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, O/U 56.5 points; the teams must score 57 or more 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 champion is 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 before the onset of the regular season.

NFL Playoff Betting

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.

All of the standard bet types are also available during the NFL Playoffs. 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 the traditional type of bets, such as money lines, 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 important 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 number of safe sportsbooks available, players should check as many sites as possible to ensure that the wager they plan to make gives them 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 personal preference, equating to more wins with the right amount of research and experimentation.

Sportsbook Promo Codes

Another huge benefit of the sites we recommend is their 18 and up sportsbook bonuses and promotions. Depending on which sportsbook is chosen, welcome bonuses can be anything from a 50% deposit match to free vouchers or spins in the online casino (if available). Below is a selection of the most popular sportsbook promotions:

• XBet– 100% match on initial deposit, up to $1,000
• BetOnline– 50% welcome bonus, 25% lifetime bonus guarantee.
• Bovada– 50% match on initial deposit, up to $1,000.

18+ Mobile NFL Betting Apps

Almost everyone carries some form of tablet or smartphone around with them at all times. That’s why it’s essential that the sportsbooks we recommend allow for 18+ mobile betting on the go that works well with all current iPhones, iPads, and Android devices. Each of the sportsbooks on this page provides a high-quality NFL sportsbook app.
