1-minute introduction: What is a casino bonus?
A casino bonus is something the casinos can attract new players with, or offer to existing players to keep them interested. As a new player, the most relevant bonuses for you are included in the casino's welcome package. When you sign up to a casino, you can often get:
A no deposit bonus: a small amount of bonus money or free spins to popular slots
A deposit match bonus: the casino matches your real money deposit in bonus funds
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.
US casino bonuses explained

Different types of casino bonuses
First, you need to understand the difference between deposit and no deposit casino bonuses:
No deposit bonus lets you try the casino without making a deposit and risking any of your own money.
Deposit bonus gives you bonus money and/or free spins, but you need to make a deposit to claim it.
These are the main types of bonuses available in US-licensed online casinos:
Bonus funds - casino money that needs to be used in the games
Cash - money that has no strings attached and can be withdrawn
Free spins - free rounds in pre-selected slots
In addition, you need to consider these things while choosing a bonus:
Minimum deposit
Maximum bonus sum
Wagering requirements
Other terms and conditions
Below, we'll look at these factors in more detail.
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.
Pros
No need to risk your own money
You only need to create an account
Chance to win real money
Cons
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.
Verdict
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.
Deposit bonuses 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.
Pros
High bonus value
Low playthrough requirements
Often multiple bonuses available
You've already confirmed a banking method, so withdrawal is easy
Cons
The minimum deposit qualifying for a bonus may be high
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.
Verdict
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.
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.
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.
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.
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.
Optimizer
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 to 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.
How to find the top online casino bonuses
1. Find a casino with the bonus you like
You can find a great variety of US-licensed online casinos here on Bojoko. Check the casino list and find a bonus that suits you the best.
2. Read the expert reviews
Read what our experts have said about the casino. Their reviews can help you see if the casino is right for you.
3. Go to the casino
Every review page has a big ‘PLAY HERE' button. This takes you straight to the casino. And if there is a special bonus available, this button activates it.
4. Register an account and claim your bonus
Once you get to the casino, register an account, make a deposit and claim your bonus. Use a bonus code when depositing if required.
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 with 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 the 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:
Wagering requirements - The amount of money you need to bet before the bonus funds can be withdrawn
Minimum deposit - The smallest deposit sum that qualifies for a bonus
Time limits - The time you have to claim the bonus and complete the wagering
Max. bet - The largest bet per round allowed when wagering your bonus
Restricted games - Not every game helps you complete the wagering
Winning caps - If you win big, the casino confiscates the part going over the maximum win.
Excluded banking methods - Deposits made with certain payment methods don't qualify for the bonus.
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 amongst 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:
Get the biggest bonus with the smallest deposit
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:
Bonus sum - If you make a big deposit, the casino may not match the whole sum in bonus funds
Wagering requirements - Check if they apply only to the bonus or also to the deposit sum
RTP - The highest paying game that contributes 100% towards completing the wagering
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:
Bonus sum = Your deposit x the bonus percentage
Total sum to be wagered = Your bonus sum x wagering requirements
Expected loss = Total sum to be wagered x (1 - RTP)
Expected value = Expected reward - expected loss
"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%:
Bonus sum = 100% x $100 = $100
Total sum to be wagered = $100 x 30 = $3,000
Expected loss = $3,000 x (1 - 0.97) = $90
Expected value = $100 - $90 = $10
"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:
Forfeitable: you can cancel the bonus if you win while playing with real money
Low wagering: you have something left to withdraw after the playthrough is done
Uncapped: there's no upper limit to your bonus winnings
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:
Lure new players in by promising more money to play with
Keep existing customers coming back
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.
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.
