Online roulette probability
Roulette is considered to be a classic gambling game of chance, which means that there is always some risk for players to lose irrespective of their efforts or knowledge about the game.
Therefore, it is important to be able to compute what online roulette probability of winning is offered in order not to be disappointed with playing results.
Let us look closer at the notion of roulette house edge and what it means for gamblers' winning possibilities.
Roulette house edge
It is widely known that casinos have a long run advantage over players and in case of roulette game the advantage is clearly seen if you consider casino roulette wheel design.
There are 37 slots in European wheel and 38 pockets in American wheel in total, which are designed for 36 numbers from 1 to 36 and for zero positions.
The sense is that in case of winning roulette players get their reward, which differs from true odds due to zero slots existence. To make it clear, let us explain the notion of casino's advantage by example of single number betting.
In case of making $1 bet on one of the 36 numbers your potential reward comprises $35 while online roulette probability of winning is just 1/37 in European game and even less 1/38 in American game. Further, assuming that you are lucky and win the most favorable bet, you get $35 and keep your initial bankroll of 1$. Therefore, the difference is $37-$35-$1=$1 for European game and $38-$35-$1=$2 for American play. These numbers present casino's advantage in nominal expression while it is common to convert them into percentages.
Thus, if divide $1 by $37 we get a familiar number of 2.7% house odds for European roulette and 5.26% for American game.
Decrease casino's advantage
Although gamblers are not able to change roulette wheel's design in order to decrease the house edge, but they are free to choose European roulette variation, which provides lower casino odds, and look for certain rules application (such as La Partage and En Prison rules), which allows to reduce the house advantage to 1.35% in European game and 2.7% in American one.
Moreover, different casinos could offer various roulette variations like Live Dealer Roulette or Biloxi Roulette with some distinctions in playing conditions, so you are welcome to choose the most appropriate for you.
