In O Vale dos Monstros ("Monsters' Valley"), players compete to see which monster is the most terrifying! Players can choose between vampires, werewolves, ghosts, witches, skeletons and mummies, each with different skills but all with the same purpose: Scaring visitors (children, men and women) at the camping area and taking control of their tents. Each turn, players perform three actions, such as moving up to three spaces on the hexagonal board, scaring a visitor, capturing the visitor and transforming it into a monster, taking control of a tent, and even attacking the other monsters! Players receive points for controlling tents, scaring visitors and having a large number of monsters. The player with the most points wins. O Vale dos Monstros includes two expert variants as well as different camping set-ups.
