As the name suggests, American Odds are largely popular with sportsbooks here in the United States. American sports gambling odds work differently for favorites and underdogs, and are sometimes called Moneyline Odds.
American odds for betting on a favourite work by showing how much money you may need to risk to be able to win $100. Let’s illustrate that idea with a few soccer odds…
The Miami Dolphins are -110 to win Sunday’s game
Putting a successful $110 bet on them yields $100 winnings
In addition you get you first $110 back
Complete payout = 210
Things are a little different when gambling on an underdog, in that the positive number shows just how much you’ll win should you gamble $100. You may notice that this is similar to’odds-on’ bets in UK markets.
The Buffalo Bills have odds of +240 this Sunday
Putting a successful $100 wager will yield $240 winnings
You get your bet back
Complete payout = $340
If you see the letters PK alongside the odds offered on a match, it usually means that there is no preferred and you should”pick” the winner of the match without the need to be concerned about any point spread.
