Most bonuses come with strings attached. Remember to check out the terms and conditions to avoid surprises.

There are also more bonus types aimed at different players. Casinos hand these out at different stages of your player journey.

Different types of casino bonuses

Online casino bonuses

First, you need to understand the difference between deposit and no deposit casino bonuses:

These are the main types of bonuses available in US-licensed online casinos:

In addition, you need to consider these things while choosing a bonus:

Below, we'll look at these factors in more detail.

Deposit match bonus

The deposit bonus is the basic type of casino bonus. They give you an extra boost when you deposit money at an online casino. Terms and conditions do apply, but they're usually less restrictive than with no deposit bonuses.



EXAMPLE 1: The casino offers a 100% deposit bonus of up to $100. You make a deposit of $100, getting another 100 dollars as bonus funds. This means you'll have a total of 200 dollars on your account.

EXAMPLE 2: The offer is the same as in the first example. You deposit $200, which exceeds the maximum of the bonus offer. You still get the maximum bonus, meaning that you'll have $200 cash, plus 100 dollars of bonus funds on your account.


A deposit bonus is a great option when you've found a casino you like and are ready to put some money on the table.

Pay attention to the fine print. When you choose your bonus well, it will give you another chance to win if your real money balance runs out.

No deposit bonuses are a great way to check out the casino before putting your own money down. However, the casino is essentially giving away free bonuses, so the terms and conditions are quite strict.


  • No need to risk your own money
  • You only need to create an account
  • Chance to win real money


  • Low monetary value
  • High playthrough requirements
  • Maximum wins capped
  • You need to confirm a banking method to withdraw winnings, i.e. make a deposit

EXAMPLE: A casino offers $20 as a no deposit bonus. After you've successfully created an account, you can claim the offer and have the 20 bucks to play with.


No deposit bonuses are a free sample of what the casino has to offer. However, the low bonus value and difficult bonus terms mean it's unlikely to have enough winnings left to withdraw anything.

Free spins are complimentary rounds in popular slots. You get a set number of spins in a prespecified game.

Free spins can be either the entire bonus (e.g. the no deposit bonus) or just a part of it (on top of your deposit match bonus).

These spins are free in the sense that the bets aren't deducted from your cash or bonus funds.

The winnings are paid out in either bonus money or real cash that hasn't got any strings attached.

EXAMPLE: You get 10 free spins in Starburst. Each spin is worth 10¢. During your 10 spins, you win a total of $2. Before you can withdraw this sum, you have to complete the playthrough requirements.

Read more about free spins

Cashback is a very straightforward and fair bonus type. Cashback bonuses give you back a percentage of your net losses.

EXAMPLE: A casino offers a 5% cashback bonus. You play through your initial deposit of $100 without winning anything. The casino gives you $5 (5% of $100) as a cashback bonus.

Cashback bonus T&Cs may include time limits, wagering requirements, and maximum bonus caps. However, cashback is usually given as wager-free cash with no strings attached.

Is it bonus funds or cash?

In the USA, casino bonuses can be either bonus funds or cash. When you play with bonus money at a casino, you have to follow the bonus terms and conditions. If you break these rules, you risk losing your bonus.

Cash has no such restrictions. You can play any game you like with any bet you can afford, or withdraw your remaining balance at will.

Obviously, cash is the more desirable casino gambling bonus option. However, casinos don't like to hand out free money with no strings attached. That's why online casino real money bonus deals aren't widely available.

Turn your bonus money into cash by completing the playthrough requirements. After that, you can use the remaining balance as you please.

EXAMPLE: You have claimed a bonus offer and have $20 as bonus funds. The bonus terms specify that the player has to play through the bonus 25x, meaning you need to place bets worth $500 with the received bonus.

Different bonuses for different players

Not every gambler likes the same things. This is obvious when it comes to games, but it also matters when it comes to bonuses. Certain bonus offers suit certain types of players better.

Here are some of the most common types of players and the bonuses those players might want to take a look at.

Average Joe

Average Joe is a player who just likes to play but doesn't have a real preference. Maybe a spin on a slot here, a round of blackjack there. You enjoy winning, but also the entertainment factor.

For the average Joe, a regular deposit bonus works best. You get to try different kinds of games and enjoy the variety.


The optimizer is the player who is out for blood. You want to play the game that gives you the best chance of winning. You want the best value, the best return on your deposit and to always stay on top.

For the optimizers, a no deposit bonus is the best one out there. There is nothing to lose and you can only win, which is the optimal situation. The second option is a low or no wagering bonus. They have theoretically the best calculated value.

Sunday Spinner

Sunday spinners are a more casual bunch. You enjoy the games for what they are, games. Spinning a slot is fun, so why not spin a few rounds more? It's not so much about winning, but having fun.

The best casino bonus for a Sunday spinner is the free spin bonus. You can get a lot of spins for a small deposit. The bonus terms might not be the best, but at least you get to play more and have fun.

High Roller

The High roller doesn't play around with small stuff. Everything is big in a high roller's world, including the deposits, the wagers, and of course, the wins.

For high rollers, there is only one bonus, a high roller bonus. They are deposit bonuses that give you a huge amount of bonus money with a great percentage. The catch is that they also have a big minimum deposit, which is why regular players don't take them.

Find the best bonuses

What affects your deposit match bonus?

Deposit bonus offers vary a lot from one casino to the next. They might have the same basic idea, but there are some key differences. Knowing what to look for and what is best for you is important. A big flashy number might look enticing, but actually, be completely pointless.

The three big questions about bonuses are:

Knowing how to answer these questions will make choosing a bonus child's play. Below, you can find what they actually mean.

Welcome packages

Best online casino bonus package

When you sign up to a casino and make your first deposit, you have the option to accept a bonus. Some casinos have only one new player bonus; others let you choose between different options and some give you multiple bonuses one after the other. Many also offer a no deposit bonus upon sign-up.

The best value online casino bonuses can usually be found in the new player bonus package. These welcome bonuses are usually broken down into a few subsequent deposits. They all feature different bonus sums and percentages. Some also come with free spins.

On Bojoko, the casino listings feature a breakdown of the welcome bonus packages. You can easily check out what the casino has in store for you after your initial deposit.

EXAMPLE: A typical new player welcome bonus package may include:

This may sound appealing, but you need to pay attention to the bonus percentages. If you're taking full advantage of any casino's welcome package, you're going to deposit much more than you're getting back in bonuses.

Although the example package amounts to a total of $1,000 + 100 free spins, you'd have to deposit $3,100 to get the maximum bonus. How? It all boils down to bonus percentages, which we cover below.

100%, 200%, 300%, 400% and 500% - How important is the bonus percentage?

The bonus percentage determines how much bonus money you get compared to your deposit, or in other words, how valuable it is. The bigger the bonus percentage, the less money you have to deposit to get the same amount of bonus.

Most online casinos offer 100% deposit match bonuses. However, the bonus percentage can go up to several hundred.

Here's how different bonus percentages work in practice, with the example deposit of $10:

Many sites use the total balance in their ads. For example, you may see "deposit $20, play with $60". This may sound more appealing to the player. At the same, it blurs the line between your real money balance and the bonus funds.

As we explained in the section above, the bonus funds are separate from your real money balance. You get to use the bonus funds only after your real money balance is gone. You're not playing with $60 at once; you first play with $20 of real money and then with $40 of bonus. With real money, you can do as you please. However, the bonus funds may be subject to wagering requirements.

We have created quick filters for different bonus percentages. Return to our bonus list and discover welcome bonuses of 200% or more.

25% and 50% reload bonuses

With the first deposit bonuses, the bonus percentages are usually measured in hundreds. After that, most casinos get a little stingy. You've created an account, verified your info, and registered a deposit method… you're not going anywhere, right?

Subsequent bonuses are known as "reload bonuses" in the casino lingo. The bonus percentages for later deposits are usually in the 25% to 50% region. With a 25% deposit, the casino only gives you $1 for every $4 deposited. At a glance, a $200 casino bonus at 25% might look nice in a long list of bonuses, but in reality, it's not.

To be honest, this isn't a great deal, especially compared to the massive first deposit bonuses. However, if you change casinos more often than socks, sooner or later you'll run out of great places to play.

With that in mind, consider what you want to get out of bonuses. Bonuses are supposed to be an extra incentive to try out a casino and to reward active players. They're supposed to be a spice, not the main ingredient of the casino experience. If you expect to gain an advantage over the casino by using bonuses, you're in for a nasty surprise.

Bonus sums

Casino bonuses feature the maximum bonus sum. On Bojoko, we list bonuses in the format bonus percentage/bonus sum, e.g. 100%/$100. The casino will match your deposit with bonus money up to this sum.

Beyond that sum, you won't get any extra benefit from making a bigger single deposit. If your deposit sum goes over the maximum bonus limit, it may be better to split the deposit. You may get some extra goodies for the portion that would have otherwise been left unmatched.

You'll see the maximum bonus sum in the casino listings and our selection tool.

High roller bonuses

A high roller is a person who likes to deposit big and play with huge bets. Standard casino bonuses may seem too low for them. Luckily, some sites feature bigger casino bonuses for them.

High roller bonuses are often massive and have high bonus percentages. They are the biggest deposit bonus available. Unfortunately, they also have a high minimum deposit usually in the hundreds of dollars range.

We have listed the highest welcome bonuses available for US players. You can see them by clicking the Highroller bonuses quick filter on our casino bonus list. It shows $500 bonus casino offers and bigger.

What makes a bonus the best?

Best US casino bonus

Every casino keeps saying that they have the best bonuses, but what exactly makes a bonus the best? Sure, everyone can see if you have the biggest online casino bonuses available, but that number alone doesn't make a bonus the best.

Bonus terms can play a much bigger role than the actual bonus the casino is offering. You can read more about bonus terms and learn what requirements and restrictions are commonly used.

Check the bonus type you like and see what the casinos have written in the fine print.

Best deposit bonus

Deposit bonuses are common stuff and they are sold in big numbers. The amount of bonus money isn't the only thing you should be looking at.

The best deposit bonus is the one that has a large sum of bonus money available, a big bonus percentage, and a decent playthrough requirement. If any single leg is weak, the bonus offer will fall. Then you either don't get much, have to deposit a lot to get it or you are going to have a hard time withdrawing it.

Best no deposit bonus

No deposit bonuses are always great, because you don't have to deposit to get them. Unfortunately, they have a lot of small print attached.

The best no deposit bonus is the one that gives you free bonus money with easy terms. No winning caps and a decent playthrough requirement are the makings of a great bonus offer. A quick check of the bonus terms will tell you if the offer is actually the best.

Best free spins

Playing slots for free is fun and the chance of getting real money out of them makes these bonuses enticing. The more spins, the better the bonus, right?

Free spin offers are generally easy to tell whether they are good or not. It's all in terms and limitations. 100 spins is always 100 spins, but if the bonus has a winning cap, it can't be the best free spin bonus. You should also check the playthrough requirement just like with deposit bonuses.

Best no playthrough bonus

A bonus offer where you don't need to wager sounds great as it is. These no playthrough bonuses are good, even if their other terms might be tough. 

What to look for in the best no playthrough bonuses are the other terms. Sure, the bigger the bonus, the better it is, but you need to check if it has any winning caps or other limitations.

Casino bonus terms and conditions

Practically all online casino gambling bonus deals come with some strings attached. The idea is to guide players to use the bonus on casino games and limit the risk to the casinos.

Every casino and every bonus type has its own specific terms. Here's a quick overview of the terms and conditions you may encounter:

This may sound confusing and intimidating. However, we want you to be a well-informed player who's ready for everything. Do your homework and avoid any unpleasant surprises.

Wagering requirements

Wagering requirements tell you how much you need to bet before the bonus funds become real money and can be withdrawn. They're also known as playthrough or bonus rollover.

The wagering requirement is expressed as a multiplier of the bonus sum, e.g. 35x (B). However, it may also apply to your deposit (D) or both (D+B).

In most cases, wagering only begins when your real money deposit and winnings run out and you start to play with bonus funds. Even though you have only the bonus funds to complete the wagering, you may need to bet the total sum of your deposit and bonus multiplied by 30 or more.

Rule of thumb: Any wagering requirement over 35x (B) is hard to complete.

A high bonus percentage usually goes hand-in-hand with high wagering requirements.

Minimum deposits

All casinos have a minimum deposit limit. Because handling money transfers and onboarding new players aren't free, casinos try to incentivize players to deposit more on one go.

However, the casino's minimum deposit may not qualify you for the bonus.

EXAMPLE: The casino's minimum deposit is $10 but the minimum qualifying deposit for the bonus is $20. If you only deposit $10, you can play the games with real money but you won't get the bonus.

Excluded banking methods

Most casinos have a long list of supported deposit and withdrawal methods. However, your options for the first deposit are more limited.

Many casinos routinely exclude e-wallets like Skrill and Neteller from bonuses. Also, PaysafeCard is occasionally on the exclusion list.

This may be down to KYC procedures but mostly for safety concerns. Since e-wallets provide a degree of anonymity, some casinos would rather play it safe and exclude them.

Online gambling regulators work to ensure that casino operators aren't used for fraud or money laundering. They're not the biggest fans of the methods listed above: the chances of fraud and money laundering increase twofold with e-wallets.

Neteller and Skrill are often connected to bonus abuse. Players try to exploit loopholes in the terms and conditions to increase their chance of making a profit.

Additionally, e-wallets have some of the highest fees among deposit methods. This makes them both costly and risky for operators when they are offering a bonus.

Maximum bets

The maximum bet is the biggest bet allowed on a single spin while you're wagering your bonus.

For most deposit bonuses, the maximum bet is $5. Some casinos also have limitations for bet per payline and the max bet compared to the deposit.

Check the T&Cs to be sure.

Time limits

Deposit bonuses are only valid for a certain time. Once you make a deposit and claim your bonus, you only have a limited time to complete the wagering.

The wagering only starts after your real money balance is depleted, but the clock starts when you accept the bonus. However, you usually have a week or even a month or two to complete the playthroughs.

Check the expiration time so you don't accidentally miss your bonus.

Restricted games

While wagering your bonus money, your game options at a casino are somewhat limited. Although you can play most slots, some high-RTP game types don't get you closer to completing the playthroughs.

Casinos have three mechanisms to restrict the games:

  • Banned - Playing these games breaches the T&Cs and voids the bonus
  • Non-contributing - You can play these games, but it doesn't count as wagering
  • Partially contributing - The bets placed in these games only count as part of their value

EXAMPLE: Playing live dealer blackjack contributes 10% towards wagering. Every $10 bet counts as $1 in wagering.

Bonus caps

Many bonuses have so-called "maximum conversion", also known as the bonus cap. This is the maximum sum you can win and withdraw from a certain bonus. Everything above that is confiscated.

EXAMPLE: You get a $50 bonus and the maximum win is capped at $250. After completing the wagering, you have $350. You can only withdraw the $250, the casino keeps the rest.

Minimum withdrawals

As with deposits, also handling withdrawals costs the casinos money. Besides, they'd rather see you playing that money instead of taking it home just yet. That's why casinos have a minimum withdrawal limit.

You have the right to withdraw your real money balance at any time. However, if your withdrawal is below the minimum threshold, the casino can charge additional handling fees. These can be several dollars, which makes the fees swallow up a large portion of your withdrawal.

Deposit to confirm a banking method

This rule is relevant to no-deposit bonuses.

You can win real money without risking your own. Unfortunately, you can't get it out of the casino without making a deposit.

Casinos need to satisfy anti-money laundering (AML) and Know Your Customer (KYC) rules. That's why they need you to verify a banking method for withdrawals. This happens by making a deposit and playing through it one more time.

The banking method needs to be one that supports withdrawals. That's why many pay by mobile phone methods are off the table.

There's really no way around this step. All you can do is pick a casino with a low minimum deposit.

Calculate the value of your bonus

When comparing bonuses, there are two main goals:

  1. Get the biggest bonus with the smallest deposit
  2. Complete the wagering and withdraw a big portion of the bonus

Often, these are mutually exclusive. As the bonus sum and the bonus percentage grow, so do the wagering requirements. These in turn hurt your chances of withdrawing.

This is what you need to know to calculate the expected value of a bonus:

Here's how you calculate what you will have left after completing the wagering. It's a bit tricky, so let's break it down into five steps:

  1. Bonus sum = Your deposit x the bonus percentage
  2. Total sum to be wagered = Your bonus sum x wagering requirements
  3. Expected loss = Total sum to be wagered x (1 - RTP)
  4. Expected value = Expected reward - expected loss
  5. "Return on investment" = Expected value ÷ original deposit

EXAMPLE: You get a 100% bonus up to $100. The wagering requirement is 30x (B) and the highest RTP allowed is 97%:

  1. Bonus sum = 100% x $100 = $100
  2. Total sum to be wagered = $100 x 30 = $3,000
  3. Expected loss = $3,000 x (1 - 0.97) = $90
  4. Expected value = $100 - $90 = $10
  5. "Return on investment" = $10 ÷ $100 = 0.1 = 10%

Why is the "return on investment" in quotes? You can calculate how much value you get compared to the money you put down. However, you shouldn't consider the money spent on gambling an investment. Besides, the bonus money only becomes relevant after you've lost your original deposit. A consolation prize would be a more accurate term.

Remember, these calculations only give you averages. The RTP (return to player) of a casino game is based on the results of thousands of rounds. Your results within a single gaming session will vary.

Conclusion: Are bonuses worth taking?

Depends on the bonus.

A good bonus can make your games last longer and act as a second chance if your real money runs out.

However, a bad bonus may actually hurt your chances of coming out ahead.

Here are our casino bonus tips. Only accept a bonus if it's:

Unfortunately, this stuff is usually in the fine print. Most players pay more attention to bonus sums, bonus percentages, and free spins. Although they make the bonus more appealing, they're just the icing on the cake.

Don't be a sucker. Choose your bonus carefully and have fun playing.

Casino bonuses and responsible gambling

As good as some bonus offers seem to be, it's worth reminding yourself exactly why casinos have them. Bonuses have two main goals:

Also, you should be realistic about what's the probability of winning and, more importantly, withdrawing your winnings.

If you've accepted an offer for a deposit bonus, you still have the playthrough requirements to think about even if you happen to win. The bigger the bonus and larger the wagering requirement, the slimmer the chances are for you to actually get the money out.

Only play with the funds you can afford to, and never gamble away the money you need for necessities or if it means cutting back from something else. Use the tools for responsible gambling the casinos provide and set limits for your deposits and/or losses.

Casino bonus FAQ

You want to convert your casino bonus balance into withdrawable cash. This happens by meeting the wagering requirements. Here's how wagering requirements work:

  • The wagering requirement may apply to the bonus sum (B), your original deposit (D), or both (D+B).
  • Bonus sum x wagering requirement multiplier = total amount to wager.
  • Wagering starts when your deposit amount runs out.
  • Only bets made with bonus money count as wagering.
  • Completing the wagering turns your remaining bonus balance into withdrawable cash.
  • Wagering requirements over 35x (B) can be hard to meet.

Many US online casinos use bonus codes to unlock casino bonuses to players. The rewards earned vary from one site to another, but the best online casino bonus codes unlock:

Not all sites require you to enter a casino promotional code to get your bonus. When a casino reviewed on Bojoko features a first deposit or no deposit bonus code, this info is displayed on the listing page. In addition, you can see the bonus codes on our curated casino lists.

  • An online casino bonus code is a case-sensitive combination of letters and numbers.
  • Use the casino bonus code to redeem a special offer when prompted on the casino website.
  • You'll normally be requested to input the code when you create an account or make your first deposit.
  • In some casinos, you may need to contact customer support to redeem your code, although this has now become rare.

On Bojoko, you can find the bonus code in the casino reviews.

Many casinos want to save their most generous bonus offers to trusted partners like Bojoko. With a special bonus code or a unique link, you'll get exclusive casino bonus offers that can't be found anywhere else.

Take a look at our bonus list, apply the use the quick filters to sort out the results, and bag some secret goodies.

Many casinos feature deposit bonuses that sound appealing. To make sure the bonus is right for you, check out the following details:

  • Maximum bonus sum
  • Bonus percentage
  • Minimum qualifying deposit
  • Wagering requirements

Use our bonus selection tool to filter and sort casinos based on these factors. In our casino reviews, you'll also see the Significant terms and conditions. Read them carefully to avoid nasty surprises, such as bonus caps.

Casinos exclude some banking methods from bonuses. Casinos usually ask you to make your first top-up with one of the following:

  • Credit or debit card (Visa & Mastercard)
  • Wire transfer
  • PayPal

Credit and debit cards and wire transfers are practically always available and PayPal is also quite common. Here we have gathered All casinos accepting PayPal.

You can read more about the Excluded banking methods in the T&C section.

Gambling laws vary depending on where in the world you are playing. Some places have taken a more protective stance on casino gambling and bonuses than others. And this is where forfeitable bonuses come in.

A forfeitable bonus is held completely separate from your real money and it can be forfeited at any point. This means that you can withdraw your real money and winnings made with it at any point without having to worry about wagering.

In the UK, all casino bonuses have to be forfeitable, but in the US, it is a perk that some casinos may offer.

Related: How to measure the value of a deposit bonus.

A sticky bonus is the exact opposite of a forfeitable bonus. In a sticky bonus, the wagering requirement is usually low and the bonus percentage high. So far so good. However, the initial bonus sum is deducted from your balance when you withdraw your winnings. The sticky bonus itself can never be withdrawn.

A sticky bonus isn't usually a good deal for the player. In recent years, sticky bonuses have started to disappear from casinos.

From the casinos' point of view, some banking methods are more beneficial than others. Understandably, casinos try to channel the players to use these methods.

The most common way is to remove handling fees. However, casinos also offer additional bonuses for people using the preferred banking methods. The bonus percentages aren't big, but they're sometimes added on top of your standard deposit bonus.

Banking method bonuses aren't as common as they were a couple of years ago. Also, the set of payment methods available in online casinos has become more similar.
