The girl Masha, waking up, ran to visit her friend Bear. Together with him, she decided to play the game Sweet Girl and Bear Memory Challenge, which is designed to develop memory and attentiveness. You will join her in this entertainment. A playing field will appear on the screen on which the cards will be located. They will all lie face down. In one move, you can turn over any two cards and examine the images on them. After that, these items will return to their original state. You will need to remember these pictures. Now make a move again. As soon as you find two identical images open the card data at the same time. Then they will disappear from the playing field and you will be given points. Your task is to clear the field of objects as quickly as possible.
