This awesome 99-piece wooden set contains everything you need to construct the ultimate marble run! It's especially fun if you let a lot of marbles run through your Quadrilla marble run at the same time. Watch them race against each other through the many different paths of your design.
Another cool feature of Quadrilla marble runs is the fact that you can see the marbles on their paths all the time. You can also stop them or change their directions. The Quadrilla Twist and Rail Set opens next to endless possibilities to learn about the 3 dimensions and to think in 3-D!
From very simple to highly complex - only your and your child's imagination and creativity set the limits to what you can create with Quadrilla!
