To successfully play in 
                                    the casino, of course, need to know and to 
                                    choose the right games. It is clear that the 
                                    players have a personal preference: some 
                                    like slot machines, someone is looking for 
                                    opportunities to win roulette, and someone 
                                    who likes card games. But all games have 
                                    some of the characteristics, properties, and 
                                    if you want to play well, you should choose 
                                    the "right" of the game.
Since casino games are 
                                    random in principle, then, as any random 
                                    events, they are described by the parameters 
                                    of the expectation and variance. The 
                                    expectation (or payouts) shows the 
                                    percentage of bets placed on the average 
                                    player get back. Most often it is 95-99%, ie 
                                    casino games designed so that the casino has 
                                    the advantage of a higher probability to 
                                    win. These are the rules of the games.
                                    The dispersion characterizes the dispersion 
                                    of the results of the game, the magnitude of 
                                    the possible deviations from the 
                                    mathematical expectation. If a game with 
                                    high variance, then the player can both lost 
                                    heavily, and the biggest gainers. In a game 
                                    with low dispersion player will often 
                                    fluctuate around the initial sum.
In addition, the casino 
                                    games are divided into the "game of chance" 
                                    and "games of skill". In games of chance a 
                                    player makes a bet and then nothing of it 
                                    depends. In this case, the player can not 
                                    change the expectation game. 
                                    So random 
                                    roulette, unfortunately for many, it is 
                                    impossible to beat. Various betting 
                                    strategies (Martingale, Donald, etc.) change 
                                    only the variance, but not expectation. In 
                                    games of skill after the bet the player 
                                    takes a decision (to change maps, 
                                    continuation or completion of the game), 
                                    respectively, the solutions may be optimal 
                                    or not. Mathematicians have calculated the 
                                    most profitable activities in different 
                                    situations, all together they create a base 
                                    or an optimal strategy. 
                                    In fact, there are techniques to really gain 
                                    an advantage over the casino, but more about 
                                    that in the article.
