If you thought puzzles like the Room 46 or the West Gate are tough to handle, then you have no idea what else is stored in Blue Prince. There are so many puzzles and a lot of them are not even part of the game’s main story. Some puzzles are part of the game’s world, puzzles like the 4 Blue Flames at outside the manor.
There are 4 flames and the game, as expected, doesn’t do a good job explaining what to do here. The short answer is that you light it up. All 4 Blue Flames can be activated but how? And what happens when you do? Here are is quick on how to activate all 4 Blue Flames.
How to Light All Blue Flames in Blue Prince
To activate all Blue Flames you need to find the locations of the four gas switches in the game. Once you activate all four of them, the four flames will light up but none of the switches are inside the manor. The switches we are looking for are in the Apple Orchard, Gemstone Cavern, Schoolhouse, and Hovel.
Apple Orchard Gas Switch
The first gas switch is inside the Apple Orchard but to open the gate to the orchard you need the code to the combination lock. The combination to the lock is 1128. If you want to get the code yourself you can, use the Magnifying Glass on the picture in the Dark Room.
The light to the dark room is turned on by the switch in the Utility Room.
Gemstone Cavern Gas Switch
Near the Apple Orchard is a mechanical door that is locked. The door leads to the Gemstone Cavern and inside you will find a VAC Indicator label unit. The lights here need to be in the following order off, blue, green, white, red, purple to unlock access to the Gemstone Cavern.
Inside the Cavern you will find the second gas switch. Now two Blue Flames should be activated outside the manor.
Hovel and Schoolhouse Gas Switches
Hovel and Schoolhouse gas switches are found after you draft these rooms in the Outer Room slot. But first you need to find the Utility Closet and Garage in the Manor. Press the switch in the Utility Room to open the Garage and then go outside.
Follow the path outside to get to the door to the Outer Room where you can draft Hovel, where another Gas Switch is waiting for you.
The final gas switch is in the Schoolhouse which is another room you can draw in the Outer Room.
What Happens When All Four Flames Are Activated?
The flames burn and when they do an elevator appears outside the manor that takes you down to the Underground area. This is the area where one of the Upgrade Disks is found and there other puzzles you can interact with.
