Cockroach Poker

Cockroach Poker is a reverse set collection game that has nothing to do with poker – except that the game is all about bluffing, but with cards that show cockroaches, rats, and stink bugs instead of queens, 10s, and aces. The goal of the game is to force another player to collect four of any one type of critter.

The deck includes 64 cards, with eight copies of eight types of critters. To set up the game, shuffle the deck and deal the cards out to players.

On a turn, a player takes one card from their hand, lays it face down on the table, slides it to a player of their choice, and declares a type of critter, e.g., "Stink bug". The player receiving the card can either:

• Accept the card and say either "true" or "false", then reveal the card. If this player is wrong in their claim, they keep the card face up in front of them; if they are right, the player who gave them the card places it face up before themselves.
• Peek at the card, then pass it face down to another player, either saying the original type of critter or a new type. This new player again has the choice of accepting the card or passing it, unless the card has already been seen by all other players, in which case the player must take the first option.

The game ends when a player has no cards to pass on their turn or when a player has four cards of the same critter in front of them. In either case, this player loses, and everyone else wins.
