Nothing wrong with making a good play and winning. You should hang out at Caesars. Once I was playing video poker in the "small dome" (one of the high limit areas) and I get a tap on my shoulder. It was a player who was playing Ultimate X on the kiosk behind me. He said he ran out of money and pointed to the screen. It was a three-play game showing multipliers. He said "do you want to play this?" I politely said "no thanks" and continued at my game.
Now, I have to admit I didn't know what the game was, and I had no idea what it meant to have multipliers left on the screens. After I learned about these leftover multipliers I've looked for them and yes, they show up at the $1 and $2 machines at Caesars. But I still don't play them because when I see them it's because another player is rushing to take the seat and the sight of them rushing to the seat is what gets my attention.
So yes, they are out there.
