LEGO Masters - Episode Guide

In the first episode, 48 pairs are whittled down to just eight final teams through a series of challenges. Next, the eight teams must create a spectacular brick banquet, including an impressive chair that not only looks the part, but also strong enough for presenter Melvin Odoom. The teams must also make at least one supersized masterpiece for the banquet table. The results include a crispy aromatic duck and prawn toast, a hog roast, and a gravity-defying cuppa. Judging the models is a man who knows a thing or two about bricks, The LEGO Group's Matthew Ashton, Vice President of Design. Joining Matthew this time is structural engineer Roma Agrawal, who will be looking at how the seats sit up under scrutiny. Two teams must be eliminated. Who will tower above their opponents, and who will come tumbling down under the pressure?

The search for UK and Ireland's most talented Lego builders continues. This week the teams must step up a gear and make their models move. They have to build a funfair with at least one spectacular supersized mechanical ride, complete with moving parts and characterful stories in miniature form. While an inventive spinning laser ride draws the crowds to one fairground, a sandwich-stealing shark is a pest at another. The judges also throw them a curve ball with their unplanned challenge, where the teams find themselves having to quickly build a vehicle with no time to prepare. But that's not the only surprise in store, as halfway through the challenge the judges give each team a new mode of transport and announce that they must create a hybrid of the two. One team must go home, so who will rise to the challenge and who has laid their very last brick in the Build Room?

Nature is the theme this time as the remaining five teams take their construction skills into the great outdoors. The challenge is to create and install a spectacular brick display for a nature walk that will be transported to a woodland in Essex. From plants, animals and insects to mythical creatures, the teams can create whatever they want, but it must be full of character, wow the judges, and fit seamlessly into the environment. So how do you integrate a Madagascan crocodile into the Essex countryside? And there's a frantic hunt on for a missing chrysalis. There's also a quick-fire round to make as many miniature insects, birds and wild animals in 45 minutes, using no more than 15 bricks. Joining The Lego Group's Matthew Ashton as guest judges is one of the world's leading brick animal artists Sean Kenney, and comedian Bill Bailey.

It's the last stage of the contest. Which team will be crowned Lego Masters 2017? First, the remaining teams face their toughest quick-fire build of the competition and their toughest critics - children. The teams then have just three hours to bring the children's inventive stories to life as brick displays - including a robot with an ostrich head, an alien from the planet Zorg, and a monster who devours a chocolate lake. Next, for the Grand Final, the remaining two teams have two weeks and half a million bricks to make their masterpiece. One team makes a human sculpture while the other createa a mythical world. Both builds are revealed to the public at London's Design Museum; where they are judged by The LEGO Group's Matthew Ashton and celebrity guest judge comedian Dara Ó Briain.

The teams compete to construct a skyscraper and a metre-long bridge that will withstand a weighted dumper truck . This episode's guest is comedian Rob Beckett.

The teams do battle in a drop test to see which model gets smashed up the best. They also build a memorable scene from history. Joining the judges is comedian Paddy McGuinness.

Melvin Odoom welcomes the six remaining teams back to the Build Room. Their first challenge is to build a land and sea animal hybrid. Which team will create the wackiest creature? The teams' next challenge is the biggest yet. So big, in fact, the teams have to head off to a real life golf course to demonstrate their life-size crazy golf holes - complete with putter. Comedian and Lego superfan Chris Ramsey tees off as this episode's celebrity guest judge, joining regulars Matthew Ashton and Fran Scott to decide which teams will make it through to the semi finals.

It's the semi-final. The teams create a bust of comedian Johnny Vegas. Can they capture the essence of Johnny in plastic bricks? They also build a life-size arcade game.

The four teams build a walking-talking robo-pet. There is also a Master Build using as many as half a million bricks. But who will be crowned the winner for 2018? With guest judge Sue Perkins.

Six young builders from previous shows team up with celebrities to do battle in a range of festive challenges, including Rob Beckett, Warwick Davis, Joel Dommett and Alice Perrin

New host Nish Kumar presents a celebrity Christmas special, joined by regular judge Matthew Ashton and Amy Corbett from the US version of the show. The three teams are Taskmaster's Alex Horne and Sophie Duker, Sophie Ellis-Bextor and her two sons, and Scarlett Moffatt with her dad and sister. They must construct a wearable Lego Christmas jumper that can survive star jumps and the magical interior of a snowglobe.
