When players draw a tile, they select a facedown tile and place it on one of the available spaces on the trucks (usually the number of trucks equals the number of players). Placement of the tile is critical in order to make or not make sets enticing. Players can also spend money to manipulate the location of their animal collection, acquire animals from other players, discard animals, or expand their zoo. Lastly, players may elect to take a truck. The truck is placed in front of the player who unloads the truck into their zoo. Only like animals can be placed in the same paddock. Also, food stands are placed on the empty spaces around the perimeter of the zoo. Any excess tiles are placed in the barn and may yield negative points at the end of the game. If there is a male and female in the same paddock, love is in the air. A baby is born and also placed into the paddock with the parents — unless the player planned poorly forcing the baby into the barn. Once a player has taken a truck, they are out for the remainder of the round. Once all players have taken a truck, then a new round commences and the trucks are returned ready for filling. The game continues until the 16th to the last tile is chosen. Once that tile is taken, the game will end once all of the players have taken a truck. Points are rewarded for full and almost full paddocks (missing one animal). Different market stands award additional points and help with under-filled paddocks. Negative points are applied for animals and market stands left in the barn.
