Conference tournament week is where college basketball starts to feel like full on March Madness. Xavier vs. Marquette in the Big East Tournament first round is a strong example, starting on Wednesday, March 11 at 6:30 p.m. ET on Peacock.
That makes this a smart spot to use the bet365 bonus code TOPACTION, especially because bet365's featured welcome deal is now a brand-new, upgraded value offer: Bet $10, Get $365 in bonus bets win or lose. For new users, this is the best March Madness betting promo that stands out immediately during NCAAB tournament week. It keeps the entry point low, but the return is much larger than a standard low-stakes sign-up deal.
Why the bet365 Bonus Code TOPACTION Stands Out
The main draw of the bet365 bonus code TOPACTION is simple: place a $10 first bet on -500 odds or longer and get $365 in bonus bets win or lose. That structure matters during conference tournaments, where a game can flip in a matter of minutes because of foul trouble, late free throws, or a sudden shooting run. With this offer, your first wager does not need to win for you to unlock the full bonus value.
That is why many users will see this as the best March Madness betting promo currently tied to a low-entry first wager. You can start with one Big East Tournament game, then use the bonus bets on later conference tournament games and the NCAA Tournament schedule that follows.
The Four bet365 TOPACTION Offers Available
The available offers here are:
- Bet $10, Get $365 in bonus bets win or lose
- $1,000 First Bet Safety Net
- Bet $5, Get $150 in Bonus Bets Win or Lose in Illinois
- Bet $10, Get $365 in Bonus Bets + 50 Casino Spins (PA and NJ only)
For most readers, the clear focus is the $365 bet-and-get. It is the simplest offer to activate and the most appealing for a tournament game because it combines a $10 qualifying amount with a large bonus return. The Safety Net may appeal to users who want a larger first-play structure, while Illinois, Pennsylvania, and New Jersey users should pay attention to their state-specific versions.
Why Xavier vs. Marquette is the Right Game to Build Around
Xavier vs. Marquette is not just another midweek game. Xavier enters as the No. 10 seed and Marquette as the No. 7 seed in the Big East bracket, with the winner advancing to face No. 2 seed UConn in Thursday's quarterfinals. That gives the matchup real urgency and a clear tournament angle right away.
Since the game sits in a standalone Peacock window, it also gives readers a clean sign-up timeline. You can register earlier in the day, complete verification, and place your first $10 bet before tipoff instead of trying to do everything at the last minute.
