The point in this game is to choose 2 squares with the same picture. So, there are any pairs there and your goal is to start detecting them. After you successfully find each of the pairs in each of the photos, the next level is opened for you, but harder and more complicated than the previous. Another thing is the fact that the time is running out so try to be more efficient but in the same time faster. Find the squares and detect them using the mouse. So, let's see are you really good at that.
Use your mouse.
