Since we’re an online casino guide, we will only recommend the best; let's confirm here and now to our readers, that we're very strict about the online casinos which we recommend on this website.

There’s a lot of work which goes on behind the scenes at Mega Fortune Jackpot Guide, so we’re sure of everything we’re recommending is of the highest standard and that you can trust the casinos that we advocate.

This also applies to the casino bonuses which we suggest too. If they’re not the best casino bonuses, then we won’t add them to this website.

Choosing the Best Casino Bonuses: Know The Difference

As we explained earlier, there are many different types of casino bonuses which online casinos will offer you during your time playing there. Before we get started explaining different sorts of casino bonuses, we should point out that you don’t have to take a casino bonus when making a deposit at an online casino if you don’t want to.

Taking a casino bonus is entirely your own choice and you can decline any bonuses if you prefer to just play with your own money, and only your own money. 

What Does "Wagering Requirements" Mean?

Online Casino bonuses are literally free casino money and you're able to win vast amounts of money by using them. This is why an online casino needs to protect itself slightly, and apply some terms and conditions to them, called ‘Wagering Requirements’. This is why some people don’t want to take a casino bonus, as some (but totally do-able !) restrictions will apply.

Wagering Requirements simply mean that if you take money from the bonus money, and you want to cash out, then you will need to wager and bet a minimum amount before you can actually cash it out.

We always recommend reading any Bonus Terms and Conditions before you play, so you know what’s expected of you and if there are any games you want to play which may be excluded from the wagering requirements.  As long as you know how it works, then casino bonuses can actually help you play for longer, bet for higher and win more money.

The Purposes of Casino Bonuses

The purposes of casino bonuses are purely to attract you to the best online gambling sites which suits you the most, with the bonus which attracts you the best. There are many different online casinos and therefore casino bonuses and, as everybody is different, the great thing is there's so many to choose from! 

Also, it’s to attract you to a specific online casino and not their competitors. Any bonus money online casinos give you is actually 'real money' and not ‘play money’ and you can win real prizes with it.

So therefore, casino bonuses are there to help you play for longer, in some cases bet for higher amounts and generally offer you more enjoyment and entertainment.

Once you’ve taken the original casino bonus that you’ll be given to you make your first deposit at an online casino, it won’t be long before you’ll be offered a further sort of casino bonus or rewards for your loyalty. Have a look below; as we help explain the different kinds of common casino bonuses and what to expect from them.

Different Types of Casino Bonuses

There are a few of different types of casino bonuses which are on offer to all players who are looking to play online slots and casino games. Have a look below for each so you know what to expect when you’re looking for when you choose a new slots site or gambling site:

Deposit Bonuses

Deposit Bonuses are the most common type of casino bonus you can get, and you’ll be offered a deposit bonus when you play in a new online casino for the first time. The casino will match your deposit and double up to a certain amount, to a specified maximum so you will have double to play with. Each casino differs to one another, and you might find some casino bonuses are spread out over your first 2-4 deposits, which can be the better value and some are more than others.

Free Spins Bonuses

Free Spins are very widespread and usually online casinos will not only give you a deposit bonus when you get started, but also free spins on a specific online slot machine. A lot of online casinos will give new players free spins on a very iconic online slot machine called Starburst.

Sometimes, free spins will be given simply when you register, and more free spins will follow when you make a deposit, and some will require a deposit from the beginning. Usually, you’ll get far more when you do make a deposit, but some casinos will give you 20 free spins or similar, so it enables you to try out a slot for real and see what they are all about. Choose a free spins bonus which you think is best for you. 

Reload Bonuses

Having used your deposit bonus, then online casinos are keen to keep your custom and will offer you what are called ‘reload bonuses’ from time to time. These are usually given on a weekly basis, so that every time you make a deposit, you’ll be rewarded with some unbeatable value to bump up your casino balance which will enable you to play more.

High Roller & VIP Bonuses / Reward Plans 

Some people like to bet big and will want a large bonus to get started with, usually if they’re planning to deposit a large amount. Some online casinos offer large bonuses so that the casino player who wants to bet big every bet or slot spin, can do so. 

This is why, if you intend to deposit a lot of money to do this, you’ll want a large bonus to be credited so that you’ll be able to play for longer periods of time. If this sounds like you, simply look out for the large bonuses which are given on your first deposit or contact the VIP department at any online casino to see what they’re willing to offer you.

That’s a brief rundown of how online casino bonuses work. Remember, most casino bonuses can differ from one casino to the next, so pick the one which is best suited to you.

All of the online casinos we recommend on Mega Fortune Slot Guide are all known to give the best casino bonuses, from the time of your first deposit, with high value ongoing rewards and promotions as well plus also the chance to play Mega Fortune Slot
