Mysterious Castle. Everything you need to know about the set.
Fans of VR experiences and video games will love the fascinating LEGO® Hidden Side™ universe, where the real and digital play worlds merge into an incredible AR experience – in single-player or multiplayer mode. The LEGO® Hidden Side™ set "Mysterious Castle" (70437) combines a LEGO® building model with an app, so that interacting with the model triggers events in a digital play world.
Interactive ghost-hunting toy
The mysterious castle comes to life when viewed through a smartphone or tablet with the LEGO® Hidden Side™ AR app. Children can then explore this exciting digital play world, uncover secrets, hunt ghosts and take on the ghost boss The Maw. The ghost castle model can be unfolded to serve as a backdrop for action-packed role play with Jack, Parker, Vaughn, Nehmaar Reem and 2 Shadow Runners, who are included in the set as minifigures.
A constantly evolving digital play experience
The LEGO® Hidden Side™ universe is set in the fictional town of Newbury, where people and buildings are haunted by ghosts. The AR experience is constantly enhanced with new content, ghosts, characters and special events.
