Every thirty seconds there's an ad. Completely unplayable. False advertising on the app store, too. It says you can unlock Europe and play there, but you can't. Waste of time, and a sorry excuse for a game. I'd give it negative 5 stars if I could. I played through once with my wifi off so I could avoid the ads, but when I didn't unlock Europe, I thought maybe I have to get all the roads possible. But now that I'm playing it again it REQUIRES wifi, and is absolutely annoying.
