Review on Experience The Thrill With ROKR Marble Explorer Wooden 3D Puzzle Roller Coaster Kit - 260PCS DIY Mechanical Model Educational Toy For All Ages! by Travis Rio

Beautiful puzzle. My teen spends hours building it, keeps her off devices and teaches her about engineering.It’s taking her about 3-4 days to finish it, but she only works on it until it becomes frustrating, then walks away for a while.Each piece is laser cut to perfection! It pops right out, doesn’t get stuck and with minimal sanding.My 6 year old wants to help, and he totally can—if she lets him. It’s like one of those lego sets but with wood, actual mechanics. It’s different in all the good ways.Building itself is fun, but the marble run is great to play with. It really works, and it’s interesting to watch.If you’re looking for a present for a teen, forget video games or clothes. You’ll see a different side of your kid with this puzzle.It says 14+ on the box, but with adult’s help I’d say any school age kid can build it.Directions are marked very clearly, each piece has a number—just be careful with the gears!
