If you want to make the most of your First Four bets, online sportsbooks offer some of their biggest promotions of the year for the NCAA Tournament. Below, we break down the top First Four promos for March Madness available right now, allowing you to maximize your wagers and boost your bankroll.

First Four best bet 16 St. Francis (PA) vs. 16 Alabama State: Alabama State -3.5 (-110)
Alabama State fought into the NCAA Tournament by winning the Southwestern Athletic Conference as the fourth seed. The team has been playing well to end the season, winning 10 of its last 11. CJ Hines has been hard to stop, scoring 20, 15, and 15 points in the three games to lead the Hornets to the NCAA Tournament. When the game is close, Hines will make the big shots to put the game away, and St. Francis appears less likely to have a player who can match that.

First Four best bet 11 North Carolina vs. 11 San Diego State: North Carolina -3.5 (-110)
There has been a lot of talk about North Carolina not deserving its spot in the NCAA Tournament, and the committee shared that it was the last team to receive an at-large bid. Watch the Tar Heels put an end to those comments quickly by showing they belong against San Diego State. The Tar Heels were way outside the bubble in early February, but over the last month, they have won eight of 10 to make it in.
A big reason they have made it in and could have a chance to go on a run is the play of freshman guards Drake Powell and Ian Jackson. As they have gotten more minutes, they have had some big games, and the elevated guard play is why Carolina beat San Diego State and potentially could go on a run in the NCAA Tournament.

BetMGM is offering a first-bet offer up to $1,500, giving new users a safety net for their first wager when they sign up using the code THELINES. Place your first bet after signing up and depositing at least $10, and BetMGM will provide a refund of up to $1,500 in bonus bets if it loses.

First Four best bet 16 Mount St. Mary’s vs. 16 American: American -1.5 (-110)
American has finished the season strong, winning the Patriot League regular-season championship and the conference tournament. Mount St. Mary’s will have its hands full trying to stop Matt Rogers, American University’s top scorer at 17 PPG. He dropped 25 in the Patriot Tournament final to lead the Eagles to the NCAA Tournament.
Bet365 First Four March Madness betting bonus code: $150 in bonus bets or safety net up to $1,000
Bet365 Sportsbook is giving new users a choice between two welcome promos with the bonus code THELINES:

First Four best bet 11 Xavier vs. 11 Texas: Texas +130
At the start of the season, most had higher hopes for Texas than barely making the NCAA Tournament and having to play in the First Four. It doesn’t matter now, though, and the Longhorns are still loaded with talent. Tre Johnson is one of the best freshmen in the country.

First Four teams NCAA Tournament history
Teams in the First Four are often overlooked, as they are either 16 seeds or four of the last at-large bids to get into the NCAA Tournament. Since 2011, at least one First Four team has won a first-round game in every season but one (2019). In 2011, VCU started as an 11 seed in the first four and beat USC en route to another four wins, making it to the Final Four. UCLA did the same thing, winning its First Four matchup before going to the Final Four.
Don’t forget that 16-seed Fairleigh Dickinson won its First Four game before going on to beat 1-seed Purdue in 2023. Last season, 10-seed Colorado won its First Four game and then went on to beat 7-seed Florida in a 102-100 barn burner. What we’re getting at is don’t overlook the First Four teams; history tells us at least one of them is likely to win a first-round game.
