. The add-on in the free version of the Rockstar Riches slot is triggered when you arrange 3 Ticket symbols in activated strings. Simply put, Rockstar Riches is one heck of a winner, and this game should absolutely be the next video slots game you play. The betting menu for Polar Riches real money wagers is set up a bit differently than other Amaya slots. It is a 2-part bet that requires you to first select the credit value (from 0.01 up to 0.25). With each bet level you add, you increase your bet by 20 more credits (one per payline). A minimum bet at the 0.01 credit value, at level 1, will cost you 0.20 credits. At that same credit value, you can move up levels, up to 10, for a 2.00-credit bet.
