from translation:Harun was originally meant as an 'introductory game' to Corona. This time there are seven heavenly bodies, which move on an orbit of 12 fields. Also 4 multicolored fixed stars are distributed on the orbit. The object of the game is it to move the heavenly bodies onto the fields with the fixed stars: But there are points. A new round begins each player can call aloud the score he believes achievable. Whoever comes up with the highest correct estimate wins. If the player achieves his estimate, he is recompensed plentifully but receives a punishment if it he does not achieve his estimate... - BoardGameGeek
