This is a custom puzzle made from a Nintendo ten billion barrel. The horizontal movements are like in the original, but the black inner axes were shortened so there is no longer a vertical movement. One hole in capping layer are left open. The others are filled.
With the help of the single hole and with gravity the puzzle can almost be played like one of the varikon series, except that two layers of marbles are moved at once.
