What is a Casino Bonus Code?
Bonus code offers and promotions are a great way for players to get the most out of their regular gambling.
Many of the really great bonus codes make it easy for new customers to sign up with different online casinos and try several slots and games for free.
There’s often no need to deposit any of your hard-earned cash either. Regular players can also try out new video slots and table games at their regular casino with free spins or free bets.
A bonus code is a string of letters, numbers or symbols, it’s that simple! This unique combination can unlock a special offer or bonus when you enter it at an online casino.
Codes can be given to both new and existing players for a range of special bonuses. We’ll look in more detail at each type of bonus you can expect as a new or existing online casino player.
Welcome Bonus Codes for New Players
As a new player, signing up at an online casino for the first time, you can expect to find some great deals. However, some of the best welcome offers are only accessible via exclusive bonus codes. Therefore, it’s very important to check that you are getting the best deal any casino has to offer before creating a new account.
Some of the bonus deals offered to new casino players can be extremely valuable and contribute to the fun and excitement of online gambling. Ultimately, if you can play some games for free, you have opportunities to check out gameplay, rules and whether you actually enjoy them.
Free Spins Codes
Some codes can give you free spins on selected slot games. These can range from just 5 free spins up to 50 or possibly more. The casino will usually specify which slots can be played using the spins.
So, it’s not possible to use the free spins to play any video slots you fancy.
Cash Match Bonus Codes
You can get some extra bonus cash to play with using a special cash match bonus code. The code can be applied when you make your first deposit. It will trigger the casino to match your deposit at a specified percentage, up to a max amount.
For example, a code for a 100% cash match up to £100 would give you a maximum of £100 in bonus cash when you make a deposit of £50.
No Deposit Free Spins
You can play selected slots before you make a deposit with a no deposit free spins code. Entering this code when signing up will credit your account with a lump of free spins.
They are usually valid on specified games only but are a great way to play casino games for free.
Live Casino Bonus Codes
Fans of table games can use live casino bonus codes to play games for free. Entering one of these codes can give you some free live casino credit.
Offers typically give £5, £10 or £20 of live casino bonus funds to enjoy. These codes can be valid on selected table games only, like roulette or blackjack.
Bonus Codes for Existing Players
As an existing player, it’s important that your loyalty to any online casino is always well rewarded. Thankfully, casinos often dish out bonus codes for existing players to keep them sweet. These bonus codes are usually valid for a similar range of bonuses to those mentioned above. The important thing is knowing where to find them once you’ve used up all your welcome bonuses. Here’s how to get your hands on some rewarding bonus codes as an existing player.
Opt-in Only Promotions
It’s a great idea to regularly check the promotions page when you are logged in at any online casino.
Some sites will tailor their bonuses based on your activity and it’s a great place to find some exclusive opt-in only codes.
You might also see offer codes appearing in your account section or ‘inbox’ on a casino site. Be sure to check there regularly.
SMS or Email Codes
To take full advantage of any exclusive codes, ensure you’re signed up to the casino’s promotional emails or SMS.
Gambling sites will often tailor casino bonus offers based on your playing style and send them to you directly.
Check your contact preferences in your account settings to ensure you don’t miss out.
VIP Promotional Codes
If you’re part of a casino’s VIP programme then you can gain access to bonus offers that regular players just don’t get.
Expect to receive some exclusive bonus codes that are tailored to your specific interests.
How to Find the Best Casino Bonus Codes
You’ll need to seek out a bonus offer that appeals to you. That might involve free spins, bonus cash or credit for live casino games.
Check the exclusive CasinoAdvisors offers at the top of this page to get started quickly.
If you don’t have an existing account at the online casino with the offer you want, it’s easy to create one.
Signing up takes just a few minutes and should require some basic personal information.
Check where you need to input the code to claim the bonus offer. This might be during signup or when you make your first deposit.
It’s important not to miss this step, otherwise, you will not be credited with the bonus.
Once the bonus is active on your account, you can enjoy using it to play selected casino games. Be aware of the wagering requirements attached to any bonus offer.
These will need to be fulfilled before you can withdraw your winnings.
Why Do Casinos Offer Bonus Codes?
Competition between online casinos is fierce, which is great news for all players. Casinos are constantly trying their best to attract new players and keep existing ones interested. Dishing out bonus codes is just one of the ways they can achieve this.
Offering limited-time freebie codes creates a sense of urgency to claim the latest offers. Providing codes to loyal players can also encourage them to deposit more cash and play frequently. Online casinos can quickly build loyalty with new players this way.
Bonus codes are also a good way for casinos to introduce new slots and games on their platform. Offering promo codes for specific games will ensure they are played from the moment they are launched.
Frequently Asked Bonus Code Questions
Casino’s will usually place restrictions on withdrawing winnings made from bonus cash offers. These are known as wagering requirements and can range anywhere from 20x to a 500x play through rate.
Receiving £10 of free play at a 50x play-through rate, you would need to play at least £500 before being allowed to withdraw any winnings.
This depends on what type of games you enjoy playing. There are bonus codes out there to suit all tastes and playing styles.
If you like slots, table games or something else, simply choose the codes that offer freebies for that game type.
Yes you can. Bonus codes can give you free spins, cash matches or casino credits as a reward. The winnings will usually be paid out as real money, but wagering requirements might apply.
That’s why it’s always best to fully check the terms of any bonus code offer to ensure you can access your winnings.
