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.

Great Cuboid

This is a really fun puzzle. It was a little stiff out of the box, but broke in after a couple solves. Solving this puzzle is a lot of fun. It requires out of the box thinking, some intuitive parts, some algorithmic parts. But it is short enough not to get tiring.

It solves exactly like the pillowed 2x4x6, but this one looks much better.

it's great fun but...

the cube is really fun to solve and is quite the challenge, but the turn is not the best it feels like it will explode at all times

Erin A. (United States)

Exactly as expected and arrived quickly. Thank you!

Like No Other Cuboid

This particular set of proportions is, in ways, like and unlike other cuboids. It's like them in that most of the usual techniques will work, but it's a broad departure in at least one way - there's a parity situation on here I've never seen anywhere on anything else. Be warned, but enjoy a serious challenge.
