Product Description
YuXin HuangLong Teraminx – Refined 7-Layer Megaminx Performance
The YuXin HuangLong Teraminx is a high-quality 7-layer megaminx puzzle designed for cubers who want smoother performance than entry-level teraminxes. Sitting between the budget ShengShou Teraminx and the premium magnetic DianSheng model, it offers a more refined turning feel while remaining non-magnetic.
A teraminx is the 7-layer version of the megaminx, making it the dodecahedral equivalent of a 7x7 cube. With hundreds of pieces and extremely long solves, it is one of the most impressive mass-produced twisty puzzles available.
🔍 What Is a Teraminx?
The teraminx belongs to the megaminx puzzle family and increases the complexity dramatically compared to smaller variants.
- 7 layers per face
- 12 faces (dodecahedron shape)
- Hundreds of moving pieces
- Extremely long solving times
Most solving methods involve reduction techniques similar to solving a 7x7 cube: centres are solved first, edges are paired, and the puzzle is then completed like a standard megaminx.
⚙️ Performance & Turning
The YuXin HuangLong Teraminx improves on older large minx designs with smoother turning and a more refined internal mechanism. While still a very large puzzle, the turning feel is noticeably cleaner than basic teraminxes.
- Smoother turning than entry-level teraminxes
- More refined internal mechanism
- Stickerless bright plastic
- Stable piece design
This makes it a great option for cubers who want better performance than the ShengShou Teraminx but do not need the premium magnetic design of the DianSheng version.

Returns Policy
Returns
If the item is faulty:
If you find a fault with the product within 30 days that significantly restricts your ability to use it you may request to return it for fixing or a replacement if fixing is not possible. Once you have provided reasonable evidence that the product is faulty and cannot easily be fixed then you can return it to 90 Culley Court, Peterborough, PE2 6WA
I will then attempt to fix it myself, usually I will be able to easily fix it and can then send it back to you quickly, if I am unable to fix it then I can offer a replacement of the product or a refund or similar product if the item is no longer in stock.
Please note that if a cube pops, this is not a reasonable justification for a return, all good cubes have the potential to pop occasionally, if it happens frequently you should consider tightening the tensions or turning more smoothly. Learning to fix popped cubes is an important part of your growth and development as a cuber, it is a very useful skill to develop, I have some tutorials on fixing pops on my youtube channel and there are obviously many more online.
