Gambling is the wagering of something of value on a random event with the intent of winning something else of value, where instances of strategy are discounted. Gambling thus requires three elements to be present: consideration, risk (chance), and a prize. The outcome of the wager is often immediate, such as a single roll of dice, a spin of a roulette wheel, or a horse crossing the finish line, but longer time frames are also common, allowing wagers on the outcome of a future sports contest or even an entire sports season.
Parimutuel betting or pool betting is a betting system in which all bets of a particular type are placed together in a pool; taxes and the "house-take" or "vigorish" are deducted, and payoff odds are calculated by sharing the pool among all winning bets. In some countries it is known as the tote after the totalisator, which calculates and displays bets already made.
Spread betting is any of various types of wagering on the outcome of an event where the pay-off is based on the accuracy of the wager, rather than a simple "win or lose" outcome, such as fixed-odds betting or parimutuel betting.
A Calcutta auction is an open auction held in conjunction with a golf tournament, horse race or similar contest with multiple entrants. It is popular in backgammon, the Melbourne Cup, and college basketball pools during March Madness. Culcutta auction is a sequential auction, where the bidding for each contestant begins in random order, with only one contestant being bid upon at any time. Accordingly, participants bid among themselves to "buy" each of the contestants, with each contestant being assigned to the highest bidder. The contestant will then pay out to the owner a predetermined proportion of the pool depending on how it performs in the tournament. While variations in payoff schedules exist, in an NCAA Basketball tournament the payoffs could be: 1 win - 0.25%, 2 wins - 2%, 3 wins - 4%, 4 wins - 8%, 5 wins - 16%, tournament winner with 6 wins - 32%.
A betting exchange is a marketplace for customers to bet on the outcome of discrete events. Betting exchanges offer the same opportunities to bet as a bookmaker with a few differences. Gamblers can buy and sell the outcome, and they can trade in real-time throughout the event, either to cut their losses or lock in profit. Bookmaker operators generate revenue by offering less efficient odds. Betting exchanges normally generate revenue by charging a small commission on winning bets.
Vigorish is the fee charged by a bookmaker for accepting a gambler's wager. In American English, it can also refer to the interest owed a loanshark in consideration for credit. The term came to English usage via Yiddish slang which was itself a loanword from Russian.
In the United Kingdom, the football pools, often referred to as "the pools", is a betting pool based on predicting the outcome of association football matches taking place in the coming week. The pools are typically cheap to enter, and may encourage gamblers to enter several bets.
A betting strategy is a structured approach to gambling, in the attempt to produce a profit. To be successful, the system must change the house edge into a player advantage — which is impossible for pure games of probability with fixed odds, akin to a perpetual motion machine. Betting systems are often predicated on statistical analysis.

In the US, the Professional and Amateur Sports Protection Act of 1992 allowed only Nevada, Oregon, Montana, and Delaware to legally wager on sports other than horse racing, greyhound racing, and jai alai; the law was ruled unconstitutional on May 14, 2018, freeing states to legalize sports betting at their discretion.

March Madness pools are a form of sports betting based on the annual NCAA Division I men's basketball tournament each spring in the United States. The popularity of this phenomenon is fostered by March Madness pools, or brackets. The tournament bracket can be completed online or printed out and completed by hand whereby the participant predicts the outcome of each game in the tournament. The bracket is to be completed before the tip of the first four games begin. His or her predictions are compared against others in the pool, and whoever has the best prognostication skills wins the contest. Various other bracket games exist including a board game whereby players draft teams.

Betting on horse racing or horse betting commonly occurs at many horse races. Modern horse betting started in Great Britain in the early 1600s during the reign of King James I. Gamblers can stake money on the final placement of the horses taking part in a race. Gambling on horses is, however, prohibited at some racetracks. For example, because of a law passed in 1951, betting is illegal in Springdale Race Course, home of the nationally renowned Toronto-Dominion Bank Carolina Cup and Colonial Cup Steeplechase in Camden, South Carolina.
