Point Spread Betting
The point spread is American football's signature market — the handicap that turns a lopsided game into a near coin-flip. Here is how it works and why two numbers, 3 and 7, dominate it.
How the spread levels a game
Rather than just backing a winner, the spread is a bet on the margin. The favourite is given a points handicap — say -6.5 — and must win by more than that for a bet on them to pay. The underdog gets the same points the other way, at +6.5, and pays out if they win or lose by less than the spread. That handicap is what levels a mismatch, so a heavy favourite and a weak underdog become roughly even-money propositions. It is the same idea covered in the handicap betting guide, applied to the highest-scoring spread market in sport.
The key numbers: 3 and 7
American football scoring is not random — points come in threes (field goals) and sevens (touchdown plus extra point). That makes 3 and 7 the most common winning margins by far, the so-called key numbers. A spread of 3 is very different from 2.5 or 3.5, because so many games land exactly on a field goal. Smart spread bettors watch where a line sits relative to those numbers before they bet. The spread runs on every NFL game and is the headline market in the Super Bowl; the total is its companion bet. You bet at fixed odds, in rand, and a winning bet settles once the result is official.
Frequently asked questions
How does the point spread work?
It is a handicap on the margin. The favourite must win by more than the spread for a bet on them to pay, while the underdog can lose by less than the spread — or win outright — and still pay, which levels a one-sided game.
Why are 3 and 7 key numbers?
Because points come in field goals (3) and touchdowns with the extra point (7), those are the most common margins of victory. A spread set right on 3 or 7 is far more significant than one a half-point either side.
