What is a Casino Bonus?
Casino bonuses some in quite a few different shapes and sizes but all have the same desired effect: To give you extra money when you make a deposit in the casino. The extra money is there to help double up whatever you put into the casino of your own money, up to a maximum amount. With this combined money, you can apply your favourite slots and casino games for longer, sometimes betting higher to achieve bigger results and wins.
As an example, let’s think about a standard casino bonus which online casinos usually offer to get started. They’re usually called ‘Welcome Bonuses’ or ‘First Deposit Bonuses’ and they usually give you a percentage up to a maximum monetary amount. For example: 100% up to €500. In this case, if you register at an online casino offering this bonus, and deposited €100, then the casino would match that by 100% and give you €100 in casino bonuses. This would then in actual fact give you a total of €200 to play in the casino.
As we said before, there are many different kinds of casino bonuses, each varying between casino to casino, and we just pointed out the most basic one (but still good). Some online casinos will offer you a large amount whereby that’s split and given across the first 3-5 deposits you make for example. These are by far our favourite types of online casino bonuses as it helps you maximise the bonus and also your deposits, and therefore, it also means longer playing time in the casinos, than a onetime bonus.
Casino Reload Bonuses
Once you have used your welcome bonus then don’t think that that’s it and you need to hunt for another casino (of which you are free to do if you so wish) because another bonus won’t be too far away. They’re usually given on other deposits you make, either they will be emailed to you or a note will pop up in your account, so that if you make subsequent deposits, then you’ll get something for your money and some extra value. These are generally seen and referred to as ‘Reload Bonuses’. It’s a way of an online casino thanking you for your loyalty and usually forms part of an online casinos reward programs. Most online casinos offer cash back, reload bonuses and free spins bonuses as part of a rewards system, plus many other fun things, such as giveaways and trips. So it does definitely pay to stay loyal at one casino that you consider your favourite. Most reload bonuses will be the same as a deposit bonus, a percentage and an ‘up to’ amount.
Free Spins Bonuses
These are casino bonuses but they just come in a different format. Usually, when you join a new online casino or new slots site, you’ll take the welcome bonus as we explained above, and usually on top of those welcome bonuses, you’ll also get a free spins bonus, which really add the cherry on the top. Free Spins are exactly what they sound like – they’re free spins on an online slot machine. Usually free spins bonuses are given on popular Netent slots, like Starburst slot for example, and can vary from casino to casino. Some casinos it possible to get up to a couple of hundred free spins on Netent slots, which usually will require a small deposit. Sometimes however, free spins bonuses will be given for free, with no deposit required. These are called free spins no deposit bonuses and most online casinos will offer them at the time of registration so you can try them casino for free.
After that, free spins bonuses are given at frequent intervals and usually will be added on to a deposit you make. This is a good way to add value to your time in the casino, so make sure you look out for an email to you can take full advantage of getting them. Usually, when a new Netent slot is released, Netent being seen by most in the online gambling world as providing the best online slots, many online casinos take this chance to increase the hype of the slots launch, by giving you free spins on the new slot.
Sometimes, free spins are actually given on progressive jackpots although it is rare you can find them it’s not uncommon for Casumo casino to offer free spins on Mega Fortune Jackpot Slot now and then.
Wagering Requirements
The fact is that online casinos are giving you free money, and it’s not just a play credit – the bonuses are real money of which you can win enormous amounts from. So it’s only right that they add some terms and conditions to the bonuses that you take and play for real with. If you claim a casino bonus when you have made a deposit, then your money and the bonus money will be subject to what’s called ‘Wagering’ or ‘Play through’ requirements and we always recommend that you read all about them before you start playing. Sometimes, games that you might want to play do not count towards the wagering requirements of some bonuses, for example, table games, so do make sure you read the Terms and Conditions of the bonus or feel free to ask the online casinos support department. The play though is usually at around x35 the bonus and deposit amount, but it does vary from casino to casino, which is why we always say ‘read the label'!
You don’t have to take a casino bonus if you don’t wish to be subject to any requirements or you don’t want the extra casino cash. Just decline it via the customer support if it’s applied automatically or don’t put in any required bonus code if you don’t want it.
This is just a roundup of the world of online casino bonuses, so take a look above as we have listed all the current and best casino bonuses you can find online, only at the most trusted and reputable online casinos and gambling sites which are licensed and regulated. Enjoy!
