During lockdown, many of us turned to puzzles and construction toys as a shared activity that we worked on together over time – and it reignited a forgotten passion. For those who like to create in 3D, GraviTrax may just be the answer to the coming long summer days spent together while school is out and work takes a back seat.

This is your chance to win one of five GraviTrax starter sets worth $119.95 each,  so you can get the ball rolling!

What is GraviTrax?

An innovative marble run STEM toy designed for curious types aged 8 and up, the GraviTrax interactive track system has high quality components and allows you to design and build your own racetrack and experiment with gravity, magnetism and kinetics to propel your ball to the finish!

Each set comes with clear instructions to get you rolling, but that’s just the start.  Once you have the hang of things, you’re off! Design, create and build to your heart’s content, with no limits except for your own imagination!

With a variety of tiles, levels, tracks and features, you can control the speed of each ball. The open-ended building concept offers infinite possibilities to design a different track every time – and the track can be endlessly extended with various add-ins for truly rewarding building and racing fun.

Playing and building with GraviTrax develops spatial reasoning and planning skills. Plus, it’s just plain good old fun to see how big, how intricate and how challenging a marble run can be when you take it to the next level.

Just what can you do with GraviTrax?

The limit really is your own imagination and a bit of time.  Check out what others have done:

Get ready for racing fun!

The GraviTrax Starter Set is the set that really gets the ball rolling!  With over 100 pieces and 18 different construction elements. It includes everything you need to begin building your own action-packed track systems.

Discover how the laws of physics effect the track your ball takes with curves, crosses, freefalls and even a cannon. Experiment using different heights and angles to control the speed of the ball. The included tasks and construction plans introduce you to the world of GraviTrax. Or let your creativity take over and begin constructing your own track designs from scratch.

How long can you keep the marbles going? Can you beat your own record?

Expansion Packs

Once you’ve caught the GraviTrax bug, you’re going to want to challenge yourselves more, make things taller, faster, more complicated.  And that’s where the expansion packs come in.  Each different expansion pack means you can add in bridges, tunnels, add in height, breadth, a volcano to power your ball along, or loops, and flips, and hammers.

Each expansion pack lets you extend your track system by combining the additional components with your GraviTrax Starter Set – so you can build even bigger marble track worlds!

There are big expansion packs, and smaller more specialised packs.  So, once you have a GraviTrax fan in the family, you are set for Christmas and birthday gifts from then on.

For ages 8 and up, GraviTrax is available at Target, Toyworld, David Jones, Amazon, QBD Books and all other good toy stores and specialty gaming stores.
