Online casino promotions & bonus types

Welcome Bonus (First Deposit Bonus)

Of the best online casino bonuses, the most well-known is the Welcome Bonus. It is the bonus that you get right when you sign-up and deposit on an online casino. This is why it is also known as the Sign-up bonus. The first bonus you will get. It helps you start with a healthy bankroll and motivate you at the beginning.
On most of the top US online casino sites, the initial bonus matches the deposit amount in a different percentage (50-200% usually) and up to a certain amount ($2000 usually). To get the maximum bonus, deposit the maximum deposit match.
You should check the conditions of the particular online casino you have chosen and check the wagering requirements before you deposit.
There is usually a minimum deposit required, but it is often as little as $10.
The match deposit bonus is considered one of the top casino bonuses and attracts a lot of attention.

No-Deposit Bonus

There are multiple no-deposit bonuses. The idea is simple, start playing without making any initial deposit. But you don’t simply receive free money. You get a chance to play with a free amount of between $10 and $50. You need to play with this money until you reach the WR. Before that, you can’t withdraw it. The types of the No-Deposit Bonus are:

  • No-deposit Free Spins. The Free Spins bonus is for video slots and other slot games. You will get a certain number of tries on the slot machines and get free spins winnings.
  • No-Deposit Free Playing Credits. With this bonus, you get free credits to play. It can apply to a particular game, games, or the whole online casino. You need to check the terms and conditions to be sure for which games it applies.
  • No-Deposit Free Bets. Free Bets bonus can be used on online sports betting sites and online gambling sites. The idea is simple. You can make limited free bets and get rewards.
  • No-Deposit Bonus Cash. The No-Deposit Bonus Cash adds additional free money to your bankroll. The money will have conditions, but you will be able to use it to play. You need to play multiple games until you can cash in the money to your wallet.

Reload Bonus

The Reload Bonuses are for those players that already have an account on the online casino. They are a type of Deposit Bonus. When you deposit again into your account, you get an additional percentage (10-100% usually) and up to a particular amount as a bonus. The Reload Bonuses are smaller than the initial bonuses. The other difference is that you might need to deposit on a particular day when the promotion applies.

The Reload Bonus is the best online casino bonus for regular players. So, if you play a lot on a certain online casino, check out this kind of casino promotion.

Mobile Bonus

On your mobile, you can get most of the bonuses, just like on the online casino. When we talk about a mobile bonus, we refer to a specific bonus that you can claim through your mobile. The mobile bonus can be exclusive to mobile users, or it can be the same as on the online casino site.

Cashbacks and Cash Rebates

The Cashbacks or Rebate Bonuses give you back a percentage of your lost. An extra cash that you can use to play again. They are usually given to people, who are losing more, than winning. The percentage is not high. The best possible is around 10% of your total losses. If you are not a lucky player, you should most definitely take advantage of Cashbacks and Cash Rebates bonuses. Not all sites have these bonuses, but you can find them on the top online casinos.

Crypto Bonuses

Cryptocurrencies, especially Bitcoin and Ethereum, have become extremely popular in America. The casinos have taken notes, and many of them allow you to bet with cryptocurrency. You need to deposit cryptocurrency into your casino bankroll, and you get an additional Crypto Bonus. It is a type of Deposit bonus. Often the Crypto Bonuses can add more to your account, but usually, they have higher wagering requirements.

For some a Crypto bonus can be the best online casino bonus USA, for others the digital currency is just too complicated.

Daily Bonuses

Online casinos and mobile casinos want you on their platforms all the time, so they try everything to make you visit often. The Daily Bonuses are such a tool to make you visit their platform daily. They are deposit casino bonuses and can be like a “Happy Hour” promotion, which gives you an extra bonus at a specific time, or they can be a simple free spins promotion.

VIP & Loyalty Rewards

Many of the best online casinos offer loyalty programs for their players. Such a Loyalty Program or VIP program brings rewards to those players that play more on the site.

The loyalty rewards can be related to the deposits you make or to the times you have played games on the site. Usually, you collect points and level up. When your rank gets higher, you get better loyalty rewards, which can include bonuses, free credits, exclusive casino tournaments, contests of different sorts, birthday gifts, and even faster payouts.

Each casino is trying to keep you as a regular user, and it is willing to give extra perks. There is a lot of competition, so it is really common to have a Loyalty or VIP program.

Refer-a-Friend Bonus

Refer-a-Friend Bonus or Friend referral is an affiliate marketing tool that will get you additional bonuses for every “friend” that you bring to the online casino. The casino will provide you a link, and everybody who register through it, and deposits, will bring you a Refer-a-Friend bonus.

The bonus can be a percentage of the deposit the person puts into his or her account, or it could be a flat rate like $50, $100, or $200.

There is usually no limit to how many people you refer, so if you have some influence, you can bring a decent amount of bonus money to your casino bankroll.

Tournament & Contests

There are many competitor games on online casinos. You can find Poker, Blackjack, Roulette, and more, where you play against other players. Online gambling sites often organize game tournaments and different contests. You can enter and play for big prizes.

So, there are many casino bonuses and promotions. The sites will do everything to keep you playing on their platform. Try to take advantage of as many as you can bonuses. Check their latest casino bonuses and often read the terms and conditions. You are playing real money casino games, so every extra bonus can come in handy.

How do you calculate the value of a casino bonus?

You came here to collect online casino bonuses, not to do the math, right? So, we will make it as easy as possible for you. The biggest bonus that you should check is the so-called welcome bonus. It is a deposit match bonus up to a particular amount. Here you have some examples.

If you have a 100% deposit match bonus up to $1000 and you:

  1. Deposit $100, you will get a $100 deposit match bonus, and you will have $200 in your casino account in total.
  2. Deposit $1000, you will get a $1000 deposit match bonus, and you will have $2000 in your casino account in total.
  3. Deposit $1500, you will get a $1000 deposit match bonus, and you will have $2500 in your casino account in total. The match bonus is up to $1000, so you won’t get any additional free money to play. To get the most out of such a match bonus, you should not deposit more than the maximum it offers to match because you don’t get any additional benefits.

This money is the amount you will have in your new casino account. It is the money you can use to play on that casino site. You can’t directly withdraw it and make a quick buck. You will need to play with the money a particular number of times, based on the conditions of the online casino.

For the bonus offers, you must check the Wagering Requirements or (WR).

What are wagering requirements (WR)?

The Wagering Requirements (WR) are the most important aspect of the terms and conditions of the bonus offers of most casinos. It is the amount of money you need to gamble before you can withdraw the money into your wallet.

The WR will depend on the deposit amount, and the bonus received.

Without understanding it, you can’t choose which is the best online casino bonus USA for you.

Game contributions

The essential thing is that different games will contribute different percentages to your wagering requirements, and each online casino has its own game contributions. Popular casino games like slots almost always have a game contribution of 100% because you have lower chances to win.

On other games, typically table games like poker, craps, and baccarat, the game contribution can be as little as 20%. That means that you need to bet 5x more than on slots to get the same WR.

The best online casino bonuses include multiple games with different game contributions that count toward the WR. That gives you a wide variety of opportunities. You can choose the game that you like the most or a game that you are truly good at but with lower wagering requirements.

$10 on slots
100%

If you bet $10, with a game contribution toward the WR, it will count as10$. Here, you don’t have any surprises.

$10 on poker
20%

If you bet $10 on a poker game that has a 20% game contribution towards the WR, that translates into $2 towards the WR. Why? Because 20% of 10$ is $2.

$10 on slots
$10 on poker
100%
20%

If you bet $10, with a 100% game contribution toward the WR, it will count as 10$. The second bet, $10 on a poker game that has a 20% game contribution towards the WR, that translates into $2 towards the WR.
In total, you have bet $10+$10=$20. But only $12 count toward the WR. Pay attention to this, so you don’t get confused.

Eligible games

The eligible games are those that the online casinos count towards the clearing of your bonus. Many times, not all of the games that are available on a gambling site or gambling application are eligible games for clearing your bonuses.

Almost on all platforms, the slots are eligible games and usually count with 100% game contributions. Other popular table games usually are included too, but with lower game contributions.

The games with a progressive jackpot will be restricted. But you can play on them with your own money, after you deposit.

Winnings limits

In the USA, there are no winnings limits yet. On some other markets, such winning limits exist, so you can be glad that you are playing in the US!

Imagine if you have a winnings limits of 2x or 5x your deposit. That could be extremely sad if you won a big jackpot.

But the American players, playing in their country, don’t have such limitations! Enjoy!

Typical expiration times of bonuses
Welcome bonus14-30 days
Free spins3-7 days
No-deposit bonus3-14 days
Reload bonus14-30 days
Other promotions7-30 days

Expiration time

Most of the casino bonuses are available for a limited time only. For example, if you have just read our BetMGM casino review and have signed up and entered your first deposit, the expiration timer of the initial bonus will be activated.

Don’t just get the bonus and forget it. You should play as soon as possible, so you don’t lose it. Yes, you often have 14 days and more, but the time passes quickly, and you can forget it. At least try to use as much as possible the bonus, during the first few days. After that, even if you still have some amount, it will be easier to pla y it. You better use the complete bonus amount because it is a free opportunity. Especially the sign-in bonus because you can only get it once.

Also, don’t waste the free spins. Maybe slot machines are not your favorite game, but you can still get money. And later, you can use the money for the games you prefer.

What games can I use my bonus on?

Online casino bonuses are typically playable on all types of online casino games for real money. But there is a catch. Not all of the games contribute the same towards clearing your bonus. Some contribute more than the rest, so you need to read the terms and conditions of each casino just to know better.

Usually, games where the casino has an edge (bigger advantage), like Slots and The Wheel of Fortune, contribute 100% towards clearing the bonus.

The games that contribute less are most of the table games like online poker, online baccarat, online blackjack, and more. Basically, if the casino has less of an edge against you as a player, then it is possible that those games contribute less towards clearing your bonus.

How to redeem a casino bonus?

There are 3 steps that you need to take to redeem your casino bonus.

  1. Register an account. The first step is to register on the gambling site you have chosen. If you haven’t checked casinos yet, you can see our Casino reviews page.
  2. Go to the Cashier. If you haven’t chosen a no-deposit bonus, then you need to deposit to receive your bonus. When you do it, you will get a deposit match bonus equal to the deposited money, up to a particular amount. In some sites, you need to enter a bonus code to redeem it.
  3. Play. You already have your deposit + bonus in your account. Go ahead and play! Enjoy the thousands of games that the online casino offers. Hopefully, you get lucky, and later, when you cover the WR, you can withdraw your earnings.

What are casino bonus codes?

Casino bonus codes are just the method online gambling sites use to offer you bonuses. The offers that you see from the casinos require you to add a bonus code to get the benefit from it.

There are some sites that automatically activate your bonuses without the need for bonus codes. It differs from site to site.

If, for some reason, you didn’t get the promised bonus, go ahead, and contact the customer service of the casino you have chosen. They will help solve your problem, and you will redeem the bonus.

Top tips for spotting the best online casino bonuses

Online casinos have plenty of offers, and they don’t end with deposit bonuses. There are free spins, reload bonuses, cashback bonuses, and loyalty programs. In the sea of available bonuses, how to find the best offers? Check the following information first.

  1. Start with our list at the beginning of this page

    We have already selected the best bonuses and offers in the USA. After long research and reviews, we have already discarded the fake casino bonuses, compared the rest, and organized them in a table for you.

  2. How generous is the Welcome Bonus?

    The Welcome bonus is really one of the top bonuses an online casino can offer. Check how much of your initial deposit the casino can match. Thanks to the huge competition between them, the deposit match bonus is 100% almost in all online casinos in the USA. But each casino matches it until a different amount. The average amount for the matching is set to $2000.

    What you can also benefit from is an increased welcome bonus if you play with Bitcoin or another cryptocurrency.

    And sometimes, you can also get an additional no-deposit bonus or free spins upon registering an account.

  3. Read the terms and conditions

    To learn everything there is about bonuses, you must read the Terms and Conditions. Check well the contributions each game offers towards the clearance of your bonus. Be sure that you understand what the WRs are. Also, take note of the bonus expiration date if there is such. You don’t want to lose money just because you didn’t play on time.

    Many times, the bonuses can be used only on specific games. Check if those games are interesting for you.

    And lastly, don’t forget to check how you can withdraw your money from the online gambling account to your bank account. How much time will it take, and are there some additional fees? Usually, the withdrawal is not instant, and it will take at least a few business days. There will be a small fee too.

  4. Look beyond the welcome bonus

    Yes, the welcome bonuses are those that first catch your attention, but they are not everything.

    The plan is to start playing and enjoy the online casino for a long time. This is why you need to check if the casino has a loyalty program for those who have played for a long time.

    There are also weekly deposit bonuses, many free spins bonuses, and new seasonal bonuses.

    Now that you already know how to spot a great casino bonus go ahead and try your new skills. Browse the best online casino bonuses and find those that are right for you. Enjoy the additional free money to play, but be sure that you understand the conditions. That way, you won’t feel cheated in any way, and you can dedicate yourself to having fun and potentially winning some money.

How can I make sure the casino bonus is not a scam?

You have a good reason to be concerned. There are many scams on the Internet, and Phishing scams, those that make you click and use your information illegally, are incredibly popular.

So, to check if a casino bonus is real, first, you need to verify the casino itself. You can do it by checking if the casino has a US license. Check if it is registered in the state, that it says on their site.

If it is unlicensed, don’t continue any further. It could be a scam, or it could be an illegal casino. Both should be avoided, so you don’t have any trouble. Check also if the online gambling site has the necessary security to handle your data. Look at the address bar and check if the site works with HTTPS (look for a padlock icon).

After verifying the site, you can go ahead and read the Terms and Conditions of the casino site. There you can find the details about the bonus and the WR.

Now that you know all the conditions, do they match your expectations? If that is the case, the bonus is not a scam, and you can continue by depositing and playing. If not, then go ahead and check another casino site. Here we have plenty of great offers!

Can I withdraw my casino bonus?

Yes, you can withdraw your casino bonus, but after you fulfil the requirements established in the Terms and Conditions. Check the WR for the specific bonus. It establishes how many games you need to play, with what wager, and if there is any time limit.

When you bet enough on games, you can withdraw the money that you have in the end.

Choose your preferred payment method for receiving money, and go ask for your winnings. You will need to wait a few days until the money gets into your bank account.

Pros and cons of casino bonuses

  • The bonuses extend your playtime.
  • They give you a bigger chance to win.

Online casino bonuses FAQ

Why do some people recommend avoiding casino bonuses?

Some recommend avoiding casino bonuses because they find the Terms and Conditions too challenging to follow. Sometimes the WR (Wager Requirements) are hard to reach, and there is even an expiration period for the bonuses. That can make it very difficult for some people, and they prefer to ignore the bonuses and don’t recommend them.

Why do online casinos offer promotions and bonuses?

The online casino scene in the USA is very crowded, so the casinos have to dedicate substantial sums to marketing. They offer new bonuses and promotions to attract new customers.

The bonuses should be competitive compared to the rest of the sites.

Apart from that, the casino sites need to keep the current players on their platforms. Here come the rest of the bonuses, like reload bonuses, cash backs, competitions, and more.

Are these promotions offered to new players only?

No. There are some promotions for new players, like no-deposit bonuses and welcome bonuses, but there are many others for old users. The players who have already played on a mobile app or a site can enjoy casino VIP programs, additional bonuses, enter tournaments, and even get cashback if they lose money. So, there are always different bonuses and promotions to keep the players happy.

How long does it take for these bonuses to hit my account?

On almost all online casinos, just after you deposit or add the bonus code, you will get your bonus in your bankroll. That way, you can start playing right away with the full amount of your account (deposit + bonus). If, for some reason, you are not getting your bonus on time, contact the site’s customer service, and they should resolve the issue.

Are the biggest casino bonuses really the best casino bonuses?

No. Many times the biggest casino bonuses, like +500% match deposit bonuses, have far more conditions and higher wagering requirements (+40x). That obligates you to play far more games until you can claim your deposit bonus and withdraw your earnings. You can also face an expiring bonus period that will push you to play fast, and that could be less enjoyable. Often, a more modest bonus, say a 100% deposit match with WR of 10x, will be a far better choice. So, the best casino bonuses are not always the biggest.

How do I claim a casino bonus?

You will either get a bonus code that you can enter during your first deposit or a drop-down menu with applicable bonuses that you can select from.

In rare cases, the bonuses apply automatically without needing to do anything. Please read carefully the information about the bonus you would like to claim before you start, or you might not get it. In any case of a problem, contact the casino’s customer service.

What is the best kind of casino bonus?

The Welcome Bonuses are probably the best kind of casino bonuses. They match your deposit and give you a big additional sum to bet on your games. Yes, they have conditions, but talking about bonuses, they are the top online casino bonuses. But the best bonuses for you could be different. You should also think about your gaming style and game preferences.

What casino games can I use my bonuses for?

On some sites, you can use your bonuses on all of the games. On others, only on specific games like the free spins are only for online slots. And on the third type of sites, you can use them on a limited number of games and with different game contributions. The terms and conditions are not the same on all sites, so you need to check carefully.

Are all bonuses subject to wagering, playthrough, or rollover requirements?

No, not all available bonuses are subject to wagering, playthrough, or rollover requirement, but most are.

Some of the bonuses that are usually not subject of such conditions are the Cash Rebates that you get based on your losses. It is an incentive that has the goal of motivating you to continue playing and gamble some more money.

Why do casinos offer larger bonuses for cryptocurrency deposits?

Crypto bonuses are one of the largest Welcome Bonuses that casinos offer. This is because transferring crypto from your crypto wallet to your gambling account is really easy and fast. The casinos like this because it is instant. They also like that with crypto, you can import big amounts of money at a time. The more money you have in your bankroll, the bigger bets you can make. Just don’t forget that the biggest bonuses come with the biggest WR!

Do online casino bonuses expire?

Yes. Most online casino bonuses expire, and you will have 7, 14, or 30 days to claim and use your bonus. The casinos want to play right away and don’t leave their site. Therefore, they obligate you to use your bonuses in a defined period.

Can I withdraw my casino bonus?

You can withdraw your bonus, but after you clear it. To clear it, you must follow the conditions of the Wagering Requirements. You will need to play a certain number of games with a certain total amount of money played. After you achieve it, you can withdraw what is left.

What makes a good bonus?

It depends on you and your game preferences. A good bonus is easy to understand, has appropriate conditions, provides a generous amount of money, credits to play, or free spins, and can be claimed easily.

Are online casino bonuses worth it?

Yes, online casino bonuses are worth it. You get additional resources, money, game credits, free spins, and more. If you don’t claim it, you will directly lose an opportunity. After you claim the bonuses, you can think and see if they fit your game style, but it doesn’t hurt to get them.

Are the bonuses available for mobile play?

Yes, they are available for mobile play. Mobile casinos often offer additional bonuses or higher bonuses for players who prefer to play on their smartphones. You can get additional perks like no-deposit bonuses or free spins for mobile slots.

Are there additional online casino bonus conditions to check out?

You need to read all the Terms and Conditions carefully. You need to be aware of the Wagering Requirements, the Game Contributions, the Eligible Games, The Winning Limits, and the Expiration Time. Knowing all of them will help you evaluate the online casino bonus and see if it is right for you.
