How To Use Gear Wrench in Blue Prince

Blue Prince is a captivating puzzle mystery game where players explore the enigmatic Mt. Holly estate, uncovering hidden secrets and solving intricate puzzles. One of the most valuable tools in your inventory is the Gear Wrench, a unique item that alters the rarity of mechanical rooms—giving you greater control over your runs.
However, using the Gear Wrench incorrectly can backfire, making certain rooms harder to find. This guide explains how the Gear Wrench works, the best strategies for using it, and which rooms to prioritize for a successful run.

What Does the Gear Wrench Do in Blue Prince?


The Gear Wrench lets you manipulate the spawn rates of mechanical rooms in Blue Prince. By adjusting their rarity, you can:
  • Increase the chances of rare rooms (like Laboratory, Pump Room, or Boiler Room) appearing.
  • Decrease the frequency of common rooms (such as Security or Utility Closet) if they’re not useful for your strategy.

This mechanic adds a strategic layer to each run, allowing you to tailor the dungeon layout to your playstyle.

Best Ways to Use the Gear Wrench


  • Boost Rare Mechanical Rooms
    • If you're aiming to solve the Mechanarium puzzle, increasing the spawn rate of rare gear-type rooms (Laboratory, Pump Room, Boiler Room) is crucial.
    • The more gear rooms you draft, the faster you progress toward puzzle completion.
  • Avoid Adjusting Common Rooms

    • Using the Gear Wrench on Security or Utility Closet rooms can make them too rare, hurting your run if you rely on them for resources.
    • If you don’t need the wrench, consider trading it at the Trading Post for a more useful item.
  • Plan Ahead for Long-Term Strategy

    • Since outcomes aren’t guaranteed, weigh the risks before using the wrench.
    • If you’re aiming for a specific room type, prioritize adjustments early in your run.

    • Should You Keep or Trade the Gear Wrench?


    If you're not focusing on mechanical rooms, trading the Gear Wrench might be the better option. The Trading Post offers valuable alternatives that could better suit your playthrough.


    However, if your goal is to uncover Room 46 or complete the Mechanarium puzzle, mastering the Gear Wrench is essential.

    Final Tips for Gear Wrench Success


    ✅ Increase rare room spawns for Mechanarium progress.

    ❌ Avoid tweaking common rooms unless necessary.

    🔄 Trade it if you don’t need it for a more useful item.


    By using the Gear Wrench wisely, you can optimize your runs, solve puzzles faster, and uncover the deepest secrets of Mt. Holly.
