However, you can improve your chances of winning by fully understanding the roulette odds and payouts that are involved. HOWEVER more people claim to do it then actually do it profitably (a la blackjack card counting).When you play roulette, you are taking part in a game of chance in which no one knows where the little ball will end up. You can cover this range with two simple bets ('.and the neighbors' bets) each spin.Ĭasino's do watch players who do these types of bets with certain dealers, and good casinos switch and rotate wheels regularly to prevent clocking (as well as training dealers properly). Experienced dealers who are not bothered randomizing behavior slip into a pattern where the ball tends to spin the same number of times and bounce first in the same region of the wheel.īecause of item 3 above, it is possible to clock certain dealers and determine which parts of the wheel are slightly +EV.įor example a player determines that a dealer hits the 10 number range that is a quarter turn to the left of the point where the ball leaves there hand with more than the expected frequency.

Due to spread of odd/even and red/black and low/high it is difficult to spot if that's all you are looking for, and even if you know what to look for it is difficult to find as it's usually very close to undetectable, and if it is detectable it is very hard to exploit as they change the wheels and variance creates a lot of noise.ģ.

Casino's do collect data, and switch wheels regularly.Ģ. Do you think that such an approach could mean +EV?ġ. What's the probability that a series of 8 blacks (or more) in a row will happen during the next say 221 consecutive spins? You start to chase a series of 8 blacks in a row with a Contre D'Alembert strategy. Now let's assume you watch a roulette wheel and discover that 'black 8 times (or more) in a row' did not happen during 953 consecutive spins.

This means, with a probability of 50% 'black 8 times in a row' will happen once in 221 consecutive spins (on the average!). We said (for the case of the European wheel) that the probability of no black 8 times in a row is (19/37)^8 =~ 0.484% or about 206-to-1. One example for a big roulette gambler's fallacy at an HONEST roulette wheel:
