House advantage. Casino games typically provide a predictable long-term advantage to the casino, or 'house', while offering the players the possibility of a short-term gain that in some cases can be large. Some casino games have a skill element, where the players' decisions have an impact on the results. The house has an advantage in blackjack simply because the player has to draw first and if he busts, the player automatically losses regardless if the dealer subsequently busts in the same round. This is the casino's solitary advantage in blackjack and if everything were equal, the house edge in blackjack would be about 8 percent. In some cases, using a basic strategy can reduce the house edge to just 0.5%! If you want to lower the house advantage, studying the basics of blackjack strategies is a good place to start. In addition to basic strategy charts, several strategies have been developed to.

We begin this Blackjack guide with a very important assertion – casino games, hence the name, are designed with a built-in house advantage – a casino's edge in odds over a player at any given bet.

Thus, by stepping into a casino, you know that the odds by default are stacked against you to a certain degree. This means that in the long term you will always lose money, unless you skew the odds to even or in your favor.

Casinos believe that as soon as you enter their premises, it is just a matter of time before all your money becomes theirs. And since they want to keep you around for as long as possible, they will attract you with the so-called comps – complimentary items and services given out by the house to encourage players to gamble.

Casinos will do everything they can to make you feel cozy, valued and inclined to prolong your stay at the tables. These “freebies” they give out depend on the game a person plays, for how long, and of course on the size of his bets. Casinos have staff whose job is to manage the comps and contact players to persuade them to visit and play.

As a casino game, Blackjack also falls under this principle and is designed to transfer the money from your pocket into the house's vault, unless some method of advantage play is used. This is where this guide comes in.

We will present ideas which will can help you shift odds to near-even, and in some cases even slightly in your favor. This will be done in the first section of the guide where we will discuss strategies relating to the basic strategy player.

Later on we will move to the so-called advantage player, where card counting takes place. Whereas the basic strategy player is on relatively even ground with the house, albeit still behind, the advantage players, hence the name, have an advantage over the casino as soon as the game begins.

House Advantage Casino Games

Regardless of which type of player you want to become, both require the aforementioned “method of advantage play” – strategies, card counting etc., which help skew the odds out of the casino's favor.

Blackjack is one of the most widely played casino games for several reasons – it has simple rules, it is offered by almost every casino and most importantly – offers the best overall odds for the player, even for the non-advtantage one. It is simply a game that falls under the principles of odds and probabilities and can be beaten through lots of experience, knowledge and skill.

Odds and probabilities

Now, one would wonder how come if the stacks are always stacked against the non-advantage players, who make up most of the player mass, there are still many people going to the casinos. After all, if all these people were constantly losing, they would ultimately become discouraged and the majority will stop playing.

Gamblers hope that on any particular night they might be lucky and the odds fall in their favor. For example, although tossing a coin has a 50% chance to turn heads or tails, when you toss it only 20 times, it might land 14 times on heads and 6 on tails. The even probability of tossing tails or heads is true only when you repeat the exercise enough times to ensure a large enough sample pool.

And because many people get lucky at any given moment, they will earn money, fueling their excitement and luring them back in the casino the next night. And although this causes the house to lose money, the casino relies on the fact that players place millions of bets, which irons out the outcome in the long-term and makes the house profitable. In mathematics, this is known as the law of large numbers.

This rule dictates that the more bets are placed, the closer the casino's odds will come to the artificially created built-in house advantage, thus the more hands (bets) a non-advantage gambler plays (places), the smaller his chances to win become.

Thus, players who do not employ advantage methods will be losing money if they continue to play in the long-term, which allows casinos to continue to operate, while basic strategy and advantage players profit from their efforts.

Calculating the house's advantage in blackjack is difficult due to the huge amount of card combinations and also because not all winning bets have the same payout (for example, a blackjack which is a 21-hand with an ace and a 10-valued card, pays 3:2 in most casinos).

The extent and source of the house's advantage varies in different casinos. In blackjack, for example, it is derived from the fact that when the player busts himself by exceeding the count of 21, the house wins the bet, regardless of whether the dealer would also bust when drawing more cards to complete the hand for other players on the table.

Improving or reducing the house's advantage

The house edge depends on the rules the casino has established for the blackjack table and they are posted and easily visible either on, or near the table.

For example, a casino where dealers stand on a soft 17 (S17), instead of hitting it (H17), favors the players' odds, reducing the house's edge by around 0.2%. Increasing the number of decks also increases the house's edge, and vice versa.

The implementation of other rules such as the allowance or disallowance of resplitting, doubling down after split, double on 9/10/11 or only on 10/11 and so on. Casinos typically aim to boost their advantage but also not to discourage players from joining the game and, thus, seek some form of balance. For example, if they offer one-deck blackjack, they typically forbid doubling on soft hands or after splitting, restrict resplitting and so on.
