Players are witches trying to make their potion. Each witch is associated to a secret color with match a cauldron. In turn each witch rolls a colored die and must put a face down mushroom in the cauldron indicated by the die using a wooden spoon. Other players try to guess whether she is putting a right color mushroom or a wrong one.
Guessing right stops the witch and reduce the number of available mushrooms of the guesser, accusing a innocent witch increases the available mushrooms of the guesser.
The game ends when a witch is left without mushrooms and she gets one extra point for herself and subtracts one point from a chosen cauldron. For each cauldron a right color mushroom scores one point to the secret owner and a wrong one subtracts one point.
