Read Every Betting Line on the Board

Sportsbook odds come in three formats — American, decimal, and fractional — and every one of them tells you the same thing in a different language.

How the Three Odds Formats Actually Work

American odds use a plus or minus number tied to a $100 base — a -150 favorite costs $150 to return $100 profit, while a +130 underdog returns $130 on a $100 stake. Decimal odds, common in international markets but available on some US sportsbooks, show your total return per dollar wagered including your stake, so 2.50 means $2.50 back on every

$1. Fractional odds like 5/2 tell you profit relative to stake directly. All three formats appear in our sportsbook, and you can often toggle between them inside your account settings without changing the underlying line.

HOW WE HANDLE ODDS

What Makes Our Sportsbook Lines Reliable

We source lines from established odds providers and display them without markup tricks. Here's what that means for you in practice.

Consistent Line Display Every odds format we show — American, decimal, fractional — pulls from the same underlying line. Switching formats in your account settings never changes the actual implied probability.
Transparent Juice The vig on any line is visible before you confirm a bet. We display both sides of a market so you can see the built-in margin without doing extra math.
Payout Calculator Built In Enter your stake in the bet slip and the potential payout updates instantly in whichever odds format you have selected — no separate app or spreadsheet needed.
Same-Game Parlay Clarity Same-game parlays on NFL and NBA markets show combined odds in American format by default, with a full leg-by-leg breakdown visible before you submit the ticket.

Key Sportsbook Terms Defined

Quick plain-language definitions for the odds and betting terms you'll see most often on our sportsbook lines.

What does 'moneyline' mean in sports betting?

A moneyline bet is a straight win/lose wager with no point spread. Odds show how much you risk or profit on a $100 basis using American plus/minus notation.

What is the 'vig' or 'juice' on a bet?

Vig is the sportsbook's built-in margin on a line. A -110 price on both sides of a spread means you risk $110 to win $100, and that $10 gap is the vig.

What does 'implied probability' mean?

Implied probability converts odds into a percentage chance of winning. A -200 favorite implies roughly a 67% win probability based on the price offered by the sportsbook.

What is a 'point spread' in football betting?

The point spread is a margin set by the sportsbook. You bet whether a team wins by more than that margin or keeps the final score within it, not just who wins outright.

What does 'over/under' or 'total' mean?

An over/under is a wager on the combined score of both teams. You pick whether the final total lands above or below the number the sportsbook posts before the game.

What are 'player props' in a sportsbook?

Player props are individual-performance markets — passing yards for an NFL quarterback, points scored by an NBA guard — priced in standard American odds on the bet slip.

Sportsbook Odds Questions We Hear Most

Real questions from people navigating our sportsbook lines for the first time — and straight answers.

Yes. Open your account settings, find the odds format preference, and choose the format you want. Every line on the board updates immediately without refreshing the page.

American odds — the plus and minus system — are the standard in the United States. Most NFL, NBA, MLB and college football lines here default to American format, though you can toggle to decimal.

For minus odds, divide 100 by the number and multiply by your stake to get profit. For plus odds, divide the number by 100 and multiply by your stake. The bet slip does this automatically.

Yes. A decimal price of 2.50 on a $40 wager returns $100 total — that's your $40 stake plus $60 profit. American odds show only profit, so the two formats express the same line differently.

When both sides are priced at -110, the vig is evenly split across the market. You're risking $110 to profit $100 on either side — that margin is how the sportsbook prices the spread.

Same-game parlay legs are correlated, so the combined odds are adjusted downward from a pure multiplication of each leg. The final price is shown in American format on the ticket before you confirm.
