This game will allow you to test your attentiveness. All you need to do is to find differences between seemingly identical images. At first glance, the two pictures are the same. But if you scan them properly and study them inch by inch, you will surely find some tiny differences. If you really feel you get stuck, use a hint to continue. Some of the levels will need all your agility as the differences are really hard to find. There are plenty of cool levels to enjoy and forget about everything else around you.
