Casino bonus offers don't stop after you sign up!

Apart from the online casino deposit bonus, there are several other types of casino bonus online.

It is true that many online casino welcome bonus deals can look very similar at first glance. However, these casino signup bonus offers often have varied wagering requirements which change the ways that they should be used.

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.

Post Sign Up Bonuses

Already collected your casino signup offer, online casino deposit bonus, and begun playing? You could be forgiven for thinking that's all the online casino bonus offers you can expect.

In this case, you could find yourself pleasantly surprised! Some Bonus Casino sites also offer countless more special deals that are only available once registered. Among others, these can include: account reload bonuses, loyalty bonuses, and even referral bonuses!

Reload bonuses are similar to welcome bonus casino UK operators boosting your account balance when you initially sign up. Essentially, these smaller bonuses are a form of online casino deposit bonus. They are usually activated or offered to youonce you deposit additional money into your account.

You can also expect to receive casino bonus codes via email. These are often designed to reignite your interest in playing after a period of non-participation.

Types Of Online Casino Bonus Offers

While browsing Bonus Casino sites, 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 This casino bonus 'sticks' to your deposit, meaning it can’t be withdrawn from your account.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 Bonus 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.


Casino Sign Up Offer: What To Look For

Shopping around is the key to finding a Bonus Casino 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.

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 definitely a game worth playing.

Never forget to check the fine print of any online casino bonus 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.


Online Casino Bonus Types Explained

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.

 

Sticky Bonus

As you make your deposit and receive your bonus, the deposit becomes automatically combined with the bonus. You can only withdraw your casino balance after completing the wagering requirements.

 

Non-Sticky Bonus

Your deposit is always available to be withdrawn, regardless of the bonus. When you start playing in the casino, your deposit is used up first. If/when that runs out, you move onto your bonus.

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 most generous online casino bonus you get will probably be your casino joining bonus. This is because welcome bonus casinos want you to have the most positive first impression possible.

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 from casino to casino, 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

Casino Bonus Wagering Requirements

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, not only from casino to casino, but even from bonus to bonus within a single casino. Typically, they only apply to the Welcome Bonus, but it is always wise to check the terms for yourself to be sure.

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.

1

You make a deposit of £20 into your new online casino account right after signing up.

2

The casino gives you a £20 bonus to thank you for signing up and making a deposit.

3

 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:

£20 x 30 = £600

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

Good to know
When you are playing with a sticky bonus, calculate using the deposit + the bonus, as they are bundled in together in these cases.

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.
