And the advantage to have is to be able to use your iPad to reveal the ghosts on the hidden side Lego. With all the collection we didn’t see my son for 3 weeks in the evening cos he was busy building his lego! Review: A perfect graveyard of Lego - This is my favorite Lego Hidden Side set. It's not the most expensive but I'm admired how efficiently Lego designers place all necessary things (grave, fence, small house and tree) to recreate atmosphere of a real graveyard! ## Features - This Graveyard Mystery features a twisting tombstone statue, grave that opens and a haunted tree with posable arms. - Play out exciting ghost-hunting adventures that combine physical LEGO models with an interactive augmented reality play experience - Download the Hidden Side app, scan the model with a phone to bring the AR world to life, while playing the ghost-haunting adventures - This building set can be played with right out of the box, but for a full experience, a tablet/mobile phone is required (not included) - For all the grave mysteries the app is compatible with selected iOS/Android/mobile devices.
