The Minifigure Monsters have taken over! The ultimate indoor LEGO playground invites families to Brick-or-Treat, a frightfully fun Halloween adventure for kids and kids at heart.

From October 1-31, 2026, the LEGO Discovery Center offers brick-tastic Halloween fun with a seasonal twist on everything this unique destination has to offer — and the event is included with admission!

Kids can test their building skills with new Halloween build activities, then let their imaginations run wild at hauntingly cool creative workshops featuring glow-in-the-dark brick builds. Plus, the popular 4D movie, The Great Monster Chase, makes its return — will they help catch the monsters?
