LINE ACCURACY SIGNALS

Why You Can Rely on Our Odds Displays

Every line on our sportsbook is sourced and displayed consistently across formats. We do not alter the underlying probability when you switch display modes — the implied chance stays the same whether you're looking at -200 American, 1.50 decimal, or 1/2 fractional. Our markets include NFL point spreads, NBA totals, MLB moneylines, and college football same-game parlays, all presented with the format controls your account setting holds.

Format Consistency Switching between American, decimal, and fractional formats never changes the underlying implied probability — only the display notation changes, keeping your read accurate.
Live Market Accuracy Odds on NFL spreads, NBA player props, and MLB Baseball Live Betting Rules update in real time, so the number you see before you confirm is the number your wager locks in.
Same-Game Parlay Transparency Each leg of a same-game parlay shows its individual odds in your chosen format, and the combined payout is calculated and displayed before you submit the slip.
State-by-State Eligibility Access depends on local law and eligible states. We show you which markets are open in your state after you verify your account — no guesswork on availability.
prizepicks How Each Odds Format Works on Our Sportsbook

How Each Odds Format Works on Our Sportsbook

American odds use a plus or minus sign anchored to a $100 baseline. A -150 line means you need to risk $150 to return $100 in profit; a +130 line pays $130 profit on a $100 stake. Decimal odds — common on MLB Baseball Live Betting Rules and international soccer markets — multiply your total stake by the number shown, so 2.50

returns $2.50 for every dollar wagered. Fractional odds like 5/2 express profit over stake directly. We surface whichever format fits the market you're looking at, and you can switch your display preference inside your account settings at any time.

Sportsbook Odds Terms Defined

These are the terms you'll run into most often when reading lines on our sportsbook. Each definition is written the way a sharp bettor actually uses the term — short, plain, and checkable against any line you see.

What does moneyline mean in sports betting?

A moneyline is a straight-up bet on which side wins. No point spread involved. Positive numbers show underdog profit on a $100 stake; negative numbers show what you risk to win $100.

What is implied probability in odds?

Implied probability converts an odds number into a percentage chance of winning. A -200 American line implies roughly a 67% chance; a +200 line implies about 33%. It drives every odds format.

What does the point spread mean?

The point spread is the margin a favorite must win by for a spread bet to pay. A -6.5 NFL spread means the favorite must win by at least seven points; a +6.5 means the underdog can lose by six and still cover.

What are decimal odds?

Decimal odds express total return per dollar wagered, including your original stake. Odds of 2.00 double your money; 1.50 returns $1.50 for every $1 you put in. Common on soccer and international markets.

What does over/under (total) mean?

An over/under, or total, is a line set on the combined score of both teams. You bet whether the actual total will be higher or lower than the number the sportsbook posts.

What is vig or juice in sportsbook odds?

Vig — short for vigorish, also called juice — is the sportsbook's margin built into a line. It's why a standard spread bet is priced at -110 on both sides rather than even money.

Common Questions About Sportsbook Odds Formats

These are the questions we hear most often from people in New York and across eligible states who are getting comfortable reading sportsbook lines for the first time — or switching from one odds format to another.

Open your account settings, find the Odds Format preference, and select Decimal or Fractional. The change applies immediately across every open market on your screen, including live NFL spreads and NBA props.

No. The underlying line and implied probability stay identical. Only the notation changes. A -110 American line becomes 1.91 in decimal — same market, same math, different display for your preference.

Divide the odds number by 100, then multiply by your stake. A +250 line on a $40 wager returns $100 in profit — $40 times 2.5 — plus your original $40 stake back if the bet wins.

Your account display is set to one format at a time, so all legs in a same-game parlay show in the same format. The combined payout calculation is shown before you lock in the slip, regardless of which format you use.

That -110 pricing on each side of a spread is the vig — the sportsbook margin. Betting $110 to win $100 on both sides creates a built-in edge. When the line shifts, one side may move to -115 or -105.

Fractional odds appear most often on futures and certain international markets we carry. For NFL point spreads, NBA totals, and MLB moneylines, American odds are the default format most US bettors prefer.
