Sentence construction is the main game mechanic of Soap. Characters can never be killed unless their secret is discovered. If a player uses a sentence in the game that hints at his secret, he gains five tokens for his daring. Once a secret is revealed, however, that character can be killed off by the other players if they choose to do so. Tokens can be used to start, join, or continue a scene.
All players start with two tokens.
A scene can be started by paying a token. Your character can join a scene already in progress but it can be opposed by the creator of the scene by starting a bidding war of tokens. Continuing a scene means that your character is already in a scene and that he can use either a positive or negative sentence on anyone in the scene with him or in the game. Positive sentences are used to either hint at your secret or to gain plot tokens. Negative sentences are used to annoy or thwart other players plans.
