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.

My son loves these! Secretly, so do I. We work together and build the most complicated tracks we can come up with and then race marbles against each other. Great times!

What's a brothers toy? Its a toy that two brothers can share and play with. Started last Christmas. Made some additions this Christmas. When they get tired of playing, they pack it up and put the box on the shelf. Then they decide that it's time to build something so they do. They experiment and fail, problem solve then succeed. Good toy.

My Nephew loves this so much -it's right up there with lego's top toy in his house hold. I bought him the starter kit last year and was requested to buy the expansion kit's for this year. Great learning toy!!!!!

I had couple of false starts putting the bridge sections together, but, once I figured it out, it was a snap.

The bridges easily break and even if it did not, they take to much speed and are not cool enough to make it worth it.

Mio figlio è un grande appassionato di gravitrax e ha diverse estensioni, questa purtroppo è l’unica che non vale la pena comprare. Gli incastri di plastica che uniscono i pezzi sono troppo fragili e se ne sono rotti diversi non potendo più utilizzare tutti i ponti. Sicuramente un adulto sarebbe stato più delicato nel montarli e smontarli ma è un gioco per bambini dagli 8 anni in su e dovrebbe essere conforme al loro utilizzo.
