Just five teams remain in the semi-final, and this week they’re challenged to create a bust of a live model Johnny Vegas. Using the plastic building bricks, the teams must create a sculpture that not only looks like the funnyman, but also express his personality. And he’ll be the one to judge who’s captured him the best. Contestants must also create a playable, life-sized arcade game. Presenter Melvin Odoom and judges Matthew Ashton and Fran Scott will be testing each entry for actual playability.
