Without false modesty it can be said that Roulette takes the second place in the list of the most popular Internet casino games. The absolute leader of this list is slot machines. Since the time of the invention of cinematography, and later television, even those people who are not keen on casino have some basic knowledge of roulette.
If we don't go into details, and look only at the general rules of Roulette game, they can be described with a couple of statements: placing a bet, waiting for the end of a spin and depending on the number which drops out, either losing, or winning. But this is just a superficial glance which doesn't reflect the entire complexity of the game.
It is enough to say that there are several types of Roulette game and each of the type has its chances of winning. It means that each type of Roulette has its own so-called "casino percentage". For example, American Roulette has the casino percentage of 5.26, European Roulette the percentage equals to 2.7, French Roulette it equals to 1.35. For better understanding of the notion, "casino percentage" can be described in the following way: in a long-term prospect while playing American Roulette, casino takes 5.26 dollar out of each 100 dollar which you bet. In European Roulette casino takes 2.7 dollar from each 100 dollar whereas in French Roulette it takes 1.35 dollar from each 100 dollar. Don't forget that this is a percentage of the total bets made by all players on roulette for a day.
If you play for example American roulette using the system you can increase your part of remaining 94.74%. In other words if today players spend $100 on roulette in some casino then you can count on winning up to $94.74 in it. Keep in mind that the rest of 94.74% will spread between all players, and roulette system will give you an advantage of others. So basicaly you don't challenge casino but you challenge other players. And yes house always wins! But this is only in theory. Practice shows that in reality there can be different situations.
