The percentage used is the equivalent real (not theoretical) the house edge. If the benefit of the house was maintained and that all games were held as planned statistics, the percentage of restraint and the benefit would be equivalent.

However, this may be misleading because for games such as slot machines, where there is no variation, the percentage of retention is really the equivalent of house advantage. In fact, the calculations on the slot machines are based on data rather than probabilities. Tables, if we consider, for example, the odds at blackjack, the possible outcomes of a game are more numerous.

This affects the value of the benefit accruing to casinos at different times. The percentage restraint takes a slightly different meaning at the blackjack table. This is the amount the casino keeps the total bet on the table. This is an actual amount determined and not a theoretical value as that of the benefit. Variability is caused by such things as the time during which the players continue to build from an initial purchase, or the importance of their bets against portfolios, etc..

One wonders how all this relates to the chances and probabilities in blackjack. This makes the player aware of the benefits of the house through the casino and he can see quite clearly how and why blackjack gives the player a clear advantage, an advantage variable, that it can control.

At this point, you understand that the goal of every gambler is to significantly reduce the percentage retained by the house during the game session the only way to do this is to change his style of play to the advantage provided the house is statistically lower (which, in turn, decrease the rate of withholding from the house).

Players who use perfect basic strategy can succeed in reducing the house edge to a point where their chances are about equal to those of the casino. It is easy to find a blackjack game with an advantage of 0.5% or less for the house when you know what to look for and how to play properly. The player who does not use any strategy and is essentially on intuition will see the house edge is somewhere between 2 and 5%. Many people believe that the only use of basic strategy amounts to nothing more than use any strategy.
