Köstebek: Party Game

Trust no one. Who is the mole at your table? Pass one phone, peek at your card, give your clue and catch the bluff. Four games for 3–15 players, fully offline.

One phone. One table. One player whose card does not fit.

Köstebek is a face-to-face party game for 3–15 players. Pass the phone, reveal your card in private, take turns giving clues, then debate and vote. No extra devices, accounts or internet connection are needed.

FOUR DIFFERENT WAYS TO BLUFF

SECRET WORD Most players see the same word. The mole sees only a broad hint that does not reveal the answer and must improvise a convincing clue without giving themselves away.

ODD WORD Everyone sees a word, but one player receives a closely related alternative. By default, even the mole does not know their card is different.

MIMIC Act out the prompt without speaking or making a sound. One player receives a different but similar action. Supports 3–12 players.

BLUFF Answer your question aloud in one sentence. One player has a different question, and the two prompts are designed to produce deceptively similar answers.
