The Carl’s Bubbloid 4x4x5 is a rare and innovative cuboid, designed by the talented puzzle creator Carl Hoff. This unique puzzle combines an irregular 4x4x5 cuboid structure with rounded edges and curved surfaces, creating the signature “bubbloid” look. Despite its unusual shape, it retains classic cuboid mechanics, where different layers rotate independently, combining shape-shifting with layer-based solving. The rounded design not only adds visual appeal but also makes the puzzle comfortable to hold and turn. Carl’s Bubbloid 4x4x5 is both a technical challenge and an aesthetic masterpiece, attracting collectors and twisty puzzle enthusiasts seeking something truly unique.
