You have an ark- and you want to take as many animals on board as you can. Unfortunately- a guy called Noah claims all animal pairs for himself - and he`s obtained an anti-pairing law! Therefore- any animal for which a player has exactly two on board at the end of the game must be handed off. However- you can circumvent the law if you manage to gather three- four- or even five animals of a species. These are considered a herd and are not only permitted- but are more valuable. Sounds easy- right? Wrong! To form a herd- there`s no way around getting a pair first!
