The Unique Fish

The Unique Fish asks a question that sounds easy and rarely is. Each screen is a photo crowded with fish, nearly all of them alike, and somewhere in the shoal is one individual that is different. Your task is to find that one-of-a-kind swimmer.

Fish are well suited to this sort of puzzle. In nature many species school precisely because a dense group of identical bodies makes it hard for a predator to single out one target, and the same effect works against you here. Your eye wants to see a single silvery mass, while the game wants you to notice the exception.

The description calls it a photo hunt that tests your keen eye for detail, and that is a fair summary. There is no story or management layer, just picture after picture of fish and the small thrill of spotting the odd one. It is a calm, focused game that rewards slowing down and looking properly.

1. Look over the photo of the school of fish.
2. Compare shapes, colours and markings across the group.
3. Find the one fish that does not match.
4. Click it and move on to the next photo.

Defocus slightly and look at the whole image instead of fish by fish. A mismatched colour or direction often pops out of the pattern faster that way.
