Location Discovery Strategy — How to Find All 16 Rooms

Galley House contains 16 distinct locations, each identified by a two-letter code used in the memory machine's input system. Discovering and labeling every room is essential for progression, unlocks critical scenes, and earns the Full House achievement. However, not all locations are equally easy to find. This guide provides a strategic approach to discovering all 16 rooms as efficiently as possible, with specific tips for the harder-to-find locations.

Understanding Location Discovery Mechanics

Location codes in The Incident at Galley House work differently than you might expect. You do not discover a location by physically visiting it — instead, you discover it by entering a valid scene code that references that location. When a code produces a valid scene, the location component of that code is added to your location database.

This means the key to discovering locations is entering codes. Every time you enter a code with a location you have not yet labeled, and that code produces a valid scene, you discover the location. Even incorrect codes can sometimes trigger location discovery if the location component is valid and the rest of the code is close enough.

The Two-Letter Code System

All 16 locations use a two-letter abbreviation code. These codes are generally intuitive — EN for Entrance, KI for Kitchen, CH for Chapel — but some are less obvious. The complete list of codes is:

Phase 1 — Easy Discoveries (Ground Floor Public Areas)

The ground-floor public rooms are the easiest locations to discover. Most of them appear in the first codes you enter during the investigation:

• EN (Entrance) — Discovered immediately with code 01-EN-1-11
• LI (Living Room) — Discovered with code 02-LI-1-2-3
• QU (Quail Lane) — Discovered with code 03-QU-4-5
• ST (Study) — Discovered with code 04-ST-1-6
• KI (Kitchen) — Discovered with code 05-KI-2-7
• DI (Dining Room) — Discovered with code 06-DI-3-8-9

These six locations will be labeled within the first thirty minutes of gameplay through normal story progression. You do not need any special strategy for them — simply enter the chronological codes and they will unlock naturally.

Phase 2 — Medium Discoveries (Ground Floor Specialty Rooms)

The remaining ground-floor rooms require slightly more effort:

• BI (Billiard Room) — Enter code 07-BI-5-10. This room appears in mid-game scenes.
• CH (Chapel) — Enter code 08-CH-4-11. The Chapel has supernatural significance and appears in multiple key scenes.
• WI (Wintercote) — Enter code 25-WI-9-11. This is an exterior location and one of the hardest ground-floor rooms to discover.

The Billiard Room and Chapel are found through normal story progression. Wintercote, however, is a common stumbling block. Because it is an exterior location, many players do not think to try it as a room code. If you are missing Wintercote, search for dialogue references to "the grounds," "outside," or "garden" using the keyword search tool. See the Attic and Wintercote guide for detailed strategies for finding this location.

Phase 3 — Harder Discoveries (Upper Floor Bedrooms)

The six upper-floor bedrooms are discovered later in the investigation as you uncover the personal lives and secrets of the guests:

• ED (Eddie's Room) — Discovered through codes involving Person 5 (Edmund/Eddie)
• TO (Tony's Room) — Discovered through codes involving Person 10 (Tony)
• MA (Martha's Room) — Discovered through codes involving Person 6 (Martha)
• VI (Victoria's Room) — Discovered through codes involving Person 4 (Victoria)
• HE (Helen's Room) — Discovered through codes involving Person 8 (Helen)
• OS (Oswald's Room) — Discovered through codes involving Person 3 (Oswald)

These rooms become accessible as you enter codes with higher timestamps that involve the private activities of specific characters. The key strategy is to try the character number associated with each bedroom name — for example, trying codes with character 5 (Edmund/Eddie) in various locations will eventually lead you to Eddie's Room.

Bedroom Discovery Tips

• After identifying a character, try their number in multiple locations to find their personal room
• Upper-floor rooms appear more frequently in mid-to-late game scenes (timestamps 12-22)
• Listen for dialogue where characters say "I was in my room" or "let us go upstairs"
• The keyword search tool can reveal references to specific bedrooms in unlocked dialogue

Phase 4 — The Hardest Discovery (Attic)

The Attic (AT) is the single hardest location to discover because:

• It is a hidden space above the upper floor, not a room you would naturally explore
• Its main scene (13-AT-1-4) involves the body discovery, which is a narrative turning point
• The code AT is not intuitive — most players do not think to try "attic" as a location

To find the Attic, use the keyword search tool to search for "attic," "above," "upstairs," or "rooftop" in unlocked dialogue. The hint system will also point you toward the Attic if you request hints about the body discovery. See the Attic and Wintercote guide for the full walkthrough.

Location-Based Investigation Strategy

Once you have discovered locations, use them strategically to find scenes:

Location Relevance Guide

Different locations are relevant to different parts of the mystery. Understanding which locations matter for which investigation threads helps you guess codes more effectively:

Spatial Reasoning

The layout of Galley House follows a logical structure. Understanding the spatial relationships helps you predict character movements:

• The Entrance leads directly into the Living Room
• The Dining Room and Kitchen are connected — food moves between them
• The Study and Billiard Room are off the main hallway — for private activities
• The Chapel is a separate wing — for spiritual and supernatural scenes
• Quail Lane is exterior — for conversations away from other guests
• Upper bedrooms are accessed via staircase — for intimate or confrontational scenes
• The Attic is above the upper floor — for the most dramatic revelations

When a character leaves one room, think about where they would logically go next. A character leaving the Dining Room might go to the Kitchen or the Living Room. A character seeking privacy might go to the Study or Quail Lane. This spatial reasoning helps you predict which codes to try.

The Full House Achievement Roadmap

To earn Full House efficiently, follow this discovery order:

1. Enter chronological Part 1 codes (01 through 06) — automatically discovers EN, LI, QU, ST, KI, DI
2. Enter codes 07-BI-5-10 and 08-CH-4-11 — discovers BI and CH
3. Continue with mid-game codes 12-ED through 21-OS — discovers all bedrooms
4. Enter 13-AT-1-4 — discovers the Attic
5. Enter 25-WI-9-11 — discovers Wintercote

If you follow this order, you should have all 16 locations labeled well before the end of your playthrough. The most common roadblock is missing Wintercote — if you have 15 of 16 locations, WI is almost certainly the one you are missing.

Common Location Discovery Mistakes

Forgetting to Label

Discovering a location is not the same as labeling it. When you enter a code that produces a valid scene, the game registers the location, but you must formally assign the two-letter code to the room. If you enter a valid code but do not label the location, you cannot use that location code in future codes.

Always label locations immediately after discovering them. Do not wait until later — the moment you see a new room name in a scene, assign its code.

Ignoring Exterior Locations

Many players assume all 16 locations are indoor rooms and overlook Wintercote. Remember that Galley House includes exterior spaces that have their own location codes.

Not Trying Character-Matched Rooms

If you have identified Person 5 as Edmund "Eddie" Galley, try entering codes with the ED location and character 5. The game's design means that each bedroom is associated with a specific character, and using the character number with their room code is a reliable way to discover scenes.

Missing the Attic

The Attic is easy to miss because it does not feel like a regular room. Search for "attic" in the keyword tool and request hints about the body discovery to find this critical location.
