If you’re just getting started with sports betting, it can be challenging to know where to begin. Even if you’re a regular bettor, it’s easy to get lost among the choices.
Sometimes, it’s best to keep it simple. There are three base options when we think of traditional sports bet types. The first two are moneyline and point spread, and the third is the totals, aka, the over/under bet.
Totals betting, or over/under betting, is the process of placing a wager on whether the combined score of the two teams will be over or under an amount of points that oddsmakers set in advance of a game.
It’s that easy. Sportsbooks will have the totals number set before a game begins, and bettors will have two choices: over or under. If the two teams’ combined score is higher than the number that oddsmakers have set, then bets on the “over” win. If the combined score is lower, it’s a win for the “under” bet.
There are options for markets at nearly all online sports betting sites, such as team totals or totals for a specific part of a game (quarters or halves). These are often categorized as props and aren’t conventional betting markets. For the sake of education, we are sticking to the full-game totals with the combined points of both teams.
There’s no better way to understand how a total bet works than by using an example. So, let’s take a look at the over/under set by DraftKings for betting on the Iowa Hawkeyes basketball game against North Carolina:
|North Carolina Over 158.5 (-109)|
|Iowa Hawkeyes Under 158.5 (-110)|
DraftKings Sportsbook set this over/under at 158.5 points. As is the case with point spreads, the total will be the same for each team. A bet on the over requires 159 points or more to secure a victory, while anything at 158 points or fewer will be a win for the under wager.
While the total is the same on both sides, we can see that the price that comes with each side (the “juice” or “vig,” as it is known) may vary from one to the other.
A bet on over 158.5 (-109) means you must risk $10.90 for every $10 in profit, $54.50 for every $50, or $109 for every $100. On the other side, a wager on under 158.5 (-110) means risking $110 for $100 in profit. Keep in mind that these prices are relative to the number 100, and you can easily do the math from there, depending on what you choose to risk.
NBA totals betting is not unlike our example that covered NCAA basketball. Take this example of the Chicago Bulls against the New York Knicks:
|Chicago Bulls Over 209 (-110)|
|New York Knicks Under 209 (-110)|
With the total at 209 points, a bet on the over requires 210 total points or more. However, a wager on the under is a win if the score adds up to 208 points or fewer. In the event the game ends up at exactly 209 points, the sportsbook will consider the bet a “push,” and it will return bettors’ original stakes on both sides.
The key difference when wagering on an NBA total than an NCAA total is that the over/under figure itself will be higher. This is because professional basketball teams tend to score more than college teams. There are several reasons for this, including that the NBA has a shorter shot clock and more playing time in each game.
A college basketball game consists of two 20-minute halves, while an NBA game is four 12-minute quarters for a total of 48 minutes. The shot clock for NCAA games (both men’s and women’s) is 30 seconds, while NBA games feature a 24-second shot clock, leading to more possessions and more points.
Wagering on NFL totals doesn’t differ much from basketball. In fact, the process is the same, and all the rules apply in much the same way. Take our example:
|Dallas Cowboys Over 53.5 (-115)|
|Kansas City Chiefs Under 53.5 (-105)|
If the Chiefs and Cowboys combine for 54 points or more, the over hits. At a -115 price, you would need to risk $115 to win $100. If the final score totals a combined 53 points or fewer, it’s a win for the under. At -105, it would be a risk of $105 for every $100 in profit.
The juice on this particular total is shaded a bit toward the over at -115, considering that most lines begin around -110.
There are several reasons for this type of line movement. It’s possible that both sides start at -110 and more action on the over pushed the line to -115. It’s also possible that oddsmakers saw more value in the over from the start and shaded the price in that direction, knowing the public may be keen on it.
Whatever the reason, the juice is a great reason to line shop at multiple sites and be sure to get the most advantageous line possible.
As we all know, baseball isn’t a sport that lights up the scoreboard the way basketball or football does, so totals betting in baseball is a bit different. Let’s look at an example using two popular teams among Iowa baseball fans:
|Kansas City Royals Over 9.5 (-102)|
|Minnesota Twins Under 9.5 (-120)|
Even though the total score of an MLB game is unlikely to match a football game, much less a basketball game, the process of wagering on the total and calculating the risk/reward is the same.
In this example, a wager on the Royals/Twins over 9.5 needs 10 or more runs to be a winner, whereas a bet on the under needs nine or fewer runs to win. At -102, winning $100 means risking $102. For the under, you would need to risk $120 to win $100.
With fewer runs in baseball than points in some other sports, each half-run matters plenty. It will take a lot of action to move the run total by a half-point because of this, so it’s quite common to see a wider variation in the juice when looking at baseball betting lines compared to other sports.
When it comes to wagering on totals in baseball, the starting pitchers and the weather are two things all you need to keep in mind.
Hockey is a sport where goals come at a serious premium, even more so than baseball runs on many occasions. Below is an example of a hockey total:
|Minnesota Wild Over 5.5 (-130)|
|Detroit Red Wings Under 5.5 (+105)|
Hockey totals usually hover between five and 6.5 goals, with 5.5 and six being the two most popular totals. Since each goal is so valuable, it is quite common for the juice on these totals to alter more than most other sports before a total will move by half a goal.
In our example, an over bet requires six goals to hit and will cost $130 for every $100 in profit. The under is plus-money, and a $100 wager will pay out $105 if there are five goals or fewer.
Hockey is also a sport where the losing team may pull its goaltender at the end of games, leaving an empty net for the team in the lead. It is common for an empty-net goal (or lack thereof) to play a serious role in whether a game goes over or under.
As is the case with point spread betting, there are markets at most online sportsbooks and mobile betting apps for alternate totals. This allows you to venture outside of the over/under set by oddsmakers and select nearly any total they want, within reason.
The sportsbook will modify the line, which will require you to risk more when buying points, runs or goals. At the same time, you can earn extra by selling them for a line that comes with a higher potential payout.
