As expected, Hogwarts Legacy hides a lot of secrets and puzzles that we will have to try to solve in our adventure through Hogwarts, and one of those secrets are the arithmancy doors puzzles , doors that hide chests with rewards and that can only be opened if we solve a mathematical riddle.
What do the animal drawings mean?
As you've probably guessed, the animal symbols above the door must mean something. In fact, near the door you'll find stone triangles marked with the symbols "?" and "?" which you can interact with to reveal several of the icons above the door. But what should we do?
The secret is that each animal represents a number, and although the solution is hidden in one of the castle's rooms, it's actually quite easy. You just have to count from 0 to 9, starting with the first creature on the left and ending with the last one on the right . It looks like this:
How do you open the door?
With the creatures already numbered, now all you have to do is solve the mathematical puzzle that appears on the door. They are two triangles that represent a sum of three figures. Each vertex of the triangle represents a number (number represented with a number or with an animal) and the sum of the three vertices gives rise to the number that is inside the triangle.
The challenge is to figure out the values of "?" and "??" to select the correct creature for each vertex. Simple addition and subtraction will help you discover which creature to place in the stone triangles.
Where to find the meaning of the symbols
Although the solution to the symbols riddle is quite simple, the game hides the solution in one of the rooms of the castle. You will only have to go to the Arithmancy Classroom, which is located next to the Hogwarts Library Annex. There you will find a paper where the values that represent each creature drawn on the door are specified.
How many arithmancy gates are there?
The castle has a total of 12 Arithmancy doors , so you'll have your work cut out for you finding them all. Anyway, we've listed their locations below:
- center hall
- great gallery
- enchantment classroom
- ravenclaw tower
- middle aisle
- grand staircase
- hourglasses
- faculty tower
- north hall
- Big dining room
