Is it a brainteaser, a building project, or modern art? How about all of the above? This 3D marble run cube is no ordinary puzzle. Designed for teens on up, it invites builders to click together 217 laser-cut birchwood pieces into a fully functional marble maze packed with more than 30 feet of twists, turns, ramps, rails, drops, and logic-testing pathways. Once built, the fun is just beginning. Enclosed in a sleek acrylic display case, the cube becomes an interactive maze you can tilt and turn to guide the marble through 150 unique obstacles. Includes 217 precision-cut birchwood pieces, plus a marble, sandpaper, display stand, and acrylic enclosure. 8" x 8" cube design with over 30 feet of track and 150+ obstacles to conquer. Assembly time is 8–12 hours—no tools or glue required. Clear acrylic housing lets you view and play the maze while containing the marble inside. Carved directional arrows guide your progress through ramps, stairs, rings, and drops. Ages 14+. Made in Ohio.
