To succeed, simply follow the diagram engraved on one side of the cube! Are you lost? There is a solution! Each engraved diagram corresponds to a level of the inner "disk" of the cube. The first "disk" is located at the top left and the last one at the bottom right. However, be careful, the starting point for the ball is not at the top left corner of the first "disk". A small black square on each level corresponds to a hole in the disk to allow your ball to descend and continue its path towards the finish line!
