From the box:
We go hunting at the beginning of all eras. But it’s necessary to be very clever. To be able to hunt the greater amount and variety of animals is privilege of few. But take care! You have saboteurs around you. Be careful not to wake up envies it in the other hunters, because if they realize you have more animals than them, they will make them disappear.
Each turn, players must choose between a set of animals displayed in the table and put them in front of themselves. They must be very careful not to pick too many animals of the same kind, because the player that has the most animals of a kind loses all of them at the end of the game. Then players count their points. The game ends after several rounds when a player has reached 40 points.
