Casus Kim? - Köstebek

At the beginning of the game, the number of players and the number of spies are chosen. Then, names are written down and the game begins. Each player, when it's their turn, takes the phone and, without revealing their identity, memorizes a word and passes it to the next player. The word shown to the spy is different but similar to the words shown to the others. The spy tries to blend in without revealing their identity. At the end of the game, if the spy is found, it's marked "found," otherwise, it's marked "not found," and the scoring continues.
