How to use betting bonuses on March Madness
Betting bonuses on college basketball are available at online sports betting sites throughout the NCAA Tournament. Your betting bonuses can help build up that initial bankroll. The strategy applies to the start of the season or during the tournament. It really depends on when you decide to claim a sportsbook’s college basketball betting welcome offer. In most cases, the welcome bonus offer typically applies to your first bet.
Common terms for college basketball betting promos
Every college basketball betting promo has its own terms and services. This is why, before claiming any offer, make sure you understand what’s entailed. It comes down to what type of promo the CBB betting sites are offering. For example, a bet and get requires you to make a minimum deposit and wager (usually in the $5-$10 range) to take advantage of a set bonus amount.
Other sportsbooks offer a first bet bonus in the form of insurance, essentially protecting your initial bet. If your first bet ends up being a losing one, the sportsbook will issue you bonus bets up to a certain amount. If you do receive bonus bets, they come in the form of site credit and are not considered real money. Most of the top March Madness betting sites have a playthrough requirement associated with the bonus before the funds can be withdrawn. Suppose you do win a bonus bet. The sportsbook keeps the bet amount, and you keep the winnings. Always read the full college basketball betting promo terms before taking advantage of a promo.

Types of college basketball betting bonuses for March Madness
Here’s a closer look at some of the most common sportsbook promos you might come across for betting on college basketball and how each one works. These are similar to the familiar NFL betting promos, though you will find some slight differences.
Parlay insurance
Parlay insurance gives you a safety net on multi-leg wagers. With this promo, you’ll first need to place a standard or same-game parlay with typically three or more selections. However, in most cases, if the bet loses by just a single leg, the insurance factor comes into play, as the sportsbook will refund your wager up to the promo limit.
On the other hand, if you get two or more legs incorrect, the bet is considered a loss, and the insurance will not factor into the equation. As an example, let’s say you place a $25 four-leg NCAA Tournament parlay in which Duke, St. John’s, Michigan, and Arizona each must win their first-round game outright. If you qualify for a parlay insurance promo and only three of the four teams go on to victory, you’ll get your $25 stake back.
Bonus bets
Bonus bets are credits that a sportsbook provides either when you sign up or as a special promotional offer. You can use bonus bets to place wagers on the site. Once you use them, the bonus bets are gone, win or lose. If you win, you’ll receive your winnings back, but not the credit amount itself. Remember, site credits are not considered real cash.
For example, say you’ve received a $50 bonus bet after signing up at a sportsbook. You decide to use it on a spread bet for Gonzaga to cover the -14.5 spread in its game against San Francisco at odds of -110, and the Bulldogs win by 17 points. You’ll receive winnings of $45.45 at the listed odds, but not the amount of the bonus bet credit.
Odds boosts
Odds boosts are regularly available at many college basketball betting sites. The sportsbook will boost the odds on various bets, including moneylines, player props, Final Four futures, and same-game parlays. Other operators will offer users tokens that can be applied to the wager of your choice, up to a maximum amount.
By placing a bet with boosted odds, the profit potential for a winning wager increases. For example, let’s say that High Point is a +270 underdog in an upcoming game against Purdue. The sportsbook is offering an odds boost to +350. At odds of +270, a $100 winning wager has a profit potential of $270. A boost to +350 increases the possible profit to $350.
Deposit matches
With a deposit match, the sportsbook provides a bonus that is applied when you add funds to your account. The match typically happens when you first open your account, or as a special promotion for existing users. The amount of the match will vary, such as 20% of your deposit or a straight dollar-for-dollar match up to a certain amount.
The amount of the match may be available right away, or it could be subject to a playthrough requirement. For the latter case, the sportsbook will release the bonus funds in stages, such as $1 for every $25 that you wager at the book. Once the match is available in your account, you can use those funds to place additional March Madness bets.
Bet and gets
For a bet-and-get promo, you’ll be required to wager a minimum amount to receive bonus bets. DraftKings and FanDuel are operators currently offering similar bet-and-get promotions. However, there is a difference in the terms and amounts. At DraftKings, you’ll receive $150 in bonus bets instantly once you have placed the bet.
Meanwhile, FanDuel delivers the $150 in bonus bets only if you win your first wager. Once you receive the credits, you can use them to place additional bets. You don’t have to use them in a single lump sum and can instead spread them out into smaller wagers, but be sure to use them before the expiration date.

College basketball responsible gambling
It’s important to remember that betting on college basketball and any other sport is meant to be a form of entertainment. There are no guarantees that your moneyline, spread, or parlay bet will be a winner. As a result, you should only wager amounts that you are comfortable losing. To ensure it remains a source of enjoyment, always play responsibly and within your limits. If you or someone you know needs assistance, several responsible gambling resources are available via phone and online.
March Madness betting promo FAQ
Yes, for the most part, sportsbook promos are available to use for bets on college sports. However, sportsbooks do have some promos that are only available for NBA or NFL games. It’s a good idea to read the full terms and conditions before using a promo.
When it comes to the NCAA Tournament, there is no such thing as an easy bet to win, as upsets happen regularly. If you’re new to college basketball betting, be aware that every bet carries some level of risk. Consider starting with a simple bet, such as a moneyline (outright winner), and learning all the intricacies before trying a 3+-leg SGP.
The answer to that question really depends on what state you call home. For example, bets placed from New Jersey on Rutgers and Seton Hall are prohibited. Additionally, New Jersey sportsbooks are not allowed to accept bets on any NCAA Tournament games held in New Jersey. Check the terms in your state to make sure you know ahead of time of any March Madness betting restrictions.
