Poisons is a bluff-based card game in which players have to carefully weight their risks to earn points. Each turn, players secretly add a card from their hand to each opponent's drink: an innocuous liquid or a deadly poison. When everyone has their cup filled, each player decides whether they will drink the contents of their cup.
Those who don't dare to sip the mixture gain only a minimal amount of points. Those who drink their cup score the number of points revealed at the beginning of their turn, but beware if there's a single dose of poison in the glass, they get nothing!
After four rounds of libations, the player with the most points win. Advanced rules add new kinds of drinks with special effects, for an even deeper mind game between the players.
