Betrayal at House on the Hill – The Original Hidden Traitor Horror Game
Explore a haunted mansion tile by tile — until one player becomes the traitor. 50 unique haunts, endless replayability, and the original that inspired Betrayal at Baldur's Gate.
📋 Game Details
Betrayal at House on the Hill is the game that defined the hidden traitor horror genre. First published in 2004 and now in its 3rd edition, it places 3 to 6 players inside a haunted mansion that reveals itself room by room as they explore — until one fateful moment when the haunt triggers and everything changes.
One player becomes the traitor. The Traitor's Tome reveals their secret goal. The Survival Guide tells the remaining heroes what they must do to stop them. And no two sessions ever tell the same story — 50 unique haunts ensure every game is a different nightmare.
Players who discover Betrayal at House on the Hill consistently describe the haunt reveal as one of the most memorable moments in all of board gaming — the shift from cooperative exploration to sudden betrayal creates a tension that nothing else quite replicates.
How to Play — Watch First
What Is Betrayal at House on the Hill?
Betrayal at House on the Hill is a semi-cooperative exploration and hidden traitor game for 3 to 6 players. Players choose from a roster of unique characters — each with different stat profiles — and explore the mansion by drawing and placing room tiles. Every new room is a discovery: some contain items, some trigger events, some reveal omens.
Each omen drawn triggers a haunt roll. When the haunt triggers, one player consults the Traitor's Tome privately — learning their new objective and special powers. The other players consult the Survival Guide — learning what they must accomplish to win. Then the race begins.
The Two Phases
Exploration
Explore the mansion cooperatively — draw tiles, collect items, discover omens. Build the house together before everything goes wrong.
The Haunt
One hero becomes the traitor with a secret goal. 50 unique haunts create 50 completely different endgame scenarios.
50 Haunts
From zombie outbreaks to demonic rituals — each haunt creates a unique story the group will talk about long after.
Modular Mansion
Rooms are placed as players explore — the mansion layout is different every session.
What's New in 3rd Edition?
The 3rd Edition updates the classic with improved components, cleaner rules, and revised haunts that address some of the balance issues found in earlier editions. The character boards have been updated, several haunts have been rewritten for clarity, and the overall production quality is the best the game has ever seen.
If you already own a previous edition, the 3rd Edition is a worthwhile upgrade. If you're new to the game, the 3rd Edition is the definitive version to buy.
