Your objective in Blue Prince is to uncover the hidden 46th room within a sprawling manor consisting of 45 rooms. To access this elusive space, you must first navigate through the Antechamber. Wondering how to enter the Antechamber? You’ve come to the right place!
Accessing the Antechamber in Blue Prince

There are three access points to the Antechamber in Blue Prince: the western, southern, and eastern doors. All of these entrances are locked, requiring you to find specific levers to open them.
To locate those levers, you’ll need to draft certain rooms. However, drafting these rooms might be a challenge in itself.
The great news is that you only need to unlock one of the Antechamber doors to enter. Below, I’ll outline each method for accessing the doors so you can choose your preferred route.
Eastern Door of the Antechamber: Accessing the Great Hall
To enter through the eastern Antechamber door, you’ll need to draft the Great Hall to find the required levers. The challenge lies in the fact that although the Great Hall has four connections, three of the doors are locked, with only one leading to the lever for the eastern door.
To navigate this, ensure you have three keys ready before entering the Great Hall, or use a Lockpick to bypass the locks. Alternatively, drafting the Foyer before entering the Great Hall is a strategic move that unlocks all doors in Hallway-style rooms, allowing you to explore the Great Hall freely.
Southern Door of the Antechamber: Entering the Greenhouse
If you prefer accessing the Antechamber through the south door, you’ll need to locate the lever in the Greenhouse, tending to spawn on the eastern side of the manor.
The downside is that the lever in the Greenhouse is often broken, necessitating a previously acquired Broken Lever from another part of the manor. Compounding the issue, the Broken Lever doesn’t have a fixed spawn point, so you may need to search various rooms—your best chances are usually the Spare Room or Security.
If you have the Broken Lever, interact with the device in the Greenhouse to unlock the southern Antechamber door.
Western Door of the Antechamber: Unlocking the Secret Garden

To open the western door, you need to pull the lever located in the Secret Garden. Once inside, interact with the valves to direct the wind vanes towards the moon statue. This action will reveal a hidden compartment in the wall that contains the lever to unlock the western Antechamber door.
Do remember, you’ll first need to obtain the Key to the Secret Garden from the Billiard Room.
How to Access Room 46 in Blue Prince
Even after conquering the Antechamber in Blue Prince, your quest isn’t finished. To enter Room 46, you’ll delve into the Underground area armed with the Basement Key.
With the Basement Key, you can now open doors in the Underground, tackle the gear puzzle, and subsequently unlock the northern Antechamber door granting access to Room 46.
That wraps up the steps to enter the Antechamber in Blue Prince. For more tips and insights about the game, including solutions for the chessboard puzzle and a comprehensive list of safe code combinations, make sure to explore Moyens I/O!
