This guide, written by casino math professor Robert Hannumcontains a brief, non-technical discussion of the basic mathematics governing casino games and shows how casinos make money from these games. The article addresses a variety of topics, including house advantage, confusion about win rates, game volatility, player value and comp policies, casino pricing mistakes, and regulatory issues. Statistical advantages associated with the casino advantage games are also provided.

Selected Bibliography About the Author. At its core the casino advantage of casino gaming is pretty simple. Casinos make money on their games because of the mathematics behind the games.

As Nico Zographos, dealer-extraordinaire for the 'Greek Syndicate' in Deauville, Cannes, and Monte Carlo in the s observed about casino gaming: It is all mathematics. With a few notable exceptions, the house always wins - in the long run - because of the mathematical advantage the casino enjoys over the player.

That is what Mario Puzo was referring casino advantage in his famous novel Fools Die when his fictional casino boss character, Gronevelt, commented: We built all these hotels on percentages. We casino advantage rich on the percentage. You can lose faith in everything, religion and God, casino advantage and love, good and evil, war and peace.

But the percentage will always stand fast. Puzo is, of course, right on the money about casino gaming. Without casino advantage "edge," casinos would not exist. With this edge, and because of a famous mathematical result called the law of large numbers, a casino casino advantage guaranteed to win in the long run.

Why is Mathematics Important? Casino advantage of the gaming industry have long accused it of creating the name "gaming" and using this as more politically correct than calling itself the "gambling industry.

Instead, they rely on mathematical principles to assure that their establishment generates positive gross gaming revenues. The operator, however, must assure the gaming revenues are sufficient to cover deductions like bad debts, expenses, employees, taxes and interest. Despite the obvious, many casino professionals casino advantage their advancements by failing to casino advantage the basic mathematics of the games and their relationships to casino profitability.

One casino owner would often test his pit bosses by asking how a casino could make money on blackjack if the outcome is determined simply by whether the player or the dealer came closest to The answer, typically, was casino advantage the casino maintained "a house advantage.

Given that products offered by casinos are games, managers must understand why the games provide the expected revenues. In the gaming industry, nothing plays a more important role than mathematics. Mathematics should also overcome the dangers of superstitions. This web page owner of a major Las Vegas strip casino once experienced a streak of losing substantial amounts of money to a few "high rollers.

Casino advantage solution was simple. He spent the evening spreading salt throughout the casino to ward off the bad spirits. Before attributing this example to the idiosyncrasies of one owner, his are atypical only in their extreme. Superstition has long been a part of gambling - from both sides of the table. Superstitions can lead to irrational decisions that may hurt casino profits.

For example, believing that a particular dealer is unlucky against a particular winning player may lead to a decision to change dealers. As many, if not most, players are superstitious. At best, he may resent that the casino is trying to change his luck. At worst, the player may feel the new dealer is skilled in methods to "cool" the game. Perhaps he is even familiar with stories of old please click for source casino advantage employed dealers to cheat "lucky" players.

Understanding the mathematics of a game also is important for the casino operator to ensure that the reasonable expectations of the players are met. For most persons, gambling is entertainment. It provides an outlet for adult play. As such, persons have the opportunity for a pleasant diversion from ordinary life and casino advantage societal and personal pressures. Here an entertainment alternative, however, players may consider the value of the gambling source. For example, some people may have the option of either spending a hundred dollars during an evening by going to casino advantage professional basketball game or at a licensed casino.

If the house advantage is too strong and the person loses his money too quickly, he may not value that casino entertainment experience. On the other hand, if a casino can entertain him for an evening, and he enjoys a "complimentary" meal or drinks, he may want to repeat the experience, even over a professional basketball casino advantage. Likewise, new casino games themselves may succeed or fail based on player expectations. In recent years, casinos have debuted a variety of new games that attempt to casino advantage player interest and keep their attention.

Regardless of whether a game is fun or interesting to play, most often a player casino advantage not want to play games where his money is lost too quickly or where he has a exceptionally remote chance of returning home with winnings. Mathematics also plays an important part in meeting players' expectations as to the casino advantage consequences of his gambling casino advantage. If gambling involves rational decision-making, it would appear irrational to wager money where your opponent has a better chance of winning than you do.

Adam Smith suggested that all gambling, where the operator has an advantage, is irrational. He wrote "There is not, however, a more casino advantage proposition in mathematics than that the more tickets [in a lottery] you advertise upon, the more likely you are a loser.

Adventure upon all the tickets in the lottery, and you lose casino advantage certain; and the greater the number of your tickets, the nearer you approach to this certainty. Even where the house has an advantage, however, a gambler may be justified if the amount lost means little to him, but the potential gain would elevate him to a higher standing of living.

He could save or gamble this money. Even if he did this for years, casino advantage savings would not elevate his economic status to another level. While the odds of winning are remote, it may provide the only opportunity to move to a higher economic class. Since the casino industry is heavily regulated and casino advantage of the standards set forth by casino advantage bodies involve mathematically related issues, casino managers also should casino advantage the mathematical aspects relating to gaming regulation.

Gaming regulation is principally dedicated to assuring that the games offered casino advantage the casino are fair, honest, and that players get paid if they win. Fairness is often expressed in the regulations as either requiring a minimum payback to the player or, in more extreme cases, as dictating the actual rules of the games casino la vallée. Casino executives should understand the impact that rules changes have on the payback to players to assure they meet regulatory standards.

Equally important, casino executives should understand how government mandated rules would impact their gaming revenues. The player's chances of winning in a casino game and the rate at which he wins or loses money depends on the game, the rules in effect for that game, and for some games his level of skill.

The amount of money the player can expect to win or lose in the long run - if the bet is made over and over again - is called the player's wager expected value EVor expectation. When the casino advantage wager expectation is negative, he will lose money in casino advantage long run. When the wager expectation is viewed from the casino's perspective i.

For the roulette example, the house advantage is 5. The formal calculation is as follows: When this EV calculation is performed for a 1-unit amount, casino advantage negative of the casino advantage value is the house edge. Here are the calculations for bets on a single-number in double-zero and single-zero roulette.

Double-zero roulette single number bet: Single-zero roulette casino advantage number bet: The house advantage represents the long run percentage of the wagered money that will be retained by the casino. It is also called the house edge, the "odds" i. Regardless of the method used to compute it, the house advantage represents the price to the player of playing the game.

Because this positive house edge exists for virtually all bets in a casino ignoring the poker room and sports book casino advantage a few professionals can make a livinggamblers are faced with an uphill and, in the long run, losing battle. There casino advantage some exceptions. Occasionally the casino will even offer a promotion that gives the casino advantage player a positive expectation.

These promotions are usually mistakes - sometimes casinos don't check the math - and are terminated once the casino realizes the player has the edge.

But by and large the player will lose money casino advantage the long run, and the house edge is a measure of how fast the money will be lost. The trick to intelligent casino gambling - at least from the mathematical expectation point of view - is to avoid the games and bets with the large house advantages. Some casino advantage games are pure chance - no amount of casino advantage or strategy can alter the odds. These continue reading include roulette, craps, baccarat, keno, the big-six wheel of fortune, and slot machines.

Of these, baccarat and craps offer the best odds, with house advantages of 1. Roulette and slots cost the player more - house advantages of 5. Games where an element of skill can affect the house advantage include blackjack, video poker, and the four popular poker-based table games: Caribbean Casino advantage poker, Let It Ride, Three Card poker, and Pai Gow poker.

Blackjack, the most popular casino advantage all table games, offers the skilled player some of the best odds in the casino. The house advantage varies slightly depending on the rules and number of decks, but a player using basic strategy faces little or no disadvantage in a single-deck game and only a 0. Complete casino advantage strategy tables can be found in many books and many casino-hotel gift shops sell color-coded credit card size casino advantage. Rule variations favorable to the player include fewer decks, dealer stands on soft seventeen worth 0.

If the dealer hits soft seventeen it will cost you, casino advantage will any restrictions on when you can double down. Probability represents the long run ratio of of times an outcome occurs to of times experiment is conducted. Odds represent the long run ratio of of times an outcome does not occur to of times an outcome occurs. The true odds of an casino advantage represent the payoff that would make the bet on that event fair.

Confusion about Win Rate. There are all kinds of percentages in the world of gaming. Win percentage, theoretical win percentage, hold percentage, and house advantage come to mind.

Casino advantage

These numbers represent the average amount of all their wagers that players will casino advantage over the long term.

Remember, in gambling almost anything can happen in the short term. Concepts like house advantage and  Return to Player  are always calculated over the long term.

In effect, rules are the game. The rules can also help create a house advantage. House advantage is often achieved by setting payoff odds lower than the true odds of winning.

Roulette is a good example casino advantage this. In Casino advantage, roulette wheels have casino advantage numbered slots 1 to 36 and 0so the true odds of picking the correct number with a single bet are 36 to 1 36 loses for every one win. However, the payoff odds for picking the correct number are 35 to 1, just slightly less than the true odds. This difference between the true odds and the payoff odds results in a house advantage of 2.

American roulette wheels have 38 casino advantage Other common games in which the payoff odds are set lower than the true odds include mini-baccarat, blackjack, Pai Gow poker, let it ride, three card poker and Caribbean poker. It is the total amount wagered toxophore oranje casino uitbetaling ihn is exposed to the house advantage, not just the amount of money brought to the gambling game initially.

Many gamblers continually re-wager winnings, chips or credits, thereby increasing their total amount wagered and increasing the amount of money exposed to the house advantage. By far the most common form of gambling in casinos is slot machines.

Slots and VLTs are another form of gambling where the overall payoff odds are set lower than the true odds. The term gambling operators often use when referring to house advantage on slots and VLTs is casino advantage theoretical hold. The results of each and every play are random and independent of any other play; however, over the long term the overall results will drift toward the expected or theoretical hold.
