The overall tone of the game can differ depending on how "hardcore" the players want the questions or dares to be. Some games are denoted as "friendly" where sexual acts, nudity or over-personal questions are avoided (the best way to play if there are couples). There can also be supplemental rules as to how many truths a player can take before they must take a dare (often no more than 2 truths in a row). In some cases the game is modified to be a drinking game, where a person has to drink if they pass when chosen.
