Blue Prince’s many puzzle rooms are its most beloved feature, right next to the brilliant addition of the roguelike formula, the beautiful art style, and the gripping yet optional hidden story that permeates throughout the game.

One of the many rooms that you will encounter in your Blue Prince run is the Office, a puzzle room with, seemingly, not a lot going on. However, players will find a secret safe if they poke and prod around the room a little.

This article contains very minor spoilers about the gameplay and lore of Blue Prince.

The small garden in Blue Prince's Cloister room is tantalizingly close, but there's no obvious way to get there unless you know the hidden mechanism.

How to Locate the Office Safe in Blue Prince

There is a safe hidden behind one of the large busts in the office, as denoted by a stone hand pointing towards it from the shelves lining the walls. To access this safe, players need to make their way to the other side of the room to the office desk, which has a computer, some notebooks, a picture, a lamp, and some ink on top of it.

If you encounter a room that doesn't have anything going for it, you should look closely again for small clues.

Once behind the table, look at the right drawer, which will be slightly open. Interact with it to open it and twist the knob inside it. Doing so will make the bust rise up and reveal a hidden safe behind it. This safe requires a code, which you'll need to find before you can open it.

Making a wish might not get you better luck in Blue Prince, but it can aid you in the coming days.

How to Find Office Safe Code in Blue Prince

To find the code for this safe, players need to understand three hints, which are as follows:

  • Hint 1: The safe codes in Blue Prince are often related to dates.
  • Hint 2: On the desk, you will see a note asking Bridgette to check books for sale, with four given titles. Of these four, only March of the Count is black, while the rest are red.
  • Hint 3: The bust in front of the safe is that of Count Isaac. (This information can be found by visiting the Foyer)

If you combine all those hints together, the answer will reveal itself as 0303. This is because March is the third month, and there are three miniature busts of Count Isaac present in the room.

Inside the Office safe, you’ll find a large gem and a bright red letter from “X” with an infinity symbol on it. This letter, addressed to Mr. Sinclair, goes into detail about a blackmail incident that the owner of the mansion had been through, revealing additional lore.
