In this two-hour Season 3 finale episode "Water Works; Finale: Master Build," the semi-finalists have 10 hours to incorporate a fountain that uses water to create movement within their build. The three top teams move on to the finale where they get 24 hours to build their best creation possible – featuring the first sets they built as kids to celebrate 90 years of LEGO. The duo with the most impressive build wins $100,000, the Master Builder title, and trophy, and gets their creation displayed at LEGOLAND New York.
