Find and close the pictures

In this game you are given a certain number of pictures. All of them are applied to the turning cubes. Some images may be repeated. Your task is to close all the images. There is one condition - if you have closed any picture, then after that you need to find all the same images and close them, and only after that you can proceed to turning over the remaining cubes with other images. If you miss at least one image, and start turning the cubes with another picture, then you will be shown which images you missed and the level will begin to be invited. This is a very exciting game for the development of attention. With seeming simplicity, many levels will be able to pass far from the first time.
