Overview

There are hundreds of online casinos out there, and almost every single one of them offers special promotions and bonuses. Quite often, you will need to use a bonus code to claim a particular promotion you're interested in.

These bonus codes are special coupons designed for different occasions, such as rewarding loyal customers or welcoming new players to the site.

How Do Bonus Codes Work?

To claim different online casino promotions and bonuses, you'll need to complete certain actions and take some steps. One of the most popular ways to claim free spins or bonus money is by using a bonus code when signing up for a casino account.

Most casinos will give out unique bonus codes for players to use to take advantage of a particular offer on the table. Most of these codes are only available to new players, but some operators also go out of their way to ensure generous rewards for regular loyal players as well.

Best Bonus Code Deals

Some deposit match offers will come with a casino bonus code you'll need to use. In general, players can claim a higher match with the bonus code, which gives them more additional funds to play with without requiring them to risk more money.

However, by far the most popular types of offers sought by the players are free spins and no deposit bonus codes, providing some free play funds without any monetary risk.

Using a no deposit bonus code, you'll be able to get some cash in your casino account immediately after registering, and, as the name suggests, no deposit is required.

Even so, you'll still need to register for a casino account and enter the correct bonus code when asked for it. You should also know that most no deposit bonuses have fairly high wagering requirements, so always take the time to read the terms and conditions to avoid problems or surprises later down the line.

Bonus codes for free spins work in a similar way. After activating the bonus code, the player receives a certain number of free spins to use on a particular slot or a select group of slots. The money won is usually added to your bonus balance and has wagering requirements attached to it.

Every now and then, though, you will find a free spins bonus code that will let you play, win, and keep all the winnings as real money without any restrictions. These offers are by far the most popular with the players, but they are quite rare.

Those looking to spice things up with bonus codes should keep an eye out on the casino's promotions page. This is where you will find the updates about all the latest deals, offers, and special promotions up for grabs.

Know Your Wagering Requirements

Almost every time you use a bonus code to activate an offer, there will be certain terms and conditions attached to it, and wagering requirements are the most important ones. These tell you how much you need to play before the bonus funds are converted and available for withdrawal.

In general, wagering requirements will be in the 25x to 50x range. Some online casinos can have slightly higher or lower wagering for some offers, though, so always make sure to check.

Whatever the wagering requirements may be, they will apply either to the full amount (bonus + deposit) or just the bonus cash. To give yourself the best winning chances, look for offers with low wagering that you can beat within time restrictions that usually come attached to casino bonuses as well.

For example, if you get a bonus of 5,000kr and wagering requirements are set at 10x, you will need to place 50,000kr worth of bets before bonus winnings are transferred to your real-money balance.

Getting Most Out of Casino Bonus Codes

Almost all bonus code offers will appear quite generous at first. However, to gauge their true value, you need to dig deeper and look into all the relevant terms surrounding the offer. Only then will you be able to tell if it is actually worth your time and money.

Check out for things such as the minimum amount needed to activate the bonus, how long you'll have to beat the wagering, are there any limitations in terms of games you can play, etc.

Often, bonuses can be used only on a certain type of game.

Bonus codes for slots, for example, will only allow you to use the extra funds on slot games, with further potential limitations in terms of games or providers. Play on other games may not count towards wagering, or it could be completely forbidden while the bonus is active.

To get the most out of casino bonus codes, look for the ones with the best and most player-friendly conditions in all of these areas.

How to Get Started

Here's how you can claim the first Casino Bonus Code: Follow these simple steps to get started with casino bonus codes and claim your bonus offer within minutes:

1 Pick a Casino With a Bonus Code

3 Deposit Funds

4 Jump into the Action

Your bonus funds should be added shortly, and you can proceed to the games section to start playing. Stick to the games that contribute to wagering requirements, and make sure you don't play any games that are explicitly listed as forbidden under the bonus terms and conditions.
