In the enigmatic landscape of Blue Prince, discovering Room 46 is a prerequisite for claiming the mansion as your own. This elusive room stands at the core of the mystery that envelops the game. While players are often teased by its presence, finding it requires navigating a series of challenging tasks. Many adventurers find themselves meandering through countless hallways in hope of a lucky encounter with Room 46. If this sounds familiar, you’re not alone on this journey.
Here’s a detailed guide to successfully uncover Room 46.
Navigating to Blue Prince Room 46
Your primary goal is to unlock all four Antechamber gates: west, south, east, and north. Each gate is concealed behind intricate puzzles and locked doors that you must solve throughout the Mount Holly Estate.
Accessing the Western Antechamber Gate (Secret Garden)
Commence your quest in the tranquil surroundings of the Secret Garden, which features lush greenery complemented by mechanical wind vanes.
- At the garden’s heart, you’ll find a pedestal adorned with several wind vanes.
- Adjacent to this, various valves await your manipulation to adjust the direction of the vanes.
- Your objective is to align all wind vanes so they point west to unlock the gate.
- Adjust the valves with precision; some trial and error may be necessary.
Upon successful alignment, you will hear a distinct click or observe an animation that confirms the western Antechamber gate is unlocked.
Accessing the Southern Antechamber Gate (Greenhouse + Security Room)
Your next destination is the Greenhouse situated on the eastern part of the manor’s grounds.

This location encompasses your second major objective.
- Inside the Greenhouse, you will encounter a lever switch; however, the lever itself is missing.
- Your next task is to locate the broken lever essential for activating the switch.
- Search within the Security Room, which is linked to various surveillance and utility areas.
- Expect to find the broken lever resting on a desk or shelf.
Once you have the lever, return to the Greenhouse, insert it into the switch, and pull it to unlock the southern Antechamber gate.
Accessing the Eastern Antechamber Gate (Great Hall + Foyer Drafting)
Proceed to the Great Hall, an expansive and elegantly designed room at the center of the mansion featuring several locked doors.
- You’ll soon notice that most entry points to the Great Hall are secured.
- If you encounter a blockade, retrace your steps to the Foyer positioned just before the hall.
- Utilize the drafting mechanic available here, as it alters the configuration of corridors and rooms—this will unlock all adjacent doors.
- Once you have redrafted the space, return to the Great Hall and investigate further.
- Inside, you’ll discover another lever—pulling this will activate the eastern gate of the Antechamber.
Accessing the Northern Antechamber Gate (Basement Gear Puzzle)
The final gate may be the most challenging but features cleverly designed puzzles.
- Near the locked northern gate, you’ll uncover a cryptic hint: “To go up, you must go down.”
- This suggests that the solution lies within the Basement.
- Pick up the Basement Key found nearby and locate any access points leading underground.
- In the dimly lit Basement, utilize your key to open locked doors you encounter.
- Explore the area until you locate the Rotating Gear Puzzle, which requires you to align a series of interconnected gears in a specific order.
- Succeeding in this task will reveal the final lever for the northern Antechamber gate.
Once you pull the lever, return to the main Antechamber, where all four gates will now be open.
With all gates to the Antechamber unlocked, make your way through to finally access Room 46 in Blue Prince.
