Check Out These 10 Finalists of the LEGO Ideas Test Lab Fourth Build Challenge.

Since the launch of the LEGO Ideas Test Lab last January, fans of the LEGO Creator 3-in-1 sets took to the Internet their fond affinity for the theme. A sort of a hybrid between the LEGO Ideas and Rebrick platforms, the LEGO Ideas Test Lab seeks to find out the most creative and ingenious use of LEGO’s 3-in-1 sets to come up with what they refer to as a ‘Fourth Build’. The idea is to come up with your own MOC using only the pieces provided in the following 3-in-1 sets: Super Soarer (31042)Green Cruiser (31056)Air Blazer (31057), and Mighty Dinosaurs (31058).

4320 Creator 3in1 Fourth Build

More than 570 entries were submitted by site members from February 1 to March 7, and from this pool, 10 finalists were eventually selected by an expert panel from the LEGO Creator team. The expert panel evaluated each entry in terms of buildability and creativity. Other things that they looked into are how easy the model is built, stability, originality and cleverness, functions, and creative use of LEGO elements. The 10 finalists then went on to the Brick Voting phase where community members will have the chance of voting for their favorite build to come up with the Fan’s Choice Winner.  The Brick Voting stage is currently over and we’re just waiting for the results to be announced.

In case you haven’t seen these impressive entries yet, here are the Top 10 finalists of the LEGO Ideas Test Lab, Fourth Build Challenge, including an entry from LEGO Ideas Maze (21305) creator, Jason Alleman. Jason was even kind enough to share his entry’s building instruction in case you want to re-create it using your own LEGO pieces. Who do you think will emerge as the very first winner of the LEGO Ideas Test Lab Fourth Build Challenge?
