Rob, I will never be able to match your pictures of big winners because I don't play at your high denominations. But I can probably match you -- picture for picture -- with "great wins" if you included my play at 25-cent and $1 games -- not to mention my dealt royal on a 50-play machine at 5-cents.
The point is -- you are not such a big winner. There are plenty of casino players at 25-cent games who have had more royals than you've had, and more big winning hands. Just on my last trip to Rincon I sat by a lady who hit two royals just ten minutes apart. I'm not sure what denomination she was playing but her machine started at 25-cents and went up to $1 and even the 25-cent royals need a hand pay.
