Ok i do not know if i can post links or not in the forum so please do a search in google with the words "roulette cover 100%" and you will see the link to the possible scam site on one of the first places.
I searched in the forum but did not find any information about it, does anybody know how this system operates?
My friend, try not to focus on system that playing RNG.
And also, don't always rely on the reviews, sometimes they are competitors saying negative things about them.
Therefore you always have to figure out yourself, do your own research and make your final decision.
My first touch system was Roulette Sniper. It uses martingale method, wait for several number of times that a number or a group of numbers (outside bets) not coming up and bet for 1,2,4,8. . . ETC.
A system always has its own assumption, from what I observed, it based on a math theory, that one third of numbers will repeat itself. (something like that as I don't remember)
Anyway, The following are the issues that I consider before any further actions.
1. A winner system does not worth only a penny or a few hundred.
2. A winner system means if you are only playing flat bets, you can win.
3. A winner system does not require players to cut any losses and profits. The longer you play, the more you win.
4. A winner system focuses on long term goal.
5. Simply mathematics systems are not enough to "beat roulette", as gambling is not simply maths.
Have a nice day!
