There are a few Cityville cheats and exploits that you can use to rack up the coins. However, you always have to be careful with these things, because I’m pretty sure Zynga is going to notice if all of a sudden you have a few million coins. What I recommend instead is picking up a guide for the game — specifically, I recommend getting “The Best Cityville Guide Online” by James Green. Not only does this product have some awesome strategies, but it also actually has a complete collection of some of the best cheats, hacks and exploits for the game. The author has contacts to some of the best flash game hackers around and has a lot of links to cheats, as well as some in-house stuff.
