Player One starts the game by asking Player Two: "Truth or Dare?" If Player Two chooses "Truth," then Player One poses a question, usually embarrassing, and Player Two must answer. If Player Two chooses "Dare," then Player One poses a task, also usually embarrassing, which Player Two must perform. After answering the question or performing the dare, Player Two takes Player One's place, asks "Truth or Dare?" of another player, and the game proceeds as before.
If the queried player fails to complete their dare or answer their question, they are faced with an even more challenging dare or question. A player cannot choose truth three times in a row or they have to do two extra dares. Some even play with cue cards, which have a labelled truth/dare on it.
A variant of the game entails a player to pose a question to another player, who has the option to answer the question truthfully or decline, in which case they must perform a dare also posed by the questioner and typically of an embarrassing nature.
Questions and or dares cannot be asked twice in a row or in a consequtive order.
Players can also ask each other questions through methods of Spin the Bottle; where the bottle lands, a player is questioned.
