Progressive, all the way back to 1,000,000 BC

Single-payliner Major Moolah was an incredible success for the Rivalers and for at least one lucky player who bagged over $50,000 the following month.
Second up for Rival was Strike Gold, similarly styled to Major Moolah, but on a goldmining theme.
This month, One Million Reels B.C. joins the small crowd (hey, three’s a crowd, right?) of Rival progressives, but this one is actually the company’s first 5-payliner.
Wonder what they’ll think of next…
