I just got done playing a little 5 play super aces on winpoker. In 150 dealt hands, 750 hands total, I hit 2 royal flushes, quad 3s and had 5 straights dealt, along with a dealt flush. Even though I only played at .9997, I still was up 8115 coins.
Streaks happen both ways. I could have quit after the first royal and locked up my profit but you don't know what the next hand will bring. The 2 royals were about 25 dealt hands apart.
