Unlocking the Secret of the Trading Post Puzzle Box

The Trading Post puzzle is represented by a compact puzzle box situated in the room’s back corner. This 3×3 grid resembles other box puzzles found throughout the game, yet each puzzle possesses its unique characteristics and demands a tailored approach.
A common element across all Blue Prince puzzles is the requirement to position specific colors into each corner of the grid. To complete the puzzle, players must securely lock in correct colors by clicking the mountain symbol located on each corner.
For this particular challenge, it’s crucial to maneuver the yellow tiles to occupy each corner of the grid.
- Clicking the purple tile rotates the surrounding tiles.
- Clicking the tile above or below the purple one will shift the purple tile into that position.
- The purple tile can only move vertically, not horizontally.
- Clicking a yellow tile raises it one space.
- Note: Yellow tiles cannot be moved downward.
The main objective is to get a yellow tile into each corner while positioning the purple tile in an outer row middle slot to avoid hindrance. Here is a strategic sequence to solve the Trading Post puzzle:
Column 1 | Column 2 | Column 3 | |
---|---|---|---|
Row 3 | 1-3 | 2-3 | 3-3 |
Row 2 | 1-2 | 2-2 | 3-2 |
Row 1 | 1-1 | 2-1 | 3-1 |
- Initiate by clicking the purple tile (1-3) to rotate the middle yellow tile to the left.
- Next, click the middle left yellow tile (1-2) to interchange its position with the purple tile.
- Click the bottom middle yellow tile (2-1) to shift it into the center.
- Click the purple tile twice to rotate the two adjacent yellow tiles.
- Click the middle yellow tile (2-2) to elevate it by one space.
- Click the purple tile once to rotate the surrounding yellow tiles.
- Click the middle yellow tile (2-2) to move it up again.
- Click the purple tile four times to rotate the surrounding yellow tiles.
- Click the yellow tile on the middle right (3-2) to move it up.
- Once all corner tiles are yellow, click each mountain symbol to finalize the Trading Post puzzle.
If you find yourself stuck, you can reset the Trading Post puzzle by selecting one of the corner symbols without a yellow tile. This action will revert the board to its original state.
