Dude...serious...if you have 4 left...its always the first or second time right. Without tapping 2 at same time. Open right top one...then the one next to it. If it doenst match (turtle and coral), then open a 3rd different one you didnt open before. It wil ALWAYS be one of the two pictures that you selected before (turtle OR coral). There are no other pictures left. That way you can always choose the right one, coz you already know what the pictures are underneath it.
