Lego Masters (Channel 4/HD | 8:00pm to 9:00pm | Thursday 31st August 2017)

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?
