Types of Bonus Codes

Casino bonus offers come in all sorts of shapes and sizes, and sometimes different codes may give you completely different benefits.

One may give you a couple of free casino bonus spins without a deposit, another - a bigger match on your first deposit than the welcome bonus typically awards when making a casino account. These are some of the most common bonus codes:

The most common type of bonus code - essentially boils down to "input this code during deposit and gain this deposit bonus on the house". Sometimes the deposit casino bonus will be better than what you'd get otherwise, while other times it'll add something extra, like bonus spins for a slot that you like. More often than not, this deposit bonus code is activated during your first deposit, but sometimes the casino may release an offer for returning players as part of a loyalty program which also requires a bonus code. This leads us to...

While closely related to the deposit bonus code, the promo code is ultimately its own thing which, unlike that code, is usually not part of the welcome package. Rather it's a free bonus which is aimed at returning and existing players. Maybe the online casino bonus offers players who deposit free spins for a specific slot game, or a deposit match that only works on certain days of the week. Sometimes these promotional conditions will activate automatically, but other times the deposit casino bonus can only be triggered with a bonus code.

Free spins bonuses are fairly common in the world of online casino, but sometimes you need to use a code to take advantage of those delicious bonus spins! The way this type of code works is different, as sometimes you'll gain a couple more free spins alongside your deposit bonus, while other times the offer is exclusively for bonus spins. The former version is more common, but the latter is often found in casino no deposit promos.

On the surface, this is no different from any of the other codes we've discussed - it can still give you a deposit casino bonus just like any of them. The catch? You won't find that code listed on the casino page. Instead, that code may be exclusive to their social media feed, or perhaps they can send it over to a review site as thanks for a good review which brought them a lot of players.

That's why it's always important to check the review page for the casino you're interested in right here on casino.online - sometimes we'll have a code for great offers, like no-deposit free spins, you won't find anywhere else.

How to Deposit with a Casino Bonus Code

Making a deposit using a bonus code is actually not too different from making any other online casino deposit. Realistically, the biggest difference is that you need to input a specific code in order to take advantage of your bonus spins, deposit casino bonus, or whatever the terms of the promotion are. But what if this is your first deposit and you're not sure how to make it?

No need to worry: We've outlined a step-by-step guide for you! Here's how to make a casino deposit using a bonus code:

Sign up with the casino

Input your details and create your account, then confirm it.

Check the bonus conditions

Make sure that you qualify for the bonus, the offer is still active, and you can meet the wagering requirements.

Make your first deposit

Click on the Deposit button and choose how much you wish to deposit.

Enter the bonus code

Before you complete your deposit, enter the code in the proper field.

Confirm that you got the bonus

Check your account and make sure that you got the bonus.

What to Look Out for in a Bonus Code

As we said, using a code will almost always give you a better casino bonus than not using one. But just in case you're not sure, here's a handy-dandy checklist that will help you find the best casino bonus codes for you:

Should You Use a Promo Code at All?

99% of the time, the answer is absolutely "yes"! The deposit bonus or free spins you'll get from a code will almost always be better than what you'd get without it. After all, if you could get a better bonus without the code, then what's the point of having it there in the first place, right?

Many deposit bonus offerings can only ever be claimed by a bonus code, as online mobile casinos you can access on Android want to know that you're actively interested in the bonus instead of just claiming it because it's there. A lot of the time even when you can claim a bonus with or without a code, using the code will give you a better deal (like extra free spins or lower wagering requirements). So unless a code will actually give you a worse match bonus (which almost never happens), go ahead and use that code!

Sadly, as fun as the idea sounds, codes aren't really as simple as punching in some letters and numbers and getting free money - if that was the case, then anyone would just use the code and then immediately withdraw the money without playing any games!

What to Do if a Bonus Code Doesn’t Work

Don't panic! There are many reasons why a code may not work, and not all of them mean that the code is irreparably broken. First and foremost, verify that the code has been typed in correctly. It's best to copy/paste it rather than type it, even if it looks very simple. If that still doesn't work, verify that you're activating it correctly. Some casinos may need you to press a button to apply the code before you proceed with your registration, so make sure you've done that!

If the code still refuses to work, it might have expired. Deposit casino bonuses usually change all the time, and free spin offers may alter the game they're attached to. Try to Google the code and see whether the bonus it was attached to doesn't have a time limit.

Another option may be that a particular offer (for example, free spins for a particular slot) may be exclusive to a different country from yours. If you've double-checked and are still absolutely certain that the code should work, try writing to support and asking them directly. They'll give you a straight answer, and might even directly activate the bonus without the code if it's a technical issue!

Mobile Casino Bonus Codes

Mobile casino deposit bonuses have become rarer now that the mobile market has a much bigger share, but they still exist. The idea is that an online casino may offer players a deposit bonus exclusive to the casino's mobile app to encourage players to download it. Today, most players actually prefer to play casino games on mobile rather than on desktop, making mobile-exclusive deposit bonuses obsolete - but it's worth checking anyway.

To verify whether the casino has any mobile deposit bonus codes, simply download the mobile app and check the promotions (or bonus) page. There may be a deposit bonus labeled as "mobile" - if there isn't, just compare the casino bonuses on mobile and desktop and check if there's anything extra. Sometimes redeeming the bonus may be as simple as merely finding a code on mobile and inputting it on desktop!
