Product Description

The HelloCube 3x3 Gear Cube Extreme is a different kind of gear cube mechanism. With this version, one of the slice layers is free to move independent of the gears. If you're familiar with the standard 3x3 gear cube, this could be a new challenge!

Our Promise to You

All of our products are guaranteed to be free of defects, or we will replace and reship at no cost to you. Please contact us within 4 weeks (28 days) past the delivery date to report any issues with items you have purchased.

Please note that some new cubes when being used for the first few times may experience what is termed a "pop". This is when one or more parts of a puzzle pop out without any damage actually being done to any of the pieces. This also occurs from time to time during normal usage. Pops are typically not considered a defect if the parts which come off can be reassembled by hand.

The corners on 2x2 puzzles should not be twisted as doing so may snap the piece. Damage caused by corner twisting is not considered to be a defect.

Definitely tougher than the Gear Cube

I specifically bought this puzzle having tried a regular Gear Cube before and finding it too easy.
The Gear Cube Extreme is much more challenging, and the current solution I found requires many turns.

Edit August 2022: I found much easier algorithms, but the puzzle is still interesting compared to the Gear Cube.

-1 star because the stickers are inconsistent with other puzzles. It is almost as though there is a Diansheng-style layer of painted stickers on the puzzle, followed by a layer of very thin transparent resin on top. It does mean there's no such thing as peeling stickers for that puzzle, but I sometimes wonder whether the paint might be a health hazard. Also, it means purple is permanently opposite to yellow, and I speculate that the way the stickers work makes the puzzle more dense.
