The cards are for rewards like free rooms and meals.  I used to make enough playing positive expectation video poker to pay for my flights and as many trips as I wanted as long as I played 8 hours a day.  I got many free rooms and meals as comps using cards with a girl I&#x27;d take with me.  Sadly too many people figured out how to play positive expectation and make money and the paytables have changed to where it&#x27;s not as easy as it was 15 years ago.
