Betrayal At House On The Hill is a game played on Board AF.
The game begins with the 'Exploration Phase', where players move through several rooms, finding items, events or omens. When an omen card is found, the player must roll 6 dice and the roll must be higher than the number of omen cards in play for the exploration phase to continue. If the player rolls less than the number of omen cards in play, the 'Haunt Phase' begins. This phase differs each game and is based on the omen and room the omen was found in, with these items determining which player would be the traitor. The traitor and the remaining players read their specific goals for the haunt they are playing, and attempt to complete their goal. Whichever side (Traitor or Players) completes their goal first, wins.
