"Five Night at Freddy's: Sister Location" is just like the rest of the other games before it. It has tons of easter eggs as well as secrets waiting to be deciphered by crafty fans. Here's one particular mystery that not everyone has cracked yet.

In a video posted by Corzix, one mystery is awaiting to be deciphered. The uploader of the video figured out of a way to simplify the process if learning what the voice was about on Night Three.

All it required was speeding up the recorded footage in order for the deep voice to speed up as well and be more apprehensible and it was a series of numbers. As the uploader and the comments in the video speculates, it is a repeating pattern, which makes it possibly shorter in length.

A 10-minute gameplay clip was speed up by 100 times, which resulted less than 3 minutes.

Most of the community have listened and the number pattern that follows is like the one below:

4814877484881478774477784848111788118177744771741844148418781877447487748787844487778778487447814841184817118114471871411171111414871841144

Many observed that only the number 1, 4, 7 and 8 are being used so it is also possible that these numbers are the key to something else in the game.

However, up to this point, nobody has ever deciphered what the numbers are for. There's no way to tell whether they need to be entered on a panel of some sort or even an indication of a date.

This isn't the only code in the game and players and fans can bet that more still lies somewhere. In fact, one code is 1983, and this could be used to access a hidden location that will bring players to a nostalgic place reminiscent of the first "Five Nights at Freddy's" game. This is also required to get the secret ending.
