To open Hogwarts Legacy puzzle doors all it takes is some basic maths, or arithmancy in wizard speak. It's not that hard once you understand what's going on but the game does little to help you, and hides the only clue to what's going on in an apparently random corner.
If you want to work it all out for yourself, the key to these answers can be found on a cipher hidden in a specific place in Hogwarts we can show you. This easily-missed paper scrap explains how these doors and their symbols work, but the game never leads you to it - so check the 'Puzzle door code' link to the left for that.
The unlocking charm Alohomora isn't going to help you here the way it does with the Hogwarts Legacy level 1 locks. To open these puzzle doors all you actually need to do is be able to count to nine. Those creature drawings and odd dice mechanisms look complicated, but each symbol simply correlates a number, and opening them is just a case of counting the symbols from left to right and then doing the sum those numbers give you.

How to solve the Hogwarts Legacy door puzzles
To solve the door puzzles in Hogwart Legacy you simply need to number the creatures around the door from 0-9, left to right. That will allow you to answer the two sums on the door by putting the missing value on the mechanisms you can interact with.
We've a more detailed explanation below but for now let's take a look at the whole process from start to finish.
How to find the code for Hogwarts Legacy puzzle doors
There is actually a piece of paper that will explain how to solve the puzzle doors in Hogwarts Legacy, but the game will never tell you. You might find it by accident, but it's basically just down to luck.
If you want to find the Hogwarts Legacy door puzzle cipher page, then follow these instructions:
1. Fast travel to the Divination Classroom Floo Flame, which is within the Library Annex.
2. Turn around and head back through the door behind you and along the wooden walkway
3. When you reach a junction, take the right turning and go along until you see a small landing with a chalkboard next to a puzzle door
4. Look to the right of the chalkboard and you'll see a blue box. Search it and you'll find the cipher page
The code itself explains that each of the magical beasts around the outside of the puzzle doors in Hogwarts Legacy has a numerical value. It seems to correlate to the number of legs or other appendages that creature has - although number 6 and 7 are a bit confusing. Essentially all you need to do is count around the edge of the door to give each symbol a value, starting from zero.
How to open Hogwarts Legacy puzzle doors
You don't need to find the explanation to open the puzzle doors in Hogwarts Legacy. You can simply count the creatures around the edge, starting with zero, to find out what number each symbolizes. This is key to solving the numerical puzzles that open the doors themselves.
First, interact with the door to "reveal" the puzzle which will show you two triangle patterns that spell out an equation. You need the three outside "numbers" to add up to the inner number and it just so happens that some numbers are represented by beasts instead.
So, let's take this door as an example:
For the top triangle, it works out as:
2 + Hydra (3) + ? = 9
So you'd need the ? to equal 4, which is the owl-like symbol. Turn the ? block to that.
For the bottom triangle, it works out as:
0 + 1 + ?? = 4
So that means the ?? must need to be 3, or the Hydra symbol. Turn the ?? to that.
With those in place the door will swing open. It's simply just about getting all the numbers around each triangle to add up to the one in the centre. Easy when you know what the beasts actually mean. Behind the Arithmancy puzzle doors in Hogwarts Legacy is a room with gear and chests for you to loot.
