## What is “+” and “-” in sports betting?

In addition to numbers and terms, there are signs in sports betting – “+” and “-“, which indicate the expectations of the specialists. They are added to odds and lines, and bettors need to be aware of their meanings to make the right decision.

### Plus and Minus in odds

Odds in bookmakers are divided into two types – one denotes the advantage of the favorite, and the other – the underdog’s gap.

For example, odds of (-200) indicate that we need to bet $200 to win $100. Bets with a “minus” target the favorite in the event. The more money we have to risk, the better the odds of taking the winning side.

Odds with a “+” sign are used when betting in favor of the underdog.

Example: if you notice a bet (+250), it follows that if you bet $100 – you will win $250.

Understanding the principles of Return On Investment (ROI) in sport bets will ensure higher rewards from the games.

### Bookmaker commissions

There is no betting company that offers maximum even odds for two-outcome events (-100 vs -100).

For example, the Phoenix Suns and Milwaukee Bucks are evenly matched teams whose NBA matchup is difficult to predict. Each team is expected to win at odds of -100. But in order to generate revenue from users’ bets, the gambling brand deducts a margin (vigorish) and equates the odds to -110. Thus, to win $100, it is necessary to risk $110 instead of $100.

## Plus and Minus on lines and markets

We’ve clarified the use of “+” and “-” in American odds, but these signs find application in some markets as well. A great example is the Asian handicap.

The minus sign gives an edge to the favourite. For example, a bet on AH (-3.5) is profitable if the selected team wins by a margin of 4 points. In the opposite case, AH (+3.5) will win if the underdog is successful or loses by a maximum of 3 points.

Asian Handicap and Asian Lines are available for bets on basketball, baseball, American football and other sports.
