Gambling

Gambling (or betting) is any behavior involving risking money or valuables (making a wager or placing a stake) on the outcome of a game, contest, or other event in which the outcome of that activity depends partially or totally upon chance or upon one's ability to do something.

Though many participate in gambling as a form of recreation or even as a means to earn a living, gambling, like any behavior which involves variation in brain chemistry, can become a psychologically addictive and harmful behavior in some people. Reinforcement phenomena may also make gamblers persist in gambling even after repeated losses. Because of the negative connotations of the word, casinos and race tracks often use the euphemism "gaming" to describe the recreational gambling activities they offer. The famous Russian writer Dostoevsky shows in his short story The Gambler the psychological implications of gambling and how it affects gamblers. He also associates gambling and the idea of " getting rich quick", suggesting that Russians may have a particular affinity for gambling. Dostoevsky shows the effect of betting money for the chance of gaining more in 19th-century Europe. The association between Russians and gambling has fed legends of the origins of Russian roulette.

Believers in the old saying about "never putting good money after bad money" offer this wisdom as a good way to keep gambling a pleasure and to stay away from gambling addiction. The saying suggests that after loosing wagered money one should stop gambling and just accept the loss, instead of keep betting and losing even more.

In extended usage, gambling may also refer to engaging in any high-risk behavior in which decisions occur based upon incomplete knowledge – for example, high-risk stock investments (see speculation), difficult and potentially costly ventures, or even personal relationships.

Gambling games may predate recorded history, with gambling games recorded in virtually all of the ancient civilizations. Islamic nations officially prohibit gambling; most other countries regulated it.

Legal aspects

Because of the generally negative religious view as well as various perceived social costs, most legal jurisdictions censure gambling to some extent. In particular, in many (most?) cases, the law does not recognise wagers as contracts and views any consequent losses as debts of honour, unenforceable by legal process. Thus organized crime often takes over the enforcement of large gambling debts, sometimes using violent methods. Because contracts of insurance have many features in common with wagers, legislation generally makes a distinction, typically defining any agreement in which either one of the parties has an interest in the outcome bet upon, beyond the specific financial terms, as a contract of insurance. Thus a bet on whether one's house will burn down becomes a contract of insurance, as one has an independent interest in the security of one's home.

Furthermore, many jurisdictions either ban or heavily control (license) gambling. Such regulation generally leads to gambling tourism and illegal gambling – the latter often controlled through organized crime. Such involvement frequently brings the activity under even more severe moral censure and leads to calls for greater regulation. Conversely, the close involvement in governments (through regulation and gambling taxation) has led to a close connection between many governments and gambling organisations, where legal gambling provides much government revenue. Note Monaco.

"Beatable" Casino Games

With proper strategy, a smart player can create a positive mathematical expectation.

"Unbeatable" Casino Games

All players must lose in the long run no matter what strategy chosen.

Fixed-odds gambling

Fixed-odds gambling and Parimutuel betting frequently occur at or on the following kinds of events:

In addition many bookmakers offer fixed odds on a number of non-sports related outcomes, e.g. the direction of various financial indices, whether snow will fall on Christmas Day, the winner of television competitions such as Big Brother, etc. Interactive trading exchanges also offer markets on these outcomes, with "shares" of results trading on an open market.

Other types of betting

One can also bet with another person that a statement is true or false, or that a specified event will happen (a "back bet") or will not happen (a "lay bet") within a specified time. This occurs in particular when two people have opposing but strongly-held views on truth or events. Not only do the parties hope to gain from the bet, they place the bet also to demonstrate how certain they are about the issue. Some means of determining the issue at stake must exist. Sometimes the amount bet remains nominal, demonstrating the outcome as one of principle rather than of financial importance.

List of notable wagers

Gambling on horse races

One of the most widespread forms of gambling involves betting on horse races, most commonly on races between thoroughbreds or between standardbreds.

Wagering may take place through parimutuel pools, or bookmakers may take bets personally. Parimutuel wagers pay off at prices determined by support in the wagering pools, while bookmakers pay off either at the odds offered at the time the bet was taken or at the median odds offered by track bookmakers at the time the race started.

In Canada and the United States, the most common types of bet on horse races include:

  • win– to succeed the bettor must pick the horse which wins the race.
  • place– the bettor must pick a horse which finishes either first or second.
  • show– the bettor must pick a horse which finishes first, second, or third.
  • exacta, perfecta, or exactor–the bettor must pick the two horses which finish first and second and specify which will finish first
  • quinella or quiniela– the bettor must pick the two horses which finish first and second, but need not specify which will finish first.
  • trifecta or triactor– the bettor must pick the three horses which finish first, second, and third and specify which will finish first, second and third.
  • double– the bettor must pick the winners of two successive races; most race tracks in Canada and the United States take double wagers on the first two races on the program (the daily double) and on the last two (the late double).
  • triple– the bettor must pick the winners of three successive races; many tracks offer rolling triples, or triples on any three successive races on the program.
  • sweep– the bettor must pick the winners of four or more successive races.

Win, place and show wagers class as straight bets, and the remaining wagers as exotic bets. Bettors usually make multiple wagers on exotic bets. A box consists of a multiple wager in which all possible combinations of a group of horses in the same race are bet. A key involves a multiple wager in which a single horse in one race is bet in one position with all possible combinations of other selected horses in a single race. A wheel consists of betting all horses in one race of a bet involving two or more races. For example a 1-all daily double wheel bets the 1-horse in the first race with every horse in the second.

In Canada and the United States exotic wagers are made on horses running at the same track on the same program. In the United Kingdom bookmakers offer exotic wagers on horses at different tracks. The most common is probably the Yankee, in which the bettor tries to pick the winner of four races. This bet also includes subsidiary wagers on smaller combinations of the chosen horses; for example, if only two of the four horses win, the bettor still collects for their double. A Trixie requires trying to pick three winners, and a Canadian or Super Yankee trying to pick five; these also include subsidiary bets. The nap is a term used to mark the best bet of the day.

A parlay (US) or accumulator (UK) is a series of bets in which the winnings from one race are bet on the next in order until either the bettor loses or the series is completed successfully.

(Similarly, greyhound racing offers a popular betting alternative to horse racing in many countries.)

Sports betting

Betting on team sports has become an important service industry in many countries. For example, millions of Britons play the football pools every week. At sports betting, players may beat the bank.

In Canada and the United States sports betting is usually illegal (Nevada offers full sports betting and the Canadian provinces offer Sport Select – government-run sports parlay betting). However, millions engage in it despite its illegality.

In Canada and the United States the most popular sports bets include:

  • against the spread; that is, the bettor wagers either that the favoured team will win by a specified number of points or that it will not. Betting the favourite is called giving the points and betting the underdog taking the points. See point spread.
  • against odds; the most popular types of bets against odds are simple bets that a team will win and over-under bets, which are bets on the total points, runs, or goals scored by both teams. In making an over-under bet, the bettor wagers that the total will be higher or lower than a total specified by the bookmaker.
  • against a combination of odds and spread

In sports betting a parlay involves a bet that two or more teams will win. In the United States one of the most common forms of sports betting is the parlay card, on which bettors wager on the outcomes of two or more games. If all their picks win, they collect. Most such betting occurs in workplaces.

Staking systems

Many staking systems have been formulated in an attempt to "beat the bookie" but it is still widely accepted that there is no staking system that can make an unprofitable system profitable over time. Widely-used systems include:

  • Fixed stakes – a traditional system of staking the same amount on each selection. This method is good for conservative punters if the stake is kept below 5% of the bank.
  • Fixed profits – the stakes vary based on the odds to ensure the same profit from each winning selection. This method is very good for conservative punters, although if the profitability of one's bets is independent of the odds the bettor is simply reducing his or her cash flow.
  • Due-column betting – A variation on fixed profits betting in which the bettor sets a target profit and then calculates a bet size that will make this profit, adding any losses to the target. For example, to make a target of $100 profit a bettor would wager $50 at odds of 2 to 1. If the bet loses, the target becomes $150. If the next bet is also at odds of 2 to 1, the wager therefore becomes $75. This type of wagering is ruinous in the long run.
  • Kelly (optimal) – fair odds (in the European/decimal format) need to be estimated by the punter and then the stake can be calculated using
Stake= (Odds/(Fair odds-1))/(Odds-1) Many times used with a divider (most commonly 4 or 8) depending on your bankroll (for betting)
This system was developed for baccarat but is widely recommended for horserace betting. In betting horseraces the stake is further adjusted to allow for inaccuracy in estimating fair odds. Computer simulations suggest that in betting horseraces Kelly betting increases losses during losing streaks, that it fails to demonstrate superiority over fixed stakes betting until large numbers of bets have been made (a drawback in horserace betting because the bettor usually has no reasonable expectation that any betting advantage he or she has will last over a long series of bets), and that inappropriate statistical analyses have exaggerated its profitability.
  • Martingale – A system based on staking enough each time to recover losses from previous bet(s) until you get a winner. The Martingale guarantees failure – it would only work if the bettor has an unlimited bankroll, the bookmaker has no limit on the size of bets and both are immortal!
