The Complete Guide to Blue Prince’s Trading Post: Puzzle Box, Dynamite & Trading Mechanics

Hidden deep within the Outer Rooms of Mt. Holly, the Trading Post is more than just a place to swap items—it’s a puzzle hub, resource center, and secret vault all rolled into one. Whether you’re aiming for permanent upgrades, unlocking hidden rooms, or optimizing your late-game economy, mastering the Trading Post is essential.

Updated for 2025, this guide covers unlocking the location, solving the Mora Jai puzzle box, blowing through hidden walls with dynamite, and trading mechanics so you can maximize every run.


🔓 How to Unlock the Trading Post Permanently

The Trading Post doesn’t appear automatically—you must unlock it first:

  1. Power the West Gate: Draft the Utility Closet and solve the Breaker Box puzzle to power the Garage.

  2. Draft the Garage: On your next run, place the Garage. Exiting leads to the West Gate Path.

  3. Cross the Bridge: Follow the path to the Outer Rooms door.

  4. Permanent Unlock: Interacting with this door permanently adds the Outer Rooms to your draft pool. The Trading Post will now randomly appear as an option.

Pro Tip: The Trading Post isn’t guaranteed each run. Prioritize drafting Outer Rooms when available if your goal is to visit it.


🧩 Solving the Mora Jai Puzzle Box

Blue Prince, Trading Post Puzzle Box

At the center of the Trading Post, you’ll find a Mora Jai puzzle cube. This is not just color-matching—it’s a logic-based challenge.

Objective

Place a yellow square in each of the four corners of the cube.

Mechanics

  • Yellow squares: Tap to move them upward by one space

  • Pink square: Rotates three adjacent yellow squares counter-clockwise

  • Grey squares: Empty, cannot be interacted with

Step-by-Step Solution

  1. Tap the yellow square in the middle row, far-right column

  2. Tap the pink square twice

  3. Tap the yellow square in the middle row, far-left column

  4. Tap the yellow square in the bottom row, middle column twice

  5. Tap the pink square four times

  6. Once all four corners are yellow, press the four mountain symbols on the cube corners

🎁 Reward: The box opens, granting an Allowance Token that permanently increases your daily coin allowance by +2 coins.


💥 Using Dynamite to Unlock the Hidden Distillery

The Trading Post holds another secret—a hidden Distillery behind a cracked wall.

Steps:

  1. Find Dynamite: Most reliably in the Vault

  2. Light the Fuse: Use a Burning Glass or Self-Ignited Torch (regular torches won’t work)

  3. Blow the Wall: Place the lit dynamite to reveal the hidden Distillery

Distillery Loot

  • Upgrade Disk: One-time

  • Coins: 40 (chest respawns in future visits)

  • Still Water: Key item for late-game puzzles


🔄 Trading Mechanics Explained

Contrary to popular belief, the Trading Post does not use a barter system based on item “value”. It operates on fixed hidden lists for each item.

How It Works

  • Place an item on the trading table

  • The game cycles through a predetermined list of possible trades

  • You can reject offers to see the next one

Item Tier System

  • Low-Tier Items: Common Keys, Stones → low-tier resources

  • Mid-Tier Items: Silver Keys, Gems → Upgrade Disks or useful tools

  • High-Tier Items: Gold Keys, Sanctum Items → rare rewards, permanent stat increases

Strategic Tip: High-tier items may require cycling through multiple offers to find the best trade. Use community-discovered trade lists for optimal results.


💎 Summary & Key Takeaways

  1. Unlock Once: Reach the Outer Rooms via Garage + West Gate Path

  2. Solve the Puzzle Box: Follow steps to earn the permanent Allowance Token (+2 coins/day)

  3. Explode the Wall: Use Dynamite + Burning Glass to access the hidden Distillery (coins, Upgrade Disk, Still Water)

  4. Trade Smart: Understand fixed lists and tiers; don’t risk valuable items without research

Mastering the Trading Post is a major step toward a wealthy, efficient estate in Blue Prince. With this guide, you’re ready to solve puzzles, uncover hidden secrets, and trade your way to greatness.
