As you might guess, you’re mainly going to see American odds in American sportsbooks. The other two formats are much more prominent in Europe and Asia. If you’re betting online, most sportsbooks give you the ability to change all of the odds on the site into the format that you prefer. No format is different regarding payouts; it’s just a different way of presenting the information.
When betting the point spread, there is almost always a winner and a loser. However, in some instances sportsbook decide to put out a whole number such as -3 for bettors to bet on. If the final score ends with a differential of three points - no matter who wins - the bet is considered a "push" and all money is refunded to both sides since neither team covered the spread.
"Winning Margin" (aka Result Betting) is where it is possible to bet on the final result of a game or event and select the correct ‘band’ of points between the winning team and losing team. For example, if you think the Patriots will win, but the game will be close, pick the New England Patriots 1-6 Points Winning Margin (where the Patriots winning by 1, 2, 3, 4, 5, or 6 points results in a winning selection).
The "Total Points", also known as Goals or Runs, is a 2 selection odds based on the total number of points scored in a game or event by the competitors. The "Total" is set at a specific line with outcomes listed as either Over or Under the listed amount. As with Point Spread/Handicap betting, in those circumstances where the result of the game or event Total point scored is exactly equal to the betting line, then all bets on this offer will be declared void. “Totals” can also be set on any number of predefined occurrences (e.g. goals, points, corners, rebounds, penalty minutes, etc.).
Oftentimes you’ll see a point spread that has a half-point added to the number. Of course, there’s no such thing as half a point in a football game, so why do we so often see point spreads with a (.5) attached to the score? Sportsbooks do this to make sure there isn’t a chance of a push. Let’s take another look at our game from above with the half point added.
