Eight teams have 15 hours to build a 'whole new world' to win not only the famous Golden Brick, giving immunity, but the Flash Jordy Brick, where they can use season one's famous Jordy as their runner to the Brick Pit.

The teams have 10 hours to make a showstopping Hero Shot, one that looks like the ultimate moment in a movie. They must pick a story that will explode using their four elements: chalk, water, glitter and slime.

A double-header challenge sees the remaining teams build a tower as tall as they can in two hours. Then, in one of the hardest builds so far, they must create magic from one hanging brick - a careful measure of weight and balance.

In a test of their engineering skills, the six teams have to build a structure that can withstand increasing shake factors. The team that survives the highest shake factor will win immunity.

The third elimination hangs over the teams' heads as they are challenged with building a 3D art piece out of Lego. With one team safe with immunity, four teams go head-to-head to create incredible and beautiful 3D Lego art.

In another elimination, the teams face two challenges. The first must be a story that lives above and below their tables, essentially telling two stories. The two teams with the lowest scores then battle it out in a Retro Rebuild.

The ultimate challenge comes to life when the contestants are blown away to discover it's all about Star Wars! Not only do they get to build their favourite ships, but are thrilled when a new Star Wars LEGO Brick Pit is revealed.

Another elimination sees the contestants have to make extraordinary builds that not only look amazing but can go underwater. Does LEGO sink or float? We'll find out

In the penultimate episode, teams face two challenges. The first one sees them only able to use pieces from a smashed LEGO Harley-Davidson. In the second challenge, they must create a building that works in both day and night.

The final episode is here and it's down to our final three teams to impress not only Brickman (and host Hamish) but hundreds of kids, parents, and LEGO fans to find out who will be the ultimate LEGO Master.
