The Brothers Brick
“The Mystery Castle will be a nice addition for anyone looking to add a reasonably priced spooky castle to their collection. It doesn't have the color splash of the Scooby Doo Mystery Mansion, but the inclusion of lots of light blue colors in the transparent pieces and... More stickers keeps it from becoming boring. The astronomy tower in dark tan with its curved roof and large telescope makes for a nice accent to help this castle stand out from its predecessors.”

New Elementary
“Overall I enjoyed the build experience, with a couple of minor exceptions where access was a bit limited. The finished model is quite substantial, and even without the accompanying app the Castle provides plenty of scope for ghost-hunting scenarios and play. It also offers... More potential for MOCing with interesting pieces if that is what attracts you to the set and its component parts.”
