From an experienced roulettes players point of view, Ill give you credit for using a system at roulette rather than relying purly on luck. Ive used this system myself when i started.In the short run youll win,however for long term gain the casino will send you broke. Ive seen combinations at its worst
rbrbrbrbrbrbrbrbr
rrbbrrbbrrbbrrbb
rrrbbbrrrbbbrrrbbb

your better off picking a combination yourself like rrbrbb and backing the zeros to cover youself in case it lands.

However that was just my 2 cents and I would never play roulette for long term gain.One of the worst casino games to play. Stick to Black jack.

another system ive seen used is if youve got a team.lets say 4.

youll need a bankroll of a few thousand. Rapid roulette. Many clubs have them. Max bet $100. Youll just back the same number round after round until 30 consecutive spins and your number hasnt appeared one of your team mates jumps on another terminal to play the same game. after a few spins without the number appearing another terminal is used and it goes on.

Dangerous method however ive seen it been used,and won.
