Rappy Slot Rates

Been at the slots for over 29 hours now and still haven't hit the jackpot. Best match I've gotten is 7 Wild Symbols twice. Does anybody know what the odds/rates are and which ones got boosts or not? Casino seems dead on Ship 1 so I haven't really been able to gather much data.

@Neith-Sais Not sure on the odds, but here's a post outlining one player's observations during one of the Rally Slots casino boost events (next one is tomorrow from 1-4pm Eastern Time).

Thanks. I guess I'll go back to grinding.
