Frequently asked questions

Are GraviTrax sets compatible with each other?

Yes. GraviTrax starter sets and expansions use the same system, so you can add bridges, lifters and other elements to any starter set. GraviTrax Junior is a separate, simpler range for younger children.

Are marble runs safe for young children?

Marbles are a choking hazard, so standard marble runs are labelled for ages 3 and up and should be used with supervision. Some toddler runs use large balls instead of marbles, and the age is on every listing.

Do the wooden ROKR and UGEARS marble runs need batteries?

Some are hand-cranked and others have a small motor, which needs batteries. The listing says which. These kits are built as 3D puzzles and are aimed at teenagers and adults.
