Looks like my previous post was deleted! There seems to be many complaints and issues with this game. I noticed that to double up coins by advert is never available except usually under 50 coins . I had said in my last post that this game becomes very expensive and I believe the developers really need to take on board the game users comments and look at making the changes. I will be deleting and hope that when I reinstall in the future the play has improved vastly.
