Description from the publisher:
In Rumpelstiltskin, you and a friend take the roles of fey folk who have decided to engage in a name guessing contest. You must use your magical mischief to learn your opponent's secret name while protecting your own!
Players alternate taking turns. To take a turn, you play one card from your hand, perform its actions, then put it in your discard pile. Some cards let you try to win the game by guessing your opponent's secret name, i.e., the card on the bottom of their deck). Your opponent may use a reaction, but then must tell you if you guessed right or wrong. If you guessed correctly, you win! If the card you guessed is not on the bottom of your opponent's deck, play continues.
