 Thursdays from 8 a.m. to 12 a.m., guests earning five points or more in slot play will have a chance to play a kiosk game. Head to the promotional kiosk, swipe your card, enter your pin to play, and reveal your share of up to $40,000 of free play. That's 40,000 ways to beat the heat at Royal River Casino. Guests can only win one time per promotion stay. Royal River must be 21.
