Popular Types of Casino Bonuses
Online casinos offer a variety of welcome bonuses, and it can sometimes be overwhelming—especially if you’re new to online gambling. Below, we break down the different types of casino bonuses and explain how each one works.
Deposit Bonus
Most online casinos offer a deposit bonus as an incentive for new players. A 100% deposit bonus, for example, means that the casino will match your first deposit with an equal amount in bonus funds. A 200% bonus will double your deposit, while a 50% bonus will provide half of your deposit amount as bonus money.
It’s important to note that bonus funds cannot be withdrawn directly—they are only available for playing games on the site. Once you’ve used your bonus money, any winnings will be subject to wagering requirements, which must be met before withdrawal is possible. Further details on wagering requirements are provided later on this page.
No Deposit Bonus
While there’s no such thing as truly free money, no deposit bonuses used to be a popular way for casinos to attract new players. These bonuses allowed users to receive a small bonus simply by registering an account—without needing to make a deposit.
However, no deposit bonuses often came with high wagering requirements, which meant players had to wager a significant amount before they could withdraw any winnings. Due to this, such offers have become less common, and it may now be difficult to find a no deposit bonus at online casinos.
Free Spins
Free spins promotions allow players to spin slot reels without using their own money. Each free spin has a predefined value, typically around £0.10. Some free spin offers are limited to a specific slot game or a selection of new online slots, while others may be valid for a broader range of games.
Free spins usually have an expiration period, meaning they must be used within a set timeframe. Any winnings earned from free spins are typically credited as bonus funds, which can only be used once the wagering requirements have been met.
Cashback Offers
No matter how lucky you are, some days just won’t go your way. If an online casino offers a cashback promotion, you can recover a percentage of your losses over a certain period.
For example, if a casino has a 20% cashback offer, it will return 20% of your total losses for the previous week. However, there is usually a minimum loss threshold that must be met. If you lost £30 during the week, you would receive £6 in cashback.
Most casinos provide cashback as bonus funds, meaning wagering requirements may apply. However, some casinos offer cashback as real cash, which can be withdrawn immediately without restrictions.
Loyalty Bonus
Online casinos appreciate players who return regularly rather than those who sign up just to claim a welcome bonus and leave. If you’re a frequent player at an online casino, you may receive rewards for your loyalty.
These bonuses are personalized and typically sent directly to your casino inbox. They may include deposit match offers, free spins, exclusive cashback deals, or other special promotions designed to keep loyal players engaged. The best online casinos in the UK make it a priority to reward their returning customers.
Refer a Friend
If you’ve discovered an exciting online casino with great promotions, you might want to share the news with your friends. Many online casinos offer a refer-a-friend bonus as an incentive for bringing in new players.
However, simply telling a friend about the casino isn’t enough to claim this bonus. To qualify, your referred friend must sign up and make a minimum deposit. Once they’ve completed these steps, your referral bonus will be credited to your casino account.
No Wager Bonus
Most casino bonuses come with wagering requirements, meaning you must play through a certain amount before withdrawing any winnings. However, some casinos offer no wager bonuses, where any winnings you earn from the bonus funds are added directly to your account as real cash.
This type of bonus allows you to either continue playing or withdraw your winnings immediately, without any wagering restrictions. While these offers are rare, they are highly sought after by players looking for more flexibility.
Multi-Part Bonus
Some deposit bonuses are structured as multi-part bonuses, meaning players can claim rewards across multiple deposits. Depending on the casino, a bonus may be spread over the first two, three, or even five deposits.
For example, a multi-part bonus could be structured as follows:
- First deposit: 100% bonus up to £250
- Second deposit: 50% bonus up to £250
- Third deposit: 25% bonus up to £250
- Fourth deposit: 100% bonus up to £250
Each bonus segment typically has the same terms and conditions regarding minimum deposit amounts, wagering requirements, and expiry dates. As always, it’s important to read the terms of any promotion to understand the conditions fully.
Most online casino promotions come with wagering requirements, which can sometimes be confusing for new players. Here, we’ll break down what they mean and how they work.
Wagering requirements exist to prevent casinos from giving away free money without any restrictions. Without these requirements, online casinos would risk financial losses by allowing thousands of players to withdraw bonus funds instantly.
How Wagering Works:
Wagering requirements are typically expressed as a multiple of the bonus and/or deposit amount.
For example:
- A £100 deposit bonus with a 35x wagering requirement on the bonus only means you need to wager £3,500 before withdrawing winnings.
- If the requirement applies to both the deposit and bonus, the total wagering needed would increase to £7,000 (35x £100 deposit + 35x £100 bonus).
Game Contributions to Wagering:
Not all games contribute equally toward meeting wagering requirements:
- Slots & Scratchcards – Typically contribute 100%. If you wager £1, the full £1 counts toward the requirement.
- Casino Table Games – Usually contribute only 10%. If you place a £1 bet in blackjack, only £0.10 goes toward the wagering requirement.
By law, every casino must offer at least one game that contributes 100% to wagering.
Real-World Example of Wagering:
Let’s consider a 200% Welcome Bonus up to £7,500 + 10% Cashback.
- A player deposits £1,000 and receives a £2,000 bonus, totaling £3,000 in playable funds.
- The bonus terms state that every 15x wager of the deposit releases 25% of the bonus.
- So, once the player wagers £15,000, they receive £500 of the bonus.
If only slots contribute 100%, a player could meet the wagering requirement by spinning 3,000 rounds at £5 per spin. By the end of the session, they might have built up £17,000 in winnings, plus the unlocked £500 bonus!
To fully unlock the entire £2,000 bonus, they would need to repeat this process three more times.
Understanding wagering requirements is key to making the most of casino offers, ensuring you know exactly what’s needed to turn bonus funds into real, withdrawable cash.
Restricted Payment Methods for Casino Bonuses
Before claiming a casino bonus, it’s essential to check if any payment methods are excluded. Many online casinos impose these exclusions to prevent individuals from abusing welcome offers by creating multiple accounts.
Commonly excluded payment methods include eWallets and cryptocurrencies, as they allow for quick and anonymous transactions. On the other hand, debit cards and bank transfers are rarely excluded, as opening multiple bank accounts just to claim a bonus is highly impractical.
To ensure you receive your bonus, always use an eligible payment method when making your qualifying deposit. Otherwise, you may find that your bonus is not credited to your account.
How to Recognize a Valuable Casino Bonus
Not all casino bonuses are created equal. Some provide great value, while others come with restrictive terms that make them almost impossible to benefit from. So, how do you distinguish between a worthwhile casino bonus and one that’s best avoided? Here are a few key factors to consider:
Maximum Bonus Value
A good casino bonus should offer realistic value. If the maximum bonus is too low—for example, £20 or less—it may not be worth your time. Conversely, if a casino is advertising an extremely high bonus (such as a 400% match up to £25,000), it’s likely tied to unfavorable terms and conditions, making it difficult to claim the full amount.
By carefully evaluating bonus amounts and their conditions, you’ll quickly learn to identify genuine value in casino promotions.
Minimum Deposit Requirement
The minimum deposit requirement should align with your budget. Just because a casino offers a generous bonus doesn’t mean you should be forced to deposit more than you’re comfortable with.
For instance, if you’re only looking for a £20 bonus, but the promotion requires a £50 minimum deposit, then it may not be the right choice for you. Always check this requirement before committing to a deposit.
Wagering Requirements
While wagering requirements are standard in casino bonuses, some are far more reasonable than others.
An ideal wagering requirement is around:
- 20x for both the bonus and deposit
- 40x for either the bonus or the deposit
Bonuses with requirements much higher than this tend to be less valuable, as they make it significantly harder to withdraw any winnings.
Gaming Freedom
A casino bonus should offer flexibility in the games you can play. Most casinos allow bonus funds to be used on slots, as they contribute 100% toward wagering requirements. Since most casinos offer over 1,000 slot games, this isn’t usually an issue.
However, problems arise when casinos limit bonuses to only a few specific slots or, even worse, a single slot game. The best casino bonuses allow for a wide variety of game choices with minimal restrictions.
Maximum Bet Limit
A commonly overlooked bonus restriction is the maximum bet value during wagering. Some casinos set a strict maximum bet limit, which can significantly slow down your wagering progress.
For example, if you need to wager £10,000 within three days, you might plan to place 2,000 spins at £5 each. But if the bonus terms limit bets to £0.10 per spin, you would need to place 100,000 spins—a nearly impossible task within the given timeframe.
Always check for betting restrictions in the terms and conditions before claiming a casino bonus. The best offers will have reasonable betting limits that allow you to complete wagering without excessive limitations.
Excluded Bets
Another important detail often hidden deep in the terms and conditions of casino bonuses is the concept of excluded bets. These are specific betting actions that are not allowed when using bonus funds.
Examples of excluded bets include:
- Doubling down in blackjack
- Betting on red/black in roulette
- Playing live casino games
If you place an excluded bet—even by accident—your bonus may be voided and removed from your account. Always check the T&Cs carefully to avoid accidentally breaking any hidden rules.
Maximum Winnings
Most UK online casinos impose maximum winnings limits on bonuses. This ensures that the casino does not suffer heavy financial losses if a player wins an exceptionally large amount using bonus money.
Typically, a fair cap on winnings is around 10 times the bonus amount. For example, if you receive a £1,000 bonus, the maximum amount you can withdraw from bonus-related winnings is £10,000. Any winnings above this limit will be voided and returned to the casino.
Time Limits
Casino bonuses are time-sensitive, meaning you must meet all conditions within a specific timeframe. There are usually three key time limits to keep in mind:
- Claiming the bonus – Some casinos require you to claim the bonus within a set time after signing up.
- Using the bonus – You must use your bonus funds within a certain period, or they will expire.
- Meeting wagering requirements – Wagering must be completed within the given time, or the bonus and any winnings will be forfeited.
Some casinos enforce tight time limits, sometimes as short as 24 hours, making it difficult to meet wagering requirements. A more reasonable period is seven days, giving players enough time to fully use their bonus.
Maximizing Your Casino Bonus Benefits
Want to maximize your casino bonus? Follow these expert tips to get the best possible value from your bonus funds.
- Don’t Max Out the Bonus Just Because You Can: Many welcome bonuses offer high limits, sometimes up to £1,000 or more. However, you should only deposit an amount you’re comfortable with. There’s no point in depositing more than you can afford just to claim additional “free” bonus cash.
- Read the Terms and Conditions Carefully: Never claim a casino bonus without fully understanding the T&Cs. Some conditions can significantly impact your ability to withdraw winnings. Always read through the terms twice to ensure you’re aware of any restrictions.
- Use High-RTP Slots for Wagering: If you’re serious about clearing a casino bonus, slots are your best choice for wagering. Slots contribute 100% to wagering requirements, unlike table games, which often contribute only 10%. Always choose high-RTP slots (Return-to-Player percentage) of at least 96%, as they offer better long-term value.
- Don’t Try to Withdraw Too Soon: If you land a big win early on, resist the temptation to cash out immediately. Nearly all bonuses have a wagering requirement, meaning you must complete the required playthrough before making a withdrawal. If you attempt to withdraw early, you may forfeit all bonus winnings.
By following these strategies, you can maximize your bonus and increase your chances of turning it into real, withdrawable cash.
Exclusive Casino Promotions for Returning Players
While welcome bonuses are designed to attract new players, top online casinos also focus on keeping existing players engaged. The best casino sites offer reload bonuses, which work similarly to welcome bonuses but can be claimed multiple times instead of just once.
Other promotions for existing players include:
- Loyalty Bonuses – Rewarding players who wager a certain amount within a qualifying period. These can include free spins, deposit matches, or exclusive deals.
- Cashback Bonuses – A percentage of your weekly or daily losses refunded as bonus cash. However, cashback is often subject to wagering requirements before withdrawal.
If you’re a regular player, it’s worth looking for casinos that offer ongoing promotions to ensure you get rewarded for your loyalty.
Reasons to Take Advantage of Casino Bonuses?
One mistake players often make is expecting to get rich from casino bonuses. While it’s true that some players have won large amounts using bonus funds, this shouldn’t be your main reason for claiming them.
Instead, casino bonuses offer other valuable advantages. Here are three key reasons why using them makes sense:
Test Drive a Casino
Many casinos allow you to play for free, but the real excitement comes when you play for real money. Instead of risking your own funds at a casino you’re unfamiliar with, you can use bonus money to test out the platform.
By the time you’ve used up your bonus cash, you’ll have a better idea of whether the casino is worth continuing to play at.
More Money to Play With
Why start playing at a new casino with just £20 when a bonus could allow you to play with £60 or more? Even if you don’t plan on meeting the wagering requirements or cashing out winnings, having extra funds allows you to play for longer and enjoy more games.
Explore New Games
With thousands of slot games and hundreds of table games, chances are you haven’t played them all. You might hesitate to try a new game with your own money in case it’s not as exciting as expected.
Using bonus money allows you to test new games risk-free. If you don’t enjoy the game, you haven’t lost anything. But if it turns out to be a new favorite, you can then decide whether to wager your own money on it.
By understanding how casino bonuses work and using them wisely, you can make the most out of your online casino experience while minimizing risk.
