The Triangle Rubik’s Cube, also known as the Pyraminx, is a three-layered puzzle that can be solved using a variety of methods. The most common method is the beginner’s method, which involves solving the puzzle one layer at a time. However, there are also more advanced methods that can be used to solve the puzzle more quickly and efficiently. In this article, we will discuss the beginner’s method for solving the Triangle Rubik’s Cube.
The first step is to solve the bottom layer. To do this, hold the puzzle with the bottom layer facing you and turn the top layer until the desired piece is in the front-left corner. Then, turn the bottom layer until the piece is aligned with the front-left edge. Finally, turn the top layer again to insert the piece into the bottom layer. Repeat this process for the remaining three corners of the bottom layer.
Once the bottom layer is solved, you can move on to the middle layer. To solve the middle layer, hold the puzzle with the bottom layer facing you and the middle layer facing up. Turn the top layer until the desired piece is in the front-left corner. Then, turn the middle layer until the piece is aligned with the front-left edge. Finally, turn the top layer again to insert the piece into the middle layer. Repeat this process for the remaining four pieces of the middle layer.

Solving the Triangle Rubik’s Cube: A Masterpiece of Geometry
The Triangle Rubik’s Cube, with its unique three-dimensional shape and challenging rotations, offers a captivating puzzle experience. Embark on this mathematical adventure as we delve into the intricacies of solving this enigmatic geometric gem.
Understanding the Cube’s Structure
This triangular marvel comprises eight equilateral triangles organized into two rotating layers. Each layer features four edges and three vertices, creating a total of twelve edges and six vertices. The key to solving this cube lies in comprehending the different types of moves:
- Upper Layer Rotation: The top layer of the cube can be rotated clockwise or counterclockwise, rearranging the four triangles while keeping the edges and vertices intact.
- Lower Layer Rotation: Similar to the upper layer, the bottom layer can also be rotated independently, changing the positions of its four triangles.
- Horizontal Slice Rotation: A horizontal cut divides the cube into upper and lower halves. This move rotates the entire upper half clockwise or counterclockwise relative to the lower half, altering the positions of the edges and vertices.
- Vertical Slice Rotation: A vertical cut splits the cube into left and right halves. This move rotates the right half clockwise or counterclockwise relative to the left half, affecting the edges and vertices.
Understanding the Mechanism and Rotations
Mechanism Overview
The Triangle Rubik’s Cube, also known as the Pyraminx, consists of four corner pieces, six edge pieces, and a central axis. The corner pieces are connected by the edge pieces, which rotate freely around the central axis. The cube is solved by manipulating these rotations to align the colors correctly on each side.
Rotational Movements
| Rotation | Notation | Effect |
|---|---|---|
| Front Rotation | U | Rotates the front face clockwise |
| Front Inverse Rotation | U’ | Rotates the front face counterclockwise |
| Right Rotation | R | Rotates the right face clockwise |
| Right Inverse Rotation | R’ | Rotates the right face counterclockwise |
| Back Rotation | B | Rotates the back face clockwise |
| Back Inverse Rotation | B’ | Rotates the back face counterclockwise |
| Left Rotation | L | Rotates the left face clockwise |
| Left Inverse Rotation | L’ | Rotates the left face counterclockwise |
Objective
The ultimate goal of solving a Triangle Rubik’s Cube is to arrange the colors on each face so that each side is a single color. This requires understanding the rotational movements and applying them in a strategic order to manipulate the positions of the pieces.
Solving the First Layer
The first layer of a Triangle Rubik’s Cube consists of the three bottom rows. To solve it, follow these steps:
1. Orient the Corners
Rotate the cube so that one of the solved corners is facing upwards. Match a corner piece from the first layer to the correct color on the upward face. Rotate the face to insert the piece into the correct spot. Repeat for the other two corners.
2. Orient the Edges
Match an edge piece from the first layer to the correct color on the upward face. Insert the edge piece by rotating the corresponding side face. Repeat for the other two edges.
3. Permute the Edges
If the first layer edges are on the correct faces but not in the correct order, perform the following algorithm until they are in place:
| Algorithm | Description |
|---|---|
| U R U’ R’ | Clockwise quarter-turn of the top face, followed by a clockwise quarter-turn of the right face, then an anti-clockwise quarter-turn of the top face, and finally an anti-clockwise quarter-turn of the right face. |
| U R U’ L’ U R’ U’ L | Clockwise quarter-turn of the top face, followed by a clockwise quarter-turn of the right face, then an anti-clockwise quarter-turn of the top face, and finally an anti-clockwise quarter-turn of the left face, then a clockwise quarter-turn of the top face, a clockwise quarter-turn of the right face, an anti-clockwise quarter-turn of the top face, and an anti-clockwise quarter-turn of the left face. |
Navigating the Middle Layer
Once the bottom layer is complete, you can proceed to solve the middle layer. This involves matching the edge pieces on the middle layer with the corresponding faces on the top and bottom layers.
4. Matching the Edge Pieces
To match the edge pieces, look for an edge piece on the middle layer that is not in its correct position. Rotate the bottom layer until the piece is directly below its correct position on the middle layer.
Now, perform the following sequence of moves to insert the edge piece into the middle layer:
Table
| Algorithm | |||
|---|---|---|---|
| R U2 R’ U’ R U2 R’ |
| Algorithm | Notation |
|---|---|
| U R U’ R’ U’ F’ U F | (Up, Right, Up prime, Right prime, Up prime, Front prime, Up, Front) |
Repeat this algorithm until all corners are aligned correctly.
Orienting the Edge Pieces
To orient the edge pieces correctly, you must first identify the color of the center piece on the side of the cube where the edge piece belongs. Then, follow these steps:
- Hold the cube with the unsolved edge piece on the top layer.
- Rotate the top layer until the edge piece is directly above the center piece of the correct color.
- Perform the following sequence to insert the edge piece into the correct slot:
| If the center piece is on the front face: | If the center piece is on the right face: | If the center piece is on the back face: | If the center piece is on the left face: |
|---|---|---|---|
| R U R’ U’ | F R U R’ U’ F’ | L’ U L U’ L F L’ F’ | U L’ U’ L |
Repeat these steps for the remaining edge pieces.
Positioning the Corner Pieces
To proceed with positioning the corner pieces, it is necessary to turn the relevant faces on the bottom of the puzzle to bring the desired corner piece to the top of the puzzle.
Identifying the Correct Position
Inspect the top face of the puzzle and locate the corner piece you wish to position. Then, observe the order of the colors on that corner piece. For instance, if the corner piece has orange, green, and blue, then it should be placed in the corner where the orange face, green face, and blue face meet.
Orientating the Piece
Once you have identified the correct position, hold the corner piece between your thumb and forefinger. Orientate the piece so that the correct color is facing the corresponding face on the puzzle.
Inserting the Piece
Carefully insert the corner piece into the desired corner. Push the piece gently until it clicks into place. Ensure that it is securely attached and does not pop out when you release it.
Matching Colors
After inserting the corner piece, turn the relevant faces of the puzzle to align the colors of the corner piece with the colors of the adjacent faces. This step helps to ensure that the corner piece is correctly oriented.
Completing the Corner
Repeat steps 1 through 4 to position and orientate the remaining three corner pieces. Once all four corner pieces are in place, the first layer of the puzzle is complete.
Resolving Parity Issues
When you encounter a situation where the corners are oriented correctly but the edges are flipped, you have a parity issue. To resolve this, you need to perform a specific sequence of moves:
Step 1: Execute the “sune” algorithm
Do the following sequence: R U R’ U’ R’ F R2 U’ R’ U’ R U R’ F’
Step 2: Rotate the top layer 180 degrees
Turn the top layer of the cube 180 degrees clockwise.
Step 3: Repeat Step 1 and 2
Repeat steps 1 and 2 to bring the bottom edges back to their original positions.
Step 4: Perform the “anti-sune” algorithm
Do the following sequence: R U R’ U’ R’ F R2 U’ R’ U’ R U R’ F’
Step 5: Rotate the cube 180 degrees around the x-axis
Flip the cube upside down to bring the bottom edges to the top.
Step 6: Repeat Step 1 and 2
Repeat steps 1 and 2 to bring the top edges back to their original positions.
Step 7: Perform the “anti-sune” algorithm again
Do the following sequence: R U R’ U’ R’ F R2 U’ R’ U’ R U R’ F’
Step 8: Rotate the cube 180 degrees around the y-axis
Turn the cube clockwise around the y-axis (from the front).
Step 9: Repeat Step 1, 2, 5, 6, 7, and 8
Repeat steps 1, 2, 5, 6, 7, and 8 to resolve the final parity issue on the top layer.
Achieving a Perfect Solution
The ultimate goal of solving a Triangle Rubik’s Cube is to achieve a perfect solution, which means every face and layer of the cube is completely matched in color. The process of achieving this can be broken down into several steps:
1. Solve the Top Layer
Start by completing the top face by aligning the three edge pieces and the corner pieces matching them with the top centerpiece color.
2. Solve the Middle Layer
With the top layer solved, the next step is to solve the middle layer. This involves moving the edge pieces of this layer to their correct positions while maintaining the orientation of the pieces from the top layer.
3. Orient the Top Face
Once the middle layer is solved, the top face may not be oriented correctly. Use the PLL (permutation of last layer) algorithm to rotate the corners of the top face until they match the centers.
4. Permute the Top Face
After the top face is oriented, the next step is to permute the top face pieces to match the correct positions. Another PLL algorithm is used to achieve this.
5. Orient the Last Layer
With the top face and middle layer solved, the last step involves orienting the corners of the last layer. Another set of PLL algorithms can be used to correct any misorientations.
6. Permute the Last Layer
The final step is to permute the corners of the last layer. Similar to the top face, a PLL algorithm can be used to cycle the corners until they are in their correct positions.
7. Solve the Bottom Face
Although the cube is essentially solved at this point, the bottom face may still need to be rotated to match the other faces. Use a simple algorithm to rotate the bottom face until it aligns correctly.
8. Orient the Bottom Face
Similar to the top face, the bottom face may need to be oriented correctly. Use a simple algorithm to rotate the bottom face until the edges align with the corresponding edges on the side faces.
9. Permute the Bottom Face
The final step is to permute the edges of the bottom face to match the correct positions. Another simple algorithm can be used to cycle the edges until they are in their correct orientations.
10. Advanced Techniques
Once the basic steps are mastered, solvers can learn advanced techniques to optimize their solving times and improve their overall skills. These techniques include:
- Look-Ahead: Planning multiple moves in advance to minimize the number of unnecessary rotations.
- Finger Tricks: Developing efficient finger movements for faster execution of algorithms.
- Commutators: Using specific combinations of moves to cancel out unintended rotations.
