Defeat the Troll in this Track Builder™ challenge! With Track Builder™ there's no limit to what can be created, especially now that it's fully brick compatible! YOU are in the driver's seat! Create your own outrageous stunts, experiment with speed and keep challenging yourself to Make it EPIC™! Build and stunt your way through the motorized bridge and build a Troll with bricks! The Hot Wheels® Track Builder™ Troll Bridge Challenge is the ultimate set for igniting their imagination and fueling competitive play. Launch your cars when the motorized bridge arm is mid-way up! Complete an epic jump across the dangerously large gap (and evade whoever is on your tail!). You can launch 2 Hot Wheels® cars through the motorized bridge and see which one conquers one of the 4 suggested challenges. Then move around the bricks and bridge and try to tackle the next challenge. Four sets in one with multiple configurations! Combine with other track and bricks for even more fun! Great gift for kids 5 and older.
