In the immersive world of Blue Prince, players will encounter a plethora of cryptic clues essential for solving a variety of puzzles. Among these, a particularly intriguing one can be found in the Wine Cellar, which may leave you scratching your head. This guide is here to demystify the coat of arms clue and provide insights on how to navigate this number puzzle.
The Wine Cellar itself is somewhat of a cul-de-sac within the game. Here, players can discover three Blue Prince gems, alongside potential dig spots that may appear after acquiring the Root Cellar. While the space is relatively unadorned, it houses vital hints that are crucial for advancing to later puzzles. Your primary focus should be on the coat of arms located prominently above the table where the gems are displayed.

Navigating to the Wine Cellar Number Puzzle in Blue Prince
Accessing the Wine Cellar number puzzle requires completing several prerequisites. Here’s a list of what you need to achieve before diving into this intriguing aspect of the game:

- Locate Room 46 within the game.
- Gather at least eight trophies to progress.
- Invest in the Blue Tents upgrade, costing 400 Blue Prince gold coins.
- Utilize the Burning Glass on the sundial in the Orchard, incorporating microchips into the sundial, and download the latest pack of experiments from the computer. Use these experiments to clear all boxes from the crate tunnel.
- Within the crate tunnel, you’ll find a stone altar on the right featuring a helmet, which contains a filing cabinet key.

This key grants access to the filing cabinet in the foreman’s office, strategically located near the mining cart inside the underground area adjacent to the large turning room. Inside the cabinet, you will find the essential clues to decipher the numerical mystery connected to the Wine Cellar.

To decode the Roman numeral MCCXIII, follow the guidelines specified in the blue notes. The breakdown results in M, CC, XI, II, translating numerically to 1,000, 200, 11, 2. By applying the formula of 1,000 ÷ 200 x 11 – 2, you arrive at the final value of 53. This number is linked to box 53 in the Vault as referenced in the blue notes. If you sum the digits (5 + 3), the result yields 8.

Consequently, you can unlock Vault 53 using the eight-shaped key obtained from the Gallery. This same key is instrumental in granting access to Room 8 in Blue Prince, reinforcing the intricate connections woven throughout the game.
By following these detailed steps, players can adeptly manage the complex puzzles within Blue Prince and uncover the secrets hidden in the Wine Cellar.
