A 3D puzzle is a three-dimensional model that requires assembly from individual pieces. Unlike traditional flat puzzles, these puzzles create a tangible object, such as a building, vehicle, or animal, once completed. They often come in various materials, including wood, plastic, or cardboard, and can range in complexity from simple designs to intricate structures. These puzzles are popular among both children and adults, as they promote problem-solving skills and spatial awareness. Many 3D puzzles are designed to be educational, helping users learn about architecture, engineering, or geography while having fun. They can be enjoyed solo or as a group activity, making them versatile for different settings.
