This new wooden marble run can be built with 294 pieces and 10 marbles, resulting in a pretty cool end product. It features a crank that uses large gears to move marbles up to the top of the machine, where they then roll down through different channels.

Unlike other wood puzzles, this one has a distinct black-grey appearance, with a metal nameplate and acrylic pieces to make the finished product more visually interesting and allow the balls to be seen in action more clearly.

The great instruction booklet, with large and detailed pictures, makes it easy to identify the parts and understand the assembly process. There is also a spare parts sheet in case any critical pieces are broken during assembly. Customers can contact the company anytime for assistance.

This marble run model is a great alternative to traditional jigsaw puzzles, as it is more advanced. It can be placed on a bookshelf, and your friends will undoubtedly be intrigued and want a demonstration.

This STEM puzzle would make an outstanding Christmas or birthday gift for those who love working with wood and enjoy a challenge. It will take around 7 hours of focused assembly to complete the project properly, making it suitable not only for teenagers but for anyone who appreciates a rewarding building experience.
