Brainstring Puzzle Ball Avançado

Picked this up to keep my hands busy during calls, and the clear outer body makes it oddly satisfying to watch the strings shift around. The 100% symmetry really forces you to think differently than most puzzles I've tried.

I love how the strings are fully interchangeable, so I can rearrange them into new patterns whenever I want. It starts simple but gets seriously tricky once you start mixing it up, which makes it a great brain workout. The symmetry is really satisfying when you finally solve it.

The clear outer shell is perfect for watching the strings twist as you work, and the 100% symmetry means every angle feels fair. I've spent three evenings on it and it's still not solved, which is exactly the challenge I wanted.
