— 100% up to £50 on your first
— 50% of up to £75 on your second
— and 50% up to £75 again on your third

You don’t need to use all three of these, but why not, right?

For sure, it would’ve been nicer to have a 100% bonus on each of the three deposits, but there’s no obligation to take up the 50% ones if you don’t want to.

This is a pretty neat set of welcome bonuses overall.

3. Spend £10, Get 40 Spins [mrQ]

We love the simplicity of the Grosvenor welcome bonus. Simply put down a £20 casino deposit, and you’ll get it matched by 100%. Plus, you’ll be able to get an extra £10.

Technically, this is an up to 150% matched deposit offer; it’s just broken down a little differently to an offer of this kind in the traditional sense.

Of course, the amount of bonus available is very small compared to some of the other casinos in our pickings today. But then again, not many people will be looking to max out hundreds of pounds in matched deposits.

MrQ is pretty new on the UK casino scene. It was only formed in August 2018, but it’s come a long way since then already and gained a lot of popularity among UK players. We’d be surprised if it wasn’t one of the bigger players on the market within the next few years.

And if you want to play online slots in the UK, make sure to have a look at what it has to offer.

The site itself is neatly designed and comes loaded with tons of slots, live casino games and bingo. Those into bingo will particularly love mrQ as it has won a bunch of awards for its portfolio of bingo games.

It’s worth bearing in mind, however, that these are the only types of games on offer so if you want to play the likes of blackjack and roulette, you’ll probably need to find another online casino site.

Mr Play casino hasn’t been around long, having only been established in 2017. But it’s certainly gone to town in curating games over the past few years, with a particular focus on live ones.

Now, with over 120 live casino games in its portfolio from some of the best software providers, such as Evolution Gaming, it’s making a claim for itself as one of the best live casino sites in the UK.

Mr Play’s website isn’t exactly the most pleasing to use in the world. The homepage feels a little clunky and tends to glitch out a little from time to time, but if you can get around that and you like live casino games and new slots UK, this could be the place for you.

And it’s not even just about the casino. Grosvenor also has one of the best UK betting sites out there, with tons of betting markets and great odds.

The one thing about Grosvenor that some players will find a little frustrating is the lack of certain deposit method options. You’re only able to pay with debit card, PayPal and one or two others. The likes of Skrill and Neteller are not available, and you can forget about crypto.

How We Selected the Best UK Casino Bonuses

Total Bonus Potential

First and foremost, the actual size of the bonus is key to deciding whether it’s worth taking up or not. Any tiny amounts probably aren’t worth your time unless they come with microscopic or non-existent wagering requirements.

On the flip side, large bonuses such as ‘100% up to £100’ or ‘100 bonus spins’ are a lot more tempting provided the terms and conditions are sensible.

Deposit Required

For ‘deposit required’ bonuses, you’ll need to meet a minimum and maximum deposit amount at the UK online casinos out there. We’re not fans of welcome bonuses that require a huge deposit in general, unless they offer huge potential rewards.

Remember, bonus funds are separate from your regular casino balance in that they’re subject to withdrawal terms.

Wagering Requirements and Time Limits

We looked at each casino’s wagering requirements to make sure they are fair and easy to achieve. For more info about wagering requirements keep reading to see where we explain the terms and conditions of UK casino bonuses.

As a general rule of thumb, 35x wagering requirements tend to be about average, but we have seen them be far higher than this. Anything too high is worth avoiding as it might get harder to claim your wins.

Game Contributions

Another crucial factor we took into consideration in our analysis is the game contributions towards the wagering requirements. Not all games contribute equally to meeting these requirements.

For instance, slots usually contribute 100%, but table games like blackjack and roulette might only contribute 10-20%.

Min and Max Bet limit

We also evaluated the minimum and maximum bet limits set by the casinos. These limits determine the least and most amounts you can wager in a single game round while playing with bonus funds.

Lower minimum bets are beneficial for players with smaller bankrolls, allowing them to extend their gameplay and potentially win more. On the other hand, higher maximum bets cater to high rollers who want to bet big.

Max Win Limit

We looked at the maximum win limit, which is the cap on the total amount you can win from the bonus. Some casinos might offer a seemingly generous bonus, but with a low max win limit, it might not be as attractive as it appears.

How are Casino Bonuses Calculated in the UK?

Casino bonuses in the UK are calculated based on the type of bonus and the casino’s terms and conditions. Welcome bonuses, often a major percentage of a player’s first deposit, and deposit bonuses work by matching a portion of the player’s deposit.

No deposit bonuses are a fixed amount given without requiring a deposit. However, these come with wagering requirements, a multiplier representing how many times a player must bet through a bonus before withdrawing winnings.

Different Types of UK Casino Bonuses

Here are some of the most common casino bonuses you’ll come across in the UK:

Welcome Bonuses

The welcome bonus is often the first interaction a new player has with a casino. This type of bonus is designed to entice new players to sign up and make their first deposit. It’s often a percentage match of the player’s initial deposit.

Deposit Bonuses

Deposit bonuses are similar to welcome bonuses but are available for existing players, too. These bonuses reward players each time they deposit money into their casino account. You can usually get these bonuses at mobile UK casinos, too!

Extra Spins

As the name suggests, extra spins give players additional spins on selected slot games, allowing them to play for real money without risking their own. Winnings from extra spins are often subject to wagering requirements.

Some casinos offer extra spins as a standalone bonus, while others combine it with other bonus types like the welcome bonus or deposit bonus. For example, our mrQ UK review shows that it has 30 extra spins for its users!

Cash Back

Cashback bonuses are a way for English online casinos to alleviate some of the sting from losses. This type of bonus returns a percentage of the player’s lost money over a specific period. For example, a casino may offer a 10% cashback bonus, meaning if a player loses £100 in a week, they would receive £10 back.

UK Casino Bonuses – Terms and Conditions You Should Know

Before you activate any of the online casino bonuses, make sure you undertsand their T&Cs. Here are some things to consider:

Bonus Funds

One of the primary terms associated with casino bonuses is the concept of bonus funds. When a casino awards you a bonus, the amount isn’t immediately added to your withdrawable balance. Instead, it’s often classified as ‘bonus funds’.

Wagering Requirements

Having to play through your bonus amount a handful of times before being able to withdraw your winnings is called ‘wagering’, and some casino bonuses will require you to do this more than others.

As a general rule of thumb, 35x wagering requirements tend to be about average, but some casinos have higher WRs.

Time Limits & Requirements

Betting limits dictate the maximum amount you can bet using your bonus funds. Violating these limits can often lead to the forfeiture of the bonus. Withdrawal limits set a cap on the amount of money you can withdraw from your bonus winnings. Keep in mind these limits when using promos.

Clearing the Bonus Funds

The process of releasing the bonus winning amount, often referred to as ‘clearing the bonus’, involves meeting the casino’s stipulated wagering requirements. For example, if a £100 bonus has a 10x wagering requirement, you would need to place £1000 worth of bets using the bonus funds before any winnings can be withdrawn.

Guide to the Top UK Casino Bonus Offers

Are Casino Bonuses Worth It?

Yes, casino bonuses can definitely be worth it, providing extra funds to play with, extending your gaming experience, and increasing your chances of winning.

What is a Casino Sign Up Bonus?

A casino sign up bonus, also known as a welcome bonus, is an incentive offered by real money online casinos to attract new players. It’s awarded to new players who sign up and make a qualifying deposit.

Can I Claim Another Bonus After My Welcome Bonus in the UK?

Any casino site worth its salt will keep its players interested by offering regular bonuses to their existing customers. These are unlikely to be as big as the welcome bonus but are still great to have.

These existing customer bonuses often include the likes of tournaments, extra matched deposit bonuses, and new games promos.

Which Online Casino has the Biggest Welcome Bonus UK?

Mr Play is known for one of the biggest welcome bonuses on the UK online casino market. The platform offers up to 200 GBP in three tiers, plus 100 bonus spins on the side.

What Casino Has the Best First Deposit Bonus?

MrQ has the best first-deposit bonus UK players can claim. Just by depositing 10 quid, you will receive 30 extra spins for the slot game Kraken’s Lair with no wagering attached to your casino winnings.

What is Casino Bonus Abuse?

Casino Bonus Abuse refers to the practices employed by some players to exploit casino bonuses unfairly.

These might include creating multiple accounts to claim the same bonus repeatedly, only playing low-risk games to meet wagering requirements, or hopping from one casino to another just to use their bonuses (a practice known as ‘bonus hunting’).

How Long Do I Have to Use My Bonus?

Any active bonus will have some kind of time limit attached to them. If you fail to activate or play through the bonus in this time, the bonus will become void and you could lose access to all of your winnings. That’s why it’s really important to check the terms and conditions before you get started!
