Where to Bet on March Madness

Where to bet on March Madness online

Most college basketball bettors cannot make it out to Las Vegas during March Madness to wager on NCAA Tournament games. Fortunately, they still have the opportunity to bet at several trusted online sportsbooks, where they are able to take advantage of numerous different wagering options, receive generous bonuses and participate in March Madness bracket contests.

In fact, some of the most profitable sports bettors have multiple sportsbook accounts so they can shop around for the best possible college basketball lines when March Madness action tips off with the First Four matchups in Dayton and the Round of 64 games at regional sites around the country.

The key to winning big money when betting on college basketball games during March Madness is making sure you get the best numbers and promotions by wagering at top online sportsbooks that give you the most bang for your buck. Some online sportsbooks might even offer a free March Madness bracket contest for their customers as a promo.

What follows is our list of recommended top online sportsbooks for the Big Dance, including Bovada, BetOnline, 5Dimes, MyBookie and GTBets . . .


Bovada is a top online sportsbook for American bettors who value not only having the ability to bet on sports and horses but also like to play poker and casino games, all under one account. It was established in 2011 and bettors who want to open up a Bovada account can also claim up to $250 with a 50 percent first-deposit bonus. Bettors can make deposits and cash out using the popular MasterCard and Visa credit card options.

At BetOnline bettors have many different ways to earn bonuses, both during March Madness and while wagering on other sports at the site. BetOnline offers a 50 percent bonus up to $1,000 for first-time deposits and has some of the earliest posted lines around. This is especially important for college basketball bettors who may want to jump on opening numbers before any major line movement occurs. You can also get $25 in free play to enjoy live betting along with other bonuses for mobile wagering, poker and more.

One of the most popular and oldest sportsbooks online, 5Dimes has been around since 1996 and offers more betting options than just about anywhere else. The top feature for bettors there may very well be the “reduced juice” option for those who play one game at a time rather than more exotic wagering options like parlays and teasers. You can lay less money to win the same amount than traditional bets and also make more with better moneylines, which can be very beneficial in March Madness games as you are wagering on teams to simply beat their opponents rather than covering point spreads.

GT (Game Time) Bets was founded in 2011 and offers bettors a mobile-friendly website and live-betting opportunities, which cover college basketball games throughout the season, including March Madness. Bettors at GTBets can also earn valuable points for every wager through GameTimeRewards, a Vegas-style comp program that pays you back with great prizes such as discounted airline tickets, fine wines and cigars. But maybe more importantly, GTBets has some of the quickest deposit and payout options.
