Our App is a game with small emoticons and matching expressions. Each time there are 12 pairs of emoticons appearing. Click on the square to turn the square over. If the expression image of the double-clicking on the flip is the same, then the two squares disappear and add 80 points. If the expressions of successive clicks are different, 60 points will be deducted. Lets challenge the blocks to see if it is the same difficulty, who can get a higher score.
