.
- **U’:** Rotate the top face counterclockwise.
- **R’:** Rotate the right face counterclockwise.
- **F:** Rotate the front face clockwise.
- **R2:** Rotate the right face twice clockwise.
- **U’:** Rotate the top face counterclockwise.
- **R’:** Rotate the right face counterclockwise.
- **U’:** Rotate the top face counterclockwise.
- **R:** Rotate the right face clockwise.
- **U:** Rotate the top face clockwise.
- **R’:** Rotate the right face counterclockwise.
- **F’:** Rotate the front face counterclockwise.
Repeat this algorithm for each corner that needs to be oriented.
Corner Position | Algorithm |
---|---|
Front-left | **R U R’ U’ R’ F R2 U’ R’ U’ R U R’ F’** |
Front-right | **R U2 R’ U’ R U R’ U’ R2 F R’ U’ R U R’ F’** |
Back-left | **L’ U2 L U’ L U L’ U’ L2 F L U’ L U L’ F’** |
Back-right | **R’ U R U’ R’ U R U’ R2 F R’ U’ R U R’ F’** |
Permuting the Corners
The next step is to permute the corners. This means moving them to their correct positions. To do this, hold the pyramid so that the corner you want to move is on top. If the corner is already in the correct position, skip this step. If the corner is in the wrong position, use the following algorithm:
- Hold the pyramid so that the corner you want to move is on top.
- Turn the top layer clockwise.
- Turn the middle layer counterclockwise.
-
Move Direction D Clockwise D’ Counterclockwise L Left L’ Right R Right R’ Left - Turn the middle layer clockwise.
- Turn the top layer counterclockwise.
This algorithm will move the corner to the correct position. Repeat this algorithm for each corner until all of the corners are in their correct positions.
Orienting and Permuting the Edges
Step 1: Identify the Corner Piece with Two Matching Colors
Locate a corner piece that has two colored sides that match.
Step 2: Match the Corner Piece to its Center
Rotate the pyramid so that the two matching colors on the corner piece align with the corresponding colors on the center piece.
Step 3: Insert the Corner Piece into the Side
Hold the corner piece against the side of the pyramid, aligning its matching colors with the matching colors on the center piece.
Step 4: Rotate the Pyramid
Rotate the pyramid clockwise or counterclockwise until the corner piece is inserted into the side correctly.
Step 5: Repeat for the Remaining Corner Pieces
Repeat steps 1-4 for the remaining three corner pieces, matching them to their corresponding colors on the center piece and inserting them into their correct sides. Once all four corner pieces are oriented and permuted, move on to the next step.
Corner Piece Colors | Center Piece Colors |
---|---|
Blue-Green | Blue-Green |
Red-Yellow | Red-Yellow |
White-Orange | White-Orange |
Black-Purple | Black-Purple |
Solving the Last Layer Corners
With the last layer edges in place, you’re now ready to tackle the final step: aligning the last layer corners. While the process may seem daunting, it’s actually quite straightforward. Here’s a step-by-step guide:
Step 1: Identify the Misplaced Corner
Inspect the last layer and locate the corner piece that is not facing the correct color. It may be rotated incorrectly or in the wrong corner.
Step 2: Position the Corner Above the Correct Space
Hold the pyramid so that the misplaced corner is directly above its correct location. If it’s not rotated correctly, rotate the pyramid until it is.
Step 3: Use the “X” or “Y” Move
To insert the corner, you’ll need to perform a series of moves known as the “X” or “Y” moves. The specific sequence you use will depend on the orientation of the corner. Refer to the table below for guidance:
Orientation | Move Sequence |
---|---|
Corner rotated 90° clockwise | X R U R’ U’ |
Corner rotated 90° counterclockwise | Y R U R’ U’ |
Corner rotated 180° | X R’ U R’ U’ R |
Step 4: Insert the Corner
Once you’ve performed the correct move sequence, the corner should now be facing the correct color. Push it down into place using your thumb.
Step 5: Repeat for Other Corners
Repeat steps 1-4 until all the last layer corners are aligned. Once all the corners are in place, the pyramid is solved!
Solving the Last Layer Edges
The next phase is aligning the edges of the last layer with their respective centers. Start by orienting the pyramid so that an unaligned edge piece is facing towards the front. This edge piece should have one side that matches the center square and one side that doesn’t.
Hold the pyramid with the unaligned edge piece at the bottom front corner. This is known as the “front-bottom” position.
Perform the following sequence:
- R (rotate the right face clockwise)
- D (rotate the bottom face clockwise)
- R’ (rotate the right face counterclockwise)
- D’ (rotate the bottom face counterclockwise)
- R (rotate the right face clockwise)
- D (rotate the bottom face clockwise)
- R’ (rotate the right face counterclockwise)
This will move the unaligned edge piece to the right-front position.
Repeat steps 3-6 for each of the three edges until all edges are aligned with their respective centers.
Note that if an edge piece is already in the correct position but needs to be flipped upside down, you can perform the following sequence:
- R (rotate the right face clockwise)
- D (rotate the bottom face clockwise)
- R’ (rotate the right face counterclockwise)
Positioning the Last Layer Edge Pieces
Step 8: Completing the Last Layer
Once the first two layers are complete, the last step is to position the remaining edge pieces on the top layer. Here’s a detailed breakdown of the process:
- Identify the edge pieces on the top layer that need to be positioned.
- Hold the Pyramid in one hand and the edge piece in the other.
- Align the edge piece with the corresponding slot on the top layer, ensuring that the colors match.
- Slide the edge piece into place while rotating the Pyramid simultaneously to prevent rotations on the other solved layers.
- Repeat steps 3-4 for all the remaining edge pieces.
Table: Edge Piece Positioning Scenarios
Scenario | Rotation Sequence |
---|---|
Edge piece is already in the correct position | No rotation necessary |
Edge piece is on the opposite side of the Pyramid | D L’ D’ |
Edge piece is on an adjacent side | D’ R D |
Note: The rotation sequence assumes that the edge piece is facing you on the top layer. If it’s facing away from you, perform the reverse rotation sequence (e.g., D L D L’).
Fine-Tuning and Solving
9. Solving the Remaining Side
After the previous steps, you’ll have one unsolved side. Focus on positioning the corner pieces on that side correctly.
Hold the pyramid so that the unsolved side is facing you. Rotate the bottom layer until a corner piece that matches the unsolved side is in the bottom right or left corner.
Perform the following sequence to move the corner piece to its correct position:
D’ U D (L’ U’ L) D’ U’ D F D’ F’
Repeat this sequence if necessary to move the remaining corner pieces to their correct positions. Once all corner pieces are solved, the pyramid is solved.
