10 Days Under The Sea is an underwater hidden object game. Despite having a fairly difficult hidden object side, there was a more interesting side that involved taking pictures of fish. Unfortunately, that part is only interesting for a few minutes. Then it seems like it's the same fish swimming past. As for the hidden object side, it was semi-difficult because some of the objects are set into the background. This means that they aren't seen as easily as the objects in the forefront. The background objects have a bluish tinge to them, making them hard to see. Honestly, there are much better hidden object games I'd rather play.
