Marble Genius Marble Run Stunts Starter Set: 100 Pieces Total, 14 Action Pieces Including New Patented Trampoline, Includes Free Online App and Full-Color Instruction Booklet, Made for Ages 5 and Up

Purchased for grandson with autism! Provided quality time with dad and satisfaction of accomplishment!

My son is seriously losing his marbles over this. So many hours of creative fun. I was a little disappointed there is nothing dinosaur about it, apparently the colors are Dino colors… but it does not detract from being an awesome marble set. This would have been great for him at a younger age, but feels pretty perfect at 7 and I think we will get some time out of this.

Very pleased with this purchase! Love the diverse action pieces, the new marble trampolines, and the sliders too! It requires few trial and error to line up the jump with the trampolines and the catch basin, however it works almost every time. The only things I would pick up on are the stability and sturdiness, which doesn't stack up to older standards (the Marble Genius Extreme Set we purchased in 2019). The marbles are also a bit dull and could use more variety.Generally, we love this set and are excited to use it more in future marble run projects.

My son loves to build things and this was a great alternative to purchasing more magnets (just wanted to try something different that allowed him to be creative). Some of the tubes can be tricky to put together and it can take a lot of maneuvering to keep them standing once put together.

I loved this Marble thing! I ordered it by accident and it is my Grandson loves it so much! He shows me what he does every time so I will not miss out on anything

My grandsons spend hours playing with Marble Genius Marble Run. There are enough pieces for them to each make their own or they can combine their efforts and practice cooperation. And I get to watch them problem solve and celebrate their creations.

I am no expert on marble runs, but I have bought a few over the years. This one is cooler than the others because you can design it to get airborne and then catch the marble in different catching devices. Having 4 trampoline type devices is too much, at most I could only use one of these and have it work without the marble falling off every time.

all pieces there, fun for toddlers w/adult supervision, until older. Caution: Had 2 marbles shatter with normal play action, so be careful as they can be a choke hazard for small babes.
