Each track unhooks and snaps into place for super simple set-up, then easily collapses for convenience storage. The cage is adjustable and can be raised or lowered depending on the desired level of competition - a series of point panels along the trajectory adds to the excitement of the challenge. Hot Wheels® Loop & Launch™ Track Set takes competition to new heights as cars race to a winner's cage that can reach up to two feet in the air! Vehicles speed through a helix loop then launch toward the looming cage that snaps closed when a car reaches it.
