How To Find the Tunnel Floorplan in Blue Prince

Blue Prince is a game filled with mysteries, puzzles, and hidden secrets, one of which is the Tunnel floorplan—a unique room that allows players to draft a sequence of connected Tunnel rooms, forming a straight pathway. Additionally, it hides a secret Mora Jai puzzle at the end, adding an extra layer of intrigue.
Unlike some other Found Floorplans that require complex puzzle-solving or deciphering clues, the Tunnel floorplan is relatively easy to acquire. However, you will need a specific tool to access it. This guide will walk you through everything you need to know about locating and unlocking the Tunnel floorplan in Blue Prince.

What Are Found Floorplans?

Before diving into the specifics of the Tunnel, it’s important to understand Found Floorplans. These are special room blueprints that are not initially available in the drafting pool. Some can be unlocked via the Drafting Studio, while others must be discovered in the game world.
The Tunnel is one such floorplan, and once obtained, it allows you to incorporate a sequence of Tunnel rooms into your drafts, creating a straight path with a hidden puzzle at the end.

Where to Find the Tunnel Floorplan

The Tunnel floorplan is located in the Grounds, just outside the main house. Here’s how to reach it:

Head downstairs from the starting area to the outdoor section (the Grounds).

Look for the entrance to a dark tunnel—this is where the floorplan is hidden.

The tunnel is initially too dark to navigate, meaning you’ll need a light source to proceed.

How to Illuminate the Tunnel

Since the tunnel is pitch-black, you’ll need one of two items to light it up:

Option 1: Self-Igniting Torch

• Where to Get It: Purchase from the Armory.
• How to Unlock the Armory: Solve the chess puzzle and choose the "Power of the Knight" reward.

Option 2: Burning Glass

• How to Craft It: Combine a Metal Detector and a Magnifying Glass at the Workshop.
• Where to Find the Components:
  • The Metal Detector can be found in various locations, often in storage rooms or hidden areas.
  • The Magnifying Glass is usually obtainable early in the game, possibly in the study or library.

Once you have either the Self-Igniting Torch or the Burning Glass, follow these steps:

Enter the tunnel in the Grounds.

Walk forward until you’re blocked by wooden crates.

Look back slightly—you’ll see torch holders on the walls.

Use your Torch or Burning Glass to light the torches, which will illuminate the entire tunnel.

Once the area is lit, you’ll notice the Tunnel floorplan placed on top of the wooden crates.

Pick it up, and it will be permanently added to your drafting pool!

Why the Tunnel Floorplan Is Worth Getting

The Tunnel is not just another room—it has unique gameplay benefits:

• Creates a Straight Pathway: Unlike most rooms that branch out, the Tunnel allows for a linear sequence, which can be useful for strategic drafting.
• Secret Mora Jai Puzzle: At the end of the Tunnel sequence, you’ll encounter a hidden puzzle, rewarding observant players.
• Easy to Obtain: Compared to other Found Floorplans, the Tunnel is one of the simplestto unlock since it doesn’t require solving complex riddles.

Tips for Using the Tunnel in Drafting

Once you’ve added the Tunnel to your draft pool, consider these strategies:

• Use it as a connector between key rooms, ensuring a direct path without unnecessary detours.
• Combine it with defensive rooms to create a controlled pathway, forcing encounters in specific areas.
• Explore the Mora Jai puzzle—solving it may yield rare rewards.

Conclusion

The Tunnel floorplan in Blue Prince is a valuable addition to your drafting options, offering both utilityand hidden secrets. By following this guide, you can easily locate andunlock it using either the Self-Igniting Torch or Burning Glass.

Now that you’ve secured the Tunnel, experiment with different draftingstrategies and uncover the secrets hidden within its depths. Happydrafting!
