How long is your typical roulette session and have you tracked your overall win rate? For a game of chance that favors the house, would it be reasonable to expect to basically break even (or lose slightly) over time?
£540 - a mad xmas in 2009 - 20p roulette machine and i could not step away from my favourite numbers 0/14/ 17/20/34 and i went on a mad run - ended up taking me and 3 pals out to a local curryhouse after and spent £140 on a meal and drinks. I think i got away lightly there
