On the exterior, yes, it is a 3x3x6; however, they kind of "cheated" their way there. the middle layer is similar to a middle layer of a 3x3, one "layer" is 2 layers (similar from the 3x3x5), and the last "layer" is 3 layers (like their 3x3x7). It is still fun to solve; however, it is not what I was expecting from a 3x3x6. I would recommend the Witeden 3x3x6 over this.
