What are casino bonus codes?

Casino bonus codes are promo codes you use in an online casino to unlock bonuses. Casino bonus codes are there to brighten your gaming experience. Just like the promo codes you’re used to when shopping online, bonus codes give you a phenomenal discount or more value for your investment.

Bojoko makes this dead easy to verify with our casino lists and reviews. You can quickly check if a particular casino offers bonus codes and what the bonus code is with our sorting tool above.

How do bonus codes work?

When you create a new player account and make your first deposit in an online casino, you'll usually be invited to enter a promotional code. Each bonus codes casino is different in the way it handles this process. 

EXAMPLE: A typical bonus code offer looks like this: “Get 100 extra spins when using the code 100SPINS on your first deposit.”

When a casino listed on Bojoko features a bonus code, the components and value of the bonus can be picked up from the casino review.

Where to find bonus codes for casinos

There are different routes to acquiring bonus codes. Here's how you can get the bonus codes you're after.

When you sign up with a new casino, you'll be notified about the latest deals and campaigns, so remember to take note of any bonus codes you might wish to use later. A bonus code can quickly transform an average bonus package into a pretty sweet deal.

Comparing bonus codes casinos

Bonuses rarely come with no strings attached, and those earned with casino promo codes are no exception. Always carefully weigh the extra value gained against the wagering requirements and other terms and conditions.

You’ll find the fine print for each casino and its bonuses in the reviews on Bojoko. When you're familiar with the contents, start working your way to the best bonus codes casinos.

Get the bonus code for the first deposit.

Bonus codes for players depositing money in a casino for the first time are the most common and easiest to get. These casino bonus codes can only be used if you're a first-time depositor, so don't forget to apply the code the first time you're transferring funds into your player account. Even if you don't intend on beginning your experience with a bonus, you can save the bonus code for easy access once you're ready to make a choice.

Measure up the welcome bonus against others.

Comparing welcome bonuses from a vast range of different casinos can be done in seconds on Bojoko. Bonus codes are often the key that unlocks welcome bonuses, so you can compare and contrast all the deals available with our sorting tool. As an added bonus, Bojoko enables you to compare just the casinos that have the qualities you like. Whether that's a preferred banking method or a low wagering requirement, single out the casino with the right bonus code to match.

Select the best first deposit bonus.

Naturally, you'll want to choose the best first deposit bonus from the bonus codes casinos. The bonus code itself doesn't tell you much about the offer, so you'll have to investigate the deal yourself.

Evaluate the total new player bonus.

Consider every aspect of the welcome package: the first deposit bonus, no deposit bonus and other freebies. If you analyse all the important stuff, you're bound to arrive at the best bonus code. 

See how many extra spins are included.

If the casino's throwing in a number of extra spins with the bonus code, opt for the one with the highest number. No deposit bonuses are also commonly redeemable via bonus codes. 

Mind the wagering requirements.

Of course, wagering requirements directly affect the quality of bonus codes. Go for fair wagering requirements at or below 35x for a good chance to clear them painlessly.

New player bonus codes vs campaign codes

There are different types of casino bonus codes for different types of players. You can decide which ones to go for based on your needs and preferences as a player.

Online casinos don’t normally allow players to activate multiple bonuses at the same time. That’s why we recommend you first take advantage of the new player bonus code offers before diving into to the world of campaign offers.

Do you always need bonus codes for casinos?

As a new player, you can get some very competitive bonuses using casino promo codes. You'll find other casinos that don’t use them at all and still manage to offer similar deals, so don’t limit yourself to just bonus codes if you’re on the hunt for a great deal. 

If you find an awesome casino but the bonus terms don’t take your fancy, you can always refuse the bonus and play with your own money right off the bat. This way you don’t have to worry about wagering requirements and other bonus conditions – everything you win, you keep.

The key lessons to take home from using bonus codes can be distilled into three simple rules:

  1. If the casino offers bonus codes, you get better deals using them.
  2. The public promo codes found on casino sites themselves offer similar bonuses to casinos without any bonus codes.
  3. You get more bonus for your deposit using the exclusive promo codes found on Bojoko.
