Xiaomiโs smart Rubikโs Cube is not just a puzzle, but a high-tech device with Bluetooth synchronization, light indicators and a mobile app. 3ร3, The Mi Smart Cube or Xiaomi Mijia Rubik's Cube are equipped with spin sensors, backlights and the ability to track assemblies through a smartphone, but even with these "chips" the main task remains the same - to return all colors to their places.
If youโre picking up a Xiaomi cube for the first time, donโt rush to throw it in the box after the first failed attempt. In this article, weโll break down the step-by-step build algorithm, talk about the hidden features of the smart cube, and show you how to use the Mi Home or Xiaomi Wear app for training. And youโll also learn why the cube from Xiaomi is going faster than the classic one, it uses a magnetic mechanism that fixes the edges and prevents accidental scrolling.
How is Xiaomi smart cube different from the usual?
At first glance, the Xiaomi Mi Smart Cube looks like a standard Rubikโs Cube. 3ร3, But inside, there are technologies that make the assembly process easier:
- ๐น Magnetic mechanism: The edges are fixed when you turn, which reduces the number of random shifts, which is especially useful for beginners who are not yet accustomed to precise movements.
- ๐ฑ Bluetooth synchronization โ the cube is connected to the smartphone via the Mi Home or Xiaomi Wear app, where you can track build time, number of moves and progress.
- ๐ก Illumination of faces โ in some models (for example, Xiaomi Mijia Rubikโs Cube Pro) there are LED-Indicators that suggest the right moves.
- ๐ Built-in battery โ enough charge for several months of active use (charged via USB-Type-C).
But the basic principle of the build is the same: you have to build all the faces of the same color, and the only difference is that Xiaomi's smart cube forgives some errors by magnetically fixing it, for example, if you accidentally scroll the edge too hard in a classic cube, you have to start over, and here the mechanism pulls the parts to the right position.
Preparation for assembly: what you need to know before starting
Before you start building, check out a few key points:
- Charge the cube - if the indicator flashes red, connect it to charge for 10-15 minutes. The discharged cube can turn off during assembly.
- Sync with your smartphone โ install the Mi Home app (for the first time) Android/iOS) And you can plug the cube in via Bluetooth, and that'll help you track progress.
- Lighting โ collect the cube in good light to avoid confusing colors (especially blue and purple in some models).
Also note the starting position. Xiaomi's smart cube has an automatic stirring feature -- just press a button on the case or select an option in the app. If you're a beginner, start with a simple combination where one facet (usually white) is already assembled.

In the Mi Home app, you can turn on the Learning mode, where the cube tells you the first moves with light signals, which will help you understand the logic of the build.
Step-by-step: how to build a Xiaomi cube in 5 stages
We're going to break down a newcomer method that's guaranteed to work even if you've never held a Rubik's Cube in your hand before, and it's divided into 5 steps:
- Assembly of the first layer (cross) + corners).
- Second layer assembly.
- Cross assembly on the third layer.
- Arrangement of the corners of the third layer.
- The final finish (turning corners).
At each stage, we're going to use algorithms, sequences of turns that lead to the desired result. Don't be intimidated by terms like "right slice" or "left corner" -- there's a table below that explains the notations.
โ๏ธ Preparation for assembly
Stage 1: Assembly of the first layer (white cross) + corners)
Let's start with the white face (in a classic cube it is usually the opposite of yellow, but in the Xiaomi Mi Smart Cube the color scheme may differ - check by the instructions) The goal is to collect a cross of white edges and correctly place the white corners.
Algorithm for the cross:
- Find the white center, it will be your top edge.
- Pick up 4 white edges (details with two colors: white) + others) and place them around the white center so that the second color coincides with the center of the side face.
- If the edge is incorrect (for example, white on the side), use the formula: F' U' L' U (where F is the front face, U is the top, L is the left).
After you've assembled the cross, move to the corners, the white corner should be below, below its place.
R U R' U'(Repeat for all four corners).
What if the corner is not in its place?
Step 2: Assembly of the second layer
Now, flip the cube so that the white face is on the bottom, and your job is to put the middle layer together by aligning the edges with the centers.
The algorithm for the middle layer:
- Find an edge on the top layer without a yellow color (for example, red-blue).
- Turn the top face (U) so that the color of the edge coincides with the center on the right or left.
- Use the formula: U R U' R' U' F' U F' U F (if the edge needs to be inserted on the right) or U' L U F U' F' if the edge needs to be inserted on the left.
Repeat for all four edges. If the edge is already in place but inverted, use any of the formulas to take it out, and then insert it again.
Stage 3: Cross on the third layer (yellow)
Turn the cube up with a yellow face. Your goal is to assemble a yellow cross. There are 4 options for the yellow edges.
| Option | View from above | Formula |
|---|---|---|
| Line | โ | F R U R' U' F' |
| Corner | โ | R U R' U R U2 R' |
| Two parallel lines | โฌ | R U R' U R U' R' U R U2 R' |
| Ready cross | โฌ | Move on to the next stage |
Once you've applied the formula, the cross will be assembled, but the colors of the side faces may not match. It's OK to fix it in the next step.
Step 4: Arrangement of the corners of the third layer
Now you need to place the angles of the yellow face correctly, turn the cube so that at least one corner stands in its place (the colors of the side stickers coincide with the centers).
Algorithm (if no corner is in place):
U R U' L' U R' U' LRepeat until the corners are right. In the Xiaomi smart cube, you can turn on the hint app, it will flash with the LED when the angle is in place.
Stage 5: Final corner turn
The last step is to turn the corners so that the yellow face becomes uniform.
R' D' R DRepeat it until the yellow color is on top at all corners. If one corner is already yellow, hold it front-left and apply the formula.

In the Xiaomi cube, the magnetic mechanism holds the edges when you turn, so the formulas work more accurately than in the classic cube.
Common Mistakes and How to Avoid Them
Even with a smart cube from Xiaomi, beginners are waiting for typical mistakes.
- ๐ Flower confusion โ some Xiaomi models use pink instead of orange and turquoise instead of green. Always check the edge centers.
- ๐ Discharged cube - if the cube is disconnected during assembly, it can reset the progress in the application. Charge it to 100% before starting.
- ๐คฏ Forgotten algorithms โ donโt try to memorize all formulas at once. use a cheat sheet in the Mi Home app or print out a table.
- ๐งฒ Too strong turns โ the magnetic mechanism fixes the edges, but if you twist too sharply, you can knock down the already collected layers.
Another mistake is ignoring cube cues. LED-With indicators (e.g. Xiaomi Mijia Rubik's Cube Pro), LEDs flash if you make an algorithm error!
๐ก
If the cube is no longer responsive to turns, reset it to the factory settings: press the button on the case for 10 seconds. After reset, it will automatically mix.
How to Use the Mi Home App for Exercise
The Mi Home or Xiaomi Wear app makes assembling a cube a fun exercise. Here's what you can do with your smartphone:
- ๐ Statistics -- the app records build times, moves, errors, and you can compare your results with your friends.
- ๐ฏ Difficulty modes โ from โFor beginnersโ (with hints) to โExpertโ (without help).
- ๐ Automatic stirring โ the cube itself is stirred after each assembly so you learn to assemble different combinations.
- ๐ Achievements โ Virtual rewards can be received for quick assembly or small number of moves.
To connect the cube:
- Open Mi Home and click Add Device.
- Select the category โToysโ or โSmart devicesโ.
- Turn on the cube (press the button for 3 seconds) and wait for the appearance in the list.
- Confirm the connection, the cube will flash green.
In the application settings, you can include:
- Sound prompts (voice assistant will tell you the next move).
- Vibration on error.
- A dark theme for a comfortable assembly in the evening.

Secrets and life hacks for quick assembly
Once you have mastered the basic method, you can move to speed cubing. Here are some life hacks for the Xiaomi Cube:
- โก Use magnetic fixation - in a smart cube, the edges are "attracted" to the correct position, so you can make turns a little less carefully than in a classic cube.
- ๐ฎ Practice with a timer โ there's a built-in stopwatch in the Mi Home app. Set goals: for example, to assemble a cube in 2 minutes, then in 1.5, and so on.
- ๐ Learn the algorithms in practice โ instead of cramming formulas, just repeat them on a cube until your hands remember the movements.
- ๐๏ธ Watch out for centers โ in the Xiaomi Cube, the edge centers are sometimes highlighted, which helps you navigate faster.
Another secret: some Xiaomi models have a Backup mode, you assemble the cube as usual, and then the app shows you how to disassemble it in as few moves as possible, which is a great workout for memory and understanding mechanics.
There are algorithms for advanced users OLL and PLL (The last layer in 1-2 moves, but it is better to master them after you learn how to collect the cube in 1-1.5 minutes.
๐ก
In the Xiaomi cube, the magnets are arranged so that they reduce friction between the faces, which allows you to turn faster, but it takes getting used to it, because at first it may seem like the cube is "too light."
What to do if the cube breaks or does not turn on
Despite the robust body, Xiaomiโs smart cube can fail. Here are the typical problems and solutions:
| Problem. | Possible cause | Decision |
|---|---|---|
| Not included. | Battery discharged | Connect to charging for 30 minutes (use the original USB-Type-C cable) |
| Not connecting to the phone. | Bluetooth failure | Reboot the cube (press the button for 10 seconds) and the phone, then repeat the sync. |
| The edges are scrolling tightly. | Dust or dirt. | Gently blow the cracks with compressed air or wipe with a soft brush |
| LEDs are not working. | Software failure | Reset settings through the application (Settings) โ Reset) |
| The cube is scrolling itself. | Defect of the magnetic mechanism | Contact the Xiaomi Service Center (if warranty is required) |
If the cube has stopped responding to turns or makes creaks, do not try to disassemble it yourself - this can violate the tightness and magnetic fixation. In Xiaomi Mi Smart Cube models, the body is glued together, and if you open it neatly, you can damage the rotation sensors.
๐ก
Use a dry microfiber to clean the cube. Do not use liquids or alcohol, which can damage electronic components.
โ ๏ธ Warning: If the cube falls into water, immediately disconnect it and dry it in rice or silica gel for 24 hours.Do not turn it on until it is completely dry - this can cause a short circuit.
