How to solve the laboratory puzzle in Blue Prince

Join Blue Prince in an exciting adventure to solve the laboratory puzzle! Unravel mysteries and test your skills in this thrilling challenge.
For players venturing into the ever-shifting mysteries of Mt. Holly manor in Blue Prince, the laboratory presents a significant and multi-faceted puzzle. Released just recently on April 10, 2025, this unique puzzle adventure title from Raw Fury and Dogubomb challenges players to solve a new mystery daily within the manor's constantly changing floor plan. The laboratory puzzle itself is comprised of two distinct segments that require careful observation and deduction: a periodic table cipher and a lever machine activation. This guide will walk you through both parts of the laboratory puzzle to unlock its hidden rewards.

Solving the Laboratory Puzzle in Blue Prince:

Once you locate and enter the laboratory within the Mt. Holly manor, the puzzle will present itself in two key stages:

The Periodic Table Cipher: This segment requires you to identify specific items within the laboratory to decipher a hidden code based on the periodic table of elements.

The Lever Machine Activation: The second part involves using the clues you obtain from solving the periodic table cipher to correctly manipulate a lever machine and unlock a new area.

The Periodic Table in the Laboratory:

• You can find a periodic table chart displayed above the laboratory's main working bench. This bench is also equipped with a small microscope and a stand holding test tubes, making it a distinct feature of the room.
• At the opposite end of the laboratory, you will find a bulletin board. This bulletin board holds the code sheet that is essential for solving the laboratory puzzle. The code sheet will be located right next to the lever machine that you will interact with later.

Deciphering the Secret Code:

To uncover the hidden code, you will need to carefully examine the code sheet on the bulletin board. This sheet will contain a sequence of numbers. Your task is to correlate these numbers with the corresponding elements on a standard periodic table of elements. You will need to note down the abbreviations (chemical symbols) of these elements in the order of the numbers presented on the code sheet.

Example: The guide explicitly states that the first element you need to look at is Plutonium. On a standard periodic table, Plutonium's symbol is Pu, and it occupies the position marked with the number 1 on the Blue Prince code sheet (in this specific instance). You need torepeat this process for all the numbers listed on the code sheet, noting down the corresponding element abbreviations in order.

Following this process for all the numbers on the code sheet will yield the sequence of abbreviations: "Pu S H Th Re Eu Pa F Te Rn I Ne".

The next step is to rearrange the spaces within this sequence of abbreviations to form a coherent Englishsentence. By doing so, you will discover the solution to the periodictable cipher: "Push Three Up After Nine."

The Lever Machine in the Laboratory:

• Once you have successfully deciphered the code from the periodic table, turn your attention to the machine with a series of levers, clearly marked with numbers ranging from 1 to 10. This machine is located near the bulletin board where you found the code sheet.
• Now, you need to use the solution you obtained from the periodic table puzzle: "Push Three Up After Nine." This sentence directly instructs you on how to manipulate the levers on the machine.
• Following the instruction, you need to push lever number 9 up first, and then push lever number 3 up.
• Successfully manipulating these levers in the correct order will unlock a new region in the game called the Blackbridge Grotto. This new area is described as a cavern located close to the mansion and provides you with the ability to remotely access an extra terminalevery day, potentially offering new clues or interactions.

Additional Notes for the Laboratory Puzzle:

• Power Requirement: The lever machine in the laboratory requires power to operate. Before you can interact with it and input the solution, you must ensure that the laboratory is connected to a powered boiler room within the Mt. Holly manor. There are two primary ways to establish this power connection:
  • Ceiling Ducts: If the laboratory has visible ducts on the ceiling, and these ducts are linked to a functioning boiler room, the laboratory will receive power through this ventilation system.
  • Direct Connection: Alternatively, there might be a direct connection (likely indicated by pipes or cables) running between a powered boilerroom and the laboratory itself. Ensure this connection is established.
• Unlocking Blackbridge Grotto: Once you have successfully provided power to the laboratory andcorrectly manipulated the lever machine using the "Push Three Up AfterNine" solution, the Blackbridge Grotto will bepermanently unlocked as a new area within your game. This new regionoffers the benefit of remotely accessing an additional terminal eachday, potentially providing further insights into the mysteries of BluePrince.

By following these steps, youcan effectively solve the laboratory puzzle in Blue Prince, decipheringthe periodic table cipher and correctly activating the lever machine tounlock the intriguing Blackbridge Grotto and its daily terminal access.Remember to ensure the laboratory is powered before attempting to usethe lever machine. Good luck with your continued exploration of Mt.Holly manor!
