Review on 🏰 Bepuzzled Deluxe 3D Crystal Puzzle - Castle, Clear - Engaging brain teaser that challenges skills and imagination, ideal for Ages 12+". by James Broome

I recommend this game if you want to kill time by solving a difficult problem. Just note that you may get stuck a few times as many of the pieces have the same cuts and appear flush at first even though they aren't in the right place. Eventually I felt like I had completed the puzzle even though I had an extra piece because there were no obvious gaps. Upon closer inspection I found the error and was able to use all the pieces to complete. So if you think you're missing puzzle pieces, have extras and/or don't need them, do a little more research before writing off the puzzle as defective.
