Create spectacular tracks by adding Add-on Sets to your Starter Set. Each Add-on has been designed to add a specific level of interest, motion or action to your track. Simply choose which one you would like to add to your Stater Set first, and expand your track in any way you like.
You can make your gravity sphere go faster, slower, go up a level, explode out in different directions down your track, flip over or even loop around. There is no limit to your imagination. Experience the power of gravity!
