NFL Betting Odds

NFL Bet Types: How To Read Football Betting Lines

• Point Spread – The margin of victory that the favored team must win for the spread bet to win. A team with a spread of -3.5 must win by four or more points to cover.
• Moneyline – Gambling on the winner of the game, regardless of any spreads. To determine favorites and underdogs, odds are given on each team’s likelihood of winning. For example, Baltimore at -250 and Miami at +150 means the Ravens are favored to beat the Dolphins.
• Totals—Also known as the over/under, totals involve wagering on the number of points scored by one or both teams. For example, an over/under (O/U) bet of 56.5 points; the teams must score 57 or more points for the over to win.
• Prop Bets – These are wagers that do not directly affect the game’s outcome and primarily focus on stat totals for players and teams. An example of an NFL prop is “the total number of times Mahomes is sacked.” Super Bowl props for the big game are trendy and will number in the thousands.
• Parlays involve multiple bets combined to secure a greater payout. All wagers must win for the entire parlay to hit.
• Futures – Risking money on futures involves making longer-term predictions, such as placing a wager on the next Super Bowl winner.

NFL Preseason Betting

Gambling before the regular season entails two different categories:

• Preseason NFL Futures: Odds for the winner of each division, conference, and the Super Bowl will be presented as futures and will receive action until the respective champions are determined.
• Preseason NFL Games: Each year, August is filled with preseason football games. Odds on each game are offered up in preseason game betting lines. Still, these can be difficult to wager on due to the unpredictable nature of player rotations leading up to the start of the regular season.

NFL Playoff Betting

All of the standard bet types from the regular season are also available during the NFL Playoffs. The action heats up at 18+ betting sites once the postseason arrives each January.

Fourteen teams will compete for a chance to head to the Super Bowl and win a championship. As more teams are eliminated, fewer games will be played, meaning the last chance for a parlay wager would be during the divisional round.

Super Bowl Betting

Once the playoffs are over, the winners of the AFC and NFC will meet up and decide the winner of that year’s Super Bowl. Betting on future odds for the eventual NFL champion is on the boards all year, but once the matchup is decided, there’ll be game lines and thousands of Super Bowl props across the web.

Because so many viewers tune in to watch the Super Bowl each year, more props and odds are created for it than for any other single event, including the commercials, halftime show, coin toss, National Anthem performance odds, and just about any other occurrence happening during the game.

What Is NFL Live Betting?

NFL live betting (also called in-play) involves placing a wager on a game that has already begun. The odds can change as the game plays on to reflect each team’s performance. Most live betting options still offer traditional types of bets, such as moneylines, spreads, props, and totals.

Game lines can either stay in place and become live after kickoff, or the odds will be transported into a “live” subsection of the sportsbook once the clock starts.

Tips And Tricks For 18-Year-Olds Betting On The NFL

One of the most essential tips for 18-plus gamblers is: “If you are afraid to lose it, you should not risk it.” Bankroll management is one of the most critical parts of gambling for anyone, whether a newbie or a pro.

Another savvy tip is to shop the odds. With the numerous safe sportsbooks available, players should check as many sites as possible to ensure that the wager they plan to make offers the best odds. This trick also works for betting on college football.

Finally, for 18-year-olds, finding a niche can be key. Some players may do their best on spreads, while others play NFL props exclusively for the joy of it. It’s all a matter of personal preference, which can lead to more wins with the right amount of research and experimentation.

Frequently Asked Questions

What are the most common mistakes to avoid when betting on NFL games?

New NFL bettors often make mistakes, such as chasing losses, betting based on emotions, or over-relying on parlays for big payouts. To avoid these issues, stick to a predetermined budget, research team statistics and trends, and focus on single bets, such as spreads or totals, for improved consistency. Always compare odds across sportsbooks to maximize value and avoid betting on every game, as selectivity is key.

How do I interpret NFL betting trends to make smarter wagers?

NFL betting trends, like a team’s performance against the spread (ATS) or over/under results, can guide your bets. For example, if a team consistently covers the spread as an underdog, they might be a good pick in similar scenarios. Check statistics such as home/away performance, recent form, and head-to-head records. Combine trends with current factors, such as injuries or weather, to make better decisions.

How can I manage my bankroll effectively for NFL betting?

Set a fixed budget for betting and never wager more than you can afford to lose. A common strategy is to bet 1-2% of your bankroll per wager to minimize risk. Avoid chasing losses with larger bets and spread your wagers across multiple games or bet types to diversify your risk. Track your NFL bets to identify what works and adjust accordingly.

What role does home-field advantage play in NFL betting?

Homefield advantage typically gives NFL teams a slight edge, often reflected as a 2-3 point boost in the point spread. Home teams benefit from crowd support, familiarity with the stadium, and less travel fatigue. However, its impact varies. Check team-specific home/away ATS records and consider factors like cross-country travel or neutral-site games before betting.

How do weather conditions affect NFL betting?

The weather can significantly impact NFL games, especially for outdoor stadiums. Heavy rain, snow, or wind often leads to lower-scoring games, making the under a safer bet for totals. For example, strong winds can hinder passing games, affecting teams reliant on quarterbacks. Check weather forecasts for game day and focus on teams with strong running games in adverse conditions.

How can I bet on NFL Holiday Games?

18 and up bettors can wager on NFL  Christmas games and Thanksgiving games, with both domestic and online sportsbooks. However, given the holiday season, some domestic sportsbooks will likely be closed during the holidays. Contrarily, online sports betting sites operate 365 days a year and can be accessed online, providing both convenience and accessibility.
