The remaining teams are tasked with two challenges of speed and strength. The first is a timed challenge to build a car. In the second, the duos’ technical building skills are put to the test when they must make a visually impressive, yet super-strong bridge. Then, their feats of LEGO® engineering are tested as their creations go through a “stress test."

The remaining contestants are given the opportunity to showcase their creativity when they are tasked with interpreting a story that is read aloud from a book selected just for this competition. Nicole Byer, comedian, actress, writer and host of “Nailed It!,” joins the duos on set as she helps the contestants through a twist that leads to a huge vacation prize.

Special guest Terry Crews joins as the contestants embark on a competition of good vs. evil. Storytelling and creativity are at the forefront as contestants create evil lairs. The episode’s twist involves each team incorporating a “swooshable vehicle,” a handheld creation that is brought to life as contestants fly them around their LEGO® world. One duo will be eliminated, leaving only three teams.

In an epic “Star Wars”-themed episode, Will Arnett and guests BB-8, C-3PO and R2-D2 challenge the remaining contestants to build their own droids and replicate iconic scenes inspired by the beloved film franchise. Only the builds that evoke the most visual creativity and attention to detail will impress the judges enough to move forward.

In the final challenge of the season, the two remaining duos go head-to-head as they create their most epic master builds yet. Eliminated contestants return and loved ones come to the LEGO® MASTERS set to cheer the teams on. Duos are expected to give their all and impress the judges one last time!

The teams are tasked with building an eye-catching float in the first-ever LEGO Day Parade.

Teams put a stunt “minifigure” to the test in an explosive stunt action scene. The duos must think carefully and strategically to craft an immersive build filled with slime, water, glitter and colored dust to create the ultimate action movie moment. Will the hero save the day in an incredible visual spectacle or will the execution fall short of what they imagined?

Structural integrity and beauty come together in the most earth-shattering challenge, as teams build a structure strong enough to withstand an earthquake. Find out which designs perform the best and pass the LEGO-brickter scale rating system.

This week’s challenge is the ultimate test in ingenuity and engineering, as teams will create incredible and wearable hats made entirely of LEGO bricks. Then, teams must model their designs on the LEGO runway, hoping their creations don’t collapse into pieces. Get ready to be inspired by the creativity and resilience.

As the competition heightens, the remaining contestants are expected to raise the stakes and elevate their work – quite literally – when the teams are tasked with building a beautiful structure in mid-air.

In the first challenge, contestants are tasked with building an exact replica of Will Arnett's LEGO Lamborghini all from memory! The team that comes closest to replicating the iconic car will win an advantage in their next challenge. Then, contestants shift gears and enter a Demolition Debry battle, in which each team must build a wild, remote-controlled concept car that will fight it out against the others.
