DominionStrategy Wiki
It's great for killing time if you're a fan of Dominion. The only problem I've found is that since the AI is so tough you end up playing an extemely aggresive game and you don't get the real genuine fun of playing it with other people. If you want to beat the AI in this app you don't have time to buy and use the majority of the cards in the game to try different strategies, you're rushed into hoarding silver/gold and buying VP immediately after 5 or 6 turns.
