Foundation & Starting Rooms
Welcome to your humble beginnings. These rooms never change and give you a consistent start every day—your base of operations in the madness of Mount Holly.
The Foundation
This is the only room that never resets. It’s your safe zone and always there, no matter what happens in your run.
Entrance Hall
You start here every day. It’s the front porch of your suffering.
Basic Blueprint Rooms
These are the bread and butter of your exploration. Some hold puzzles, some hold loot, and some are just glorified hallways with furniture.
Spare Room
A nothing-special room. No tricks, no puzzles, just there.
Rotunda
Costs 3 gems. It’s one of the few rooms that can rotate, which can help solve certain puzzles. Useful, but expensive.
Parlor
Has its own puzzle. You’ll need to solve clues inside the room to unlock a reward.
Billiard Room
Another puzzle room. The math changes every day, so don’t get comfy with just one solution.
Gallery
Rare puzzle room. Comes with a painting-based puzzle to solve.
Room 8
It’s a rare puzzle room. The name is boring, the challenge isn’t.
Closet
Dead end with two items. Usually something useful, sometimes just more junk.
Walk-in Closet
Dead end again, but this one gives you four items instead of two. Slightly fancier storage.
Attic
Costs 3 gems. Big stash: eight items inside. It’s a dead end though, so plan ahead.
Storeroom
Has a set of three things: 1 key, 1 coin, 1 gem. A classic “free stuff” stop.
Mail Room
Costs nothing, but delivers a random item tomorrow. Great if you’re patient. Useless if you forget it exists.
Resource Rooms
These rooms exist to fatten your wallet—whether it’s coins, gems, or keys. Plan your paths to hit a few of these if you want to avoid running out of stuff.
Nook
Contains a single key. Pretty standard. Not bad to stumble into.
Garage
Dead end, but has 3 keys inside. You’ll need it to open up the West Gate later on, so it matters.
Music Room
Costs 2 gems. Comes with a major and a minor key. Not a puzzle room, just a music-themed loot room.
Locker Room
Spreads keys around the house. You’ll need a gem to draft it, but it helps in the long run.
Den
One gem inside. Simple and not rare.
Wine Cellar
Dead end. Has 3 gems. Good for stocking up early if you’re lucky.
Trophy Room
Costs 5 gems, but gives 8 back. Great deal, but only if you can afford the entry fee.
Ballroom
Every time you enter, your gem count gets reset to 2. Plan carefully if you’re hoarding gems.
Pantry
You’ll find four coins here. Just coins, nothing fancy.
Rumpus Room
Costs 1 gem. Gives you 8 coins and usually has Alzara the fortune-telling robot.
Vault
Costs 3 gems. Has 40 coins inside and locked deposit boxes. Worth it—if you have a Vault Key.
Office
Coins get “spread” around your estate after entering this room. Think of it like passive income.
Drafting Rooms
These rooms mess with the Drafting Pool itself. That means more rerolls, rarer finds, or straight-up new rooms. Good if you’re hunting something specific.
Drawing Room
Lets you redraw one draft pick per exit. Good for re-rolling your options.
Study
Lets you pay gems to redraw floorplans up to 8 times. Pricey, but powerful.
Library
Increases your chance of getting rarer room options.
Chamber of Mirrors
Allows you to draft duplicate rooms, including ones already placed. Very useful for tricky puzzles.
The Pool
Adds the Locker Room, Sauna, and Pump Room to today’s drafting pool.
Drafting Studio
Lets you permanently add a new room to your drafting pool. Costs 2 gems.
Mechanical Rooms
These are the techy rooms. They power things, connect ducts, or just cause chaos. Think levers, puzzles, and control panels.
Utility Closet
Contains the breaker box. Lets you toggle power to keycard doors, garage, gym, and more.
Boiler Room
Powers connected rooms like the Pump Room. Has ducts that link through specific wall paths.
Pump Room
Controls water flow for places like the Fountain, Aquarium, Kitchen, Pool, and Reservoir.
Security
Shows every item you’ve stashed or found so far. Also lets you change electronic door frequency.
Workshop
Combines two items into something new, like a burning glass or shovel upgrade.
Laboratory
Lets you trigger strange effects, like puzzle resets or other room-altering mechanics.
Bedrooms
All about steps. If you’re constantly running out of movement, these rooms are your recovery stops.
Bedroom
You gain 2 steps when entering. Very basic and very handy.
Boudoir
Just a room. Sometimes used for puzzle interactions.
Guest Bedroom
A dead end. No special perks.
Nursery
Whenever you draft a Bedroom, you gain 5 steps. Great to chain into step economy.
Servant’s Quarters

Bunk Room
Counts as two bedrooms. Solid step economy.
Her Ladyship’s Chambers
Buffs Boudoirs and Closets the next time you enter one.
Master Bedroom
Grants steps equal to the number of rooms you’ve drafted. Big value late-game.
Nurses Station
If you have less than 10 steps when you enter, set it to 20. Keep up the exploration!
Hallways
These keep the estate connected. Pick the right ones to keep your paths open and flowing.
Hallway
Your generic connector.
West Wing Hall / East Wing Hall
These only appear in their specific edges of the estate.

Passageway
Costs 2 gems to draft. Useful, but expensive.

Maid’s Chamber
