Super Roulette Strategy: Winning Free Roulette Systems. The FREE winning roulette systems in this collection are based on mathematics of Fundamental Formula of Gambling (FFG) and betting progressions. Accompanied by unique, dedicated software. A) The probability p for a single zero roulette game is: p = 1/37 = 0.027. We apply the Fundamental Formula of Gambling to one value of DC (degree of certainty): 66.6% (or 2/3, 2 out of 3 cases). For DC = 66.6%: N = 40.4 (rounded up to 41 spins). There is a 66.6% (2 in 3) chance that each roulette number will repeat after 41 spins. Equivalently, there is a 66.6% chance that the next spin will be a number that also appeared within the last 41 spins. B) The probability p for a double zero roulette game is: p = 1/38 = 0.026. We apply the Fundamental Formula of Gambling to one value of DC (degree of certainty): 66.6% (or 2/3). For DC = 66.6%: N = 41.5 (rounded up to 42 spins or 41 for single-zero wheels). There is a 66.6% (2 in 3) chance that each roulette number will repeat after 42 spins. Equivalently, there is a 66.6% chance that the next spin will be a number that also appeared within the last 42 spins. The column Last 26 Roulette Spins reflects a DC (Degree of Certainty - see FFG, Fundamental Formula of Gambling) of 50% (it is 25 for single-zero casino roulette wheels). In half the situations, the next roulette number would have also appeared in the previous 26 spins. I decided not to use a betting system based on a DC = 50%. The losing streak can reach sometimes 10-13 spins in a row. Also, the losing/winning streaks are far more irregular. Instead, I chose to base my gambling betting systems on DC = 66% since the winning/losing streaks are a whole lot more manageable. It works best at the command prompt for best speed; all 32/64 bit versions of Windows supported. http://saliu.com/membership.html http://saliu.com/Roulette.htm Absolutely the best on roulette, strategy, gambling, software, mathematics.
