Originally posted on Total Apex Gaming | By Mollie Dominy | Last updated May 24, 2025 12:22 AM ET

If you’ve been exploring the sprawling, mystery-soaked halls of Mount Holly Estate in Blue Prince, then you’ve probably stumbled into one of the game’s most useful resources—Green Rooms. But what are they exactly? And why are so many players building strategies around them? Let’s break it down.

Green Rooms: Not Just for the Vibes

In Blue Prince, Green Rooms are more than just pretty gardens or courtyards—they’re a core strategic tool. These rooms, marked by green borders, tend to be outdoor-themed and are heavy on resources. Think fruit trees, dig sites, and handy tools like shovels that make these rooms pay off big time.

What makes them even more valuable is how they chain together. Certain rooms, like the Greenhouse, increase your chances of seeing more Green Rooms in future drafts. Others like the Patio spread gems to all other Green Rooms. Suddenly, you’re not just building a path to the antechamber—you’re growing potentially resource-rich areas that can help you not get stuck behind a locked door.

What Each Green Room Does

Here’s a handy breakdown of confirmed Green Rooms and what they bring to your run: Not every room is created equal, but nearly all of them offer passive or active bonuses that can supercharge your run if you’re paying attention.

Room Name	Type	Rarity	Effect	Gem Cost
Terrace	Green Room, Dead End	Standard	Prevents all Green Rooms from costing gems	0
Patio	Spread, Green Room	Standard	Spreads gems throughout all Green Rooms	1
Courtyard	Green Room	Standard	Mostly decorative, but can potentially hold key items	1
Cloister	Green Room	Unusual	Rare and scenic tied to some Mt. Holly secrets	3
Veranda	Green Room	Unusual	Increases item find rates in Green Rooms	2
Greenhouse	Drafting, Green Room, Dead End	Standard	Boosts chances of drafting more Green Rooms	1
Morning Room	Tomorrow, Green Room	Rare	Has 2 gems. Gives you 2 gems on the following day	0
Secret Garden	Spread, Green Room	Rare (conditions must be met)	Spreads fruit throughout the estate	0

Upgrade Needed

If you’re able to find the upgrade disks that are scattered throughout the manor, always make sure to check what it is in one of the 3 computers in the game (Laboratory, Office, or Shelter). Some of those disks can upgrade certain rooms, including Green Rooms, from which you’re able to change the resources gained from those rooms.

Why Green Rooms Are Worth Drafting

Green Rooms aren’t just set dressing—they’re your best bet at staying supplied, unlocking secrets, and increasing your odds of making it to the elusive Room 46. They’re often packed with puzzle potential, story threads, and some of the most resource-rich opportunities in the game.

Whether you’re hoarding gems, solving environmental mysteries, or looking to build out a lore-heavy estate path, Green Rooms give you the tools to do it.

Green Rooms are a sleeper-hit mechanic in Blue Prince—easy to overlook, but impossible to ignore once you realize how much value they bring. With the right combo of rooms and a little forethought, you can turn your estate route into a strategy masterclass.
