About Off The Number

Off The Number is where degens go to get information before placing a bet. It's a small independent site about the numbers: where a line opened, where it closed, and what happened against it. No sportsbook owns us, nobody here sells picks, and there are no sportsbook links on the site.

The name is the job. Getting a better number than the market settles on is the one edge that shows up over time. Everything here is built to help you see where the number is and how it got there.

Where the numbers come from

Current odds come from ten legal US sportsbooks (DraftKings, FanDuel, BetMGM, Caesars, theScore Bet, BetRivers, Fanatics, Hard Rock Bet, Bally Bet and betPARX) through The Odds API. We check every 5 minutes in the two hours before a game, every 10 to 15 minutes on game day, and less often for games further out. Pages update the numbers in place, so there is no need to refresh. The board shows the line most books are dealing with the middle price, plus the best price on each side and which book has it. No offshore books.

Schedules, scores and team stats come from ESPN's public data. Past closing lines come from ESPN's odds archive. "Open" is the game-week market open: the first consensus line once at least three of DraftKings, FanDuel, BetMGM, Caesars and theScore Bet have posted, taken from our own snapshots (for the NFL usually Sunday night or Monday after the prior week, for college football Sunday afternoon or evening). When we didn't catch that moment, the board says "First seen" with the day and time instead. Lines posted weeks early aren't used. Line charts and key-number crossings start at the open. If the multi-book feed ever goes down, pages fall back to DraftKings and say so.

We snapshot lines through the week and only keep a snapshot when a number changes. That is the movement chart on each game page.

How records are graded

Against the spread and over-under records are graded against the closing number. Pushes count as pushes and stay out of the percentage. Every number shows how many games it comes from and gets a plain call. "Likely real" means there are enough games that it probably isn't luck. "Could be luck" means a coin flip could have done the same thing. Under 20 games is "Small sample," always.

Billy's picks

Billy's picks are his own analysis. Each one is logged before kickoff with a server timestamp and a SHA-256 fingerprint, graded from final scores, and compared with the closing number. The full ledger, including anything rejected, is on the picks page.

Where to watch

Every game page ends with where it's on, and the watch section works out the cheapest way to stream your team's season.

How we make money

Right now, we don't. Down the road there may be affiliate links to streaming services or sportsbooks. If that happens, we'll label them, and they won't change a number on this site.
