- September 30th, 2020Average rating5out of 5 stars5.0Fun family activityJuliet35 |I would recommend this to a friend!Legos are a favorite past time at my house. From picking our next set, to working as a team to build it. My kids are always excited when we complete our LEGO set. What makes this Mystery Castle even funnier is the interactive ability with a mobile device. With larger sets like this one, it takes us at least three days to build. My kids do most of the building and I help with the hard parts. For most of the build my 10 and 8 year old could snap the pieces together, an adult had to assist a couple of times. I really appreciate how the bags are labeled with numbers and that it’s broken up into separate stages. At the end of every bag you always have spare pieces, which is a great idea, incase one of the smaller pieces gets misplaced. I’m always impressed with the instructions. This set was larger and the booklet was easy to follow. Both my kids love being able to read the easy step by step pages. Having detailed pictures is great! My children not only enjoyed building this castle, but also bringing it to life. We used the app on my phone to scan the build with the camera. It’s super neat how you can fight ghosts and see them flying around on your device. It’s an easy game and makes legos even more fun. You do need a newer device to play, so an older phone or tablet won’t work. I have an iPhone 7 which can play the interactive game. My kids and I are looking forward to more LEGO Hidden Side builds and can’t wait to put together our next set.Play ExperienceAverage rating5out of 5 stars5.0Level of DifficultyAverage rating4out of 5 stars4.0Value for MoneyAverage rating4out of 5 stars4.0Was this helpful?55Mystery Castle
- October 1st, 2020Average rating5out of 5 stars5.0Lots of funI would recommend this to a friend!The Lego Hidden Side Mystery Castle was so much fun to build. My daughter spent the whole day off and on building the castle. The instructions are detailed and the pieces are split up into separate packaging to make it easier to organize and build. This was a great indoor activity to keep kids busy and at the same time learning about how structures work. As I've come to expect from Lego, the pieces all fit perfectly and there were some extras of the smaller pieces just in case they got misplaced. Building it was not too challenging especially for a teen, but may be a little more challenging for kids under 10. However, that being said, it's a great activity that teaches a lot about building in general. Another thing I liked was the details in the set. From the miniature piano to the "stained glass" windows and moving parts within the set, there were so many details that made this set worth every penny. My absolute favorite part about the castle though was the innovative technology that was built in. I love that there was an app to download after you build the set and you can actually play games and "catch ghosts" virtually. So not only does it give kids something to do while they build, but becomes a long term activity as well. What's also great is that this isn't just limited to kids; it's a great model to build for anyone and looks great as a show piece in the home as well. I am so very impressed with the Mystery Castle and highly recommend it to anyone looking for an activity that is fun, innovative and imaginative.Play ExperienceAverage rating5out of 5 stars5.0Level of DifficultyAverage rating3out of 5 stars3.0Value for MoneyAverage rating5out of 5 stars5.0Was this helpful?55Mystery Castle

Make no mistake, it's a good addition to my collection. I just don't think it's worth $100. I can't wait to get the rest of the new line though.Play ExperienceAverage rating4out of 5 stars4.0Value for MoneyAverage rating4out of 5 stars4.0Build Time: 8 hrsBuilding Experience: Expert LEGO builderWas this helpful?55Mystery Castle
