Finding the Best Online Casino Bonus
Shopping around is the key to finding the best online casino bonus which suits your needs. Remember: online casinos are ready, willing and able to tempt you with a highly generous online casino signup bonus. In doing so they hope that you try out their site for the first time and like it so much you come back again. That's why it's wise to find the best deposit bonus casino you can.
Slots promotions, for example, can be very lucrative indeed. You can find out if playing Slots is your jam by trying our free casino Slots game, here on CasinoGuide (no signup necessary). When it comes to making the most of your online casino bonus, Slots is probably the most lucrative of all casino games.
Never forget to check the fine print of any online casino bonus or casino promotions that you receive. For example, collecting a casino bonus (Slots only) promotion naturally implies that you will only be allowed to receive your casino bonus by playing Slots.
One cool new feature that is gaining traction in the casino bonus world is the concept of offering players a choice between several different bonuses. For example: 500% match on deposits up to £100, or 300 free spins on selected Slots games. One of the Casino Room bonus offers gives you just such a choice.
Apart from the first deposit bonus, there are several other types of casino bonus online.
It is true that many online casino welcome bonuses can look very similar at first glance. However, even the best online casino bonus offers often have varied wagering requirements which alter how they can be used. As these can sometimes be very confusing, casino bonus offers are heavily scrutinised by the UK Gambling Commission.
For example, one online casino bonus may stipulate that a certain percentage be used on playing Blackjack. The most common online casino bonus requirement is that it is spent on Slots. The same applies if you are claiming a Bingo bonus or using Virtual Casino bonus codes.
Types Of Online Casino Bonus Offers
While browsing our list of the best online casino bonus offers, you might find an online casino bonus known as a 'sticky bonus'. This casino bonus 'sticks' to your deposit, meaning it can’t be withdrawn from your account. However, the bonus amount can be used to play games and win real money casino games.
On top of that, any winnings that you accumulate are yours to keep. Just remember to subtract the casino bonus amount from your account balance when calculating amount you can withdraw. Some casinos will actually show this as a separate amount for your convenience.
Looking for an online casino bonus that will reward you for playing on your mobile device? Whether you play via your browser or by downloading the app, you need to check our list of mobile casino bonus offers.
Have all the different terms for all of the various online casino bonus offers got you confused? You're not alone if so. Which is why we have put together this useful glossary!
The first thing to understand is that all online casino bonuses fall into one of two categories; sticky, or non-sticky.
Welcome Bonus (AKA Signup Bonus / First Deposit Bonus)
Another name for the casino signup bonus. The online casino welcome bonus is a token of appreciation from your bonus casino of choice, to thank you for choosing to play with them.
Many players choose to stay with the bonus casino they first play at. The biggest and best online casino bonus you get will probably be your casino joining bonus. This is because they will want you to have the most positive first impression possible - particularly if it's a high roller casino.
You'll have the most success if you are planning to make a deposit shortly after signing up. Biting your nails at the thought of making your first deposit and playing for real money? You should definitely look into a no deposit bonus casino. These will enable you to play at a proper online casino just by using your casino sign up offer.
Other Bonus Information
As well as knowing the above bonuses, you will also want of be aware of a few miscellaneous ones:
- Bonus codes - usually sent via email to existing players
- Deposit match - a percentage of your deposit given as a bonus
- Reload bonus - a bonus given for making additional deposits
Casino Bonus T&Cs
Always make sure you examine the terms and conditions when you accept an online casino bonus offer. These can very a great deal between online casinos, and can affect things like:
- Which games you can play with your bonus
- What requirements you have to complete before being able to withdraw your bonus winnings
- How much time you have to use your bonus before it expires
One of the most important things to be aware of when claiming an online casino bonus, is its wagering requirements. This is what dictates how many times you need to 'play through' your bonus, before you are able to withdraw your balance and all of the winnings within.
Wagering requirements vary between all real money casinos online, and even from bonus to bonus within a single casino.
They can seem a little bit daunting and complicated. But the calculations for figuring out a casino's wagering requirements are simpler than they appear. It's easiest to get your head around it by using an example.
- You make a deposit of £20 into your new online casino account right after signing up.
- The casino gives you a £20 bonus to thank you for signing up and making a deposit.
- The wagering requirements of that bonus are x30, meaning the money has to be 'played through' 30 times.
Once you know this, the calculation is simply: bonus x wagering requirement. So in this case:
This means, you will need to bet at least £600 before you are able to cash out your bonus. This amount is known as your 'play-through' requirement.
What Is The Game Contribution Percentage (GCP)?
This is the final piece of information you need to know before you start spending your bonus money. The GCP is the proportion of your bets that count towards your bonus 'play-through' requirement, and it varies from game to game.
Typically, online Slots games have a GCP of 100% - casinos rely on the house edge and lack of strategy to ensure their profit margin.
On the other hand, table games that involve more strategy, such as Blackjack and Roulette, will typically have a GCP of 10-25%.
Once you know this other crucial piece of information, you simple divide the play-through requirement by it:
- Slots: £600 / 100% = £600
- Blackjack: £600 / 15% = £4000
When you are playing with a sticky bonus, calculate using the deposit + the bonus, as they are bundled in together in some cases.
Some casinos offer casino bonus codes to new and existing users, as a way of redeeming special types of casino bonus. While everyone loves an online casino bonus, it can sometimes be a hassle to remember casino bonus codes, which is why we have saved you the trouble here on CasinoGuide.

Specific Online Casino Bonus Codes
Want to see the different casino bonus offers provided by a particular online casino? You can find this information in our in-depth casino reviews. Any casino room bonus code that you may need at each particular casino can be found there as well.
You may choose to receive online casino bonus codes on a regular basis once you're signed up at your choice of bonus casino. Casino bonus codes and reload bonuses often appear in promotional emails and other messages.
These are among the most common methods that a bonus casino will use in order to retain as many long-term players as possible.
Casino Bonus Bagging is a means of obtaining favourable online casino bonus deals often employed by advanced and experienced bonus casino players.
'Bonus Baggers' (as they are known) are always on the hunt for the best online casino bonus which they can use to turn into pure profit.
Fundamentally, Bonus Baggers will only play and invest their money in certain online casino games. Namely, those which they are absolutely sure will yield a considerable profit from their online casino deposit bonus and casino signup bonus.
Clearing Your Online Casino Bonus
Knowing how and when you will 'clear' your online casino bonus is important. This is the point at which you have met all wagering requirements and are free to withdraw your account balance.
If your favourite game is Slots, then obviously the first priority is to enjoy yourself whilst playing the game. You may find that you meet your wagering requirement and clear your casino bonus without even intending to do so.
At this point you have the choice of carrying on, or withdrawing your balance. How you withdraw your balance will depend on the casino payment options available.
