Our full review: Betrayal at House on the Hill Review

Note: These simplified rules help you get started quickly. Read the full rulebook before your first play — there are 50 different Haunts, each with unique objectives.

The Big Picture

Betrayal has two phases:

Phase 1 — Exploration: Everyone cooperates, exploring the house tile by tile, collecting items, and surviving Event and Omen cards.

Phase 2 — The Haunt: When triggered, the game reveals which player (if any) is the Traitor. Traitor and Survivors read separate rulebooks with secret, usually opposing objectives.

Setup

1
Each player chooses a character card (each has two sides). Place four starting room tiles: the Upper Landing, Basement Landing, and Main Floor Entrance.
2
Shuffle the Event, Omen, and Item decks and place them face-down. Take out all the dice.
3
Set your character's stat markers (Speed, Might, Sanity, Knowledge) on the starting values shown on your card. Track these on paper or use the companion app (search "Betrayal Character Stats").
4
The player with the next upcoming birthday goes first.

Exploration Phase

1
Move up to as many rooms as your Speed stat allows. You can move through any open doorway.
2
When you enter an unexplored doorway, draw a room tile. Place it on the matching floor (rooms are labelled Upper, Middle, or Basement). If the tile doesn't fit the current floor, set it aside and keep drawing.
3
If the new room has a symbol, draw the matching card (Event, Item, or Omen) and follow its instructions.
4
After drawing an Omen card, make a Haunt Roll: roll 6 dice (faces 0–2). If your result is lower than the total number of Omen cards drawn so far, the Haunt begins.

If your stat reaches the skull-and-crossbones, you die and are out of the game.

Starting the Haunt

When the Haunt is triggered:

1
Open the Traitor's Tome and cross-reference the room where the Haunt started with the Omen that triggered it. This tells you who (if anyone) is the Traitor.
2
The Traitor leaves the room and reads their secret objective in the Traitor's Tome. Everyone else reads their objective together in the Secrets of Survival book.
3
Objectives are usually directly opposed — the Traitor wins if the Survivors fail, and vice versa.
4
Some Haunts introduce monsters. These are moved by the Traitor each round using the rules in their section of the Traitor's Tome.

Tips for New Players

  • Track stats on paper — the card markers slip easily.
  • The Haunt Rolls start low-risk but become likely after the fourth or fifth Omen card.
  • Each of the 50 Haunts has completely different objectives. Read yours carefully before the battle phase begins.
Is there always a Traitor?

Not always. Some Haunts have no Traitor — the Survivors face a monster or scenario without anyone going evil.

Can dead players still participate?

No — if your stat reaches the skull, you're out. Some players use dead characters to observe and offer neutral commentary.

Can the Traitor lie to the group before the Haunt?

Yes — the Haunt assignment is secret until the roll, but there's nothing stopping you from being a suspicious character during exploration.
