I've had two, First was Downtown. I had just arrived in town, and went to meet some friends who were already there. Didn't feel like gambling yet so I watched those guys gamble. After awhile, I wanted a water, so I went to the bar. I plopped down, and tossed a twenty into the VP machine. First spin, AAAA. It was a progressive machine, so I won about $125. I walked without the water. Second time. I was at Orleans, and was having a decent day. I decided to head to the room, but stopped by the High Limit room to toss a hundy into a $2 DDB machine. Dealt two 7s, and drew the other two! Cashed out the $595 and beat feet!
