A four man chess game with the legends of Camelot added for a different adventure to each game played.
Each player represents a suit of cards, the heart player must have hearts in his hand to play a piece. An ace will allow you to move one piece one space, therefore you must have a 3 or above to move a knight.
Add to this magic cards that can allow you to do anything from a regular piece movement to arbitrarily removing an opponents piece from the game. All this and a roaming giant and dragon... Not your normal game of chess anymore.
