The most important thing to know about betting on sports is that it’s fun. And it’s always been fun.
Well before the legalization of sports betting in 2018, which set off a boom in the United States ($13 billion bet legally in 2019), sports fans enjoyed gambling on their favorite events and teams.
While sports betting is quickly becoming a piece of mainstream sports culture, people new to it should still have that one key objective before placing their first bet: have fun.
How does sports betting work?
There are thousands of sports betting options out there, but the basic premise behind it all is simply predicting that something will happen during a game or event and risking money on the chances of that occurring.
Sportsbooks will set odds on these occurrences based on their probability of happening, allowing you to bet on the side you think will win with the sportsbook essentially taking the opposite of that opinion.
If something has a high probability of occurring, it has a lower risk and won’t pay out as much as something with a lower probability and greater risk. The greater the risk the bigger the reward but… the greater the risk.
Most sports betting options offer two sides, such as team vs. team or Yes vs. No. However, some bets can have multiple options to wager on, such as picking which team will win the championship before the season begins.
Favorites & Underdogs
Two of the most common sports betting terms are favorite and underdog, which are often the two sides to a bet that you can wager on.
The favorite is the one side, team, or outcome that has the higher probability of winning or happening. Due to the lower risk, the return from betting on the favorite is smaller.
The underdog has a lower probability of winning. Due to the higher risk, the return from betting on the underdog is bigger.
If both sides have the same chances of winning, then the odds can be even for both and is often referred to as a pick or pick’em.
Types of bets
As we mentioned, while the premise of sports betting is simple – betting on one outcome or another – there are thousands of ways to bet on sports. These are the most common types of bets:
Spread bets, or point spreads, are used to make uneven games even. A point spread is assigned to a game based on the expected difference in the final score or result, and bettors must decide how much stronger one team is than the other.
Oddsmakers set a handicap between the two sides, forcing the favorite to win by a certain number of points (also known as cover the spread) in order to win the bet while allowing the underdog to win outright or lose by a certain number and still win the bet.
The point spread favorite will have a negative (-) value to its spread while the underdog will have a positive (+) value to its spread. If a game is too close to set a spread and both sides are perceived as even, the game will be deemed a pick or pick’em and you simply select which side will win outright.
Moneyline bets are the most basic type of sports wager: simply pick the winner. Moneylines are based on the implied probability of a result, such as one team beating another.
There are no spreads or handicaps involved to even the game, so a moneyline reflects the probability of the result, with low-risk moneylines (favorites) paying smaller returns and higher-risk moneylines (underdogs) paying bigger returns.
Moneyline favorites are indicated by a negative value (-) next to their odds and moneyline underdogs are indicated by a positive value (+) next to their odds.
Over/Under bets or totals are formulated from the projected total amount of points, runs or goals scored by both sides in a game.
Oddsmakers will assign a total to a game and bettors can choose whether the actual final score will go Over or Under that projected total. If a total is set at 50 points, a bet on the Over would need 51 or more combined points to win while a bet on the Under would need 49 or fewer combined points to win.
If the final score produces exactly the same amount of points as the Over/Under total, it’s graded a push and bets are returned.
Parlay bets are a combination of two or more bets tied together for a larger potential payout. However, for the parlay bet to win, all bets involved must be correct.
The more bets added to a parlay, the greater the risk and the bigger the potential return. But, even if only one of the bets involved in the parlay is wrong, the entire parlay is graded as a loss.
Parlays can involve multiple types of bets, including point spreads, moneylines and Over/Under totals. If you're trying to decide on what bets to parlay and want an idea what kind of payout it will yield, try using our parlay calculator.
What does -110 mean?
In sports betting, -110 means that for every $1 a bettor wants to win, they must risk $1.10. If a bettor wanted to win $100 on -110 odds, they would need to risk $110.
This odds format is known as American Odds and is most commonly used in North American sportsbooks and casinos. The -110 odds are commonly used with point spreads, with both sides of the spread listed at -110, also known as flat.
The negative value (-) before the American Odds indicates that the bettor must risk more than the return. If the American Odds have a positive value (+) before them, then the bettor can return more than the risk. At +110, a bettor could win $1.10 for every $1 wagered. There are other types of odds formats available, such as decimal or fraction, and if you'd like to see how American Odds translate into those formats, use our odds converter.

Other areas don’t allow for online sports betting or offer mobile sports betting sites linked to retail sportsbooks and casinos, which require deposits and withdraws in person.
Depositing into an online sportsbook is very quick and simple, with most accepting major credit cards, traditional and electronic bank transfers, as well as popular transfer methods like PayPal. Withdrawing winnings is just as simple, with funds returned through those common banking methods.
Best online sportsbooks

How to bet on sports in Vegas
Betting on sports in Las Vegas is one of the best experiences a sports fan can have outside of being in the stands. Most casinos offer incredible viewing experiences, with giant TV screens, lounge seating and multiple food and drink options.
Placing an in-person bet at a Las Vegas sportsbook requires you to know the ID or rotation numbers assigned to a particular game, with each side having a dedicated number. You tell the sportsbook ticket writer the rotation number, type of bet and size of wager, and they will give you a paper ticket for that bet that will be redeemed for money should it win.
Sports betting tips
There are endless strategies out there, but if you’re just dipping toes in the sports betting pool for the first time these are some basic sports tips to keep in mind:
- Be selective: You don’t need to bet every single game. The best bettors rank their potential picks in terms of confidence and from there decide which ones are worth the wager. One of the rare edges bettors have versus the sportsbook is that bookies must set odds for every game. Bettors, however, can pick and choose which bets they want to place.
- Home/Away: Where the game is being played can have a big impact on the outcome. Some teams perform better in their own venue and some struggle away from home. Home field or home court is something that oddsmakers work into the point spread and moneyline odds for host teams.
- Line moves: Sports betting odds are constantly adjusting to the action coming in at the sportsbook as well as other factors like injuries or weather. Getting the best odds for your opinion is vital to having success in sports betting and that means timing when you place your bet, either betting before or after the line moves.
- Injuries/Weather: Injuries to key players and multiple positions can impact the outcome of the game. Bettors must keep a close eye on any notable injuries that could affect their wagers. Weather is another factor to consider when betting on outdoor sports, like baseball and football. Rain, snow and wind can all influence the outcome.
- Money management: Depending on how much money you have set aside for sports betting, you will want to dedicate a certain bet size to each wager as to not deplete your bankroll with one bad day of wagering. Some suggest risking between 1 and 5 percent of your bankroll on each bet, depending on your confidence in the play. If you have $100 for a bankroll, you should keep your individual bets between $1 and $5.
- Betting trends: Tread lightly when it comes to betting trends. There’s a surplus of betting trends out there for just about every side of a wager. The best betting trends are built over the long term and have a narrative or reason to support their results. Beware banking on sporadic short-term betting trends built on small sample sizes.
- Know when to stop: One of the best tips for new sports bettors is knowing when to stop. There’s a temptation to bet more to make up for past losses, also known as chasing your bets when you have a bad day. Emotionally-charged wagers aren’t always smart wagers, so it’s best to step back, regroup, and shift focus to properly researching tomorrow’s games.
Sports betting FAQs
Which sport is the easiest to bet on?
While betting on any sport is a challenge, there can be more value in researching and betting on smaller-profile sports and leagues simply because not as much is known about them by both oddsmakers and the betting public.
Can you lose money on a winning bet?
Not normally. However, when betting on odds like moneylines you have to be careful of playing big moneyline favorites, as they do not return as much as you risk. You could theoretically win three-of-five bets but if those included some big moneyline favorites, you could lose money despite a winning record for your bets.
