ThinkingKids: Match WorldTHIS IS NOT JUST ANOTHER MEMORY GAME. THIS GAME IS ESPECIALLY PREPARED FOR SMALL CHILDREN.It has very simple user interface and does not need any special instructions how to play so your child can start playing right away.Game includes five themes which children will enjoy: Africa, Farm, Fruit, Sport and Vehicles. It keeps score and time for current game so that at the end of the game you can look and see how good your child played but it does not remember high score or best time, because it's irrelevant. This game is for small children for having fun and also training their brains!MY CHILDREN ARE 2 AND A HALF AND 4 YEARS OLD AND THEY ARE PLAYING IT ALL THE TIME! I JUST GAVE THEM THE PHONE AND THEY KNEW WHAT TO DO IN A SECOND. I was really surprised that my younger child (2 and a half years old) knew how to play in a second and how he was becoming better every time he played.And remember it's not just fun for your child it's educational too!
