In this section I will go over your equipment and how each thing works.

The maintenance panel is used to reboot any failing system
Systems
There are 3 different systems that may need to be rebooted during the night they are, ventilation, cameras, and audio.
Ventilation is the least issue in my opinion reason being if it goes out all that happens is it causes a fake Springtrap to appear. It can go out if you get jumpscared by a phantom animatronic.
These are the second most important thing they may go out from using the monitor too much.
This is the single most important system in the game. It can be used to lure Springtrap into a room next to him.

Springtrap is the only animatronic that can kill you in this game and the only one you need to focus on. In each camera there are two places he may be (with the exception of camera 1 and maybe camera 3 there is 1 place he can be in these cameras). To deal with him you'll want to keep him in one spot to keep an eye on him easier. You can lure him with audio but remember audio only works if its played in a room he can enter that's right next to him. If he enters a vent find him then double click the vent to stop him from getting through.

This animatronic is a phantom version of Balloon Boy. He will disable your ventilation making you reset it. To get rid of him change camera or close your monitor when he appears.

This version of Freddy will appear walking down the hallway in front of you. He will disable your ventilation. To avoid him have the camera or maintenance panel open when he reaches the end of the hall.

This animatronic will appear on a few cameras. They will disable your audio. To avoid them close the monitor or change cameras before they get you.

Phantom Chica will appear in an arcade machine on cam 7. She will disable your ventilation. To avoid her you need to shut the camera really fast if she appears.

He will appear on the left hand side of the office. He will disable ventilation. To avoid him slowly turn to check if he's there if he is quickly open your monitor again then he will leave.

Phantom Puppet appears on cam 8 and then if looked at will come into your office and stop you from using the maintenance panel and cameras until they leave. There is no way to avoid them.

FNAF 3 has 2 endings a good ending and a bad ending. The bad ending requires you to play the game normally but the good ending requires you to play minigames in a specific order each night. So in this guide I'll put the section for the good ending at the end of each night.

Nothing happens on this night so use it to get used to the office and learn the layout.

On this night you need to play Balloon Boy's air adventure. To access this minigame you need to go to cam 8 and double click the Balloon Boy poster. Once in the mini game you need to jump on the platforms to reach the upper-left corner and jump through the wall there. Let yourself fall to the bottom then go to the right until you see another boxed up room then jump at the lower-left corner to get in the collect the balloon inside. Then you just need to complete the night.

On this night Springtrap is here and some of the phantoms are too. So since Springtrap is here I will go through the strategy that I used the entire game.
What got me through this game was doing this. Start by locating Springtrap then let him wander until 1 a.m. (he can't enter vents until then). At 1 try to get him to cam 7 then shut the vent connected to the room. After that you just need to keep flipping the monitor open and closed until you see the whole monitor screen go static for a little bit and hear him walking. When this happens play audio and he should go back to the room. In case this happens on this night I'll put this down, if you can't find him you can tell if he's in cams 1-5 by how loud the ambiance is this ambiance also plays when Freddy is in the hall, if he makes it to cam 2 shut the vent connected to it and then keep flipping the monitor and if he appears in the hallway quickly play audio in cam 2 and you might be able to live. If he makes it to cam 1 keep flipping the monitor and if he leaves the camera play audio, but if you see him in the doorway and it's 5 a.m. just stare at him and hope you live but if it isn't 5 you most likely will die.

On this night for the good ending you need to go to cam 7 and on the arcade machine hit the buttons on the left side in the order, Top-Left, Bottom-Left, Top-Right, Bottom-Right. Once you do this the second game, Mangles Quest, should start. Once the game starts you need to pick up all of Mangles parts and dodge the children and once you make it to the last screen jump up to the platform above the exit door and jump through the wall there and fall all the way down. When you're done falling go left one screen then you should see red balloons all over the screen jump from one balloon to another until you reach the top. Once at the top continue going balloon to balloon and then pick up the cake at the end. After that go back to BB's minigame and go out of bounds again. After jumping through the wall fall until you land on a balloon after landing go balloon to balloon until you reach a child on a platform. Walk up to the child to give them cake then you can finish the night.

On this night the only difference is that Springtrap is more active. So just use the strategy I told you before and you should get through all right.

On this night you'll want to look for cupcakes on cameras 3, 4, and 6. This will activate Chica's Party minigame. In this minigame you will want to go right one screen then drop down the hole. when you're down the hole you'll want to go to the top-left corner and jump out of bounds at the wall. Then go left one screen and give cake to the child. After the minigame complete the night.

In night 4 the difficulty just goes up and nothing changes so the strategy from before will work just remember to keep Springtrap in one place and you should be fine.

To access the minigame on this night you need to go to the wall tiles between the box of FNAF 2 stuff and the trash can type 3, 9, 5, 2, 4, 8. The tiles go in a grid with 1-3 on the top, 4-6 in the middle and 7-9 on the bottom. After putting the code in the Stage 01 minigame should start. To get through this minigame you need to jump into the kids then go back towards the stage to get pushed out of bounds then fall to the floor. After reaching the floor go right for 2 screens. Then jump at the edge of the next box to get on top of it. Next jump left onto the box on the next screen. Then keep jumping until you clip through into the box in the screen above. Once inside the box go to the right wall and jump to get on top. Then go to the left side of the box and jump again to get in the box above the one you're on. When inside that box go to the left and jump into the wall to get on top. Then just walk right and fall into the box on the next screen and give cake to the child. Once the minigame is over you can finish the night.

On night 5 again it's just a difficulty change so as usual the strat from before will work you just need to be faster.

For this night you just need to click the shadow Bonnie figure on the right side of your desk then you will be put into the minigame. When inside the minigame just keep moving left and pressing S until you clip through the wall and give cake to the child. Alternatively you can swap to the BB stage and go through the upper-left wall corner. When the minigame ends you need to go to camera 3 and click the puppet's poster. This will bring you to the Happiest Day minigame and if you played all the minigames and gave cake to the children you'll just need to walk right until you give cake to the children at the table. Once the minigame ends complete the night for the good ending and 2 stars in the main menu, the first star being awarded for beating the game the second for the good ending.

Night 6 is just a difficulty change like every other night so theres not much to say about it you just need to be fast and keep Springtrap in one spot. Once you beat the night you will earn a third star.

After night 6 you'll have unlocked everything in the extras menu. The stuff in the extra menu is pretty much just jumpscares and animatronic art or quick access to the good ending minigames. But the last section is cheats.

This is the hardest challenge in the game and is accessed by activating the aggressive cheat and playing on nightmare night. It's a huge difficulty change from night 6 but isn't too difficult if you get a little lucky and are fast. Completion of this night gives you the fourth and final star of the game.
