Sunset Sky expands Snowbirds with 18 new Map cards, introducing 4 new location effects, offering a whole new landscape for your flock to explore. In addition to new bonuses and hazards, it also provides a new deck of Actions and rules to adapt the solitaire experience into a 2-player game. With a second flock in the sky, you can compete to see who can better manage the long journey south with their limited actions and resources. Players willing to take greater risks can gain an edge in an already tense race for survival. Can you bring your birds home? This expansion requires the base game to play.
