Types of Casino Bonuses at UK Sites
Top online casinos in the UK offer a variety of bonuses to both new and existing players. While each casino has its own promotions, the most common types include the following:
Welcome Bonuses
Welcome bonuses are promotions that are exclusively available to new players when you first join a casino. As they try and encourage you to sign up, they’re often among the biggest and most generous rewards offered by a casino site, and generally involve a combination of a deposit match, free spins and/or cashback.

Free spins give you the chance to win cash playing online slots without having to wager real money bets for a specified number of spins. These are normally offered on the most popular or newest slot games available at a casino site, and can feature no deposit free spins, no wagering free spins and daily free spins.

Minimum deposit casinos offer bonuses designed for players on a budget, by allowing you to claim deposit matches and free spins with £10 or less. These bonuses can be useful for trying out new casinos at limited cost to your wallet, and are available at numerous sites across £1 casinos, £5 casinos and £10 casinos.

Some casinos run no deposit bonuses, whereby you don’t have to deposit any money at all to claim the promotion. Instead, you simply need to opt in or enter a bonus code, or it may be automatically credited to you once you’ve signed up. As a result, no deposit bonuses tend to have stricter wagering requirements.

Deposit match bonuses give you extra money on top of your deposit, by a specified percentage and up to a maximum limit. For instance, if you claim Jackpot City’s welcome offer of a 100% match of up to £100 and deposit the same amount, the casino will effectively double your deposit so you have £200 to play with.

Cashback bonuses return a percentage of your losses on certain games over a set period of time. As an example, All British Casino offers 10% cashback on every deposit you make for 24 hours, so if you lose £100 in the 24 hours after a deposit, you get £10 back. Cashback rewards can help your bankroll last longer as you play real money games.
Get 10% cashback at All British CasinoVIP and Loyalty Schemes
Many casinos run loyalty programmes for regular players, which allow you to unlock award extra bonuses and perks. These can involve different tiers or levels, which give out increasing rewards as you deposit and wager more money. VIP schemes are common at high roller casinos, which are popular with online gamblers willing to bet large amounts.

All bonus types sometimes require you to enter a bonus code to activate the offer. You may have to do this as you’re making a deposit, or from your casino account settings. As an example, to claim Winomania’s welcome bonus of 100% up to £100 plus 100 free spins on Big Bass Splash, you need to make your first deposit using the bonus code WINO100.

There are dozens of UK online casinos to choose from, which means by extension there are lots of bonuses available to players. As with many things when it comes to gambling online, some are better than others, so it’s important to know how to spot a bonus which is worth your time and money.
When reviewing the bonuses available at a casino, here are the things we look out for before recommending them to you:
Valid Licensing: If a casino has legit licensing from the Gambling Commission (UKGC) and Malta Gaming Authority (MGA), that means it can be trusted to provide the bonuses it advertises. Irrespective of the bonuses available at a casino, we recommend avoiding any operator that is not UKGC-licensed.
Reasonable Wagering Requirements: A bonus can seem generous at first, but may make it difficult to withdraw any winnings via restrictive wagering terms. Generally, wagering requirements of 30x and lower can be considered generous, while 50x and higher are strict.
High Maximum Win Limit: A casino bonus is no good if it gives you lots of extra money to play with, but then harshly caps what you can win from it. Ideally, the maximum win limit should be at least five times the bonus amount, giving you the opportunity to convert your bonus into massive wins.
Good Games Eligibility: A benefit to claiming bonuses is that they can give you a better feel for the games collection at a casino. The best bonuses can be used on a wide range and large number of titles, meaning you’re not constrained to a limited selection of games.
Advantages of Online Casino Bonuses
The most obvious advantage to claiming and using online casino bonuses is that they give you more money to play with and therefore, more chances to win. However, there are other benefits to casino bonuses as follows:
- Casino bonuses can offer a good way to try out new casinos and the games they have on offer without having to make a big deposit. By utilising deposit matches and cashback, you can better gauge the overall quality of a casino’s games library while being able to risk less of your money.
- Promotions are a good way to get the most out of online gambling if you’re playing on a budget. No deposit offers and free spins give you risk-free chances to win, while deposit matches allow you to play for longer when you add money to your account.
- Bonuses can be useful for discovering new games and titles that you enjoy playing. For instance, if you mostly play live casino titles, free spins may help find you fun slots that you would otherwise never normally try.
Casino Bonus Terms and Conditions
Promotions at real money casinos come with T&Cs that we suggest you check and read through before claiming the promotion. These can dictate what you need to do to get the bonus and which games it can be used on and, more importantly, how hard it may be to cash out any winnings:
⏰ Time Limit
Casino bonuses have a time limit, which states how long you have to use the bonus and complete any wagering requirements. If the time limit expires before then, you will lose any bonus funds or free spins and winnings you have earned from them.
📋 Wagering Requirements
Bonuses normally have wagering requirements. These dictate how many times you must play through any winnings before the casino will allow you to withdraw them. If you win £10 from a bonus with wagering requirements of 30x, for instance, you’ll need to wager £300 using your winnings before they can be withdrawn.
🪙 Minimum Deposit Amount
When you’re claiming a promotion that is activated by a deposit, the casino will specify the minimum amount of money that you need to deposit to your account. In most cases, this is between £5 and £20.
💳 Payment Method Restrictions
Some casinos only allow to you to get bonuses when you deposit using certain payment methods among those they accept. Most commonly, e-wallets and prepaid vouchers are prohibited from claiming promotions, as they make it harder for the casino to verify your identity.
🤑 Maximum Win Limit
A casino can impose a maximum win limit on a bonus, meaning you can’t win any more money from the promotion than the specified amount. As an example, if you win £80 from a deposit match bonus with a max win of £50, the casino will only give you £50.
🎰 Game Restrictions
A casino bonus can often only be used on a specific type of game or certain titles within that. For instance, free spins are only eligible for online slots, while a gambling site may run promotions specifically for RNG table games or live casino titles.
Why Do Casino Games Contribute Different Amounts to Bonus Wagering Requirements?
Jon Young, Bonuses Expert: “You may notice in a casino’s bonus T&Cs that bets on different games contribute a different percentage of your wagers towards playthrough requirements. For instance, wagers on slots normally contribute the full amount, whereas bets on table games such as blackjack and roulette may only count for 50% or less, or not at all.
This is because table games and live dealer titles tend to have higher return to player (RTP) rates than slots, so casinos introduce rules such as this to encourage you to complete wagering requirements by playing the latter. To stand the best chance of fulfilling playthrough terms on slots, we suggest looking out for games that have a high RTP above the 96% average with low volatility for frequent expected payouts.”
Popular Games for Casino Bonuses
Every bonus can be used on different casino games, but at top UK casino sites, the rewards cover a wide range. While you’ll need to check the T&Cs to see which specific titles a promotion applies to, most bonuses are eligible for at least one of the following:
Slots
Online slots make up the bulk of games at many UK casinos, while also being beginner-friendly and generally having lower RTPs than table games. As a result, many gambling sites tend to regularly offer slots bonuses.
The most common type of bonus you can use on slots is free spins, although you can sometimes get other rewards to give yourself more money to play with before you hit the reels. Remember that certain slot games can be excluded from general offers, such as progressive jackpots.
Top 5 Slots for Free Spins Bonuses in July 2025
If you land a free spins bonus at an online casino and have a choice of slots to use it on, there are plenty of entertaining titles we recommend. Hit the reels on the following games the next time you have free spins at your disposal:
| Rank | Slot | Max. Win | RTP | Available at |
|---|---|---|---|---|
| 🥇 | Big Bass Splash | 5,000x | 96.71% | LeoVegas |
| 🥈 | Kong 3 Even Bigger Bonus | 10,000x | 95.00% | Neptune Play |
| 🥉 | Book of Dead | 5,000x | 96.21% | Duelz |
| #4 | Starburst | 500x | 96.09% | Dream Vegas |
| #5 | Double Bubble | 20,000x | 96.02% | 888 Casino |
Table Games
Table games at online casinos include blackjack, roulette and baccarat, and can be compatible with bonuses such as deposit matches and cashback. This gives you increased chances to beat the dealer or successfully bet on the roulette wheel.
The only downside is that table games tend to contribute less towards bonus wagering requirements than slots, as they often have higher RTPs.
Live Casino Games
Casinos sometimes run specific bonuses that you can claim for live dealer games. These give you additional funds to use on live table titles, such as live blackjack, live roulette and live baccarat. For instance, LeoVegas has a specific live casino welcome bonus for new players that matches your deposit up to £50.
Live Game Shows
Generally, you can also use live casino bonuses on live game shows. These are different to live versions of table games, as they are specific titles featuring a real host with original rules and gameplay. Entertaining live game shows at UK casinos include Crazy Time, Cash or Crash and MONOPOLY Live.
Bingo
With bingo becoming an increasingly popular game to play at online casinos, many gambling sites now offer bingo-focused bonuses. These can give you bonus funds that can be specifically used on bingo titles and free entries or tickets into live bingo games.
Instant Win Games
Bonuses for instant win games such as scratch cards and Slingo are less common, but are still available at some top UK casinos. The fast-paced nature of these games means that instant win bonuses more commonly tend to involve a specified number of free rounds, as opposed to specific bonus funds.
