While I'll try to be vague about it, this guide isn't exactly spoiler free because
of the gratuitous screenshots I post up here.

There are multiple episodes with Hello Charlotte: Episode 3, and you only really need to concern
yourself with this guide after episode 0 is complete.
(Which you'll know when you get the achievement for it)

Technically, you only really need to do well on 4F and 9F for the achievements.
But I just added 6F for good measure, why not.

If there's anything I'm missing or need to clarify on - please feel free to tell me!

This is the floor where you're able to get the 'Brainiac or Just a Cheater?' achievement.
Though I believe only the 2nd puzzle is where you can get it.

You'll start off after waking up in Logos Village, finding that you're unable to leave without answering a riddle. However, you can't answer the riddle due to an additional layer added onto it and you'll need four hints to figure out thow to answer.


To collect all four hints, here's what you should do:

1.) You'll be given a fortune cookie by the villager who was kind enough to house you when you woke up if you ask about the Word Sea to them. The fortune inside the cookie is one of the hints you need, so go ahead and use it!



The hint should say: "O=9"

2.) There are a handful of houses that you're allowed to enter, one of them will have a book on the floor. If you want to just head straight there, the area should look like this:



The hint should say: "4 is an upside-down perpendicular."

3.) Go into the gallery and receive your museum tickets from the person giving them out - they're the hint you're looking for.



The hint should say: "The exhibition is R-rated! 3 visitors allowed at a time!"

4.) Finally, the gatekeeper will give you the last hint after collecting the other three.



The hint should say: "S=8"

Answer: 8934

Q2: Basically, a maze sort of puzzle where stepping on the wrong space means getting impaled by spikes.

To get the steam achievement, all you have to do is follow this guide without looking at it in your inventory.

So starting from the black line on the map, go four steps up, one step left, three steps up, etc...

And hopefully you've gotten the achievement!

Nothing here particularly lets you gain a steam achievement but... here's the answers if you still need them for any reason!

Basically, remember this sequence and you won't die. Easy-peasy, right?

Answer:



**Only step on the Blue and Yellow tiles!




**Do not fear warm colors!

Take 10 steps up, then switch to the left.


After that you're able to proceed upwards without dying!


Aaaand now you're done with the puzzles in 6F and can now proceed with the story, neat!

The floor you'll need to achieve "I Can Handle It, Mr. Honikker!", where basically, you can't ask Felix for help whatsoever.


So after descending into the shady-looking entrance, you find yourself stuck. This is basically the room you find yourself in:



The only room that's unlocked, and the only room that honestly matters is Room 433, which is the left room. Here's what you'll find when you enter and the places you need to interact with throughout the whole puzzle:




First thing's first, you need to inspect the laptop first so that they'll realize that they need to use a fusebox to get the electricity on. On your way out, take 5 coins from the piggy bank to use for the vending machine outside the room where you can get a Soda Can.

After that, use the fusebox to generate power for Room 433.

Go back in, if you inspect the laptop again, you'll find that it's password locked.
Not much you can do, so instead, place the Soda Can you got from the vending machine inside the fridge. Hijinks will happen and you'll find a small Key within in the can.

After that, use the key to inspect the locked desk drawers to get a USB stick. With it, you can access the computer.

After rebooting the computer with the USB stick plugged in, you'll find a map. If you inspect where the area is, you'll be told that you need something to break the floor with. For that, all you need to do is find the axe when you inspect the bed, because any normal person keeps an axe under their pillow. With the axe, strike where the 'X' is on the map.



Remember to bring your unconscious, bleeding dead weight while you're at.


You'll land yourself in an empty classroom. From the top-lefthand corner, you'll find a bookshelf containing three books about morse code, sign language, and the caesar cipher. Notes about the first two are down here:






There'll be a super hint if you check this desk.

It'll look something like this:


After that, you just need to translate it from the books in the shelves.

Answer: V19


You need to use ROT3 (hinted from the blackboard) from the red text found in the school diary by encrypting it using the caesar cipher in order to unlock the exit.

Answer: ILQG HALW

Remember not to leave anyone behind on your way out!


Before you panic - no, you're not actually timed for thirty minutes on this puzzle. I know, I spent like 40-50 minutes on this and nothing happened.

Here are the hint memos that you can find by inspecting the room:




You can use math skills to figure out the pattern needed to find what the red triangle is
and Felix's example about weekdays looking similar to the blue square's hint,
then add two of those numbers together for your answer...

blue triangle 10
+ red triangle 11

Oooor you can totally skip it all and straight up enter the code the moment you walk in.
That's fine too, I guess.



= the password to put in the keypad 21


After unlocking the hatch, you need to interact with this ominous looking door to get this recipe in order to start making the bomb:


Just make sure you inspect the fridge, the green florence flask and the red conical flask on the table, and the closet at the top right corner to collect all the ingredients you need.



When you're inspecting the green liquid on the table, you'll be asked on what ingredient you'll need to pick up. No stress if you don't know and pick the wrong answer - Bennett won't take it if it's not the right choice. But to save time, the answer is hydrochloric acid.

After all that all you need to do is interact with the items in your inventory to combine ingredients together. Again, no stress if you forget what the recipe is when you're asked where goes where, Bennett will point out if the choice is the incorrect answer before you accidentally muck up your bomb.

The end result of your efforts should have the following:

• Soda Can x1
  
• KCl with sugar x1
  
• Flask with H2SO4 x1
  
• Cork x1

After that, you need to interact with the ominous looking doors once again for Bennett to combine all the pieces together. Now all you need to do is hide in the hatch with your human meatbag and continue on with the story.



And you've done it! Honikkerpedia-Schmonikkerpedia - who needs it anyways!
