Types of March Madness Bets You Can Make
Whether you’re betting casually or grinding for profit, March Madness offers something for every type of bettor:
- Moneyline Bets: Bet on which team will win, regardless of the spread.
- Point Spreads: Bet on a team to win or lose by a certain number of points.
- Over/Under (Totals): Bet on the total number of points scored by both teams.
- Futures: Bet on a team to win the championship, make the Final Four, or win a region.

March Madness Betting Tips for 2025
1. Don’t Chase Favorites – Upsets happen. That’s the madness. Betting blindly on 1 and 2 seeds won’t always work.
2. Watch for Value in Totals – College basketball totals can be volatile. A sharp edge often exists in O/U bets.
3. Line Shop – Use multiple betting sites to find the best odds on your picks. A half-point can swing your profit.
4. Beware the Hype – Public money floods the market in March. That can skew lines in favor of underdogs.
5. Pace of Play Matters – Teams with slow tempos often play lower-scoring games. Adjust your totals bets accordingly.
Are March Madness Betting Sites Legal?
Yes — in many U.S. states. But it depends on where you live. As of 2025, over 30 states have legalized online sports betting. Top sportsbooks like DraftKings, FanDuel, and Caesars are fully licensed and regulated, meaning your money and personal data are protected.
Always make sure you’re using a legal site based in your state. Avoid offshore sportsbooks that lack transparency or accountability.
Final Word: Pick the Right Platform for Your Madness
March Madness isn’t just a betting opportunity — it’s an experience. The highs, the heartbreaks, the last-second threes… and if you’re wagering smart, the payouts.
Whether you’re filling out 10 brackets, betting live spreads, or hunting underdog futures, having the right sportsbook makes all the difference.
So pick your team. Find your site. And let the madness begin.
