Game Lines
Moneylines, spreads, totals, team totals and alternates priced against the market's fair line.
What it does
Game Lines is the +EV screen set to game markets: moneylines, spreads, totals, team totals and every alternate spread and total the books post. Each price at your books is compared with a fair price built from the other books, with the vig removed, and ranked by EV.
Exchanges and prediction markets are where game lines get interesting. A ProphetX price of +120 is +117.6 after the 2% commission on net winnings; a Polymarket contract at 45¢ (+122 on its face) is about +114 after its fee. Game Lines ranks those venues on that net price, so an edge you see is an edge after fees.
The fair price for an alternate spread or total comes from a fair ladder fitted across every book's main and alternate points. Rows priced that way are tagged MODELLED.
Who it's for
- Side and total bettors who shop several books.
- Kalshi, Polymarket, Novig and ProphetX users who want fee-adjusted prices compared with the sportsbooks.
- Alt-line bettors looking for a mispriced point, not just a mispriced main line.
- Anyone checking whether the -110 they're about to take is really the best price.
Coverage
The collector is built for four groups of books. Which of them quote a given game depends on what each book posts, so a column can be empty.
| Group | Books | How we use them |
|---|---|---|
| Regulated US sportsbooks | DraftKings, FanDuel, BetMGM, Caesars, Fanatics, theScore / ESPN BET, BetRivers, Hard Rock, Bally Bet, betPARX | Priced and used in the market consensus. Not available in Georgia. |
| Usable from Georgia | Fliff and Rebet (sweepstakes), plus offshore books | Sweepstakes books are priced like any book. Offshore books are shown for price comparison only: never linked or promoted. |
| Exchanges, prediction markets and sharp references | Kalshi, Polymarket, Novig, ProphetX, BetOpenly, Pinnacle, Betfair Exchange, Matchbook, Smarkets, Marathonbet | Exchanges and prediction markets are shown at your net price after the venue's published fees. Pinnacle and the exchanges anchor the Sharp preset. |
| Pick'em apps | PrizePicks, Underdog, DK Pick6, Dabble | Lines only. A pick'em line is never treated as odds; its price comes from the app's payout table. |
Sports the collector is built for: NFL, college football, CFL, NBA, WNBA, college basketball, NHL, MLB, KBO, NPB and soccer (Premier League, MLS, La Liga, Bundesliga, Serie A, Ligue 1, Champions League). What you see on a given day depends on what is in season and what the books have posted.
Markets: moneyline (1X2 regulation for soccer), spread, total, team totals and their alternates.
Pregame only. There are no live odds anywhere on the site, and a game drops off every tool at its start time. Refresh speeds up near the start: game lines every minute inside 2 hours, every 5 minutes from 2 to 12 hours, every 15 minutes from 12 to 36 hours and every 3 hours beyond; props every 5, 15 and 60 minutes in the first three windows. A credit budget guard slows the far windows first if credits run low. The ● Live · 12s badge in the top bar shows the true age of the newest collector run and turns amber (Delayed) when it is older than it should be.
What to check before you bet
- Whether the fair is EXACT LINE or MODELLED.
- Which books back the fair. A Required book (for example Pinnacle) can be set in Filters.
- Exchange depth. The net price is right, but the size behind it can be small.
- Key numbers on football spreads. A half point through 3 or 7 is worth more than one through 5.
- The price at the book before you bet.
How to use it
- Open Game Lines and pick the book or books you can bet at.
- Choose a league and market from the top bar, or leave it on all markets.
- Set the devig method and preset in Filters if you don't want the defaults.
- Open a row to see every book's price, the fair ladder and the math.
