Where Is The Trading Post Puzzle Box?

The Trading Post puzzle is located in the Trading Post, a unique Outer Room that you can only draft if you have unlocked the West Gate. To unlock the West Gate, you must figure out how to open the Garage Door, which leads to the other side of the gate and allows access to the Outer Room.

The Trading Post is one of many possible floorplans that are unique to the Outer Room. The Trading Post is a place where you can exchange one item for another, but if you look on a bench in the back left corner of this room, you’ll find a peculiar puzzle box.

How To Solve The Trading Post Puzzle

Secret Trading Post Puzzle Box Solution

The Trading Post puzzle takes the form of a small puzzle box that can be found in the back corner of the Trading Post. This innocuous 3×3 grid looks similar to other box puzzles (like the secret Tunnel box puzzle), but each box is different and requires a different approach.

The one thing that is consistent between all Blue Prince puzzle boxes is that you must move a specific color into each of the four corners of the grid. Once you have aligned the required colors correctly, you must click the mountain symbol on each corner to lock in and solve the box puzzle.

In this case, you must move the yellow tiles into each of the four corners.

• If you click the purple tile, the surrounding tiles will rotate.
• If you click the tile above or beneath the purple tile, the purple tile will move into that spot.
• The purple tile cannot move horizontally​​​​​​, it can only move up and down.
• If you click a yellow tile, it will move up one space.
• Yellow tiles cannot move down.

Essentially, your goal with this puzzle is to move a yellow tile into each corner, with the purple tile in one of the middle slots on the outer row so it is out of the way. To solve the Trading Post puzzle, Blue Prince players should follow these steps:

1. Click the purple tile (1-3) to rotate the middle yellow tile to the left
2. Click the middle left yellow tile (1-2) to swap its position with the purple tile
3. Click the bottom middle yellow tile (2-1) to move it into the middle space
4. Click the purple tile twice to rotate the two surrounding yellow tiles
5. Click the middle yellow tile (2-2) to move it up one space
6. Click the purple tile once to rotate the surrounding yellow tiles
7. Click the middle yellow tile (2-2) to move it up one space
8. Click the purple tile four times to rotate the surrounding yellow tiles
9. Click the yellow tile on the middle right (3-2) to move it up one space
10. Now that the corner tiles are yellow, click each mountain symbol in the corners of the box to solve the Trading Post puzzle
