Review on RoWood Wooden Marble Puzzle Building Puzzles in 3-D Puzzles by Sam Dhungana

Rowood 3D Wooden Marble Run Puzzle Toy Gift for Adults and Teens Girls 14+ DIY Model Kit This was a Christmas present for my 14 year old son. He is very good at putting complex things together. He has been building Lego since he was three years old. There are some very uncomfortable parts, but they send lots of extra parts just in case. He definitely broke a few of them. It is not a difficult toy to play with. You also have to be careful when turning the handle to launch the marble. Making marble work is fun and we've all tried it. I would say it took him around 8 hours over several days. He wants another one so that's a great sign because I showed him because I wanted one (btw I didn't get it :( ), he turned his back on him. My best advice is take your time be careful, if you're frustrated, walk away and do it later (she'll still be there), otherwise you'll likely break into a lot of pieces and won't be able to finish.
