March Madness Betting Tips and Strategies
Focus on matchups, tempo, and experience. Mid-major teams with veteran guards often pull off upsets. Unders tend to hit in early rounds when nerves and pressure rise. Look for teams that protect the ball, shoot well from the line, and force turnovers—especially in 5/12, 4/13, or 7/10 matchups.
Live betting is a game-changer during March Madness. Underdogs often jump out early before top seeds adjust. Watch for foul trouble, cold shooting streaks, and coaching momentum swings—then strike mid-game.
Popular March Madness Betting Markets
- Moneyline – Pick the outright game winner
- Point Spread – Back the favorite or underdog with adjusted points
- Over/Under – Total points scored by both teams
- Props – Player points, 3-pointers, rebounds, assists
- Half Betting – 1H/2H totals and spreads
- Live Bets – In-game wagers based on current score
- Futures – Pick national champion, Final Four, or top scorer
