Best Casino Bonus Sites UK 2025

Bonus spins will be credited at a rate of 20 bonus spins per day over five days, triggered on your first deposit

This Hello Casino bonus gets our “Recommended” rating, mainly due to the low max cashout of only £50. This value limits the potential winnings if you decide to deposit amounts close to the maximum £100. Overall, it is still a compelling offer for slot fans who enjoy using their free spins on Gonzo’s Quest or Starburst. The wager is 35x, which is fairly standard and achievable by most players.’

To claim the bonus, you have to submit the code “FIRST20” on the first deposit.

‘

We rate the PlayMillion bonus as Poor. You can claim a 100% match up to £20 with a reasonable £10 minimum deposit. However, the attached wagering requirement of 60x is extremely high. This difficult rollover makes actually cashing out bonus winnings highly unlikely for the average player.

• You can use the bonus spins on Starburst by NetEnt.
• The spins will be credited in batches.
• The bonus must be wagered within 21 days of receipt.

By depositing £20, you can claim this first deposit offer from PlayFrank Casino, which is a great opportunity to double your funds and receive extra deposit spins. You can get up to £100 that can be wagered on any PlayFrank Casino slot, which is an opportunity to widen your gambling experience. The 50 bonus spins are limited to the game Starburst by NetEnt, one of the provider’s most-known games. You can cash out a maximum of £100 from the spins, which is a great amount for new players joining the casino.

The bonus spins expire within 24 hours.

We give Dream Jackpot’s 50 Big Bass Bonanza spins a recommended rating. New players depositing over £20 receive risk-free rounds on a popular title. With a £100 maximum withdrawal cap, this provides solid gameplay value. Our main critique would be the 35x wagering requirement if you do hit a big win, which may prove difficult to clear within time limitations. But for the upfront free spins accessible with an average first deposit, it’s a nice incentive to try Dream Jackpot’s offerings.

New players at Conquer Casino can claim a 200% match bonus up to £50 plus 15 Free Spins on the Book of Dead slot, but the rules are rather harsh. The deposit match bonus expires after 30 days while free spins expire after 7 days if unused. The welcome bonus has a 50x wagering requirement on just the bonus amount. Winnings are capped at 3 times the bonus amount.’

Skrill and Neteller deposits will not grant you this bonus.

We give this bonus offer from Conquer Casino a “Poor” rating due to the overly restrictive playthrough rules. The match percentage of 100% will double your available funds, but the 50x rollover needed before withdrawal is hard to overcome. The 10 free spins on Starburst are not enough to make up for this disadvantage because the wins are capped at just £20.

The first batch of free spins will be credited after the initial deposit. For the other two sets of spins, you have to log in for two days.

We rate the Spin Rio bonus as Recommended. You can claim a generous 150% match up to £40 on your first deposit. This adds extra funds to play with on top of your initial deposit. You will also get 75 free spins, split over three popular slot games. With a £10 minimum deposit, the offer is accessible. The attached 35x wagering requirement is fairly average. Overall, the sizeable deposit match and number of free spins make this welcome bonus worthwhile.

• To claim this bonus, use code MAGIC50 when making your first deposit.
• The deposit spins are credited for the game Book of Dead by Play’n Go.

This first deposit bonus from Slots Magic Casino is a great opportunity to try the popular Book of Dead slot by Play’n Go using 50 bonus spins. However, the spins require a high wagering, which makes this bonus more suitable for high rollers. By depositing at least £10, you can double your funds to up to £50, which can be used on any available slot at Slots Magic Casino. This bonus offers players the chance to explore the casino library in search of a new favorite slot using bonus funds while spending the free spins on one of the most popular games in the industry.

The 100% welcome bonus from Magical Vegas Casino doubles your standard £10 first deposit to up to £300. It also comes with 30 deposit spins with no game limitations, making us rate it as recommended. You should know that the spins and the match bonus are subject to higher-than-average 50x wagering requirements. You can cash out up to 5x the bonus amount from this Magical Vegas Casino first deposit bonus, while the bonus spins have a 5x winnings cashout cap.

• The spins can be used only on Starburst by NetEnt.
• You will receive the spins in daily batches, each available 24 hours.

This Simba Slots Casino free spins on deposit bonus offers you the chance to play the popular NetEnt slot Starburst with bonus spins by making a standard £10 deposit. The winnings from the bonus spins are subject to a 65x wagering, which is considerably higher than the industry standard of 35x, making this bonus less accessible for new players. However, you can cash out up to £250 from this offer, which is a great amount for a free spins on deposit bonus.

• You must use our exclusive link and access the casino Promotion page to claim this offer.
• This welcome offer includes a free spin on the Mega Reel after making your first deposit. Prizes may include up to 500 free spins on Starburst or Amazon vouchers.
• The maximum bonus conversion for accounts with deposits is equal to your lifetime deposits, up to £250. For non-deposit accounts, the maximum conversion is £50.
• Prizes on the Mega Reel are determined by chance, and winnings are not guaranteed.

Slots Animal’s Mega Reel welcome offer stands out with the chance to win up to 500 free spins on Starburst or other interesting prizes. The offer’s flexibility and unique prizes add appeal, but the 65x wagering requirement on winnings and the maximum conversion limits (£250 for depositors, £50 for non-depositors) significantly reduce the bonus’s overall value.

• Use our exlusive link and check the Promotions page of the casino.
• Make your first minimum deposit to receive a free spin on the Mega Reel, where you can win up to 500 Free Spins on Fluffy Favourites or other prizes.
• The Mega Reel prizes are not guaranteed as it operates as a game of chance.
• The free spins are valid for 7 days after being credited.

The Lights Camera Bingo Mega Reel welcome offers provides an exciting way for new players to start gaming with a chance to win up to 500 Free Spins or Amazon vouchers. However, the 65x wagering requirement is high, and the £250 max bonus conversion cap limits the overall cashout potential. Furthermore, the fact that the free spins are not guaranteed might discourage some players.

• New players get a free spin of “Lucky Star” on their first deposit.
• Free Spins can only be used on games specified by the casino. Specifically, they can be used on the popular and highly regarded slot provided by NetEnt.

The 500 Free Spins offer on Starburst at Space Wins is great if you’re a new player, giving you the chance to try a popular game with the potential to win. However, the wagering requirements and limits on the conversion of winnings may reduce the chances of withdrawing large amounts. It’s a good offer for those who want to have fun and discover new games, but be aware of the restrictions.

This Fever Bingo Casino bonus requires a minimum of £20 to qualify for winning up to 500 spins, though you must be aware that the more you deposit, the higher the chance of redeeming a bigger batch of free spins. The rollover requirement is 65 times the bonus amount, which is quite high compared to the market average of 35x when it comes to free spins on deposit. Overall, our team rates this bonus as Recommended since you still get a reasonable number of free spins.’

This Fever Slots Casino bonus offers players a 100% match on the first deposit of a minimum of £10, doubling the deposit. Players can get up to £200 in bonus funds, with a 65x wagering requirement. The wagering is considerably higher than the industry standard of 35x, making the bonus suitable for experienced players. The bonus allows players to cash out up to £200 from this promotion. 

• By receiving the highest number of 500 extra spins, 50 are instantly attributed to you, while for the rest, you should contact support;
• You will spin the Mega Reel Wheel that indicates what you win.

We rate this bonus as Poor. Zeus Bingo offers new players a spin of the Mega Wheel, which awards prizes like Amazon vouchers or up to 500 free spins upon first deposit. The welcome bonus carries a high 65x wagering requirement. Only lifetime deposits up to £250 can convert to withdrawable funds. Though the wheel spin prizes seem enticing, the restrictive bonus terms prevent meaningful conversion to cash.’

• To claim this bonus, you must validate your card
• The number of spins you get is decided by the bonus wheel you spin after you claim the bonus

Our team of experts consider that this Aladdin Slots casino bonus should be rated as recommended since you get an extremely large number of spins. However, we aren’t fond of the wagering requirement, which is 65x, higher than average, as well as the maximum cashout value of £250, which we see as low for the number of spins you get.

• The maximum conversion is equal to the player’s lifetime deposits at the casino.

This UK casino bonus receives a low rating due to its restrictive terms. While the offer of a match deposit up to £2000 may seem generous, especially with the 1000% deal, the bonus has a significant drawback: the maximum cashout amount is limited to the player’s lifetime deposits. This means that new players cannot win more than they have already invested. Additionally, the wagering requirement is set at 65x, which is significantly higher than the industry average.

You must complete the KYC verification to be eligible to claim these spins.

We consider this Jackpot Village bonus to be recommended due to the high value of 200 spins on one of the most popular games of the industry, Book of Dead. The offer activates when depositing over £20, which is a higher than average value, but the 72 hours expiration is higher than usual. Meanwhile, the £20 maximum conversion from winnings seems fair for a free spin offer.

This Kwiff Casino was deemed as Recommended by our team of gamers, though keep in mind that the bonus requires punters’ special attention. In order to receive the 40 free spins, you will have to deposit and play with £20, which is a rarer requirement. Moreover, though limited to a single game, the free spins are viable for the Book of Dead slot, which is a very popular game on the UK market. Were the deposit requirement a bit lower, then our mark would have been Very Recommended.

• For this offer enter the bonus code: FREEDEPOSIT.
• The bonus and winnings expire in 30 days if unused or if wagering requirements are not met.

Fruity King Casino welcome bonus gives bonus money and free spins on Reactoonz slot after your first deposit. But, you have to bet 50 times the bonus amount to get real cash, which may be hard to meet. You must use the bonus in 30 days, or it goes away. Winnings can only be three times the bonus amount. Free spins don’t need to be bet to get winnings, but you can only win up to £20. It’s fun to start, but the high betting requirements and low win limits are not great.

• The bonus can only be claimed by following our link.
• Make sure to finish registering and submit all necessary documents.
• You cannot make deposits using Skrill or Neteller.
• The spins are valid for the Big Bass Bonanza slot game.

FruityKing Casino’s welcome offer doubles your first deposit up to £100 and throws in 50 free spins, but the 35x wagering requirement applies to the bonus amount. You have 30 days to use the bonus and 7 days for the spins, but keep in mind that the bonus itself isn’t withdrawable, only the winnings from it.

• This bonus is part of a welcome package which consists in 3 different deposits
• The bonus value will be determined by spinning the bonus wheel

Our team of experts recommend claiming the Star Wins casino welcome package as it will award you with a bonus wheel spin which can give you a value of up to £2000, which is extremely high for a first deposit bonus. Meanwhile, the 65x wagering is high and £250 max cashout is low, making these values under other competitors. We consider this bonus to be a great fit for you if you are a more experienced player which knows how to take advantage of the maximum cashout limit.

CasinoAlpha experts have rated this Mirror Bingo Casino offer as Recommended. The minimum deposit of £10 is average, though there is no guarantee you’ll win the full bonus amount of 500 free spins just by depositing this sum. In short, the more you deposit the more chances you have of hitting the limit of 500 spins, which is what made our team rate the bonus lower than usual. The wagering requirement of 65x did not aid in our review, since it is higher than the market standard.

NewSpins Casino’s welcome offer was reviewed by our experts, who gave the promotion a Poor rating due to restrictive terms diminishing its potential value. The 65x wagering demand is remarkably high and withdrawal capping is tied to deposit history. With limits of £250 in withdrawals and caps equal to lifetime deposits, this bonus misleads with its large spinning headline. Email-only customer service also hampers the player experience. While the Reel spin contains rewarding prizes, the extensive limitations make actually benefiting unlikely. Considering the maximum cashout barriers, experts urge players to deposit only sums they are comfortable forfeiting. We advise NewSpins to ease wagering rules and caps so this offer matches its advertised excitement.

The bonus type and value depend on your prize in the Loot Chest.

This Wild West Wins bonus has various terms that can change the overall value for the players, and our bonus testing team doesn’t recommend claiming it. The maximum prize of 500 free spins on various slots is not guaranteed. Moreover, there’s no guarantee that you’ll win any prize, a rule also specified in the bonus terms. The 65x wagering condition on any winnings is way higher than the average, which means you have smaller chances to get real value out of any prize. The £10 minimum deposit is significant but comes with a downside: your withdrawal limit is set to an amount equal to your lifetime deposits, so if you start with just £10, that’s the maximum you can convert to real money no matter what your bonus is.

• Access this offer through our link.
• Submit all necessary information and documents for registration.

Wild West Wins offers a huge 100% match bonus up to £2,000 on your first deposit, but the 65x wagering requirement makes cashing out a challenge. Plus, your max withdrawal is capped at your total lifetime deposits, up to £250, which limits the real value of this offer.

You will get the free spins randomly, as this bonus will give you a bonus wheel to spin, which can give you up to 500 spins.

Our team of experts recommend this Free Spins Bingo casino bonus as the spins number of 500 is extremely large. However, we don’t appreciate the fact that the wagering requirements are high, at 65x and the maximum cashout is low, at £250.

• Players will have to contact support to redeem this bonus
• A £10 minimum deposit will not grant the whole bonus amount

This OK Bingo bonus sounds good, but once our team read the terms and conditions, we noticed that the minimum bonus of £10 does not guarantee a bonus value of £2000, meaning that the more you deposit, the closer you’ll be to redeeming the actual bonus amount. In the end, the required amount may prove too high for beginners, and so may the wagering requirement of 65x. In this situation, the minimum bonus value is deceiving, and thus we will not recommend it to our new punters.

• 5 spins on sign-up for Immortal Romance
• You receive a try to the Loot Chest to claim up to 500 extra spins on Immortal Romance and the chance to win some prizes like Amazon vouchers.
• The ‘Loot Chest’ will only be credited on your first deposit on the site
• Only bonus wagers will contribute towards fulfilling the wagering requirements

Pros: several games from top-brand producers, loyalty program available, swift payouts
