How to Bet on March Madness
March Madness Bet Types
Legal March Madness betting draws over $3 billion in wagers annually, making it one of the world's biggest sporting events. Betting on March Madness on betting sites and retail sportsbooks will only get bigger.
You'll have many March Madness betting options to choose from once the Division I Basketball Tournament tips off. The best March Madness sportsbooks update odds as the tourney rolls on.
Some states and respective March Madness betting sites also allow individual player props, such as over/unders on players' points or rebounds. Remember that some states do not allow betting on in-state college teams.
- Moneyline: Moneyline betting is the simplest basketball wager because it only requires picking the winning team. However, the odds will be different for the favorite and underdog.
- Futures: Futures betting revolves around a distant outcome that could be weeks or months away. For instance, an October preseason bet on March Madness would qualify as a wager. However, you'll still see plenty of futures available on March Madness betting sites after the event begins and progresses through the rounds.
- Point Spread: Spread betting, point spreads, or simply "spreads," assign a handicap to each side. The favorite will start with a point deficit (-6.5), while the underdog begins with a point surplus (+6.5). In this example, the favorite would need to win by seven points or more. Meanwhile, the underdog would have to lose by six points or less.
- Totals: Betting on the over/under is one of the most popular betting types. An online sportsbook sets a total line, and you bet over or under that mark. If you take the over on a 140.5 line, you'd need two teams to combine for 141 points or more.
- Props: Prop bets offer the chance to wager on outcomes besides final scores and winners. Examples of props include leading scorers, leading rebounders, and the John Wooden Award winner.
Prop Betting Restrictions for March Madness
In many legal sports betting states, U.S. sports bettors to place single wagers on college basketball teams.
But recently, there has been a nationwide push to restrict some types of bets on college basketball. Some states let you bet on every outcome, including prop bets. Other states, meanwhile, have implemented restrictions on prop bets in an effort to protect college players.
Props are markets on specific outcomes during a game. Often, prop bets have little bearing on the game's result.
Team prop bets are wagers on specific team totals. Props can include wagers on points for specific quarters or halves.
Individual player props are typically Over/Under bets on markets such as Total Points and Total Rebounds.
It’s important you know the rules in your state before placing any bets, and you should always check the individual NCAAB betting site to see what types of bets are offered.

Essential March Madness Betting Tips
One of the most fun things for any college basketball fan to do during March and April is selecting their brackets for The Big Dance. The betting favorites could determine the team with the best chance to win the March Madness tournament.
Testing your college basketball game expertise and using your betting knowledge is the key to your success in March Madness bracket betting.
Compare Odds
Some apps have very different tourney odds from each other, especially in the early going. You always want to find the best prices for betting on a college basketball game. You'll find the greatest discrepancies in the first round when matchups are more uneven.
Track Underdogs in Smaller Conferences
Some conferences don't get much publicity nationwide but still produce good teams. For example, the Horizon League (e.g., Milwaukee, Cleveland St., Oakland) doesn't receive much press. But did you know it has a 19-19 March Madness record since 1985, despite normally facing giants? Schools from under-the-radar conferences typically offer more value on March Madness online betting lines.
Watch for Reverse Line Moves
A reverse line move is when sportsbooks shift odds in an unexpected direction. For example, let's say that Virginia (-8.5) has 80% of the public betting action. Nevertheless, most gambling sites downgrade Virginia's spread advantage to -7. This move indicates that smart money is on the underdog, and you might want to consider joining the sharps.
Responsible Gambling on March Madness
March Madness is one of the most thrilling events in sports and can be enjoyed further with responsible gaming.
Remember: the NCAA tournament spans nearly a month. There will be emotional highs and lows, and it’s important to remain level-headed and responsible with your bankroll.
We suggest not wagering more than 1% to 3% of your bankroll on a single game. Assuming you only have $200 or so, then at least avoid betting more than 5% to 10% on one game.
Never chase your losses. Games begin early in the afternoon and can go well past midnight. If you have a rough day, don’t unload your entire bankroll, hoping to make all your money back. This is not responsible bankroll management; the last thing you want is to blow all your money on the first day of the tournament.
Remember that betting on in-state college teams is not allowed in some states.
Betting responsibly is key to enjoying March Madness.
