Locating Hidden Tunnel Puzzle


The Secret Tunnel Puzzle is not something that you would stumble upon by accident. To find it, you will first need to unlock the floor plan of the tunnel. To do so,

• Head out through the Entrance Hall and follow the pebbled path.
  
• Descend white staircase.
  
• At the bottom, take the right and find the dark passage blocked by the crates.
  
• Bring the Burning Glass with you. Without it, you will not be able to progress.
  
• Inside the passage, light 1 of the 2 torches at least. It will reveal a Secret Tunnel blueprint at the far end.
  
• Next, draft the tunnel into the perimeter of the mansion when you plan the next expansion.
  
• After it’s built, venture in to find the puzzle box at the end.
  

If you have tackled the Trading Outpost puzzle before, you must know that this puzzle follows similar mechanics. However, it comes with a twist of orange tiles that fill all four corners.



Master the mechanics to solve Secret Tunnel Puzzle




Before you dive into the solutions, it’s better to know how the puzzle works.

• The purple tiles can rotate the nearby purple titles when they are clicked.
  
• The orange tiles are only important when they get sandwiched between 2 purple tiles. They can then turn the purple ones.
  
• The black tiles shift the entire row rightwards while looping the tiles back to the left end.
  

Now, when solving the puzzle,

• Click on the black tile, and it will move to the center, with the purple tile moving in place of the black tile.
  
• Again, click on the black tile, and it will move to the right.
  
• Next, click on the purple tile, and the black tile will move a grid down to come to the mid-right end of the grid.
  
• Click on the black tile again, and it will move to the extreme left end.
  
• Then click on the purple tile on the left end, downwards. It will shift the black tile to the middle.
  
• Click on the purple tile again, and the black tile will come right beside it at the lower end of the grid.
  
• Then click on the black tile, and it will move rightwards while the left-end purple tile will shift in the middle.
  
• Click on the purple again, and the black tile will appear on the left-hand corner of the grid.
  
• Click on the purple tile until the black tile comes in the middle. The middle section of the grid will look like a sandwich, with purple tiles on both ends and black tiles in between.
  
• Clicking first on the heart-shaped arrow present on the left end downwards, click the heart present on the top end’s left side.
  
• Move to the right end and click the heart again, and then click on the one heart— the heart presents the extreme right of the grid, downwards.
  
• With these steps followed correctly, you will be able to open the box.
  

After the puzzle is solved, you will be able to get the Allowance Token. It will boost your daily gold by +2 coins, starting just the next day.



Why is this puzzle important?

Unlike the one-time loot, the Allowance Token comes with some lasting benefits. It makes the future runs easier. As Blue Prince completely thrives upon resource management, some extra starting gold means the difference between the struggle for funds and early upgrades. Also, uncovering the secrets, like the secret tunnel puzzle, reinforces the theme of exploration and discovery within the game, ensuring all hidden rooms/puzzles hold some game-changing rewards.


Now that you are aware of the tunnels’ secrets, light the torches and draft wisely. Claim the prize before you move ahead.
