What is a Bonus Code?

New Casino Bonus Codes

A bonus code is a string of alphanumeric characters that online casinos use to promote time-sensitive offers or new game releases. They’re used to encourage casino players to try out their platform and reward existing ones by granting them access to promotional offers. That's why you’ll see online casino promotion codes tied to specific offers like a welcome match deposit bonus, free spins, or a reload business. 

You can search for casino promo codes online, but that can be time-consuming. That’s why we recommend you use our updated list here at TopCasinos for quick access to the best bonus codes for online casinos. We’ve done all the hard work for you, allowing you to see bonus codes for the best offers at a glance.

Not every casino bonus code is for every player, however. Yes, some bonus codes are promoted on a casino’s homepage or promotions page for all players to claim, but others are more exclusive. A special online casino casino bonus code, for example, can be promoted to a casino’s VIP club members only.

Then there are tailored bonus codes that are sent to your phone or email address when your birthday rolls around. These types of bonus codes will be personalised to work for you only. Whether it's new casino sites or existing ones, the latest no deposit bonus codes are a big part of online casinos culture.

Why Use a Bonus Code? 

There are some great reasons to use a bonus code, which we’ll look at below. Every online casino is unique, so it’s no surprise that they offer bonus codes to some pretty special promotions. They also use them to stay relevant in a very competitive industry where it’s more difficult to stand out. But there are several key advantages for you as the player, so don't hold back on claiming your piece of the pie.

  • Reduced rollover requirements: cash out your bonus early with fewer wagering requirements.
  • Some bonus codes increase the max winnings: increase the value of potential winnings.
  • Bonus codes let you try new games for free: try out new games at the casino.
  • Refer a friend: get rewarded for recommending friends to your favourite casino.

Reduced Rollover Requirements

Other than providing enhanced rewards, some casino bonus codes reduce the wagering requirements. If you’re a new player, you might not think that this is especially important, but the seasoned gamblers among you will know differently. So bear in mind that you'll need to wager the bonus amount a set number of times before you can cash out your bonus winnings.

The good news is that some free bonus codes reduce the number of times you’re required to play through the bonus, giving you more time to meet the condition. These bonuses, however, are often issued after you make a deposit. So if you want to give them a go, you’ll need to contact customer support after funding your account.

Some Bonus Codes Increase the Max Winnings

One condition often included with bonus codes is when the corresponding bonus limits the amount of money you can win with a specific reward. While the bonus code can’t change the limitation, it can increase the value. That means you have the potential to win more, which is never a bad thing.

Bonus Codes Let You Try New Games for Free

Bonus codes grant you access to more games for you to try out. There are so many online casino games out there that choosing just a handful to try can be a challenge. That’s why there are bonus codes that allow you to try out new games. So if you don’t feel like spending your own money on a new game, there may just be a bonus code that will let you try it without it costing you a penny. Some of these bonuses can be pretty huge if the casino wants to promote the game badly enough.

Refer a Friend 

You can also use a casino promo code to pass on to a friend via a special link. This unique URL tells the casino that you’re the one who sent the code. If that player signs up to the site, the casino will reward you with a bonus. So the more friends you invite, the more potential rewards you’ll have coming your way. Hey, it pays to have friends, right?

The Different Types of Bonus Codes 

There are a number of different types of bonus codes available at online casinos. There are so many options, in fact, that you just might feel overwhelmed. Here’s a quick rundown to help you get your head around all the great offers you can find bonus codes for online.

  • No deposit bonus codes: Try out a new casino without using your own funds.
  • Bonus codes for free spins: Free site credits to use on your favourite slots.
  • Bonus codes for mobile casinos: Enjoy a bonus on the go on your smartphone or tablet.
  • Bonus codes for live casinos: Play with bonus money at a simulated land-based casino.

No Deposit Bonus Codes

No deposit bonus codes are codes that provide you with a taste of an online casino without you having to deposit any funds. You can expect free spins and free cash with these codes. So it probably won’t surprise you to learn that you won't find too many no deposit bonus codes online. However, you’ll find some no deposit bonus codes 2024 at TopCasinos that give you the perfect introduction to online casino games. So if you're looking for the best no deposit casino bonus codes, look no further than this page. We have no deposit casino bonus codes for existing players, as well as new casino players.

Bonus Codes for Free Spins

Bonus codes for free spins are codes you enter to give you free site credits at an online casino. These site credits allow you to try out the slots as well as learning more about the casino itself without it costing you. These are typically offered as a welcome bonus to tempt you to give these slots a try.

Bonus codes for free spins are sometimes offered as a part of a combination offer with a deposit match bonus. The amount of spins, however, isn’t dependent on how much you deposit. You just need to make sure you deposit the minimum amount required to qualify for the bonus.

Bonus Codes for Mobile Casinos

Bonus codes for mobile casinos are codes you can enter on your mobile device to take advantage of a bonus on the go. Mobile gaming is becoming increasingly popular, with most players now using their smartphone and tablets to enjoy their online gambling activity. So it’s not a shock that players are seeking mobile bonus codes online.

Bonus Codes for Live Casinos

Bonus codes for live casinos are those that allow you to enjoy a real-world casino experience in the comfort of your own home. While free casino bonus codes are less common for live casino play, they do exist.

And it only makes sense to expect more, seeing as there are more live casino games being introduced every year. After all, live casinos will want to attract new players to give these games a try. So if live games are your thing, it’s worth regularly checking at TopCasinos to see if there are any new bonus codes being promoted.

  • Bet size limit – determine the max wager you wish to play per spin when using your bonus.
  • Eligible games – you can’t use your bonus on all of the casino's games. So you need to know which games you should avoid playing in order to make the most out of the bonus. The list of excluded games are found in the casino’s terms.

Frequently Asked Questions

Do I need to make a deposit to use a bonus code?

Making a deposit to use your bonus code isn’t necessarily required. Although, it depends on what type of bonus the code is for. You can find both deposit bonus codes and no deposit casino bonus codes, meaning it’s possible to try out your favourite games for free simply by entering only the bonus code and a few additional details.

Does every promotion need a bonus code?

No, not all promotions require a bonus code. If they don’t mention or provide you with one, you’re free to just sign up and claim whatever welcome bonus is on offer. And that goes for any other qualifying promotion. You should always check the promotions page and bonus terms, however, in case a code is mentioned there.

How do I enter my bonus code?

Enter the bonus code (either type it or copy and paste it from our site) when providing the casino with your details. If it’s for a deposit bonus, it will usually add money to your account. If you find online casino no deposit bonus codes, there will most likely be free spins rewarded to you. Once you’re all signed up and logged in, you can get started taking advantage of the bonus right away.
