Sophia's game is a memory game similar to concentration. It was written specifically for my 3 year old grand daughter. No Ads or in-app purchases. Free to download. Choose from 7 board configurations. The easiest is 4 columns by 2 rows. The hardest is 6 columns by 6 rows. Each board is initialized with animated icons in pairs. Touch two squares to expose the picture. If the pictures match, the two icons are removed. If they do not match, they are turned over and the game goes on. Continue in this manner until all pairs have been found.
