Keystone - North America

Keystone North America is a card placement game inspired by a passion for wildlife and its conservation.
1 to 4 players take on the role of biologists, working to build an interconnected ecosystem through the placement of different species. Those that are better connected will score more and the biologist who gets the most points will be the winner.
Keystone: North America takes place over a series of rounds in which each player takes a turn to play. Your purpose is to place cards on your player board to form ecosystems and complete your secret objective. Simply put, an ecosystem is a sequence of two or more cards that share a habitat, forming a straight line in consecutive numerical order.
Ecosystems can be improved with Research tokens and with Key species, identified by the Key Species icon. Your Secret Objective is completed by matching groups of cards from your player board with the patterns on your Secret Objective card.
