Roulette and probability

by Rebekah Macon (2019-04-25)

Like most simple games, roulette allows a very high house edge. The American variant of roulette is by far the worse as it has two zeros involved. This means the house edge is 5.26%, in real terms this means for every £100 bet, £5.26 is profit for the casino. European is much better as it only has one zero to contend with. This means the house edge is roughly 2.7%, in real terms this means that for every £100 bet, £2.70 is profit for the casino. So how can we beat roulette when the odds are clearly tipped against us?

Popular perception believes in probability, if you play poker, then you are probably familiar to the theory of probability. The theory works like this: the results are usually predetermined by the prior outcomes. This works perfectly in poker where the odds follow a clear mathematical formula. But it is very unlikely you will beat roulette with the theory.

The theory probability cannot beat roulette. The reason for this is because the outcomes do not rely on the prior spins. So you can never beat roulette using probability. Let us say that you bet on 8 and tembak ikan the first spin shows a 10. This does not mean that in the next spin, you only have to grapple with 36 odds since 10 already came out. There is still every chance that the same number will come out after the spin. The wheel has no memory and do not forget this.

With numerous claims from many websites of new-fangled roulette strategies it is not surprising people think roulette can be beaten. But in reality the truth is roulette cannot be beaten, it is completely random and has no past, the odds will always stay the same and no theory of probability will ever work. Play roulette for what it is, a game of chance and luck, trying to beat the wheel will eventually end in your financial loss.
