Bahaha this is exactly why I don't gamble; I know I'd get hooked chasing that big win!
That said, it's remarkable how close your win, lose and tie amounts all are. I'm used to most programmed gambling (anything that involves a computer dishing out the results rather than, say physical cards or something) skewing more heavily in the house's favour.
