Blue Prince is a fantastic roguelike puzzle adventure that was eight years in the making, and over the past few weeks, I’ve sunk more than 80 hours into the game. As well as my review of the game —where I compared it to Cyan Worlds’ Riven — I’ve been putting together some Blue Prince video guides on the Postmode YouTube channel, which you should subscribe to if you haven’t already.
In this article, I’m going to create an evolving hub for all of Postmode’s Blue Prince guides, so you can get help with tackling some of the trickier puzzles in the game. This will be an evolving document, and I’ll continue to add more video guides as I produce them. Sound off in the comments if there are any particular guides you’d like to see. I’m still nowhere near finished with the game, so there’ll be more to come in the near future.

How to unlock the Blackbridge Grotto Admin terminal
The video guide outlines how to find the admin keys for Anne Babbage, Kimberley Thompson and Randolph Moore, but there are also three ‘delisted’ admin keys in Blue Prince that I’m yet to find. Click the arrow below if you just want to see the answers.

How to get the Paper Crown in the Closed Exhibit
The Found Floorplan for the Closed Exhibit is in the Study safe, and we have a separate guide to unlocking that which you should tackle first before you try and steal the Paper Crown.
All Microchip locations and how to unlock the Throne Room
Finding the microchips in Blue Prince involves purchasing A New Clue from the Bookshop, a floorpan that can only attach to the Library floorpan. From there, you need to check the book out and scour its pages for clues.
Blue Prince Corner Case Microchip Clues
Patio – Buried
Nook – Beside
Office – West
Pantry – Bridge
All Antechamber Levers in the Secret Garden
As well as the lever that you can reveal by messing with the weathervane wheels, there’s a breakable wall in the Secret Garden that you can knock through with the Power Hammer to access a hidden Antechamber Lever.

Sledgehammer, Battery Pack and Broken Lever
How to get the File Cabinet Key in Blue Prince
If you drain the Aquarium with the Pump Room, you can find some dioramas in the former fish habitats that reflect certain rooms in the manor. If you follow the clues outlined in the video above, you’ll acquire a File Cabinet Key, which will lead you towards an Upgrade Disk and an important lore note.
How to find the Antechamber Lever in the Great Hall
This guide will show you how to interpret the Partioning Plan in the Drafting Studio to divine the layout of the Great Hall on a per-day basis. You can use this information to confidently secure a path to Room 46, without wasting too many keys.
How to solve the Clock Tower Sanctum Key puzzle
Once you roll credits in Blue Prince, the next big task will involve securing several Sanctum Keys that are strewn throughout the manor. The Clock Tower puzzle is perhaps the trickiest, asking you to idle in a room until 1:30 PM to reveal a secret passage, and a complicated clockwork puzzle.
Blue Prince Clock Tower Puzzle Memo Rules
EACH OF THESE CLOCKS SHOULD BE SET TO A DIFFERENT TIME (Blue = True)
FIVE OF THESE CLOCKS SHOULD BE SET TO A TIME ENDING ON THE HOUR (Blue = True)
SET THIS CLOCK TO A TIME CONTAINING ALL DIFFERENT NUMBERS (Red = False)
THIS CLOCK’S NEIGHBOURS SHOULD BE SET TO A TIME CONTAINING A 7 (Blue = True)
THIS CLOCK SHOULD NOT BE SET ON THE HOUR – ENDING :00 (Red = False)
NONE OF THE CLOCKS SHOULD BE SET TO TIMES THAT CONTAIN 1, 2, 3 OR 4 (Blue = True)
THIS CLOCK SHOULD BE SET TO A TIME THAT CONTAINS THE SAME THREE NUMBERS OF ANOTHER CLOCK, BUT IN REVERSE (Blue = True)
THE CLOCKS ARE POSITIONED SO THAT THEIR TIMES WILL GO UP IN ASCENDING ORDER (Red, but it’s handwritten = True)
How to solve the Mechanarium Sanctum Key puzzle
If you’re looking for the location of the Mechanarium Found Floorplan, you’ll find it as part of the rotating gear puzzle in the underground which allows you to access the Sealed Passage. The floorpan is hiding in one of the optional nooks you can access by rotating the gear mechanism. The associated Sanctum Key puzzle involves drafting seven Mechanical or ‘Cog’ rooms in the manor, and then placing down a Mechanarium. You can use the Chamber of Mirrors floorpan to allow for duplicate cog rooms to spawn.
Blue Prince Mechanical Rooms
Utility Closet, Boiler Room, Pump Room, Security, Workshop, Laboratory, Electric Eel Aquarium (Upgrade Disk Reward)
How to solve the seventh Sanctum Key puzzle
The seventh Sanctum Key in Blue Prince arrives with a clue: “The seventh is major if you draft it quite late.” It’s tricky to know whether late means late in the day or late in the ranks (as in, the furthest reaches of the grid). To put your best foot forward, Alt-Tab at the start of the day and leave the game running until it’s dark out, and then use Ivory Die to preroll your Music Room drafts until the later parts of the manor grid.
All Workshop Contraption recipes in Blue Prince
One of the trophy challenges in Blue Prince involves crafting each upgraded tool or Contraption, at the Workshop. You need to complete eight trophies to unlock the ability to purchase the Blue Tents upgrade from the Mt Holly Gift Shop, and this is one of the easier challenges to complete.
