Hogwarts Legacy

Hogwarts Legacy is home to many secrets. Finding them and solving them is exciting, to say the least. Puzzles range from simple to complicated, with door puzzles lying on the more challenging side of things. They may appear confusing to some individuals, even after the first few attempts.

Some players attempt to brute force all 12 puzzles, trying every possible combination until they succeed, but it takes the fun out of everything. In this guide, you’ll learn the correct way to solve the door puzzles. Also, the rewards are random, so it’s better not to have any specific expectations. With that out of the way, let’s begin.

How to solve the the Hogwarts Legacy Door Puzzles

You should know that the key to solving the door puzzles is simple math. There will be two equations etched on the door, each with a number in the middle, followed by three outer circles connected by a triangle. The central number is the sum of all the outer numbers. The first number is already revealed. You can identify the second number from the symbol. Now subtract their sum from the middle value. The solution should be within 0-9.

Identify the symbol corresponding to the new number and toggle the dials until you have those symbols in sight. The left dial is for the first equation, while the right dial is for the bottom equation.

You can find the note that explains all the animal numbers at the first puzzle door’s location. In case you’ve missed it, here is the list:

0 – Furry Creature with eyebrows

1 – Unicorn

2 – Tentacle Goat

3 – Three-headed Snake

4 – Weird Owl

5 – Spider with a Face

6 – Lizard

7 – One-eyed Squid

8 – Spider

9 – Hydra

It’s better if you take the time to solve the puzzles yourself. They are not that difficult once you know the secret, which you now do. However, if you’re in a hurry to complete the campaign, you’ll find all the solutions to the door puzzles listed below.

Door Puzzle #1: Central Hall Rafters
