The Laboratory in Blue Prince is filled with intricate puzzles and mysterious machinery, making it one of the most challenging areas in the game. Among these puzzles, the
Laboratory Machine Puzzle stands out due to its cryptic nature, requiring players to decode clues hidden throughout the room. If you're struggling to figure out the correct sequence of levers to pull, this detailed guide will walk you through every step of the solution.
Step 1: Powering Up the Laboratory
Before you can even attempt the machine puzzle, you must ensure that the Laboratory has
power. Here’s how to do it:
Locate a Power Source – Rooms like the Boiler Room generate power.Connect the Laboratory to the Power Grid – Power travels through tiles that have ceiling conduits, such as:- The Gymnasium
- Security
- Passageway
- Other connecting rooms
You’ll know a room is properly connected if it’s surrounded by a blue glow (as seen in the image below).(Insert screenshot of a powered room with blue lighting if available.)Verify the Connection – Once power is successfully routed to the Laboratory, the machine inside will activate, allowing you to interact with it.Step 2: Understanding the Lever Puzzle
The core challenge involves
pulling levers in the correct order, which permanently unlocks a reward in Blue Prince. To solve this, you must
decode the hidden message scattered across the room’s posters.
The Clues: Two Periodic Tables
Inside the Laboratory, you’ll find
two key posters:
A Complete Periodic Table of Elements – This serves as your reference.An Incomplete Periodic Table with Numbers – This contains the puzzle’s code.Each number on the incomplete table corresponds to an
element’s position on the full periodic table. By matching these numbers to their respective elements, you’ll extract a set of letters that form a
hidden instruction.
Decoding the Numbers into Letters
Here’s how the cipher works:
- Each number represents an element’s atomic number (its position on the periodic table).
- The element’s chemical symbol (e.g., H for Hydrogen, He for Helium) provides the letters you need.
- The sequence of numbers on the incomplete poster translates into a phrase when read in order.
Example Decoding:
Let’s break down the first few numbers to see how this works:
NumberElement PositionElementSymbol
| 1 | 94 | Plutonium | Pu |
| 2 | 16 | Sulfur | S |
| 3 | 1 | Hydrogen | H |
Combining these, the first word becomes: P-U-S-H ("PUSH").Continuing this process for all numbers on the incomplete table, the full decoded message is:"PUSH THREE UP AFTER NINE"Or, when written as a continuous string (as it appears in-game):
"pushthreeupafternine"
Solving the Lever Puzzle
Now that you have the decoded instruction, here’s how to apply it:
Locate the Machine’s Levers – There are multiple levers, each numbered (though the numbering may not be immediately visible).Follow the Decoded Phrase:- "Push Three Up After Nine" means:
- First, pull Lever 9 (the "Nine").
- Then, pull Lever 3 (the "Three").
Activation – Inputting this sequence correctly will trigger the machine, granting you a permanent unlock in Blue Prince.Additional Tips & Troubleshooting
- Double-Check the Numbers – If the machine doesn’t activate, ensure you’ve correctly matched each number to its element.
- Power Stability – If the Laboratory loses power mid-puzzle, you’ll need to reconnect it before trying again.
- Alternative Interpretations – Some players report slight variations in the decoded phrase, but "Push Three Up After Nine" is the most consistent solution.
Conclusion
}The Laboratory Machine Puzzle in Blue Prince is a clever blend of observation, decoding, and logical sequencing. By carefully analyzing the room’s posters and translating the numbers into elemental symbols, you uncover the hidden instruction needed to manipulate the levers correctly.
With this guide, you should now have all the tools to power up the Laboratory, decode the cipher, and solve the lever puzzle with confidence. Happy experimenting!
