Bets for pink or black, odd or even, 1 to 18 and 19 to 36 are all even money bets. These bets offer you a fair chance at doubling your cash in roulette. But in American roulette the double zero offers the house much more of an advantage than it already had with just the one zero. The fundamental principle of this betting system is predicated on the chance principle. You will be ready to use this betting system solely in those on-line casinos where you are allowed to skip a spin, not to wager.
