Every time you even open the game to start playing, it's an ad before the app even fully opens, so you see their advertisers before their own game/app. Wild to give the app zero chance to run before the ads. You must watch an ad several times while you're playing also. About 50-60% of the time this app is open, it's just playing ads. Definitely uninstalling.

My daughter loves the game. However the ads are always unavailable, the one time they were we got hats and coins, the next time we played they were no longer there. Even the one we'd purchased was gone. Tried logging out and back into Facebook, restoring purchases and saved data but they are still gone. I got two blue gems for touching a virus, but when I switched worlds it took one away. It won't allow me to select the cloud save option.

The game is fun but it's impossible to do anything without ads appearing. It gives you the option to pay to take away ads but I'm not going to do that with a game I've only had on my phone for 5 minutes that I'm not sure I'm going to keep.
