Hades has kidnapped all of the Greek Goddesses. In order to save them, you must beat the God of the Underworld in various games of solitaire. I have to say that the game pretty much delivers what you would expect. Each goddess has a different variation of solitaire that you need to beat in order to rescue her from Hades. In between some of the levels, Hades tries to trick you with a card game. He shows you a card, mixes up all the cards and you need to pick the correct card. It's not particularly difficult.
Overall, the game is dull. It's fairly easy to beat Hades in each card game and when you do save the goddesses, you don't receive any sort of reward. This might be a nice change of pace if you play a lot of solitaire games but it's not something you'll be playing very often.
