100% a pay to win game. If you don't pay you won't win any of the mega jackpots. They say it's random but I have proven it's not. Two accounts over 6 months on each never won a grand jackpot. Talked to other free players none of them have hit the mega. My best friend played spent money in his first month and hit the grand jackpot on a machine. And most other p2p players have hit at least once. Don't listen to the lies this games developers tell. 100% a pay to win game.
