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. If you’re looking for a premium live casino experience, some operators offer exclusive bonuses tailored for live dealer games.

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.

If you’re keen to stick with certain games on a casino site, then it’s even more crucial to check the intricacies of the welcome offers T&Cs, as the eligible games will vary greatly depending on the different casino sites.

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.

Casinomite are one of the new 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 also 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.
