Online Casino Bonuses: Guide to the Best Bonuses & Casino Promotions
Online casino in this day and age is a social online phenomenon, and is seen as a fun past time with entertainment value, a bit like live Bingo was when it first became popular, as thousands of people enjoy it every single day.
No longer do you need to travel and go to a 'Land Based' Casino, although, we admit – that is fun sometimes and definitely a treat.
But the fact is, that modern technology and fast internet has made online casino extremely accessible and fun! It’s more like playing online adventures with some extra pizzazz thrown into the mix. A little bit of a bet never hurt anyone, and the online slots that you can play today are simply amazing and downright entertaining.

Online Casino Popularity: Choosing The Right Casino For Your Playing Style
Online casinos all offer a casino bonus one way or another. They come in all different shapes and sizes and are there for a couple of different reasons. First of all, it’s obvious that an online casino will give you a bonus to attract you to their casino in the first place. This is marketing 101 and no different to an online shop sale giving you discount. Since there are many online casinos in the market these days, then online casino bonuses are usually very competitive. Unless you play at some really, really large corporate casinos that is, but trust us; they’re not so much fun anyway.
The other reasons why online casinos offer casino bonuses in many shapes and sizes is basically, contrary to what you might believe – is that they actually want you, their customer, to enjoy your time in the casino, play for a long time and get as much out of that as possible.
Bonuses enable you to play for a longer time if you take a bonus than if you didn’t. Casino bonuses also help you to bet higher, which is sometimes is important if you have an eye on a progressive jackpots or bigger wins; as you always usually have to bet a little bit higher to achieve more.
For these reasons casino bonuses exist one shape, form or another. We've highlighted some of the most common casino bonuses below, and also we can recommend the best online casinos to you. How do we know what’s best? Well, we like you, play regularly at online casinos and have done so since many, many years.
We've tried some great casinos and always try new casinos so we know what they’re all about. We’ve also tried not so good online casinos and our prmis to you is that you’ll never see them on these pages.
One thing we need to mention is that you don’t need to take a casino bonus if you don’t want to. It’s totally fine if you want to bet only, with your own money, After all, all casino bonuses are usually subject to terms and conditions. But let us be clear about the fact that all bonuses at reputable casinos (and therefore only ones we recommend) usually carry a wagering requirement ('play through' before you can cash out any winnings) that are industry standard and deemed fair.
Why Are There Wagering Requirements?
If you think about the fact that online casinos give out their own money in the form of a bonus to almost every customer, then there has to be some kind of term attached otherwise it would be a ‘too good to be true’ situation, and we all know how that works.
Therefore, casinos want to help you but they also of course need to protect themselves as they can not only give you free money here, there and everywhere. Let’s not forget that you can also win a lot of winnings with that (bous) money so that’s why wagering requirements exist.
They are achievable and standard, but if you prefer to have no requirements attached to your casino bankroll, then make sure you politely decline the bonus. If you’re not sure how, then you can contact a casinos customer service team to ask them to remove it.
Make sure you don’t play a single spin if a casino bonus pops up automatically, as it could be considered that you intended to use it and therefore the wagering requirements applied.
Popular Casino Bonuses: FreeSpins
Freespins are the most common type of casino bonus and are given to new customers to help them try on casino sites or maybe a new slot that’s just been launched.
It’s common for Freespins to be given on Netent slots such as Starburst and Spinata Grande Slot. Freespins can vary in amount from casino to casino. You'll also find that some Freespins are given upon registration, whereas some are given on deposit. Whichever way you look at it, they’re given for free at some point.
The most common amount of freespins given is usually around 20-50 freespins, but you will see below that there are many more you can claim. Usually, the more Freespins on offer, the more it will mean that they are given in stages on a series of deposits, with a deposit bonus to match of course.
It’s totally possible for you to win money with Freespins, but bear in mind that the main aim of a Freespins bonus is for you to try out new things for free. And hey, if you win something – awesome for you!
Casino Deposit Bonuses
As we highlighted above, casino deposit bonuses vary, but are usually in a match up format, such as 100% up to £200. This means, if you deposit £100, then the casino will match that amount with another £100, leaving you with a doubled up amount of £200 to play with. Bear in mind however, that the maximum bonus which will be given in this case is £200.
If you are looking for more, for example special 'Hgh Roller' bonuses, it’s always a good idea to contact the support centre of said casino, as all casinos we recommend on MegaFortune.org.uk will offer a VIP Reward or Loyalty program.
Free Casino Bonuses
These normally come in the free spins format above but some casinos do offer an amount of free casino cash for you to try the casino out. This is a handy little bonus as it’d then entirely up to you where you spend the cash: If you don’t fancy playing slots, then you can play other types of casino games such as Blackjack or Baccarat.
Last Word From Us
Make sure before you take any casino bonus, deposit or free that you are fully aware of the terms and conditions applied to it. As we said, on this site we only recommend to you the best casinos and also the most fair and reputable one but it’s up to you to make sure you understand how bonuses works, most of the time they’re a great help in helping you enjoy online casino to the fullest. But if you know the terms and conditions and also the wagering requirements, then no little surprises can occur, can they?
