Four teams are eliminated in the First Round (known as the First Four), leaving 64 teams then split into four regions of 16 teams each. Each team is then seeded 1 through 16 in their regional bracket.

Based on regular season results, the strongest teams rank #1 in their regional bracket and so on. Losers are then knocked out in progressive rounds leaving a Round of 32, the Sweet 16, the Elite 8, the Final Four and then, the final to decide the NCAA National College Basketball champion.

Popular Types of March Madness Bets

Sports betting beginners and even more experienced bettors can easily become confused by the seemingly endless choice of bet types offered by NCAA March Madness sites.

Let’s break it down; popular bet types and what to avoid as a beginner;

  • Money line – A simple win bet on any single March Madness game at set odds on your chosen winning team.
  • Points Spread – Fans love March Madness Points Spread betting because they create interest on both sides. For example, if you are betting on Gonzaga vs Baylor this may involve giving the ‘Zags a head start (+4.5) or handicapping the Baylor Bears (-4.5). Your team may lose the game, but if they finish inside the spread, you still win your bet!
  • Total points (Over/Under) – Place your bets on the combined point totals of the March Madness teams competing in a single game to be ‘under or over’ the points total offered by the sportsbook. For example, betting on Villanova combining with Illinois to score over or under a collective 141 points.
  • Prop Bets – The number of possible March Madness prop bets are too numerous to mention. They can vary from the number of points, assists or rebounds for a specific player, the first points scored by any player or team in a match, through to even obscure wagers on half-time/full-time scores.
  • Futures Betting – This is a very popular bet type on the overall National Championship Winner, which teams make it through to the Final Four or even winners of the NCAAB Freshman of the Year or John R. Wooden Award for outstanding NCAAB player of the year.
  • In-play Live Betting – Place live wagers on March Madness games at changing betting lines/odds in real time. Odds are almost always reset at halftime in March Madness matches.

Betting options beginners should avoid (or check for special promotions only)

Parlay Wagers – Parlay Bets are usually best avoided by rookie bettors, however, there is good news that many March Madness betting sites are beginning to offer promotions to lessen the risk for beginners to try parlays to educate and gain further experience.

Parlay wagers are an accumulated number of wagers (each bet is referred to as a ‘leg’) taken over a selection of March Madness matches. With each win in the parlay bet, the odds accumulate with each successful winning leg. However, if only one leg of your parlay wager loses, your entire parlay bet stake is usually lost.

Lessen your Parlay Betting Risk – If you are a beginner and you would like to give parlay betting a shot, many of the best and recommended online sportsbooks now offer permanent ‘win your Parlay wager, if you lose only 1 leg’ or ‘Parlay Insurance’ promotions, which cuts your risk and helps you gain invaluable experience while giving you more winning opportunities to boot.

Live Betting

If you are a fan of NCAA Basketball and in-play live betting, there is no better time of the year for you than March Madness!

March Madness live betting allows you to place your wager as the action plays out on the court, with online sportsbook odds updating on-the-fly in real time as the game unravels.

Done right, live betting is more exciting than pre-game betting, and most, if not all the same markets are available. What’s more, many sportsbooks combine a ‘cash out’ option when live betting to opt out of your wager if it looks like losing at any point of the match.

Using in-play live betting and cash-out together can help maximize your wins and minimize your losses, and of course to keep in touch with the betting action anytime-anywhere, mobile live betting is featured by most of the quality March Madness betting sites in New Jersey.

Kentucky hasn’t been to the Final Four since 2015, and that’s a long time in the Bluegrass state. The Wildcats are led by senior forward Oscar Tshiebwe who was the 2022 National Player of the Year and led the nation in rebounding. As always, the Wildcats brought in a super freshman class, led by guard Cason Wallace.

The Cougars have become big-time contenders nationally, reaching the Final Four in 2021 and the Elite Eight in 2022. This year they welcome back starters Marcus Sasser and Tramon Mark who missed most of 2022 with injuries, and hey, March Madness ends just a few miles away from Houston’s campus. If they can get there, it will be a heck of a homecourt advantage.

It’s Drew Timme time out on the West Coast for the Zags. After a shocking loss in the Sweet 16 last year, Gonzaga brings back multiple starters seeking the school’s first March Madness title. Timme is a 6-foot-10 forward with a soft touch around the basket. He averaged 18.4 points last year and should be the focal point of the Zags offense.

The Bears still have a few pieces from their 2021 title-winning team, including senior guard Adam Flagler, who led Baylor in scoring last year with 13.8 points a game. The Bears play fantastic defense and should get a boost from incoming freshman guard Keyonte George.

The defending champs finished last season 34-6 but lost a lot of production to graduation and the NBA Draft. So, who takes over for the Jayhawks? Look for Coach Bill Self to rely on junior Jalen Wilson down low and point guard Dajuan Harris Jr. to run the offense.

Tips and strategist for March Madness betting 

Think about whether you want to play it game-by-game, round-by-round or pick a few teams to ride all the way to the Final Four. March Madness provides lots of options for bettors.

  • Sometimes the best way to earn a win is to bet on an underdog team to get through to a round they are not expected to, such as Oklahoma State to make it to the Final Four for example.
  • March Madness always includes at least one Cinderella team, so keep your eyes open for a team from a small conference that has big players and a big heart.
  • Whatever you do, keep your personal bias out of your March Madness betting decisions. That is the sure-fire way to throw your money away.
  • If you are taking out a Futures Wager on who will win March Madness, the sooner you bet before the tournament begins or runs too deep will ensure you receive the best odds possible.
  • When betting over/under or totals betting pay attention to teams with incredible defenses or offenses. For example, betting the over on the #1 offensive team in country is a very sound wager.
