Design the best Animal Sanctuary while playing 5 rounds. Each round, you'll have to draw 3 cards, place one, and pass along the others (simple drafting phase). Each card is composed of 4 biomes, each one of them containing an animal. When you place a card, you have to cover AT LEAST one biome. Thus, the whole Sanctuary must fit in a 6 by 6.
Each game will have a different pool of various objectives. Each round will count only some of the objectives chosen for the game. So you'll have to modify your sanctuary during all the game so as to score points according to the ongoing objectives. At the end of the 5 rounds, the player who earned the more points becomes the winner!
