Blue Princehas one simple objective: reach Room 46 in a manor with only 45 rooms. Yet, due to the random nature of Mt Holly, reaching this mysterious room is a lot more difficult than it seems. This is especially the case with how it can be difficult to get the rooms you need to even reach it. Daunting as it may seem, it is possible, and there are several different ways of reaching it. In fact, it can be done without solving some of the morecomplex puzzlesin the game. So here is how you can reachRoom 46in Blue Prince.
Significant spoilers below, proceed with caution.
How to Reach Room 46 in Blue Prince
In order to enter Room 46, you must first reach the Antechamber on the other side of the manor. While you’re able to try to build rooms toward it, you will be at the mercy of whatever rooms you get. Even then, it isn’t recommended that you try to straight-shot toward the Antechamber as you could end up in a situation where youhave no gemsor keys and no way of progressing.
Even if you do everything right, there is still a chance RNG will not be in your favor, and you will run out of doors to open before you can even reach the Antechamber, let alone Room 46.
Antechamber Levers
Even if you manage to connect a room to the Antechamber, you’re able to’t enter it unless you find one of the levers that open the doors. There are three rooms with levers: the Great Hall, the Secret Garden, and the Greenhouse. The Greenhouse lever is broken, so you will have to hope you get lucky and find it in another room. As a result, your best bet is to attempt to go after the lever in either the Great Hall or the Secret Garden, though to get into the Secret Garden you will need the key which spawns randomly in other rooms.
Keep in mind that each lever opens a different door to the Antechamber. The Great Hall opens the east door, the Secret Garden opens the west door, and the Greenhouse opens the south door. So plan accordingly as you are drawing new rooms.
Inside the Antechamber
Once you’ve managed to open one or more doors into the Antechamber and successfully enter it, a pillar will appear with the Basement Key. Room 46 is on the other side of the door with the moon on it, but you’re able to’t open it yet. There are two spots where you can use the Basement Key. The first is at the bottom of the Foundation elevator (if you’ve found it and placed it in the manor) and the second is at the bottom of the well outside the manor. To reach the bottom of the well, you must drain the fountain completely in the Pump Room.
Both doors remain permanently unlocked once you use the Basement Key on them, but if you call it a day before you’ve used the key twice, you will have to go back to the Antechamber and get the Basement Key again to unlock the door that you missed. Both doors connect to a large underground area with several puzzles, including the Reservoir that you’re able to drain.
The Basement
The basement has several entrances, and you will want to have as many unlocked as possible, as it will make it easier to get around. Your goal is to find the Inner Sanctum, where you will find a lever that opens the north door in the Antechamber and reveals Room 46.
The main obstacle between you and the Inner Sanctum is the giant gear puzzle room. By rotating the platforms, you can reach other parts of this room, and the gear itself can be raised and lowered. To reach the Inner Sanctum, you will need to use terminals on different sides of the room and then raise it up so that you can connect the lower platform to gain access to the mechanical-looking tunnel known as the Underpass.
When done correctly, you will be able to enter the Underpass by going through the door at the bottom of the fountain, going down the tunnel, and pushing the minecart so that you can access the tunnel it was blocking. The entrance to the Underpass will be off to the left, as depicted in the image above.
Once you are in the Underpass, keep going and open the door directly ahead. This leads you to the Inner Sanctum, where you will see a large lever and eight doors. Pull the lever and ignore the doors for now. At this point, all you have to do is pick a route that can get you back to the Antechamber.
Pay attention to how many steps you have left. As long as you reach the Antechamber with at least one step left, you will be able to enter Room 46 andbeat the game.
What Happens After You Reach Room 46?

While searching for a way to reach Room 46, you likely noticed that there is something else going on in the story beyond just inheriting a mysterious manor. Perhaps you even foundthe blue flamesyou can activate. If you want to know more, you may continue exploring the manor for more secrets. The best place to start your search would be to go back to Room 46.
After you reach it the first time and watch the ending, you will be able to properly explore the room on your second visit. You will need to verify to pull the lever in the Inner Sanctum again, as the doors of the Antechamber always close when a new day begins.
