Celebrity Contestants Robin Thicke, Finesse Mitchell, Leslie Jordan, and Cheryl Hines team up with former LEGO Masters contestants to spread holiday cheer by competing in challenges to win $10,000 for a charity of their choice. The teams must build Santa a new sleigh that looks great and is tough enough to span across two chimneys filled with heavy holiday gifts.
Teams of two LEGO enthusiasts go head-to-head, with infinite possibilities and an unlimited supply of LEGO bricks. Throughout the competition, host Will Arnett and expert judges encourage the amateur builders, introduce incredible challenges and put the creations to the test. The competing pairs who impress the judges the most progress to the next round, until the finale, during which the top teams face off for a cash prize, the ultimate LEGO trophy and the grand title of LEGO Master.
