How Each Odds Format Works on Our Sportsbook

Three formats live on our sportsbook: American, decimal, and fractional. American odds are the default for US bettors — a negative like -110 means you stake that amount to profit $100, while a positive like +150 returns $150 profit on a $100 wager. Decimal odds multiply your full stake by the displayed number: 2.50 on a $20 bet returns $50 total. Fractional

odds, popular in horse racing, show profit relative to stake — 5/2 returns five units of profit for every two staked. All three express the same underlying price; the format is cosmetic. Switch between them any time in your account settings, whether you're logged in from Charlotte or calling the game from your couch.

How We Keep Our Odds Honest and Readable

Accurate, transparent lines are what we're accountable to. Our odds feed from established real-time data sources, and we apply consistent vig across comparable markets — the price you see on an NFL spread reflects genuine market movement rather than a padded house margin. Every line update is logged, so if a price shifts before your bet confirms, the settled slip reflects the odds you accepted at the moment of placement. Access to our sportsbook depends on state law and eligible states.

Market Data Sourcing

Our odds pull from real-time sports data feeds, so line movements on NFL spreads or NBA totals reflect genuine market activity — not arbitrary adjustments made after the fact.

Vig Transparency

The juice on each market is visible in the odds themselves, not hidden. You can compare both sides of any spread and see the built-in margin clearly before you commit a wager.

Format Parity

American, decimal, and fractional formats convert from the same underlying price, verified on every market refresh. Switching formats never changes your actual payout — the math stays the same.

Settled Bet Records

Every settled bet shows an itemized payout record in your account history, including the odds at time of placement, making it straightforward to check any line was applied correctly.

Key Sportsbook Odds Terms Defined

These are the terms you'll see most when reading a betting slip, comparing lines across NFL spreads and NBA totals, or switching between odds formats in your account. Whether you're new to American moneyline pricing or trying to decode fractional odds on a horse racing market, each definition below is written in plain, jargon-free language.

What is moneyline?

A moneyline bet is a straight-up pick on who wins. Negative numbers identify the favorite; positive numbers identify the underdog. The figure sets the profit-to-stake ratio against a $100 base.

What is the vig or juice?

The vig is the margin built into the odds line. Standard spread markets often sit at -110 on both sides, meaning the sportsbook earns a small cut regardless of which side of the bet wins.

What does implied probability mean?

Implied probability converts an odds line into a percentage chance of an outcome — the break-even win rate baked into the price. It helps you compare your own read against the market.

What are decimal odds?

Decimal odds show total return per unit staked, stake included. Multiply your wager by the decimal — 2.50 returns two-and-a-half times your stake — so the profit calculation stays quick and straightforward.

What are fractional odds?

Fractional odds express profit relative to stake. A 5/1 line returns $5 profit for every $1 wagered, not counting your stake back. Horse racing markets in the US often default to this format.

What is a point spread?

A point spread assigns a handicap to level two mismatched teams. The favorite gives points (a -7 line must win by more than 7) while the underdog receives them, making both sides roughly equal to wager on.

Sportsbook Odds Formats — Common Questions

From decoding a -110 spread line for the first time to locking in a same-game parlay across an NBA double-header, odds format questions come up constantly. We've pulled the ones from our support queue that show up the most — about American moneyline reads, how vig works on a two-sided spread, and whether switching to decimal changes your actual payout. Direct answers, no jargon, so you can confirm the slip and get your bet in before the line moves.

American moneyline odds are the default on our sportsbook — they're what most US bettors use for NFL, NBA, and college football lines. Decimal or fractional can be set in your account display preferences.

A -150 line means you wager $150 to profit $100. It marks the outcome as the favorite — the larger the negative number, the heavier the market is weighing that side to win.

A +130 line pays $130 profit on a $100 bet. Positive numbers flag the underdog — the bigger the number, the longer the shot and the larger the return if that side comes through.

No — switching to decimal just changes the visual display. The underlying price is identical. Your parlay payout is calculated from the same market prices regardless of the format shown on screen.

That -110 on each side is the vig in action. The sportsbook earns a margin regardless of which side wins, which is why even closely matched spreads rarely settle at even money.

Yes — decimal format is especially useful for same-game parlays because you multiply each leg's decimal together to see the combined multiplier, making the total payout estimate easy to spot before confirming.
