Ravensburger's interactive ball track system.
Create even more different ball tracks! With this set you can expand your ball track from the Starter Set even further. Just combine the extra floor plates and other building elements and see how complex you can make your ball track! How many detours does your bullet take to reach the finish line?
With the numerous expansion sets such as this Building set, freely building and constructing the interactive ball track system GraviTrax becomes more interesting and exciting every time! More possibilities - more fun! More information at www.gravitrax.com
