The 128 cards – 120 vegetable cards in the four types and eight "taboo" vegetable cards, two of each type that bear cockroaches – are shuffled and divided among the players. On a turn, a player plays the top card from his deck onto the central pile of cards, naming the vegetable as he plays it, e.g., "Pepper!" – except in the following situations:
• If his vegetable matches the previously played vegetable, the player must lie.
• If his vegetable matches the claim made by the previous player (perhaps because that player lied), then the player must lie.
• If he plays a taboo card, he shouts "Cockroach!" and the next player starts a new pile next to the first one so that the taboo card remains visible.
• If his vegetable matches a visible taboo card, he must lie.
Make a mistake or stumble or hesitate too long, and a player must pick up all cards played to that point in the game. The first player to run out of cards wins!
