Locate Springtrap. Finding Springtrap, who is typically in cam 10, should be done first thing in the evening. Keep your lens trained on him. He might blur the image on the screen, which would let him move. Search the cameras to find him if he does this. If there is a mistake, only shut the camera.
Utilize the audio. Use the audio button, which is on the bottom left of the camera layout, directly over the vent camera toggle, to entice Springtrap to a nearby camera. Remember that you can't use it in vents; instead, double click on one of the vents you see him in to close backrooms game.
Save your left glance for emergencies only. Except in cases of errors or when Springtrap is seen running by the window, there is no reason to look to the left. If it is getting close to midnight, you can keep staring at him if he is near your room (not in a camera, but outside your office), hoping there isn't a ventilation problem, till it is six in the morning. It's ideal to do this when the night is already nearly over.
Watch the vents closely at all times. Click "Toggle Map" and check all of the vent cameras if you hear noises in a vent that resemble those in FNAF 2. If he is in a vent, double click to seal it, obliging him to choose a different route. Since it doesn't actually assist, there is really no purpose in blocking a vent he isn't in.
Phantom Freddy should not be taken into consideration. Just unlock your camera or maintenance panel if you spot him going outside your office window. You must stare at him for a long enough period of time and wait for him to reach the end of the hallway before he can jump scare you. After that, you can remove your maintenance panel or camera.
