Gambling

Though for many it is a form of recreation, gambling, like any behaviour 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 though they are losing. 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. Gambling may also refer to engaging in any high-risk behavior.

Gambling games are believed to predate recorded history, with gambling games recorded in virtually all of the ancient civilizations.

Legal aspects

Furthermore, gambling is either banned or heavily controlled (licensed) in many jurisdictions. Such regulation generally leads to gambling tourism and illegal gambling. The latter is 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.

One of the most widespread forms of gambling is betting on horse races. The most common types of horse race betting involve betting on races between thoroughbredss or between standardbredss.

Wagering may be conducted in 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 are:

• 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 and second
• 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.

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 differenet 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.

Sports betting

Betting on team sports is an important service industry in many countries. For example, football pools are played by millions of Britons every week.

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

In Canada and the United States the most popular sports bets are made:

• 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.
• 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

Staking systems

• 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

• Martingale- A system based on staking enough each time to recover losses from previous bet(s) until you get a winner. A guaranteed way to failure- only way it would work is if you have an unlimited bankroll, your bookamaker has no limit on the size of bets and you are immortal!
