Overview

Poison is a card game where players take turns playing Potion Cards into cauldrons, trying to avoid pushing the total value in any cauldron over 13. If you cause a cauldron to exceed 13, you must collect all previous cards from it. At the end of the round, each collected card is worth negative points, but collecting the most of a single color grants immunity to that color. Poison Cards are wild and worth double penalty points.

Components

Setup

  1. Place the 3 cauldron boards in the center of the table.
  2. Choose a dealer. The dealer shuffles and deals all 50 cards one at a time to all players. Some players may receive one more card than others.
  3. With exactly 3 players, deal 4 hands and remove the extra hand from the game unseen.
  4. The dealer rotates to the left each round.

Turn Structure

The player to the left of the dealer goes first. Play proceeds clockwise. On your turn, you must play exactly one card face-up into a cauldron.

Scoring / Victory Conditions

At the end of a round (when all cards have been played):

  1. Each player examines their collected cards.
  2. For each of the 3 Potion Card colors, the player who collected the most cards of that color discards all cards of that color (immunity). In case of a tie for most, no one gets immunity for that color.
  3. Each remaining Potion Card in your collection scores 1 penalty point.
  4. Each Poison Card in your collection scores 2 penalty points.

Play multiple rounds. The player with the fewest total penalty points after the agreed number of rounds wins.
