How the spread works
A favorite listed at -6.5 must win by seven or more to cover. The underdog at +6.5 covers if they win outright or lose by six or fewer. The half-point (the "hook") prevents a tie. Both sides are usually priced around -110, meaning you risk $110 to win $100, with that extra $10 being the book's margin.
A worked example
Team A is -6.5 against Team B at +6.5. If Team A wins 27-20, that is a 7-point win, so -6.5 covers. If Team A wins 24-20, a 4-point win, then Team A fails to cover and the +6.5 underdog cashes even though they lost the game. The scoreboard and the spread result can disagree, which is the whole idea.
Reading spread movement
Spreads move as money comes in and as news breaks. When a line moves toward the less-bet side, sharper money is pushing it, a signal worth watching. Getting the best number matters most on spreads: a half-point can be the difference between a win, a push and a loss over a season.

Alternate lines
Extra spreads and totals at other numbers, like -6.5 instead of -3.5. Our prices for them come from a model, so check the number at the book.
Example: Main line -3.5 at -110; the alternate -6.5 might pay +170.
How our tools use it: A separate Alternate lines panel (DraftKings ladders), never merged into the ranked board. The fair comes from the main market's no-vig price through a normal model with a per-sport spread of outcomes. MLB and NHL 1.5 lines are not modelled. These are estimates from a model, not market prices.
Frequently asked questions
What does covering the spread mean?
A favorite covers by winning by more than the spread; an underdog covers by losing by less than the spread or winning outright.
Why are spreads set at half points?
The half-point (hook) removes the possibility of a tie, so every spread bet resolves as a clear win or loss rather than a push.
