How to Bet on the NFL

The NFL is the most heavily bet league in North America, and Canadian bettors now have full legal access to single-game wagering — from spreads and totals to player props and teasers. This guide breaks down the core bet types, the math that actually matters (hello, key numbers), and how to approach primetime slates like a sharp rather than a square.

First, the Canadian Context

Single-event sports betting has been legal across Canada since Bill C-218 amended the Criminal Code in August 2021. Before that, Canadians were limited to parlay-style “pro-line” tickets — you couldn’t bet a single game on its own. That’s changed nationwide.

Regulation, however, is provincial:

• Ontario runs an open, regulated market through iGaming Ontario and the AGCO (live since April 2022), where private operators like FanDuel, DraftKings and bet365 are licensed. See our Ontario betting hub for registered options.
• Other provinces generally offer single-game betting through provincial lottery platforms — PROLINE+ in Ontario, Sport Select in the West, Mise-o-jeu in Quebec.
• All wagers are placed and paid in Canadian dollars, most commonly funded via Interac e-Transfer.

Always use a legal, regulated operator for your province. Our betting sites comparison covers who’s licensed where.

Point Spreads: The Line Everyone Watches

The point spread handicaps the favourite so that betting is roughly balanced on both sides.

• The favourite is shown with a minus (e.g. −6.5); the underdog with a plus (+6.5).
• Favourite −6.5: must win by 7 or more to “cover.”
• Underdog +6.5: covers by winning outright or losing by 6 or fewer.
• Standard pricing sits around −110 per side — the “vig” or juice. You risk $110 to win $100.
• The half-point (the “hook”) prevents a push (a tie, which refunds your stake).

Example: Chiefs −6.5 vs. Broncos. If Kansas City wins 27–20, they win by 7 and cover the spread.

Totals (Over/Under)

A total is a bet on the combined points scored by both teams, regardless of who wins.

• A typical line might be set around 47.5 — you bet Over or Under.
• Also priced near −110 per side.
• Key drivers: offensive/defensive quality, pace, weather (wind and cold suppress totals), dome vs. outdoor venue, and injuries to skill-position players.

Whole-number totals (like 44) can push and refund; half-point totals cannot. Weather is the single most underrated factor here — a howling wind at a lakefront stadium in December can gut a passing game and, with it, the over.

Player and Game Props

Props are bets on specific outcomes within a game rather than the final result — and they’re where the NFL’s data-rich nature really shines.

• Player props: passing yards, rushing yards, receptions, receiving yards, and touchdowns. Most are over/under lines (e.g. a QB’s passing yards) or yes/no markets like an anytime touchdown scorer.
• Game/team props: first team to score, total team points, whether the game reaches overtime.
• Same-game parlays (SGPs): combine multiple legs from one game. Big potential payouts, but correlated legs are priced accordingly, and the house edge is steep.

Props generally carry wider vig than spreads and totals, so line shopping matters even more here. A half-yard difference on a receiving-yards line — or a materially better price on the same TD scorer across two books — adds up over a season.

Teasers: Moving the Line in Your Favour

A teaser lets you shift the spread or total in your favour across two or more games — in exchange for a lower payout because all legs must win.

• The classic is a 6-point, two-team teaser in the NFL, moving each spread 6 points your way.
• The math works best when you’re teasing through the key numbers 3 and 7 — the so-called “Wong teaser.”
• Ideal candidates: teasing a favourite from −7.5 to −1.5 (crossing both 7 and 3), or an underdog from +1.5 to +7.5 (crossing 3 and 7). These cross the two most common margins of victory.
• Teasing through “dead” numbers like 5 or 8 wastes value — you’re paying the same price for far less useful points.

Teasers are a tool, not a shortcut. Their edge comes entirely from disciplined use around key numbers.

Key Numbers: The Concept That Separates Sharps from Squares

Because NFL scoring clusters around field goals (3) and touchdowns (7), games are decided by certain margins far more often than others. This is the single most important idea in NFL betting.

• The two most important key numbers are 3 and 7. A disproportionate share of games land on exactly these margins.
• Secondary key numbers: 6, 10 and 14 (and to a lesser extent 4).
• Why it matters: grabbing an underdog at +3 instead of +2.5, or a favourite at −2.5 instead of −3, can be the entire difference between a win, a push and a loss. Moving across 3 is worth dramatically more than moving across a dead number like 5.

Practical takeaway: don’t just take the first line you see. Shop multiple books and prioritize the best number around 3 and 7. Over a full season, a half-point at the right spot is real money. Our betting guides dig deeper into line shopping.

Betting NFL Primetime

Primetime windows — Thursday Night, Sunday Night and Monday Night Football — are a different beast.

• Sharper, later lines: by kickoff, the market has digested a full week of information, so soft numbers are rarer than in an early Sunday slate.
• Public bias: big national broadcasts attract casual money on favourites and overs, which can inflate those prices — sometimes creating value on the other side.
• Thursday quirks: short-week games (especially for the road team) historically favour caution; fatigue and limited prep are real factors.
• Live betting shines in standalone primetime games — with only one game on, you can watch the full flow and hunt for in-game spots.

Building a Sensible NFL Approach

• Shop lines across multiple licensed books, especially around 3 and 7.
• Understand the juice — props and SGPs cost you more than standard −110 markets.
• Respect weather and injuries for totals and player props.
• Use teasers surgically, crossing key numbers.
