From the rules: The object of the games is to lose your marbles. Each player is given a set of marbles and a set of idiot cards. Each round of play a Fnerd card is turned over. Each player plays an idiot card, and the winner will lose the number of marbles marked on the Fnerd card. The player of the worst idiot card becomes the Psychiatrist, moves the token around the board, and gains the number of marbles shown on the space where it lands. Additional bonuses and penalties are paid out as instructed on the idiot cards, and a fresh round takes place. Play continues until one player has lost all his marbles - the winner!
