How to unlock the Throne Room floorplan in Blue Prince
To unlock the Throne Room floorplan in Blue Prince, you must first gain access to Blackbridge Grotto by powering up the Laboratory through the Boiler Room and solving the puzzles inside. Once the Laboratory is active, locate and collect three Microchips: one after the periodic table puzzle, another in a vase in the Entrance Hall, and the third buried near the bridge on the West Gate path. Place all three Microchips into the pedestal within Blackbridge Grotto to unlock a door, behind which you’ll find the Throne Room floorplan. Once obtained, the floorplan is added permanently to your drafting pool, allowing you to draft the Throne Room for 5 gems and access its unique late-game challenges.
Unlocking the Throne Room floorplan involves a couple other puzzles. First, you’ll have to open Blackbridge Grotto by powering up the Laboratory via the Boiler Room and solving the two puzzles inside.
Then, you’ll have to find all three Microchips to open the door in the grotto.
On the other side of that door in Blackbridge Grotto, you’ll find the blueprint.
How to draft the Throne Room in Blue Prince
To draft the Throne Room in Blue Prince, you first need to obtain its floorplan by solving several late-game puzzles. After unlocking Blackbridge Grotto-by powering up the Laboratory through the Boiler Room and completing its puzzles-you must locate and collect three Microchips to open a special door within the grotto. Behind this door, you’ll find the Throne Room blueprint, which is then permanently added to your draft pool. Drafting the Throne Room costs 5 gems and there are no restrictions on its placement orientation within your estate. Once drafted, the Throne Room becomes a pivotal space for progressing late-game objectives and unlocking new secrets in Blue Prince.
Picking up the Throne Room floorplan permanently adds it to your draft pool. There don’t seem to be any restrictions on where it is placed either east-west or on its rank. Drafting it costs 5 gems.
The inside of the throne room is disappointingly simple. The first time you enter, you’ll find a Sanctum Key to the right. That’s next to a king chess piece.
Beyond that, the only other thing to interact with is a lever behind the throne. That will open the northern door inside the Antechamber (which will save you having to trek down to the Underground the next time you want to visit Room 46).
What to do in the Throne Room in Blue Prince
Once you unlock the Throne Room in Blue Prince, it becomes the centerpiece for one of the game’s most intricate late-game puzzles. Inside, your main objective is to reclaim the throne by gathering and bringing three specific items-the Royal Scepter (set to blue), the Cursed Effigy, and the Crown of the Blueprints-into the Throne Room during a single run. Collecting these items requires solving various puzzles throughout the estate, such as completing the Castle Cipher for the Scepter, performing a ritual at the Shrine for the Cursed Effigy, and retrieving the Crown from Room 46. Once all items are assembled and you enter the Throne Room, a special cutscene will play, advancing the story and unlocking new lore, as well as the ability to unseal the Blue Doors elsewhere in the game.
The Throne Room’s description simply says, “Reclaim the crown.” Doing so, however, is anything but simple.
If you’ve read Lady Epsen’s Diary, you’ll know that it’s possible to draft the Antechamber in the Outer Room. Doing so requires you to have the Blessing of the Monk from the Shrineand you’ll have to call it a day in the Antechamber.
When you draft the Antechamber over along the West Path and then open the north door, you’ll find a new note that (finally) gives you your clue: “Steady is the scepter, deadly is the stone, heavy is the crown, ready is the throne.”
Where to find the scepter in Blue Prince
To find the scepter in Blue Prince, you must first solve the Castle Cipher Puzzle in the crypt, which rewards you with the Key of Aries. Next, you need to draft the Treasure Trove as an outer room using the Blessing of the Monk from the Shrine. Once the Treasure Trove is drafted outside, bring the Key of Aries to unlock the sealed chest within the Treasure Trove, where you will discover the Royal Scepter-one of the most powerful items in the game. The scepter allows you to select a color, making rooms of that color appear more frequently as drafting options. To keep the scepter, end your day in a room matching its color; otherwise, you can retrieve it again from the Treasure Trove if lost.
The scepter is the hardest of the three items to collect. It’s the culmination of an estate-spanning puzzle that will likely (definitely) take you multiple in-game days.
You’ll have to take a Power Hammer (Sledgehammer Battery Pack Broken Lever in the Workshop) to the room with the chess puzzle in the Precipice. That will reveal a pair of clues.
That will send you looking for fragments of a code spread across multiple rooms that will ultimately lead you back to the chess puzzle room. There, you’ll have to perform a castle (the chess move) by solving the chess puzzle twice – selecting either the king or the rook the first time, and the other the second.
Then, you’ll have to solve a series of Mora Jai puzzles in the next room for another series of clues that tell you to be back in this room with no items, money, gems, or keys at a specific time.
AND THEN, you’ll have to put the code you constructed into practice and solve a clock puzzle by entering three different times. That will get you the Key of Aries that unlocks a special chest that only appears if you draft the Treasure Trove in the Outer Room (via the Blessing of the Monk).
That is where you’ll find the scepter. Whew.
Where to find the stone in Blue Prince
To find the stone required for unlocking the Throne Room secret in Blue Prince, you need to locate the Cursed Effigy, which is referred to as the “deadly stone” in the game’s clues. The process begins by drafting the Book Shop, a rare room that can only be drafted from the Library. Once you have access to the Book Shop, you can obtain the Cursed Effigy within the manor. This item is essential for both unlocking the Throne Room’s secret ceremony and for enabling Curse Mode in the game. Make sure to gather the Cursed Effigy along with the Scepter (set to blue) and the Crown of the Blueprints before entering the Throne Room, as all three are required to trigger the event.
The stone referred to in the clue is related to the “The Curse of Black Bridge” book that you can buy in the Bookshop.
Once you buy it and request if from the Library, it quietly adds an item to the Mount Holly Gift Shop (that only unlocks after you’ve been to Room 46 for the first time). The next time you draft the gift shop, you can buy the Cursed Coffers for the appropriate amount of 13 coins.
This adds the coffers – a gothed-out chest – to the Shrine.
Head to the Shrine with a Sledgehammer (a key won’t work). You’ll get two warnings about what a bad idea it is (just like the story), but smash it open and pick up the Cursed Effigy (you fool).
This unlocks Curse Mode (and curses you). For two days, you’ll:
- Lose one resource every time you draft a red room
- Lose one step every time you draft a bedroom (purple room)
- Lose one key every time you draft a hallway (orange room)
- Lose one gem every time you draft a green room
- Lose one coin every time you draft a shop (yellow room)
Where to find the crown in Blue Prince
To find the crown needed for the Throne Room in Blue Prince, you must revisit Room 46 after your first clear of the game. The specific crown required is the Crown of Blueprints, which will appear on a desk in the northern Antechamber once you have drafted the Throne Room and unlocked access to this area. Unlike the Red Crown or Paper Crown found in the Closed Exhibit, the Crown of Blueprints is the only crown that fulfills the Throne Room’s requirements. Simply access Room 46 for a second time, enter the northern Antechamber, and you’ll find the crown ready to collect and use in your quest to reclaim the throne.
There are, technically, two crowns that you can find in Blue Prince. The one you’re after here is the Crown of Blueprints, not the red paper crown from the Closed Exhibit.
It’s actually the easiest (well, as easy as anything in this game is) to pick up. All you have to do is reach Room 46 for a second time. Luckily, if you draft the Throne Room (above), you’ve got a new lever to open the north Antechamber door. You’ll find the crown on the desk inside.
When you have it in your inventory, you’ll be able to remove red rooms from that day’s drafting pool. Doing so will earn you a gem.
How to reclaim the crown in Blue Prince
To reclaim the crown in Blue Prince, you must gather three essential items and bring them into the Throne Room during a single run. First, obtain the Royal Scepter by solving the Castle Cipher puzzle and ensure it is set to the blue color. Next, acquire the Cursed Effigy by becoming cursed at the Shrine-place coins in the bowl, remove them, then buy the Cursed Coffers from the Gift Shop and use a sledgehammer to open the box in the Shrine. Finally, retrieve the Crown of the Blueprints from Room 46, where it appears on the desk after your first visit. Once you have all three items-the blue scepter, the cursed effigy, and the crown-draft the Throne Room and enter with these objects in your inventory. Doing so will trigger a special cutscene and complete the process of reclaiming the crown, unlocking further secrets and progression in Blue Prince.
The crown can be grabbed on any day that you open the north Antechamber door. The scepter will stay in your inventory once you turn it blue and call it a day in a blue room – you’ll have to turn it blue for it to work in the Throne Room anyway. The effigy is the only real problem, so it’s safest to just stash it in the Coat Check until you’re ready.
Once you have all three items, take them all to the Throne Room. Doing that will turn the Throne Room blueprint into the Throne of the Blue Prince. With that new floorplan in hand, drafting eight blue rooms in a row will unlock all blue (the symbol, not the color) doors permanently.

Secret Lore Inside the Throne Room in Blue Prince
A Chamber of Hidden Histories and Puzzles
The Throne Room in Blue Prince is more than just a late-game achievement-it’s a nexus for some of the game’s deepest secrets and lore. Upon entering, players are immediately set on a path to “reclaim the crown,” but this task unfolds into a series of layered mysteries and narrative revelations.
Key Lore Elements and Secrets:
-
A Mysterious Ceremony and Poetic Riddle: Inside the Throne Room, players can trigger a secret ceremony that unlocks additional lore. A poem, known as the “Rhyme of the Throne Room,” can be discovered, especially if you follow hints from Her Ladyship’s Diary and use the Blessing of the Monk to save the Antechamber as an outer room. This poem and the ceremony it references are central to unraveling the room’s secrets.
-
Historical Significance: The Throne Room was once the seat of Orinda Aries, tying it directly to the game’s overarching narrative of shifting power and the legacy of the Aries family. Clues found here link to the broader story of Mt. Holly, including blackmail, political intrigue, and the mysterious disappearance of a children’s book author.
-
Unlocking Blue Doors and Permanent Upgrades: Placing the Throne Room in the manor and aligning eight blue rooms in a row grants the power to permanently unlock all special blue doors marked with a holly symbol, opening new areas and storylines for exploration.
-
Artifacts and Manuscripts: The room contains important items such as the Sanctum Key and manuscripts tied to the family’s history and the unpublished version of “The Red Prince,” revealing details that were censored due to their association with the Aries legacy.
-
Interconnected Mysteries: The lore unearthed here connects to other puzzles, such as the Blackbridge Grotto and the family’s will, which references sacred hours, sigils, and the deeper meanings behind the estate’s secrets.
In summary:
The Throne Room is a treasure trove of hidden lore, offering players cryptic poems, secret ceremonies, family artifacts, and narrative threads that tie together the fate of the Aries family and the mysteries of Mt. Holly. Solving its puzzles not only unlocks new gameplay possibilities but also reveals the true heart of Blue Prince’s story.
What is the significance of the mysterious ceremony in the Throne Room
The mysterious ceremony in the Throne Room of Blue Prince holds deep narrative and symbolic significance. Within the context of the game, performing this ceremony is not just a mechanical action-it is a pivotal moment that unlocks hidden lore, reveals the legacy of the Aries family, and ties together the estate’s most enigmatic secrets.
Symbolically, throne room ceremonies in broader lore and mythology often represent a transfer or affirmation of authority, the unveiling of hidden truths, and the restoration of rightful rule. In Blue Prince, this ceremony is closely linked to reclaiming the crown and understanding the true history of the estate, echoing themes of judgment, redemption, and the restoration of order seen in many throne room narratives. The ritual itself often involves deciphering poetic riddles or following clues left by previous rulers, which serves to immerse the player in the estate’s layered history and its unresolved mysteries.
Ultimately, the ceremony is significant because it acts as a narrative fulcrum: it both rewards the player’s perseverance in solving the game’s most challenging puzzles and provides a deeper understanding of the game’s central mysteries, connecting personal achievement with the unfolding of the estate’s hidden past.
