Are Casino Bonuses Worth it?

The short answer is yes.

1. Online casinos give you bonuses in exchange for completing tasks, such as making deposits and bets.
2. These bonuses give you free spins or betting credits you can use in place of your own money.
3. Anything you win by using bonus spins/cash is credited to your account and withdrawable (i.e. turned into real money) when you complete the wagering requirements.

One final thing to note about online casino bonus offers & promotions is that they need to be fair. That’s why you should only use licensed online casinos recommended by us. Our top online casinos not only offer generous bonuses, they do so in a fair and lawful way at Top Online Casino Bonuses September 2024.

Top 10 Online Casino Bonus Types

Bonuses and promotions are the finest ways to take advantage of everything that the top online casinos have to offer. Indeed, games are what all online casinos primarily provide. But bonus money is necessary if you want to get the most out of every game.

What is bonus money? It’s site credit that allows you to play online casino games without spending your own money. For example, if you used one of our exclusive deposit bonus codes to create a new casino account and claim $100, that money can be used to play real-money games. Anything you win is yours to keep once you complete the wagering requirements at Top Online Casino Bonuses September 2024.

Essentially, you’re able to turn nothing into something with casino bonuses. That’s why they’re an integral part of the gambling sites and, in turn, why they give you maximum value from your time online.

1. Online Casino Signup Bonus

Every online casino welcomes new players with a bonus. In actuality, a lot of online casinos offer a comprehensive welcome package. Why do both new and well-known online casinos give new players anything extra?

Because the online gambling industry is competitive. Customers like you have dozens, if not hundreds, of options. Therefore, a gambling site needs to stand out from the crowd. A good way to get people’s attention is an eye-catching welcome bonus at Top Online Casino Bonuses September 2024.

2. No Deposit Casino Bonuses USA 

No deposit bonuses are fairly self-explanatory i.e. you get free spins, bonus credits, or some other reward without making a deposit. The best no deposit casino bonuses are typically reserved for new customers.

For example, if you want no deposit offers now, you can create an account with BetMGM. As long as you’re a new customer, you’ll get $25 when you join. All no deposit USA casino bonuses have wagering requirements. Therefore, you will need to make a deposit at some point so you can wager your own money at Top Online Casino Bonuses September 2024.

However, when you claim the best no deposit bonuses for new customers, you’ll also get something extra when you add funds to your account. This means you’ve got two reasons to make an initial deposit i.e. so you’ve got cash in your account to clear your sign-up bonus and so you can get the first deposit welcome bonus.

3. Recurring Casino Bonuses for Existing Players

Deposit bonus codes and promotions aren’t just for new customers. Even though you typically get the biggest online casino bonuses as a newbie, there’s plenty of ongoing value if you’re a real-money customer at Top Online Casino Bonuses September 2024.

Therefore, in addition to new customer casino offers, you can get your hands on reload bonuses, loyalty rewards, and more. You can scroll through the list below to learn more about the most popular online casino offers for existing customers.

4. High Roller Casino Bonuses

We often direct newbies and recreational players to the best deposit bonus sites. We do this because they have large deposit multipliers. This means you get a decent amount of bonus cash by making a relatively small deposit at Top Online Casino Bonuses September 2024.

These top-rated deposit bonus casinos are also great for high rollers. However, the multipliers aren’t as meaningful. Because of this, it’s worth looking for high roller top gambling offers. These deals unlock exclusive online casino bonus offers when you deposit/stake more than the average consumer.

5. Free Spins Casino Bonuses

You don’t always get betting credit when you claim online casino bonus offers. Some deals give you free spins i.e. bets you can use to play online slots. Bonus spins have wagering requirements like all online casino promotions.

The wagering requirements you need to consider when you’re playing for free spin bonuses are:

• Do you need to make a minimum deposit/minimum bet?
• Do you need to use a bonus code?
• Can you use your free spins on all online slot machines or are they restricted to certain games?
• Are free spins winnings paid out in real money or bonus cash that can only be withdrawn once you hit a playthrough target?

The best free spins casinos have lenient wagering requirements Therefore, if you’re aiming for free spins offers, make sure you get the most value and least restrictions at Top Online Casino Bonuses September 2024.

6. Mobile Casino Bonuses

The best casino apps are great for gaming on the go, but they can also be the source of special bonus code offers. It’s worth noting that almost all casino bonuses you can claim via a mobile app will also be available on the operator’s desktop site. However, in some cases, you’ll be able to get exclusive promotions that are only unlocked when you play mobile casino games.

7. Game-Specific Bonuses

In the same way free spins are reserved for online slots, there are certain offers designed for specific games. A great example of game-specific promotions are cashback bonuses. We’ve described these promos in more detail below. However, if you have a cashback bonus for blackjack, it means you get a refund on losses when you play this game at Top Online Casino Bonuses September 2024.

8. Reload Bonuses

Reload bonuses are deposit bonuses for existing customers. Newbies get big casino bonuses when they make an initial deposit. Once you’ve gone through this process, you’ll have opportunities to get something extra when you add additional funds to your account. Some of these promotions require deposit bonus codes, some don’t.

What’s always the case, however, is that you need to make a qualifying deposit to get your reward. In general, reload offers aren’t as lucrative as first deposit bonuses. However, the best online casino bonuses for US players have deposit multipliers topping 50%.

9. Cashback Bonuses

Cashback bonuses give you a percentage of your losses back when you play certain games. There will be a max cash amount, so you don’t get a full refund. Additionally, the rebates are based on your net loss (i.e. total bets minus total wins).

For example, the offer might look like this: 10% cashback on roulette losses up to $50. In general, rebates are issued as real money rather than bonus cash because you’ll have already wagered a certain amount at Top Online Casino Bonuses September 2024.

10. Exclusive Bonuses

Exclusive casino bonuses are unique to an operator or affiliate. Here at Gambling.com we broker deals with the best US online casinos. These deals range from deposit bonuses worth more than the market average to extra free spins and special no deposit offers.

This means our exclusives are among the best casino bonuses for US customers. How do you unlock these deals? We give you links that activate a deposit casino bonus. We may also give you an exclusive deposit bonus code.

The Best Casino Bonuses Online Compared

Finding an online casino bonus isn’t that hard. A quick Google search will reveal a plethora of promotions. However, while it’s easy to find bonuses, it’s hard to decide which ones are worth taking. That’s where we come in. We’ve already explained how we broker exclusive deals with the best paying online casinos.

Our experts also test every casino bonus. This means we review the casino bonus terms and conditions. Only after we’ve carried out our review will we recommend a welcome bonus or ongoing offer. This means you can trust our recommendations listed in the table below to give you the best value possible.

How to Choose The Best Casino Bonus

OK, so that’s how to make money from casino bonuses. You know why online casinos offer bonuses. You know the type of deals you can get and how to get them. Before you go off and get more value for your time online, here are some points to remember:

1. Always find legit deals from licensed online casinos – The recommended casino bonus offers listed in this guide are all legit and offer the best value possible. Alternatively, you can grab a bonus at a social casino to play for fun. We recommend our Stake.us bonus code for this.
2. Look for low wagering conditions –Getting tons of bonus credits is great but only if you can unlock them. If the barriers to entry are high or the playthrough target is unreachable, an offer isn’t worth claiming. Therefore, you should only take deals that have suitable wagering requirements.
3. Understand your responsibilities – Check the terms before you start playing. Missing just one requirement can cause you to lose out on a bonus.
4. Look for bonus codes – We list all the best new casino promotions at Gambling.com and many of them require codes. So, if you want exclusive offers and the most value, use our promo codes whenever possible.
5. Have fun and don’t chase bonuses – Hunting for the best casino bonuses online is great, but you shouldn’t risk more than you can afford to lose just to get a reward.

Keep these points in mind the next time you’re searching for new online casino bonuses and you’ll be well on your way to getting maximum value each time you play at Top Online Casino Bonuses September 2024.

Casino Bonus Terms and Conditions

All promotions, from welcome bonus offers to free spins deals, have terms and conditions. These terms are known in the business as wagering requirements and they must be met if you want rewards.

To put it another way, if you don’t meet the wagering requirements before, during, and after you’ve claimed an offer, you won’t get your bonus. Before we run through the wagering requirements for the best USA casino bonuses, here’s a quick example of what to expect.

Casino A Bonus Offer: Get 50 free spins by depositing funds into your new online casino account. Minimum deposit $10, max cash payout $50. Playthrough is 5X the bonus amount and free spins expire in 10 days.

The wagering requirements for this offer are:

• The welcome package contains 50 free spins. Therefore, you need to be a first-time customer creating a new online casino account.
• Your initial deposit needs to be at least $10.
• The most you can win from your spins is $50.
• You can’t withdraw money while you have an active bonus. This means you need to bet 5X whatever bonus amount you win within 10 days.

That’s a basic example of how most bonuses work. It’s important to note that every casino bonus has its own specific wagering requirements. However, there are certain terms that are common across all promos. Based on this, here are the main wagering requirements you need to know when you’re learning how to take advantage of online casino bonuses at Top Online Casino Bonuses September 2024.

Minimum Qualifying Deposit

All deposit bonus offers have minimum deposit. In general, the minimum deposit for welcome bonuses is between $5 and $20. For reload offers, the minimum deposit casinos usually accept is $10-$20.

Deposit Methods

You won’t be able to claim some promo offers if you make deposits using certain payment processes. For example, some of our recommended New Jersey online casino bonuses stipulate that you can’t deposit using credit cards. If there’s a clause like this in place, you’ll forfeit your right to a bonus if you make a deposit with Visa, MasterCard etc. This rule applies to new player casino promotions, rewards you get via a loyalty program, and the biggest casino bonuses for existing customers. You can click the following link to learn about deposit bonus offers for PayPal casinos.

Casino Bonus Codes

Some of the best online casino promotions are only activated when you provide a code. In general, codes are used for online casino sign-up bonuses. For example, if you look through our top-rated PA casino bonuses, you’ll see that some brand’s welcome offer is only triggered when you input a particular promo code. If codes are required for casino sign-up offers, you’ll typically need to enter them during the registration process. Some online casinos want you to input the code before you make a deposit. Finally, you may need a code to claim ongoing offers, such as reload bonuses and rewards earned via a loyalty program. *Make sure you use our reviews to compare casino bonuses and see which deals require promo codes in your state.

Wagering Requirements/ Playthrough

There are terms and conditions (aka wagering requirements) attached to every offer. You need to follow these requirements before, during, and after claiming an online casino bonus. Some of the conditions you’ll need to consider once you’ve claimed a reward are…

Game Contributions

Bets on certain games count towards your playthrough target and some won’t. If all games count, then there will be different contribution weights. A contribution weighting refers to how much of each bet goes towards clearing a bonus. For example, if a game has a 100% contribution weighting, it means every cent you wager goes towards your playthrough target. If the weighting is 50%, half of anything you stake contributes to the playthrough. The best USA online casino bonuses give you credit for playing any casino game. Online slots are best when it comes to clearing a bonus amount because, in general, they have a 100% contribution weighting. Games such as blackjack and roulette typically have contribution weightings between 10% and 50%.

Time Limit

Not even the top casino bonuses last forever. There will come a point when an available offer expires. Additionally, you will have a limited amount of time to clear your bonus (i.e. hit the playthrough target). If you fail to complete the wagering requirements within the allotted time-frame (i.e. the playing period), you forfeit the total bonus amount. New casino bonuses tend to have longer playing periods because the operator wants as many people to sign up as possible. The same goes for sign-up casino bonuses. No wagering casino bonuses usually have the shortest playing periods. This is because you don’t have to make any deposits or bets to get them. Therefore, it makes sense to have short expiry dates.

Cap on Winnings

It would be nice if you could win an unlimited amount of money from bonuses but you can’t. There will almost always be a cap on the amount you can win using bonus credits, so take this into account before you start playing.

State Restrictions

The best NJ casino bonuses might not be the same as their counterparts in other states. Why? Because state laws govern what gambling sites can and can’t do. Therefore, the rules governing Michigan casino bonuses might be different from those in New Jersey and Pennsylvania. Our guides give you a complete overview of the gambling laws in all states where online casinos are legal. They also review what each operator offers based on local regulations. You can use the following links to learn about the best casino bonuses and promotions in New Jersey, Michigan, and Pennsylvania: New Jersey online casino bonuses Michigan casino bonuses PA casino bonuses

Game Restrictions

Playing certain casino games might prevent you from claiming and/or clearing bonuses. For example, there might be a clause that says bets on live dealer games won’t clear a bonus. Therefore, you need to check the terms and conditions before you start betting in order to avoid disappointment.

How to Calculate Casino Bonuses Online

Calculating bonus returns is fairly simple once you understand the basics. The following formulas should help you determine your potential returns for new customer offers, cashback and more.

1. Deposit Free Bonuses

Sign-up + Verification = Reward

No deposit bonuses aren’t dependent on a financial transaction. Therefore, the reward you receive is fixed. All you have to do is complete the steps required to unlock the reward.

2. Deposit Bonus

Deposit Amount + Deposit Bonus Multiplier = Reward

Let’s say you’ve scrolled through the best online casino new customer offers and chosen Caesars welcome bonus. As per the terms, you get a 100% deposit match up to $2,500. In this context, 100% means 100% of the deposit’s value. If the multiplier was 50% it would pay out a bonus worth half the value of your deposit. If you deposit $250 with a 100% bonus, you get the following:

$250 + 100% multiplier = $250 bonus + $250 real money balance (total account balance of $500)

3. Free Spins Bonus

Action + Free Spin Bonus = Reward

Like no deposit bonuses, free spins rewards are fixed. Therefore, all you have to do is complete the required action and a bonus will be unlocked.

4. Cashback Bonus

Wager – Wins + Cashback % = Reward

Cashback bonus offers give you a percentage of your net losses back. This means you have to work out your net loss, then take a percentage of it as your reward.

Net loss = total wagered – total won

If you wagered $500 and won $300, your net loss would be $500 – $300 = $200 net loss. Once you’ve got this figure, you apply the cashback percentage.

Net loss X Cashback %

Let’s say the cashback offer is 10%. Divide 10 by 100 to get 0.1. You then do $200 X 0.1 = $20. So, in this example, you’d receive $20 cashback.

5. Loyalty Rewards

Action + Points = Rewards

The best loyalty program bonuses are unlocked by points. These points are earned by placing real-money bets. Each online casino has its own points system, but we’ll use Caesars Rewards as an example:

• $10 wagered on video, progressive, or classic slots gets you one point
• $25 wagered on video poker gets you one point
• $50 wagered on blackjack gets you one point
• $25 wagered on all other casino games gets you one point

Accruing these points contributes to your VIP status which, in turn, unlocks rewards. Additionally, you can convert points to bonus cash. All top-rated casino rewards programs operate in a similar way, so you should be able to calculate your potential returns based on the points scoring system.
