Secrets are lurking around every corner in the Mount Holly Estate in Blue Prince. And we don’t just mean within the manor itself but also on its grounds. For instance, there’s a tunnel just outside the manor that holds a lot of mysteries, including access to a particular puzzle that you’d want to solve.

However, reaching the puzzle and then solving it can both be tricky for many players. In this guide, we’ll explain how you can access the secret tunnel puzzle in Blue Prince. Then, we’ll help you solve it.

How To Find the Secret Tunnel Puzzle in Blue Prince?

The tunnel is a location or room that you can draft. However, for that, you’ll first need to discover the build plans for it. To get these, simply go outside from the Entrance Hall. Keep moving forward through the pebbled pathway and down the white staircase. At the base of the stairs, take a sharp right, and you’ll find a dark passageway blocked off by a number of crates. Go inside this passageway with a Burning Glass in your inventory. There, you’ll find two torches that you can light using the Burning Glass. Lighting even one of them allows you to pick up the secret tunnel floor plan at the end of this passage.

After that, you just have to draft the secret tunnel into one of the perimeter blocks of the mansion. Enter the drafted area, and at the very end of the tunnel, you’ll find the puzzle box. If you’ve attempted the Trading Outpost puzzle, this puzzle box should seem familiar to that one. However, in this one, you’ll need to move the orange tiles into all four corner squares.
