Although it holds true that if we spun the wheel numerous times (or close to the infinity), then the red should come up at approx. Roulette feels no incentive to change the color. As it may seem like a paradox and as it can be expected 'in reality' that the color will change at last, from a probability point of view it is completely groundless to assume that the color, which has not come up for a long time, is now more likely to appear! More precisely, if we play French Roulette with 18 red + 18 black + a single zero (there is an extra (double) zero in American Roulette, which only worsens winning chances), then the probability to win a bet on a color is always 18/37 = 0.4865 = 48.65%.īoth colors can come up with still-the-same probability. There is a saying that might be very handy for you to remember: ' Roulette has no memory.'Īs every spin always presents a brand new event, red or black color can come up with the same probability at any time during the course of play, regardless of the fact that one of these colors has come up e.g. Every unique event starts over again regardless of the past. And this is the point of the whole illusion or one might say delusion. Each Roulette spin is a new or unique event.

If we forget about a zero (which is marked green) then the outcome of this event may be either red or black color.

Unique EventĪn event (a standalone / individual / unique / new event) is a designation for a random trial such as e.g. This time is worthwhile to familiarize with two terms: a unique event and a series of events. If for example a black number (any of the black numbers) came up ten times in a row, do you think it would raise your winning chances if you bet on the red color? Unfortunately not. For novices to Roulette: each number has a fixed color that does not change and croupier announces the winning number and its color, for instance 'Seven, red'. Why do you think the casinos show the statistics of the past spins? Do you think that such statistics has a practical value, not to say can be used as a guide for prediction of the upcoming numbers and thus their colors. This illusion is also promoted by casinos.
