Blackjack is a casino banking game. It is the most widely played casino banking game in the world. It uses decks of 52 cards and descends from a global family of casino banking games known as Twenty-One. This family of card games also includes the European games Vingt-et-Un and Pontoon, and the Russian game Ochko. Blackjack players do not compete against each other. The game is a comparing card game where each player competes against the dealer.
Games available in most casinos are commonly called casino games. In a casino game, the players gamble cash or casino chips on various possible random outcomes or combinations of outcomes. Casino games are also available in online casinos, where permitted by law. Casino games can also be played outside casino for entertainment purposes like in parties or in school competitions, some on machines that simulate gambling.
Craps is a dice game in which players bet on the outcomes of the roll of a pair of dice. Players can wager money against each other or against a bank. Because it requires little equipment, "street craps" can be played in informal settings. While shooting craps, players may use slang terminology to place bets and actions.
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.
Keno is a lottery-like gambling game often played at modern casinos, and also offered as a game in some lotteries.
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. In short, the word parimutuel implies tiered winnings/earnings.
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.
Fixed-odds betting is a form of wagering against odds offered by a bookmaker or an individual or on a bet exchange. It involves betting on an event in which there is no fluctuation on the payout. In Australia, the practice is usually known as "SP betting".
In probability theory, odds provide a measure of the likelihood of a particular outcome. They are calculated as the ratio of the number of events that produce that outcome to the number that do not. Odds are commonly used in gambling and statistics.
In a thought experiment proposed by the Italian probabilist Bruno de Finetti in order to justify Bayesian probability, an array of wagers is coherent precisely if it does not expose the wagerer to certain loss regardless of the outcomes of events on which they are wagering, even if their opponent makes the most judicious choices.
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 Ukrainian or Russian.
Sport Select is a group of sports betting games offered by Canada's lottery corporations. In Quebec, the program is known as Pari sportif; in Ontario and Atlantic Canada, it is known as Pro-Line while in British Columbia, it is known as Sports Action. However, the rules for the games are similar in all provinces. Initially created to offer betting primarily on the North American major professional sports leagues, Sport Select has expanded to offer betting on competitions such as the English Premier League and college sports.
Sports betting is the activity of predicting sports results and placing a wager on the outcome.
A progressive jackpot is a jackpot which increases each time the game is played but the jackpot is not won. When the progressive jackpot is won, the jackpot for the next play is reset to a predetermined value, and resumes increasing under the same rule.
In the United States, a sportsbook or a race and sports book is a place where a gambler can wager on various sports competitions, including golf, football, basketball, baseball, ice hockey, soccer, horse racing, greyhound racing, boxing, and mixed martial arts. The method of betting varies with the sport and the type of game. 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.
A parlay, accumulator, combo bet or multi is a single bet that links together two or more individual wagers and is dependent on all of those wagers winning together. The benefit of the parlay is that there are much higher pay-offs than placing each individual bet separately since the likelihood of hitting all of them at once is much less. If any of the bets in the parlay lose, the entire parlay loses. If any of the plays in the parlay ties, or "pushes", the parlay reverts to a lower number of teams with the odds reducing accordingly. In order to win a parlay, every wager within it must win.
A betting pool, syndicate, sports lottery, sweep, or office pool if done at work, is a form of gambling, specifically a variant of parimutuel betting influenced by lotteries, where gamblers pay a fixed price into a pool, and then make a selection on an outcome, usually related to sport. In an informal game, the vig is usually quite small or non-existent. The pool is evenly divided between those that have made the correct selection. There are no odds involved; each winner's payoff depends simply on the number of gamblers and the number of winners.
An each-way bet is a wager offered by bookmakers consisting of two separate bets: a win bet and a place bet. For the win part of the bet to give a return, the selection must win, or finish first, in the event. For the place part of the bet to give a return, the selection must either win or finish in one of the predetermined places for the event, such as first place or second place. The odds paid on the place part of the bet are usually a fraction of the win odds. The trade-off being that one has a greater chance of making one's bet in trade for getting less payoff for doing so. Examples are domestic football knockout competitions where the quoted place terms may be 1⁄2.
The Delaware Lottery is run by the government of Delaware. Its creation was authorized by the state legislature on May 31, 1974. Its "traditional" games include Play 3, Play 4, Multi-Win Lotto, Lucky For Life, Lotto America, Mega Millions, and Powerball. Delaware also offers Keno, sports betting, and video lottery.
A progressive parlay is a joint wager on multiple events, for example team sports or horse races. Generally a progressive parlay involves a joint wager on four to twelve separate events. Should all the selected bets win, the bettor receives a relatively large payout, because of the sizable odds against this happening. However, unlike a regular parlay, if some of the individual bets lose, but most win, the bettor still wins, although with a much smaller payout. Several sites use a schedule where the bettor can lose one bet on a 4-6 event progressive parlay, can lose up to two bets on a 7-9 event progressive parlay, and up to three bets on a 10-12 event progressive parlay.
