‘What’s the Difference?’ is a visual based game to help children to develop their visual discrimination and problem solving skills. The game has 12 sets, each having 4 similar picture cards with an added element from one picture to next picture. The child is required to carefully observe all four cards of a set one-by-one and identify the added object with reference to the previous card. This way, children develop their observation and logical thinking skills while improving their concentration and visual discrimination skills.
