OCHO VAMPIROS is a strategic, double-sided card game based on the urban myth of border-crossing Mexican vampires (Vampiros). One side of each card represents a Street or City Park the opposite side of each card represents a Room -- Bedroom, Art Gallery or Gymnasium are examples. This represents players movement along dark city streets and into and out of unlocked buildings. Players DO NOT conceal their cards, and points are accumulated by playing 'VAMPIRO' (vampire) cards atop the cards on an 'In-Play' pile. Each time any player places a 'DOOR' card on the In-Play Pile, all cards are 'flipped,' revealing the cards opposite side. Play is fast-paced. A good memory will benefit play. OCHO VAMPIROS is best as a strategy game when played with four or six players in teams of two, working in conjunction to accumulate points. Cards are art-quality and sold online and through art galleries Only one deck is required for play however, experts add additional decks to increase strategy options. - BoardGameGeek
