This offer is especially useful during the NCAA Tournament, where unpredictable results and upset potential all over the bracket create both opportunity and risk. Having a backup plan in the form of this first bet offer allows new players to get in on the tournament action with the opportunity for a second chance if their first bet doesn't go according to plan.
The opening round features several standout matchups that are already drawing attention from college basketball fans. One of the first games on the schedule is the Ohio State vs TCU matchup, with two power-conference teams squaring off for the right to face the Duke Blue Devils in the second round.
Another notable matchup includes High Point vs Wisconsin in a matchup between a 5 and 12 seed that could be a high-scoring game on both sides. While 12 seeds are known for upsets, Wisconsin enters with strong shooting metrics, making this a game where bettors will have to weigh the offensive efficiency of both teams.
Alabama vs Hofstra has also become an interesting game in the first round, though not for the best of reasons. Alabama's second-leading scorer has been arrested in the days leading up to the tournament and is out of action, which could help the Pride keep things more competitive than originally anticipated.
With dozens of games spread across two days, the first round offers unmatched betting volume and variety. From heavy favorites getting the job done to bracket-busting upsets, every matchup has a different angle to consider. By using the BetMGM welcome offer, new bettors can approach the action with added flexibility, giving them a second chance if their initial read on the board does not go as planned.
