As you explore the enigmatic Mt. Holly mansion in Blue Prince, you may have encountered the intriguing fusebox within the Utility Closet. This seemingly simple panel of six glowing buttons holds the key to a significant reward, but its solution is far from obvious. Unless you've diligently explored both the Mailroom and the Office, you might find yourself randomly pressing buttons in frustration. However, if you've gathered the necessary clues from these rooms, solving the Utility Closet puzzle is simply a matter of knowing the correct sequence of button presses. This guide will provide you with a detailed, step-by-step walkthrough to illuminate the path to the Gemstone Cavern.

Blue Prince: solve the Utility Closet puzzle

The beauty of Blue Prince lies in its interconnected puzzles. You do not need to reset the day to have the Mailroom and Office accessible simultaneously. The key is to ensure that you have visited both rooms at some point during your current or previous runs and carefully noted the clues found within them.
  • The Mailroom Clue: In the Mailroom, locate the desk on the right side. There will be a sheet of paper on this desk that contains a crucial piece of information for solving the Utility Closet puzzle. Make sure to examine it thoroughly.
  • The Office Clue: Similarly, once you are in the Office, you will need to access your emails via the computer terminal. The content of these emails will provide another vital piece of the puzzle's solution.
Once you have gathered the clues from both the Mailroom sheet and the Office emails, return to the Utility Closet and interact with the fusebox. Here's the precise sequence of button presses to solve the puzzle:





  • Initial State: Begin by tapping each of the six buttons once. This action will turn every light on, and they should all be green. This serves as your starting point for the puzzle.
  • First Sequence:
    • Next, hit button five once – this should change its color to blue.
    • Then, press button six once – it will turn red.
  • Second Sequence:
    • Now, go back and press button five again – this should cause it to blend into purple, and button six should visually follow along, also appearing purple.
  • Third Sequence:
    • Hit button five two more times (for a total of four presses since the initial turn-on).
    • Then, tap button four once. You should now see button five remaining purple.
  • Fourth Sequence:
    • Keep going by pressing button four twice more (for a total of three presses).
    • Next, press button three once to make it purple.
  • Fifth Sequence (Working Back Down): Now, work back down the line, following the established pattern of pressing each button until it turns purple:
    • Press button two until it turns purple.
  • Sixth Sequence (Button One):
    • Finally, press button one three times – this should bring its color in line with the others, turning it purple.
  • The Twist:
    • Now, introduce a change by tapping button four once. This single press will cause button four to flip to white.
  • Seventh Sequence:
    • Next, press button three thrice (three times). This will turn button three green again. While you are doing this, button two should also turn blue.
  • Eighth Sequence (Turning Off Button One):
    • At this point, press button one repeatedly until its light turns off completely. Yes, off.
  • Ninth Sequence:
    • Now, hit button six repeatedly until it turns red again.
  • Tenth Sequence (Almost There):
    • With button five now blue, press it once more, which should cause button six to turn purple.
  • Final Sequence:
    • Finally, wrap it up by tapping button five twice (two more times). This should shift button five to red.

  • What Does the Utility Closet Puzzle Unlock?

    Once you have successfully entered the correct sequence and every light on the fusebox is in its designated final state, the box will respond, indicating that the puzzle has been solved. Interacting with the now-unlocked fusebox will grant you access to the Gemstone Cavern. This is a permanent reward that provides you with 2 free gems every morning (in-game day) going forward, making it a highly valuable unlock for your continued exploration of Blue Prince.By carefully following these step-by-step instructions, informed by the clues found in the Mailroom and Office, you can successfully solve the intricate Utility Closet puzzle and reap the daily rewards of the Gemstone Cavern. Good luck illuminating your path to this valuable unlock!
