All of our sportsbooks undergo the same rigorous ranking process, but March Madness betting requires some specialized criteria that goes beyond standard sports betting evaluation.
We examine how competitive each site’s lines are across both tournaments, paying special attention to futures markets and whether they offer early championship odds that provide real value before the brackets are announced.
The best March Madness sites go beyond basic betting by hosting bracket challenges, survivor pools, and unique tournament-specific contests that add extra layers of excitement to the three-week event.
Tournament season creates a surge in winning tickets, so we prioritize sites that maintain their usual withdrawal speeds even during the busiest betting periods of the year.
March Madness can be chaotic, and bettors need quick resolution when issues arise during crucial betting windows; we test response times and knowledge levels specifically during peak tournament activity.
Tournament betting requires a different approach than regular season wagering. Here are the insider strategies our experts use to gain on edge during the three weeks of madness:
Everyone bets on schools like Duke and North Carolina, but the real value often comes from smaller conference champions. These teams might not have faced tough competition all season, but they’re coming off winning their conference tournament and playing with serious confidence.
Tournament basketball is different from regular season play, and coaches who’ve been to multiple Final Fours know how to manage the unique pressures and make the right adjustments when games get tight in the final minutes.
Casual bettors love backing teams that looked amazing in their last few games or betting against teams that struggled recently. This creates line movement that sharp bettors can capitalize on, especially in the first weekend when public money heavily influences spreads.
Teams that earned high seeds and conference tournament byes often have a significant rest advantage over squads that had to grind through multiple games. In the first round especially, that extra rest can be the difference when teams get tired, especially in the last few minutes.
While high-scoring teams get the attention, tournament success historically favors teams that can get stops when they need them. Defensive efficiency metrics often predict March performance better than offensive statistics, especially when games slow down in pressure situations.
You can bet on March Madness in two different ways: game-by-game bets or bracket contests. Each approach has its own advantages and risks, so understanding both helps you choose what works best for your budget.
Traditional betting lets you focus on individual games with standard point spreads, totals, and moneylines, similar to how you might approach NBA betting but with the added suspense of single-elimination tournament play. You can pick and choose your spots based on matchup analysis and situational factors. Each bet is independent, meaning one bad result doesn’t doom your entire tournament strategy.
Bracket betting, on the other hand, is essentially a tournament-long lottery ticket with astronomical odds but potentially life-changing payouts. BetNow leads this space with their massive million-dollar bracket challenges, though most bracket contests require you to predict all 63 games correctly, a hard feat to accomplish! Even getting close to perfection can net significant prizes in large-pool contests.
The middle ground might be the most practical approach for many bettors. Some sites both offer bracket contests where you only need to predict certain rounds correctly, or survivor-style pools where you pick one team each round to advance. These formats offer better odds than full bracket prediction while maintaining that full tournament excitement that makes March Madness special.
