GraviTrax – the interactive ball track system from Ravensburger for your mobile or tablet. Use the free app for the GraviTrax ball track system with its free editor to build your very own fantastic tracks, and then roll the balls as you watch from different angles. Try endless new combinations and come up with new ideas to build your tracks. Experience the tracks interactively and follow the balls from a variety of camera angles – including in Virtual Reality if you have the right glasses and a compatible phone.

The GraviTrax ball track system lets you build your own track worlds according to the laws of gravity. Use the construction elements to create a fast-paced course where balls roll to their destination with the help of magnetism, kinetics and gravity. The GraviTrax ball track system makes gravity a fun learning experience which can be extended with countless expansions. Unlimited fun guaranteed! The starter kit and the action-packed expansions are now available in all well-stocked toy shops and online stores.

Great app with one serious but easily fixed flaw

This app is great even if you don’t have any of the physical pieces. However (this is the serious flaw), the music can’t be muted without muting the whole app. I want to hear the noises the UI makes but the music has already gotten on my last nerve.

Also, in the US we say “learned”, not “learnt”. “Learnt” is used outside of the US and Canada. So, devs, after you make it possible to mute the music separately you can update the US and CAN English regionalization files 😀👍

This is a very cool game but I wish I knew what the new parts do.

Can’t believe this is free

Not that you can’t get this system in America... but, it does cost a lot to do so. They literally give you an unlimited number of every piece available and let you go to town! I’ve been playing this for hours with my kids just building away! And it makes me want to buy the actual set even more. Simply amazing
