TREATICE ROULETTE SYSTEM
Roulette, with its hypnotically spinning wheel, perhaps best exemplifies the turn of destiny.
Poker and blackjack players often deride the attempts of roulette players to devise consistently winning systems for roulette, pointing to the law of dependent trials and stating flatly than no system can beat roulette. In fact there are a number of scientific and workable methods to attack the game.
The first and most popular method is known as "biased wheel play". This depends on the delicate mechanical structure of the wheel. Roulette wheels are very expensive. A casino cannot afford to jettison one every time minor flaws develop.
Imperceptibly and over time certain pockets become favoured. Perhaps a fret becomes bent. Perhaps a screw loosens.
An obvious bias is quickly repaired but subtle mechanical imperfection is difficult or impossible to detect by visual means alone.
A player who records the results of multiple spins may reallise that certain numbers occur more frequently than chance would dictate. If a number occurs more than an average of 1 spin in 35, it is favourable. Over a long enough period of trials betting on such a number will yield profit.
The second is known as "dealer's signature". This requires a dealer whose throw is so consistent that he can direct it into a certain area of the wheel. The player collates data on the average number of revolutions of the ball and rotor with a particular croupier and uses the dealer's predictability to make winning bets.
The final method is known as "wheel-watching". It requires the bettor to ascertain the speed of the ball and the rotor relative to each other, and the position of the ball relative to the target numbers on the wheel. Then the average point of the fall of the ball into the numbers is determined.
It is important point to note that if you knew just one number would not come up (two in the American game), then roulette would be a dead even game. Anything more and you have the advantage. That house edge is very fragile.
