Castle Builders is the first game in the Game-o-gram series. All games in the Game-o-gram series should fit on a postcard and should preferably contain everything needed to play. Castle Builders is a quick two player game where the players are building towers in a castle. The king, for whom the castle is being built, will reward the players when the castle is finished depending on their building skills. The basic idea of the game is that it should be cheap enough for everyone to buy, easy enough for everyone to play and interesting enough to play over again.
