Smart Games Day and Night Puzzle is a fun filled game of logic with colours, shapes and silhouettes that evolves in step with your child's growing and developing skills. At night, when it’s dark, you can only see silhouettes, so the night side of each challenge only gives you the outline of what you have to create. 24 day and 24 night challenges. Just as night follows day, the day challenges (1 to 24) provide a great start that gradually builds up to the more advanced night challenges (25 to 48). This makes Day and Night an educational game for children aged from 24 months to 5 years.
