Equal parts fun and frustrating, but that's the nature of being randomly assigned pieces.What is most frustrating however is the ads. There are a lot, with banner ads during games and full length video ads between them. I have not bought the paid version, but from what other reviewers have said that only seems to remove the banner ads, not the video ads, which are much more painful. Additionally, the PC opponent takes a very long time to make its move, sometime upwards of a full minute.
