Understanding the Plus (+) and Minus (-) in Sports Betting Odds

Welcome to the world of sports betting! If you’re new to this exciting form of gambling, it’s essential to grasp the basics of betting odds. The plus (+) and minus (-) symbols are fundamental components in understanding how to wager and what you could potentially win. Let’s dive into what these signs mean and how they can guide your betting strategy m88.

Favorites and Underdogs

In sports betting, teams or players are categorized as favorites or underdogs based on their perceived chances of winning a game or event.


The favorite is the team or individual that is expected to win. In betting odds, the favorite is always indicated with a minus (-) sign. This sign is followed by a number that represents the amount of money you need to bet to win $100.

Example: -200 Odds

If a team is listed at -200, you would need to bet $200 to win an additional $100 (plus your initial stake back).

Conversely, the underdog is the team or player that is considered less likely to win. The underdog’s odds come with a plus (+) sign, showing how much you would win if you bet $100.

Example: +200 Odds

With odds of +200 for an underdog, a successful $100 bet on them would yield $200 in winnings (plus your initial stake back).

Odds Fluctuations

Odds aren’t static; they can change for a variety of reasons, including betting patterns, player injuries, or other relevant news. Staying informed is crucial as these changes can affect the potential value of your bets.

Finding Value in Underdogs

While favorites are perceived as more likely to win, underdogs can offer greater value. Winning bets on underdogs typically pay out more than an equivalent bet on a favorite. The key is to find underdogs where you believe the odds are more favorable than the actual chance of winning.

Not All Favorites Are Equal

The number following the minus sign also indicates the size of the favorite. A -150 favorite is expected to win more often than a -110 favorite. Understanding this nuance can help in decision-making, especially when considering betting on favorites.

Promotional Bets and Boosted Odds

Promotions can dramatically shift odds, sometimes turning favorites into underdogs. Always check the terms of these offers to understand how they can impact your betting strategy.


Now that you understand the significance of the plus and minus signs in betting odds, you’re better equipped to make informed betting decisions. Remember, successful sports betting involves research, understanding value, and sometimes taking advantage of promotional offers. Good luck, and may your wagers be winners!
