3 Days - Zoo Mystery is a nice hidden-object game in which you are a detective who needs to uncover the mystery of the stolen animals in the zoo and recover them in just three days. For this, you will need to collect clues by playing hidden object games, as well as mini games. In every scene you visit, you will find a list of objects that later you need to use to retrieve a clue or a key that leads you to a clue. The objects in the list will appear in the form of images, so it's easy to identify them.
The objects are pretty well conceived though, so you need to look at the scene very carefully. The scenes are not timed, so you can take all the time you need to find the objects. You can also interact with other objects in the scene, which will provide clues or some help. Sadly, the game only includes one mode and one difficulty level, and it offers very simple graphics and sounds. The music is suitable.
All in all, if you like hidden-object games with a detective twist, 3 Days - Zoo Mystery may work for you.
