Abyss School Guide | Floor 1 Puzzle Solution

In Abyss School, you have to go through 10 floors. Unlocking each will help you progress in the game. This guide will show you how to solve the Floor 1 puzzle.

Collecting the First Key Pieces

• Locate the first key piece by opening the locker.
• The second item is placed on this shelf.
• Open the third drawer to find the third component.
• After acquiring all three pieces, combine them to produce a complete key. Use this key to unlock the door and proceed to the next chamber.

Observe the Chalkboard

• This room's chalkboard says B: 8. Make a note of this for future reference.
• First, turn off the classroom lights, then the hallway lights. This sequence exposes an important detail in the classroom window.
• You can find a crowbar near the classroom windows. It allows you to enter a crawl space and find a key piece inside a red container.
• Inside the crawl space, there is a yellow bin with a closet key. Use this key to open the closet in the classroom and retrieve the final key component.
• Assemble these parts to create the key and unlock the next door.

Deciphering clues and retrieving key pieces

• The whiteboard in this room reads C: 4. Note this because it's necessary for a subsequent puzzle. Turn on the air conditioner in the classroom.  
• A critical component will drop to the floor underneath it. The men's bathroom key is located in the brown drawer on the right side of the classroom.
• Pick up the sponge in the men's restroom.
• Enter the women's restroom to retrieve detergent.
• Return to the men's restroom and use the sponge and detergent to remove a stain. This will reveal the safe passcode: 3479. Enter the code 3479 into the school safe to obtain a pair of bolt cutters.

Unlock the Exit Door

You will come upon a door that requires a passcode, denoted by the characters C A B. These letters correspond to the chalkboard clues in earlier rooms.

• C: 4
• A: 2
• B: 8
