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.
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.
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.
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.
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 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 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. Classroom activities: Explain why the winning towers were so strong? Which design could be used in the real world? Do some research on buildings in countries where earthquakes occur. How do they make their buildings withstand shaking? Design your own earthquake proof tower. Test your design with Lego or other materials.
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 the first elimination, teams must create a classic fairy tale scene. They will have 12 hours to complete a fairy story that is recognisable and impressive. For one duo, the chance to be this season's Lego Masters slips away.
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.
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. Which team do you think showed the most skill and creativity? Design your own world, label the design and list the materials needed to make your world.
Three teams battle it out in the grand finale. With 28 hours to build, they can now create their ultimate masterpiece. Judged by public vote, Brickman and a top Lego designer.
The four remaining teams each contribute to a Time Train diorama built in 16 hours. From the Wild West, the Future, Prehistoric and Medieval Times, this challenge will mark the end of one team's journey and reveal our grand finalists.
Teams must duplicate the classic DeLorean car from Back to the Future - the real thing present for reference. Next, they re-create an iconic moment in cinema in a vignette on their tables, with the least impressive team saying farewell.
Imaginations are let loose in this challenge where teams must create an evil lair for a supervillain Minifigure in 13 hours, including a vehicle. The least impressive villain world will ultimately send its makers home.
In a test of their engineering skills, teams must construct a bridge across a 2m canyon with no centre support; the winning structure will be the one to withstand the most weight. With 10 hours on the clock, the race is on.
Teams must break apart Brickman's parrot to create something original in four hours. They'll then build an impressive three-storey apartment in 10 hours, stacking on top of each other's.
In the first elimination, teams must turn everyday items that have been cut in half from normal to incredible. A bike, a typewriter, a TV and a violin must be morphed into something completely new using only Lego.
