Confused by those strange doors in the Hogwarts Legacy door puzzle?
The ones with magical creature symbols and weird math problems? I was also confused, but I solved them, and now I’m here to help you. These doors are called Symbol Door Puzzles, and they’re scattered all over Hogwarts Castle. You’ll need to solve them to unlock secret rooms filled with gear, collectibles, and valuable rewards.
This guide explains everything you need to know about the Hogwarts Legacy door puzzle, what it is, how to solve it, where to find it, and how to get all the answers without guessing.
Let’s make these puzzles easy once and for all.
What Is a Hogwarts Legacy Door Puzzle?
In Hogwarts Legacy, you’ll find locked doors decorated with magical creatures. These are called Arithmancy Doors or simply puzzle doors. They look like normal doors but have a golden arch filled with beast symbols and a triangle-shaped puzzle in the center. Each puzzle asks you to solve a simple equation using symbols.
You’ll often hear these called:
- door puzzle Hogwarts Legacy
- Hogwarts Legacy puzzle door
- hogwarts legacy door puzzle key (which is a myth—no key is needed)
Once you know the trick, every puzzle becomes easy.
How Do the Door Puzzles Work?
Each door has two triangle equations, and each one is missing a number. These equations look like this:
Top equation:
Number + Symbol + ? = Total
Bottom equation:
Number + Symbol + ?? = Total
You’ll see two spinning panels nearby—one for the “?” and one for the “??”. To unlock the door, find the missing number in each equation and spin the dials to match the correct symbol.
Creature Symbols and Their Numbers
| Number | Creature Symbol |
|---|---|
| 0 | Demiguise |
| 1 | Unicorn |
| 2 | Graphorn |
| 3 | Runespoor (3-headed snake) |
| 4 | Fwooper (owl-like bird) |
| 5 | Quintaped (5-legged creature) |
| 6 | Salamander (lizard) |
| 7 | Grindylow (squid-like) |
| 8 | Acromantula (giant spider) |
| 9 | Hydra (multi-headed serpent) |
How to Solve a Door Puzzle (Step-by-Step)
Let’s walk through the steps using a real example.
Puzzle Example: hogwarts legacy door puzzle 5 12
When you interact with a door, you might see:
Top Triangle:
5 + 0 + ? = 12
Bottom Triangle:
4 + 1 + ?? = 12
Step 1: Solve the Equation
- Top: 5 + 0 = 5. You need 12. So ? must be 7 → that’s the Grindylow.
- Bottom: 4 + 1 = 5. You need 12. So ?? must be 7 → again, the Grindylow.
Step 2: Spin the Dials
- Spin the “?” dial to the Grindylow symbol.
- Spin the “??” dial (usually on the opposite side of the hall or stairs) to the Grindylow.
Step 3: Open the Door
Once both symbols are correct, the door unlocks. Inside, you’ll find a rare gear item or collectible.
