Overview
Coup is a social deduction card game designed by Rikki Tahta and published in 2012 by Indie Boards & Cards and La Mame Games. Players are given two cards and attempt to eliminate the other players by lying and calling their bluffs until only one player remains.
Gameplay
Each player has two face-down character cards, with the remaining cards being placed in a "Court Deck" in the centre of the play area. Players take turns performing actions, while the other players have the opportunity to challenge or enact a counteraction.
Some actions and counteractions require a player to claim to have a specific character card (which they can do regardless of whether or not they have it). Such claims can be challenged by anyone in the game, regardless of whether they are directly involved in the action. If a player is challenged, they must prove they had the played character card by revealing it from their face-down cards. If they can not or do not want to prove it, they lose the challenge, but if they can, the challenger loses. Whoever loses the challenge immediately loses one of their character cards. When a player loses both their character cards, that player is eliminated. The winner is the remaining player after all others have been eliminated.
