DIY Gamer's Gear Ball Challenge Build Kit by ROBOTIME LLC

Details & care

Part build kit, part game-night legend, this hands-on puzzle is where old-school arcade vibes meet modern-day marble run mayhem for a fully interactive tabletop challenge. Your mission? Assemble the machine, then guide your metal ball through high-speed stages using a system of knobs, levers, and switches—no screens, no batteries, just gears, gravity, and glorious gameplay. Includes 653 precision-cut pieces to build a working mechanical marble run with interactive controls. Shaped like a retro-style game controller for a nostalgic-meets-modern look. Race your marble through six dynamic challenges using knobs, levers, and mechanical buttons. Features include a sky track loop, jump ramp, separator wheel, high-speed conveyor, and ejection cabin. Celebrate a successful run with a rising flag and the ding of a copper victory bell. Great for hobbyists, families, STEM learners, and anyone who loves hands-on fun. Assembled size: 11.6"L x 7.7"W x 8.1"H. Build time averages five hours. Made in China.
