Fully-functional cuboid differs from classic 2x3x3 in that it allows to rotate up and down layers after R, L, F, B, M or S moves. Also, under certain conditions, hidden E-layer can be twisted.
Second version of cuboid a little easier, because it haven't any restrictions, and all layers here are turnable. While first version has blocked U and D sides.
