I'm not much into playing roulette, or at all for that matter. But if I had a system with the game I would surely give up my hints.
What I've heard, was, that if you bet on the bottom color lines, or areas on the table, you can get a little of your money back, if you get lucky.
Roulette is all luck, since all a player can do is place a bet on the table.
The casino has the house edge on this game, most of the time.
So, if anyone has a Roulette system to help Salvador with, I'd be glad to hear about it too.
