How to Rebuild a Neocube: Step-by-Step Cube Guide
How do you rebuild a Neocube cube?
A classic Neocube set contains 216 magnetic balls, which can form a cube measuring 6 × 6 × 6 balls. The simplest method starts with a long chain, then a strip six balls wide, followed by stacking six layers.
- First, make one long chain.
- Fold the chain into a strip measuring 6 × 36 balls.
- Divide the strip into six 6 × 6 squares.
- Stack the individual squares on top of one another.
Magnetic balls offer many ways to build geometric shapes, patterns and models. However, after taking a more complex creation apart, it may not be immediately obvious how to return the whole set to its original cube.
Instructions for building a 6 × 6 × 6 cube
1. Join the balls into a long chain
Gradually separate the smaller shapes and add the balls one after another. You should end up with one continuous chain of all 216 balls.
2. Make a strip six balls wide
Count six balls from the beginning of the chain and place the next section directly beside them. Continue folding the chain back and forth in the same way.
The result will be a flat strip:
- 6 balls wide,
- 36 balls long.
If some sections repel each other, do not force the chain to bend. Change the direction in which you place it or rotate it slightly.
3. Form the first 6 × 6 square
Separate a section six balls long from one end of the strip. This creates the first square layer containing 36 balls.
4. Add the remaining layers
Gradually fold the remaining strip in 6 × 6 sections, placing each square precisely on top of the previous one.
After six layers, you will have the finished cube:
6 × 6 × 6 = 216 balls.
If the cube becomes uneven
Remove the last layer again, align the lower squares and slowly place it back from one edge. Do not let the balls snap together suddenly.

Safety when assembling the cube
Small, strong magnets are not toys for children
- Keep them out of reach of children and pets.
- Do not use them as a bracelet, piercing or other jewellery.
- Do not put them in your mouth, nose or ears.
- After each session, check that no balls are missing.
- Stop using any balls that are cracked, chipped or corroded.
- Protect them from sudden impacts and high temperatures.
- If swallowing is suspected, seek medical help immediately.
Frequently asked questions
How many balls are in a classic cube?
A 6 × 6 × 6 cube contains a total of 216 magnetic balls.
Why do sections of the strip repel each other?
Like magnetic poles are facing each other. Rotate that section of the strip or place it from the opposite side.
What should you do if one ball is missing?
You cannot build a complete 6 × 6 × 6 cube without it. Search the work surface and surrounding area before continuing.
Can you build the cube without making a chain?
Yes, but starting with a chain and a 6 × 36 strip is usually the clearest method for a beginner.
Can the balls be damaged?
Yes. Neodymium magnets are brittle, and a sudden impact can crack them or damage their surfaces.
Summary
To assemble a classic cube, first make a chain of all 216 balls. Fold it into a 6 × 36 strip, then create six 6 × 6 layers.
Work slowly and do not let the balls collide sharply. Always check their number when finished and store the complete set safely out of reach of children.
Assemble magnets safely
Use neodymium balls only on a stable work surface and store them in a closed container when finished.
