Marble Run

This comes in various names, such as rolling ball sculpture and ball run. Playing it doesn’t require that much effort, especially after assembling. All you have to do is put the marble at the top of a designated hole and watch it roll down the course. In its early years, the course was made with sculpted wood and the duration of the ball rolling was considerably short.

Now, it is more interactive as you can play it with friends and family. It usually comes in colorful puzzles, is made with plastic, and is highly customizable. Just like KNex, building the course is an intricate process so having extra hands is suggested. However, if your patience is to a commendable degree, this one’s for you.
