DEVIATIONS. (first part)

WHAT IS A DEVIATION?

The deviation is the pet hate of the roulette players, especially for those who use martingales. A deviation is a series of losing spins. It is the most dangerous phase, the one that may finish you off. There you can meet the famous point of no return.

ARE DEVIATION A COMMON PHENOMENA ?

Deviations can be significant and appear several times during the same game or evening.
As we discovered in the section about the random phenomena, a colour can come out up to 12 times consecutively! This also means that the other colour hasn’t come out till that number of spins! (deviation = 12 ) Of course, this situation is quite unusual BUT it may occur!
Imagine yourself facing this situation while using a classic martingale.
At the 12th spin, you should place 2048 chips on the table and if you win, your gain will be equal to one single chip. That’s quite a lot of money at stake, isn’t it? Particularly if you have placed as starting bet a chip of 5 $ or 10 $. If the situation « deviation 12 » is uncommon, a deviation of 5, 6, 7 or 8 is quite usual. You will experience this while using our interactive tool.

A DEVIATION OF 8, the number of chips...

As it was demonstrated in the table above, for a deviation of 8, you will have to double your bet 8 times consecutively and stake 128 chips after already have lost some 127! (bets: 1, 2, 4, 8, 16, 32, 64, 128, 256) You total investment is equal to 255 chips. If the chips is equal to 10 $, this deviation is worth 2.550 $!!! At the first winning spin, let’s say at the 9th spin, you will only win one single chip.

CAN WE INCREASE THE BETS?

You must to be careful because some casinos limit the betting. That means that you can’t place on the table more than a certain amount of money per bet. With progressive martingales, the risk is that at some point of the game, you cannot raise your bet anymore and you will lose everything! Consequently, you will need a lot of money, not to be limited by the casino and to have a lot of pluck!

DEVIATION ON DOZENS

The phenomenon of deviation is the same for all the random games.
It is possible for a dozen not to appear 12 times consecutively. (We have already met this situation while playing) This absence can occur 1 time on 2000 spins in average.
While betting on dozens, the absence of a dozen can last during 9, 10,... 13 spins.
In addition, this phenomenon is quite common. You are then in a critical situation.
You try to find the equilibrium but unfortunately those phases of deviation don’t disappear.
You will probably lose patience and quit!

WITH A GRAPH...

You can bet at each spin, once every two spins or once every 20 spins! The scheme is always the same: a switchback graph, with losses and gains.

The interactive tool In this graph, you have lost 187 spins with a maximum deviation of –32 chips. Then, you have experienced a winning phase of +22 chips. If the bets are not limited, the deviation can go down up to several hundreds of chips! You will then see that, in every phase, there are switchback movements. In a long phase, you win and you lose without being able to come out of a losing phase. In this game, using a classic progressive martingale is not possible. Fortunately, contrary to this graph, you will experience winning phases as many times as losing phases. This is the law of equilibrium, the law of the large number!
