Online Casino Bonus Types Explained

Not all casino sites have been created equal, but you can rest assured that the ones listed on CasinoGuide have all been tried and tested to deliver the best gaming experience possible. Before you get started, take a look at our individual casino reviews to discover what's in it for you. 

Deposit Bonuses

mobile casinos

Deposit Bonuses are the most popular casino bonuses due to their simplicity. Deposit bonuses, or matched bonuses will reward you with additional funds simply for making a deposit. For instance, a 100% deposit bonus up to £100 will award you with double the amount of your depositing amount.

In other words, if you deposit £100, an additional £100 will be handed to you in bonus money, bringing the total up to £200. It’s pertinent to note that you are not obliged to deposit the maximum amount of £100 but can deposit any amount (up to £100) and see your deposit double.

No Deposit Bonuses

live casinos

No deposit bonuses are highly sought after as players will be awarded free casino cash without having the need to deposit a penny. No deposit bonuses are significantly smaller than deposit bonuses and you should be aware of online casinos brandishing unusually large amounts of no deposit bonuses.

Essentially, the funds given away through no deposit bonuses is not free to online casinos, hence the reason for smaller amounts given away. All casino bonuses come with a set of terms and conditions that need to be adhered to for the bonus to remain active.

It’s always a good idea to claim no deposit bonuses, regardless of the amount given away. Think of it as a way get acquainted with the casino site and a way to test some casino games on the house. Anything you win is yours to keep, as long as the wagering requirements are met.

Free Spins Bonuses

Free spins bonuses can only be used on Online Slots and can be included as a part of the welcome package offered to new players. Free spins bonuses, or bonus spins as they are sometimes referred to, are the perfect way to spin the reels for free but these too are assigned a set of terms and conditions that stipulate how the bonus can be used.

The terms state what games the free spins can be used on, the value of each spin as well as the timeframe in which they should be used.

Winnings on free spins bonuses are usually capped at a certain amount but this should not deter you from opting in, especially when given away in addition to a deposit bonus when signing up to a casino site.

Reload Bonuses

live casinos

Reload bonuses are specifically aimed at existing players who have recorded a net loss when playing casino games.

Think of it as a helping hand when running a cold streak. A reload bonus will look something like the following: 25% Reload Bonus on all live casino games up to £60. This means that the casino will give you an additional £15 when depositing the maximum amount of £60. 

Reload bonuses or cashback bonuses are usually free of any wagering requirements, since they’re given away after recording losses.

High Roller Bonuses

live casinos

High roller bonuses are essentially the same as any other deposit bonus, with the only difference being that they’re aimed at players with a steeper budget. Some high roller bonuses run into the thousands and have similar wagering requirements to ordinary deposit bonuses.

Loyalty programs or VIP programs are only available to players who would have deposited a significant amount of money to a casino site and will usually be privy to a number of perks for their continued loyalty.

Many VIP programs are split into tiers, with each tier having its own set of advantages. Some benefits of being part of a loyalty program include:

• A dedicated VIP manager to assist you with any desired bets
• Faster Withdrawals
• Bigger and more regular bonuses
• Exceptional customer support


Best Casino Bonuses for UK Players

Money bag graphicPlayers based in the United Kingdom have a plethora of great casino bonuses to choose from. Online gambling remains a popular pastime in Great Britain and many online casinos are vying for the attention of happy punters through various bonus offers. After all, a good casino bonus is what draws new players to sign up at the online casino in question.

Deciding on the best casino bonus first begins with finding out what kind of player you are. Are you a complete newcomer and which to sign up at an online casino for the first time or are you a veteran punter looking for a new challenge? Players who love live casino games can amp up their casino experience with a live casino bonus, or opt for a cashback when that winning streak just doesn’t want to happen. Whatever your style of playing is, there is a casino bonus to match it.

Best Casino Bonuses for new customers

If you’re new to online casino, then the sheer variety of different casino bonuses may feel overwhelming. Which one do you pick? The first type of bonus many new players will encounter is the welcome bonus, which can be claimed after placing your first deposit. This type of bonus can be claimed at a low cost, usually between £10 and £20, and allows the player to take the casino for a test drive. If you’re interested in the best welcome bonus, CasinoGuide has a full list of the very best welcome offers.

No deposit bonuses are also in high demand, whether you’re a new player or not. No deposit bonuses are great to take a casino for a test run before depositing any funds. Don’t expect to get rich off of them though, they’re considered a gesture of goodwill to make new players feel welcome. If you’re a true no deposit hunter, then check out our list of no deposit bonuses for UK players.

If you’re a new casino player, then chances are you’ll be spending most of your time playing slot machines. They’re easy to master, fun and come with their own unique themes, features and soundtracks. Free spins are a great complementary casino bonus for slot players and many of our recommended casino sites offer them as part of their welcome bonus.

Best Casino Bonuses for existing players

Players who have been a patron at their favourite casino for a while, have likely already exhausted their welcome bonus and the package that comes with it. This doesn’t mean that they’ll never get to claim a bonus again, quite the contrary, casino bonuses don't stop after you sign up!

Existing customers can opt in for time-sensitive promotions and tournaments, which are communicated through the online casino’s newsletters or promotions page. Make sure to check your inbox frequently to never miss an update! Tournaments offer a great sense of community with your fellow peers as you battle it out to hit the top of the leaderboard. On top of camaraderie, tournaments also add an extra level of gamification, which is the hottest topic of the online gaming industry these days.

Cashback bonuses can also compliment an existing player’s gambling experience. You don’t need to be high roller or play at high stakes to make a cashback bonus worthwhile. Many online casinos that offer a lifetime cashback bonus, allow the player to stack their cashback returns until they have accumulated enough funds to cash out a large sum.

Reload bonuses great for existing players, they work just like a standard deposit bonus does. The player can make a deposit on certain days of the week and receive a matched percentage bonus or several free spins. Many of our recommended online casinos offer such an incentive in order to keep their existing clientele satisfied.

When to opt for a casino bonus

Woman holding playing cardsNot all casino bonuses you will be presented with need to be claimed. Players can simply choose not to opt in for a particular bonus for whatever reason. A common reason not to opt in for a casino bonus is when you deem the wagering requirements too high, let’s say 50x. This is a very valid reason not to opt in for a bonus, since not every player has that kind of disposable income lying around.

Another reason not to opt in for a bonus is when you deem the maximum win limit too low. Some bonuses are capped with a win limit, which means that you cannot exceed the specified amount. So if you manage to hit a jackpot using the bonus funds, you will not be paid out in full.

Players should only opt in for a casino bonus for the following reasons:

  • You have the necessary disposable income to complete the wagering requirements.
  • You’re okay with forfeiting the bonus funds when you’re unable to complete the wagering requirements.
  • The bonus can be used on a casino game you like to play (for example table games, slots or live dealer games).
  • The casino bonus comes without any wagering requirements (wager-free).

Finding The Best Casino Bonuses

Shopping around is the key to finding the best casino bonuses to suit 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.

Terms and Conditions on Casino Bonuses

Not reading the terms and conditions is a common pitfall for many players. While tedious in nature, giving them a quick once-over is better than not reading them at all. Always make sure you examine the terms and conditions when you accept an online casino bonus offer. To make your life easier, let’s highlight what to look for when reading bonus terms before opting in.


  • Validity: Which games you can play with your bonus. Some casino bonuses, like free spins, can only be used on pre-selected slot games from one software provider. Other casino bonuses, like live casino bonus, can only be used on live dealer games like Roulette and Blackjack.
  • Availability: Time-sensitive promotions can only be claimed during the specified campaign time.
  • Minimum deposit: The minimum deposit required in order to trigger the bonus.
  • Wagering requirements: What requirements you have to complete before being able to withdraw your bonus winnings.
  • Wagering time limit: This is the amount of time the player has to complete the wagering requirements. If the wagering requirements are not met within the given timeframe, the bonus money earned will be forfeited. You will still be able to cash out any winnings made using real money.
  • Time limit: How much time you have to use your bonus before it expires. It is important to know
  • Max bets: Many casino bonus come with a maximum bet that can be placed using the bonus funds or free spins. The limit is in most cases capped at £5.
  • Win limits: Win limits are most tied to free spin bonuses. The win limit determines how much can be won using the bonus funds. For free spins, this is usually capped at £100, even when winning a jackpot.

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.

best online casino bonus wagering requirements

It's smart to know what you're agreeing to when claiming a casino bonus.

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.

  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 some cases.

Casino Bonus Bagging

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.

The average rate of wagering requirements for casinos is around 25-35x, but this is highly variable.

How to play through or rollover a casino bonus?

  1. You take a 100% matched deposit deal with 30x wager requirements.
  2. You deposit £20. The casino therefore credits your account with a £20 bonus.
  3. You wish to play Slots, which has a game contribution percentage of 100%.
  4. You have 30 days to meet the wagering requirements, and there is a max bet of £5.
  5. Your total wager requirements are as follows £20 x 30 = £600. You must wager a total of £600 on a qualifying Slots game before any winnings are eligible for withdrawal.
  6. If you lose, this is no problem as you can choose to stop playing after losing your initial £40, of which you only contributed £20. However, if you make any profit, you must still 'play through' or 'rollover' £600 to withdraw anything you’ve won.

How to withdraw a casino bonus?

To withdraw a casino bonus, first make sure you’ve met all the bonus terms and conditions. In your casino account, the bonus funds and casino credits should be separated, if you are unsure whether you’ve met the terms contact customer support before trying a withdrawal. If you try to withdraw a casino bonus before you’ve met the associated terms and conditions you stand to lose the amount and any winnings associated.

Once you’re certain the terms are met, head to the casino cashier and request withdrawal. Your request should be processed by the casino within 72 hours and arrive in your account when your bank or payment system has registered the deposit.

How to claim a casino bonus?

Each casino will have its own process of claiming a bonus. For some, this means bonus codes, which will be detailed in the bonus terms and conditions on-site or promotional content sent to you via email.

Nowadays, casinos tend to favour automatic application for bonuses, meaning when you’ll either be asked to check a box, opting into a bonus when making a deposit, or the casino will automatically apply the bonus to your account in the case of welcome deals.

How do casino bonuses work?

Casinos offer attractive welcome packages to bring players in, encouraging them to sign up and them ongoing offers such as loyalty points, free spins or cashback to secure your loyalty. Bonuses are one of the best marketing tools casinos have at their disposal.

Essentially, casino bonuses work by the casino giving you the chance to play and win more, but generally, they also include conditions that guarantee you will spend more with the casino than the value of the deal - otherwise known as wagering requirements.

What is casino sign up bonus?

A casino signup bonus is the first awarded to a new player at the casino. It will be applied to the player’s new account when you either register and verify the account (no deposit bonuses) or make your first deposit (matched deposit deals).

Why can't I withdraw my casino bonus?

To ensure that you give value back to the casino (instead of qualifying for a bonus and not playing with the credits), you will be able to withdraw any winnings you make from a casino bonus once you’ve met the terms and conditions in full.

What is a casino reload bonus?

A reload bonus is a matched deposit deal, where the casino matches the amount you deposit, but instead of it being used exclusively as a welcome offer, the reload deal can be applied to all players at any time the casino offers it.

What is the GCP?

GCP stands for Game Contribution Percentage. This number represents how much of your play on a certain game will contribute towards your bonus wagering requirements.

Slots typically have a GCP of 100%, whereas table games like Blackjack and Roulette are often between 5-20%.
