What is it?

BS (also known as Cheat, Bluff, or I Doubt It) is a card game that tests players' ability to deceive and detect lies. The game is played with a standard deck of 52 cards and involves players taking turns placing cards face down while declaring their rank, typically in ascending order. However, players can lie about the cards they are playing. Other players have the option to challenge a play by calling "BS," forcing the accused player to reveal their cards. If the challenge is correct and the player was lying, they must take the entire discard pile; if the challenge is incorrect, the challenger takes the pile instead. The goal of the game is to get rid of all one's cards first. BS combines strategy, deception, and social deduction, making it an entertaining and unpredictable game.
