If you have seen those doors with an arch filled with beast portraits, these are your first puzzles in Hogwarts Legacy.
You’ll see these Arithmancy doors scattered inside the castle walls in Hogwarts.
Each door will reveal a picture of a puzzle you have to solve related to the beasts seen on the arch of the door.
We’ll show you a cheat sheet on solving these puzzles to unlock each Arithmancy door inside Hogwarts.
These doors contain rewards, such as gear and collectibles, to help you early in your journey as a wizard.
Magical Beasts Arithmancy
The beasts you see on top of the arch of each door are divination purposes in the world of Hogwarts.
They are ‘Arithmancy,’ which means ‘the practice of assigning numerical values to words for the purpose of divination.’
All these beasts have a corresponding number assigned to them.
When you reveal an Arithmancy door, you’ll see a ‘?’ and a ‘??’ with numbers and beast icons beside them.
The big numbers in the middle are the total of the three smaller numbers or beasts next to it.
You’ll choose the correct beasts with the corresponding ‘?’ and ‘??’ to open the door.
There are revolving stones marked with ‘?’ and ‘??’ near the arched door. You can rotate these stones to input the corresponding beasts to solve the puzzle.
Finding the revolving stone is also a puzzle because only some stones are near the arched door.
You can find them far away from the door or even on a different surface level.
We will help you solve all of these puzzles by location.
Cheat Sheet
The cheat sheet is available in the game. If you encounter these arched doors without finding this note, you are not alone.
I even tried solving the puzzle on my own without the cheat sheet. However, the Arithmancy Study Guide is obtained near the Divination Classroom Floo Flame.
Go up near the tower, and you’ll find a chest near a blackboard and an arched door. The cheat sheet is inside the chest.
The Astronomy Wing
Charms Classroom
This puzzle is simple. Both stones are found next to the arched door.

Middle Floor
In the Grand Staircase, you’ll find the first Arithmancy door on the middle floor (near the ground floor since the staircase is high).

Helpful Tips
Use your Revelio to scan the area. The spell detects all the stones and Arithmancy doors nearby. If you keep using Revelio, you can also find books and other interactables.
Another helpful tip is using dodge rolls to move faster. Since you are moving around Hogwarts castle to find these doors, you might as well do it more quickly.
Of course, sprinting is also a faster movement mechanic, but you are constantly turning to find these Arithmancy doors. You can mix it up!
If you are having trouble with textures or stuttering, you can adjust some of your settings to increase your FPS.
I’ve experienced ghosting through these Arithmancy doors when I opened them. It is a bit clunky, especially if you are playing on the PC.
