This Hidden Side set brings augmented reality into your LEGO build, so you can scan your creation with a phone or tablet to unlock digital ghost-hunting adventures. You get a physical set to build and display, plus an interactive layer that makes the experience way more immersive than just playing with plastic bricks alone. It's perfect if you want something that blends the tactile fun of LEGO with modern tech, or if you're into spooky themes and want a build that does more than just sit on a shelf.
