This year you have to earn 25 base at each property, last year it was just 1 base credit. Last year there were a lot of people that took other peoples cards a played at other properties to get points . I would venture to guess 50% of the participants last year did not actually meet all the qualifications but still got the max payout. It's kind of interesting when you will see someone had play in Las Vegas the same date and time they have play in Iowa .
