Is Dominion Online still online?

Dominion is a card game created by Donald X. Vaccarino and published by Rio Grande Games. Originally published in 2008, it was the first deck-building game, and inspired a genre of games in that category. As of 3 October 2026, sixteen expansions to the game have been released.

In Dominion, each player takes turns drawing from their own personal deck of cards. Each player's deck starts identical, but players can purchase new cards from a common supply to upgrade their deck; these new cards can then be drawn and used on future turns. Players seek to build the strongest deck with the most victory points needed to win the game.

The game has a medieval theme with card names referencing pre-industrial, monarchical, and feudal social structures. It is possible to compare the game with collectible card games such as Magic: The Gathering.

When Dominion was released at the Spiel game fair in 2008, it was voted "best game of the fair" by the Fairplay polls. The next year it won the Spiel des Jahres and Deutscher Spiele Preis awards. It was one of five winning games in American Mensa's 2009 MindGame competition. By 2017, more than 2.5 million copies of Dominion and its expansions had been sold worldwide.
