GraviTrax: Trax Expansion Set | Enhance Your Marble Run Experience | STEM Toy for Kids Ages 8 and Up | Compatible with All GraviTrax Systems | Ranked No.1 Marble Run System in The U.S

This toy is well made and has great value for thinking and problem solving. It kept my kids ages 6-10 entertained for hours. Great STEM toy! Learning is happening as they play.

These kits are great!! Daughter got one a few years back for Christmas, we kinda forgot about it. Till one day we were looking for something to do, and refund it! OMG this is so much fun, and helps learn. So as it sits now, we've boght meant of these expansion kits.

Nephew was so stoked to receive this for his bday. I got him the starter set 4 years ago for Christmas and he still loves to add and build with it.

This has been much fun and educational for our 7 year old granddaughter. Much better than her old marble machine. Gravitrax makes us think about physics and momentum.

Seemed cool really wish I didn't spend close to $200 on the set . It's been played with once

Sensacional juego para estimular la creatividad y ademas muy entretenido con bastantes opciones. Nos costó un poco entender el manual pero despues de un rato, es muy facil hasta mi hija de 9 años pudo realizar los ejemplos que vienen en el manual.

Amazing and gives hours of fun. I bought it for my 4 years old nephew although it is for 8 years. He head trouble to follow the instrauctions so he builds from his imagination with the help of adults and loves it. I guess at 8 years old he will enjoy even more.

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.

Great expansion

Es un gran producto, excelente complemento para Gravitrax Starter

Expensive for what it is and needs a lot of additional boxes to keep the grandson happy

my kid loves these expansion packs to gravitrax, and this was no dispointment either

Les boites Gravitrax sont vraiment bien. Mes enfants y ont beaucoup jouer et continuent encore d'y jouer de temps en temps. ça permet d'inventer de nombreux circuit de billes, il y a plein de petits éléments différents inclus ou à acheter en option qui permette des mouvements originaux des billes. Très bon concept, éléments en plastique de bonne qualité. Bien jouer sur un sol dur/plat sinon, tout ne fonctionne pas comme il le faudrait.
