Whoever leads an expedition to the destination of a such mission takes the corresponding card and lays it in front of him. You get one additional point at the end of the game. Subsequent the public research mission stock is replenished again to six. The card that is uncovered is valid for each case, no matter how far it is from the starting point and even if an expedition has already traveled to this place. The expeditions are neutral.
Plays proceeds in clockwise order.
Per game turn, one may place one arrow. The arrows must always be put on a position between two points. The oldest player starts. He takes one arrow of an any color and puts it by the starting point on one of the six positions. But the arrowhead always points from the origin to the next station.
