Door with triangles and numbers on its face in Hogwarts Legacy. The door is also surrounded in gold images of magical beasts.

Encountering locked puzzle doors with golden images of magical beasts is something you’ll encounter as soon after you exit your common rooms in Hogwarts Legacy .

When you try to open the door, two triangles appear on the door face. Some have numbers, some corners have a picture of a beast, and the last corner has a question mark. Continue reading to find out what beasts should take over the last corner, and how to solve these Arithmancy door puzzles in Hogwarts Legacy — including the locked door you’ll find in the Central Hall.

The arithmancy door puzzle in Hogwarts Legacy can be solved by solving a math problem . Each of the magical beasts around the door is associated with a number, and you can guess the number based on the images themselves.

For example, the unicorn having one horn is one, and the spider has eight legs so it is eight. However, the trickiest part that seems to stump many players is that the numbers start from zero .

To unlock the puzzle door, you’ll have to find the two missing numbers in their triangles. Simply add the two numbers together and subtract the sum from the number in the center of the triangle. The resulting number will be associated with a magical beast that you’ll have to input into triangles around the door. If you’re unsure of what number the magical beasts represent, check the image below to see what magical beasts are associated with what number.

Central Hall door puzzle solution in Hogwarts Legacy

If you’re still having trouble unlocking the door puzzles, follow along an example of an arithmancy door puzzle that can be found in the Central Hall.

  • Reveal the triangles on the door by interacting with it.
  • Add the two numbers on the corners of the triangle together. In the case of the image above, it would be 11 + 2 = 13 for the top triangle and 5 + 9 = 14 for the bottom triangle.
  • Subtract the number inside the triangle by the sum of the two numbers from the step before. In this case, it would be 21 - 13 = 8 for the top triangle and 17 - 14 = 3 for the bottom triangle.
  • Find the magical beast associated with those numbers, which is the spider for the top triangle and the three-headed snake.
  • Search for nearby triangles on the wall that are labeled with “?” and “??”. If you’re having a hard time finding the triangles, use revelio near the Arithmancy door, and look around to see highlighted triangles on the wall.
  • Input the magical beasts from step four on their respective triangles. For the image above, the triangle with a “?” would be the spider and the triangle with a “??” would be the three-headed snake.
  • Interact with the door again to unlock it, and open the chests inside to collect your rewards.

Now you’ve mastered these doors, other obstacles we can help with are eye chests , picking locks with Alohomora , and finding all of the Demiguise statues .

On numerous occasions in recent years, billionaire and Harry Potter creator J.K. Rowling has taken public stances against inclusive transgender laws and trans rights , and has written fiction that has been condemned by LGBTQ+ organizations for its use of harmful anti-trans tropes. Hate crimes, as well as legislation that denies the rights of trans people, have become more prevalent in the U.K. since 2019 , and, more recently, in the United States as well .

According to an FAQ from Hogwarts Legacy publisher Warner Bros. Interactive — the parent company of Avalanche Software, the game’s developer — Rowling is “not directly involved” with the creation of Hogwarts Legacy . Regardless, the sales and widespread attention generated by a AAA video game will benefit Rowling, and that has led some fans to decide not to buy the game . For a more in-depth explainer of the yearslong controversy leading up to Hogwarts Legacy ’s release, read Polygon’s breakdown .

Harry Potter STEM: Arithmancy Math

harry potter maths problem solving

Have you heard of Arithmancy from Harry Potter? It was Hermione’s favorite subject, so I thought it would be fun to delve in a bit and learn about it with my kids. I created an Arithmancy Math code printable set. It is full of Harry potter references and loads of fun for kids to try to figure out!

Harry Potter Arithmancy Math

What is Arithmancy?

Did you know that arithmancy is not just a fictional thing made up by J.K. Rowling? The term arithmancy comes from two Greek words. Arithmos means number and manteia means divination. So, arithmancy is the study of divination through numbers.

Harry Potter Arithmancy codes

Arithmancy is a form of numerology that was developed by ancient Greeks during war times to try to determine and potentially change the outcome of a battle. Other forms of Arithmancy were also used by the Chaldeans, the Pythagoreans and the Kabbalah.

Arithmancy class was Hermione Granger’s favorite in the Harry Potter books  Order of the Phoenix  &  The Prisoner of Azkaban . Arithmancy is a branch of magic used for predicting the future in the wizarding world.

The letters of names or words are added together to create numbers that correlate to different meanings. They were used to predicts a person’s personality strengths or weaknesses.

arithmancy math codes

It reminds me a lot of horoscopes. While I do not really believe these things are true or real, I think it is a fun thing to play around with and make into a learning activity related to one of our favorite book series!

Harry Potter Math

The Harry Potter Arithmancy printable that I made includes 2 pages of decoding phrases using the decoder key chart. The letters are all assigned a number. These are tricky to decode because there are several options that each number can equal, so it may take some trial and error to get the words right. That makes to more fun!  But not to worry, there is an answer key in case you get stuck!

Arithmancy name

It also includes a page to discover your Arithmancy “personality or character number”. To do this you add up the letters of you name based on the code. Then you continue adding them until you are down to a single digit. This single digit matches up with a personality number. Fun, right?!

Harry Potter Maths

My class love the Harry Potter game I made up.

We sit in a circle, and I call two children into the middle. The children stand back to back, and when I say they start walking away from each other. I call out a maths problem (add, subtract, multiply, divide), and the first child to get the answer must turn round and ‘zap’ the other child with their wand before they can answer.

The pupils love this game and are always asking to play it!
