Hauntline is an interactive horror game engine built for remote play, live locations, and host-led investigations.
Players explore haunted scenarios through choices, maps, journals, inventory, clue reveals, and atmospheric images. Hosts can create custom games using real-world locations, uploaded maps, physical props, and printable event cards.
You can play from home using premade haunted locations, or use Hauntline as a live game companion at a safe, permitted location.
Start with one of five short playable haunted investigations. Each one is designed as a quick Hauntline demo with a map, clues, inventory, entity encounter, and multiple ending paths.
The ravens are restless, and one black feather has appeared where no raven should have been. Search the Tower for the Raven Key before the prison echo writes your name into the stone.
The first page is blank until you step inside. Then your name appears in a hand that does not belong to you. Find the Warden’s Ledger before the prison assigns you a cell.
The mansion keeps asking for one more door. Recover the missing blueprints and decide whether to destroy the false room or step through the Door to Nowhere.
Beneath South Bridge, the old vaults remember every footstep. Recover the missing Brass Seal before the under-city echo learns your route.
The forest repeats the path of the vanished shepherd. Follow the tally marks, avoid the third blue light, and return the Birch Charm before the ring closes.
Start the Hauntline GPT and choose how you want to play.
Play a premade haunted location, upload your own map, scan a Hauntline card, or start a hosted live game.
Choose how often Hauntline creates visual moments: Off, Low, Medium, High, or Cinematic.
Use choices, maps, inventory, journal entries, photo reveals, and entity encounters to progress through the game.
Uncover the truth, survive the finale, or unlock a secret ending.
Hauntline supports physical clue cards and event codes. Cards can be printed, carried, hidden by a host, or used as part of a live location game.
Each card includes a visible event code. Players can upload a photo of the card into Hauntline, and the GPT reads the code to unlock a clue, item, zone, mission update, or finale event.
The QR code points to this Hauntline page so players and curious passers-by can learn how to play.
Upload a hand-drawn map, floor plan, aerial screenshot, trail map, venue layout, or rough sketch. Hauntline can turn it into a playable horror map with zones, safe points, off-limit areas, objectives, clues, and item markers.
Players can also upload safe, permitted photos during play. Hauntline can use those photos to reveal hidden symbols, ghostly figures, item hints, map changes, or puzzle clues.
