I changed my comment from the prior. I was upset about items disappearing. It has not happened since. I made it to the end & am now waiting for new puzzles to come out whike going back replaying the levels where I did not get 3 stars and am still entertained for hours. How do you get the 3 stars? Ive noticed it seems to change. Sometimes I get it by making balls drop fast, by using less balls or sometimes more. Also I don't think getting the jackpot is available, I've never got it as of yet.
