Set the gears in motion with this clever wood-and-acrylic puzzle. Your goal is to manipulate the spinners—each with carefully placed missing notches—to synchronize two clock faces perfectly. Precision and patience are required to align the clocks and set them to 11:55. A compact yet challenging mechanical puzzle, it’s perfect for fans of sequential problem-solving and hands-on brainteasers.
