What are the best games on IWon.com?

Tweet

I was a member of IWon.com back when it first started, then recently (within the past few days) got back out to the site and have been playing the games there when I am looking for diversions. I was wondering which games others find to be the most fun to play and why? I enjoy playing Turbo Solitaire, Mah Jong, and Collapse. Today when I was looking at different games to try out I discovered that Magnet Words is also very addictive. Which games do you find to be good for a few minutes of fun distraction and have you ever actually won anything from playing them, or do you just play because they are fun?
