How to Solve QiYi Windmill Cube
Master the QiYi Windmill Cube with this definitive guide covering all sizes and solving techniques.
What Is a QiYi Windmill Cube?
The QiYi Windmill Cube is a 3x3 shape mod that morphs into a windmill shape when scrambled. It has “supercube” properties—center orientation matters—and comes in various sizes, from standard 3x3 up to 9x9. Understanding this foundation is key to mastering all windmill variations.

1. Understand Piece Nomenclature
The windmill cube’s unique shape requires recognizing edges, corners, and centers by shape as well as color.
2. Notation
- •Standard cubing notation applies: R, L, U, D, F, B (and primes for counterclockwise moves).
3. Solving Steps
Step 1: Make the White/Reference Cross
- •Align edge pieces with their centers.
- •Edges must match center piece orientation and shape.
- •Double-check orientation, as incorrect center orientation leads to parity issues later.
Step 2: Insert First Layer Corners
Position all corners with the correct orientation—use R’ D’ R D to insert corners.
Step 3: Solve the Second Layer
Use selection algorithms to place the second layer's edges. Algorithms are similar to classic 3x3 but extra attention is needed for piece orientation.
Step 4: Solve the Last Layer
- •Create the Yellow Cross: F R U R’ U’ F’ (repeat depending on pattern)
- •Permute Corners: Use standard PLL/OLL algorithms, but be aware of shape mods possibly hiding correct orientation.
- •Fix centers if necessary with dedicated center-rotation algorithms.
Detailed Numbered Instructions (3x3 Windmill Cube)
- 1.Create the Cross:
- 2.Find white edges.
- 3.Align with respective center shape/color.
- 4.Only move edges when orientation matches.
- 1.Complete the First Layer:
- 2.Insert corners using R’ D’ R D until solved.
- 1.Second Layer Edges:
- 2.Use U R U’ R’ U’ F’ U F or its mirror, as needed.
- 3.Edge shape can be misleading—focus on position, not just color.
- 1.OL/PLL (Last Layer):
- 2.F R U R’ U’ F’ to create the cross.
- 3.Sune Algorithm: R U R’ U R U2 R’ for corner orientation.
- 4.Use L’ U R U’ L U R’ U’ for permutation.
Unique Challenges: Parity and Supercube Features
- •Center Orientation Parity: If the cube appears almost solved but isn’t, check the orientation of the four colored centers. Dedicated algorithms are available to rotate centers without disturbing the rest of the cube: - Rotate center: [example algorithm needed for model, see advanced guides]
- •Piece Identification: Always analyze both shape and color, especially in higher-order windmill cubes.
Table: Common Algorithms Used (3x3 Windmill Cube)
| Step | Algorithm | Purpose |
|---|---|---|
| First Layer Corners | R’ D’ R D | Insert corners |
| Second Layer Edges (Up) | U R U’ R’ U’ F’ U F | Edges slanted upward |
| Second Layer Edges (Down) | U’ L’ U L U F U’ F’ | Edges slanted downward |
| Last Layer Cross | F R U R’ U’ F’ | Create last layer cross |
| Last Layer Corners | R U R’ U R U2 R’ | Orient corners (“Sune”) |
| Center Rotation | (Special) e.g., M’ U M U2 M’ U M | Fix rotated center (see supercube notes) |

2x2 Windmill Cube
- •Solving method: Nearly identical to a 2x2 Rubik’s Cube, but with shape-modded pieces.
- •Steps:
- 1.Complete the reference layer (often “white”).
- 2.Position last layer corners.
- 3.Orient corners using R’ D’ R D.

4x4 Windmill Cube
- •Reduction method: First, solve centers, then pair edges like a standard 4x4, then solve as a 3x3, accounting for parity.
- •Parity is common (e.g., two edges swapped or orientation issues). Use 4x4 parity algorithms.
- •Notable parity fix:

5x5 Windmill Cube
- •Solve centers → pair edges → reduce to 3x3 shape mod, using the same logic as above. Parity errors may appear and need correction.
6x6 to 9x9 Windmill Cubes
- •General Strategy: - Solve all centers. - Pair all edge groups. - Reduce to a 3x3 windmill shape mod, paying special attention to parity. - Higher likelihood of edge pairing parity (e.g., single edge flipped or 2-swapped).
