Hogwarts Legacy has countless open-world activities, including numerous puzzles with unique rewards to keep you busy. One such activity is solving the symbol door puzzles.

During your ventures around Hogwarts Castle, you will have encountered a strange locked door with symbols around it and two dials nearby. At first, it might be a bit confusing to understand. But it is much simpler than you think.
There are a total of twelve such locked symbol doors around Hogwarts Castle. This guide will show you how to solve the puzzle and where to find all twelve locked doors.
Puzzle Solution & Door 1
While you can brute force your way into the locked doors by rotating the dials with the '?' symbol, there is a way to solve the puzzle and access these locked rooms.
First, you need a "cheat sheet" or a note containing different animal symbols corresponding to a specific number from 0 to 9. These are the same animal symbols you see on and around the locked symbol doors.
To get this note, first, fast travel to the Divination Classroom floo flame in the Library Annex.
From here, go through the small archway that leads to the wooden platform.
Follow the wooden platform until you see the first right.
Take the first right, and you will find your first locked door directly ahead.
You will also find a small chest on a bench before the locked symbol door.
Open it, and you will find the note with the animal symbols and the numbers they represent. We've given some names to the symbols to remember them better.
- 0 - Furry Beast.
- 1 - Unicorn.
- 2 - Graphorn.
- 3 - 3-Headed Dragon.
- 4 - Owl.
- 5 - Furry Spider.
- 6 - Lizard.
- 7 - Squid.
- 8 - Spider.
- 9 - Hydra.
Now, we will unlock the first door and use it as an example to explain how to solve the puzzle. The puzzle is simple mathematics, where you add numbers to get the target number.
When you approach the locked symbol door, you will get a prompt to 'Reveal' the content of the door. Upon doing so, it will show two numbers, each within a triangular shape.
Each corner of the triangular shape will have a number, one of the symbols on the note, and either a '?' or '??.'
There are two numbers, one at the top and the other at the bottom. Both are enclosed within their triangular shape. The top always has one question mark '?' and the bottom has two question marks '??.'
All you have to do is change them to a number that will add to the rest of the numbers, to get the final middle value.
Let's take the first door as an example. For the first door, we have 9 and 4. The 9 is surrounded by a triangular shape having 2, 3-headed dragon, and a '?.'
Now, we already have one numerical value, which is 2. To know the value of the 3-headed dragon symbol, we refer to the note we got from the chest.
We need 4 more to get the target value which is 9. This is where the dials come into play. First, go to the dial with '?', which is the value surrounding the target number 9.
You will notice that the dials only have animal symbols. The same symbols as the one on the note. Since we need the number 4, refer to the note to see which symbol represents 4. In this case, it is the owl symbol. So, change the dial to the owl symbol.
Similarly, look at the bottom number, 4, in this case. And it is surrounded by 0, 1, and '??.' This means the dial with '??' must be changed to a number that will add up with 0 and 1 to give us our target numerical value, 4.
For the bottom one to total up to 4, the '??' must be 3. So, once again, we refer to the note and see that the 3-headed dragon represents 3. We change the dial with '??' to the 3-headed dragon symbol.
After changing both dials, you can go to the door and see a prompt to open the door.
Now that you know how to solve the symbol puzzle door. Let's look at where you can find the rest of the doors and their solutions.
Door 2 & 3
The next two doors are relatively easier to find. Once you've opened Door 1, go through it and find two more doors inside the Arithmancy Class.
To open Door 2 (15 & 18), set the dials as follows:
? = Owl.
?? = Furry Spider.
To open Door 3 (17 & 8), set the dials as follows:
? = Lizard.
?? = Unicorn.
Door 4
Fast travel to the Potions Classroom floo flame in the Library Annex and turn around.
You will see the symbol puzzle door before you, just past the stairs.
The open Door 4 (21 & 17), set the dials as follows:
? = Spider.
?? = 3-Headed Dragon.
You might not see the second dial with '??' near the door. It will be on the floor above.
Door 5
Once again, fast travel to the Potions Classroom floo flame and, this time, go through the double doors ahead of you.
After going through the doors, turn left and go down the spiral staircase.
Once you're at the bottom, keep going forward until you come across a locked door to your left. It will have a level 1 lock on it. Use the Alohomora spell to unlock it.
Go through the door and keep going forward until you come out in an open area.
The locked symbol puzzle door will be located on your left in this open area.
To open Door 5 (22 & 9), set the dials as follows:
? = Graphorn.
?? = Unicorn.
Door 6
Fast travel to the Charms Classroom floo flame in the Astronomy Wing area.
You will find the door as soon as you turn left around the corner.

Door 7
Fast travel to the Grand Staircase floo flame in the Grand Staircase area.
Go out in the main staircase and go upstairs.
Keep going up until you see a blue corridor interior which is the Raven Claw tower.
Go through the corridor, and you will find a locked symbol puzzle door to your right at the end of the corridor.
To open Door 7 (13 & 21), set the dials as follows:
? = Owl.
?? = Furry Spider.
You can also reach this door by fast traveling to the Ravenclaw Tower floo flame in the Grand Staircase area, if you've chosen Ravenclaw as your house.
Door 8
Fast travel to the Grand Staircase Tower floo flame in the Grand Staircase area.
Go to the main stairs, and go downstairs.
Keep going down until you see the locked symbol puzzle door to your left on the wall. You will find the first dial on the wall to your left as you go downstairs. The second dial is on the wall directly in front of the symbol puzzle door.
To open Door 8 (23 & 19), set the dials as follows:
? = Lizard.
?? = Squid.
Door 9
Fast travel to the Grand Staircase floo flame in the Grand Staircase area.
Go up the stairs directly ahead of you.
As soon as you reach up the stairs, turn right, and keep going up.
Go forward, and you will find the locked door on your left.
The first dial will be by the door, and the second will be on the floor below next to the floo flame you just came from.
To open Door 9 (6 & 11), set the dials as follows:
? = Furry Beast.
?? = Furry Spider.
Door 10
Fast travel to the Faculty Tower floo flame in the South Wing area. This area is only available once you've completed the Caretaker's Lunar Lament quest. You don't need to fully complete the quest as you will unlock the area with the locked symbol puzzle door during the quest.
Once you've fast-traveled to the Faculty Tower, go forward, and as soon as you enter the open area, look to your right to find a door.
Go through the door and upstairs.
You will find the locked symbol puzzle door on the floor above.
To open Door 10 (13 & 14), set the dials as follows:
? = Furry Beast.
?? = Hydra.
Door 11
