Players boast about the elusive creatures they claim to have seen in the mountains. But can you always believe their stories?
Every player gets five cards, showing one of five animals with quantities of 1, 2 or 3. The starting player plays a card face down on the table, making a claim such as "I have seen one Yak", then draws a new card. Next player adds to that stack, raising the claim, either by raising the number or the size of the animal. The cards in the stack represent the animals which have actually been around. Play continues in clockwise order until a player calls a bluff and flips open the stack. If it doesn't contain at least as many animals of the last kind as were announced, the bluffing player takes the stack as a penalty, if it does, the caller takes them.
The game is a simplified reimplementation of Bluff im Zoo.
