Product Description

The Carl's Bubbloid 5x5x4 is a shape-preserving 5x5x4 corner-turning cuboid developed by Carl Hoff, David Ang, and Calvin's Puzzles. It has a very sturdy, substantial feel, and it features the Calvin's and Carl Logo.

Please be advised that the puzzle as it is shipped from the manufacturer does not have much corner-cutting ability, although it does turn well when it is aligned properly. The manufacturer has noted that removing the springs from the corners will improve the corner-cutting on this puzzle.

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.

I Adore this puzzle

This moves a lot like a Redi type puzzle, with radial turns.
I did have an issue with popping and very loose pieces. This eventually led to one corner falling apart, then the side and eventually the entire cube pretty much was reassembled.
My cube has been put back together and it works really well.
I just wonder what caused so many pieces to be so loose OOTB.
Regardless, I think that this puzzle is great and man, does it look fantastic.

I purchased both the 5x5x4 and the 4x4x5. Both popped after turning for a short time. I've reassembled them and adjusted the tension several times. However, I can't get past a scramble and a few turns before they pop again. The idea of the puzzle is nice, but the execution is so poor that this cube isn't usable. Also, several stickers were pealing off out of the box. Considering the price point, this isn't acceptable.

Good puzzle but very hard to turn at first.

A very interesting puzzle to solve. I had difficulty at first getting the puzzle to turn but then after taking it apart and putting it back together, I managed to figure out how to get it to work.
