Essen 2013 Bluff Im Zoo
Similar to Shadows over Camelot the card game or Perudo.
You play a card face down and claim there are 1 of a certain animal played so far.
The next player plays a card and must declare a higher number but can change the animal.
This continues until one person calls the previous call wrong.
The cards played are checked. If there are equal to or more than the number of the cakled animals they are correct and the person that calls them a liar takes the card. Otherwise the incorrect player takes them.
Fewest cards at the end wins.
Very fun, very cute.
