Casino Bonuses: Everything You Need To Know 

Casino bonuses come in many shape and sizes and almost all online casinos offer them to customers. If you have ever wondered why a casino would give you something for free, then sure, we would also wonder what the catch is too! But, the truth be told is that casinos offer bonuses for a couple of different reasons.

Why Are There Casino Bonuses?

Ultimately, online casinos are looking to attract you to their casino over any another casino which would be their competitor. Obviously, there are more things to look for when you are choosing a new casino to play at but one of them is the casino bonuses they offer and that’s what we’re going to focus on right now.

Below we list the different kinds of casino bonuses you’ll likely to encounter on your casino journey, some might be more suitable to you than others but they’re all there for the taking and up for grabs. Also, let us just add, below we also list only the top, most recommended online casinos and ones which also have a UK gambling license.

The team here at onlineslot.org.uk have tried and tested each casino that we recommend and they have passed our merit with flying colours! Seriously though, we have run checks on their banking systems, how fast we were able to withdraw, check the game choice, customer service, bonuses, reputation, parent company, negative news, and hidden information such as wagering requirements – you name it, we checked and came up with a list below of the few best casinos that made the cut. We did have a bit of fun checking them out of course!

Free Spins Bonuses: Explained

Free spins or free rounds is the name given to a bonus where a casino will give you literally a number of free spins on any online video slot. Sometimes they are really free and all you’ll need to do is register an account at said casino and they will be credited in your account. Some offer free spins when you will get them as a free addition, when you make your first deposit. Either way - they are free and something you can use to try a new casino out before you play for real or perhaps try a new slot.

Usually free spins bonuses are also given to existing casino customers as well, for example when there is a new slot launched and the casino want to try them out.

Free spins are considered free but the online casino would need to cover themselves a bit from risk, so they set what’s called ‘Wagering Requirements’ on the free spins (apart from Thrills and Guts Casino who have wager free spins!). Usually a normal wagering requirement are around x35 of bonus amount, but always check the small terms and conditions before you start so you know what to expect if you win something.

Casino Deposit Match Up Bonus: Explained

A casino match up bonus is by far one of the best casino bonuses you can take and the way they work is they reward you when you put money into a casino – commonly known as making a deposit! They are usually a percentage and then a maximum currency amount, say for example: 100% up to £100.

This means that when you deposit £100, the casino will match it (up to a maximum €100) and give you another hundred in bonus money. Now, you might be asking why! Would a casino do that? Give away free money like that? But the answer is simple... They want you to be able to play for longer, make you money go farther and also bet how you want.

Some slots sometimes need a higher bet to get into bonus round, like for example, Mega fortune. Also, some slots have a high volatility rate so they may eat you bankroll for longer periods of time without a win, but when you win – you’ll win big. The casino bonus is designed to help you and cut your risk of losing your money as well, so it is a win-win situation. There is a catch of course which all casinos are only happy to disclose and tell you about.

They are giving you away real cash money but they have to protect themselves too. Imagine if everyone could win a fortune at their expense, from these casino bonuses? The way they protect themselves is by attaching wagering requirements to these bonuses. Most of them work in the way of the formula: Deposit + Bonus x 35 = which is the magic number you’ll need to wager (bet for) until any restrictions are lifted and you’ll be allowed to withdraw any of your winnings you’ve made by claiming their bonus.

It’s very popular bonus and there’s nothing else to it. Casino Bonuses are there to help you. Do always read all terms and conditions before you start, our recommended casinos only carry the best and fair terms and conditions. If you are still unsure, all casinos welcome you to contact their customer support department o ask any question you like – they’ll be able to put your mind at ease.

Free Cash Bonuses: What You Need To Know

Free casino bonuses are a bit rarer these days as most free bonuses are given in the form of free spins. However, some casinos do still offer free cash bonuses and they usually are credited when you register an account. Usually free cash bonuses have aforementioned wagering requirements attached to them, so always read the terms and conditions before you start.

Having said that, it’s always good to view free casinos bonuses as a bit of real fun and not something to make you rich as the free bonuses are usually a smaller amount, for example €5. But, it is a good way to test a new casino for real.

You never know though, wins can happens from free spins and free bonuses. There was a winner on Mega Fortune one time in 2011, who won his fortune from a free casino bonus. Of course, he had some wagering requirements to fill, but then I don’t think it would have been a problem to fulfil them!

Reload Bonuses: Explained

It’s usual that loyal casino players regularly enjoy ‘reload’ bonuses that casinos offer from time to time. These are straight forward bonuses like the deposit bonuses but act like follow bonuses every so often.

VIP Program – Get Spoiled For Being Loyal, It's that Simple!

Lastly, almost every casino will offer a VIP program or loyalty rewards. Whatever you want to call them, the aim is to offer players extra bonuses and promotions for their loyalty.

These days, almost every player is rewarded and awarded on a scale. In our opinion, the best casinos offer this type of program, thus not to single any type of player out. We’re all different, aren’t we? Suffice to say, the more you play the more you get back as with any loyalty system.

High roller casino bonuses are also up for grabs so if you are a high roller, then look out and inquire about a casinos VIP program and their high roller bonuses so you get the most out of your bankroll and the best service you deserve too.
