from poeppelkiste.de:

One player uses magnetic force & an ornery witches broom to move his magic crystals across the board and into the cauldron. At the same time, another player rolls dice as the Guardian of Time in order to stop the player turn. Whoever gets four crystals in first wins the game.

from HABA website:
All the witches have gathered for the duel with the jinxed broom Mumbo Jumbo. Each one tries to tame the flying broom and make it sweep their magic gems into the cauldron. However, only the one who has a magic touch with the witch's magnetic power will be the first to be able to sweep his magic gems into the cauldron.
