Not easy! Defiantly not relaxing, but challenging. The only reason I gave it less than 5 stars is that there are commercials. The game just STOPS and you have to watch a commercial, and lose your concentration. I'd rather watch all the commercials in between games. Come on, really? I know you make money by the commercials, but also to pay to remove them? I don't mind commercials, just not in the middle of a game!
