Types of Casino Bonuses Explained
Casino bonus offers come in different shapes and sizes, including games bonuses and deposit free spins offers. so you can choose the one that fits your gaming style. Here is a guide to the most common new casino UK bonuses you’ll see:
Casino Welcome Bonus
A welcome bonus is awarded after you make your initial deposit. It’s the first reward you get when you sign up, and is great for exploring a site’s lobby without going all-in. Most UK welcome bonuses are made up of two components: a deposit match (where the casino matches a percentage of your first deposit as bonus credit, eg. 100% up to £50), and a free spins package on a selected slot. Some sites offer one or the other, while the most generous packages bundle both together.
Deposit Match Bonuses
This is where a casino matches what you deposit. So if you see “100% up to £100” that means you will get a casino bonus equal to whatever you deposit, up to a maximum of £100, usually paid as bonus credit (not cash).
Not every match bonus will be 100%, so always check the percentage, as well as the maximum amount. You also need to make sure you check the wagering requirements of your bonus credit, as well as how long you have before the bonus runs out. Only bonus funds count towards meeting these wagering requirements, and different games contribute differently. Slots usually count 100%, while table games often contribute less.
No Deposit Bonus
A no deposit bonus is typically a casino sign up offer for new players. The no deposit bonus usually gives you free spins to play with, before you’ve even made a deposit. A no deposit casino welcome bonus lets you play a game without risking a penny. However, these offers tend to be very small and usually come with higher wagering requirements. Additionally, many no-deposit bonuses have a maximum win limit, so any winnings above that limit will be forfeited upon withdrawal.
Free Spins Bonus
Despite the name, free spins are not always free. Often, to get free spins you will have to make a deposit. If you get free spins as part of the deal, you need to know whether you can only use them on certain slots, or if they have wagering requirements. Typically a free spins casino bonus will also be for specific slot games. Free spins are usually limited to eligible slot games, meaning only certain slot titles qualify for the bonus or promotional offer. Free spins bonuses allow players to play a slot machine for real money without wagering any of their own funds, and are often included as part of a welcome package or ongoing promotion.
Bonus Credit / Bonus Money
Bonus Credit is not quite the same as cash. You can place bets the same, but in order to cash out bonus credit you usually have to meet certain wagering requirements before you do. Sometimes, only bonus funds can be used for specific bets or games, and winnings from only bonus funds may be subject to particular conditions. Additionally, bonuses often have a cap on total winnings, such as £100 for no deposit deals, and a maximum stake allowed per spin, typically around £5.
No Wagering Bonus
A no wagering casino bonus does exactly what it says, i.e. any winnings you generate from your free spins or bonus credit are yours to keep. So, no playthrough conditions attached. They’re typically offered as wager-free free spins on selected slots, and winnings are paid directly as real cash.
Live Casino Promotions
Live casino promotions often feature live dealer tables, which simulate the experience of a land-based casino and bring an authentic atmosphere to online gaming. Live dealers are really the new way to play table games online, and live casino promos let you play these games with free chips on the house, or with surprise prizes thrown in. For example, there might be a card for a mystery prize added to the deck in a game of Blackjack, or every time the ball lands on 7 on a Roulette wheel, everyone gets an extra cash prize. Things can get pretty creative here.
Cashback Deals
A cashback bonus is when you’re offered a portion of your losses back, like the All British Casino welcome offer. Cashback casinos sometimes pay this amount in cash, sometimes in bonus credit. Some casinos offer daily, weekly, or monthly cashback promotions, often based on a percentage of your net losses during that period, like the Los Vegas 5% weekly offer. These offers can be especially appealing to regular players and VIP members, if you play often enough. It’s important to check the terms of cashback deals, as they may come with wagering requirements or limits on the maximum cashback amount you can receive. Additionally, some cashback offers require players to opt in to be eligible, so always read the fine print to make sure you don’t miss out on these valuable promotions.
Daily/Weekly Promotions
Online casino promotions often include daily, weekly, or monthly offers such as reloads, prize drops, tournaments, and occasional no-deposit perks. Many online casinos offer ongoing promotions in addition to welcome bonuses, which can provide additional value to players. You’ll also notice that during specific times of the year, daily or weekly promotions tend to increase both in value and frequency. Halloween and Christmas are good examples.
Referral Offers
Like where you play? Then bring a friend in and you’ll get an extra reward. Referral offers are a popular way for casinos to thank players who introduce new customers. Typically, you share a unique referral link or code with your friends, and when they sign up and meet certain conditions (such as making a deposit or placing a bet) you receive a bonus. These rewards can come in various forms, including bonus money, free spins, or even cashback.
Loyalty Points / VIP Club
Sort of like air miles. You collect points for every bet you make, and with enough points you can move up levels, unlock extra prizes, and even get exclusive invitations to tournaments. A VIP reward programme is more niche, usually reserved for people who wager a lot. If you like loyalty programmes or VIP clubs, we recommend you also ensure you use safer gambling tools, like deposit limits.
How to Choose the Best Casino Bonuses
To find the best casino bonuses UK players should consider the following key factors:
- Wagering Requirements (ideally none)
- Reasonable expiry dates
- Good casino bonus credit amounts
- Fair game contribution
- No hidden “max withdrawal” rules
- Clear info on how to withdraw bonus winnings
- Instructions on how to claim free spins as part of the sign-up bonus, and the importance of reading the terms and conditions to understand any restrictions or requirements
- Always check for game restrictions, as some bonuses can only be used on certain games or may exclude specific titles from eligibility.
What is a Wagering Requirement?
A wagering requirement (aka a playthrough requirement) is the amount you have to bet in real money before you can withdraw any winnings you had while playing with a bonus.
It is found in the promotion’s terms and conditions and is perhaps the most important part of any bonus as they define how good the deal really is. Yet it is also one of most poorly understood concepts, so here’s a straightforward explanation with some examples.
You deposited £100 and claimed a 50% bonus, receiving £50 in bonus money. The offer has a wagering requirement of 10x. Multiply your bonus of £50 by 10, and you get £500. £500 is how much you need to wager in real money bets before you can withdraw your win.
You deposited £100 and claimed a 50% bonus, receiving £50 in bonus money. The offer has a wagering requirement of 5x the bonus plus deposit. Your bonus is £50 and your deposit is £100. So what you do is (50+100) multiplied by 5. That’s 150 x 5, which gives you £750. £750 is how much you need to wager in real money bets before you can withdraw your win. Watch out for the “bonus plus deposit” term, because although it looks lower at first, you can see that it ends up being more expensive after you do the maths.
Since 19 January 2026, UK-licensed operators have been limited to a maximum of 10x. This makes welcome offers a lot more straightforward. For example, a £10 bonus that previously needed £650 of play-through at 65x would drop to £100 at 10x.
The best casino bonuses typically have lower wagering requirements, making it easier to cash out. Avoid bonuses with high requirements, as they can be harder to turn into real money.
It’s also worth playing your bonus at a casino with a strong overall payout rate, as this affects how far your bonus funds stretch. A higher site-wide payout percentage means more of your wagered money comes back to you while you clear those requirements. See our guide to the best payout casinos for sites that consistently return the most to players.
Bonus Types
As we’ve outlined in the previous section, there are various types of bonuses: welcome bonuses, no-deposit bonuses, and free spins, among others. Many of these bonuses are specifically designed for casino slots, which are among the most popular games for bonus play. If you’re a new player, a generous welcome bonus could offer a great way to start. If you prefer casino slots, free spins might be more beneficial, letting you try out a variety of modern, multimedia-rich slot games with exciting themes and bonus features. Or you may prefer a bigger match bonus and be able to choose the games you play. Identify which bonus type fits your playing style to make the most of the offer. Even if you can’t convert to withdrawable winnings, you want to have fun trying.
Maximum Bonus Amount
Look at the maximum bonus amount you can claim. Some offers provide smaller rewards, while others can significantly boost your bankroll. However, be aware that many bonuses come with a max bonus conversion limit. This means there is a cap on how much of your bonus funds can be converted into real cash after meeting the wagering requirements. Ensure that the best casino bonus for you at least offers a decent match to your deposit, but also check if the bonus is worth pursuing based on your typical betting limits.
Eligible or Specified Games
Always check which games are eligible for the bonus. Some bonuses might be restricted to certain slots, table games, or even slingo games (Slingo is a hybrid of slots and bingo where you draw numbers, form lines, and enjoy bonus rounds). Slingo games may have specific eligibility rules, so if your favourite game is excluded, the bonus might not be worth it for you.
By considering all these factors, you’ll be better equipped to choose the best casino bonuses UK that suit your gaming preferences.
How to Claim Your Casino Bonus
To claim the best casino bonuses you will usually need to meet a few criteria set out in the terms and conditions.
However only 60% of players read the T&Cs before claiming an offer, and 78% of people don’t find T&Cs easy to understand (according to WhichBingo’s UK Bingo & Casino Player Survey).
We are here to ensure you don’t miss out on any casino sign up offers due to technicalities or misunderstandings.
- Choose the Right Casino – First, identify an online casino that offers the most appealing casino bonus to you (with our help, of course, as we search out the best weekly casino bonuses to display on WhichBingo). Check the bonus type (welcome bonus, free spins, no deposit bonus), and ensure it fits your playing style. Consider whether the casino is a mobile casino or offers strong mobile compatibility, which is important if you want to play on the go. Always read the terms and conditions to verify wagering requirements and eligibility.
- Sign Up for an Account – Once you’ve selected the casino, create your account. This typically involves providing your name, email, and personal details – most of our casino brand reviews have a comprehensive section on registration. Make sure to use accurate information, as many casinos require identity verification before processing withdrawals.
- Opt-In for the Bonus – Many casinos require you to opt-in for the bonus offer, either during registration or before your first deposit. Make sure you check the relevant box or enter a bonus code, if applicable. If you miss this step, you may not receive the bonus.
- Make Your First Deposit – To claim the best casino bonuses, you’ll often need to make a qualifying deposit. Ensure that your deposit meets the minimum amount required for the bonus to trigger. The usual amounts are £10 or £20, but a handful of sites let you get started for less. If you’re looking to keep your spend low while still claiming a reward, check out our dedicated guide to £5 deposit casinos. Some casinos may offer higher bonuses for larger deposits, so choose an amount that fits your budget. When selecting a payment method, debit cards are a secure and widely accepted option. But watch out for deposit methods that might be excluded from the bonus deal – often PayPal, Neteller or Skrill might not be eligible.
- Meet the Wagering Requirements – Before withdrawing any bonus winnings, you’ll need to meet the casino’s wagering requirements. This means playing through your bonus a certain number of times. Be aware that bonus funds expire after a set period—typically within 7 to 30 days—and if you do not meet the wagering requirements within this timeframe, both the bonus and any winnings will be forfeited. Be sure to understand these terms to avoid any surprises when trying to cash out.
By following these steps, you can confidently claim the best casino bonuses and make the most out of your gaming experience. We do the hard work by seeking out partners with the best casino bonus UK offers for new players.
Casino Bonus Limits
Casino bonuses also come with some other limits that it’s important to be aware of.
Time Limits
Most Welcome Bonuses are valid for between 7-30 days. In practice, this means you have 30 days after you have made your first deposit and claimed the bonus to meet the wagering requirement. Once the time is up, any unused bonus sum is removed from your account, and can no longer be played with or cashed out.
When you receive bonus spins as part of a sign-up deal or promotion, these will only be available for a limited period of time, usually no more than 7 days. Free spins expire after a set period, typically ranging from 24 hours to several days after being credited, so be sure to use them before they become invalid.
Game Limits/Game Weighting
Game weighting means not all games contribute equally to wagering requirements. For example, slots usually count 100%, while table games like blackjack or roulette may contribute only 10%–20% or be excluded entirely.
At some sites there will be restrictions as to what games you can play with casino bonus funds. It will also be the case that some games, such as scratch cards, some table games and live dealer games, make no contribution to clearing the bonus.
In bonuses where you are awarded bonus spins, these will usually be on a nominated game and have a fixed value (likely to be around £0.10 per spin).
It’s important to note that wagering contributions vary by game. Some games, like slots, often contribute 100% towards wagering, while table games, scratch cards, and video poker may contribute much less or even nothing. Always check which games count most towards clearing the bonus to maximise your chances of meeting the requirements.
Win limits
Most casino Welcome Bonuses also have a maximum conversion amount, which is the maximum amount of bonus winnings that can be transferred to your real money account and cashed out.
This is often referred to as the win cap or win limit, and it caps the amount you can withdraw from your bonus-related earnings, including winnings from free spins or bonus funds.
It will vary, but the limit is often tied to your lifetime deposits, so if you’ve deposited £50 during your time at a site that is the max you can win.
Wager Limits
With most bonuses that have a wagering requirement, there will be a maximum bet size. In the UK this will be £5 per spin on slots, but it can vary so make sure you check the T&Cs.
If free spins are not used within the allotted time, they become dead bonus spins and cannot be used to win or withdraw winnings. Prioritizing no-wager bonuses allows players to receive winnings as cash immediately, without any playthrough requirements.
Responsible Gambling
The best casino welcome bonus is one that enhances your entertainment, not your stress.
Responsible gambling is at the heart of a safe and enjoyable online gaming experience and we take it extremely seriously at WhichBingo.
We recommend using responsible gambling tools to your advantage to help you play smarter:
- Deposit limits – Treat them like a budget
- Reality checks and session reminders – Keep track of your time and spending
- Take a break – It’s ok to step away from gambling
Remember, when you sign up for a casino welcome offer or claim a casino bonus, it should be for fun and never feel like a necessity. Play smart, set your limits, and make the most of your online casino experience.
Check out our Responsible Gambling page or the UK Gambling Commission for hints and tips on how to play and have it remain a pleasure and not a problem.

Beware of Black-market Casino Bonuses
The UK has seen a rise in non-gamstop casino sites which sit outside UK regulations. Nongamstop sites offer big casino bonuses up to £1000 but these often come with 40x wagering requirements (when the UK legal maximum is 10x).
So you’d need to wager £40,000 before any bonus winnings can be withdrawn!
WhichBingo’s 2026 Player Survey of 1,915 UK players found that 14% of people had been tempted by a black-market casino site – but our advice is to not get tempted by the big numbers.
A bigger casino welcome bonus number on a non-GamStop site means a harder bonus to cash out. So always read the wagering requirement and maximum win in the terms and conditions, and check the casino is UK licenced or you will have no recourse if you get ripped off.
Every casino bonus on WhichBingo comes from a fully licensed site that has fair terms and conditions dictated by the UK Gambling Commission.

Casino Bonuses FAQs
What is a casino bonus?
A casino bonus is an incentive that a casino offers you (often free spins or bonus credit) if you make a deposit. A casino bonus could be part of a welcome offer, or it could be a regular promotion.

It depends what you want, the best casino bonus for no wagering requirements is PlayOJO’s 80 Wager Free Spins.
No wagering casino bonus are best because if you win anything it will be paid as cash.

What is a casino welcome bonus?
A casino welcome bonus (aka a sign up bonus) is the first offer when you first join and make a deposit.
It can take different forms, but this sort of bonus will usually give you a match on your first deposit
A sign up bonus might also give you bonus spins on selected slot games.
Can I keep the money on my bonus?
In order to be able to withdraw any of the bonus amount you are awarded, you will usually have to fulfil wagering requirements. This is a set amount that you are required to wager (usually on slots, but not exclusively) before you are able to transfer any bonus sum to your real money account. There are some exceptions to this rule where you don’t have to meet a wagering requirement, but they are fairly rare.
Is it easy to withdraw bonus winnings?
Once you have met the wagering requirements, any bonus money will usually be transferred to your real money account; from here, simply follow the site’s instructions for cashing out.
However, it is important to note that some sites have a maximum conversion amount, which is a limit on how much of your bonus account can be transferred to your real money account, effectively limiting how much of the bonus you can withdraw.
Do casinos bonuses expire?
Welcome bonuses are usually valid for 7- 30 days (although the time will vary from site to site), which is the amount of time you have to meet the wagering requirements.
If you haven’t managed to do so in the time required, any unplayed bonus will be forfeited, and you will not be able to cash out any of the bonus amount.
How do wagering requirements work?
A wagering requirement (aka a playthrough requirement) is the amount of times you have to bet before you can convert a bonus into cash.
So a 10x wagering requirement on a £10 bonus means you have to wager £10 ten times (total £100 in wagering). You could place 100 bets of £1 if you wanted or 50 bets of £2, as long as you meet the total.
