1st Night

The 1st Night of FNAF:GME is the easiest of the five. Phone Guy introduces the mechanics, and the player is presented with the Office, the Monitor, the Light, and the Door.

Strategy
Watch the cameras to make sure Bonnie and Chica stay away from the Office. If Bonnie is at the end of the Hallway, by the time you put down your Monitor, Bonnie will be at the door. Close the door immediately, as you only have a few seconds to react. The same with Chica. Use the camera only for a few seconds, as it wastes power significantly. Also, refrain from using the lights, it only wastes power even more! If you have to, only use it for a few seconds. Repeat until you reach 6 AM!
