Can 18-year old bettors wager on NCAA Basketball?

18 and over bettors that are located within a state that has enacted regulated sports betting and offers physical sportsbook locations can place a wager in-person, or online if offered, directly with a local sportsbook. The minimum age for in-state regulated sportsbooks is usually 21 years old, leaving 18-year-old bettors only one option; regulated offshore sportsbooks.

US sports betting laws allow for 18+ bettors to use offshore, online sportsbooks to make wagers on athletic contests.

All that is needed is a connection to the internet for 18-year-old bettors to access all the NCAAB betting action available.

Best College Basketball Betting Strategies for 18+ Bettors

First and foremost, 18+ bettors should establish a betting limit for each contest, and it is usually based on a percentage of the gambler’s total bankroll. You can stray from your limits from time to time if the odds seem favorable but developing a limit strategy is key to not going bankrupt prematurely, and to extending the wagering fun.

Another strategy that all 18-year-old bettors should have in their toolbox is the shopping of betting lines. We have several recommended offshore sportsbooks that we suggest using, and they all offer odds that slightly differ from each other.

That said, before you bet on the Kentucky Wildcats favored at 7 points, another sportsbook might be offering a better spread of 6 points, or possibly higher American odds. Shop the odds and play them to your advantage. It’ll earn you the best payout available.

March Madness betting guide for Over 18

March Madness is a nickname for the NCAA Basketball Championship tournament that takes place each March after the college basketball season has concluded. Sixty-eight teams are selected via a variety of means, and they are placed into a tournament bracket where teams can advance if they win but are eliminated if they lose. The team that wins the entire tournament will win the NCAA college basketball national title.

When is March Madness?

  • Selection Sunday: March 16, 2021
  • First Four: March 16-17, 2021
  • NCAA Tournament Round 1: March 18 and 19, 2021
  • NCAA Tournament Round 2: March 20 and 21, 2021

  • Elite 8: March 27 and 28, 2021

Best March Madness Betting Strategy for 18+

If you are betting on a single game in the March Madness tournament, then we recommend setting a betting limit based on a percentage of your bankroll. A popular strategy is to establish a maximum bet of 3% of your bankroll to curb any reckless wagering. It’ll keep you from losing all your money too quickly and will serve to keep the wagering fun going for many more games.

Here are a few recommendations we can offer for filling out an NCAA Championship Tournament bracket.

  • Be realistic about your hometown favorite. It’s a fantastic feeling to have your team involved in March Madness, but unless your favorite team is Duke, then prospective bettors should be realistic about their team’s chances. Look at each game as an individual contest and pick winners using either championship odds or game lines.
  • Home court advantage is essential. Tournament games are hosted in pre-determined locations throughout the country. Sometimes, teams will be assigned to a site that is not too far from their home campus. This is a significant advantage and should be considered when filling out a bracket. If the University of North Carolina is assigned to a Charlotte, NC stadium, then there will be a sea of Carolina blue located in the stands. It matters.
  • Roll with the hot hand. A major factor in how a team plays in the tournament depends on how they have been playing leading up to the tournament. A team may only have a handful of defeats on the season, but if those have all come in February, then that’s a problem. On the other hand, a team may have near double-digit defeats on their record, but they might be on a hot streak as they roll into the tournament.
  • The lowest seed to ever win March Madness was the 8-seeded Villanova Wildcats in 1985. Keep this in mind when predicting winners in the lower half of the seeding.

Who has the best odds to win the NCAAB college basketball championship?

Our top recommended sportsbook, Bovada, has provided odds for which teams are most likely to win the NCAA March Madness college basketball tournament and win the 2021 national title.

These odds will continue to fluctuate as games are won and lost between now and tournament time. The odds will become narrower as the season progresses, and the favorites become more clear-cut, so the best odds will be available early. Be sure to keep up with the latest trends in 18+ sports betting to make an informed wager.
