Gnostica is an abstract territory based war game. Tarot cards make up the often-changing board, and players use Icehouse Pieces to represent minions that control those territories. Every tarot card has a power, and when a player has one of his pieces on a territory, he or she may use the power of that territory through that piece. Players also have a hand of tarot cards which allow them to use those powers through any of their pieces. Territories are worth points when occupied, and the game ends when one player challenges the other players and has 9 points on his or her following turn.Gnostica is a redevelopment of Zarcana. - BoardGameGeek
