Review: Great fidget - Helps keep my problem solving sharp. Works as a great fidget. Arrived quickly. Very well built (I’ve accidentally dropped mine kinda hard a few times already)
Review: Good, if deceptively easy puzzle. - Build quality is fine. Turning is a bit weird, but that's because until you figure it out, you'll commonly try to hold the puzzle on a part that wants to turn. You'll get used to it quickly! The only complaint I have is that it's a LOT easier than it seems; to look at the puzzle, it seems like it's absolutely crazy, but there's basic symmetries that show up that will make it very simple to figure out. I still don't know all the algorithms and can consistently solve it by just fiddling.

## Questions & Answers

**Q: Does this item come with an instruction booklet that helps with solutions?**
A: This item does not come with an instruction booklet or solution guide.  But you can certainly find videos on youtube which provide guidance.

**Q: Is this the same as the gear cube? Besides the fact that it's a ball?**
A: Yes, it is a stickerless shapemod, even though the shape doesnt add any changes to how to solve or move the puzzle, it somehow made it turn better. So yes, it is just the ball-gear cube.

**Q: What do you all get When you buy the gear ball**
A: just the gear ball  in astetically pleasing packaging.

**Q: Do you solve it like a 3x3?**
A: No, while its base structure is identical the gears add a bandaging which changes the way the puzzle is solved.in my opinion it is easier then a regular 3x3 rubiks cube

### ⭐⭐⭐⭐⭐ My kid LOVES it
*by A***N on May 8, 2023*

Pretty cool and unique Rubik's cube variant, but much easier to solve. My kid can't yet solve a 2x2 Rubik's cube, but he can handle this one, and it is fun to spin the gears around
