More complex puzzles may require higher levels of problem-solving skills, spatial reasoning, and patience, which may not be suitable for younger children. Additionally, puzzles with small pieces or intricate designs may pose a choking hazard for young children. Age restrictions help ensure that individuals are able to fully enjoy and benefit from the puzzle without frustration or safety concerns. **
