The mechanism of a mirror cube works in exactly the same way as that of a standard 3×3 Rubik’s cube: the same axes, the same turning movements, the same internal structure. The difference lies not in the mechanism, but in the pieces themselves. Each piece has a unique dimension, causing the cube to change shape with every turn. The questions below explain step by step how this works, why solving it is so challenging, and which mechanism performs best.
Why does a mirror cube change shape while being solved?
A mirror cube changes shape because the individual pieces are not equal to one another. Each corner piece, edge piece, and center piece has a different height. When you turn a layer, pieces of different sizes end up in new positions, resulting in an irregular, asymmetrical exterior.
On a standard 3×3, all pieces are the same size, so the cube always maintains a perfect cubic shape. On a mirror cube, color is replaced by height as the identifying feature. All pieces are silver or gold in color, but each piece protrudes differently. Once the cube is scrambled, an irregular, sculptural shape emerges that looks different every time.
This makes the mirror cube visually fascinating, but also more cognitively demanding. You can no longer rely on color patterns. Instead, you must recognize the geometry of each piece and reason about where it belongs based on its dimensions and position.
How does the internal mechanism of a mirror cube differ from a standard 3×3?
The internal mechanism of a mirror cube is identical to that of a standard 3×3. Both puzzles use a central axis system with six fixed center pieces, around which eight corner pieces and twelve edge pieces can rotate freely. The difference lies exclusively in the external stickers or molded pieces, not in the internal workings.
A mirror cube is essentially a 3×3 mechanism with modified plastic pieces. The pieces are cut to have different thicknesses, but they click into the mechanism in exactly the same way as on a regular cube. The same algorithms you use for a standard 3×3 therefore work on a mirror cube as well, because the underlying structure is identical.
This is also why speedcubers who are already familiar with the 3×3 can solve the mirror cube relatively quickly. The motor skills and algorithmic knowledge are transferable. The challenge shifts from algorithmic to spatial-visual reasoning.
What are the different pieces of a mirror cube and how do they move?
A mirror cube consists of the same three types of pieces as a 3×3: eight corner pieces with three faces, twelve edge pieces with two faces, and six center pieces. Each type of piece has a fixed, unique dimension. The corner pieces each have a different combination of thicknesses, the edge pieces vary in width, and the center pieces differ in height.
The center pieces are fixed to the central axis system and never change position relative to one another. They determine the orientation of each side. The corner and edge pieces move freely along the axes and can be swapped by turning layers.
What makes movement on a mirror cube unique is the consequence of that movement. Because the pieces have different thicknesses, the outer contour of the cube changes with every turn. Some pieces protrude significantly, while others sit nearly flush. This constantly changing geometry is precisely what gives the mirror cube its distinctive, sculptural appearance during solving.
Why is a mirror cube harder to solve than a standard Rubik’s cube?
A mirror cube is harder to solve than a standard Rubik’s cube because you cannot use color as a guide. Instead of colors, you must recognize the dimensions of each piece and determine whether it is in the correct position. This requires stronger spatial intelligence and greater attention to detail.
On a standard Rubik’s cube, you can immediately tell when a piece is in the wrong place: the color is off. On a mirror cube, all pieces are the same color, and the only clue is shape. An edge piece that is slightly too thick or too thin for its position only becomes apparent when you look carefully at the overall contours of the cube.
In addition, the orientation of pieces on a mirror cube can also be wrong without it being immediately obvious. A corner piece may be in the correct position but rotated incorrectly, which only becomes visible when you examine the cube up close and compare the thicknesses. This makes debugging errors more time-consuming than with a color-based puzzle.
What type of mechanism does the best mirror cube have?
The best mirror cubes use a modern magnetic 3×3 mechanism with adjustable tension and magnets in the corner and edge pieces. This ensures stable, precise turning movements, which is especially important for a mirror cube because the uneven pieces can create more resistance in cheaper mechanisms.
In cheaper mirror cubes, you often find a basic plastic mechanism without magnets. This works functionally, but the turning movements feel less smooth and the cube can lock up more easily, especially when the uneven weight distribution puts more pressure on the internal system.
Magnetic versus non-magnetic
A magnetic mechanism offers greater control with every turn. The magnets ensure that layers click precisely into position, reducing the risk of overshooting. For a mirror cube, where you already need more cognitive attention for the geometry, that added stability is a clear advantage.
Adjustable tension
The best mechanisms allow you to adjust the tension of the layers. A slightly tighter mirror cube behaves more predictably, which helps with placing pieces accurately. Loose tension on a mirror cube can lead to unintended turns caused by the excess weight of protruding pieces.

Veelgestelde vragen
Can I solve a mirror cube using the same algorithms as a standard 3×3?
Yes, the algorithms for a standard 3×3 work fully on a mirror cube, because the internal mechanism is identical. The difference is that when executing algorithms, you pay attention to the dimensions of the pieces rather than their color. If you know the standard beginner method or CFOP, you can apply it directly, as long as you learn to identify the correct pieces based on their shape and thickness.
How do I recognize which piece goes where when all pieces are the same color?
Each piece has a unique combination of thicknesses and dimensions that you can compare to the center pieces of each side. The center pieces are your reference point: an edge piece or corner piece belongs in a position where its thickness matches the surrounding center pieces. A useful tip is to keep the cube next to a solved reference while you are learning, until you know the dimensions by heart.
What is the best way to start solving a mirror cube as a beginner?
Start by learning to solve a standard 3×3 if you cannot already, because the methods transfer directly. Once you have mastered the layer-by-layer method, begin by learning to identify the center pieces of the mirror cube and build up layer by layer from there. In the beginning, take your time comparing the thicknesses of pieces rather than turning quickly.
Can a mirror cube lock up or get damaged because of the uneven pieces?
With cheaper mirror cubes that have no magnets and little adjustable tension, the cube can indeed lock up more often, because protruding pieces put more pressure on the mechanism. You can fix this by tightening the tension slightly or by choosing a model with a magnetic mechanism. Regularly lubricating the mechanism with cubing lube also significantly extends its lifespan and improves turning feel.
Is a mirror cube suitable for children, or is it too difficult for beginners?
A mirror cube is generally suitable for anyone who can already solve a standard 3×3, but it is less ideal as a first puzzle for young children. The absence of color makes the puzzle more cognitively demanding and can be frustrating without prior knowledge. For children who already have experience with the Rubik's cube and are ready for a new challenge, the mirror cube is an excellent next step.
What is the difference between a gold and silver mirror cube, and does it matter for solving?
The difference between a gold and silver mirror cube is purely aesthetic: the color of the stickers or plastic differs, but the puzzle structure and mechanism are identical. It makes no difference whatsoever for solving, since with both versions you rely entirely on the geometry and dimensions of the pieces. The choice is therefore entirely a matter of personal preference.
How do I know when my mirror cube is fully solved?
A solved mirror cube has a perfect, symmetrical cubic shape in which all sides are flat and even. If any pieces are still protruding or the contours are irregular, at least one piece is still in the wrong position or the wrong orientation. Check this by looking at the cube from all sides and verifying that the edges of each layer line up neatly.
