Urknall: Supernova

Translated from the German text on the publisher's website: The expansion contains a rulebook and a single game piece. The Supernova adds extra uncertainty to the game. If a star becomes a supernova the possession ratios are lost and it is played again. Counting the supernova: at end of the game every possession marker gets you as many points as elements of the same color are present. It is not about possession ratio. Every possession marker counts.
