For the first challenge the teams build their own dream amusement park. For the second challenge the teams are paired up, with one team building a superhero creation and the other team building a supervillain creation.

The teams build a model that is then destroyed either by an explosion, getting hit with a baseball bat or slammed into a wall on a sled. For the next challenge the teams see which of their bridges can hold the most weight.

The teams are given ten hours to create a building, they are then given an additional three hours to add a monster attacking their buildings. For the second challenge the teams must create the other half of everyday objects.

The four remaining teams are each given a period of history that they must recreate in Lego form. For the grand finale the teams have 24 hours to build whatever they want.
