How to solve the North Hall door puzzle in the Astronomy Wing of Hogwarts Legacy is an article and includes walkthroughs, equations, images, and videos.

Introduction to the Puzzle


North Hall is a room located in the Astronomy Wing of Hogwarts Legacy. In order for players to progress further within the game, they must solve a door puzzle. The door is adorned with a number of creature icons from left to right, representing the numbers from 0 to 9. Two equations inscribed on the door must be solved to unlock the door.
  • Overview of the Mechanics

In order to solve the puzzle, players must first identify the creature icons. They must then solve the equations inscribed on the door itself. Once the equations have been solved, players must roll the triangles set into the walls near the door so that they display the creature icons for the missing numbers in the “?” and “??” spaces on the door. 

How to Solve the Puzzle



  •  Identify the Creature Icons

The creature icons on the door arch represent the numbers from 0 to 9. The icons include the spider (0), the rat (1), the boar (2), the salamander (3), the owl (4), the scorpion (5), the dragon (6), the lion (7), the griffin (8), and the hydra (9).

  • Solve the Equations

The two equations inscribed on the door are as follows: 2 + dragon (6) + ? = 10 and 3 + 1 + ?? = 7. To solve the equations, players must identify the creature icons for the missing numbers in the “?” and “??” spaces. In the first equation, the “?” must be 6 (represented by the salamander creature icon). In the second equation, the “??” must be 3 (represented by the hydra creature icon).

  • Rolling the Triangles

Once the equations have been solved, players must roll the triangles set into the walls near the door so that they display the creature icons for the missing numbers in the “?” and “??” spaces on the door. For example, the top triangle reads 2 + dragon (2) + ? = 10, so the “?” must be 6 (represented by the salamander creature icon); roll the “?” triangle to the left of the door until it shows the salamander creature icon. Similarly, the bottom triangle reads 3 + 1 + ?? = 7, so the “??” must be 3 (represented by the hydra creature icon); roll the “??” triangle to the right of the door until it shows the hydra creature icon.

Concluding the Puzzle

  •  Unlocking the Door

Once the creature icons for the missing numbers have been rolled into place, the door can be unlocked. Congratulations! You have solved the North Hall door puzzle.

  • Finding the Ruined High Stairway Conjuration

In the small chest inside the door, players can find the Ruined High Stairway Conjuration, a powerful spell that can be used to unlock doors and secret passages. Additionally, players can find some sweet gear in the large chest.

  •  Tips for Future Players

For future players who are stuck on the North Hall door puzzle, here are some helpful tips. Make sure to carefully observe the creature icons on the door arch and take note of the equations inscribed on the door. When rolling the triangles, pay attention to the creature icons for the missing numbers in the “?” and “??” spaces and make sure to roll the correct triangle to the left or right of the door. With a bit of patience and puzzle solving skills, you can easily unlock the door and progress further in the game.

The North Hall door puzzle in the Astronomy Wing of Hogwarts Legacy is a tricky one to solve.
