Millennium Falcon
857 pieces
Labeled super challenging but much, much harder. This is the hardest one I own. All the others have symmetrical patterns to follow. This one doesn’t so it’s extremely difficult to organize or even know where to start. It also has hidden pieces inside. Also, it’s the only puzzle that has a bottom view as well. You can actually hang it from the ceiling. Good thing it comes with assembly instructions!
My husband, son and I spent six hours just today getting it done. It’s a beast!
