The puzzles in the book should be designed to suit the age group for which it is intended. The level of difficulty should increase gradually, and the puzzles should be challenging yet fun for kids. Use bright and colorful illustrations to make the book visually appealing and attractive to kids. The illustrations should also be relevant to the puzzles. Ensure that the instructions for each puzzle are clear and easy to understand. Provide examples wherever necessary to help kids solve the puzzles.
