In the game titled “Blue Prince,” there are over 100 distinct rooms for exploration. To fully understand the storyline and complete the game, you’ll need to examine every detail within each room and solve an assortment of puzzles. Among these rooms, one that can be selected is known as the “Treasure Trove.
As a passionate enthusiast, I’m thrilled to share my insights about the enigmatic Treasure Trove in Blue Prince. If you’re yearning to delve deeper into the lore of the Blue Prince and unlock the game’s true ending, this guide is your key. It’s designed to help you unravel every secret hidden within the Treasure Trove room, offering a comprehensive walkthrough. So, let’s embark on this exciting adventure together!
How to Get the Treasure Trove in Blue Prince
In the game ‘Blue Prince’, The Treasure Trove isn’t something you begin with. Instead, you’ll need to search for it throughout the game to unlock its location. If you’ve ventured into the Underground region, you might have stumbled upon a locked red door. This door is situated in the long corridor leading to the Sanctum. Just before the gate, there’s a secret passageway on the left. Follow this hidden path, and you’ll discover the door there.
To open the red door hidden beneath the underpass in Blue Prince, you must first create a Boiler Room within your own house. This room serves as an energy source, enabling electricity to flow through ventilation systems in the ceiling and illuminate other rooms. However, it’s not just for home lighting – it also conceals the key to unlocking the red door.

On one side of the ground level in the Boiler Room, there’s a stationary red box that appears to be inactive when power is sent to it. However, if you direct power to this red box first, then venture into the underpass, you’ll gain access to the red door. Inside, you’ll find a secured cage, which serves as a safe in the game Blue Prince. The correct date for the combination lock on this safe is May 8th. After unlocking the gate, enter the room, grab the Treasure Trove, open the red envelope, and collect the gem.
Treasure Trove Secrets in the Trunks in Blue Prince
Whenever you enter the Mystic Chamber within your residence, you’ll observe an assortment of trunks positioned between the two entrances. These trunks could be colored white, blue, pink, or black and adorned with a symbol of the sun, fire, or moon at their peak. Each one is secured and requires a key to open. So, what lies within these chests? To put it simply, scrolls of parchment.
Based on the specific color patterns you encounter, each one holds different meanings that can hint at whether certain colors or combinations are accurate or misleading. Given the numerous instances, manually searching for all of them might be tedious. Here’s a comprehensive list if you prefer not to figure it out yourself:

The True Treasure of the Trove in Blue Prince
The hint points to the “Blue Prince” Shrine’s Monk’s Blessing as the key to finding the real treasure in the Trove, which isn’t within the house itself. You can activate this blessing by offering the Shrine specific coin amounts: 13, 29, 45, 61, or 77 coins. Each additional number you use increases the duration of the blessing; for instance, 13 gold grants you three days while 29 offers four days.

In the room where you spent your day’s end, exteriorly, the power enables you to set up the Treasure Trove. Upon its placement, a unique type of chest will appear within the Trove, but it won’t open with any keys or house items. Instead, you’ll need the Key of Aries to unlock it.
How to Find the Key of Aries in Blue Prince
The Key from Aries is one of the toughest and intricate enigmas found in the game Blue Prince. To crack it, you must meticulously follow these steps to secure this distinctive key. Begin by resolving the Chess riddle, then move on to the Castle conundrum, followed by the Mora Jai mysteries hidden within the enigmatic chamber, decipher the riddles, and finally, unravel the CASTLE code.
The Chess Puzzle Solution
To locate the mysterious key, here are your options:
1. You must first solve the Blue Flame puzzle within the game ‘Blue Prince’, which grants you access to the elevator leading underground.
– Many of the house’s rooms contain chess pieces as decorations.
– These large ornaments serve as puzzle piece counterparts and you require one of each kind to complete it.
Here are the rooms containing each type of chess piece:
1. The room with the King (Roi) piece.
2. The room with the Queen (Dame) piece.
3. The room with the Rook (Tour) piece.
4. The room with the Bishop (Fou) piece.
5. The room with the Knight (Cavalier) piece.
6. The room with the Pawn (Pion) pieces (there are usually multiple of these).

Once you’ve added one unique room from the list provided to your home, come back to the Underground and position each piece on the 5×9 game board at the spot that matches the location of that specific room within your house. For instance:
After putting a distinct room from the given list in your residence, revisit the Underground, and arrange each piece on the 5×9 game board at the position that corresponds to where that particular room is located within your home.

How to Solve the Castling Puzzle
After successfully figuring out the Chess challenge, you’ll be presented with multiple power choices, each associated with a piece from the puzzle. In your personal drafting space at home, these powers will grant you unique benefits.

Piece | Power Name | Power Description |
---|---|---|
Pawn | Ambition of the Pawn | When you reach rank 8 each day, you may choose Knight, Bishop, Rook, or Queen powers. You gain the power of that piece until the end of the day. |
Knight | Mantle of the Knight | Adds the Armory room to your draft pool. |
Queen | Gambit of the Queen | Each time you draft a room in the Queenside of the house, you lose five steps and gain a key. |
King | Banner of the King | Each day, you may choose a room color via your inventory/menu. Rooms of the chosen color are more likely to be drawn while drafting. |
Bishop | Piety of the Bishop | You do not have to pay tithes. Instead, you gain +30 gold the first time you enter the Chapel each day. |
Rook | Resilience of the Rook | You may draw floor plans up to four times when drafting the four corner rooms of the house. |
Noticeably, there’s a breakable wall on the right side in the Chess puzzle room. By using the Blue Prince’s crafted item, the Powerhammer, to shatter it, you’ll discover a hidden code behind the wall. This message is quite straightforward: it reads “CASTLE”. In relation to chess and this puzzle, it seems to suggest a clue for the next step.

If you decide on the Rook’s power, followed by another attempt at solving the Chess puzzle using the King’s power (or the reverse), you’ll be performing what’s known as Castling. In chess, this move permits a simultaneous movement of the King and the Rook. This will create an opening within the Chess board’s confines.

Each Mora Jai container holds pieces of a poem written on individual sheets. Unravel this puzzle to guarantee you possess the necessary details for the following stage.
The Mora Jai Riddle in the Unknown Room in Blue Prince
If you put all the pages together in order, it reads:
Will a youth approach with empty arms,
without gifts nor gold nor mannered charms,
on the Sacred Hour, that timeworn phrase
in Aries Court where the King now lays.
A sullen cross as five stars align,
and in the sky above, a brilliant sign,
a patient figure a reckoning great,
the black key is lying with the last king of eight.

- You need to enter with no items in your inventory, no gold, no Blue Prince gems, no Ivory Dice, nothing.
- Draft an Observatory inside the house, and make sure that the Southern Cross is one of your Constellations for the day.

By putting all the letters together, you create a six-word sentence where each word has three letters. Hints for their meaning are found in the classroom settings.
- CIX: The first word in this puzzle is a Roman numeral. It translates to 109.
- ADD SIX: Add six to 109, and you get 115.
- TOR: Ejaran word for “rotate something counterclockwise.”
- LOR: Ejaran word for “word.”
- ETT: Ejaran word for “East.”
With this, you now have all the steps you need to complete the Clock puzzle.

- The clock starts at 1:30.

- Wind the clock to 1:15. Press the button again.
- Rewind the clock counterclockwise until the minute hand is pointed at the word East, which is right next to the V on the clock. The time will read 12:26. Press the button.
Inside the tomb, the Key of Aries will be found. From now on, whenever you enter this room, the tomb will automatically unlock. However, to get the key again, you must solve the Cipher puzzle anew each time with the same answers. Once you have the key, take it to the locked box in the outdoor Treasure Trove and use it to open the box and discover its secrets.
