In sports betting, you bet on whether a team will win or lose. You can place bets on individual teams, totals and props (props are specific bets that cover a wide range of events). Sportsbooks are businesses, so profit is one of their main goals. They make this money by taking a commission on each bet placed.

The plus (+) and minus (-) in sports betting refer to the point spread or betting odds. If you bet on the Cowboys -7, they have to win by more points than the Eagles for you to win your wager. Conversely, if you bet on the Packers +7, as long as they don’t lose by seven or more points, you will win your wager.

Some of the more popular bets are on the over/under. This bet predicts the combined total number of runs, goals or points scored in a game. The Over/Under is typically set at the sportsbook before a game begins and can be adjusted based on injuries, weather and other factors.

Many sports bettors use tracking apps to track their wagers, wins and losses. This allows them to keep track of their bankroll, and ensure that they are making wise decisions. It is also important to avoid raising your bets when you are winning, as this can quickly wipe out your profits. The key is to follow a profitable strategy and stick with it, regardless of how well you are doing.
