All relative events must be completed within the same day/session as listed in conjunction with the offer. Should this not be the case, bets placed on the offer will be fully refunded except for those offers whose outcomes were decided prior to the abandonment and could not possibly be changed regardless of future events, which will be settled according to the decided outcome.
The last types of bets that you should be aware of when betting on the NBA are proposition bets. A prop bet is a wager in which you bet on whether or not something is going to happen in a particular game. For example, will a certain player make more than four 3-pointers in a game? Which team will score first? Which team will win the opening tip-off? Will a certain team shoot over X % from the field? All of these are examples of prop bets that you can make on a particular NBA game.
Spread betting has moved outside the ambit of sport and financial markets (that is, those dealing solely with share, bonds and derivatives), to cover a wide range of markets, such as house prices. By paying attention to the external factors, such as weather and time of day, those who are betting using a point spread can be better prepared when it comes to obtaining a favorable outcome. Additionally, by avoiding the favourite-longshot bias, where the expected returns on bets placed at shorter odds exceed that of bets placed at the longer odds, and not betting with one’s favorite team, but rather with the team that has been shown to be better when playing in a specific weather condition and time of day, the possibility of arriving at a positive outcome is increased.
In North American sports betting many of these wagers would be classified as over-under (or, more commonly today, total) bets rather than spread bets. However, these are for one side or another of a total only, and do not increase the amount won or lost as the actual moves away from the bookmaker's prediction. Instead, over-under or total bets are handled much like point-spread bets on a team, with the usual 10/11 (4.55%) commission applied. Many Nevada sports books allow these bets in parlays, just like team point spread bets. This makes it possible to bet, for instance, team A and the over, and be paid if both team A "covers" the point spread and the total score is higher than the book's prediction. (Such parlays usually pay off at odds of 13:5 with no commission charge, just as a standard two-team parlay would.)
A money line, used in baseball and hockey, takes the place of a point spread. Money line betting is simply wagering on the contest based on a given price rather than a point spread. The team wagered on has to win the game outright, regardless of the score. The minus sign (e.g.-130) always indicates the favorite and the amount you must bet to win $100. The plus sign (e.g.+120) always indicates the underdog and the amount you win for every $100 bet. Using this example, therefore, you would bet $130 to win $100 on the favorite, while for the underdog you would bet $100 to win $120.
The team that has the minus sign, which is the favorite, has points deducted from its final score, while the dog, with the plus sign, has points added. The favorite must beat the spread, which means they have to win by more than the negative number to pay off. The underdog pays off in two instances—if they win outright or if they lose by less than the spread.
If you've never set foot in an actual sportsbook before or logged into an online sportsbook, the chances of you getting overwhelmed when you actually do is very high. In an actual Las Vegas sportsbook, there is typically a lot of commotion and the odds and lines are displayed on a massive digital board for everyone to see. When a novice sports bettor looks at the massive digital signage, they will see a bunch of numbers, both positive and negative, some two digits, some three digits. They also won't have a clue what any of it means. The same can be said for the online sportsbooks. It looks like a massive spreadsheet with negative and positive numbers beside each teams' name.
Sports betting has been around since 1000 B.C in China, where betting on animal fights was commonplace. In ancient Rome, one could wager on the Gladiatorial games. The idea of betting on sports is as old as organized sport itself. But up until the 1940s, bettors were fairly limited in what kind of bets they could make. The standard system of odds would allow bets on, for example, the 3-1 odds that the Steelers would beat the Browns.
