Read review before purchasing extensions!
This game is extremely fun and truly teaches a child or an adult to understand how Gravity affects the steel ball bearings and how bridges work! It also teaches a child how to follow instructions and ultimately, their own imagination. I’m a senior and my grandson is 11. I recommend purchasing the large starter kit first, then decide on these extensions.

Mostly works, but the Gravitrax Scoop works better.
Worked great out of the box, however after using it a dozen times or so it had a hard time staying in the down position as the latch wouldn't catch. I used a knive to give it a "lip" to hold on to and that seemed to help. The Gravitrax Scoop does the same thing..........but much better and works every time. I would recommend getting that instead.
