As in its parent game Kakerlakenpoker, Kakerlakenpoker Royal has nothing to do with poker – except that the game is all about bluffing, but with cards showing cockroaches, rats and stink bugs instead of queens, 10s and aces. To set up the game, shuffle the deck and deal the cards out to players. On a turn, a player takes one card from his hand, lays it face down on the table, slides it to a player of his choice, and declares a type of critter, e.g., "Stink bug". The player receiving the card either:
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.
To this, Kakerlakenpoker Royal adds new rules and new nasty "royal" critters to create more options for players during the game.
