Just as much fun as the previous games but the new ads are very frustrating. Especially the ones that automatically install an unwanted app just for touching anywhere on the screen, even when closing the ad. I actually paid on the previous game because I played it so much, but the new format is such an obvious "pay to win" model that I refuse to spend a dime on this one. As soon as a random ad pops up, I close the app and reopen. Grinding for upgrades isn't a terrible idea. But not the right one
