LEGO Masters

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
