Most common sign-up bonuses

The three most common sign-up bonuses in New Jersey range from bonus bets and deposit match bonuses to no deposit bonuses. Each offers unique advantages, and it is important for bettors to understand the subtle nuances to make an informed decision.

Second chance bet

A second chance bet is a wager that will be refunded as site credit or a bonus bet if unsuccessful. Bettors are encouraged to place riskier “longshot” bets than they typically would, with the reassurance of a second chance if they lose. These bets have become a popular choice for New Jersey bettors, offering excellent value for those looking to quickly boost their bankroll. For example, football fans attending a Jets or Giants game in East Rutherford can bet on the underdog with confidence, knowing they’ll get another opportunity to wager regardless of the outcome.

Deposit match

A deposit match is a bonus where the online sportsbook matches a bettor's deposit up to a certain percentage and maximum amount. For example, if you're looking to bet on the New Jersey Devils, the sportsbook may offer a 100% deposit match bonus up to $100. When you deposit $100, the sportsbook will add another $100 to your account, giving you a total of $200 to bet with.

No deposit bonus

A no-deposit bonus is a bonus bet that does not require the customer to deposit any money. They are typically offered during major sporting events like the Super Bowl, World Cup, and March Madness to help increase sign-ups during a time when sports betting interest is at its peak. Some new betting sites also offer no deposit bonuses when launching new sports betting markets.

By lowering the barrier to entry and not requiring a deposit, players are more inclined to sign up and give a great opportunity to interact with the site without losing money. Players can expect a wagering requirement before having the ability to cash out.
