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.

jumper jumps to soon
My son had the jumper for not even 12 hours and it won't work right already. When the marble is rolling down the track, the shacking of the track triggers the release on the jump mechanize, and it jump to soon. This looks like a design flaw. It could probably be redesigned to work but the way it is make now it won't work right will be sending it back.
