Roulette is a game of luck, but it doesn’t hurt to have a little background knowledge about the game as highlighted on Chatroulette. Although you can’t win all the time, there are preventative measures you can take to stop yourself from losing too much. In the end, experimentation is the key to a roulette winning strategy.
Detecting bias on a wheel is a major way to affect the outcome of your bets. Each possible number is represented less than 3% of the time on the average European wheel. Because it is so small, this probability can be easily changed by any one source of bias on the wheel.
Statistical inference is useful for detecting bias. To detect this takes a lot of observatory skill. Many casinos have cameras on the tables. This insures that they will detect any possible bias before a player can. However, in some casinos and people roulette areas, a chi-square test of goodness of fit can be a player’s friend after careful observation of a wheel.
Beware misunderstanding the law of large numbers. The law of large numbers, also known as the law of averages, states that as the number of trials increases, the chance of several different outcomes become closer to their true values. For example, a coin flipped 10,000 times will land on heads and tails more equally than a coin flipped 10 times.
Many people, however, understand the law of large numbers to mean that if heads comes up 7 times in a row, the next 3 flips have to be tails. This is not true. The truth is, every outcome will have the same chance of occurring, except in cases of bias mentioned above.
This is why keeping to a few numbers in straight-up bets for many turns is better than changing your bets each time. The true value will restore itself over time. Changing bets according to trends that aren’t significant will not help your chances.
Vary your methods of betting as well. There are many types of bets that you can choose from, under two main categories. Inside bets include the straight-up single number bet and many others. Outside bets include even or odd, black or red, and dozen bets.
There are two types of wheels. Usually, casinos offer both types: American and European. Change your bets accordingly, but play more often on European tables if possible because they offer the player the advantage of having only one zero.
Play with ‘en prison’ or ‘surrender’ rules on the table. Under these rules, you will get half of your money back on all even money bets when the ball lands on zero.
