One Drunk Night... is a dark humor story-building game where players craft a drunken adventure together. The result is unpredictable and frequently crude with potential catastrophic moral repercussions on your psyche. In this game, the Storyteller begins by choosing one of two "Beginning..." cards to start the adventure. The other players choose one "...Middle..." or "...End" cards from their hands to continue the story and play them face down. The submitted cards are shuffled and read aloud by the Storyteller. The Storyteller then chooses the card he/she wants to use to continue the story. The player who submitted the chosen card receives one point if a "...Middle..." card was selected and two points for an "...End" card. Play continues with the same Storyteller until an "...End" card is selected, adding to the last selected card each time to grow the adventure. After an "...End" card is chosen the adventure is read aloud and play rotates to the left. Stories can go as long as the players decide allowing for much more replayability and variety than play X match Y mechanic found in other party card games. Players decide the ending conditions and the player with the most points is the winner if score is being kept.
