Day & Night is a game that evolves in step with children's growing skills: Hand-eye coordination and fine motor skills. Ages 3 and up: Visual perception of colors and shapes. In the day everything is bright and clear so the day side of each challenge shows kids all the details of their playing pieces and the shapes needed to create the scene. Ages 4 and up: Visual perception and logical reasoning. At night, when it's dark, kids can only see silhouettes so the night side of each challenge only gives kids the outline of what they have to create.
