Sky Towers is a family friendly card game, in which you are building towers of cards. When your tower adds up to 21, you set it aside and keep building. Most cards have an ability or limitation. The challenge is that you cannot play a card that matches the top card in the other players' tower. Points, represented by yellow kites, are counted at the end of the game. Most points wins.
