The game has pretty good payout after you first installed the app. In app purchase price was reasonable. But after I start spending money and leveling up, the payout is getting worse and worse. After reaching level 3000, every daily mission needs trillions of coins to complete, which is not possible without spending money. So basically there's no goal in this game, you just keep spending money and spin for maybe an hour and lose all, then repeat day after day.
