1. Stop In Your Tracks

The contest designed to push the imagination and creativity of Australia's best LEGO builders returns for a third season, and this season promises to take the competition to a whole new level. Up for grabs is the all new Platinum Brick which will give the winning team immunity from an elimination. To win it, they face a massive first challenge. Teams must create a show stopping piece that will stop a train in its tracks. They have 17 hours to complete their builds.
