Probably the most rigged slot game there is. I've played a lot of slot games and this is by far the hardest game to progress in. You can spend real money for a tiny amount of coins compared to other games. You can spend like 20 dollars and not even level up once. You can win a decent amount and then go on a 200-300 spin loss with no big wins. You really need to increase the amount of coins you get from spending real money by at least 100%
