Find 500 Differences

'Find 500 Differences' delivers exactly what it promises. Even more, since there are actually 104 levels with 5 differences to find on each one, technically making total of 520. Beloved puzzle from newspapers and magazines. Your task is to observe two photos which seem identical and try to find the 5 differences on each level. It's totally the same whether you'll search and click on the left or right image, but, don't just tap randomly on the screen since it will lower your score (although below the one star you can't go).
