What’s Diff 1, part of an educational game series by MyFirstApp.com, focuses on enhancing children's cognitive, language, and visual perception skills, particularly visual differentiation. Designed for kids aged 3 and above, the game challenges players to identify the odd image among a set of four based on bold visual differences like color or placement.

Players encounter varying levels of difficulty in What’s Diff 1, 2, and 3, each tailored for different age groups, with more complex visual and conceptual differences as the levels progress. The game encourages interactive play by prompting children to drag the odd image to a blank square, fostering cognitive development in an engaging way.
