In a game of Little Secret, each player has a mission card with several passwords.
The Grand Master chooses the number associated with a word with which the game will be played.
One by one, each player gives a word/adjective qualifying the chosen password, and then votes for the person they feel has a different word.
Players don't know which side they're on, but should try to guess as the game progresses. For games of 5 players or more, a "Journalist" is also present in the game. The Journalist has no password, and must guess the majority word, that of the Disciples. The Infiltrators, on the other hand, have a slightly different word from the Disciples.
Power cards completely change the course of the game, giving each player a different characteristic.
