How Does Sports Betting Work?

Sports betting is a popular pastime that allows individuals to engage in the excitement of predicting outcomes of various sporting events. At its core, sports betting involves placing money on a potential outcome of a particular sporting event in hopes of receiving a financial return if the prediction is correct.

This encompasses a wide range of sports and events, catering to the preferences of all types of fans and bettors.

Understanding how sports betting works begins with grasping the basics, such as various bet types, odds formats, and payout calculations. Online sports books enable bettors to establish accounts, fund them, and place wagers with just a few clicks. Among popular types of bets, one can find point spreads, which use plus and minus signs to denote how much a bet could potentially payout or how much one needs to place a bet to get a payout of $100.

Additionally, other odds formats like fractional and decimal are prevalent around the world, helping bettors gauge the potential return on their wagers based on their preferred format.

Navigating the world of sports betting can be complex, but by learning the basic principles, bettors can significantly enhance their understanding of this exciting pastime. As they gain experience, bettors may explore more advanced techniques and strategies to further increase their chances of success and potentially yield greater profits.

How Sports Betting Works

Sports betting involves placing a wager on the outcome of a sporting event. The simplest form of sports betting is predicting which team will win, but there are many other ways to bet on a specific team, outcome, or statistic. The two most common types of bets are spread and moneyline bets.

A moneyline bet focuses on picking the winner of the game outright. For instance, if you place a bet on Team A to win, you will receive a payout if Team A is victorious, regardless of the margin of victory. Moneyline odds are displayed in either a positive or negative format, which represents the amount you can win or the amount you need to wager to win a certain amount, respectively.

On the other hand, a spread bet considers not just the winner, but also the margin of victory. In this type of bet, a “spread” is assigned to each team, usually shown as a positive or negative number. For example, if Team B is favored to win by 4 points, their spread would be listed as -4. To win the bet, Team B must win the game by more than 4 points. Conversely, if you bet on Team A with a spread of +4, they can either win outright, or lose by fewer than 4 points, for your bet to be successful.

Another popular betting option is the Over/Under or total betting, which involves wagering on the combined points scored by both teams during a game. Sportsbooks set a predetermined number of total points, and bettors can choose whether they think the actual total points will be over or under that number.

When participating in sports betting, it is crucial to place bets with reputable sportsbooks, as that will help you better understand how online sports betting works. There are numerous strategies and systems that bettors can employ to increase their chances of winning, but it is essential to remember that sports betting should always be approached responsibly, with the understanding that there are no guarantees.

Types of Sports Bets

Sports betting offers a variety of bet types for enthusiasts to choose from. This section outlines six common bet types: Moneyline Bets, Point Spread Bets, Over/Under Bets, Prop Bets, Parlays, and Teasers.

Moneyline Bets

Moneyline bets are among the simplest forms of sports betting. With this type, bettors are wagering on which team or player will win a particular event or game. The odds for moneyline bets are based on the perceived strength of each competitor, with the underdog assigned higher potential payouts.

This bet type is common in individual sports like tennis, as well as team sports like basketball and soccer.

Point Spread Bets

Point spreads are a type of sports bet designed to level the playing field for unevenly matched teams. In this bet type, the favored team must win by a certain number of points, while the underdog must either win outright or lose by fewer points than the spread for them to win the bet.

You can find point spreads in sports like football and basketball, where scoring can be high and varied.

Over/Under Bets

Over/under bets, also known as totals, require bettors to predict whether the combined score of both teams in a game will be higher or lower than a predetermined number set by the sportsbook. These bets are popular in various sports, as they allow bettors to focus solely on the combined scoring without worrying about individual team performance or the final outcome of the game.

Prop Bets

Prop bets, short for proposition bets, are wagers placed on specific events or outcomes within a game. These bets can focus on individual player statistics—such as the number of goals scored by a soccer player or the number of touchdown passes thrown by a football quarterback—or on team performance, such as the first team to score in a game. Prop bets add excitement and variety to sports betting, as they cover a wide range of events not directly related to the outcome of a game.


A parlay bet is a single bet that combines multiple individual bets into one larger wager. In order for the parlay to be successful, all individual bets within the parlay must be correct—a single incorrect pick results in a lost parlay. Because of the increased difficulty of hitting every bet in the parlay, the potential payouts can be much higher than those of single bets. Parlays can involve multiple games, various bet types, and even different sports.


Teasers are a specific type of parlay bet involving point spreads or totals. In teasers, bettors have the option to adjust the point spreads or totals in their favor in exchange for reduced potential payouts. Teasers can be an attractive option for bettors looking for a little more control over their wagers, but the tradeoff for increased control is typically a smaller potential return on investment.

Teasers are commonly found in sports with regular point spreading, such as football and basketball.

Odds and Payouts

In sports betting, understanding the odds and payouts is essential for placing successful bets. This section will describe various types of odds, including decimal, fractional, and American odds.

Decimal Odds

Decimal odds are widely used in most parts of the world, particularly in Europe and Australia. These odds represent the total payout you will receive on a successful bet, including your original stake. To calculate your potential winnings, simply multiply your stake by the decimal odds. For example, if you bet $10 on a team with odds of 2.5, your potential payout would be $25 ($10 * 2.5). The larger the decimal odds, the higher the potential payout.

Fractional Odds

Fractional odds are popular in the United Kingdom and Ireland. They are represented as fractions, such as 3/1 or 5/2. The numerator (upper number) denotes the potential winnings while the denominator (lower number) represents the stake required to earn those winnings. To find your potential payout, divide the numerator by the denominator and then multiply by your stake, adding the original stake to get the total payout. For example, if you bet $10 with 3/1 odds, you would win $30 ($10 * 3/1) plus your original $10, resulting in a total payout of $40.

American Odds

American odds also known as moneyline odds, are commonly used in the United States. They are shown as either positive (+) or negative (-) numbers. Positive numbers denote how much profit you can make by placing a $100 bet, while negative numbers indicate how much you need to bet to make a $100 profit. For example, if a team has a +150 moneyline odd, a $100 bet on that team would yield a $150 profit. On the other hand, if a team has a -200 moneyline odd, you would need to bet $200 to make a $100 profit.

Understanding these different types of odds is crucial for making informed decisions in sports betting. By familiarizing yourself with decimal, fractional, and American odds, you can confidently place bets on your favorite sporting events and make the most of your sports betting experience.

Sports Betting Platforms

Online Sportsbooks

One popular platform for sports betting is online sportsbooks. These allow you to easily set up accounts, place bets, and access a wide range of sports and betting options. Online sportsbooks make it convenient for bettors who prefer to wager from the comfort of their homes or on the go. Examples of online sportsbooks include sites like DraftKings and FanDuel.

Mobile Applications

Mobile applications are another platform where bettors can engage in sports betting. These apps, specifically designed for smartphones and tablets, provide seamless access to betting odds, game schedules, and the latest sports news. Mobile apps also offer a user-friendly experience and the ability to place bets rapidly.

Some popular mobile applications for sports betting are Fox Bet and BetMGM.

Physical Sportsbooks

Lastly, physical sportsbooks are traditional in-person venues where bettors can wager on sports events. These establishments usually feature numerous large screen TVs, betting kiosks, and betting windows. You can find physical sportsbooks in cities with legalized sports betting, such as Las Vegas or Atlantic City.

While each platform has its merits, the choice ultimately depends on personal preferences and accessibility. Some bettors may appreciate the convenience and accessibility of online sportsbooks and mobile apps, while others may enjoy the social atmosphere and camaraderie found at physical sportsbooks.

Legality and Regulations

The legality of sports betting in the United States has changed significantly over the years. In the past, sports betting was largely prohibited, with a few exceptions like Nevada, where it was allowed due to the state’s long-standing gambling infrastructure. However, in 2018, the US Supreme Court issued a landmark decision permitting states to legalize and regulate sports betting within their borders.

Since this change, a growing number of states have jumped on the opportunity to legalize sports wagering. As of now, 30 states and the District of Columbia have legal and live sports betting legislations, allowing single-game sports betting. The legal landscape continues to evolve as more states consider legalizing this popular form of gambling.

Before 2018, the main hindrance to sports betting across the US was the Professional and Amateur Sports Protection Act (PASPA), which essentially gave Nevada a monopoly on single-game sports betting. This law had a significant financial impact on the industry and contributed to the rise of illegal sports betting.

One important federal law to be aware of is the Federal Wire Act of 1961, which was intended to prevent organized crime syndicates from engaging in illegal gambling activities over the phone. It prohibited the transmission of bets or betting information across state lines. While the Wire Act mainly targeted organized crime, it still has implications in today’s sports betting landscape.

Although the legality of sports betting varies from state to state, online sports betting is legal in 14 states as of 2020. The proliferation of online sports betting platforms has made it easier for people to access and participate in sports betting. It’s essential for bettors to stay up-to-date with the laws and regulations surrounding sports wagering in their specific location to ensure a safe and enjoyable betting experience.

To sum up, sports betting in the US has undergone a significant transformation in recent years, with more states joining the list of those that have legalized and regulated sports wagering. The current legal framework varies across the country, making it essential for bettors to stay informed about the legislation in their state.

Managing Risk and Bankroll

Managing risk and bankroll is an essential part of sports betting. A strong bankroll management strategy ensures that you can maximize your potential profits while minimizing potential losses. In sports betting, the margin for success can be extremely thin, so it’s critical to manage your funds effectively to enjoy a long-term profitable experience1.

One common bankroll management strategy is flat betting. This approach involves consistently betting the same amount on each game or match. For example, if you have a starting bankroll of $500, you might bet $10 on each game2. This ensures that you are not risking significant portions of your bankroll on a single bet, which could lead to reckless and impulsive betting decisions.

It’s also important to consider the “vig” or the fee that sportsbooks charge for placing a bet. The standard vig is -110, which means you must risk $110 to win $1003. By accounting for the vig in your betting decisions, you can better manage your risk and maintain control over your bankroll.

When managing your bankroll, it’s crucial to segregate your sports betting funds from your everyday finances. By keeping your betting money separate from your personal funds, you can better track your progress and avoid impulse betting decisions. This helps maintain financial discipline in your sports betting activities, ultimately contributing to a more enjoyable and successful betting experience.

In summary, effective bankroll management involves consistently setting aside a portion of your bankroll for each bet, accounting for the vig, and segregating your funds from your personal finances. By following these principles, you can maximize your potential profits, reduce the impact of losses, and enjoy a more satisfying sports betting experience.

Advanced Sports Betting Strategies

In the world of sports betting, experienced bettors often employ advanced strategies to gain an edge. These approaches are designed to help predict outcomes more accurately and maximize potential returns on investment. Let’s take a look at some of these advanced tactics.

One popular sports betting strategy is the Martingale System. This system involves doubling your bet after each loss, with the idea being that eventually, you’ll win and recover your previous losses. It’s essential, however, to have a substantial bankroll and a clear understanding of the odds to employ this strategy effectively.

Another advanced technique is hedging. Hedging involves placing bets on different outcomes of a single event to ensure a profit regardless of the result. For instance, you could bet on both teams in a soccer match, with the idea being that you’ll win one of the bets and minimize your losses on the other. This strategy is often utilized in live betting scenarios when the game’s momentum shifts, and new opportunities arise.

Betting the middle is another strategy to explore. This process involves placing wagers on both sides of a point spread or total with the hope that the final result falls between the two bets. By doing this, you can potentially win both bets or minimize your losses if only one of the bets is successful.

The zig-zag theory is frequently employed in playoff series betting, particularly in sports like NBA basketball and NHL hockey. The strategy is based on the idea that teams tend to bounce back after a loss and that momentum shifts from game to game. By betting on the losing team from the previous game, bettors try to take advantage of this trend.

Lastly, learning to identify value is essential. It’s not enough to rely on favorites or public sentiment when placing bets. Instead, you should study the market, the teams, and the matchups to identify instances when the odds provided by bookmakers do not accurately reflect the true likelihood of an outcome. By finding these value bets, you can potentially enjoy higher returns than simply following the crowd.

By mastering these advanced sports betting strategies, experienced bettors can increase their chances of success and enjoy a more sophisticated approach to wagering. Remember to stay disciplined, manage your bankroll wisely, and continually build your knowledge base to make informed decisions.

Frequently Asked Questions

What do the + and – symbols indicate in betting?

In sports betting, the + and – symbols represent the odds for a particular outcome. A ‘+’ sign indicates that the team or event is considered an underdog, meaning that the odds are against them to win. On the other hand, a ‘-‘ symbol signifies that a team or event is a favorite, meaning they’re more likely to win. For example, a +300 is an underdog where a $100 bet would return $300, whereas a -300 is a favorite, and it would take a $300 bet to win $100.

How do betting odds function?

Betting odds represent the probability of a specific event occurring. They’re used by bookmakers to determine the potential payout for each bet placed. For example, if you see an odds of +200, it means that for every $100 you bet, you could potentially win $200. Conversely, if you see an odds of -200, it means you would need to bet $200 to win $100.

What are some essential tips for beginners to place a bet?

  1. Start with a budget: Determine how much you’re willing to risk and stick to it. Remember that losing is a part of betting, and you should never bet more than you can afford to lose.
  2. Research and analyze: Study the teams, players, and event history. The more information you have, the better your chances of making accurate predictions.
  3. Compare odds: Different bookmakers offer different odds for the same event. Shopping around for the best odds increases your potential payout.
  4. Stick to a few sports: Focusing on specific sports allows you to become more knowledgeable and make better-informed decisions.
  5. Manage your bankroll: Diversify your bets across multiple events rather than putting all your money on one outcome.

Can you explain the concept of sports betting payout?

A sports betting payout refers to the amount a bettor stands to win if their bet is successful. Payout is calculated by multiplying the bet amount by the odds. For example, suppose you bet $10 at +150 odds. If your bet wins, your payout would be $25 ($10 x 1.5 + your original $10 bet).

What is the process of betting on sports legally online?
