Barz Casino - 100% up to £300 + 50 free spins
Barz comes flying out of the gates with a superb offer. This consists of a 100% matched deposit of up to £300 which is extremely competitive. If that isn’t enough, you will also have 50 free spins thrown into the mix to be used on Starburst.
Ok, the wagering requirements are fairly high (40x), and you must use the deal within 72 hours or risk forfeiting it. However, we didn’t have many qualms with the minimum deposit set at £20, and Barz has one of the most generous free sign up bonus offers in the industry.
Playzee - 100% up to £300 + 100 Zee Spins + 500 Zee Points
Like Barz, Playzee has a brilliant welcome offer that entails a 100% matched deposit of up to £300.
But that’s not all. Playzee wants to enrol players into their bespoke loyalty program where they can pick up points based on how often they play. There is a daily deal, so for example, on a Friday, for every £200 cash wager on a game, Playzee will boost your account with a £5 bonus of up to £10.
This sign-up bonus serves a dual purpose and we think it keeps players interested the moment they register.
Grand Ivy - 100% up to £300 + 25 free spins
This may fall just short of Barz Casino’s incredible offer, but don’t moan about the sign up bonus casino offer at Grand Ivy. A 100% matched deposit of up to £300 and 25 free spins on Starburst packs a punch.
Grand Ivy has a few ways to make deposits to collect this deal, including debit cards and trusted e-wallets, such as Skrill and Neteller. After careful research, there didn’t seem to be any stipulations about exempt deposit methods to collect the bonus, therefore giving players more freedom.
Casushi - 20 Free Spins with no wagering requirements
A free casino bonus is always warmly appreciated, and Casushi hits the mark here.
Ok, so you do need to deposit a minimum of £10 to qualify for this offer, however, the good news is that you can latch onto 20 free spins on Big Bass Splash with no wagering requirements.
Winnings will be wired directly to your cash balance, and we think it enhances the fun. Spin the reels and see what all the fuss is about with this slot.
Peachy Games - 100% up to £50 and 20 Free Spins
Low deposit casinos are celebrated, and the ones where you need a minimum deposit of £10 are worth looking at more closely.
Our research brought to our attention some of the best first deposit bonus casino UK sites, such as Peachy Games, whereby new players can claim a solid 100% bonus of up to £50 along with 20 free spins to be used on Big Bass Splash.
Wagering on specific games might only contribute 10% towards the deal, while the wagering requirements are relatively middle of the road at 35x. Casino bonus UK operators such as Peachy Games are worth your time!
What are Casino Bonuses?
Shiny and eye-catching, a casino bonus will be the first thing you are likely to encounter on the homepage when you visit a reputable site. But what are they?
Casino offers will be well sign-posted and they are designed to reward players for joining an operator. They can also be used to keep existing gamblers on their side through a mix of loyalty programs and other free bet offers. The loyalty programs, as you will discover, may be more suited for high rollers or those with a more flexible budget.
A good welcome deal can grab the attention of players by convincing them to spend more time at a site in search of cash wins. At some operators, players might be given a referral bonus for encouraging friends or family to sign up for a casino brand, so you can benefit from doing your bit and spreading the word about a site.
However, with bonuses, there will be a set of strict terms and conditions that need to be met so you can kickstart your casino journey in the best possible way. We have briefly listed some of the most common T&Cs attached to a deal. Don’t worry, these will be more discussed later on in the guide:
- Wagering requirements
- Bonus eligibility
- Accepted payment methods
- Expiry period
- Games contribution (% attributed to slots, table games, and live casino games)
- Age restriction (linked to bonus eligibility)
- Promo code
Types of Casino Bonuses
No casino bonuses are identical. They will be unique, and they can set the tone for a gambler’s experience. We have examined some of the most popular and sought-after casino promotions in this section.
Welcome Bonuses
Also known as a casino sign up bonus, the welcome bonus is supposed to sparkle and highlight why a player should join the site. The most common welcome deal is a matched deposit bonus, whereby players will have extra funds depending on how much they deposit.
The percentage usually ranges from 50% to 100%. So, if the offer advertised is a 100% matched deposit of up to £200, if you max out the deposit, you will have an extra £200 to play with. What’s there not to like about that? In many cases, players will have 30 days to take advantage of the promo and they will need to meet any wagering requirements expected.
Some of the best casino sign up offers may also dangle the carrot of extra free spins which will go down with a treat for slot fans. Claiming a deal is straightforward, and can be done as such:
Step 1 - Pick a casino and fill in all the required fields of the registration form.
Step 2 - Verify your details and head over to the banking section to pick from the available deposit options.
Step 3 - Make your first deposit and claim the bonus. There may be a promo code to enter too.
Step 4 - Play your favourite games as part of the T&Cs. Good luck!
Best Casino for Welcome Bonuses
Barz Casino is our pick for welcome bonuses. Aside from a healthy matched deposit bonus (100% up to £300), 50 bonus spins are thrown in, combining the best of both, and it is worth tapping into.spins. With a high bonus percentage and generous free spins, this offer maximizes your bankroll from the start.
No Deposit Bonuses
No deposit bonuses are what we consider to be the holy grail of casino offers. They will be given to players simply for signing up for a site, and there will be no strings attached. Sounds too good to be true, right?
Honestly, they do exist and they are highly attractive as you won’t need to make a qualifying payment. A free sign up bonus will chime with novice bettors who are looking to dip their toes in at a site, but may be more reserved when it comes to spending serious sums of money.
These can entail free spins with no wagering requirements, free spins upon registration, or even free spins for existing players.
Among the typical T&Cs tagged onto no deposit free spin deals include:
- Free spins will be awarded to a player once they have signed up for the promotion.
- The free spins will expire if not used within 7 days of collecting the promo.
- Free spins will be available for selected games.
- Offer is subject to casino terms and conditions.
Best Casino for No Deposit Bonuses
Casushi - Even though it isn’t strictly a no deposit deal, Casushi gets the nod from us as there are no wagering requirements for the 20 free spins available.
Free Spins
Free spins are as they sound. You can use these to play your preferred slots, and these can either be standalone deals or connected to a matched deposit.
Among the best £10 deposit bonus UK sites that offer free spins, include Casushi, where the current deal entails 20 bonus spins on the iconic slot Big Bass Splash. There are no wagering requirements, but the bonus will expire within 48 hours of making a deposit.
At other sites, where a bigger deposit is required, such as at Grand Ivy (£20), the bonus which includes 25 free spins on Starburst, is subject to relatively steep 35x wagering requirements, and bonus funds are capped at £100.
Best Casino for Free Spins
In our opinion, Jackpot Village has the best free spins package, and 200 free spins to be used on Book of Dead is almost unheard of!
Cashback Bonuses
We think cashback bonuses are a treat as players will recover losses accrued at their chosen casino over a week. The beauty of this is that players will have a safety net if things don’t go according to plan while gambling.
Compared to traditional welcome deposit offers, the cashback bonus can be a motivating factor for players. For example, a casino could offer a 10% daily or weekly refund on lost deposits. So, if you deposited £60 on slots and lost it all, then you would get £6 at the end of a week which is better than nothing.
Best Casino for Cashback Bonuses
All British Casino prides itself on always offering cashback (10%) alongside its welcome bonus which we think makes the deal extra sweet.
Loyalty Programs & VIP Bonuses
Loyalty bonuses are given to players who show their commitment to a casino for continued play. The programs that are run will be split into tiers or levels, and the higher players climb, the bigger the rewards.
For high rollers, there will be exclusive deals and they will be the first to hear of them. Among the benefits you can expect to find, include birthday gifts, withdrawal priority, and access to a VIP host who will guide you through your casino journey.
These perks won’t go unnoticed and you can tap into these by collecting points. Playing certain games may earn more points than others, but casinos will roll out the red carpet to those that put the hard yards in.
Best Casino for VIP & Loyalty Bonuses
Playzee Casino has its finger on the pulse for loyalty bonuses. By joining the program you start earning zee points, which can be converted into bonus funds. With varying rewards, every day will bring fresh surprises, so get involved!
Special Events & Seasonal Bonuses
Casinos that want to make their mark throughout the year will have dates noted in the calendar with special themed bonuses to entice players.
This might include Easter and Christmas, and even special dates such as Valentine’s Day. We noticed 10bet was running a 25% matched deposit bonus of up to £100 for Valentine’s Day, and players will have to meet the 40x wagering requirements which is high but not unobtainable.
These bonuses which might entail free spins or matched deposits add an extra layer of excitement to things, and players may well appreciate a casino going the extra mile.
Best Casino for Seasonal Bonuses
10bet relishes a seasonal bonus, and the 25% matched deposit bonus up to £100 which was available for Valentine’s Day is an enticing proposition.
How to Choose the Best Casino Bonus
Pinpointing the best casino offers means doing your research, so you find the right deal that suits you. We have discussed the factors you should take into consideration.
Payment Methods and Bonus Eligibility
UK casinos can be quite strict about the types of payments accepted. Usually, there will be no problems with collecting casino sign up offers using a debit card, such as VISA, but certain banking methods may be exempt.
This might include e-wallets, such as Skrill and Neteller. Meanwhile, check to see if you meet other eligibility requirements such as age (18 or above), and that only one member per household is collecting the offer.
Wagering Requirements
Wagering requirements are a critical component of the T&Cs. They represent a multiplier of how many times you need to play through a bonus before you can pick up winnings.
So, a £50 casino bonus with 20x wagering requirements means you need to spend at least £1,000 on eligible games before receiving winnings from a casino. They tend to vary from one site to the next, but ideally target sites with lower wagering requirements (20x or less).
Game Contributions
There may be certain casino games that will be included or banned from a particular offer. Terms will be transparent, but often, slots may contribute the full 100% to an offer.
You might see a sliding scale of games that might contribute to the bonus, with slots at the top, while some table and live casinos might contribute a minimal amount. Some games, such as craps might be excluded. This is partially to do with its fast-paced nature as well as the house edge whereby casinos might keep more winnings.
Bonus Validity Periods
This refers to how long you will have to make use of your bonus before it expires. Bonus validity periods will vary from one casino to another.
Grand Ivy allows players 30 days to make use of the bonus before the funds expire, but this should be ample time. In some cases, bonuses might be available for seven days or less, so always read the small print.
How to Claim a Casino Bonus
Collecting a welcome promo ought not to be too tricky. We have shown you how to reap the benefits by using a simple step-by-step guide:
Step 1: Choose a Casino
Spend time browsing through online casinos, exploring the merits of each before signing up for one that matches your expectations. Going through reviews and checking the validity of each operator is a crucial part of the process. The most reputable will have great bonus casino deals to tap into.
Step 2: Sign Up & Deposit
Head to the top right-hand corner of the site you wish to join and click the “Join Now” button. You will be asked to fill in and confirm a series of details as part of the registration process, such as name and email address, so make sure they are correct. <br></br> Also, you will notice the conditions attached to the bonus, so check these out before proceeding.
Step 3: Claim & Play
After confirming your details and picking from the approved list of banking options, claim the welcome bonus and enter a promo code if applicable. Make sure you can meet the T&Cs, such as wagering requirements to get the most from your time spent at the casino. If you are, then play your favourite games now.
Conclusion - Making the Most of Casino Bonuses
In summary, no casino sign up bonus offers are the same, and all must be judged on their own merits.
Matched deposit deals are perhaps the most common, and Barz Casino has arguably one of the most generous deals out there. A 100% matched deposit of up to £300 and 50 free spins is a sizzling deal, but remember, it takes time to translate casino play into winnings.
All T&Cs need to be read with a fine tooth comb as missing the small print can lead to disappointment down the line. Barz may have the best deal for new players, but rival sites have upped their game and they also appeal to existing customers with ongoing deals.
Whatever your preference of casino site, don’t take anything for granted. If you have followed the advice and tips we have suggested in this guide, then you won’t go too far wrong. The main takeaway is to read the T&Cs and always gamble responsibly.
