If you don’t get the title… Charlemagne was king of the Franks. Just a little bit of sophomoric humor. That being said, you do not need to be a history buff or even need access to Wikipedia to appreciate this game. Reiner Knizia’s Knights of Charlemagne (yes, this is the full name of the App) is a game based off of a current card/strategy game. While the translation of card games onto the iDevice platform is nothing new, Knights of Charlemagne’s faithful transition onto a digital platform is of some note. It was ranked the 9th most popular card game of 2006.
