This game takes its name from the story of King Arthur, famous for his round table whose memory this board evokes. The idea of playing Chess on a round board is nothing new. Such a game existed in the days of the Byzantine Empire, and numerous adaptations of it have appeared since.

Almost by accident, I found that an odd number of radial files on a round board had the effect of unbinding the Bishop (a fascination of mine), allowing it to access every cell on the board, unlike its FIDE counterpart, which can access cells of one colour only. A player's two bishops may therefore support each other. One file, called the International Date Line, is coloured differently from the others. A Bishop passing through the International Date Line moves from cells of one colour to the other.

The rules, which are the same as in traditional chess except for a few minor tweaks, are in the "Readme" file. There is also a "Diagrams" folder, with images in GIF-format illustrating the moves of each piece.
