It's a very addictive game but a total bloody rip off. There are too many ads, which is extremely annoying. It gives you the option of paying to remove the ads, which I foolishly did. I am $13.99 poorer and still get bombarded with the same amount of ads. It just keeps trying to get me to pay more money to remove the ads, and when I wouldn't pay more, the game has now become unplayable.
