Much luck involved. The thing I did was placing one bet on a number low single number, one bet on all the high numbers so I spread the chances among the two. Also, I didn't play every round of the game - sometimes I'd bet nothing or a few rounds and that could help a lot as the others did loose a couple of hands.
BTW - I hate Keystone.
