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!

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!

Lots
Excellent set, lots interactive parts and the app is a great addition to this Lego series. My son and I bother enjoyed this over Christmas. I would estimate that it took around an hour for us to build, you could probably do it in less time working solo... lol

Disappointing due to technical error
The Lego set itself is amazing, good value, you get a lot in it.However, I brought this as a gift, and partly brought this for the Hidden features that involve the use of a phone app, to my horror (no pun intended) the "Hidden Side" app doesn't work on Android phones (at time of writing this review), hopefully Lego will fix this problem.

Amazing fun with or without the app
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.

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!

Brilliant fun!
Great lego set. Built it with my 8 year old. We couldn't wait to try the app and we weren't disappointed. It's brilliant.

Great looking set
Bought for Christmas so no child review as yet but it looks great, packaging in very good condition. I think I will have a very happy daughter.
