Blue Prince holds plenty of secrets, they are not easy to find. They are well hidden and will require us to solve the specific puzzle to unlock them. One of the mysteries revolves around turning four Blue Flames. The valve that turns on the flame is locked in four different locations in the game. Here we are going to look at all the Blue Flame locations in Blue Prince.
All Blue Flame locations In Blue Prince
You will need to turn on four gas valves to light four Blue Flames. Each of them has an inside that is hidden from the player. You must solve a puzzle to gain access to them. There is no order attached to the gas valves, you can turn the valves on in any order. A cutscene will trigger after you turn on a single gas valve, indicating your progress.
First Blue Flame Location | Apple Orchard

Objective: The first gas valve for the Blue Flame is found inside the Apple Orchard east of the Manor entrance.
The door to the orchard will be locked, and we need to figure out the key code to open it and turn on the gas valve to light up the first Blue Flame.
- Take the path right of the Manor, then take a right turn, head straight, and lastly take the path left of the tent in the Campsite. It will lead you to the Apple Orchard. The door will be locked, and you can only open it by inserting the correct four-digit number.
Puzzle Solution: Head to the Dark Room, and interact with the photos in the corner of the room. Use your magnifying glass on the photo to see the number left of the picture. You will find the code 1128 written inside a heart-shaped mark. Head inside and you will find a yellow pipe on the left next to the white picket fence. Interact with it to unlock the first Blue Flame.
Second Blue Flame Location | Gemstone Cavern

Objective: You will find the gas valve for the second Blue Flame in Gemstone Cavern, found east of the Manor’s entrance.
Unlocking the Door to Gemstone Cavern
The door to the Gemstone Cavern remains locked; we can unlock it by solving a puzzle in the Utility Closet.
Utility Closet: You can find the closet near the Hallway.
- Head to the Utility Closet and solve the Breaker Box puzzle. Here, you will have six light bulbs under the V.A.C. Indicator, you need to make sure all the light indicators are arranged in a specific color order.
“Gray/ Blue/ Green/ White/ Red/ Purple”
- Once you have solved the puzzle, the wall behind the machine will lift up. Head inside and pull down the lever to unlock the door that leads to Gemstone Cavern.
Gemstone Cavern Location: Take the path right of the Manor, keep heading straight, turn right, and you will eventually find the entrance to Gemstone Cavern door amongst the rock.
- Head inside the cavern, and you will find the pipe on the right side. Interact with it to unlock the second Blue Flame.
Third and Fourth Blue Flame Location| Hovel and Schoolhouse

Objective: The last two gas valve locations for turning the Blue Flame can be found in the Outer Room by Drafting Hovel and School House.
RNG is part of the selection pool, so unlocking a shortcut to the Outer Room Via West Gate will be a much more appropriate way to deal with the last two Blue Flames. This will allow us to gain access to the Outer Room spot from the Manor Entrance location, through the west gate, directly guiding us to the Outer Room at the end.
Unlocking the West Gate Route via Garage
Here we unlock the garage door to open up the gate right of the Manor that leads us to the Outer Room.
- Go to the Utility Closet, interact with the V.A.C. Indicator machine, and here at the bottom, you will come across a switch with the word Garage next to it. Flip the switch to unlock the Garage.
- Now navigate to the Garage area, here press the button on the switch board found next to the door. This will open up the Garage doors. Get out of the garage by heading through the Garage door, and you will soon be on the West path. Here, head straight and then quickly take a left turn.
- Follow the road, walk across the wooden plank, and lastly turn left to get to the West Gate. Now turn back and head straight, and you will find the Outer Room.
- Now you have to select Hovel and Schoolhouse from the Outer Room selection. Everything is random in the Outer Room, you might not see Hovel or the Schoolroom in the option.
- Here, you need to interact with the Outer Room until you draft Hovel for the third Blue Flame and Schoolhouse for the Fourth.
Since we have unlocked the route to the Outer Room through the West Gate, directly left of the Manor entrance. You will have an easier time getting to the location than before.
