This expansion to the The Duke core game, adds a little literary flair, while also changing the winning conditions of the game. However, with this expansion the actual Duke tiles are replaced by the opposing characters of Robin Hood and Prince John. It introduces seven characters taken from the Robin Hood literary universe.

This expansion does make some modifications to the starting tile set, including the creation of asymmetrical opposing forces. It also provides one alternate playing scenario for the game using the expansion tiles which changes the winning conditions of the game:
1. To win the Prince John player must capture Robin Hood.
2. To win the Robin Hood player must capture Prince John, The Sheriff, and Sir Guy, assuming all of them are in play. Otherwise the Robin Hood player must capture any and all of those that are in play, which may end up only being starting tile of Price John.
