Three Odds Formats, One Sportsbook Lobby

American odds are the default on 100ndb — a minus sign shows how much you risk to win $100, a plus sign shows what a $100 wager returns on top of your stake. Decimal odds fold your stake into the return figure, so 2.50 on an NFL game means a $10 bet returns $25 total. Fractional odds, more common in soccer markets,

express profit relative to stake: 5/2 means $5 profit for every $2 wagered. All three formats pull from the same live pricing engine, so the implied probability behind each number is identical no matter which display you choose in your account.

HOW WE PRICE LINES

Fair Odds Practices at 100ndb

Consistent Implied Probability Every format we display — American, decimal, fractional — reflects the same underlying implied probability. We don't adjust the math between formats; only the visual expression changes.
Live Pricing Engine NFL, NBA, MLB and college football lines update in real time from our pricing feed. A line you see on an NBA player prop or same-game parlay reflects current market movement, not a stale number.
Transparent Vig Display The overround built into each market is not hidden. When you compare the implied probabilities of both sides of a moneyline, the margin is visible in the math — we don't obscure it behind a format switch.
State-Eligible Access Only Sportsbook access on 100ndb depends on where state law permits. If your state isn't yet eligible, the sportsbook tab stays inactive in your account rather than showing unavailable lines.

Sportsbook Odds Terms, Plain and Simple

What does 'moneyline' mean in sports betting?

A moneyline bet is a straight pick on which side wins. No point spread involved. Odds are displayed in American format — minus for the favorite, plus for the underdog.

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

The vig is the sportsbook's built-in margin. It means both sides of a market don't add up to 100% implied probability — the gap is the house's cut on the action.

What does 'implied probability' mean?

Implied probability converts an odds number into a percentage chance. American odds of -110 imply roughly a 52.4% chance of winning, accounting for the vig baked into the line.

What is a 'point spread'?

A point spread handicaps the favored team by a set number of points. You're betting whether a team wins or loses by more or fewer points than that spread margin.

What is a 'same-game parlay'?

A same-game parlay combines multiple legs from a single game — like an NFL touchdown scorer and a team total — into one wager. All legs must hit for the parlay to pay out.

What are 'player props'?

Player props are bets tied to an individual athlete's performance — passing yards, points scored, strikeouts. They're priced separately from the game's main moneyline or spread.

Common Questions About Odds Formats

American odds are the default format on 100ndb because that's what most US bettors read fastest. You can switch to decimal or fractional any time inside your account settings — the change sticks across sessions.

For minus odds like -150, divide 100 by 150 then multiply by your stake to get profit. For plus odds like +200, multiply your stake by 2 to get profit. Your total return includes the original stake back.

Decimal odds include your stake in the return figure. American odds show only profit. So -110 in American format is roughly 1.91 in decimal — both represent the same bet, just expressed differently.

Yes. Switch your display to decimal in Settings > Odds Format and every NFL point spread, NBA moneyline and college football total will show in decimal. The underlying price stays identical to the American format.

Shortening odds mean the implied probability of that outcome is rising — usually because more money is coming in on one side, or because news like an injury or lineup change has moved the market.

No — fractional odds express profit-to-stake the same way regardless of the market type. Whether it's a player prop or a game total, 3/1 always means $3 profit for every $1 you wager on that line.
