In Perfect Shot, you'll have to take pictures of animals to win the most victory points. On your turn, you take either take an Album card or you can place a Landscape punched card from your hand onto the previous Landscape card in the game shoe. If any animal appears partially or entirely in the camera lenses of your Landscape card, you can take the corresponding Animal Photo tile(s) and put them in one of your photo Albums while respecting the constraints of the Albums- only snow animals, for example. A complete Album allows you to earn even more victory points so you have to organize your photos well.
And if an animal fits completely in your lense, it's a Perfect Shot and one more step to victory! As for the Yeti, it is so fierce, wild and mysterious that you can only see half of it in the photos you take. It will take two different halves to prove to the world its existence... and gain more and more victory points.
