Dominion: Intrigue expansion adds 25 new Kingdom cards to the main game, Dominion. There are victory cards that do some new things for you, underling that give you a choice as to what they do, and a variety of other people and places. These cards can be played with the cards from the basic game or on their own. The rules include how to play a game with up to 6 players. By combining the money and victory cards with those in the basic game, players will have sufficient cards to play with more than 4 players.
