For me, its just luck.
Give it a shot and see what happens. Try the Freemont street roulette tables. The main strip has very few $5/$10 min tables. I think some of the big ones have $10 on Sundays.
Since you feel the math dictates it is not worth it to try, then that's fine. It's obviously your choice!
I don't think you are getting it.
Let's do a theoretical game here. For this game we will assume that I always win.
I will bet $10.00 every time split across the table only on $1 corner bets. These bets will not overlap (only 1 bet can win)
I will play using $50 until I am busted.
