Parimatch Casino – Wager £10 Get £30 + 50 Free Spins

With the Parimatch Casino offer, you can get £30 in bonuses, as well as 50 free spins on their Starburst game, which is one of the most popular games to play on Parimatch Casino. It’s one of the strongest casino bonus offers in the business, as not only are they offer free spins to their customers, but they’re also offering £30 in bonuses to use on selected games, which is more than plenty of other operators in the casino betting industry.

Parimatch are a well-respected operator in the betting industry, and it won’t be at all surprising to hear that their casino offer catches the eye for all the right reasons. One of the potential issues within the Parimatch Casino sign up offer is that new customers will be required to wager the bonus at least 40 times before a withdrawal request can be made by the user.

Ladbrokes Casino – Bet £10 Get £30 + 30 Free Spins

You’ll be able to get £30 in casino bonuses, as well as 30 free spins to use on Fishin Frenzy Megaways, which is a hugely popular choice of game amongst many casino bettors out there.

Ladbrokes are a great casino betting site, and with a sportsbook that catches the eye as well, they’re worth considering using. They finished inside the top-five at the UK Bookmaker Awards for Best Banking Options, so you won’t be short of withdrawal methods for any winnings you get from the Ladbrokes casino offer.

JeffBet Casino – 100% Welcome Bonus up to £100 + 50 Free Spins on Rainbow Riches Megaways

JeffBet Casino are still a relatively new name in the casino industry, but that hasn’t stopped them from making a name for themselves for all the right reasons. They’ve got a strong sign up offer for their new customers, as they’re offering a 100% welcome bonus up to the value of £100.

You’ll also be credited with 50 free spins to use on Rainbow Riches Megaways after you’ve met the qualifying criteria attached to the casino bonus, and with plenty of games to choose from, you won’t be short of options! The casino bonus is available for 30 days before expiring, which is more than some of the other casino operators’ sign up offers.

Betfair Casino – Get 50 Free Spins When You Join

Betfair Casino are another great choice to consider when looking to sign up with a strong casino offer. They’re offering their new customers 50 free spins when they sign up with no deposit needed, which makes it a more than enticing offer to get involved with if you haven’t already.

You’ll have the chance to get a further 100 free spins to use on Betfair Casino when you deposit and wager funds of £10. So there’s plenty on offer early on from this popular operator, and with a sportsbook and betting exchange that also catches the eye.

Kwiff Casino – Grab up to 200 Cash Free Spins on Book of Dead! Wager £20 on slots and Get 40 Cash Free Spins for five consecutive days.

Kwiff Casino’s sign up offer is worthy of a mention, as they’re offering new customers up to 200 free spins in total if they meet a certain qualifying criteria. It’s a slightly different casino bonus compared to other sites, as they require you to stake £20 on each day if you’re looking to get the maximum bonus of 200 free spins to use on Book of Dead! Of course, staking £100 in the space of five consecutive days might not be for everyone, and this particular sign up offer might be more focused on bettors with a larger casino betting budget.

Our experience with Kwiff Casino has been a pleasant one though, with their site being easy to use and find everything you need to know. They also have you covered with a range of different games, which all feature varying stakes, which makes it the ideal casino site to use for bettors that have different budgets for casino betting.

What makes the Best Casino Bonus?

There’s many different factors that make up the best online casino bonus, and each bettor will have their own preference as to what they prioritise within a casino welcome bonus.

We’ll delve deeper into these factors, in the hope that it provides you with further insight into the importance of some of these points.

Size of the Bonus

This is one of the most obvious things that a bettor will look into when they’re searching for the best casino bonus. You’re going to want to have a casino bonus that offers a sizeable amount, and if the bonus is less than that of the original deposit needing for that casino sign up offer, then it’s well worth looking elsewhere.

There are plenty of different casino offers around that offer some potentially eye-opening casino bonuses, but it’s hugely important that you read the terms and conditions of each offer, as some potentially need you to deposit a larger amount than you originally planned to.

Wagering Requirements

Arguably, the wagering requirements attached to an online casino bonus are one of the most important factors to take into account when looking to sign up to a new casino site. It often gets missed by many bettors, as they’ll often be focused on the deposit and size of the bonus on offer from the specific operator.

Many casino bonuses often have wagering requirements included, which means that any funds won from the bonus will have to be used a certain amount of times before a withdrawal can be made to your chosen withdrawal method. The best casino offers will have minimal wagering requirements, as that’ll maximise the chances of the bettor coming away with some profit from the bonus on offer from the casino site they’re using.

Eligible Payment Methods

The majority of casino sites often have similar payment methods that are available to use on their sign up offers, which often includes Visa Debit and Bank Transfer. E-wallets such as PayPal, Skrill, and Neteller often aren’t accessible for most casino bonuses, and if you’re keen on using those payment methods, then you might struggle to find a suitable online casino bonus that accepts your chosen deposit option.

Expiry Date of Bonus

It’s worth remembering that each bonus attached to a sign up offer will have an expiry date on when the bonus funds can be used. If you go beyond this time without using them, then the bonus will be removed from your account. The majority of casino bonuses are typically available for seven days, but the best casino offers will have bonuses which are available to use for up to 30 days in some cases.

Eligible Games to use Bonus

Some casino offers have bonuses which can only be used on certain games that feature on their site. This isn’t always a ‘deal-breaker’ for most bettors, as they’re ultimately keen to turn the bonus into cash which they can then withdraw to their chosen payment method.

However, if you’re keen to stick with certain games on a casino site, then you’ll be hard-pushed to find a casino offer that suits you, as many different operators have different games in which their casino bonuses are available on.

Types of Casino Bonus

There are plenty of different types of casino bonus that you can use with various different casino sites, and so it’s important to understand which type might be best suited for you, as of course, you’ll have different budgets for casino betting compared to others.

We’ll take you through some examples of the various types of casino bonus that you can find with the most popular casino sites in the industry.

No Deposit Casino Bonus

A no deposit casino bonus isn’t all that common with most casino operators, but when they are available, they’re popular amongst bettors, who often look to win money without depositing any funds into their account after they sign up. It is worth remembering that you should look into any potential wagering requirements that are attached to any no deposit casino bonuses, as these can potentially limit your chance of winning funds that you can eventually withdraw to your chosen withdrawal method.

Free Spins No Deposit Bonus

Free spins no deposit bonus are similar to that of a no deposit casino bonus, but the difference is, you’ll be credited with free spins, as opposed to a generic casino bonus.

The likes of Betfair and Sky Vegas are some of the best casino offers in the industry, as they’re offering their new customers free spins when signing up, and don’t require any deposit to obtain the free spins on offer. You’ll then be able to withdraw any winnings to your chosen withdrawal option.

Deposit Match Casino Bonus

This type of casino offer is becoming increasingly more common nowadays, with the bettor having their first deposit matched in casino bonuses. However, it’s worth remembering that the bonus isn’t always 100%, so remember to read through the terms and conditions of the casino sign up offer before you make your first deposit with the operator.

JeffBet Casino and Casinomite are some of the newer casino sites that have a deposit match casino bonus as their sign up offer, which could see you get a casino bonus of up to £100 depending on your first deposit with these operators. JeffBet Casino in particular catch the eye, as they’re offering a deposit match casino bonus, as well as free spins attached to their sign up offer, which is highly likely to entice new customers into signing up with them.

Cashback Bonuses

Cashback bonuses typically offer new customers a percentage back on their potential losses they’ve had from their first deposit. Obviously, it’s not an ideal scenario to potentially make a loss from your first deposit with your chosen casino site, but it’s always somewhat comforting that you’ll receive some of your funds back in casino bonuses if the operator is running a cashback bonus.

Reload Bonuses

A reload casino bonus can be a slightly more complicated online casino bonus to obtain, but they can sometimes be beneficial to those that are looking to make more than one deposit. Reload bonuses will offer you further bonuses after your first deposit, which is likely to prove popular amongst new customers.

The likes of Sky Vegas are a good example of this type of casino bonus, as they’re offering new customers further free spins when they make a second deposit after receiving the first part of their casino welcome offer.

Free Spins

Some casino offers can offer you free spins when you deposit and wager a certain amount of funds, and with this type of casino offer being easy to understand and follow, it’s clear to see why it’s a popular choice for punters.

Jackpotjoy and Betfair Casino are good examples of casino sites that offer their customers free spins within their casino sign up offer. There’s plenty of games in which you can use the free spins on as well, which is another positive to look forward to with these operators in particular.
