Am I correctly understanding that the 1st time you discover an animal, you get both points and card, while further discoveries of a duplicate of that animal result in just points? And then, at game-end, you get the points again for the cards (along with any combo points)?
Thanks for clarifying that the intent is to score double for animals that are new to you, and less (single points) for duplicates.
Yes. The first time you get the card, which at the end of the game gives you the points on it along with any bonus point for combinations.
The second time you just get point chips that count for points at the end of the game, but doesn't allow for combo bonus points.
