As I have beaten almost every custom preset (bar 20/20/20/20/20/20/20/20/20/20) I believe I am qualified to say I know my way around this game pretty well. Please note that this guide is based purely on my personal experience.


Some basics on defending against animatronics:
3 on the left (Bonnie, Toy Chica, BB)
3 on the right (Toy Bonnie, Chica, Mangle)
4 in the hall (Freddy, Toy Freddy, Foxy, Golden Freddy)
1 teleporting into the office (Golden Freddy)

Toy Chica, Toy Bonnie and BB can be defended against by putting the mask on when you see them in the blind spots and listening for the vent noises after the mask is on (except Toy Bonnie who walks across the screen). Don't just assume they went away because it could be another animatronic coming in on the other side, make sure you check the blind spot again after taking the mask off. Mangle also rarely shows up in the blind spot and can be defended against this way but more often then not is defended against the same way as the old models.

Bonnie, Chica, and Mangle can be defended against only when they come into the room, as soon as you see them you need to put the mask on. Mangle will often come in at the same time as other animatronics. They all come through the vents but skip the blind spots, (except Mangle sometimes appearing in the blind spot, see above). If you hear Mangles garbled noise while looking at a monitor, but hes not in the monitor then hes in the room with you.

Tip about Mangle: He is very hard to see when in the office as he hangs from the ceiling, just put the mask on and wait for the noise to stop.

Freddy and Toy Freddy can be warded off by putting the mask on when they peek into the room from the hallway and waiting or the sound of their footsteps, but it is more efficient and takes less time when you defend against them the same way as the old models, when they come in.

Golden Freddy can be defended from the same way as the old models but has a faster reaction time. He will teleport into the office and you need to put the mask on withing .8 seconds. He can also appear in the hallway as a floating head, if you see this turn your flashlight off immediately.

Foxy can only be defended against by shining your light on him every now and then.

Marionette (The Puppet) can only be kept at bay with the winidng of the music box.

BB disables your flashlight when he makes it in.

So nearly every custom night has the same strategy and that will be defined here:
1. Wind the music box.
2. Put down the screen and immediatly put on the mask.
3. Take off the mask after threat.
4. Flash down the hallway.
5. Check vent blind spots. (Press the switches)
6. Repeat.

In the beginning of every night you can just continuously wind the music box until you hear the "Danger" music.

If you have trouble on Night 6 this strategy works fine there too.

Foxy will appear on every night even if his setting is 0. (Else BB has no point)

Note that ANY animatronic on setting 20 WILL kill you 4~5 seconds after they are in position to, and you do not check them. Meaning that Foxy, for example, is in the hall for 4~5 seconds with no light he will kill you. This goes for the old models too, if you stare at your monitor for more then 5 seconds and they are in the room with you, you will die WITHOUT the chance to defend against them.

Using the power of math I have put together a perfect strategy for playing with level 20 AI. What you want to do is wind the music box for 6 ticks (3 seconds) then follow from step 2 in the strategy. If you lose count just follow from step 2 and start over again.

NEVER EVER WIND THE MUSIC BOX FROM EMPTY TO FULL.


Now for a preset to preset basis.

Keep your cursor near the bottom of the screen you can use this triangular movement for when you open and close the monitor. This will help minimize your reaction time too. Don't forget to be prepared for when the animatronics lower your screen for you.

This is easier then you may think, as you do not have to check the blind spots at all here. Just followthe basic strategy and make sure you keep your time at the monitor at 6 ticks (3 seconds) or less

Even though Foxy is set to 0 he will still appear, just remember to flash down the hall and you won't have to worry about him. Theres not much to say about this preset as it is rather easy, just wind the music box anywhere from 8 to 10 ticks unless you hear the vents.

You dont have to worry about the left vent blind spot at all here~

Golden Freddy appears rather frequently at setting 10, make sure you keep your reactions tight.

This preset can be harder then it seems. Even though there are only 3 animatronics, the difficulty will catch you off guard. When putting the monitor down with Mangle in the room MAKE SURE to flash foxy BEFORE you put the mask on to defend against Mangle, else the waiting time for Mangle to go away might be enough for foxy to attack. You DO NOT have to put the mask on at all here unless you hear mangle in the vents. Keep switching rapidly from the monitor to the hallway flash, Foxy will attack after 4~5 seconds of darkness.

Hard to imagine that Mangle is actually a female, and I guess this dispels old Chicas gender ambiguity. Don't forget that Mangle will sometimes appear in the right vent blind spot, check both here.

Have not beaten this one as of yet. Golden Freddy shows up really often so be fast with the mask, and don't wind the music box for extended periods of time. You do not have to worry about the right vent blind spot at all here.

As the name suggest's this isnt a very hard preset. You should be able to use the same strategy you used for Night 6 here.

Think of this as a pumped up Cupcake Challenge. On nights like this where every animatronic is active, sometimes luck can be a major factor. Sometimes the period of time it takes for an animatronic attack to end is enough to put Foxy or Mariachi over...

Use this mode to practice for the Golden Freddy preset.

(Coming Soon... maybe)

This is INCREDIBLY tight with the music box. I never have enough time to wind it.
I'll update this if I manage to beat this mode.
