At first glance, the Throne Room in Blue Prince looks like just another milestone on the road to Room 46. In reality, it’s one of the most important rooms in the entire estate—a narrative, mechanical, and symbolic crossroads that separates a completed run from the true endgame.
Yes, the Throne Room can help you unlock the final door. But that’s only its surface-level function. Its real purpose is hidden behind cryptic clues, cursed artifacts, and one of the most punishing multi-run puzzles Blue Prince has to offer: “Reclaim the Crown.”
This 2025 Throne Room guide covers everything:
-
How to unlock the Throne Room blueprint
-
How to use the hidden lever to reach Room 46
-
A complete, step-by-step breakdown of the Reclaim the Crown puzzle
-
The safest strategy to handle the Cursed Effigy
-
What you unlock after claiming your throne
If you’re aiming to uncover Blue Prince’s deepest secrets, this room is unavoidable.
๐ How to Unlock the Throne Room
Your steps are correct. The Throne Room is a secret blueprint unlocked through a very specific progression chain:
Step 1: Solve the Laboratory Puzzle
Complete the periodic table puzzle in the Laboratory. This grants access to the Blackbridge Grotto, a critical mid-to-late-game location.
Step 2: Find the Three Microchips
You must collect all three microchips scattered throughout the estate:
-
Blackbridge Grotto – One chip is already installed.
-
Entrance Hall – Hidden inside a breakable vase.
-
West Gate Bridge – Found by digging in a specific spot along the bridge.
Step 3: Activate the Pedestal
Place all three microchips into the pedestal inside the Blackbridge Grotto. This permanently unlocks the Throne Room blueprint, which will now appear as a rare draft option.
๐ก Pro Tip
The Throne Room is notoriously rare when drafting. To improve your odds:
-
Use Ivory Dice rerolls
-
Unlock and leverage the Observatory’s Inkwell constellation (requires 50–99 stars)
These tools dramatically increase your chance of seeing the Throne Room during a run.
๐ The Throne Room’s Two True Purposes
Once built, the Throne Room serves two completely different functions—one short-term, one long-term.
1️⃣ The Hidden Lever (Reaching Room 46)
As your guide correctly notes, a concealed lever sits behind the throne itself.
-
Pulling this lever unlocks the north-facing door in the Antechamber
-
This grants access to Room 46
-
It serves as an alternative to the lever found in the Underground’s Inner Sanctum
This makes the Throne Room a valid—and often safer—path to the credits.
2️⃣ “Reclaim the Crown” (The True Endgame Puzzle)
The message “Reclaim the crown!” is not flavor text—it’s a directive.
This puzzle requires entering the Throne Room while holding three specific legendary items. Completing it permanently transforms the room and unlocks additional post-game content. This is considered one of Blue Prince’s most demanding challenges.
๐งฉ The “Reclaim the Crown” Puzzle — Complete Step-by-Step Guide
To solve this puzzle, you must bring three unique items into the Throne Room at the same time.
Clues pointing to these items appear across:
-
A special statue riddle in the Antechamber
-
A Classroom slide
-
The Red Prince manuscript
Required Items
| Item | Location | Key Details & Strategy |
|---|---|---|
| Crown of the Blueprints | Room 46 | Pick it up from the desk after reaching Room 46 for the first time. |
| Royal Scepter (Blue) | Treasure Trove | Solve the Castle Cipher Puzzle to obtain the Key of Aries. Use it on a chest in an outdoor Treasure Trove. You must choose the blue gem variant. |
| Cursed Effigy | Shrine | 1. Buy & read The Curse of Black Bridge from the Book Shop. 2. Purchase Cursed Coffers from the Gift Shop. 3. In an outdoor Shrine, use a Sledgehammer to break the stone chest and retrieve the effigy. |
๐จ Critical Strategy: Handling the Cursed Effigy
The Cursed Effigy is the most dangerous part of this puzzle.
While carried, it:
-
Severely reduces your steps
-
Actively drains resources
The Universal Strategy
Immediately store the Cursed Effigy in a Coat Check room after acquiring it.
Only retrieve it at the absolute final moment of your Reclaim the Crown run—right before entering the Throne Room. Attempting to traverse the estate with it for any length of time is almost guaranteed to end your run.
✅ Executing the Perfect Throne Room Run
This puzzle cannot be brute-forced. It requires multi-run preparation and precise execution.

This unlocks:
-
A new set of Blue Door puzzles
-
The next chapter of Blue Prince’s deepest post-game mysteries
-
Long-term progression paths tied to royal authority and legacy
Final Thoughts: A Beginning Disguised as a Throne
The Throne Room is not an endpoint. It’s a declaration.
By reclaiming the crown, you move beyond survival and inheritance—you become an active force shaping the estate’s deepest systems. Few puzzles in Blue Prince demand this level of foresight, planning, and restraint.
