Blue Prince Wine Cellar Coat of Arms Puzzle Solution Guide

Solve the Wine Cellar Coat of Arms puzzle in Blue Prince using Roman numerals, Blue Memos, cipher logic, and item clues.

Some puzzles don’t show their true purpose at first glance. If you’ve walked past the Coat of Arms in the Wine Cellar a few times and dismissed it as just another design detail, you’re not alone. But there’s more to it than appearance. To progress further, you’ll need to understand how clues, numbers, and specific keys come together across multiple rooms.

In this article, we will discuss everything you need to know to solve the Wine Cellar Coat of Arms Puzzle in Blue Prince.

How To Solve the Wine Cellar Coat of Arms Puzzle in Blue Prince

Start by Recognising the Coat of Arms

You’ll see the Coat of Arms etched into several rooms, such as the Wine Cellar and the Master’s Bedroom. The design carries a Roman numeral: MCCXIII, which converts to 1213. That number isn’t just decorative—it’s your first lead. Two numerical values will eventually come from it. But more on that in a moment.

Get the Blue Memos First

Before anything else, you need to collect Blue Memos, which only appear under certain conditions. You must:

• Unlock eight trophies.
• Buy the Blue Tents perk from the Gift Shop.
• Then draft any blue-coloured room in row or rank 8 of the manor.

Once the perk is active, blue rooms can generate a Blue Memo. You’ll find relevant ones in:

• The Wine Cellar
• The Mechanarium
• The Vault
• The Throne Room (called Throne of the Blue Prince after reclaiming the crown)

These notes contain bits of background and riddle hints. For the Coat of Arms puzzle, they’re essential.

Understand the Numeric Core Rules

This puzzle runs on a specific type of number logic. To get the rules, find the File Cabinet Key in the dark tunnel on the Grounds. That key unlocks a drawer in the foreman’s nook located underground between the mine cart area and the rotating gear section.

Inside that drawer is a document explaining how Numeric Core operations work. Here’s how they break down:

• Apply math operations (add, subtract, multiply, divide) to each digit.
• The first number remains as it is.
• Reorder the remaining digits and apply different operations.
• Ignore PEMDAS rules entirely.
• The result must always be a whole number—no negatives, no decimals, no fractions.

So when solving, keep trying different sequences until you land on a valid answer.

Decode the Roman Numeral Clue

You already have MCCXIII, which is 1213 in Arabic numerals.

Now look at the digits in two ways:

1. 1213 → Add the digits: 1 + 2 + 1 + 3 = 7
2. Break down the Roman numerals:
   • M = 1000
   • CC = 200
   • XI = 11
   • II = 2

Use this sequence: 1000 ÷ 200 × 11 − 2 = 53

From here, apply the Blue Memo hint from the Vault: “The Family Core is the sum of its digits.” So 5 + 3 = 8

That leaves you with two crucial numbers:

• 53 for a Deposit Box in the Vault
• 8 refers to Key 8, which you’ll get from the Gallery

Retrieve Key 8 and Unlock Box 53

Drafting the Gallery and the Vault can be difficult because they don’t always appear. If you can’t get both, prioritise the Gallery. Once you get Key 8, store it in the Coat Check. Then, wait for a future run where you can draft the Vault. Retrieve the key and unlock Deposit Box 53.

Solve the Cipher Inside the Vault

Opening Box 53 gives you a list of five rows of words, each with five words. You need to process every word using the Numeric Core rules, which involve converting letters into numbers (A=1, B=2, …, Z=26) and applying arithmetic.

The Words You’ll See:

• First Row: PIGS, SAND, MAIL, DATE, HEAD
• Second Row: CLAM, PEAK, HEAT, JOYA, WELL
• Third Row: TOAD, CARD, WILL, TAPE, LEGS
• Fourth Row: TREE, ROAD, MAID, SLAB, ROCK
• Fifth Row: HAND, VASE, SAFE, CLAY, TOES

Each word gives you one letter once solved. Let’s break down a few:

First Row

• PIGS: 16, 9, 7, 19 → 16 − 7 × 19 ÷ 9 = 18 → S
• SAND: 19, 1, 14, 4 → 19 − 14 × 4 ÷ 1 = 20 → T
• MAIL: 13, 1, 9, 12 → 13 − 12 × 9 ÷ 1 = 9 → I
• DATE: 4, 1, 20, 5 → 4 − 1 × 20 ÷ 5 = 12 → L
• HEAD: 8, 5, 1, 4 → 8 − 5 × 4 ÷ 1 = 12 → L

Second Row

• CLAM: 3, 12, 1, 13 → 3 x 12 – 13 ÷ 1 = 23 → W
• PEAK: 16, 5, 1, 11 → 16 – 5 ÷ 11 x 1 = 1 → A
• HEAT: 8, 5, 1, 20 → 8 x 5 – 20 ÷ 1 = 20 → T
• JOYA: 10, 15, 25, 1 → 10 x 15 ÷ 25 – 1 = 5 → E
• WELL: 23, 5, 12, 12 → 23 x 12 ÷12 – 5 → R

Third Row

• TOAD: 20, 15, 1, 4 → 20 – 15 x 4 / 1 = 20 → T
• CARD: 3, 1, 18, 4 → 3 – 1 x 18 ÷ 4 = 9 → I
• WILL: 23, 9, 12, 12 → 23 x 12 / 12 – 9 = 14 → N
• TAPE: 20, 1, 16, 5 → 20 – 16 x 5 ÷ 1 = 20 → T
• LEGS: 12, 5, 7, 19 → 12 – 5 / 7 x 19 = 19 → S

Fourth Row

• TREE: 20, 18, 5, 5 → 20 – 18 x 5 ÷ 5 = 2 → B
• ROAD: 18, 15, 1, 4 → 18 – 15 ÷ 1 x 4 = 12 → L
• MAID: 13, 1, 9, 4 → 13 – 9 ÷ 4 x 1 = 1 → A
• SLAB: 19, 12, 1, 2 → 19 – 12 x 2 ÷ 1 → N
• ROCK: 18, 15, 3, 11 → 18 – 3 x 11 ÷ 15 = 11 → K

Fifth Row

• HAND: 8, 1, 14, 4 → 8 – 1 x 4 ÷ 14 = 2 → B
• VASE: 22, 1, 19, 5 → 22 – 19 x 5 ÷ 1 = 15 → O
• SAFE: 19, 1, 6, 5 → 19 -1 ÷ 6 x 5 = 15 → O
• CLAY: 3, 12, 1, 25 → 3 x 12 – 25 ÷ 1 = 11 → K
• TOES: 20, 15, 5, 19 → 20 – 15 ÷ 5 x 19 = 19 → S

Do this for all 25 words, and you’ll end up with the sentence:

STILL WATER TINTS BLANK BOOKS

That’s your final result.

What To Do After You Get the Final Phrase

The phrase is more than a poetic clue. It’s functional. The only item in-game that holds water is the Watering Can, but don’t forget to gather Still Water too. That’s what the puzzle ultimately connects to.

Recap and Final Tips To Solve the Wine Cellar Coat of Arms Puzzle in Blue Prince

Here’s a summary of the required steps:

• Activate the Blue Tents perk.
• Locate Blue Memos in key rooms (Wine Cellar, Vault, etc.).
• Use the Roman numeral clue (MCCXIII) to get 53 and 8.
• Get Key 8 from the Gallery and use it on Vault Deposit Box 53.
• Solve the cipher using Numeric Core rules.
• Decode the sentence: STILL WATER TINTS BLANK BOOKS
• Collect items linked to this phrase.

If you’re missing a room during drafting, use the Coat Check system. That way, you don’t lose progress and can continue building toward this puzzle in a later run.
