How Each Odds Format Works on Our Sportsbook

American odds use a plus or minus sign anchored to a $100 base. A -150 favorite means you put up $150 to win $100; a +130 underdog returns $130 on a $100 wager. Decimal odds, common in college football same-game parlays on international books, fold your stake into the return — 2.50 means $25 back on a $10 bet, profit included. Fractional

odds like 5/2 tell you profit-to-stake in one fraction. Our sportsbook lets you toggle between all three formats inside your account settings, so the number on screen always matches the way you think about a line.

How We Keep Our Odds Accurate and Fair

Real-Time Line Updates

NFL point spreads and NBA moneylines update in real time as action moves. You always see the current number, not a stale figure from an earlier market state.

Consistent Payout Math

Switching from American to decimal format doesn't change what a line pays — it only changes how the number is displayed. The underlying payout calculation stays identical across all three formats.

Transparent Implied Probability

Every odds figure has an implied probability baked in. We show payout estimates on your bet slip so you can check the math before confirming a wager on any market.

Same Odds on Mobile and Desktop

Whether you're checking lines on your phone during a college football game or pulling up the sportsbook on desktop, the odds displayed are identical — no mobile-only spreads or different juice.

Sportsbook Odds Terms You Should Know

What does the minus sign mean in American odds?

The minus sign identifies the favorite. The number tells you how much you must wager to win $100. A -180 line requires an $180 bet to return $100 in profit.

What does a plus sign mean in American odds?

The plus sign marks the underdog. The number shows how much profit a $100 bet returns. A +160 line pays $160 in profit on a $100 wager if the bet wins.

What is implied probability in sports betting?

Implied probability converts an odds number into the percentage chance a sportsbook assigns to an outcome. A -200 favorite carries a 66.7% implied probability of winning.

What does 'juice' or 'vig' mean on a sportsbook line?

Juice, also called vig or vigorish, is the margin built into a line. Standard lines at -110 on both sides mean you pay slightly more than even odds — the house margin that keeps the book profitable.

What is a decimal odds format?

Decimal odds express total return per dollar staked, profit plus stake combined. Odds of 2.00 mean a $10 bet returns $20 total — $10 profit plus your original $10 stake back.

What does a point spread mean?

A point spread is a margin set by the sportsbook that the favorite must win by for a bet on them to pay out. It levels the betting field between mismatched NFL or college football teams.

Common Questions About Odds Formats at coinz

Yes. Head to your account settings and select your preferred format — American, decimal, or fractional. The choice updates across every sport and market, including NFL same-game parlays and player props, immediately.

They do. Decimal odds show total return, not just profit. Multiply your stake by the decimal number to get everything coming back — stake plus winnings — in one figure.

The format options are the same across sports. NFL point spreads, NBA moneylines, MLB run lines, and NHL puck lines all display in whatever format you've selected in account settings.

Multiply the decimal odds for each leg together, then multiply by your stake. A three-leg parlay at 1.80 × 2.10 × 1.95 gives a combined multiplier — your stake times that number is total return.

Lines move when significant money comes in on one side or when injury or lineup news breaks. The odds shown on your bet slip at confirmation are the ones that apply to your wager.

Availability depends on your state's laws and which states are currently eligible. Check your account or the sportsbook section directly to see whether wagering is available where you're located.
