Pyramid (Battlestar Galactica) is a card game based on the 1970s television series 'Battlestar Galactica'. It was depicted as leisure activity for the characters in the television show. Later on, rules and decks of pyramid playing cards were made available commercially to fans of the show. Both are currently out of print. The game uses a 55 count deck of hexagonal cards separated into three kinds of suits and three ranks as well as a 'capstone' card which is used as a wild card. The game is played very similarly to poker. Players are dealt hands and place bets based on how strong their hand is. There is a discard between bets and players reveal their hands to determine the winner of that round.Winning hands are determined by a number of factors including suit, rank and matching sets. There are approximately fourteen different hand combinations possible in the game. There is no 'end' to the game, players merely quit at their leisure.Complete rules can be found at: http://en.wikipedia.org/wiki/Pyramid_%28card_game%29 - BoardGameGeek
