When photo pairs appear, locate five differences between each pair (such as an extra object or something of a different color)
If You can find where a difference is, touch HINT.
Time penalities for wrong touches. This is a game that I played in an arcade, and now I'm working on simulating it on My page. Currently, their are 9 pairs of photos each with 5 differences, the first one is below, so see if You can spot the differences!
