Best New Jersey Online Sportsbook Bonuses, Promo Codes, & Bonus Bets

Since sports betting was legalized after the overturning of PAPSA, an out-of-date law that effectively banned sports betting in all but four states, New Jersey has become a mecca for online sports betting. With several online sportsbooks live in the state, the competition is fierce, and each sportsbook offers various bonuses, promo codes, and other exciting promotions in exchange for giving their software a try. These include some of the best NJ sportsbook promos, which provide attractive sign-up offers and a variety of options for sports bettors.

New Jersey online sportsbooks are known for their competitive promotional offers, including lucrative welcome promotions and live betting experiences.

Top NJ Online Sportsbook Bonus Offers & Promo Codes

With all the options being offered, it can get overwhelming. No promotions are created equal and each comes with its own terms and conditions.

It is very important to understand the different types of bonuses, whether you need a promo code, what strings are attached and how to take full advantage of each offer. Most are a one-time deal, so be sure to take a look at our extensive guide to the best NJ online sportsbook bonuses, and promo codes to optimize your bankroll. Bonus bets expire, so always check the expiration period and any rollover requirements before using them for wagering.

What Is a Promo Code? And Why Use One?

When claiming a bonus offer or welcome package from a New Jersey online sportsbook, a promo code may or may not be necessary. When a promo code is needed, it acts like an online coupon.

A promo code is entered either during registration or during the deposit process. Here at RotoGrinders, we have walked you through the process for each site to help you get the maximum value out of each welcome package to help turn the odds in your favor.

Eligible bettors can also enjoy a wide variety of sports betting markets, including options like darts, lacrosse, volleyball, same-game parlays, and live betting.

Why Do Online Sportsbooks Offer Welcome Packages?

Online sportsbooks, like any business, are here to make money. So, you may wonder why they are seemingly just giving money away?

Competition in a very crowded online sportsbook market is fierce. Online sportsbooks offer these welcome packages in order to get you to check them out, in the same fashion as a car dealer may offer three oil changes with the purchase of a new car. The dealer is going to eat the costs of the maintenance in hopes that you will like the service you receive and return for future vehicle services.

These welcome packages are specifically designed to attract sports bettors by offering various incentives such as first bet insurance, deposit matches, bonus bets, and ongoing promotions tailored to their needs.

These welcome packages also come with terms and conditions. These are designed for you to play a bit on their site and get acquainted with its offerings in hopes that you will become a repeat customer. Some sites require a bet to be placed while others require you to play through the bonus money before withdrawing your money.

Sportsbook Bonus Jargon

Before you sign up for a sportsbook bonus in NJ, familiarize yourself with the jargon below so you know what you’re getting yourself into. NJ sports betting promos come in various forms, such as first bet insurance, bonus bets, and deposit matches. Understanding these promos and their terms and conditions is crucial for making the most of the offers available in the New Jersey sports betting market.

No Deposit Bonus

For those of you that are curious about sports betting, but are not quite ready to pull out your credit card, a no deposit bonus is a dream come true. Simply register for a new sportsbook account and enter a promo code (if necessary) and the bonus amount will be added to your account.

Since nothing is truly without cost, a no deposit bonus will often come with a wagering requirement. A wagering requirement is how much you need to wager before money can be withdrawn, and is usually 1x, 5x, or even 25x the bonus amount. Some no deposit bonuses allow you to only keep winnings and others will allow you to keep the bonus and your winnings. Bets can be made all in one shot, or can be made in several smaller bets as long as they add up to the wagering requirements.

No deposit bonuses will often be the smallest dollar amount of all the bonuses but are still an exciting and easy method to test the waters and find the right sportsbook for you.

Additionally, there are various NJ sportsbook promos available, including first bet insurance, deposit bonuses, bet credit refunds, and bonus bets.

Bonus Bets

Another popular promotion that online sportsbooks are offering is a bonus bet. Bonus bets come in many forms so be sure to check which bonus bet is being offered before placing your first wager. Remember, bonus bets expire, so it’s important to check the expiration period and any rollover requirements before using them for wagering.

Deposit Bonuses

The most popular of all the bonuses, the deposit match bonus is pretty straight forward. When you make a deposit, the sportsbook will match the amount of your deposit up to a certain percentage. Most sportsbooks will match 100% of your first deposit up to a certain amount, though it’s not unheard to see both lower and higher percentages.

In addition to deposit bonuses, there are a variety of New Jersey sports betting promos available, including deposit bonuses, free bets, and risk-free bets. These deposit bonuses can be placed in one big bet or broken up into smaller bets. In order to make these bonuses available for withdrawal, there are a few strings attached. They all come with wagering requirements and a time limit to in which to clear the bonus. If the wagering requirement or time limit isn’t met, the bonus will expire and be removed from your account.

Odds Boost

Online sportsbooks will routinely offer “boosted odds” on select games. Often only announced a few hours before the game starts, specific bets will have better odds listed. For example, if the Sixers are listed at +150 against the Celtics, BetMGM may send out an email promoting an “odds boost” and bring the line to +220. This is a popular promotion by several books on certain prop bets like the first player to score a goal or if Joel Embiid will have a triple-double.

Be sure to check that the odds are actually boosted. Odds change often as different factors may change before a game starts. We have found that some parlays actually pay out better if you simply build them yourself.

For example, an odds boost may be offered the day before the games start for the Sixers, Clippers and Lakers all to win at +225. That day it is announced that Kawhi Leonard is taking an “load management” day off dropping the odds on the Clippers winning from -200 to +100. This may change the odds of the parlay to +250 if you build it yourself.

Refunds/Bonus Back

Bettors can bet more confidently knowing that a percentage of their wager will be returned if the game ends up not going their way. Some sportsbooks will offer a percent back ranging from 25% up to 100% on certain bets, meaning if you wager $100 on a 50% refund promo and it doesn’t pan out, you would get $50 put back in your account.

Be sure to check how the refund will be awarded to your account. If it is refunded as cash, your money will be immediately available for withdrawal. If you receive the refund in a one-time bonusbet, be aware that most sites will only pay out profits from a bonus bet and not the bet amount.

When the refund is given back as site credit, you will usually get the bet amount plus profit on winning bets, but you will be required to bet all the site credit before the money is available to withdraw.

VIP/ Loyalty Programs

Long after you have used the welcome package offerings, many online sportsbook provide VIP or loyalty programs that will convert every dollar wagered to points or tiers which can later be redeemed for cash, comped rooms at their land based hotels, prizes and more. Since most online sportsbooks are also affiliated with online casinos and online poker rooms, often these tiers or rewards points can be combined with existing accounts.
