It's a rectangular parallelepiped that's so simple that it looks like a speaker at first glance. The size of the main body is 151 mm in length x 151 mm in width x 301 mm in height.

It is a game to move from the stage composed of various panels so as not to drop the rectangular parallelepiped and drop it in the hole of the goal. In all 33 stages, I use my head anyway.
