Online Casino Bonus

Every unique online casino bonus is a promotional tool used to convince a player to try a website. A variety of bonuses exist, including the signup bonus, Freeplay bonus, and reloads. We recommend legitimate and trusted online casinos that offer the best bonus for your money. Learn about each type of bonus that online casinos offer, as well as what players need to know about each one.

An online casino bonus is similar to the plastic Freeplay slots cards handed out to customers by promotional staff at brick-and-mortar casinos these days. The idea is to get players to try out certain games and get used to playing at a casino. For that reason, the money spent is worth the investment in advertising.

The Internet has thousands of websites competing for customers. That means they’ll offer house money in the form of bonuses to get you through the front door and into the online casino. This article discusses any restrictions and obligations you might face. It also provides inside information on accessing your free cash, while discussing common problems you might face.

What Are Casino Bonus Codes?

A casino bonus code usually looks like an online password, containing letters and numbers. Each online casino can have several different bonus codes, depending on the type of promotions it offers. We are able to provide our visitors with the best bonus codes at some of the most reputable online casinos.

Using a bonus code is very easy. Once a player logs into their casino account and goes to their personal dashboard, they’ll find a menu for making deposits, accepting bonuses, and redeeming bonus code information. Below you will find a step by step process on how to redeem any of the online casino bonus codes we provide on this page.

How to Use a Casino Bonus Code

Players who’ve never used a casino bonus code should use the steps below as a guide. The process is quick and easy. The main challenge is finding the best casino bonus code information for your situation. Use your personal dashboard or player menu to find the promo codes on the official site.

Go to your Player Dashboard. Choose the option for “Bonuses” or “Manage Bonuses”.
You’ll see pertinent information like bonus funds, active bonuses, available bonuses, and redeem bonus code. Choose “Available Bonuses” to see what offers you have.
Once you see the offers, pick the code for the bonus you want to accept. In the box that says “Redeem Bonus Codes”, input the exact code information. Assume that the code is case-sensitive.
If you don’t see a code or the casino isn’t offering a code you want, contact the site’s cashier and ask if other promotions are available. Sometimes, customer support provides additional bonus code choices to those who say they would like to play, but don’t find an offer they like.

How to Use a Deposit Bonus Code

A deposit bonus code is a specific type of promotion. It is available when you make a deposit to your account. These codes are offered either as a first deposit bonus or as a reload bonus. In either case, the player receives an incentive to fund their account.

How to Use a Free Play Bonus Code

Free play bonus codes are also available. Two types of free play codes exist. One type is available when you register. This type, a no-deposit bonus code, allows you to play with real money without making a deposit. The second activates when you make a deposit. The casino’s cashier adds the free play money to your account on top of any other bonuses you’re received. In either case, you’ll redeem free play promo codes on the same sub-page in your player dashboard as the codes described above.

How to Use a Reload Bonus

To receive a reload bonus, search the promotions page for the full list of promotional offers.
Find the reload bonus you like, searching for words like “daily”, “weekly”, or “monthly” to locate the offers you want and find any promo codes associated with it.
Once you find the promotion you like, use the casino dashboard to make a deposit similar to the one offers.
Many reload bonuses require a coupon code, so search the promotions page for code information and redeem the promo code through the input box on your dashboard page.
If you have any questions about a reload bonus code, contact the cashier department of the website. Customer supports sometimes emails coupon codes to your email address.

Online Casino Bonus Types

Before players consider claiming a bonus offer, they need to know which are the online casino bonus types that are offered. Below is a quick scorecard of what you can expect.

  • Deposit Bonus

    Offered to players who make a deposit into their casino account. This is the best online casino bonus, as they offer the most money to players.

  • Freeplay Bonus

    Offered to players who register an account at an online casino. They do not have to fund that account in order to claim the bonus. These are usually much smaller than the deposit bonus.

  • Reload Bonus

    These are for loyal and recurring players who have cleared their deposit bonus requirements already. These are a reward for loyalty after each time a player makes a deposit.

  • No Deposit Bonus

    Players that join an online casino are often given a no deposit bonus so that they can start playing right away, without having to make a deposit first. These are great ways to win extra cash before making the first deposit.

  • Games-Specific Bonus

    Terms and condition which restrict play to the games with the worst odds. It also describes a special one-time bonus offered to promote a new game.

Casino Deposit Bonus

Online Casino deposit bonusWhen players make their first deposit at an online casino, it triggers the deposit bonus. With that initial deposit and sometimes up to the first 3 payments, the online casino will add a free cash bonus to your account; they match the amount you pay. These are often referred to as a Sign-Up bonus. To find the best online casino sign up bonus, see what the match rate is and compare it to the others, using the steps below as a guide.

The match rate on a deposit bonus is very important. If the online casino bonus matches $1 to $1, that is called a 100% bonus. If a casino matches $1 to $2, that’s a 200% bonus. If you have to contribute $2 to get $1 in bonus cash, that’s a 50% bonus. One-hundred percent is fairly standard, so those which offer two-hundred percent are making a nice offer. The 50% bonus is usually for additional deposits.

Online casinos that offer multiple deposit bonuses often front-load the first payment. That is, you might receive a $500, 100% bonus offer. If you deposit $500, your account will show $1,000. If you receive cash on the second deposit, this might be $500 at 50%, meaning you would need to deposit a full $1,000 to receive $500 in bonus cash. The first deposit is usually the highest.

First Deposit Bonus

The first deposit bonus a casino offers is important to attract players. This is your first interaction with a casino. If you are test-driving a number of different brands, then the wagering requirement is vital. Although, not every welcome bonus is a first deposit bonus. Be sure to check out the details before making your first deposit.

Maxing out the Bonus

Many gamblers plan their payments to max out the deposit bonus offer. It makes sense to do so if it’s affordable. In the scenario above, a gambler who intended to fund their account with $1,000 of their own cash might only deposit $500 in the first payment. They would be able to get more bonus cash by making two deposits, instead of only one. Read the terms and conditions closely in order to know how to get the most out of the online casino bonus.

Best Deposit Bonus

Finding the best deposit bonus can be useful for players wanting to max-out their bankroll. has the best deposit bonus for US players, giving them up to $5,000 extra over their first 5 deposits. Lucky Red Casino has the best deposit bonus for international players, giving them $4000 at a 400% rate, which means you receive $4000 when you deposit $1000. Casino

No Deposit Bonus

No Deposit BonusIn the last 5 to 10 years, online casinos began to offer a no deposit bonus. A player needs an account for one of these, but this offer does not require they fund that account. For that reason, it’s also called a “Freeplay bonus”.

With the freeplay option, players are allowed to use house money to make some bets and try the casino games without risking their own cash. It’s a way to play with casino’s own money, with no risk of losing personal cash, with the added perk of having no obligations.

In a survey of over 50 online casinos, the bonus ranges between $15 and $900, but that does not mean the bigger offer is the better one. You’ll need to read the wagering requirements, sometimes known as the rollover requirements, to know what the conditions are of a $900 Freeplay bonus. If it sounds too good to be true, it usually is.

Mobile Casino No Deposit Bonus

Mobile casinos offer the no deposit bonus as well. In my experience, the minimum bonus tends to be for smaller amounts of free cash. In one or two cases, the max Freeplay bonus is even bigger. In a survey of 25 mobile casinos, I found them in the range of $5 to $1,250 (for Roxy Palace).

Online Casino Free Bonus

Free casino bonusThe deposit free bonus is one of the most popular and used at online casinos. These are called either “no deposit bonus” or “instant play bonus”. In either case, a player receives a small amount of promotional cash to enjoy real money gambling at the casino. This house money is meant to encourage players to test out the games and software. They hope players enjoy the experience and make a deposit.

Online casino deposit free bonus offers tend to be small, ranging from $5 to $50. Some sites have been known to offer much bigger payouts for sign-ups. The important thing is you don’t have to make a deposit before receiving this free cash bonus. These free bonus offers come with different wagering requirements. These can be as low as 1x the bonus, but it usually involves 20x to 50x the bonus received.

For example, a $10 free bonus has a rollover of 25x the bonus amount. To withdraw this money, you would have to wager $250. The wagering requirement (or rollover) protects the casino from giving away too much cash, while it gives lucky players the chance to win real money without making a deposit.

Best No Deposit Bonus

The best no-deposit bonus lets a player bet with house money before risking their own cash. Casino gives no-deposit bonuses to players who register for a new account, offering a free bonus chip or small payment to your casino account as soon as you sign up. Cafe Casino has the best no-deposit bonus for US players: a $10 free chip with a max cashout of $125. Sloto Cash has the best international no-deposit bonus. SlotoCash gives a $100 fee chip to new signups, but players need to redeem the bonus code PERFECT100GIFT to receive this offer.

Reload Bonus

casino reload bonusAt a time, online casinos did not offer a free cash bonus for reloads. It’s becoming more common these days, and it was long overdue. A reload bonus is an ongoing offer for loyal customers who continuously make deposits into their account. The idea is that the returning players’ cash is just as valuable as the new players. Also, these members have shown loyalty and should be rewarded. Many of the same terms and conditions that apply to these bonuses are not always as large as a new customer’s bonus.

It should be mentioned the reloads are in addition to the VIP rewards program. Online casinos, as well as mobile casinos, have a rewards program for ongoing customers. This is like the slots club at a land-based casino. The more you play, the more money perks you receive. For those unfamiliar with casino club cards, it’s like the rewards program on your credit card. The reload bonus is an enhancement to these other rewards, which is one reason it’s often not as substantial as the initial casino deposit bonus.

Best Reload Bonus

A reload bonus given to continuing players for their loyalty. Several different types of reload bonus exist, including a weekly bonus, a monthly bonus, and a standalone reload bonus. BetOnline Casino has the best reload bonus of $1000 USA players who use the bonus code CASINO25. 32red Casino has a $150 reload bonus for international players.

Game-Specific Bonus

casino game bonusesYou probably know already that slot machines have higher house edge than blackjack and video poker, and usually a higher house edge than craps and baccarat. When making an offer, a slots player would be getting a worse deal if they were offered the same size bonus as a blackjack player. For that reason, the online casino bonus for specific games are often offered to players.

These take two forms

One, a player might be restricted to a handful of games they can play, or even slots-only requirements. For instance, you might learn you have to play the slots with your deposit bonus or Freeplay offer. If so, playing blackjack does not meet the requirement. For online casino slots, this is also commonly known as a Free Spins Bonus; as explained below.
Two, a player might be able to play any game they want, but the play-through requirement might be different for two different games. It’s not uncommon to see slot machines fulfill the wagering requirement at 100% while blackjack fulfills the requirement at a 10% rate. In this case, you would have to wager 10 times more money on blackjack than you would on slot machines.

Free Spins Bonus

Instead of offering an online casino bonus, the player is offered free spins on video slot machines. The first site to do this was Royal Vegas Casino, which offered 1600 free spins instead of a welcome bonus.

It is easier for a player when an online casino offers a free spins bonus. Here are some of the advantages of this bonus:

Thumbs Up
Advantages of Free Spins
  • Players don’t have to worry about wagering requirements and contribution rates.
  • They don’t have to be concerned with whether they can cash out the bonus money and winnings, or only the winnings.
  • The gambler knows whatever money they have at the end of the free spins is theirs.

As time passes, expect the free spins bonus will become an industry standard, at least for legitimate online casinos. Be sure to look for the free spins bonus at any of the best online casinos.

Best Games Bonus

A games-specific bonus targets one game or specific types of games. Categories might be slot machines, video poker, table games, or even a specific table game (like blackjack). Las Vegas USA Casino has the best games bonus for US residents. Their promotion is a $3000 table games-specific bonus table games and video poker, but you need to use the bonus codes 150BONUS and IDBLASVEGAS. No maximum winnings apply, but some table games are restricted.

What to Look for in a Bonus

Those are the broad online casino bonus types that players can receive. Deciding which are best is not a matter of finding the biggest payouts, though. Several factors need to be considered.

  • Bonus Size
  • Match Rate
  • Wagering Requirement
  • Games Selection
  • Window of Time
  • Free Spins Offered
  • How Withdrawals Work

Read a casino’s terms and conditions, because other requirements are likely to be in effect. The devil is in the details, so a seemingly great offer might not be worth much. Avoid sites which are not up front with their bonus offers, because they likely do the same in other areas.

Size of Bonus

Size of the Bonuses

The size of a casino bonus is the hook that catches your attention. Getting the biggest bonus you can use is important. The words “you can use” are important, though.

If the wagering requirement is unrealistic, the size of the bonus doesn’t matter. If you can’t afford to max out a big bonus, then the size also doesn’t matter. In that case, the matching rate is more important.

Match Rate

Match Rate

This is the rate at which your dollar amount is matched. Deposit bonus matches dollar-for-dollar. In most cases, that means $1 you deposit is matched with $1 the casino adds to your account, like an employer matches deposits in a 401K plan.

The higher the matching rate, the better. This is given as a percentage. 100% is standard, indicating that each dollar you spend gets you a dollar in return. Higher percentages are better for all types of players. This would include low rollers, mid-stake players, and even high rollers. Everyone wants to take advantage of a free online casino bonus.

Wagering Requirement

Wagering Requirement

Players who receive any of the online casino bonuses needs to understand the wagering requirements at casinos. The operator is going to want to protect itself from players who shop for bonuses. A casino also can’t stay in business if it gives out tons of free money that is easy to withdraw. The wagering requirement protects the operator.

To withdraw casino bonus money (or winnings), a player must meet a wagering requirement, also called a “play-through requirement” or a “rollover”. The rollover requires a person to wager the amount of their bonus a certain number of times before cashing out. That number usually ranges between 20x and 50x. If you receive $10 as an online casino bonus and have a 30x requirement, you would have to wager the equivalent of $300 before you could withdraw the free cash given through the bonus.

Game restrictions

Game Restrictions and Limitations

One major stipulation is the games you might be required to play. Some online casinos restrict which games you can play when offering a free cash bonus. Slot machines are usually allowed. I described this above, but I want to remind players to keep this in mind when comparing casino bonuses.

Keep a special eye on table game restrictions. Table games are not allowed most of the time. Blackjack is the game most often disallowed or restricted because it has a low house edge.

Window of Time

Window of Time

After a certain amount of time, an online casino bonus could time-out. There are bonus offers which are limited to 24-hour, 48-hour, or 72-hour windows. Also, a weekend bonus which ends at 12 midnight on Monday.

Most online casinos have a 30-day or 60-day window for each bonus, but remember to satisfy these conditions, or else players could lose their chance for extra cash.

Free Spins Bonus

Free Spins Bonus

Some online casinos dispense with the use of money bonuses and offer a free spins bonus for their slot machines. While a majority of casinos do not offer free spins, there are some that do. A quick scan of the bonus offers in the database showed 6 online casinos that offered free spins as first deposit bonuses. 17 mobile casinos offered free spins no deposit bonuses.

These offer a wide range of spins: between 7 and 1500. When the free spins are over, you pocket whatever cash you’ve won. Although, you have to be over $0 for the total session to withdraw the winnings. In this case, getting 1500 spins is actually a disadvantage, because the house edge means it’s more likely that the total money from your total spins will be below zero.

Cash out winnings

Cashing Out: The Casino Bonus or the Winnings?

Players need to know other stipulations when it comes to cashing out an online casino bonus. Some casinos only allow people to withdraw their winnings. That is, they don’t receive the bonus money they were given, but they get the winnings from having won while wagering with the bonus. Others allow people to withdraw the bonus and their winnings. In either case, the player is not obligated to continue once the bonus rollover requirement has been met.

Read closely to see which of the two offers you’re receiving. If the online casino bonus you’re offered is $20, it might not matter to you. Comparatively, if you’re offered a $900 bonus, the difference between the two is significant.

Finding the Best Casino Bonus

Readers might have guessed by now that finding the best online casino bonus is not easy. To find the best casino bonus, you have to read more than the sales copy that the sites advertise. You’ll need to get down into the casino’s “Terms & Conditions” page for the wagering requirements. You might need to read through the FAQ for clarification, or even communicate with customer support on live chat. Get the information correct before making a decision.

It helps to have a trusted review site or two to get reliable, accessible information.
