You may loose several bets in a row to a ball landing on the one line you diddnt play or on 0 or 00 but overall this system statistically should win. If the stat I saw was right 31.8% this should mean that the odds if you pick two of them is 63.16% If the ball lands on any one number on those two lines you win 2-1 which means you loose one bet and tripple the other giving you a gain of 1 betting unit per bet. The few times I have been to casinos with real roulette, I play two of them usually the outside two. I believe I saw on one site a stat of 31.8%.
On a street (I believe im using this term right, I mean the pay lines at the back of the table as in the line 1 4 7 10 13 16 19 22 25 28 31 34) on each line you have a little less than 1/3 chance of winning. On a normal roulette table there are several ways to bet, some of the odds are seemingly good (17-1 53-1) but I prefer the 2-1 bets, these are streets and the 12s.
I know some of the members on this site have coding expeariance as does the site owner and I just want someone to proove me wrong, if I am! I don't care who knows about it and I'm not trying to sell it.
