Keep your camera on foxy at all times quickly checking constantly, when she runs check the camera to get her to hit the door, when you are close to 6am and you see her gone just close the door and wait to stall. Bonnie and Chica are easy to deal with just spam the light until you see them leave. Freddy will laugh every time she laughs she moves, count her laughs until she gets to 5 when she gets to 5 immediately close the right door until you hear her laugh again then she will go back and forth from 4 to 5 so you need to listen for when to open and close the door. Foxy and freddy are the biggest concerns so just hope for good RNG.
