What Are Casino Bonuses & Why They Matter

Welcome Bonuses - What They Offer

A casino welcome bonus is available exclusively to new customers signing up with an online casino for the first time. It is a valuable and exciting offer often containing more than one promotion to help players get the most out of their first time playing. An example of casino welcome bonuses could be a 100% Deposit Bonus + 100 Free Spins. The purpose of a welcome bonus is to attract new players to a site and encourage them to choose that site over others. The rewards enable players to get to know a site and try out some games risk-free.

Free Spins & No-Deposit Offers

Free spins no deposit are the latest casino bonuses to be popular amongst players. These provide players with the opportunity to play some top slot games without having to spend any money depositing into their accounts first. Some examples of free spins no deposit offers include Get 50 Free Spins No Deposit and 25 Free Spins No Deposit. These enable players, both new and existing, to enjoy playing games risk-free and worry-free, and try out new titles they may not have otherwise played. 

Reload, Cashback & Loyalty Bonuses

The best casino reload bonuses and cashback offers can be found fairly frequently at online casinos and can be claimed by both new and existing players. These can see players receive a percentage of their funds spent at a casino back in the form of bonus funds or cash to use for further play without incurring additional costs. It gives players a chance to try out different games or play more of their favourite games without the risk. Loyalty bonuses, meanwhile, are offers available to returning players and provide extra chances to benefit frequently. Examples of reload or cashback online casino bonuses include: 10 up to £100 or 10 Weekly Cashback. Loyalty rewards can be anything from extra free spins, cashback, reload offers, and deposit offers.

High Roller / VIP Bonuses

Some additional casino bonuses available across online casinos include high roller and VIP bonuses. These can be great for those who prefer to spend a bit more when playing, and can offer a lot more value than a casino welcome bonus. These can be some of the biggest casino bonuses, for example 100 up to £1,000, 200 up to £500, and so on. VIP bonuses are available to those who are a part of the VIP program or scheme at a platform, and can contain extra chances to claim free spins, cashback, and even some exclusive casino bonuses.

How to Evaluate & Compare Casino Bonuses

When it comes to choosing the best casino bonuses UK, there are certain criteria that we check against to ensure that each is worthwhile. We have provided more on our key criteria below and how we handpick the latest online casino bonuses.

Wagering Requirements – The Playthrough Trap

We ensure that we check each and every new casino bonuses relevant wagering requirements before recommending it to players. This ensures that players are aware of the expenditure required from their side and are fully informed before claiming an offer. The majority of online best casino bonuses will have some form of wagering requirement, such as 10x, 30x and so on. A common mistake for players is not checking the wagering requirements, which can result in unplanned spending to keep any winnings.

Maximum Payouts & Game Restrictions

Ensure you check the terms and conditions of any offer you are considering to claim, as this will help you maximise payouts and understand game restrictions. This will help set players' expectations for how much they can expect to win when claiming an offer, as well as which games they can play using the latest casino bonuses they have claimed. Not checking this information can lead to playing games where players can not benefit from the bonus, as well as not being able to see all of their expected winnings.

Eligible Payment Methods & Exclusions

It is essential to be aware of the qualifying payment methods when claiming any of the best UK casino bonuses. This means players can make eligible deposits and not miss out on claiming their rewards. There can also be exclusions on certain payment methods in particular, as well as game exclusions, so to receive your offer and rewards, it is vital to check for the qualifying payment methods and any exclusions in place.

Bonus Expiry and Withdrawal Conditions

Whether you are claiming casino welcome bonuses or any casino bonus, all of them will have expiry dates attached to them. It is essential to check these so that players can use their rewards before they are lost. This typically ranges from seven to 30 days, depending on the casino and the specific offer. It is also common for online casino bonuses to have withdrawal conditions, such as payment method restrictions, time limits, and other requirements.

In addition to verifying your account, players must also make a qualifying and eligible deposit into their account.

Remember that when playing at any online casino and claiming any of the latest no deposit casino bonuses UK or any other offers, you are firstly playing at a reputable and licensed site. Look for the licensing from the United Kingdom Gambling Commission (UKGC) or the Malta Gaming Authority (MGA). 

Always practice responsible gambling habits whenever possible when claiming casino bonuses. Set yourself a budget that you can afford and stick to, and utilise the various responsible gambling tools available across online casinos. 

Mobile Casino Bonuses: Are They Different?

So, are mobile casinos different from regular online casinos? We have looked into this in more detail below.

Mobile-Specific Bonuses

Many UK casinos now offer exclusive offers for mobile players when playing on the casino app. These can include mobile casino sign-up offers, free spins, and deposit match bonuses. This is often done to try to entice players to download and play on the casino app rather than the website.

Pros and Cons of Mobile Bonuses

There are many advantages and disadvantages to mobile casino bonuses, and we have looked at some of them below.

Examples

Pub Casino, bet365, and Jackpot City all provide top mobile-friendly platforms with dedicated apps that can be downloaded to devices. When playing on these platforms, whether via mobile browser or on the app, players can expect to come across exclusive mobile casino offers and take advantage of them while out and about.

Tips

We always think it is worth checking out reviews left by players just like you who have experienced the platform for themselves. Check the app store reviews for real opinions on the user experience, as well as looking for reviews of bonuses, games, and the general casino experience.

High Roller Bonuses and VIP Programs

Available at many online casinos are exclusive casino offers for different types of players and their playing habits. We have looked at high roller and VIP bonuses in more detail below.

What Are High Roller Bonuses?

High roller casino bonus offers are special promotions for players who deposit larger amounts into their accounts. These typically offer perks such as bigger match percentages, lower wagering requirements or VIP perks.

Benefits of VIP Programs

Exclusive casino VIP programs are exclusively for frequent returning players to a casino that offer enhanced benefits to a player's casino experience as a way of saying thank you for your loyalty. Some VIP benefits and perks that qualifying players can expect to come across are things such as personal account managers, faster withdrawals, exclusive events, merchandise, higher deposit limits,and free spins, among much, much more!

Eligibility

High roller casino bonuses typically require much higher initial deposits than your regular casino bonus offers. Due to this, this type of bonus is often more suitable for more experienced or dedicated players at online casinos who are comfortable with spending large amounts of money.

Examples

Neptune Play, bet365, and Netbet are all top online casinos recognised by customers for offering generous bonuses. This includes high-roller bonuses and enticing and rewarding VIP/Loyalty schemes. For example, players at Netbet can climb up a ladder of seven tiers of rewards, earning great benefits the more they play.

What are Bonus Codes and Do I Need Them Every Time?

Casino bonus codes are unique codes that are often what players must enter at a site in order to benefit from an offer that is available. The codes unlock the likes of welcome bonuses, free spins, deposit matches, cashback offers, and lots of other promotional offers. Bonus codes can consist of both letters and numbers and must be entered into the promo code box on a page when claiming to ensure it is applied, and you receive your rewards.

However, players do not necessarily always need casino bonus codes every time they want to claim an offer. Some promotions will not require a code in order to be benefitted from and will instead be applied automatically when requirements are met or simply by players selecting a ‘claim’ button. Always check the terms and conditions of promotions in order to see whether a promo code is required.

Bonus codes allow casino sites to track specific campaigns or tailor offers to specific players to claim, preventing anyone who does not qualify from benefitting. Casino bonus codes are especially useful for targeted promotions or limited time deals.

Responsible Gambling

When playing online and claiming the latest casino bonuses, it is important that players continually practice responsible gambling. Take steps to control your spending by setting a budget that you can afford and stick to, and set alarms to monitor the time you spend at a site.

Make sure that you use the responsible gambling tools available to you at various sites and set deposit limits on your account. Make use of reality check and time management tools, spend management tools, timeouts, self-exclusions, and account closure options, all designed to maintain healthy gambling habits.

There are several responsible gambling tools and resources that players can use for further support, including GambleAware, GamCare, Gamblers Anonymous, and various other gambling charities and helplines.

Summary: Maximise Your Bonus Smartly
