In this guide, we’ll explain how you can complete all eight of the Sanctum Sigil puzzles in Blue Prince. This will help you to reach Room 46.

The Sanctum Sigil puzzles are eight puzzles that are in the same location in Blue Prince. You’ll get to these puzzles after spending several days in the game. But completing these puzzles isn’t crucial if you just want to progress toward the mysterious 46th room in the Mount Holly estate.
In this guide, we take a look at how you can solve the Sanctum Sigil puzzles in Blue Prince. We’ll also tell you where and how you can find these puzzles in the game.
Where Are the Sanctum Sigil Puzzles in Blue Prince?

The Sanctum Sigil puzzles are in the Inner Sanctum area of the Underground. From this room, you’ll have to head downwards to activate the last lever for the Antechamber, which paves the way for Room 46. Surrounding the lever will be eight doors that take you into eight different rooms. All of them will house a Sanctum Sigil puzzle that you need to solve.
Keep in mind that for every door, you’ll need specific Sanctum Keys. You can find one of the keys in the Inner Sanctum the first time you visit. On your next visit, you’ll discover clues for all other Sanctum Keys in the form of poetry. Don’t worry, the poem makes the location of the other keys quite apparent.

How To Solve the Eight Sanctum Sigil Puzzles in Blue Prince?

Before solving the puzzles, you’ll need to understand how they work. Every room has a huge dial that controls the movement of different parts of the mechanism at the back of the room. The mechanism has a symbol at its center. Here’s how the dials and the mechanism work together.
- The top dial changes the shapes on the innermost portion.
- The second dial will affect the dividing rays.
- The third dial controls the number of rays and motes present.
- The fourth dial changes the symbols on the outermost border.
After setting the correct pattern, you will have to click the button in the middle of the dials.
Keep in mind that if you want to solve the puzzles organically, you’ll need to discover clues for each one all across the manor. Now, let’s take a look at individual Sanctum Sigil puzzle solutions, starting from the doors on the left and going right.
Puzzle Number | Inner Symbol | Divider Symbol | Boundary Symbol |
1 | 5x chips | 3x Byzantine crosses | Alternating small and large circles |
2 | 8x double triangles | 4x Byzantine crosses | Wavy bolt lines |
3 | 5x square boxes | 3x wavy bolts | Spiky triangular shapes |
