Review: Amazing present for my nephew - My nephew really like this present! The only downside, I had to install the app and leave my phone with him, maybe for too long, he was a bit addicted! I think he was more interested in the game than the Lego at the end, but I guess it's ok! Review: This is educational and constructive to have for children - What a great toy to have, very creative and educational for children, my 8 year old spend a lot of time, thinking and reading instructions to build up hid Lego, he has now collected all hidden side Lego. 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! ## Features - Warning:Not suitable for children under 36 months - 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.

The only downside, I had to install the app and leave my phone with him, maybe for too long, he was a bit addicted! I think he was more interested in the game than the Lego at the end, but I guess it's ok! ### ⭐⭐⭐⭐⭐ This is educational and constructive to have for children *by D***Y on 17 December 2019* What a great toy to have, very creative and educational for children, my 8 year old spend a lot of time, thinking and reading instructions to build up hid Lego, he has now collected all hidden side Lego. 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! ### ⭐⭐⭐⭐⭐ Amazing fun with or without the app *by D***G on 10 November 2019* I was so pleased to be able to review a Lego set. My children are obsessed with Lego and don't play with a great deal else these days so having a brand new set scored me lots of Dad points. The set itself is well-priced for what you get. There's a lot of detail and it looks pretty cool. My son loved building it and has now decided he'd like to ask Santa for some of the other Hidden Side sets. He usually only asks for Ninjago, Star Wars, or Marvel sets so this must be good to make his wishlist. The only downside is the app. It's great but make sure your or your child's device is compatible if you want to use the app with it. We struggled to get the app at first because it was released later than expected. When the app was released it we discovered that our son couldn't download it to his iPad because his model is a few years old now and isn't compatible. ## Frequently Bought Together - LEGO Hidden Side 70420 Graveyard Mystery Construction Set, AR Games app, Toys for 7 Years Old Boys and Girls, Interactive Augmented Reality Ghost Playset with 4 minifigures - LEGO Hidden Side 70418 J.B.’s Ghost Lab Building Set, AR Games App, Toys for 7 Years Old Boys and Girls, Interactive Augmented Reality Playset with 4 minifigures --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/143560707-lego-hidden-side-70420-graveyard-mystery-construction-set-ar-games](https://www.desertcart.sg/products/143560707-lego-hidden-side-70420-graveyard-mystery-construction-set-ar-games) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-08-12*
