The guide above is truly great for the actual "guide" to the night.
I wanted to throw some tips into my own guide to perhaps help people with the "4-6AM" segment.
The most important thing is I highly recommend a stopwatch on your phone or whatever you can use. Every night is 6 minutes in real time, bringing the hours to a minute each.
The reason this is super helpful is for two reasons:
1) Knowing how close to 4AM you are for when it switches over.
2) Knowing whether or not you can allow Foxy in if you need to, assuming you're close to 4AM.
As for the actual tips when it comes to 4AM onwards, I STRONGLY recommend taking a clip of the last 30 seconds before your death, this helped me very much. My friend and I were both doing it at the same time, and to be able to have a peer review your death or even just looking over it yourself, you can sometimes see why you died when you did.
I found out I was just being too slow because of my controller not wanting to either run to the door or immediately close it. I have a solution.
When running to a door keep tapping
so your character closes the door immediately, and then hold it. The SECOND you hear footsteps away from the door run back to the bed by spamming
. Just repeat this and I managed to complete it.
With this guide, I have completed the original four games starting in early December 2020. I completed FNAF 1 in around a week by 12/11/2020. I ran through the majority of FNAF 2 and 3 in December also but got stuck on 10/20 and Aggressive Nightmare for over a year and a half, until I completed FNAF 2 on 4/9/2022, then FNAF 3 on 4/23/2022. With this completed on 4/30/2022, I have finished this game also in under a week. I did write a guide for beating Ennard on Sister Location, and a guide on FNAF 2 10/20.
Anyway, good luck everyone, and have a good day!
