When you step into Room 46 for the first time within Blue Prince, you might have already gained access to the Blackbridge Grotto, a persistent feature that allows passage to Terminals across Mount Holly Estate. In the heart of this location, you’ll stumble upon an altar-like structure where you are instructed to insert a Microchip.
In the game Blue Prince, Microchips are scarce and locating each Microchip can be challenging without cross-referencing multiple hidden notes within the game. This guide will show you where to find every Microchip, the steps required to collect each one, and the purpose of these Microchips in the game’s main areas.
What Are Microchips For In Blue Prince?
In the game “Blue Prince“, you won’t realize where to find Microchips until you open the Blackbridge Grotto, a permanent feature on the east side of the Estate. Inside this grotto, there is a device capable of holding up to three Microchips in the center of the room, facing a large metal door.
Should you manage to locate and retrieve the trio of Microchip positions, then return them to this device, the metallic gateway will unfasten, providing long-term entrance to an unexplored part of the premises – the enigmatic Orindian Ruins.
Once you insert a Microchip into the Blackbridge Grotto device, it will remain in that position until it’s manually taken out. Similarly, once you open the Orindian Ruins, they will stay unlocked on a permanent basis.
Microchip Location 1: Blackbridge Grotto
Blackbridge Grotto Already Has One Microchip Installed

As soon as you step into the Blackbridge Grotto, your eyes are drawn to a Microchip puzzle situated directly in the middle of the room. Initially, one of the slots in this puzzle is already occupied. Consequently, you’ll need to locate just two more Microchip spots within the game called “Blue Prince“.
To open Blackbridge Grotto, first, energize the Lab from the Boiler Room. Afterward, tackle the lever mystery situated across from the Lab’s terminal. Look for clues hidden within the Periodic Tables in that same room, which should provide a hint to crack the lever puzzle solution.
Upon finishing this puzzle, it will open the pathway to the Blackbridge Grotto, located north of the east gate which ultimately leads back to Simon’s encampment.
Microchip Location 2: Entrance Hall
Break A Vase In The Entrance Hall To Find A Microchip Location

Once you uncover the location of Blackbridge Grotto, it will lead you to finding the other two Microchip sites within the House and the Estate’s grounds. The initial, and most straightforward one, can be found right within the Entrance Hall itself.
- Acquire a Sledgehammer
- Go back to the Entrance
- Target the bottom of the west-side vase, on the left side as you enter via the front door
- Destroy the Vase to find a Microchip inside
After getting hold of the Microchip, promptly return to the Blackbridge Grotto and insert it into the device there. Alternatively, you could exchange it for other goods at the Trading Post; however, you’ll need to retrieve it again on a different occasion to resolve the Microchip enigma in the game Blue Prince.
Microchip Location 3: The West Path
Dig Next To The West Bridge To Find Another Microchip Location

Additionally, you have the option to locate a Microchip in the western pathway. However, please note that this specific region is accessible only after you’ve successfully opened the Western Gate on a permanent basis.
- Draft a Garage and a Utility Room
- Turn power back on to the Garage via the Breaker Box in the Utility Room
- Enter the Garage and open the Garage door with the button on the wall
- Follow the path then turn south, head through the gate, and across the wood plank
- Unlock the West Gate from the other side to permanently access this area (and the Outer Room)
After you’ve opened it, continue playing until you get a Shovel. Then, make your way back to the Western path. On the northeastern part of the bridge, near the grassy area right beside the stream, there’s a secret excavation site. Just look down to find it.
“At the Blue Prince game location, dig for the final Microchip position. This will enable you to return it to the Blackbridge Grotto to maximize your unique station’s power, witness a special scene, and unlock the Orindian Ruins – an enticing secret outdoor area.
