Every spring, millions of monarch butterflies leave Mexico to spread out across eastern North America. Every fall, millions fly back to Mexico. However, no single butterfly ever makes the round trip. Mariposas is a game of movement and set collection that lets players be part of this amazing journey. Mariposas is played in three seasons. In general, your butterflies will try to head north in spring, spread out in summer, and return south in the fall. At the end of each season, there is a scoring round. At the end of fall, the player with the most victory points has the most successful family of butterflies and wins the game.
