One of the newest solitaire games available online, Solitaire Farm: Seasons, promises hours of entertainment. The level is cleared if you correctly draw a card, which entails matching all the cards up to the point where there are none left. By clicking on the deck, you can add fresh rows of cards if you run into trouble. You'll accomplish this over a number of stages that, although appearing to mimic the changing seasons of the year, really get harder over time. Enjoy!
