You are correct. The scratch cards are for 4 of a kind or higher. My husband managed to get his first straight flush on our last trip there. We even had a few scratch cards for more then $2. You do need your card inserted and be playing all 5 credits of course. Mary
If anyone doesn't want the Slot Attendant to take your card out of the card reader to take down the card number, you can always have a duplicate card on you.
