Division: Throne Room is a strategic card and dice game for 1 or 2 players. You'll recognise the King and his courtiers from chess. But this game is not fought on the battlefield. This is an internal fight for the throne.
In the 2-Player game, you and your rival are competing to bribe, blackmail and bully the courtiers into a configuration that'll aide your own efforts to seize the throne. Completing all of your Palace Cards before your rival means you have successfully ousted the King and taken the throne for yourself.
In the 1-Player game, you are playing against the Silent Hand. You won't see or hear from this shadowy syndicate, but they'll always be in the background, manipulating your resources and affecting your influence. This is represented by your limited dice rolls.
