Introduction

The NFL continues to dominate U.S. sports betting, with legal online platforms now active in 38 states. Whether you're placing your first bet or refining your strategy, this guide cuts through the jargon to explain core concepts for the 2025 Season.

Top NFL Bet Types

Point Spreads

Teams are handicapped with a +/- margin. Example: If Buffalo Bills are -2.5 vs LA Rams, they must win by 3+ points. Standard odds: -110 (bet $110 to win $100).

Moneyline Bets

Straight-up winner wagers. Favorites show negative odds (-200 = bet $200 to win $100), underdogs positive (+180 = $100 bet wins $180).

Over/Under Totals

Predict combined team scores. A 45.5 line means bet "over" if you think both teams score 46+ points total.

2025 Odds Breakdown

Three formats dominate:

American Odds

+300 = $100 wins $300
-200 = Need $200 to win $100

Decimal Odds

3.00 odds = $100 bet returns $300 total

Fractional Odds

3/1 = $100 stake yields $300 profit
