The King’s Keys deck takes a new look at playing cards. While standard decks are 4x13 (4 suits and 13 ranks), the King’s Keys deck uses a 4x4x4 logic. Each card in the 64 card deck has a Number (1, 2, 3, or 4), an Item (Key, Axe, Shield or Coin) and a Kingdom Color (Yellow Sun, Red Mountains, Green Forest or Blue Ocean). The deck plays a variety of games for players at all skill levels. Some rules are included with the deck but most are on the website. Players are also encouraged to try inventing new games of their own.
