Fans of virtual reality and video games love the amazing LEGO® Hidden Side universe, where physical and digital worlds meet to provide an incredible, single or multiplayer augmented reality (AR) play experience.

This LEGO Hidden Side Mystery Castle (70437) playset combines a buildable LEGO model with an app, so interaction with the model triggers events in a digital world.

Digitally interactive ghost-hunting toy

The mystery castle springs to life when viewed through a smart device with the LEGO Hidden Side AR app. Children then get to explore, solve mysteries, hunt ghosts and battle boss ghost The Maw in an exciting digital world. The possessed castle model also folds out, setting the scene for action-packed role play with the Jack, Parker, Vaughn, Nehmaar Reem and 2 Shadow-Walker minifigures.

An ever-evolving digital play experience

The LEGO Hidden Side universe is set in the fictional town of Newbury, where ghosts haunt people and buildings. The AR play experience is constantly enhanced through new content, characters and special events.
