Five Nights at Freddy's Overview

So basically, Five Nights at Freddy's is a point and click horror game in which the goal of the game is to get through five nights on a night shift in a restaurant titled Freddy Fazbear's Pizza, without getting caught by the animatronics: Freddy Fazbear (Bear), Chica the Chicken (Chicken/Ugly Duckling), Bonnie the Bunny (Bunny), and Foxy the Pirate (Fox at Pirate Cove).

A strategy you could use is checking Pirate Cove frequently so Foxy won't flee and try to get you. (Foxy is the only animatronic that can run physically and get you while the other ones teleport around the map). These characters have a determined pattern which goes as such:

Office = where you are. (You can't move)

Freddy and Chica: Show Stage -> Dining Room -> Restrooms -> Kitchen -> East Hall -> East Hall Corner -> Office.
Bonnie: Show Stage -> Dining Room -> Backstage -> East Hall -> East Hall Corner -> Supply Closet -> Office.
Foxy: Pirate Cove -> East Hall -> Office. (Yes, he skips East Hall Corner).

Hope these tips helped you.
