Cockroach Poker Royal is a reverse set collection game that has nothing to do with poker except that the game is all about bluffing. The deck shows cockroaches, stink bugs, rats with crowns..... The goal of the game is to force another player to collect 4 of any one type of critter.
The game ends when a player has no cards to pass on his turn or when a player has four cards of the same critter on the table in front of him. In either case, this player loses and everyone else wins!
