Disappointed with interaction with the characters, apart from click to upgrade there is nothing to do. Very boring. Very very boring waiting to generate enough cash to upgrade a tiny bit then very boring again until you generate enough money for the next upgrade... Yawn. 1 star for game play. 3 for graphics 0 stars for game rewards via adverts, sometimes no pay out sometimes less than advertised reward. What's the point in a riot if you can't interact yawn 0 stars, dangerous prisoners ha 0 stars
