The Missing Blueprints Card Set
Embedded Files
The Missing Blueprints Card Set adds physical card play to the Winchester Mystery House investigation.
Collect blueprint fragments, route cards, strange architectural clues, and key evidence as the house begins to rearrange itself around the case. Scan or type visible card codes into Hauntline to update the Journal, Inventory Ring, active route events, finale state, and Safe Return.
This set is designed for The Missing Blueprints expansion and works alongside the universal Hauntline Card System.
How The Cards Work
How The Cards Work
Open Hauntline Horror Location Engine, start The Missing Blueprints, then scan or type these card codes during play.
Cards can add blueprint clues to your Journal, place tools or keys in your Inventory Ring, trigger route changes, reveal hidden rooms, start the finale, or activate Safe Return.
Journal / Case File — store blueprint fragments, house records, clues, and known rooms.
Inventory Ring — carry usable items, keys, tools, and marked plans.
Active Event Area — keep route shifts, false doors, and danger cards visible until resolved.
Finale / Safety — hold The Final Room and Safe Return until the game calls for them.
The Missing Blueprints Card Set
The Missing Blueprints Card Set
The Missing Blueprints cards are divided into four physical play areas: Journal / Case File, Inventory Ring, Active Event Area, and Finale / Safety.
When you find a blueprint clue, place the card in your Journal. When you collect a usable item or key, carry it in your Inventory Ring. When the house changes route, keep the route or danger card active until resolved. When a card is used, spent, cleared, or discarded, update both the physical card pile and the GPT inventory.

Card Types
Card Types
The Raven Key card set uses several card types to control physical and digital play.
Entry Cards — start or anchor the investigation.
Clue Cards — store evidence inside the Journal / Case File.
Item Cards — enter the Inventory Ring and can be used during scenes.
Route Cards — open, change, or test movement through the Tower.
Danger Cards — stay active until the threat is resolved.
Finale Cards — trigger the final confrontation.
Safe Cards — pause the game or return the player to a safe point.
Physical Inventory Ring
Physical Inventory Ring
The Inventory Ring is the player’s real-world card inventory. It can be a binder ring, pouch, card sleeve, journal pocket, or case-file stack.
When the GPT says an item is found, the player takes the matching card. When the item is used, spent, traded, or consumed, the player discards or archives the card. This keeps the physical table state and the GPT game state aligned.
