Calvin’s 4×4 Green House is actually a nickname for Calvin’s 4x4x4 Inverted Glassy House Cube II which is the official name of the cube. The puzzle is a so-called shape mod, a shape modification of a 4×4. This means that you benefit from what you learned from the regular 4×4 cube. But here you get an extra challenge!
Calvin’s 4×4 Green House
Calvin’s 4×4 Green House is an eye-catching cube in the shape of a house. The house has a “glass roof” in transparent stickerless pieces in a regular 4×4 shape. The body of the house is black with stickers where the pieces have mixed shapes. The puzzle completely changes shape when you scramble it and becomes completely unrecognizable, it is thus a so-called shape shifter. The cube has very good turning quality and is a perfect gift for all cube enthusiasts!
