Lasvegaspilgrim - BTW how did you become aware of the multiplier, since there were no signs up?
I saw that the 6x multiplier was available to me when I swiped in the kiosk. I do this before I play at all Boyd casinos.
P.S. I did their Tuesday Swipe-and-Win at Suncoast earlier this month and my prize was a bowl of soup at the Bagel Cafe. I think this is the oddest swipe-and-win prize I have ever gotten. And no, I didn't get the soup. I just threw the voucher away.
