After downloading the game , the slots that are available play generous. But once you get up in the millions the winning slows down. I reached the billions through bonuses and completing tasks,then you start losing way more than winning. You lose 3, 4, or more times than winning. And then they ask you to bet more money to unlock this or that and you still lose yet more money. You dont win major or grand jackpot, a minors or 2 but mostly mini jackpots. Uninstalling.
