I have had enough

This game does ads ten times per minute so I have had enough

New Updates

The new update to the game deleted my previous build. Not only that, but this new update is draining battery at an astronomical rate.

No more

Have not been able to level for a week now. Can make gold unless we watch commercials. It may be to delete and move on.

Top much ads !

Il could be fun but there is too much stupid ads and when you are about to get some gold bar it freez you with a White page !! Desapointing !!

Game big bug

Love to place all the town items. Easy to make more money. Long suffering videos to watch butโ€ฆโ€ฆ.then screen goes white red X does not return back to screen. States game overload and you can fix it. Well no you cannot. Not happy with the white screen. Only goes away for a long time. I just have to stop playing at that point. The game at that time stops. Not fun.
