This is great for kids, adults, architects, engineers...you name the person, they will enjoy building a contraption that steers a marble from top to bottom.
The simplicity of this game takes you back to the days when a basic toy could provide unlimited fun. This pack of blocks provides the tools you need to build an unlimited number of tower variations. Build to your heart's content, take advantage of angles, but always respect gravity!
Of course, since there are small pieces, this is not for small children.
