Author: Devin Erickson-Sheehy | Last Updated: August 9, 2023 | Fact Checked By: Josh Collacchi

Just like any industry, the world of online gambling is competitive. There are a wide variety of features and capabilities that differentiate one site from the next. But online gambling bonuses might be the biggest draw.

Whether it’s a sportsbook, online casino, poker site, horse racing platform, or fantasy sports site, customers look for the best value. It starts with sign up bonuses, which customers get as soon as they register for an account.

After that, online gambling sites have to give customers a reason to stick around. That’s where ongoing bonuses and loyalty programs come in.

At American Gambler, we have gathered all of the top sign up bonuses, so you can see what all of the best betting sites have to offer. Now, we will go over all of the different kinds of online gambling bonuses you will find and what they mean, giving you a better idea of how to use them.

Types of Sign Up Bonuses

First thing is first, and that is claiming a sign up bonus. On our site, you can look to see what your state offers. All of the gambling apps we have are completely legal to use.

In our gambling site reviews, we go over how you can secure the welcome offer. Some require promo codes, while others just have specific terms and conditions you need to follow.

As the industry develops, gambling sign up bonuses are becoming more creative. But, there are a few types of online gambling bonuses that you will see used most often.

Deposit Match

A deposit match sign up bonus will depend on your deposit. This bonus can be 100% of your deposit, or just 20%. But the main value lies in the playthrough requirements.

For example, let’s say there is a 100% deposit match and you deposit $100. The gambling site would give you an additional $100 in bonus money.

That bonus has to meet the wagering requirements before you can withdraw. This is where it can be very different for a sportsbook versus an online casino. A sportsbook will often have just 1X playthrough requirements, but online casinos can have up to 20X playthrough requirements.

If an online casino has 20X playthrough requirements, you have to wager 20X your bonus in order to withdraw any winnings. The lower the wagering requirements – the better!

Bonus Bet

A bonus bet is usually associated with sportsbooks, but it can be offered for casinos too.

For a sportsbook, you get your first bet back in bet credit if your don't win. If it loses, you get a bonus of the same amount. This bonus has to be wagered, but any winnings are cash.

Online casinos sometimes offer bonus play for a certain amount of time, such as 24 hours after signing up. Your losses are recouped, but that bonus money has to meet the playthrough requirements.

No Deposit Bonus

A no deposit bonus is just how it sounds. Online gambling platforms want to show off features, and some are willing to give you bonus money to try it out.

Since no deposit is required, these online gambling bonuses aren’t that high in value. Oftentimes, they are around $20 in value, but it gets you betting or playing casino games without risking a cent of your own money.

It's most common to see these during the launch of a new state. For instance, in 2023, Kentucky sports betting promos might feature them.

Free Spins

Free spins are only offered for online casinos and are often paired with a deposit match.

Usually, an online casino will provide free spins for a particular slot. It can be the most popular, or a new slot that the casino wants to promote.

Ongoing Bonuses & Betting Promotions

The best gambling sites will still provide a range of promotions to use after you have used the sign up offer. Go to the promotions page of the site or app to see what bonuses are active.

Here are some of the most common online gambling bonuses that are offered to current customers.

Reload Bonus

Reload bonuses are a lot like deposit matches but are offered for current customers. Instead of being 100% matches, they are usually a little less.

Some gambling sites have reload bonuses every week on a certain day, such as Fridays. It’s the key time to fund your account.

Refer-a-Friend

Here is an easy way to get bonus money. Have a friend who has yet to sign up for the gambling site you use? It probably has a referral bonus you can use.

Unibet referral bonus

Simply send a link to your friend to sign up. As soon as they deposit, you will get a bonus.

Boosted Odds

The best sportsbooks will have plenty of boosted odds, especially for local teams.

Let’s say the Yankees have -110 odds of winning. A sportsbook could add a boost and make the odds +100, which will increase your winnings if the bet hits. Boosted odds will be on the main page of the betting site.

Insurance/Cash Back

We talked about bet credits, and insurance bonuses are a lot similar. The most common insurance promos are for parlays.

A parlay insurance bonus will give you a refund if you hit every leg except for one, which is always the worst part of losing parlay.

A casino can offer cash back or insurance for a game, such as Blackjack. The amount you lose over a period of time will be given back in bonus money.

Prize Giveaways

Gambling sites will offer prize giveaways, ranging from hotel stays to tickets to big games.

Sportsbooks will often have prize giveaways that have to do with local sports teams. You can win season tickets to your favorite NFL team or even jerseys.
