Epic Jackpot and many others are so much better. This game is not worth the space it takes up(freed up 1.5gig after uninstalling). You spend 5 minutes going thru the process of getting your 'free credits' only to receive 2-3 minutes of actual play time. The only people that accumulate billions are people that spend. Free game is an allusion. Far better slots available that offer way more actual free play. Decide for yourselves.
