Mystery Castle Reviews

The Brothers Brick
“The Mystery Castle will be a nice addition for anyone looking to add a reasonably priced spooky castle to their collection. It doesn't have the color splash of the Scooby Doo Mystery Mansion, but the inclusion of lots of light blue colors in the transparent pieces and... More stickers keeps it from becoming boring. The astronomy tower in dark tan with its curved roof and large telescope makes for a nice accent to help this castle stand out from its predecessors.”

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.

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.

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.
